The invention relates to the construction, and particularly to a three-way valve for the connection used in one-pipe hot-water heating systems of buildings, appliances water heating different designs (convectors, radiators), which relates to the regulation of the heating degree of the heater, thermostat and enables both manual control and regulation in automatic mode.

Know the use of the three-way valve for controlling the flow of water in the heater. Three-way valve includes a housing with three nozzles, communicating with a Central cavity in which is located the valve is moved manually by rotation, thereby providing an overlap of the two nozzles, one of which is when one pipe floor heating system is connected to the input in a heating device, and the second to the bypass (bypass), which in turn, through the tee connects to the main pipe (intermediate riser) to divert water and to the output of the heating appliance. In this third pipe three-way valve connected to the main pipe from which water is served coolant (Skanavi A.N., Mach L.M., heating, Moscow, Publishing house ASV, 2008, str, RES).

In this known solution is carried out at three levels of regulation: the heating device is engaged on the maximum power (when fully blocked the bypass area and all the coolant passes through a heating device); included in average power (when fully open the bypass area and the entrance to the heater); off (when open the bypass section, and the entrance to the heater is blocked and all the coolant is directed into the bypass section). Smooth regulation of the heating degree of the heater of known three-way valve does not provide.

To ensure a smooth regulation of the heating degree of the heater used thermoclean (Skanavi A.N., Mach L.M., heating, Moscow, Publishing house ASV, 2008, str, RES).

Known three-way thermoclean, including the case with three nozzles, communicating with a Central cavity in which is located the valve is exposed to the outside of the housing stock used to move the spool cavity (Technical catalogue company Vesta trading (Vesta Trading), 2009, str).

The first and second nozzles are positioned opposite each other and are communicated with the cavity of the housing through openings in the partitions separating the cavity of the nozzle from the Central cavity of the housing where the valve. The third pipe is orthogonal to them on an axis protruding from the opposite from his side of the stem of the valve. The valve has the form of a Cup with holes in the walls, and when it moves it may completely or partially block the tertia in the cavity of the first and second nozzles, thus the exception of submission to the Central cavity of the body of liquid coolant through one of the nozzles, or changing the amount of incoming coolant from the nozzle, or by changing the number of outgoing fluid from the Central cavity of the body, resulting varies the amount of fluid exhaust from the third nozzle. The first pipe is connected to the feed pipe of the heat transfer medium (intermediate riser), and the second inlet of the heater. The third pipe is connected to the bypass section that is connected to the output of the heater and discharge of coolant (continued intermediate riser).

For regulating the degree of heating of the heater manually, use the cap that is secured on the threaded contact with the bottom with the end of the rod, and when the screwing or unscrewing of the cap moves the spool.

For automatic regulation of the heating degree of the heater used control valve elements, which are made in the form of thermostatic heads known structures (Technical catalogue company Vesta trading (Vesta Trading), 2009, str-351), which are the axial actuator to move the valve. thermostatic head is fixed with the possibility of interaction is with the rod for moving the valve, providing automatic regulation of heating degree of the heater. Can be used with different functions thermostatic head, axial drives of other designs, including a plug to an external controller, which also allows you to provide for the regulation of heating degree of the heater or heating degree several heating devices.

Known three-way thermoclean in the manufacture requires fitting the outer cylindrical surface of the spool and the cylindrical surface of the Central cavity of the housing which carries the outer cylindrical surface of the spool. This makes the design of the three-way thermoclean complex, reduces the reliability of the three-way thermoclean in conditions of continuous operation due to deposits in the body, preventing the movement of the spool, so that the drive force of the control valve element may be sufficient to move the spool. In addition, the housing of the known three-way thermocline may not be made of steel with a smooth pipes for the purpose of connecting with the plug-in pipe welding because welding heats the body, it can be deformed, which leads to the release of thermoclean down, because the deformation results in the jamming of the valve.

More reliable design thermostatic valve comprising a housing with inlet and outlet nozzles, valve pipe, which has a spring-loaded rod on the end of which is fixed valve plate having an opportunity when moving rod can be connected to a seat on the partition between the cavities of the input and output sockets, connecting through the hole in the centre of the indicated seat. The second end of the rod is led outwards and are similar to the above can interact with the regulatory cap or with a thermal head to control the position of the valve stem, and thus throughput of the valve, allowing the adjustment of the heating degree of the heater. Such two-way thermostatic valves can be direct, when the inlet and outlet are on the same axis, or the angle which the axis of the inlet and outlet nozzles intersect at right angles (Technical catalogue company Vesta trading (Vesta Trading), 2009, str-340).

This known valve allows fine adjustment of the heating degree of the heater and its throttling - off area between the valve plate and seat allows for some deviation of alignment between the seat and the valve plate due to the fact that the valve plate has some mobility fixed the I on the rod, as well as the elastic element. The case is similar to the valve in its manufacture of steel can be attached to the steel pipe by welding, provided the minimum variation in adjustment between products in the same series that performs the same tuning operation when entering the heating system in operation.

However, when using this valve when connecting the heater in one-pipe heating system it is necessary to use additional tees for the formation of the bypass section, which complicates the Assembly process and extends the range of the used fittings in contrast to the situation of use of the three-way valve. Similarly, in the case of installation in a device known two-way valve it is necessary to form the bypass site or installation of the tee, or otherwise perform an orthogonal removal from the pipe, which in any case is simple and does not allow you to use special equipment for welding along the line of contact between two paired ends of the pipes. Reliability regulation is ensured not only by the design of the shut-off area, but the selection square poperchenogo section holes in the saddle, which correlated with more smaller squares cross-sections underwater and outlet pipes connected is respectively to the input and output sockets.

The technical result consists in the expansion of the means for continuous adjustment of the heating degree of the heater, allowing you to connect it to the single-pipe heating system with the formation of the bypass section and which are reliable in operation, and at the stage of commissioning in ensuring the accuracy of adjustment with minimal variation in adjustment between products of the same series.

This technical result is achieved by the three-way valve to connect the water heating device that includes a housing with inlet, outlet, bypass valve and nozzles, as well as controlled valve unit with the sleeve, shaft and valve plate.

Inlet and outlet of the housing are located on the same axis and separated by a solid partition, and an outlet pipe axis is at right angles to the axis of the inlet and outlet fittings and communicates with the cavity input socket.

The valve tube axis is perpendicular to the plane of the axes of the inlet, outlet and outlet nozzles, and its cavity is communicated via located on the axis of this cavity is a hole with a cavity inlet pipe, and a through channel with a cavity of the outlet pipe.

On the surface of the inlet pipe inside the cavity of the valve pipe around the hole in the bands of the b input tube is a valve seat for landing valve plates.

Rod controlled valve unit installed in the sleeve with the possibility of reciprocation with a protrusion at one end with one side of the sleeve and the protrusion of the second end on the other side, which is fixed to the valve plate, and a spring-loaded rod in the sleeve in the direction of pushing the first end of the sleeve.

Bush managed manifold rigidly fixed to the valve inlet housing with the possibility of contact of the valve plate with the valve seat when moving rod into the housing and located outside the area of the outer thread for fixing the control valve element, the minimum cross-sectional area of the channel, and the cross-sectional area of the holes, connecting the discharge pipe with the cavity input socket, smaller cross-sectional area of the holes, connecting the input cavity of the pipe with the valve cavity of the socket.

The difference between the three-way valve to connect the water heating device made in accordance with the present invention, from the well-known three-way valve is run corps and elements controlled valve block.

Case in a particular embodiment of the invention for connection of inlet, outlet and outlet nozzles welded can is t be made of steel. Thus the outer and inner surface of the inlet, outlet and outlet manifolds are smooth.

The case in the particular case execution can be provided for a branch pipe, which axis is at right angles to the axis of the input and output sockets on the opposite from the main outlet pipe of the tank, and also communicates with the cavity input socket and plugged the tube, the minimum cross-sectional area outlet channel, and the cross-sectional area of the holes, connecting the outlet sleeve with a cavity inlet pipe, and the cross-sectional area of the holes, connecting the additional outlet valve with cavity input socket, smaller cross-sectional area of the holes, connecting the input cavity of the pipe with the valve cavity of the socket.

As specified in the General case, and in these cases the invention, the managing Director of valve element can be made in the form of a cap attached with bottom contact with the first end of the rod or in the form of thermostatic head fixed with the opportunity to interact with the first end of the stem it of the pressure element is controlled solid or liquid sensitive element.

The valve plate can be performed with calcev the second groove, where this is annular sealing element for coupling with the valve seat.
