Abstract
The invention discloses a square gas pressure reducing valve. The square gas pressure reducing valve comprises a cavity A (301) and a cavity B (302), wherein an air inlet (1) is formed in the cavity A (301); the cavity A (301) and the cavity B (302) are controlled through an electromagnetic valve (6); a bottom cover (1001) is arranged at the lower end of the cavity A (301); a top cover (1002) is arranged above the cavity B (302); an air outlet (5) is formed in the cavity B (302); a spring control end (8) is arranged in the top cover (1002); a water inlet (2) is formed in the cavity A (301); a water outlet (7) is formed in the top cover (1002). The square gas pressure reducing valve has the advantage and beneficial effect that the service life of the pressure reducing valve can be prolonged due to the fact that the square gas pressure reducing valve is communicated with a cooling system of an engine, and hot water flows from the water inlet and can guarantee that the pressure reducing valve works for a long time at the temperature of about 50 DEG C.
Description
Technical field
The present invention relates to air valve device technical field, particularly a kind of square gas pressure reducer.
Background technique
Gas pressure reducer is a kind of special arrangement of automatic reduction working pressure of pipeline, and it can be reduced to the higher fluid pressure of pipeline before valve the required level of pipeline after valve.The structural type of reduction valve is a lot, by structural type, can be divided into diaphragm type, spring diaphragm type, piston type, Lever type and bellow type etc.Press valve seat number artificially single seated and double seat.Position difference by flap can be divided into positive interaction type and reaction-type.By medium, can be divided into nitrogen reduction valve, hydrogen reduction valve, oxygen pressure reducing valve etc.The basic role principle of reduction valve is, by valve inner flow passage, the local resistance of current is reduced to hydraulic pressure, and the scope that hydraulic pressure falls is by connecting the film of flap or the import and export differential water pressures of piston both sides regulates automatically.
Traditional CNG reduction valve only has simple decompression, and the significantly pressure drop of reduction valve causes the decline of temperature, thereby reduces the working life of reduction valve.
Summary of the invention
For solving the CNG reduction valve problem that significantly thereby temperature declines working life of reducing reduction valve during step-down, the invention provides a kind of square gas pressure reducer.
Object of the present invention is achieved through the following technical solutions:
Square gas pressure reducer, comprise chamber A and chamber B, suction port is arranged on chamber A, between chamber A and chamber, be provided with solenoid valve, chamber A lower end is provided with bottom, and chamber B top is provided with top cover, air outlet arranges on chamber B, in top cover, be provided with spring control end, it is upper that water intake is arranged on chamber A, and water outlet is established on top cover.
As further improvement, also comprise sealing gasket A, between described chamber A and described bottom, by sealing gasket A, be tightly connected, the effect of using sealing gasket A is in order to guarantee the perfect sealing of chamber A and bottom.
As further improvement, also comprise sealing gasket B, between described chamber B and described top cover, by sealing gasket B, be tightly connected, the effect of using sealing gasket B is in order to guarantee the perfect sealing of chamber B and top cover.
As further improvement, the operating voltage of described solenoid valve is 12V, and this solenoid valve need to be connected with car accumulator, and 12V can meet user demand.
As further improvement, described suction port is female thread structure, can be connected with suction tude is perfect.
Further, the material of described chamber A and described chamber B is that Kohlenstoffgehalt is the carbon steel of 0.3-0.5 %, and Kohlenstoffgehalt is the rigidity requirement that the carbon steel of 0.3-0.5 % can meet chamber.
In sum, advantage of the present invention and beneficial effect are:
Traditional CNG reduction valve only has simple decompression, and the significantly pressure drop of reduction valve causes the decline of temperature, thereby reduces the working life of reduction valve.The present invention is provided with water intake and water outlet on reduction valve, and the cooling system of the present invention and motor is connected, and hot water flows into from water intake, and hot water can guarantee reduction valve long-term work at the temperature of 50 degrees Celsius of left and right, can extend the working life of reduction valve.
