Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valves, in particular to a super-strong automatic pressure reducing regulator. Background Art

[0002] A pressure reducer is a device that reduces the pressure of high-pressure oxygen stored in an oxygen cylinder to low-pressure oxygen required for gas welding. Since the pressure in the cylinder is high, while the pressure required for gas welding and gas cutting is low, a pressure reducer is needed to reduce the high-pressure gas stored in the cylinder to low-pressure gas, and the required working pressure should be kept stable from beginning to end. In short, a 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] The Chinese patent publication number is CN218094478U, a pressure regulator, the technical solution provided by the patent document is: in the past, it was impossible to use a gas meter with a safety function to detect gas leakage on the gas equipment side, there was a risk of explosion, and it was possible to use it without noticing the gas leakage. The pressure regulator of the utility model can improve the safety of gas use without using a gas meter with a safety function. The pressure regulator has: a diaphragm, one side of which is subjected to the pressure of the gas and the other side is subjected to the pressure of the atmosphere; and a valve, which reduces the pressure of the gas supplied from the gas container according to the position of the diaphragm and supplies the decompressed gas to the gas equipment side. The pressure regulator also has: a flow measurement unit that measures the flow of the gas after being decompressed by the valve; and a leakage determination unit that determines whether there is a gas leakage on the gas equipment side based on the flow of the gas.

[0004] In order to solve the problem that the existing device does not use a gas meter with a safety function and directly connects the gas equipment to the pressure regulator, the existing technology adopts a method of installing a gas meter with a safety function and additionally installing other gas leak detectors. The gas leak can be detected only by replacing the pressure regulator used in the past. However, the flanges fixed at both ends may become loose after long-term use, which may lead to a decrease in the stability of the pressure reducing valve during operation. Utility Model Content
