Description
Technical field
The utility model relates to a kind of reduction valve technical field, particularly relates to a kind of automatically controlled CNG 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.
Model utility content
For solving the CNG reduction valve problem that significantly thereby temperature declines working life of reducing reduction valve during step-down, the utility model provides a kind of automatically controlled CNG gas pressure reducer.
The purpose of this utility model is achieved through the following technical solutions:
Automatically controlled CNG gas pressure reducer, comprise chamber A and chamber B, suction port one end is arranged on chamber A, the suction port the other end is provided with solenoid valve, and chamber A lower end is provided with bottom, and chamber B upper end is provided with top cover, air outlet is arranged 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 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 utility model 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 utility model is provided with water intake and water outlet on reduction valve, the cooling system of the utility model and motor is connected, 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.
