Description

PE valve capable of achieving secondary welding

Technical Field

The utility model relates to a gas valve technical field, more specifically say, the utility model relates to a but PE valve of secondary butt fusion.

Background

At present, the valve used by a gas polyethylene pipeline system is mostly of a type with diffusion, namely, two sides of the valve are provided with a diffusion pipe leading to the outside of the pipeline in various modes, and the valve is used for gas diffusion, gas replacement, pressurization, pressure detection and other effects. The external connected mode of diffusing pipe root that each company used at present has hot melt socket joint to connect, electric smelting connects etc. hot melt socket joint welding, electric smelting connect because there is not pressure among the welding process and possible oxide layer scrapes not thoroughly, leads to the rosin joint very easily, uses for a long time and takes place to leak, leaks the position and is located the face of weld, but because the whole one shot weld shaping of valve, does not reserve the surplus of maintaining, leads to only solving the difficulty through changing whole valve.

SUMMERY OF THE UTILITY MODEL

It is an object of the present invention to solve at least the above problems and to provide at least the advantages which will be described later.

The utility model discloses it is still another purpose to provide a but PE valve of secondary butt fusion.

In order to realize the above purpose, the utility model provides a but PE valve of secondary butt fusion, a serial communication port, include:

the device comprises a main valve, communicating pipes symmetrically arranged at the left end and the right end of the main valve, a release port vertically arranged on the communicating pipes and protective pipes vertically arranged on the left-right symmetrical center line of the main valve; the main valve is cylindrical, a through hole which is communicated left and right is formed in the main valve, a fillet is arranged at the joint of the main valve and the communicating pipe, the communicating pipe is a circular pipe, the diffusing port is a circular pipe with a stepped inner wall, and the communicating pipe is communicated with the inside of the main valve.

Preferably, the thickness of the tube wall of the communicating tube is 3 mm.

Preferably, the thickness of the tube wall of the protection tube is 2 mm.

Preferably, the communicating pipe and the dispersing opening are made of a high-density polyethylene material modified by an antistatic agent.

Preferably, the protection pipe includes a heat insulating layer, a waterproof layer, and a metal layer.

Preferably, the diameter of the outer pipe of the dispersion opening is smaller than that of the inner pipe of the communicating pipe.

The utility model discloses at least, include following beneficial effect:

1. a but PE valve of secondary butt fusion, it can not carry out the secondary to the mouth that diffuses to the valve and repairs, has designed and has diffused mouthful secondary device of repairing, the valve diffuses mouthful welding department again and takes place to leak the back, can carry out the secondary and repair, avoids changing whole valve and causes great loss.

2. But PE valve of secondary butt fusion, its simple structure, reasonable in design is fit for using widely.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Detailed Description

The present invention is further described in detail below with reference to the drawings and examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, in one embodiment of the present invention, a PE valve capable of secondary welding is provided, which includes:

the device comprises a main valve 1, communicating pipes 2 symmetrically arranged at the left end and the right end of the main valve 1, a release port 3 vertically arranged on the communicating pipes 2, and protection pipes 4 vertically arranged on the left-right symmetrical center line of the main valve 1; the main valve 1 is cylindrical, a through hole which is communicated left and right is formed in the main valve 1, a fillet is formed at the joint of the main valve 1 and the communicating pipe 2, the communicating pipe 2 is a circular pipe, the diffusing port 3 is a circular pipe with a stepped inner wall, and the communicating pipe 2 is communicated with the inside of the main valve 1.

Further, the thickness of the pipe wall of the communicating pipe 2 is 3 mm.

Further, the thickness of the pipe wall of the protection pipe 4 is 2 mm.

Further, the communicating pipe 2 and the dispersion opening 3 are made of a high-density polyethylene material modified by an antistatic agent.

Further, the protection tube 4 includes a heat insulating layer, a waterproof layer and a metal layer.

Further, the diameter of the outer pipe of the dispersion opening 3 is smaller than that of the inner pipe of the communicating pipe 2.

The utility model discloses a use method does: according to the standard welding depth requirement, the distance (about 25mm) of a half of the welding insertion depth of the diffusion pipe 5 into the diffusion opening 3 is cut off transversely after one-time welding fails, the welding size is milled by using a special milling cutter, and then secondary welding is carried out, for example, if no special milling cutter is arranged on the using field, the welding root of the diffusion pipe 5 can be cut, and the outside of the diffusion opening 3 is welded by using an electric melting sleeve 6.
