Radial flow valve element underground pressure regulating device

Abstract

The invention discloses a radial flow valve element underground pressure regulating device. The radial flow valve element underground pressure regulating device comprises a diffusion tower and a pressure regulating device arranged underground. A base of the diffusion tower is buried underground, an integrated electronic instrument box is arranged at the overground position of the diffusion tower, and a pressure recorder and pressure sensors are mounted in the integrated electronic instrument box. The pressure regulating device comprises a pressure regulating valve body, a pressure regulating instrument box and a box cover, the pressure regulating valve body is arranged on the lower portion of the pressure regulating instrument box, and the pressure regulating instrument box comprises a connecting bottom disc, an inlet pressure meter, a differential pressure gauge, a director, a diffusion valve, a stop valve drive device, a drain valve and an outlet pressure meter, wherein the inlet pressure meter, the differential pressure gauge, the director, the diffusion valve, the stop valve drive device, the drain valve and the outlet pressure meter are mounted on the connecting bottom disc. The pressure regulating valve body comprises a pressure regulating valve element, an inlet valve, an inlet pipe, an outlet pipe and an outlet valve. The radial flow valve element underground pressure regulating device aims at achieving the purposes of being compact in structure, safe and reliable, has the functions of gas filtering, overpressure diffusion, overpressure cutting off and pressure regulating, can also achieve data external display and remote transmission, and overcomes the defect that an underground pressure regulating device is inconvenient to patrol.

Description

technical field [0001] The invention relates to the technical field of gas transmission and distribution, in particular to an underground pressure regulating device for a radial flow valve core. Background technique [0002] Most of the domestic traditional gas pressure regulating devices are arranged on the ground, and the valves, filters, shut-off valves, pressure regulators and other equipment are connected in sequence through pipelines inside the box. This device has the following defects: 1. It takes up a lot of space and is complicated to maintain. 2. It is easy to block the line of sight and damage the landscape. 3. There is a risk of gas leakage caused by being hit by a vehicle. 4. To adjust the pressure, you must go to the scene. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a compact, safe and reliable radial flow valve core gas underground pressure regulating device, which has functions of ...
