Valve is the use of the gate as a headstock, through the valve stem up and down to drive the gate lifting to achieve the opening and closing of the valve, gate movement and fluid direction perpendicular to the direction, gate valve can only be fully open and fully closed, can not to regulate and reduce expenditure. Are suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other medium.
The inlet gate market press materials for the import of steel gate valve, imports of iron gate, imports of stainless steel gate valve;
According to the standards can be imported into American standard gate valve and imports of Japanese standard gate valve;
According to the connection mode can be divided into internal thread of forged steel valve imports and imports of high temperature pressure power station gate valves ( welding gate );
Also according to the valve plate structure, used for slurry, coal, mine pulp imports valve and imports of pneumatic valve, used in petroleum drilling and other import flat gate valve;
Special valve market is also used in water using imported elastic seat sealing gate valve, used in cryogenic liquid natural gas, cryogenic liquid oxygen by Cryogenic Gate Valves, used in asphalt, conducting oil and other imports with thermal insulation jacket insulation valve.
China Gate advantages
In 1, small flow resistance. China Import gate valve body within the media channel is straight, medium into a straight flow, small flow resistance.
2, gate valves open and close when more effort. Because whether it is open or closed, the gate movement direction perpendicular to the flow direction with the medium.
3, gate height is large, open and close a long time. The gate opening and closing stroke larger, descending through the screw rod.
In 4, valve closure time is long, not easy generation of water hammer phenomenon.
5, gate valves on both sides of the channel is symmetrical, medium to flow at any direction, easy to install, no limitation of direction.
China gate will be more widely used in water conservancy, machinery, paper making, metallurgy, petrochemical, chemical, construction and other industries.
