Safe anti-explosion gas pressure regulator

Abstract

The invention relates to a safe anti-explosion gas pressure regulator. A throttling safety device is arranged at an interface position of a pressure regulating gas chamber and an inlet pipe; a safetybase of the throttling safety device is sealed and fixed on the inlet pipe; a vent hole is arranged in the safety base; a throttling safety valve core is arranged in the inlet pipe and matched with asealing surface of one opening at one end of the safety base; a reset ejecting bar penetrates through the vent hole; two ends of the reset ejecting bar are respectively matched with the throttling safety valve core and a closing plug; the closing plug is linked with one end of a hinge rod hinged on the safety base, while the other end of the hinge rod is connected with the connecting rod; and theconnecting rod penetrates through a flexible diaphragm and is connected with a reset switch outside the pressure regulator. The safe anti-explosion gas pressure regulator overcomes the defect that thecommon pressure regulator can not cut off gas source automatically when gas leaks. By adopting the specific design, the safe anti-explosion gas pressure regulator can eliminates gas safety accidentscaused by self-owned diaphragm rupture of the pressure regulator, or falling off, aging crack and rupturing by rat-bite of a gas rubber tube (hose), and the like, and the safe anti-explosion gas pressure regulator has the advantages of simple structure, high sensitivity, convenient reset operation and safe and reliable use.

Description

technical field [0001] The invention relates to a safety explosion-proof gas pressure regulator. Background technique [0002] With the enhancement of people's awareness of environmental protection and the improvement of living standards, the rate of gas use in people's homes is getting higher and higher. Gas is an environmentally friendly, clean, efficient and resource-rich energy source, and it is now more and more favored and valued by countries all over the world. Gas includes natural gas, liquefied petroleum gas, coal gas and other gas sources. [0003] As a product for decompression and pressure regulation of gas, the gas pressure regulator is often seen in our daily life, and it is an indispensable product. Most of the existing gas pressure regulators on the market are ordinary gas pressure regulators without explosion-proof security functions. Although there are a small number of gas pressure regulators with explosion-proof security functions, the existing There a...
