REGULATOR FOR REDUCING GAS PRESSURE

摘要

A regulator for reducing a gas pressure is provided to remarkably prevent an icing by installing a heat conductive pipe at an external peripheral surface of a sheet which is made of a thermal insulation material. A regulator for reducing a gas pressure includes a body(100), a diaphragm, a balance spring(300), and an opening control shaft. The body includes a gas inlet(110), a gas outlet(120), and a high-pressure room(130) between the gas inlet and the gas outlet. The diaphragm elevates and descends according to an amount of gas injected through the gas inlet. The balance spring supports the diaphragm elastically at a bottom of the pressure control screw for controlling a pressure of gas. The opening control shaft penetrates a flow path in the high-pressure room of the body and is fixed to operate together at a bottom of the diaphragm and controls opening/closing of the flow path. The flow path of the high-pressure room of the body includes an insulating sheet(500). A filter(700) is installed at a path between the gas inlet and the high-pressure room.
