The invention relates to a valve, particularly a valve of a radiator, comprising a housing having an inlet connection and outlet connection element between which the flow path is shut-off device with the valve element and the node is

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 must be connected to 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 no problem.

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 the clearance between the valve element and the seat becomes less than a certain value, the valve element instantly closes, resulting also instantly increases the pressure in the schematics creates unpleasant noises 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 also because in old buildings or installations, it is impossible to determine exactly what the pipeline is used to supply hot water, 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.

For valve radiator mentioned type, this task is solved in that the node saddle valve has two outlet valve seats, one of which corresponds to the inlet and the other outlet connecting element, and a valve element and node of the valve seats installed with the possibility of rearrangements relative to each other so that the valve element can interact by choice or whether he inlet connector with tubing which is supplied to the liquid used in the heating system and the outlet of the connecting element with the pipeline through which the fluid is drained. If the valve of the radiator is not installed properly, then you just need to change the positioning of the valve element relative to the corresponding outlet valve seats, so that you can ensure that the valve element will always be objectsa flow passing through the valve seat with which the valve element communicates. In this case, is usually guaranteed the absence of noise, causing damage and caused by hydraulic shock. Thus, the path of fluid flow in the valve of the radiator can be changed.

The valve member is preferably in the case of a valve element, and the node of the valve seats is contrary, and at least one of these two parts, comprising a valve body element and contrary, installed in the housing can be rotated. By turning any of these parts can be positioned either valve element relative to the inflowing fluid or flowing fluid relative to the valve element. The rotary movement is implemented laid the.

Installed with the possibility of turning the item can be sealed relative to the housing of the peripheral seal. Peripheral seal reliably ensures integrity, including when a rotary motion.

Installed with the possibility of turning the item preferably is held in the housing device with a spring retaining ring. The device with a spring retaining ring protects the specified item from axial displacement, however, allows its rotary movement.

Installed with the possibility of turning the item is preferably bonded to the housing in each of its two possible operating positions. So the installer can easily determine when the rotation reaches the correct position. Using the locking device, this position can then be fixed. If necessary, the valve element can accurately be positioned relative to the valve seats.

According to a preferred variant implementation, contrary made in the form of a pipe with two side nozzles arranged relative to each other with axial and angular displacements, and depending on the position of the pipe when turning either one nozzle is combined with a hole of the first pipe is closed housing. This version can be relatively simply obtained the required flow path in the valve of the radiator without having to move the actual valve seats. If one of the nozzles combined with the opening of the valve seats, fluid heating system can flow through the pipe and to flow around the valve member through the valve seat. Drainage of liquid through the outlet and around the outside of the pipe. In another position when the rotating pipe flow valve element through the valve seat, and the fluid flows around the outside of the pipe and is discharged through an outlet in the other pipe and through the inner cavity of the tube. This valve radiator can be easily implemented with the appropriate contracual, which can also be made from plastic.

Contrary preferably has an externally accessible surface for the application of torque. Through this surface, you can apply the necessary torque to contrapose for rotation in the housing. The surface for the application of torque may be formed, for example, a hexagon socket. Thus, it is possible to perform a permutation of the valve even t is Rita removable cover. This cover can be screwed to the outside of the case. On the one hand, it protects the surface for the application of torque from pollution, and on the other hand, can be used to seal the valve of the radiator on the outside.

In another embodiment, the valve element is located in the valve housing of the eccentric element, and the node saddle valve has two valve seats. By turning the casing valve element to move the valve element in the choice either to one or to the other valve seat.

Below the invention is described in more detail by the example of the preferred embodiments with reference to the drawings, in which: Fig.1 depicts a first embodiment of the valve of the radiator with the normal direction of flow of the stream, Fig. 2 - valve radiator with the opposite direction of flow of the stream, Fig.3 - kontrabas a perspective view and Fig.4 is a second embodiment of the valve of the radiator.

In Fig. 1 shows a valve 1 radiator, comprising a housing 2 having an inlet connecting element 3 and the outlet of the connecting element 4. Arrows 5 indicate the flow path of the fluid used in the heating system the capacity element 6, interacting with the seat 7 of the valve. The valve element 6 can be moved by the pusher 8 of the valve seat 7, as shown only schematically. A spring 9 which presses the valve element 6 from the seat 7 without any external forces.

The direction of flow, as shown in Fig. 1, characterizes the "normal" course, in which the valve element 6 is flown by the flow through the seat 7 of the valve. Therefore, either when opening or closing the valve does not occur any problems. When the movement of the valve element 6 to the saddle 7 is a gradual throttling of the flow of water due to the fact that the clearance between the valve element 6 and a seat 7 is continuously decreasing. Moving the valve element 6 is carried out exclusively by the pusher 8.

Problems at closing of the valve 1 when the direction of the pass-through fluid flow changes. This situation may occur, for example, if you incorrectly install the valve, namely, or due to the fact that the installer did not pay attention to the direction of leakage flow through the valve, or due to the fact that he just didn't know what the pipeline is used to supply, and which drain the heating system. In this text the closing of the gate valve element 6 is lowered to the saddle 7 instantly, as soon as the distance between them is less than a certain value. This is a quick lowering causes an immediate stop of water flow, resulting in the so-called hydraulic shock, which creates significant noise. In addition, pressure surges associated with hydraulic shock can cause serious damage in the heating system.

To avoid this danger, the valve 1 of the radiator is located in the housing 2 detail hereinafter contracual 10. Contrary depicted in Fig.3 is a perspective view, located in the hole 11, which forms a continuation of the inlet openings of the connecting element 3. Contrary 10 made in the form of a pipe 12 with the first flange 13 and the second flange 14 mounted in the housing 2 with the seal by the sealing rings 15, 16. Contrary 10 has two nozzles 17, 18 adjacent to the inner wall of the hole 11 and compacted with regard to them. The pipes 17, 18 are located on the pipe 12 with an axial offset relative to each other and are connected to the internal cavity 19 of the pipe. The nozzles are arranged with an angular offset relative to each other, for example, on the 90o. Contrary 10 is installed in the housing 2 with the possibility of Et 21 for application of torque, for example, the inner hexagon. Using this surface 21, which is accessible from the outside, contrary 10 can be rotated in the housing 2. The surface for the application of torque can be closed by a cap 22 screwed on the casing, if necessary, install seal (not shown).

Thanks to contrapose 10 valve element 6 is always flown the flow through the seat 7 of the valve. The "normal" flow, which is shown in Fig.1, the fluid heating system is supplied from the inlet of the connecting element 3 through the internal cavity 19 of the pipe 12 and the pipe 17 to the seat 7 of the valve and flows around the valve element 6, passing through the saddle 7. Then the fluid flowing through the clearance between the valve element 6 and seat 7, may, through the outlet opening 23 (Fig.2) adjacent to the valve seat, to enter again into the hole 11, to place it around the outside of the pipe 12 and then to act in the discharge of the connecting element 4. This path is shown by arrows 5, represented by a double line.

In Fig. 2 shows the situation with the opposite direction of the flow of fluid through the housing 2, i.e., when used in the heating system the liquid enters the outlet of the connecting element 4, and exits the single lines, could flow around the valve element 6 through the valve seat, contrary 10 rotate in the hole 11 on the 90o. This pipe 17 is out of contact with the seat 7 of the valve and closes the inner wall of the hole 11, and the pipe 18 is combined his hole with the outlet 23. Thus, the fluid heating system wraps around the pipe 12 and passes through the seat 7 of the valve to the valve element 6. Then the liquid through the outlet 23 and the pipe 18 enters into the internal cavity 19 of the pipe 12 and flows into the cavity to the inlet of the connecting element 3.

Therefore, the direction of fluid flow in the valve 1 of the radiator can be changed in a simple way by turning contracual. In this embodiment, the design requires only one seat 7 of the valve, which communicates with the valve element 6 regardless of the direction of the flow in the valve.

Thus, contrary 10 forms two output valve seats, namely, first, the nozzle 17, which may be mounted coaxially with the seat 7 of the valve, and secondly, the cavity 29 is located between the outer side of the pipe 12 and the inner wall of the bore 11.

In Fig.4 shows a modified construction in which d is orpus 25 with two seats 7a, 7b of the valve. The valve element 6 is located in the housing 26 of the valve element, which can be rotated relative to the housing 25 about the axis 27. The valve element 6 is eccentric relative to the axis 27, as well as the saddle 7a, 7b. Therefore, when the rotation body 26 of the valve element 180oaround the axis 27 of the valve element 6 out of contact with the saddle 7a and comes in contact with the saddle 7b. In the form shown in Fig. 4 the position of the body 26 of the valve element, the valve element 6 is installed to ensure that the leakage flow from the inlet connecting element 3 to the exhaust connecting element 4. In this case, the valve element 6 is flown by the fluid passing through the saddle 7a.

In another, not shown in the drawings, the position of the body 26 of the valve element when the valve element 6 interacts with the saddle 7b, it becomes possible to reverse the direction of flow, i.e., the fluid heating system may leak from the exhaust of the connecting element to the inlet of the connecting element 3. In this case, the valve element 6 is flown fluid through the seat 7b.

The housing 26 of the valve element is held in the housing 25 of the spring retaining ring 20 and compacted uplatne the th stream can even when it is already installed. In the variant according to Fig.4 torque can be applied through the connecting pipe 28 in which is located a plunger 8.

There is also a variant (not shown), in which contrary 10 in the housing 2 or the housing 26 of the valve element in the housing 25 can be fixed only in certain positions. In this embodiment, may be provided, for example, the retaining elements, possibly in the form of spring-loaded balls which enter into corresponding recesses on the peripheral surface of contracual 10 or housing 26 of the valve element. Additionally or alternatively may be provided by marking on the outside indicating the "correct" position of the rotary parts.
