Embodiment Construction

[0015] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0016] Such as figure 1 A self-supporting natural gas pressure regulator is shown, including a pilot 1, a throttle needle valve 2 and a main pressure regulator 3. The main pressure regulator 3 is installed on the natural gas pipeline and divides the natural gas pipeline into an inlet pipeline 5 And the outlet pipeline 6, the pilot 1, the throttle needle valve 2, the main pressure regulator 3, the inlet pipeline 5 and the outlet pipeline 6 are connected with the pressure guiding pipe 4; the main pressure regulator 3 includes the main regulator Pressure regulator film 31, main pressure regulator spring 32 and main pressure regulator va...

Abstract

The invention relates to the technical field of natural gas pipeline conveying equipment, in particular to a natural gas self-standing pressure regulator which can be widely applied to a door station, a distribution station and a pressure regulating metering station of a natural gas supply system. The natural gas self-standing pressure regulator comprises a director, a throttle needle valve and a main pressure regulator body; the main pressure regulator body is arranged on a natural gas pipeline to divide the natural gas pipeline into an inlet pipeline body and an outlet pipeline body; and a connecting pipe is connected among the director, the throttle needle valve, the main pressure regulator body, the inlet pipeline body and the outlet pipeline body. The natural gas self-standing pressure regulator has the advantages of being small in size, light, reliable in performance, convenient to mount, high in sensitivity, good in pressure regulating performance and the like; and due to the fact that air flow does not directly impact a thin film, the thin film is not prone to being damaged and is long in service life.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline transportation equipment, in particular to a self-supporting natural gas pressure regulator widely used in gate stations, distribution stations and pressure regulation and metering stations of natural gas supply systems. Background technique [0002] A pressure regulator is a device used for pressure regulation in a natural gas transmission system. The pressure regulator adjusts the higher inlet pressure to the lower outlet pressure, and automatically controls the outlet pressure within a certain set value as the natural gas demand changes. The self-supporting pressure regulator uses the change of the pressure of the regulated medium itself to directly change the opening of the valve, that is, to change the flow area of ​​the valve, and to adjust the pressure through the adjustment of the flow. The traditional self-supporting pressure regulator has a complex structure, and the airflo...
