1. All parts are forgings
2. Lower mounted valve stem and inverted sealing structure of equipment are adopted
3. The use of Mosaic valve seat, seat back equipment O ring, to ensure that the medium leakage
4. The sealing surface use nylon,PTFE,Delvon,PEEK or metal seat for good performance and long service life.
5. Suitable for chemical industry, petroleum, natural gas, metallurgy and other industries and hydrogen sulfide medium, impurities, corrosion severe long - term natural gas pipeline.
1 The structure is simple, the weight and volume are relatively small, and it is easy to disassemble and repair.
2 Since the valve stem only rotates, the packing seal of the valve stem is not easily broken, and the sealing capacity
increases as the medium pressure increases.
3 The fluid resistance is small, and the full-bore ball valve has substantially no flow resistance. Pneumatic ball valves are one of the least fluid resistances in all valve classifications.
4 The operation is simple and rapid, and it only needs to be rotated by 90° from full opening to full closing, which is convenient for long-distance control.
5 It is suitable for a wide range of applications, from a few millimeters to a few meters, from high vacuum to high pressure.
The principle of the fire-proof structure of the valve seat is that, the ball valve adopts a double seal design. When the soft seal is melted due to high temperature, the valve core ball is redesigned to form a right-angle hard seal with the soft seal behind, forming a sealing relationship again.
The metal sealing surface on the valve seat only acts as a temporary seal. Although the sealing requirements are not too strict, there are still certain processing requirements that should be processed into spherical or inclined surfaces. If it is made into a spherical surface, its radius of curvature should be the same as that of the sphere, and the edges and corners of the sealing surface should be rounded to avoid damage to the smoothness of the sealing surface on the surface of the sphere during assembly and disassembly.
When the fireproof and anti-static ball valve is opened and closed, friction will occur between the ball and the valve seat, and the static electricity generated by the friction will accumulate on the ball. Ball valves used on gas, fuel and chemical lines do not allow this. , may cause a pipeline explosion accident. The anti-static structure of the ball valve is equipped with an electrostatic discharge device, which can export the electrostatic charge accumulated in the ball at the first time, effectively ensuring the safe operation of the pipeline.
