彈性座封閘閥The elastic valve seat seal
Resilient seated gate valve is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Dark bar elastic valve seat seal with the valve plastic deformation the overall compensation package to achieve a good seal, valve seal to overcome the generally poor, Water Leakage and rusty phenomenon, saving installation space more effectively. Elastic seat sealing soft sealing gate valve can be widely used for fluid pipelines of tap water, sewage, construction, petroleum, chemical industry, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy system as a regulator and the closure device.
Scope of application: flexible seat seal gate valve is especially suitable for drinking water system, food and pharmaceutical industry, industrial water supply and sewage treatment, natural gas and coal gas, soft sealing gate valve can be widely used for fluid pipelines of tap water, sewage, construction, petroleum, chemical industry, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy system and so on.
Structure features: flat style seat Yongjia valve supply network company soft sealing gate valve at the bottom of the use of the whole basin straight channel design, equivalent to the straight pipe, no stagnant cavity structure, small flow resistance, to ensure that the fluid flow is not easy to deposit, debris, will not cause secondary pollution to the media two.
Fully coated gate gate made of ductile iron QT500-7 framework covering high performance rubber, vulcanized mature technology and advanced vulcanization process, complete the gate core and fluid isolation. Coating is compact and reliable, its combination of strength meet the requirements of DVGW, even by the frequent extrusion stress rubber does not drop. The valve stem nut and the two type structure, ensure sufficient freedom, flexible opening and closing no jamming.
Online replace sealing ring special seal structure, the fully open to online is not supplied replace sealing ring;
Reliable seal between the stem and cap seal, the "3 and 2" Five "O" type sealing ring structure, compared with the traditional gate valve packing seal structure, seal tightly and reliably, the friction resistance is greatly reduced.
Anticorrosion performance of shell (ductile iron QT500-7) epoxy resin powder electrostatic spray coating surface, uniform and firm, not dew iron; cavity connecting bolt top sealing glue, isolate the bolt contact with the environment, in order to prevent corrosion.
