Description
Technical field
The utility model relates to valve technology, is specifically related to a kind of self-forced type pressure and temp combination variable valve.
Background technology
The temperature automatic adjustment that self force type temperature regulating valve is widely used in heating, air-conditioning, domestic hot-water, and the temperature automatic adjustment of special operation condition, such as production engineerings such as chemical industry, weaving, pharmacy. Self force type temperature regulating valve does not need external energy just can control the flow of steam in water back, hot water or heat oil, the temperature of the various heat exchanger of control and thermostat medium automatically. Self force type temperature regulating valve structure is simple, reliable operation, it may also be useful to easy to maintenance. But the single self force type temperature regulating valve, pressure reduction variable valve and the self-forced type Liquid level adjusting valve that generally use at present and safety valve and reducing valve, the self-forced type pressure and temp combination still rare report of variable valve.
Practical novel content
The utility model is intended to provide a kind of self-forced type pressure and temp combination variable valve.
Self-forced type pressure and temp combination variable valve in this scheme, comprise temperature pack assembly, pressure pilot valve, temperature pilot valve, main valve and room, main film chamber, temperature pack assembly comprises kapillary, kapillary is connected with temperature pilot valve, temperature pilot valve is drawn the first branch road and the 2nd branch road respectively, first branch road and main film chamber, 2nd branch road is connected with pressure pilot valve, pressure pilot valve is connected with main valve, room, main film chamber is connected with main valve, steam inlet tube is connected to the side that main valve is connected with pressure pilot valve, steam goes out pipe and is connected to the main valve back of the body to the side of pressure pilot valve, the 3rd branch road drawn by pressure pilot valve, 3rd branch road is connected to steam and goes out on pipe.
Principle of work of the present utility model is as follows: before startup, and normal position is that main valve is closed, and pressure and temperature pilot valve is opened. During startup, the steam entered is first through excess pressure pilot valve, then enters temperature pilot valve by pressure pilot valve, and the outlet through throttle orifice. When controlled plant is in heated condition, being greater than the flow through throttle orifice through the steam flow of excess pressure pilot valve and temperature pilot valve, the control pressure in room, main film chamber increases, and main valve is opened. Owing to pressure pilot valve is connected with temperature pilot valve serial connection, therefore pressure pilot valve provides vapour source all the time by temperature pilot valve of a constant pressure.
At pre-heating stage, steam enters room, main film chamber, and main valve plug is by jack-up, thus steam flows through main valve enters by control object. When being reached by the temperature of the warm pack assembly in control object or close to design temperature, the kapillary in temperature pack assembly feeds back to temperature pilot valve, makes temperature pilot valve close or be in close to closing condition. Owing to controlled plant is in heat exchange state all the time, therefore temperature pilot valve can be in adjustment state always. When not needing steam, temperature pilot valve and main valve are closed.
The self-forced type pressure and temp combination variable valve induction of this scheme is sensitive, and reliable operation, can regulate the temperature of controlled plant at any time automatically.
Further, in order to realize automatically regulating the pressure compensating pressure-sensitive diaphragm side, this scheme is also provided with pressure and regulates assembly, and pressure regulates assembly to comprise the pressure-sensitive diaphragm being positioned at pressure pilot valve side, the regulating spring being connected with pressure-sensitive diaphragm and the pressure regulator panel being arranged on regulating spring.
Further, temperature pack assembly comprises temperature bag main body, is provided with in one end of temperature bag main body and draws long pipe, draws long pipe and dismountable is in charge of end to end and become by multiple, and each is in charge of the interior hole that all had, and the cavity crossing Kong Yuwen bag main body communicates, and kapillary crosses hole through described. The periphery being in charge of at each is equipped with thread segment, is connected with bolt wherein on a thread segment, and bolt is externally connected with the joint for the ring-type installed with analyte. Said structure designs, when needing the degree of depth regulating temperature bag main body insertion analyte according to analyte difference, as long as pulling down or install being in charge of of desired number, then bolt on the place of being in charge of specified connects, bolt connects joint again, is installed together by joint and analyte.
