Abstract

This utility model discloses a portable pressure regulator with a movable flange connection, including a valve body and an actuator and a shut-off device installed in the middle of the valve body. Both the inlet and outlet of the valve body are connected to ball valves. A movable flange and a stop are installed at the end of the ball valve connected to the gas pipe. The movable flange is screwed to the outer cylindrical surface of the ball valve. The stop has external threads and a shoulder, and is screwed to the inner cylindrical surface of the ball valve. The shoulder of the stop fits against the end face of the ball valve, and a sealing gasket I is provided between the shoulder of the stop and the ball valve. The movable flange of this pressure regulator, screwed to the ball valve, can rotate and move up and down. During on-site installation, the relative position of the flange can be adjusted to reduce or eliminate pipeline stress during installation, facilitating assembly.

Description

A portable pressure regulator with movable flange connection

technical field

The utility model specifically relates to a movable flange connection portable pressure regulator.

Background technique

The gas pressure regulator is commonly known as a pressure reducing valve, also known as a gas pressure regulating valve. It is a device that keeps the outlet gas at a specified pressure by automatically changing the gas flow through the regulating valve. Usually divided into two types: direct acting and indirect acting. The pressure regulator is a special valve on the gas pipeline. It is a device that can keep the downstream pressure stable no matter how the gas flow and upstream pressure change. It can reduce the upstream pressure to a stable downstream pressure. When the pressure regulator fails It is possible to limit the downstream pressure in a safe range.

In the existing gas pressure regulator, the connecting flange and the ball valve are an integral body, and the position of the flange is fixed and cannot be adjusted. In the actual field installation, the position of the flange connected to the pressure regulator may be deviated, which may cause difficulty or even impossibility in installation. The situation of the installation.

Utility model content

The purpose of the utility model is to overcome the disadvantages of the prior art and provide a movable flange-connected portable pressure regulator to solve the problem that the installation of the existing pressure regulator is difficult or even impossible due to the deviation of the flange position.

In order to achieve the above purpose, the technical solution adopted by the utility model is to provide a movable flange connection portable pressure regulator, including a valve body, an actuator and a cut-off device installed in the middle of the valve body, the air inlet of the valve body There is a ball valve connected to the gas outlet. The end of the ball valve connected to the gas pipe is equipped with a movable flange and a stopper. The movable flange is screwed to the outer cylindrical surface of the ball valve; The stopper is screwed to the inner cylindrical surface of the ball valve, the shoulder of the stopper is attached to the end face of the ball valve, and a sealing gasket I is arranged between the shoulder of the stopper and the ball valve.

Preferably, a stepped hole is provided at one end of the stopper located inside the ball valve, and a sealing gasket II located in the stepped hole is provided between the stopper and the ball valve.

Preferably, the stopper is made of cast iron.

The beneficial effects of the utility model are:

1. Both the air inlet and the air outlet of the valve body of the present utility model are connected with a ball valve, and the end of the ball valve connected to the gas pipe is equipped with a movable flange and a stopper, and the movable flange is screwed to the outer cylindrical surface of the ball valve; There are external threads and shoulders on the outside of the stopper. The stopper is screwed to the inner cylindrical surface of the ball valve. The shoulder of the stopper is attached to the end face of the ball valve. There is a sealing gasket Ⅰ between the shoulder of the stopper and the ball valve. . The movable flange and the ball valve can be rotated and moved up and down, and the relative position of the flange can be adjusted when the pressure regulator is installed on site, so as to reduce or eliminate the pipeline stress during installation and facilitate assembly.
