A multi-stage pressure regulator for natural gas recovery

Abstract

The invention discloses a multi-stage pressure regulator for recovery of natural gas, which comprises a base, an elastic mechanism, a primary pressure regulating mechanism and a secondary pressure regulating mechanism. Both ends of the top of the base are symmetrically fixed with elastic mechanisms. The tops of the elastic mechanisms are all fixedly connected to the bottom of the body, and the tops of the body are slidably connected to the organic cover, and the center of the top of the cover is fixedly installed with a primary pressure regulating mechanism, and the output end of the primary pressure regulating mechanism passes through The rotating shaft is connected with an eccentric drum, and the side wall of the eccentric drum is uniformly provided with a number of installation grooves, and the first spring is fixed and fixed up and down symmetrically in the installation groove of the eccentric drum, and the first spring is far away from the eccentric One end of the drum is fixedly connected with one end of the ejector rod. This multi-stage pressure regulator for natural gas recovery is simple in structure and easy to operate. It realizes the adjustment of natural gas pressure in a safe and stable working environment, and is more practical. high.

Description

technical field [0001] The invention relates to the technical field of natural gas recovery, in particular to a multi-stage pressure regulator for natural gas recovery. Background technique [0002] Natural gas is a gaseous fossil fuel mainly composed of methane. It mainly exists in oil fields and natural gas fields, and a small amount comes out of coal seams. Like crude oil, natural gas is also buried in underground closed geological structures, some of which are stored in the same layer as crude oil, and some exist alone. For natural gas stored in the same layer as crude oil, it will be extracted together with crude oil. The main purpose of natural gas is as fuel, which can produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low molecular weight hydrocarbons and non-hydrocarbon gases. [0003] It is necessary to adjust the air...

Problems solved by technology

[0003] It is necessary to adjust the air pressure of natural gas during recovery, otherwise it is not conducive to the operation of personnel. In the process of air pressure adjustment, it is necessary to adjust the pressure. The one-time air pressure adjustment is not only difficult but also difficult to achieve. Therefore, we propose A multi-stage pressure regulator for natural gas recovery
