Valve, in particular a valve of a radiator

 

The invention relates to mechanical engineering, in particular to valves installed in the piping of the heating system. Valve, in particular a valve of a radiator that includes a housing having an inlet connection and outlet connection element. Between these connecting elements are locking device with the valve element and the valve seat. The valve body has an internal cavity. This cavity is communicated through the inlet with the inlet connecting element and through the outlet with the outlet connecting element. The valve seat is located at the first end of the channel inside the saddle. The latter is installed in the inner cavity can be rotated between a first position in which the second end of the channel is aligned with the inlet hole, and a second position in which the second end of the channel is aligned with the outlet. Between the valve body and surrounding the channel wall is formed by the free cavity. The invention is aimed at ensuring the operation of the valve regardless of the direction of flow of the stream. 13 C.p. f-crystals, 3 ill.

The invention relates to a valve, in particular the valve radiator heating is, between which is located a locking device with a valve element and a node of the valve seats.

Such a valve constituting the valve of the radiator, is known from WO 99/22282.

Typically, for a valve of a radiator of this type, the direction of water flow is set and indicated by an arrow on the outer side of the housing. The direction of flow you need to pay attention to avoid damage that can be detected primarily by the unpleasant noise. For normal operation of the valve side of the locking device with the valve seat of the debt to be connected with the inlet connecting element, and the side locking device with valve element with the outlet connecting element. When the movement of the valve element to the valve seat there is a gradual throttling of flowing water. The "correct" way to work problems do not usually arise.

This is not the case, if the valve is not properly connected, i.e. if the supply piping of the heating system is connected to the outlet connecting element. In this case the water flows through the valve element to the valve seat and thence into the inlet of the connecting element. When closing the valve the valve element moves to the saddle. If novena is closed, as a result, both immediately increases the pressure in the outlet of the connecting element. This increase of pressure is shown as hydraulic shock, which not only creates an unpleasant noise, but can cause damage in the piping system. Water hammer can be caused also by an external pulse, for example, with the rapid opening or closing of the other valve when starting or stopping a pump, or other reasons. These reasons, which are not yet fully understood, especially critical if the valve is not installed correctly.

Danger improper installation of the valves of the radiators is not only due to the low qualification of personnel, which sets the valve, but will sink that in the old docks or facilities, it is impossible to determine exactly what the pipeline is used to supply water heating system, and which for its removal.

The basis of the invention lies task is to ensure that the valve regardless of the direction of flow of the stream.

This task is solved in that the valve body has an internal cavity, built-in through the inlet with the inlet connecting element and through the outlet from the exhaust seedling in the inner cavity can be rotated between a first position, in which the second end of the channel is aligned with the inlet hole, and a second position in which the second end of the channel is aligned with the outlet, and between the valve body and surrounding the channel wall is formed by the free cavity.

Thus, the body of the seat forms an insert in the valve body, which can always be positioned so that the direction of leakage flow through the valve will be "correct". If the valve is connected so that water is supplied to the input coupling element, the casing seat is positioned so that water may flow into the channel from the inlet connecting element. As the channel approaches the valve seat, the valve element is flown from the saddle. When the valve element is lifted from the seat, the water can flow down through the free cavity formed between the valve body and the housing seat. The outlet in this case is open, so that water can flow through the outlet of the connecting element. If the valve is selected otherwise, i.e., water flows through the outlet of the connecting element, the body of the saddle just turn into the second position. In this case the water enters the channel through the outlet connecting element and the exhaust from the bathing place in the inner cavity, and the second end of the channel is moved back to where flowing water.

Preferably, the housing seat was installed with the possibility of rotation around an axis parallel to the direction of movement of the valve element. Due to this, the valve seat is not only retained in the inner cavity in a fixed place, but also keeps coaxial position relative to the valve element. Therefore, if the body of the saddle is moved, the new alignment valve element is not required.

The second end of the channel preferably is surrounded by a seal. Therefore, the inflowing water is reliably separated from the flowing water. Installation requires less than precision fitting body seat and the valve body.

It is advisable that the internal cavity was axisymmetric along the way, which moves the second end of the channel. In this case, the second end of the channel always remains at the same distance, preferably even in contact with the wall of the internal cavity. In particular, if the seal is ensured that it always remains in its place. This simplifies the moving body of the saddle.

The internal cavity may be at least in the area in which raspolozivost sphere, that allows you a simple way to get a good seal.

The first and the second position is preferably offset relative to each other by 180o. This corresponds to the usual traditional design of the valve of the radiator, in which the inlet coupling and the outlet coupling element are opposite to each other. It also simplifies the installation of the required angular position of the body of the saddle, as when turning 180othe path will be the same in both directions.

It is advisable that the inlet and outlet openings have axes set at the same angle to the direction of movement of the valve element. This ensures that the second end of the channel in any position of the seat with its rotation will always be in tight contact with the inner wall of the cavity in the region of the holes.

The angle preferably is in the range from 40 to 50o. This is expedient in particular when the inlet connecting element located on the side, and the outlet of the connecting element on the bottom of the valve body. In this case, at an angle of approximately 45oboth holes get about equal to the transverse napravlyauschie ring, which is sent in the body of the valve or connected with it inserted. Guide ring ensures that the body of the saddle, which, in the area of the second end of the channel adjacent to the valve body on one side only, always retains the correct position, whereby the valve element can interact with the valve seat adequately.

Guide ring preferably has a surface for application of torque. Since the guide ring is supported at its perimeter is almost uniformly, the application thereto of torque gives the best opportunity to turn the body of the saddle evenly and avoiding the one-sided loads.

The surface for the application of torque preferably interacts with externally accessible actuating device. In this case, the guide ring is not necessary output. You can use the actuating device, which is already available in many valves, for example, to pre-adjust the flow.

Guide ring can be connected with the valve seat through the retaining brackets, which extend in the circumferential direction of the maximum is the same as the length ol the COP, there is enough space to flow from the internal cavity through the opening, not combined with the second end of the channel. The body of the seat itself does not prevent the flow of water through the valve.

Preferably, one holding bracket was located in the circumferential direction in the area of the second end of the channel. In this case, because of the inflowing water experiencing the greatest forces that render the holding bracket required resistance, and the second end of the channel can be maintained in contact with the wall of the internal cavity.

Preferably, the two retaining bracket were shifted relative to each other by 180o. This gives two advantages. First, on the side opposite the inflowing water is always provided with sufficient bearing housing seat in the valve body. Secondly, the two retaining bracket with correspondingly large gaps between them represent only a relatively small resistance to current through the valve of the water.

Hereinafter the invention is described in more detail by the example of the preferred variants of its implementation with reference to the drawings, in which: Fig.1 schematically depicts a cross section of the valve of the radiator, the radiator, comprising a housing 2 of the valve with the inlet of the connecting element 3 and the outlet of the connecting element 4. The concept of "inlet" and "outlet" are used for two connecting elements only in order to distinguish them. As will be shown below, not necessarily in that water (or other liquid) is always entered through the inlet connecting element 3 and out through the outlet of the connecting element 4.

In the housing 2 of the valve has a cavity 5, soamsawali through the inlet 6 with the inlet connecting element 3 and through the outlet 7 from the outlet of the connecting element 4.

In the inner cavity 5 has a housing 8 of the saddle, in which there is a channel 9, which has a first end 10 and second end 11. The first end 10 of the channel 9 forms, as best seen in Fig.2, the seat 12 of the valve, with which cooperates a valve element 13, which is known and therefore not described in detail by way moves the spindle 14 of the valve is moved, in turn, pin 15 passing through the seal 16. Depicted schematically spring 17 presses the valve element 13 of the seat 12.

The second end 11 of the channel 9 is surrounded by a sealing ring, which in the housing 8 of the saddle is made kanavillil ring 22 two retaining brackets 20, 21. Guide ring 22, as seen in Fig.1 and 2, is directed in box 23, screwed into the body 2 of the valve. For clarity in Fig.1 and 2 between the guide ring 22 and the insert 23 depicts a small gap. This gap is usually still less than shown in the figure, so that the housing 8 of the seat can be rotated relative to the insert 23 and thereby relative to the valve body without changing its position in the housing 2 of the valve.

One retaining bracket 20 (as viewed in the circumferential direction) is fixed on the seat 12 of the valve where comes the second end 11 of the channel 9. The second retaining bracket 21 is displaced relative to the first 180o.

On the guide ring 22 has a surface 24 for the application of torque, for example, in the form of a slot. This surface 24 for the application of torque may be accompanied by an appropriate surface for the application of torque, which is located in the guide ring 22, which is displaced by an angle different from 180o. In any case, the surface 24 for the application of torque is in the area of one of the retaining brackets 20, 21. Thanks to this guide ring 22 and the actuator can be coupled to each other only in a specific direction, the maximum is the same as the length of the intervals between them in the circumferential direction, however, as a rule, is substantially less than the length of these intervals. Thus, the housing 8 of the saddle is very open and it has little resistance to the flow of water (or other liquid).

For moving the housing 8 of the seat in the housing 2 in box 23 is installed outside actuating element 25. Actuating element 25 has a protruding from the insert 23 working surface 26 on which the installer can act either by hand or by a tool to rotate the housing 8 of the seat in the housing 2 of the valve shown in Fig.1 position in which the second end 11 of the channel 9 is aligned with the inlet opening 6, 180o, resulting in the second end 11 is combined with the outlet 7.

The shape of the bottom of the inner cavity 5 corresponds to the surface of the ball, i.e., this surface is made spherical. Thus, it is axisymmetric, so the housing 8 of the valve, specifically surrounding the second end 11 of the channel 9 of the sealing surface 27 regardless of the angular position of the housing 8 of the saddle relative to the housing 2 of the valve is held in contact with the wall of the internal cavity 5. Due to the spherical form is Ino is improved by the sealing ring 18. As in any position of rotation of the housing 8 of the saddle relative to the housing 2 of the valve between them will not be increased clearance, no danger of falling out of the sealing ring 18 from its groove 19. In principle can be used almost any axisymmetric form.

The retention brackets 20, 21 may be additionally provided with projections 28, which may serve as guides for the valve element 13. As a result, always ensures the accurate positioning of the valve element 13 relative to the seat 12 of the valve regardless of the angular position of the housing 8 of the saddle relative to the housing 2 of the valve.

As can be seen in particular in Fig.1 and 2, the inlet 6 and outlet 7 is inclined by approximately 45orelative to the vertical, i.e., relative to the direction of movement of valve element 13. The intake connecting member 3 is positioned horizontally, and the outlet of the connecting element 4 vertically. Due to the orientation of the inlet 6 and outlet 7 they both have essentially the same cross-section.
