Q41F-16P stainless steel ball valve: 1, the valve structure is simple, small size, light weight, small flow resistance, energy-saving effect, the medium flow through the valve, the equivalent of flowing through a section of the pipeline, the minimum fluid resistance 2, , Out of the valve direction can be arbitrarily selected, with a two-way effect. Q47 type fixed ball valve It is compared with the floating ball valve, work, the valve fluid pressure in front of the ball on the force generated by all transmitted to the bearing will not move the ball to the seat, so the seat will not be subjected to excessive pressure , So the fixed ball valve torque is small, valve seat deformation is small, stable sealing performance, long service life, suitable for high pressure, large diameter occasions. Advanced spring pre-seat assembly with self-tightening features for upstream sealing. Each valve has two seats, sealed in all directions, so there is no flow restriction on the installation. Is a new generation of high-performance ball valve, flange fixed ball valve for long-distance pipelines and general industrial pipelines, its strength, safety, resistance to harsh environments in the design of special consideration for a variety of corrosive and non-corrosive Sexual media.
working principle:
Flange fixed ball valve ball is fixed by the two connected with the ball fixed shaft support. When closed, under the action of medium pressure, the ball will not be displaced. Usually, the upper and lower shafts connected with the ball are equipped with rolling bearings or sliding bearings. To reduce the opening and closing of the journal friction. Reduce the operating torque. This fixed ball valve for large-diameter ball valve. Q47 hard seal fixed ball valve ball. Using the upper and lower two stem fixed. Work, the fluid pressure will not move the ball to the seat, seat will not withstand excessive pressure and deformation. Stem part with a self-lubricating bearings to reduce friction, the switch torque is small, the two valve seat spring preload. Teflon sealed with steel seal, the rear of the ring with a spring to ensure that the valve seat close to the ball. When the valve cavity pressure abnormal rise over the top of the spring force, the seat back from the ball, to achieve the effect of automatic relief, pressure seat automatically reset. The advanced structure of the fixed ball valve seal performance stable operation, effort, long life, very suitable for long-distance pipeline and general pipeline.
Features:
1, the use of fixed ball design, the relative motion of the friction coefficient is a very small self-lubricating material, so the operating torque is small, in addition to long-term sealed grease seal, making the operation more flexible.
2, the valve adopts high platform structure, ISO5211 connection standard, can make the installation of electric / pneumatic actuator more specialized.
3, the use of full diameter or reduced diameter design, circulation resistance is small.
4, metal seal O-type fixed ball valve with two-way metal movable seal structure, with automatic compensation and self-cleaning function, superior sealing performance.
5, using a fixed ball design, and increased the preload spring, making the ball valve with automatic pressure relief function.
6, Each ball valve has two movable seal seat, both directions can be sealed, so do not need to consider the installation of media flow.
7, with fire and anti-static structure, the valve stem and the valve stem and the sphere set between the conductive spring, to avoid electrostatic ignition ignite flammable media. Make sure the system is safe.
8, double protection of fire-resistant structure, in case of fire and seal ring burning, the ball valve seal parts can form a metal-to-metal seal structure.
9, automatic pressure relief structure, when the liquid trapped in the valve chamber cavity gasification due to temperature rise, so the cavity pressure anomalies, the cavity medium can rely on its own thrust to promote the valve seat and automatically relief to Make sure the valve is safe.
10, optional pneumatic, electric, hydraulic, and pneumatic regulation, electric regulation type. For details, please refer to the book Actuator and control valve section.
