Abstract

The invention provides a natural gas solenoid valve, and belongs to the technical field of solenoid valves. The natural gas solenoid valve comprises a valve body, a hard-core membrane, a valve deck, a permeable sleeve, a guide sealing head, a tension spring and an explosion-proof solenoid coil. The hard-core membrane and the valve body are sealed. A control gas nipple of the hard-core membrane and the guide sealing head are in joint seal through the tension spring. The guide sealing head is matched with a cylindrical surface of the permeable sleeve. The explosion-proof solenoid coil is installed on the permeable sleeve. The hard-core membrane is formed by riveting a membrane body, a liner bowl, a liner pad and the control gas nipple, wherein the diameter of the liner bowl is 1.3-1.5 times that of a gas outlet channel of the valve body, the diameter of the liner pad is smaller than that of the gas outlet channel of the valve body, and the diameter of the control gas nipple is larger than that of a gas inlet hole of the waveform membrane body. The natural gas solenoid valve is simple in structure, fast to assemble, convenient to maintain, and capable of being widely applied to the natural gas industry. The natural gas solenoid valve realizes automatic control in the transmission process of natural gas, and is quick in response, high in reliability and particularly suitable for emergency cut-off.

Description

technical field [0001] The invention relates to the technical field of solenoid valves, in particular to a natural gas solenoid valve, which is suitable for opening and closing in natural gas and explosive gas delivery pipelines. Background technique [0002] As an environmentally friendly energy source, the application of natural gas is becoming more and more common. The development of compressed natural gas production, transportation and application technology has driven the demand for pipeline transportation control components - explosion-proof solenoid valves for natural gas, and gradually matured and formed a series of high-pressure, Solenoid valves for large-diameter natural gas. At present, there are straight-through explosion-proof solenoid valves for natural gas pipelines, pilot-operated on-off gas valves, and unloading high-pressure explosion-proof solenoid valves to prevent well jumping. This type of solenoid valve has complex structure, large shape and heavy weig...
