Pneumatic discharge ball valve
Pneumatic discharge ball valve product introduction£º
Pneumatic discharge ball valve sealing ring with PPL wear-resisting sealing ring, make the seal durability.Using card sleeve connection between seat and body can block under the dust into the seat, avoid the seat was up to death.Suitable for long distance pipeline and general industrial pipeline, its strength, security, and resistance to bad environment, special consideration when the design is suitable for all kinds of corrosive and non corrosive medium.
The working principle of the pneumatic discharge ball valve£º
Pneumatic discharge ball valve, the valve fluid pressure produced in the sphere of action before all passed to bearing, won't make a sphere to the seat to move, so the seat will not bear too much pressure, all fixed ball valve torque is small, the seat of the small deformation, stable sealing performance, long service life, suitable for high pressure, large diameter pipeline.Advanced spring seat components, since the tight characteristics, realize the upstream sealing.Each valve has two seats, each direction can be sealed, and therefore there is no flow restriction, installation is two-way.This valve has two and three type two kinds of body structure, the flange bolting, seal enhanced ptfe inserted into the stainless steel ring, steel ring is equipped with a spring at the back of the guarantee the seat close to the ball, keep the seal.With ptfe valve stem up and down bearing, reduce friction, easy operation, small at the bottom of the shaft adjustment, to ensure that the ball and seal it.Adopt the structure of the full size valve flow aperture is consistent with the pipeline diameter, so that pipeline cleaning.
Characteristics of pneumatic discharge ball valve products£º
1, pneumatic discharge ball valve and seat with automatic compensation device, more reliable to ensure the ball valve sealing performance;
2, sealing ring of the use of special materials, high temperature resistance, wear resistance, long service life characteristics;
3, the valve stem adopts integral forging processing and modulation, hardness of hb220 ~ 250, the valve stem blow-out proof structure design, according to the need to lengthen the valve stem is used for buried place;
4, according to customer needs, the discharge ball valve can be designed as antistatic structure, in the sphere and valve stem, valve stem and valve body between the conductive spring, avoid electrostatic spark to ignite flammable material, ensure the security of the system.
5, sealing deputy various forms and can be chosen according to different working condition of soft seal and hard seal structure, the structure of the fire valve seat structure design;
6, according to the need can be installed on the auxiliary seal structure, the valve seat and valve rod parts add fat injection valve, an emergency can be temporarily sealed;
7, pneumatic discharge ball valve has a valve structure is compact, easy and convenient installation and maintenance, etc.
