                Pigging valve is mainly used for water, oil, natural gas pipeline cleaning in the new valve, more easily complete the pipeline cleaning, emptying, isolation and orderly transmission of media, testing pipeline system and other work. It can completely replace the complex pigging launching and receiving device with the traditional pigging transceiver as the core, and also has the function of universal two-way intercepting ball valve. Also known as the PIG valve.

                Working Principle: Pigging valve will be through the pigging valve into the pipeline, under the pressure of medium, its removal of impurities in the pipeline, pigging valve should be used in pairs, its function is to launch the pigging machine and accept the pigging machine.

                The valve body seal pair can withstand high temperature, high pressure, good corrosion resistance and long service life after special process treatment.

                Transmission mode: adopt worm wheel mechanism, easy and flexible operation.

                Clear medium: water, steam, oil, suitable temperature (c) -30-150

                Structural features and uses

                1. Manipulation saving: The ball is supported between the valve body and the valve cover, and lined with copper alloy sliding bearings with good self-lubrication and wear-reducing properties. The force between the ball and the valve seat is accurately controlled.

                2. Quick opening blind plate: the blind plate and the valve body are fitted with a toothed insert, which is easy to operate. The quick opening blind plate of the larger size valve is connected with the rocker arm hinge fixed on the valve body, so even the large size valve is easy to dismantle and install the quick opening blind plate.

                3. Fire-resistant structure: stop the ball and valve seat to form metal and metal seals after the elastic seal ring is burned out due to sudden heat and fire. High temperature graphite gaskets are provided between the valve body and the valve and the stem parts to ensure the sealing reliability at high temperature. The fire test meets the requirements of API6FA and AIP607 standards.

                4. Anti-static structure: In order to prevent static electricity caused by friction between ball and valve stem and medium or sealing ring, static electricity conducting spring and contacts are arranged between valve stem and ball and between valve stem and valve body, so that static electricity can be led underground through pipeline to ensure system safety.

                5. Interlocking structure: the relief valve and the quick opening blind plate lock interlock, in the relief valve has not opened to release pressure, can not open the blind plate. Ensure the safety of operation.

                6. Auxiliary Sealing Settings: This valve is equipped with auxiliary seat emergency sealing system. Once the seal is damaged or can not be sealed in emergency, the sealing surface can be repaired by injecting corresponding sealant into the sealing surface through the auxiliary sealing system to achieve emergency sealing. In order to protect the reliability of the sealing surface, the device can also be injected with the corresponding cleaning agent or lubricant to clean the sealing surface when the conveying medium is dirty or contains a small amount of particles.

                7. Cleaning: The valve body is equipped with a water injection valve, which flushes the body cavity of the valve through a water injection valve with a sprinkler when the toxic medium is transported, and puts it into the sewage tank through the sewage discharge valve.

                8, widely used in petroleum, chemical, oil, steam, natural gas, water and other media.

                Standard of execution

                1. Design and manufacture: ANSI B16.34; PDI6D.

                2. Test and test: g / T 13, 9 - 27 - 3; API598.

                3. Flange connection: ANSI / B16.5.
