Pipe Cleaning Valve, Large Diameter Pipe Cleaning Valve

Pipe cleaning valve (also known as PIG) Pipe cleaning valve solves the problem that the inner wall of the pipeline will be deposited or formed with dirt during long-term use. These deposited dirt deposited on the pipeline wall will increase the resistance of the fluid during transportation. Before laying a new pipeline, various residues in the pipe should be cleaned and the inner wall of the pipeline should be coated with rust removal and anti-corrosion layer to make the pipeline unobstructed. In the running natural gas and heating pipelines, wax, scale and water will be deposited inside the pipeline, which will affect the pipeline transportation capacity. Cleaning operations can reduce the corrosion of various substances on the inner wall of the pipeline and reduce the operating resistance. Chemical material and oil pipelines have polymeric material deposits in the pipeline. Using a pipe cleaner to perform non-stop pipe cleaning operations can avoid re-laying the pipeline and reduce production costs.

Features of Jingpai Pipe Cleaning Valve Quick Opening Door:

Jingpai quick opening door has completely independent intellectual property rights. The quick opening door has an internal pressure protection function. It cannot be forced to open the quick opening door before the pressure is released. The quick opening door with a larger diameter is equipped with a rocker hinge device to prevent accidental opening and staggered opening, reducing the probability of casualties and property losses. The operation is convenient and fast and the patent ZL2018 2 0226964.1 has been applied for.

Features of Jingpai removable pig-blocking fence:

Jingpai removable fence has completely independent intellectual property rights. This PIG valve has multiple uses. This PIG is suitable for the middle section of long-distance pipelines. When the pipeline needs to be cleaned, the removable fence pigging valve can replace the severely worn pig in the middle section to more effectively clean the stratification and dirt on the inner wall of the pipeline and increase the pipeline flow capacity. Or when the pig does not need to be replaced in the middle, the fence inside the removable fence pigging valve is removed. So that the pig can pass through the PIG valve smoothly. It can also reduce the running resistance and pressure loss of the baffle in the cleaning valve, greatly improve the economic value, and apply for patent ZL2019 1 0409834.0.

Features of Jingpai cleaning ball collection assembly pipeline residue collection and quick discharge system:

Jingpai's system has completely independent intellectual property rights. When the pipeline cleaning operation is nearing the end, when the cleaning device enters the cleaning ball collection assembly pipeline residue collection and quick discharge system, it can effectively collect and quickly discharge the residue in the pipeline, and reduce the residue in the pipeline passing through the cleaning valve. Cause the cleaning valve to be stuck and scratch the valve seat sealing surface and the ball to cause the cleaning valve to leak. The problem of discharge can be eliminated by eliminating the ball collection cylinder. The ball collection cylinder needs to build a ball collection station, which requires a large site, complex structure and high cost. And applied for patent ZL2019 2 0706143.2.

Pipe cleaning valve type

Type B: Pipe cleaning valve type B is a bypass type pipe cleaning valve with a flow area of ​​about 25% of the pipe cross-sectional area. This structure will not cause the PIG to stop flowing even when launching or receiving the pig. Therefore, type B cannot be used as a shut-off valve.

type B

Type C: Type C is a standard type of pig valve. Its ball hole passage area is slightly larger than the inner diameter flow surface of the pipe. When receiving or transmitting, the C-type PIG valve will cut off the medium delivery in the pipeline. Therefore, the C-type can be used as a DBB ball valve.

Type C

Note:

Each PIG valve can be used as a pipe cleaning ball valve or a pipe cleaning ball valve, but the installation direction of the pipe cleaning valve must be distinguished during installation. When used as a pipe cleaning ball valve, the end with the fence on the valve seat must be installed at the upstream end of the pipeline. When used as a pipe cleaning ball valve, the end with the fence on the valve seat must be installed at the downstream end of the pipeline. When used as a pipe cleaning ball valve, a waste collection container can also be installed in front of the PIG valve and equipped with a receiver/transmitter. The ball collection quick discharge system is a patented product of the Jingpai pipe cleaning valve, and an indication will be given when the pipe cleaning device is exhausted.
