Pig valve

Pig valve The best way to transport oil and gas is by pipeline, which has the advantages of high transport efficiency, low cost, low losses, and low environmental pollution.

To ensure the safety, efficiency, and smoothness of pipeline transportation, it is necessary to use a "pipe cleaner" to clean the pipeline. The "pig valve" and "pipe cleaner" together form a pipe cleaning operation device. It can be used as both the launch receiving device and the opening & closing valve of the pipe cleaner, which is called the "pipe cleaner launch receiving valve". (abbreviated as "pipe cleaner").

Pig Valve General Application

1. Before the new pipeline is put into operation, remove all kinds of residues in the pipe to make the pipeline unobstructed.
2. Rust removal and anticorrosion coating on the inner wall of new
3. Do regular oil pipe scraping wax and gas pipe de-watering on the put into the production. It can maintain an effective transmission capacity for a long time. At the same time, reduce the corrosion in the pipe wall and extend the service life of the pipeline.
4. It can be used as an isolation and quality exchange of different kinds of media conveyed in the same
5. Pipeline water pressure before exhaust and water pressure test after


Main Construction

The main types of products are mainly three types according to product function, usage, and pipe cleaning valve.

B type of pipe cleaning valve: pipe cleaner launch and receive the whole process of fluid flow without suspension. See figure (2)



Figure (2) B type pipe Pig Valve

C type: The fluid is not interrupted when the cleaner is launched and enters the cleaning valve, but when the pig was removed, the flow was interrupted briefly. (See Figure (1))



Figure (1) C type pipe cleaning valve

PS type Pig Valve: The fluid flow is interrupted for a short period during both launching and receiving purge, and the PS type is used when different types are transported in sequence or prevent mixing of transported (See Figure (3))

1. Main structural features and working principle
2. Structural features. The structural features of the cleaning valve are innovatively designed after adapting and increasing the functions based on the structural principle of the three-way ball valve.
3. Working principle. The working principle of a pipe cleaning valve is: the pipe cleaner is placed (or received) in the inner cavity of the sphere of the pipe cleaning valve, through the sphere in the “┴”- shaped (inverted “┬á” three-way valve body with mutual vertical, for reciprocal 90 ° rotation movement. When the sphering channel and the pipeline channel are on the same axis, the pipe cleaner is launched and received by the pipe cleaner valve under the fluid pressure in the pipeline, and its working principle is shown below. the principle is shown as follows.
