Problems solved by technology

Therefore, the pressure regulator made of metal is not suitable for use in the biogas field, and even if it is barely used, the service life is very short
Third, the price of the existing commercially available pressure regulators of various specifications is relatively expensive, which is not acceptable to farmers who use biogas
In short, the existing commercially available pressure regulators of various specifications are not designed and manufactured according to the characteristics of biogas

Embodiment Construction

[0011] Such as figure 1 As shown, a biogas pressure regulator includes a plug cover 1, an upper casing 4, a lower casing 7, an air inlet nozzle 11 and an air outlet nozzle 12 arranged on the lower casing 7, and the inner casing of the upper casing is arranged There is a pressure regulating block 2, and a screw fit is arranged between the pressure regulating block 2 and the upper casing 4, so that the position of the pressure regulating block 2 can be adjusted. A rubber diaphragm 6 is clamped between the upper housing 4 and the lower housing 7, and the rubber diaphragm 6 is a rubber sandwich fabric film resistant to hydrogen sulfide corrosion, so that the rubber diaphragm 6 has enhanced aging resistance and elasticity. uniform. A tray 5 is arranged on the top of the rubber diaphragm 6 , and a spring 3 is arranged between the pressure regulating block 2 and the tray 5 , and the elastic force of the spring 3 can be adjusted by adjusting the position of the pressure regulating bl...

Abstract

The invention relates to a methane pressure regulator that includes block cover, up case body, down case body, pressure regulate block on the top in the up case body, rubber membrane between the up case body and the down case body. A tray is set on the rubber membrane. And a spring is set between the pressure regulate block and the tray. The tray is fixed on the top of the connecting bar through the rubber membrane. The bottom of the connecting bar connects to a valve pad through the valve mouth. The bottom of the case body has valve core supporting cover. The material of blocking cover, up case body, down case body, pressure regulating block, tray, connecting bar and the valve core supporting cover is ABS plastic. And the rubber membrane and the valve pad are made up of rubber material that can endure the cauterization of sulfureted hydrogen. The invention solves the cauterization problem and is easy to install.

Description

technical field [0001] The invention relates to a gas equipment, in particular to a biogas pressure regulator. Background technique [0002] The pressure regulator is an important device in the gas system. It is used to control the pressure condition of the gas system. The pressure regulator has the function of reducing and stabilizing the outlet pressure. Within the rated pressure and flow range, when the inlet pressure or outlet load changes , it can automatically adjust the opening and closing of the valve port, so that it is always stable within the set pressure range. [0003] The national standard (GB / T3606-2001) has been formulated for domestic biogas stoves, which stipulates that the rated pressure of the biogas in front of the stove is 800pa or 1600pa. In order to achieve this rated pressure, domestic manufacturers are required to develop various gas control valves (switches) that must use the opening size to achieve stable flow and stable pressure. Since the pres...
