The utility model relates to the technical field of fuel gas pressure stabilizing valves, in particular to a pressure stabilizing diaphragm for a fuel gas pressure stabilizing valve.
Background
The pressure stabilizing diaphragm is mainly used as a part for regulating the pressure of gas in the gas control valve, and plays roles of pressure sensing and sealing. The existing pressure stabilizing diaphragm has the following defects: 1. in the assembly process of the diaphragm, the edge is pressed and deformed, so that the perception of the pressure of the diaphragm is affected; 2. the diaphragm and the valve core are connected in such a way that the valve core passes through the diaphragm and then is fixed through the clamp spring, so that leakage points and the problem of air leakage exist.
Disclosure of Invention
The utility model aims to provide a pressure stabilizing diaphragm for a fuel gas pressure stabilizing valve, which solves more than one problem in the background technology.
In order to achieve the above purpose, the present utility model adopts the following scheme: the utility model provides a steady voltage diaphragm for gas steady voltage valve, includes the diaphragm body the upper surface edge of diaphragm body is equipped with the arc sealing strip that makes progress the center department of diaphragm body is equipped with the sealed block cap that is used for chucking case.
The pressure stabilizing diaphragm for the fuel gas pressure stabilizing valve comprises the sealing clamping cap, wherein the sealing clamping cap comprises the round table protruding upwards, a round hole is formed in the lower end of the diaphragm body, a round clamping groove communicated with the round hole is formed in the round table, and the diameter of the round clamping groove is larger than that of the round hole.
According to the pressure-stabilizing diaphragm for the fuel gas pressure-stabilizing valve, the round table and the diaphragm body are integrally formed.
According to the pressure stabilizing diaphragm for the fuel gas pressure stabilizing valve, the round angle or the bevel angle structure is arranged at the edge of the opening of the round hole.
According to the pressure-stabilizing diaphragm for the fuel gas pressure-stabilizing valve, the arc-shaped sealing strip and the diaphragm body are integrally formed.
The pressure stabilizing diaphragm for the fuel gas pressure stabilizing valve is characterized in that the diaphragm body is of a circular structure.
In summary, the beneficial effects of the utility model are as follows: the arc-shaped sealing strips are arranged on the diaphragm body, so that the compression deformation of the diaphragm body in the assembly process can be reduced, the perception of the product on the gas pressure is improved, and the pressure stabilizing capability of the product can be improved when the diaphragm is used; in addition, the sealing clamping cap is arranged on the diaphragm body, so that leakage points of products in use can be reduced, assembly parts are reduced, and the assembly process is optimized.
