Description

technical field

[0001] The invention relates to a gas safety heating proportional controller, which belongs to the technical field of gas safety regulation and control. Background technique

[0002] The main function of the gas regulating device is to open and close the gas passage and adjust the gas flow. Existing gas control devices generally adopt pilot-operated permanent magnet voltage control. Due to the difference in structural design, there are common defects such as unclear adjustment of voltage input and valve flow ratio, low precision, bulky volume, easy leakage, and long closing time. Contents of the invention

[0003] The purpose of the present invention is to provide a gas safe heating proportional controller with reasonable design, which can effectively and safely realize the opening and closing of the gas channel, and has functions such as quick closing, delayed opening, proportional flow adjustment and stable outlet...
