Abstract

The invention discloses a gas pressure regulator which comprises a valve body and a pilot valve, wherein a gas inlet channel and a gas outlet channel as well as a valve rod are respectively arranged in the valve body, the lower end of the valve rod is arranged between the gas inlet channel and the gas outlet channel, the gas outlet channel is connected with a gas tube, a spring is sleeved on the lower end of the valve rod, a skin membrane is arranged on the upper end of the valve rod and positioned in a cavity at the upper end of the valve body and used for dividing the cavity into an upper skin membrane cavity and a lower skin membrane cavity, the pilot valve is respectively connected with the gas inlet channel, the gas tube, the upper skin membrane cavity and the lower skin membrane cavity, a ventilating hole is arranged on the skin membrane, and the upper skin membrane cavity is communicated with the lower skin membrane cavity through the ventilating cavity. The invention has the advantage that the gas pressure regulator has lower use cost, reduces gas leakage points and is convenient for controlling flow.

Description

technical field [0001] The invention relates to a gas pressure regulating device, in particular to a gas pressure regulator. Background technique [0002] The gas pressure regulator is a device used to regulate the pressure of natural gas, liquefied petroleum gas, artificial gas, mine gas and other non-corrosive gases. The gas pressure regulator is suitable for large inlet pressure fluctuations, medium and low pressure, and large flow Gate station or zone pressure regulation. Needle valves are used in existing gas pressure regulators, which increases gas leakage points, makes it difficult to control the flow rate, and increases the cost of use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas pressure regulator with low operating cost and convenient control. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a gas pressure regulato...
