进口控温控压调节阀美国阿卡迪亚品牌

进口控温控压调节阀Product Description: The utility model relates to the technical field of a regulating valve, which is provided with a self sealing valve core and a valve rod, and a self sealing channel is arranged inside the valve rod. The self sealing valve core is composed of a sealing seat, a gas supply seat and a regulating element. The gas enters the self sealing valve core through the self sealing channel to provide a gas supply source for the sealing seat and the gas supply seat. When the external gas supply is interrupted instantaneously, the regulating element can be used to block the self sealing channel, The gas inside the seal seat and the air supply seat cannot flow back through the self sealing channel, which can make the seal seat and the air supply seat always in the expansion state,进口控温控压调节阀 that is, the self sealing valve core can still block the adjustment hole, so that the fluid can be controlled characteristic: The regulating valve is a final control element that changes the medium flow, pressure, temperature and other process parameters by receiving the control signal and using power. Therefore, the regulating valve is also known as the control valve. The regulating valve is usually divided into pneumatic regulating valve, electric regulating valve, hydraulic regulating valve and self operated regulating valve Principle: The sealing seat is fixedly connected with the bottom end of the valve rod, and the sealing channel runs through the sealing seat. The sealing seat is used to seal the regulating hole and adjust the size of the hole. The lower end of the sealing seat is provided with a gas supply seat, which is used to provide additional gas for the sealing seat, so that when the gas supply of the whole regulating valve body fails, the gas can be supplied to the sealing seat, so that the sealing seat will not open instantaneously, resulting in uncontrollable fluid, The maintenance time is saved for the maintenance personnel to avoid accidents. The part of the bottom end of the self sealing channel located inside the seal seat is provided with a plug-in hole, and the plug-in hole is equipped with an adjusting element. The adjusting element is used to prevent the gas in the air supply seat and the seal seat from flowing back into the upper chamber of the membrane chamber when the air supply of the whole regulating valve body fails, resulting in the opening of the self sealing valve core.
