Double eccentric semi-ball valve (PQ340H, PQ340Y, PQ340F) ball valve opening and closing parts
Double eccentric semi-ball valve (PQ340H, PQ340Y, PQ340F) ball valve opening and closing parts (ball) driven by the valve stem, and around the ball valve axis for rotating movement of the valve. Can also be used for fluid regulation and control, including hard seal V-shaped ball valve of its V-shaped ball core and hard alloy surfacing metal valve seat has a strong shear force, especially suitable for containing fiber, small solid particles and other media. The multi-way ball valve in the pipeline can not only flexibly control the convergence of media, diversion, and flow switching, but also can close any channel to connect the other two channels. This type of valve in the pipeline should generally be installed horizontally. Ball valve according to the driving mode is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
Features of double eccentric half ball valve
The 1. is wear-resistant; because the valve core of the hard seal ball valve is alloy steel spray welding, and the sealing ring is alloy steel surfacing welding, the hard seal ball valve will not produce too much wear when switching. (Its hardness coefficient is 65-70);
2. sealing performance is good; due to the hard seal ball valve is the use of artificial grinding, until the valve core and seal ring completely consistent to use. So his sealing performance is reliable.
The 3. switch is light; because the sealing ring of the hard seal ball valve uses a spring at the bottom to hold the sealing ring tightly with the valve core, the switch is very light when the external force exceeds the preload of the spring.
Long service life of the 4.: it has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily life.
