Abstract
The invention provides a special gas pressure reducer and aims to solve the problem that pressure reducers in the prior art are low in sensitivity in pressure regulation. The special gas pressure reducer comprises a valve body, an upper cover and a pressure regulation device. The valve body is provided with a gas inlet hole and a gas outlet hole, internally provided with a high-pressure cavity connected with the gas inlet hole and internally provided with a low-pressure cavity connected with the gas outlet hole, and a piston is arranged above a filter screen which is arranged between the high-pressure cavity and the low-pressure cavity. The valve body is internally provided with a slide groove, a seal block is fixedly connected with a slide rod which is arranged in the slide groove, and a first spring sleeves the slide rod between the seal block and the slide groove. The pressure regulation device comprises a regulation bolt, a pressure plate, a second spring, a main plate, a vertical rod, a small gear, a large gear and a pressure regulation handle. The pressure regulation handle is rotated to enable the small gear to drive the large gear, and then the regulation bolt is driven to regulate gas pressure; when the handle rotates by a same angle, the regulation bolt moves forward by a shorter distance, higher sensitivity in pressure regulation is achieved, and higher efficiency and higher stability in regulation of a required pressure can be realized.
