Abstract

The invention discloses a pressure control valve which comprises an air inlet, a gasket, a bellows, a valve body, a cone valve and an air outlet. Two ends of the valve body are provided with the air inlet and the air outlet respectively, the bellows is arranged in the valve body, the gasket is arranged between the bellows and the air inlet, and the cone valve is arranged between the bellows and the air outlet. The cone valve at the position of the air inlet is controlled through the bellows to achieve pressure control, a refrigerant cannot be leaked easily, and the pressure control valve is simple in structure and works stably and reliably.

Description

A kind of pressure regulator valve
Technical field
The present invention relates to a kind of pressure regulator valve.
Background technique
In order to maintain the normal operation of refrigeration system, usually adopt pressure or the temperature of controlling refrigeration system.Because refrigeration agent temperature and pressure under saturation state has relation one to one, therefore can adopt the method for pilot pressure to guarantee suitable evaporator temperature, to prevent that evaporator pressure from causing evaporimeter frosting lower than specified value, once and vaporizer frosting, can have a strong impact on the heat-transfer capability of vaporizer, make temperature in system can not fall, thereby affect the normal operation of whole refrigeration system.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, provides a kind of simple in structure, the reliable pressure regulator valve of working stability.
Technological scheme: in order to realize above purpose, a kind of pressure regulator valve of the present invention, it comprises suction port, packing ring, bellows, valve body, cone valve and air outlet, the two ends of described valve body are respectively equipped with suction port and air outlet, and the inside of valve body is provided with bellows, in the middle of described bellows and suction port, place is provided with packing ring, and in the middle of bellows and air outlet, place is provided with cone valve.
Described valve body is solid of rotation.
Described cone valve adopts the mode be fixedly connected with fastening with bellows.
Beneficial effect: the cone valve that pressure regulator valve provided by the invention is controlled the suction port place by bellows is realized the control of pressure, is difficult for revealing refrigeration agent, and simple in structure, working stability is reliable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
Be illustrated in figure 1 structural representation of the present invention, it comprises suction port 1, packing ring 2, bellows 3, valve body 4, cone valve 5 and air outlet 6.
The two ends of described valve body 4 are respectively equipped with suction port 1 and air outlet 6, and the inside of valve body 4 is provided with bellows 3, and in the middle of described bellows 3 and suction port 1, place is provided with packing ring 2, and in the middle of bellows 3 and air outlet 6, place is provided with cone valve 5.
Described valve body 4 is solid of rotation.
When evaporating pressure, during higher than setting value, bellows 3 is compressed, because cone valve 5 adopts the mode be fixedly connected with fastening with bellows 3, thereby makes cone valve 5 be moved to the left, and air outlet 6 apertures increase, and make refrigerant flow increase, and evaporator temperature descends.When temperature drops to certain value, evaporating pressure is during lower than setting value, bellows 3 elongations, because cone valve 5 adopts the mode be fixedly connected with fastening with bellows 3, thereby make cone valve 5 move right, air outlet 6 apertures reduce, make refrigerant flow reduce, evaporator pressure can increase again.Air outlet 6 is constantly being opened and is closing, so repeatedly, and to guarantee that evaporating pressure is in suitable scope.This pressure regulator valve is controlled the cone valve 5 at 6 places, air outlet by bellows 3, realize the control of pressure, be difficult for revealing refrigeration agent, and simple in structure, working stability is reliable
Above-described embodiment is only explanation technical conceive 1 of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention enforcement according to this, can not limit the scope of the invention with this.All equivalents that Spirit Essence has been done according to the present invention or modification, within all should being encompassed in protection scope of the present invention.
