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 the “pipe cleaner” to clean
the pipeline. The “pig valve” and “pipe cleaner” together from 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
- Before the new pipeline is put into operation, remove all kinds of
residues in the pipe to make the pipeline unobstructed.
- Rust removal and anticorrosion coating on the inner wall of new
- 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.
- It can be used as an isolation and quality exchange of different
kinds of media conveyed in the same
- Pipeline water pressure before exhaust and water pressure test
after
Pig Valve General Information
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))
Figure (3) S type Pig Valve
- Main structural features and working principle
- 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.
- Working principle. The working principle of 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.
