Oxygen Ball Valve
Oxygen has strong oxidation, in the ultra-high purity oxygen system, if there are particles or pollutants collision, or friction arc, easy to cause combustion or even explosion. Therefore, in strict accordance with the domestic and foreign oxygen valve standards for rigorous design, strict control of the valve material selection, sealing test, strength test, electrostatic test, life test, roughness and cleanliness inspection, to ensure the reliable use of the valve.
1. Reliable sealing
2. Long service life
3. The valve flow channel light finish is small
4. Strictly ban oil treatment
5. Low switching torque
6. fire-protection design
7. Anti-static design
Structural Characteristics
Instructions
Filler loading sealing
the packing is imported degreasing flexible graphite, the packing is the disc spring loading design, the long-term sealing is more reliable.
Reasonable selection of sealing ring material
all seals are sealed with degreasing graphite, graphite has good electrical conductivity, thermal conductivity, fire prevention function, very suitable for pure oxygen conditions.
The roughness of the flow channel is small
the position of the medium flow, strictly control the surface finish in the processing, completely remove all the welding slag, oxidation skin, attachments, rust on the surface, to prevent impurities from collision and fire in oxygen
Long service life
the use of special carbide powder for supersonic jet welding, has high binding force, hardness and good self-lubrication, heat dissipation, solves the problems of metal bonding and strain caused by dry friction of the sealing surface in pure oxygen environment, and greatly improves the service life of the valve.
Design of the sphere vent
a drain hole is provided on one side of the sphere to balance the pressure of the cavity in the valve and avoid the generation of adiabatic compression when the valve is opened.
Strict oil ban measures
all parts of the valve are degreasing in strict accordance with the degreasing process, and can be assembled only after ultraviolet light test and strip wiping test. Dry and pure nitrogen should be used as the valve test medium.
Small switch torque
there are wear-resistant sliding bearings between the ball and the support plate and between the stem and the packing function, which reduces the switch torque of the valve.
Anti-static design
all parts of the valve have metal to metal contact, and the flange in the valve is equipped with conductive grounding bolts to prevent static electricity accumulation and fire.
