Description

The invention relates to a valve structure, in particular, to the shut-off and control valves of heat transfer and heat exchangers, mainly water and steam heating systems.

The purpose of the invention is to increase the operational capabilities of the device by completely disconnecting heating devices in one-pipe heating systems with one shut-off and regulating element.

FIG. 1 schematically shows the proposed regulating device, a general view; in fig. 2 shows section A-A in FIG. one.

The regulating device includes a housing 1 with four pipes: pipes 2 connecting the heating device, pipes 3 draining the coolant from the device, and pipes 4 and 5 connecting the device to the main pipeline. Nozzles 4 and 5 are located on the same axis. The housing 1 is eccentric with respect to coaxial nozzles 4 and 5 and has a boring nest 6 for a locking and regulating element made in the form of a triangular plug 7, which is installed in it to form a through channel 8. Lower edge 9 of plug 7 in combination with channel 8 coaxial nozzles 4 and 5 and a passage 10 of the nozzle 3 of the heat carrier discharge forms an ejector when the heater is switched on. The device is controlled by the rod 11 of the plug 7. The nut 12 serves to secure the plug in the nest 6. To ensure sealing, the plug in the gaps between the faces in the passage section for the heat carrier and also has a cylindrical ground surface in the upper and lower parts.

In the open position of the device, the coolant flows from the main pipeline (not shown) through nozzles 4 and 2 to the device, and

5 part of the coolant through channel 8 transits to subsequent heating devices or other heat exchangers. Through pipe 3 and passage 10 coolant

10 from the device enters through pipe 5 back into the main pipeline. In view of the ejeki: tiuyuschey properties of the device, as well as resistance to the passage of transiting coolant

15, the protruding part of the plug 7 provides an equal coefficient of flow of the coolant into the device. In addition, ejection enhances the efficiency of mixing transit and

20 reverse from the device flow coolant. When turning the stem 11 in a clockwise direction, the three-sided plug 7 simultaneously blocks the passage of the coolant to and from the device. The

25 most can be both the regulation of the amount of coolant supplied to the device, and its complete shutdown. Simultaneous smooth overlapping of passages to the device and from it creates particularly effective regulation conditions in steam systems, since in this case the regulation occurs mainly due to steam throttling during

it enters the device, which allows to minimize the thermal inertia of the device. A single control authority and the provision of a device of low thermal inertia of a heating device or heat exchanger gives the device the necessary qualities to use it in automating control and regulation systems.
