Introduction the Shortcomings of gate valve

     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, square I-shaped gate valve sealing surface to form two wedge, wedge angle varies with the valve parameters, usually 5 °, medium temperature is not high to 2 ° 52'.To improve the process of the deviation, make up the sealing surface angle in the process, this gate is called the flexible gate.

    Shortcomings

      Disadvantages: between the sealing surface can lead to erosion and abrasion, repair is difficult. The large dimensions, requires a certain open space, opening and closing a long time. Complex structure.

Valve types, according to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate valve can be divided into single gate type, dual gate plate. 

      Classified according to location of threaded stem, can be divided into the next shot and the dark bar gate valve two.

Agricultural Chain

      Structural features: the market has long been used byThe general prevalence of valve Water Leakage or rustphenomenon, the introduction of European enterprises in rubber and valve manufacturing technology produced by the elastic valve seat seal, the valve seal bad, rust and other defects, elastic valve seat seal using flexible wedge generated trace elastic deformationcompensation function to achieve a good seal, the valve has a light switch, reliable sealing, good elastic memory and life and other significant advantages.

      Can be widely used for water, sewage,construction, petroleum, chemical industry, food, pharmaceutical,textile, electric power, shipbuilding, metallurgy, energy systems,body pipeline regulation and closure devices as.
