Developed combined with domestic actual plunger valve is factory, its design and manufacturing is in order to solve the flaws of the normal cut-off valve, packing standard globe valve seal USES billet root, cannot be ruled out leakage phenomenon, sealed by the disc and body under plane Angle or seal (metal seal), sealing surface leakage caused by the wear between the metal, and maintenance difficulties; The closure of the plunger valve is composed of a stainless steel plunger, two upper and lower elastic sealing rings and a metal spacer. The sealing effect is achieved by the plunger and the sealing ring working closely together. The plunger is inserted in the two sealing rings, and the sealing area is much larger than the ordinary globe valve. When switching the plunger valve, the plunger moves slowly in the sealing ring with little wear on the contact surface. When opened, although the plunger is separated from the lower sealing ring, it is still hidden in the upper sealing ring to keep isolated from the outside world and avoid leakage.
Seal ring is a technology product, is the key parts of the plunger valve, it is composed of ptfe, graphite, high elastic adhesive, etc.
Product features:
Internal thread connecting plunger valve is divided into non-metallic seal, metal seal two categories, in addition, external thread connecting plunger valve shape is divided into Z shape and drum shape two categories, its internal structure is exactly the same, the same purpose, mainly used in metallurgy, electrical industry, chemical industry, oil refining, food and other industries. Pressure within 16-25kgf/cm2, temperature below 250℃ water, steam, oil and other small diameter pipe for opening and closing for regulating flow.
Scope of use: the product can be used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other industries under various working conditions in the pipeline, cut off or put through the pipeline medium.
