Gas pressure regulator with good air tightness

Abstract

The invention relates to the technical field of gas pressure regulators, in particular to a gas pressure regulator with good air tightness. The gas pressure regulator comprises a diaphragm lower shell, a diaphragm upper shell and two spherical sleeves, wherein a pressure regulating device is installed in the diaphragm upper shell; the diaphragm lower shell is connected with the diaphragm upper shell through a quick connecting device; the quick connecting device is connected with a plurality of support columns; the support columns are connected with sliding sleeves through sliding blocks; springs are connected between the sliding sleeves and the sliding blocks; the sliding sleeves are connected with the diaphragm lower shell; the diaphragm lower shell communicates with an air inlet pipe and an air outlet pipe; the air inlet pipe and the air outlet pipe are both connected with spherical ventilation blocks; the two spherical sleeves are both connected with flange plates through mounting pipes; a plurality of inner wall sealing mechanisms are connected to the interiors of the mounting pipes through supporting frames; elastic sealing barrels are installed on the inner wall sealing mechanisms through plate rolling rings; a transmission mechanism and a rubber top ring are slidably connected to the interior of each mounting pipe; and the rubber top rings are connected with the transmission mechanisms. According to the gas pressure regulator, maintenance and repair are convenient, air tightness is good, use safety is high, the mounting angle is easy to adjust, and practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of gas pressure regulators, in particular to a gas pressure regulator with good airtightness. Background technique [0002] As we all know, a gas pressure regulator with good airtightness is an auxiliary device used to adjust the gas pressure in the gas pipeline during the gas transportation process, so that the gas pressure is more stable and the use is safer. field is widely used. [0003] The existing gas pressure regulator with good airtightness includes a valve body, the valve body is fixedly connected with a diaphragm lower case through the lower case connector, the top of the diaphragm lower case is fixedly connected with a diaphragm upper case, and the diaphragm upper case There is a diaphragm between the lower casing and the lower casing of the diaphragm, and a pressure regulating device is installed on the upper casing of the diaphragm. Both ends of the valve body are fixedly connected with flange...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned prior art solutions still have the following defects. The connection and disassembly between the diaphragm upper case and the diaphragm lower case are relatively laborious, and the maintenance and repair are relatively laborious. The connection between the pipes is poorly sealed, the safety of use is low, the angle between the valve body and the flange is not easy to adjust, the installation limitations are high, and the practicability is poor
