Abstract

The invention relates to the field of fuel gas safety valves, and discloses a household fuel gas self-closing valve with small force loss. The household gas self-closing valve comprises a valve pipe body, a first valve seat and a second valve seat are arranged on the gas inlet side of an inner cavity of the valve pipe body, a driving pipe is arranged in the middle of the inner cavity of the valvepipe body, a valve rod capable of moving transversely is arranged on one side of the driving pipe, and one end of the valve rod is fixedly connected with a valve element located between the first valve seat and the second valve seat. According to the household fuel gas self-closing valve with the small force loss, through the structural design that the valve element is located between the first valve seat and the second valve seat in the valve pipe body, the valve pipe body, a linkage pipe body and the driving pipe communicate through a metal through pipe and a guide pipe, under-pressure safety protection, over-current safety protection and overpressure safety protection effects are achieved, and at the same time, compared with an existing fuel gas safety self-closing valve, the fuel gas self-closing valve has the advantages that the balance mode of an elastic membrane is canceled, and the problem that the elastic membrane is prone to misoperation due to the influence of elastic fatigue during normal pressure supply balance is effectively solved.

Description

technical field [0001] The invention relates to the field of household gas safety valves, in particular to a household gas self-closing valve with small force loss. Background technique [0002] Natural gas is a kind of green fuel energy that people cannot do without today, especially in cities, almost every household uses natural gas. While natural gas brings convenience to people, it also has certain hidden dangers. Therefore, it is necessary to A gas self-closing valve is set between the gas stove and the gas supply. When problems such as overvoltage, undervoltage, and overcurrent occur in the gas supply, the valve will be automatically closed in time to avoid damage caused by gas leakage. [0003] However, the elastic diaphragm of the existing gas safety valve is in an elastic working state when the normal supply pressure is balanced. After a long time, it is easy to malfunction due to the influence of elastic fatigue. The force is turned into a lateral force to pull th...
