The gas proportional valve comprises a valve body, a cutoff device and an adjusting device, wherein the cutoff device and the adjusting device are arranged on the valve body, a gas inlet cavity and a gas outlet cavity are formed in the valve body and communicate with each other, a first mounting groove is formed in the top of the valve body, the cutoff device comprises a first mounting plate arranged in the first mounting groove, a first electromagnet arranged on the first mounting plate and a first push rod arranged below the first electromagnet, a first through cavity is formed in the top of the air inlet cavity, a first baffle is arranged in the air inlet cavity, a sealing plate matched with the first through cavity is arranged at the top of the first baffle, a sealing spring is arranged at the top of the sealing plate, a first groove matched with the sealing spring is formed in the inner wall of the first through cavity, and the first push rod is arranged in the first through cavity in a penetrating mode.

Description

technical field [0001] The invention belongs to the technical field of gas equipment, and in particular relates to a gas proportional valve. Background technique [0002] Gas valve is a safety supporting device used to control gas pressure, flow and other technical parameters in gas pipeline engineering. It is used to cut off, connect and adjust the gas in the pipeline. It has good control characteristics and closing and sealing performance. It is suitable for City gas, liquefied petroleum, natural gas, oxygen and other gas medium pipelines. [0003] When the gas is transported in the pipeline, in order to prevent gas leakage, the pipeline will only be opened when needed. The existing valve switch is relatively complicated, and there are many inconveniences in use, and the practicability is not high. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the present invention provides a reliable gas proportional valve. [0005] In orde...
