Introduction of internal thread ball valve

Threaded ball valve butt welding ball valve is divided into integral (one piece), two-stage and three-stage. The valve body casting adopts the advanced technology introduced from Taiwan, with reasonable structure and beautiful appearance. The valve seat adopts elastic sealing structure, reliable sealing and easy opening and closing. The valve stem adopts a bottom mounted structure with inverted seal, so the valve stem will not be flushed out when the valve chamber is abnormally pressurized. Two piece and three piece ball valves are connected by butt welding (BW) and socket welding (SW), and can be equipped with international standard ISO support platform and locking device. The 90 ° switch positioning mechanism can be set, which can be locked according to the need to prevent misoperation. The driving mode is manual, electric and pneumatic.

Application scope:

The internal thread ball valve and butt welding ball valve are suitable for various pipelines with PN1.0 ~ 4.0Mpa, working temperature - 29 ~ 180 ℃ (the sealing ring is reinforced polytetrafluoroethylene) or - 29 ~ 300 ℃ (the sealing ring is para polyphenylene) to cut off or connect the medium in the pipeline. Different materials can be used for water, gas, steam, oil, nitric acid, acetic acid and other media.

Structural features:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe. 2. Simple structure, small volume and light weight. 3. It is tight and reliable. At present, the sealing surface material of ball valve is widely made of plastic with good sealing performance, and it has been widely used in vacuum system. 4. Convenient operation, fast opening and closing, from full opening to full closing as long as 90 ° rotation, convenient for remote control. 5. Easy maintenance, simple structure of ball valve, movable sealing ring, easy disassembly and replacement. 6. When the valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause the erosion of the valve sealing surface. 7. Wide range of application, diameter from small to several millimeters, to several meters, from high vacuum to high pressure can be applied.
