Description

one

The invention relates to the regulation of the temperature of a water-type heating system with single-line wiring, carried out using shut-off and control valves.

The one-way radiator heating system is known to have a number of advantages over a two-pipe heating system with a supply and a branch line. The main one is the reduction in the number of pipes and their joining points, which simplifies the assembly and operation of the {1J.

However, a single-line heating system must have temperature control devices, as well as shut-off valves for connecting radiators, otherwise dismantling will require water to drain from the entire system.

Temperature controllers are known for a central single-flow system, comprising an overflow valve mounted on one of the radiator bushings and connected to the other radiator bush by a pipe connected to line 2.

However, the use of known devices does not eliminate the disadvantages of a single-line heating system both during installation and operation.

In order to provide ease of operation in the proposed temperature controller, the bypass valve is mounted on the upper radiator sleeve, and the lower sleeve is provided with a bypass valve. which are connected to the main line by inlet and outlet fittings and to a radiator. A regulating element is installed in the shunt valve housing, which distributes the flow of hot and cold water passing through the radiator.

FIG. 1 shows a longitudinal section of the valves installed on the radiator; in fig. 2 shows a possible connection between the lower valve and the upper valve.

The radiator 1 is connected to the threaded part of the bypass valve b and the bypass valve body 7 by means of threaded bushings 2 and 3 and cap nuts with nipples 4 and 5. The latter are connected between each other by a tube 8. In the body 7 of the shunting valve there are additionally two fittings 9 and 10 for supplying hot water and for discharging cooled water, respectively. In the upper part of the housing there is also a branch II for connecting it to the tube 8.

Both fittings 9 and 10 communicate with each other by a ring channel 12, and the turn is gray, and sleeve 3 is connected to the radiator.

In the front part of the valve body, a bore 14 is made for a stopper, and then a smooth section that contacts with the seal and then goes into the thread 15. A regulating element 16 is placed at the end of the bypass valve body 7. At one end it has a seal assembly 17 and an annular groove 18 to install an O-ring 19 in it. The element 16 is named after him (a threaded section 20, screwed with a thread of the housing 15. And at the other end of the stem, a valve 21 of conical shape is sealed, which is sealed to the seat 13 of the housing 7 as metal-to-metal. Between the threaded section 20 and the plate 21, a smaller diameter section 22 is made, the length of which is chosen such that when the plate 21 is closed between fittings 9 and 10, there is an open passage for the flow of hot water ..

Seat 24 is formed in the housing 6 of the relief valve 23, which interacts when the stem 25 is moved with the valve 26 fungus. The stem 25 is screwed with a thread into a sleeve 27 fixed in the housing 6. In the front part of the valve 26 there is a cylindrical section 28, which is closed in the process allows throttling of the flow of water, thereby regulating the temperature. The valve stem is rotated by a flywheel 29 which has locking devices.

The valve 23 is connected to the lower shunt valve by means of a threaded joint 30, which has a compensating assembly in the case that the length of the tube 8 between the radiator sleeves 2 and 3 is selected. The lower shunting valve also has a protective sleeve 31.

FIG. 2 shows a modified connection of the lower shunting valve to the tube 8, (bypass valve 23 is of the detachable type and close to the ceiling) of the upper valve and consists of a union nut 32 and sealing rubber ring 33. Such a joint design allows the position of the lower valve to change when the pipeline position changes.
