Safe pressure reducer

Abstract

The invention discloses a safe pressure reducer. The safe pressure reducer comprises an air bottle; a pressure reducer is connected with the air bottle; an exhaust joint is arranged on the air bottle; an intake joint is arranged on the pressure reducer; a handle is arranged on the air bottle; a gear is fixedly connected below the handle; a rack is matched with the gear; bulbs are arranged at the end parts of the rack; the intake joint of the pressure reducer is provided with a guide rail; a stand column is arranged on the guide rail; two universal joint cup bowls are arranged at the end parts of the stand column; and the bulbs are wrapped in the universal joint cup bowls. The safe pressure reducer has the following beneficial effects: the precise control of the rotating speed of the air bottle is realized by using matching between the gear and the rack; the safety of the whole device is greatly improved; and the service life of the whole device is prolonged.

Description

technical field [0001] The invention belongs to the field of pressure reducers, in particular to a safety pressure reducer. Background technique [0002] Since the pressure in the gas cylinder is relatively high, but the pressure required for gas welding and gas cutting and the point of use is relatively small, it is necessary to use a pressure reducer to reduce the high-pressure gas stored in the gas cylinder to a low-pressure gas, and it should be ensured The required operating pressure remains constant throughout. In short, the pressure reducer is a regulating device that reduces high-pressure gas to low-pressure gas and keeps the pressure and flow of the output gas stable. [0003] When the oxygen cylinder is just opened and deflated, the movement must be slow. If the valve opening speed is too fast, the temperature of the gas in the working part of the pressure reducer will be greatly increased due to adiabatic compression, which may cause parts made of organic materi...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the present invention provides a safety pressure reducer to solve the problem that the speed of opening the gas cylinder by hand is not easy to control during the use of the existing pressure reducer. If it is too fast, the pressure reducer will be opened. The internal components are damaged, and the pressure gauge is too high to cause failure.
