Abstract
Disclosed is a self-power temperature regulator capable of feeding back pressure. The utility model is additionally provided with a pressure feedback system based on a corrugated tube self power temperature regulator, which overcomes the adverse effect from the unbalance force of an adjustable valve to an actuating mechanism and achieve favorable performance of regulation. The function of regulation is free from the media pressure limitation of a valve body that is flown across, and the utility model has the advantages of simple structure, reasonable design, small size and reliable performance, suitable to achieve automatic temperature control in occasions, such as heat supplying, air conditioning, etc.
Description
The utility model belongs to temperature-adjusting device, a kind of thermostat that is applicable to fields such as heat supply, air-conditioning.
Existing self-powering type duct thermostat has two kinds of diaphragm type and bellow types.Because the elastic element of film self-powering type duct thermostat is fragile, can not use for a long time.When using bellows self-powering type duct thermostat, the medium of the import and export of flowing through acts on the pressure imbalance on the modulating valve, has had influence on the regulatory function of regulator, and particularly this regulator has just lost regulatory function under heavy caliber High Pressure Difference situation.So, when using this regulator,, have to adopt reduction valve to reduce the modulating valve inlet pressure in order to reduce unbalanced force, caused effective loss of energy so again, and installed and used very inconvenient.
The purpose of this utility model is invented a kind of temp regulating function valve body of not flowed through and is imported and exported pressure medium and influence, regulate be active in one's movements, novel self-powering type duct thermostat that regulating effect is good.
The utility model is bellows self-powering type duct thermostat to be improved become the self-powering type duct thermostat with pressure feedback ability.Bellows self-powering type duct thermostat is made up of thermometer bulb, PRESSURE PIPE, support, bellows, push rod, valve rod, valve body, flap etc., and the utility model is that the pressure feedback system is housed on valve rod.
Accompanying drawing 1 is an overall construction drawing of the present utility model.
Accompanying drawing 2 is a pressure feedback system construction drawing of the present utility model.
Be described in detail structure of the present utility model in conjunction with the accompanying drawings.
The pressure feedback system is made up of Seal cage (13), pressure feedback bellows (14), guide holder (17), upper cover plate (19), lower cover plate (21) etc.Seal cage (13) upper end links to each other with support (3), and Seal cage (13) lower end links to each other with valve body (16) by flange plate.The upper end driving fit of pressure feedback bellows (14) connects upper cover plate (19), and the lower end driving fit connects lower cover plate (21), the centre sleeve pipe (20) of packing into.The upper end of sleeve pipe (20) is by screw threads for fastening and seam or bonding tight, put into guide holder (17) from the lower end cover, the lower end of sleeve pipe (20) is associated in flap (15), sleeve pipe (20) cover that the pressure feedback bellows is housed is installed on the valve rod (4), with guide holder (17) and lower cover plate (21) valve body of packing into, and fasten by the flange plate of Seal cage (13) and the flange plate of valve body (16).Porose gap by sleeve pipe (20) communicates with Seal cage (13) on flap (15) bottom, and guide holder (17) is gone up the inner chamber UNICOM of porose outlet plenum and pressure feedback bellows (14) with valve body.
When using this regulator, when being transferred medium temperature to rise, by thermometer bulb (1) temperature is passed to temperature sensing agent (9), make its expansion, expansive force promotes push rod (7) by bellows (10), through valve rod (4) flap (15) is depressed, turn down the valve body import, the pressure medium trend of valve body import at this moment raises, and outlet pressure reduces, if it was just big originally to flow to the pressure medium of valve body import, had at this moment produced big pressure reduction between the import and export of valve body; The high-pressure medium of valve body inlet advances Seal cage (13) by the orifice flow that the flap bottom communicates with Seal cage (13) in this case, pressure action of medium is in the outside of pressure feedback bellows, because the valve outlet chamber communicates with the inner chamber of pressure feedback bellows (14), so the external pressure of pressure feedback bellows (14) is greater than chamber pressure.Utilize this pressure reduction by sleeve pipe (20) boosting flap on the direction identical like this, thereby overcome the adverse effect of modulating valve unbalanced force actuator with valve rod (4) active force.This regulating power with self-powering type duct thermostat of pressure feedback ability is just avoided having flowed through the influence of valve body pressure medium.
This design of Regulator is reasonable, simple in structure, volume minor adjustment precision height, and the do not flowed through influence of valve body pressure medium of regulatory function, applied range, reliable performance is used for heat supply, and occasions such as air-conditioning realize that automatic temperature-adjusting regulates.
