The characteristics of ball valves

Author:


A; Wear resistance; Because the SPool OF THE hard seal ball VALVE IS sprayed BY alloy steel, AND the sealing ring of the three-piece ball valve is SURFACING by alloy steel, the hard seal ball valve will not produce too much wear when switching on and off. (Its hardness coefficient is 65-70):

2. Good sealing performance; Because the seal of the hard seal ball valve is manually ground, until the spool and the sealing ring can be used completely. So his sealing performance is reliable.

Three; Light switch; Due to the spring at the bottom of the sealing ring of the hard seal ball valve, the sealing ring and the valve core are tightly held together, so the switch is very light when the external force exceeds the preloading force of the spring.

Four; Long service life: has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rocket and other departments, as well as People's Daily life.

Pneumatic ball valve structure is compact, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, and is suitable for water, solvents, acids and generally working medium, such as natural gas is mainly used for cutting or on line in the medium, can also be used to adjust and control of the fluid.

Pneumatic ball valve compared with other types of valves, with angular stroke output torque, rapid opening, stable and reliable, widely applicable, such as the following advantages.

1, the thrust bearing reduces the friction torque of the valve stem, can make the long-term operation of the valve stem smooth and flexible.

2, anti-static function: the spring is set between the ball, valve stem and valve body, which can export the static electricity generated by the switching process.

3, because PTFE and other materials have good self-lubricity, friction loss with the ball is small, so the service life of the pneumatic ball valve is long.

4, fluid resistance is small: pneumatic ball valve is one of the least fluid resistance in all valve categories, even reduced diameter pneumatic ball valve, its fluid resistance is quite small.

5, the stem seal is reliable: because the stem is only as if rotating transport without lifting movement, the stem packing seal is not easy to destroy, and the sealing ability increases with the pressure of the medium.

6, the seat sealing performance is good: the use of PTFE and other elastic materials made of the sealing ring, the structure is easy to seal, and the sealing capacity of the pneumatic ball valve increases with the increase of the medium pressure.
