Product working principle and use:

Pigging valve is a new type of valve mainly used for cleaning pipelines in water, oil, natural gas and other long-distance pipelines. It is used for launching and receiving pigs. With the corresponding pig, it can easily complete the work of pipeline cleaning, emptying and isolation, sequential delivery of media, inspection of the pipeline system and so on. It can completely replace the traditional pig transmitting and receiving device with the pig receiver as the core. The structure of pigging valve is a new type of valve that is innovatively designed after modification and addition of functions based on the structure of fixed ball valves. Completely inherited the performance characteristics of the two-position shut-off ball valve, the valve can be opened and closed through 90 ° rotation of the core, which is convenient to design as a double block and bleed to make the valve fully open or closed. Can discharge the medium in the body cavity, this function is exactly necessary for the pigging valve.

A branch pipe is set on the side of the valve body. The center of the branch pipe perpendicularly intersects the pipeline center. Quick opening blind plates and vent valves are installed on the branch pipe, so that the pig can be easily closed in or taken out of the pig valve. The diameter of the ball through hole Larger, one end of the through hole is provided with a stopper that can prevent the pig from passing through but allows the medium to flow.

100% pressure test to ensure no visible leakage at any sealing parts; fire-resistant safety design, when the elastic valve seat is burned, a metal-to-metal seal is formed between the ball valve and the valve seat; the valve body and the valve cover and the valve stem are all Equipped with high temperature resistant graphite gaskets to ensure high temperature sealing reliability, fire resistance test meets API 6FA and API 607 standards requirements; antistatic design, static conductive springs ensure good conduction between the ball, valve stem and valve body, safely lead to friction Of static electricity.

Product structure characteristics:

1.Top-mounted valve body design realizes online valve maintenance
2. The valve stem is not affected by the thrust of the sphere, the valve stem can be twisted freely, and the valve is easy to operate.
3.Easy operation of quick opening blind plate
4.Zero leakage
5.Interlocking design ensures the safety of operators
6, fire safety design, fire test in compliance with AP, 6FA and AP, 607 standards
7.Antistatic design
8.Cleaning design
