Problems solved by technology

According to the structure of the pressure regulating and throttling components, the gas pressure regulator can be divided into: stop type pressure regulator, diaphragm type pressure regulator, axial flow type pressure regulator, etc., its function is to automatically adjust the pressure of the gas outlet to make it stable In a certain pressure range, to meet the pressure value required by the user and meet the use requirements, the regulator is often equipped with a pilot to control the pressure of the gas outlet. However, the existing pilot has unstable control, which is easy to make the pressure adjustment Defects such as surge in the device

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 with figure 2 , an axial-flow pressure regulator, including a valve body 5 composed of an upper housing 2 with an air inlet 1 and a lower housing 4 with an air outlet 3, and a controller connected to the air inlet 1 and the air outlet 3 13. The valve body 5 is provided with an air containing chamber 6 and a balance film 9 for dividing the air containing chamber 6 into upper and lower chambers 7 and 8, and the upper chamber 7 communicates with the air outlet 3, The lower chamber 8 communicates with the controller 13 through a connecting pipe. There is also a sleeve 11 in the valve body 5. The bottom of the sleeve 11 is provided with a connected valve disc 10. The sleeve 11 is connected with the valve body 5 through a spring 12. The controller 13 is also in communication with the air inlet 1 and the air outlet 3, and th...

Abstract

The invention relates to an axial flow pressure regulator. The axial flow pressure regulator comprises a valve body consisting of an upper shell with an air inlet and a lower shell with an air outlet, and a controller connected with the air inlet and the air outlet; an air accommodating cavity is formed in the valve body, and a balance membrane for separating the air accommodating cavity into an upper cavity and a lower cavity is arranged in the valve body; the upper cavity is communicated with the air outlet; the lower cavity is communicated with the controller; a sleeve is arranged in the valve body; the bottom of the sleeve is provided with a connected valve clack; the sleeve is connected with the valve body through a spring; the controller consists of a director for controlling air pressure and a pressure stabilizer matched with the director. The axial flow pressure regulator has the characteristics of simple structure, stable output pressure, good pressure control and regulation performance and the like.

Description

technical field [0001] The invention relates to the technical field of pressure regulators, in particular to axial flow pressure regulators. Background technique [0002] The pressure regulator is widely used in the gas pressure regulating station and is the most important component in the gas pressure regulating station. Its function is to reduce the higher upstream gas pressure to the lower pressure of the pipe network or pipeline and keep it stable. According to the structural form of the pressure regulating and throttling components, the gas pressure regulator can be divided into: stop type pressure regulator, diaphragm type pressure regulator, axial flow type pressure regulator, etc., its function is to automatically adjust the pressure of the gas outlet to make it stable In a certain pressure range, to meet the pressure value required by the user and meet the use requirements, the regulator is often equipped with a pilot to control the pressure of the gas outlet. Howev...
