C-shaped hemisphere valve
C hemisphere valve is Lianda according to the special conditions of a hemisphere design, a single seat of a one-way ball valve, the valve without closed valve cavity, can solve in the coal water slurry black water ash water system, solid medium tank bottom discharging system, easy to scale / crystallization solution slurry, slurry ash, polycrystalline silicon process, easy to be in the medium in the valve cavity accumulation or scaling cause valve leakage or death.
1. Polypropylene feed and discharge valve
2. Discharge valve of centrifuge
3. vacuum valve
4. Vacuum dryer, feed and discharge valve
1. anti-scouring
2. Prevent cavities from scaling
3. full diameter can pass through the ball pig
4. Zero leakage can be achieved
5. Low switching torque
6. fire-protection design
Structural Characteristics
Instructions
Long bearing design
the valve shaft and fixed shaft are equipped with high quality self-lubricating wear-resistant long bearing, which can keep the valve shaft co-axial and eliminate the load caused by the valve switch or valve vibration.
Scratcher design
in order to prevent the adhesion structure of the attached medium caused by valve tightness or leakage, we will do scraper design at the valve seat seal, and the switch process can be used to clean the sphere
Bearing cavity sealing design
the upper and lower bearing cavity is designed with a sealing structure to prevent the torque of the valve or the solid medium entering the bearing cavity.
Anti-blowing valve stem
adopt high corrosion resistance super alloy, and conduct vacuum heat treatment to improve the surface hardness and prevent strain. Upper packing function structure to prevent the stem from blowing out.
packing loading and sealing
the packing place adopts the disc spring loading design, and the long-term sealing is more reliable.
Design of wear-resistant bushing
the flow hole is equipped with the wear-resistant bushing of jet-welded hard alloy, which well responds to the long-term erosion of the medium and prevents fine impurities from entering the spring cavity, leading to spring failure. Wear-resistant bushing is replaceable structure, later maintenance is more convenient.
External leakage point seal
middle flange, lower fixed shaft, upper packing letter using metal hard to hard, metal winding pad, O-ring and other multiple seals, can also be sealed in the case of fire, the seal is more reliable.
