National standard manual pneumatic valve flange stainless steel ball Q41F - 16页

QF - P: stainless steel ball pneumatic valve, pneumatic valve has simple structure, small volume, light weight, small flow resistance, good energy saving effect, the medium flows through the pneumatic valve, equivalent to flow through a straight pipe, the fluid resistance minimum, fluid into and out of the pneumatic valve direction can be arbitrary choice, has a two-way role. Q type fixed pneumatic ball valve compared with the floating ball pneumatic valve, it is working, pneumatic valve fluid pressure produced in the sphere of action before all passed to bearing, won't make a sphere to the mobile pneumatic valve seat, and pneumatic seat can't under too much pressure, so the stationary small torque of pneumatic valve, pneumatic ball seat small deformation, stable sealing performance, long service life, applicable to high pressure, large diameter. Advanced springs in pneumatic seat components, since the tight characteristics, realize the upstream sealing. Each pneumatic valve has two pneumatic valve seat, each direction can be sealed, and therefore there is no flow limit installation. Is a new generation of high-performance pneumatic ball valve, flange fixed pneumatic ball valve is 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. , working principle of the

flange fixed pneumatic valve ball ball is fixed, connected by two segments and sphere fixed shaft support. Closed, under the action of medium pressure, the ball will not produce displacement, often connected with sphere, the shaft is equipped with rolling bearings, or sliding bearing. In order to reduce the friction when opening and closing journal. Reduce operating torque. The fixed pneumatic ball valve is suitable for large diameter ball pneumatic valve. Q hard seal fixed ball sphere of pneumatic valve. The upper and lower two pneumatic valve rod fixation. Work, doesn't make the ball to the pneumatic seat moving fluid pressure, pneumatic seat won't under too much pressure and deformation. Pneumatic valve stem section with self-lubricating bearings, reducing friction, switching torque is small, pneumatic valve seat adopts two spring preload. Sealing using ptfe inserted into the steel, steel ring at the back is equipped with spring, ensure pneumatic seat close to the sphere. When pneumatic valve lumen abnormal pressure higher than spring tension, pneumatic seat back out of the sphere, achieve automatic relief effect, pressure pneumatic seat after automatic reset. Structure is so sophisticated that fixed pneumatic ball valve sealing performance and stable operation of saving, service life is long, very suitable for long distance pipeline and pipeline.
product features:
, adopt fixed ball design, relative motion parts adopt minimum friction coefficient self-lubrication material, and operating torque is small, moreover sealing grease seal for a long time, make the operation more flexible.
high platform structure, pneumatic valve, ISO connection standard, can make the installation of electric/pneumatic actuator is more professional.
and using full size or reducing design, small flow resistance.
pneumatic valve, metal hard seal O stationary ball structure of metal movable sealing in both directions, with functions of automatic compensation and self-cleaning, sealed performance is superior.
and adopt fixed ball design, and increased the pre-tightening force of spring, the pneumatic ball valve with functions of automatic pressure release.
every ball, pneumatic valve, there are two movable seal seat can sealing in both directions, and install need not consider the flow of medium.
, have fire retardant anti-static structure, in the pneumatic valve stem and valve body and pneumatic valve stem and ball set between the conductive spring, avoid electrostatic spark to ignite flammable medium. Ensure the security of the system.
double protection, the structure of the refractory, when one thousand a fire and make the seal loss, all sealing parts of pneumatic ball valve can form the metal to metal hard seal structure.
and automatic pressure relief structure, when the stranded in liquid medium of pneumatic valve lumen due to temperature gasification, and lumen abnormal pressure rises, the midplane medium can rely on itself thrust to promote pneumatic seat and automatic relief, so as to ensure the security of the pneumatic valve.
, optional pneumatic, electric, hydraulic, and pneumatic external regulation, electric external regulation. Pneumatic valve actuator and regulate specific please refer to the book. Pieces
