Product Description

Ball valve
Ball valve, ball valve in the field of Marine engineering and ship should stop valve), the standard of GB/T21465-2008 "valve terms" is defined as: opening and closing (sphere) driven by the valve stem, and around the axis of rotation movement of the valve stem.Use can also be used on regulation and control of fluid, the "V" ball valve, hard seal the v-shaped ball core of carbide surfacing with strong shear force between metal valve seat, especially suitable for fiber, micro solid material such as medium.And ball valve in the pipeline is not only more connected to the confluence of flexible control medium, shunt, and the flow switch, at the same time also can close any channel and make the other two.This valve shall generally be installed in the pipeline.Classification of ball valve, pneumatic ball valves, electric ball valves, manual ball valve.

advantages


1. The fluid resistance is small, little flow resistance full size of ball valve.


2. Simple structure, small volume, light weight.


3. Compact and reliable.It has two sealing surface, and the widely use of all kinds of plastic ball valve sealing surface of materials, good sealing, can realize completely sealed.Have been widely used in the vacuum system.


4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.


5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.


6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause valve sealing surface erosion.


7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.


8.) wipe because of ball valves in the process of opening and closing and so can be used to bring in the medium of suspended solid particles.


disadvantages


High machining precision, expensive and difficult to use in high temperature, such as pipe contains impurities, easily blocked by impurities, lead to valve cannot open


According to the feature classification


1, by-pass valve, ball valve, generally for hydrostatic open, so set a by-pass valve flat first, that is filled with water on both sides;


2, air valve, water filling, exclude air taking buoy to close the valve;Drainage, complement with air, buoy from falling;


3, the pressure relief valve: open shutoff valve, eliminate between valve and plug the pressure of the water, so as not to wear sealing cover;


4, drain valve, discharge a sewage at the bottom of the ball inside the shell.


According to the classification of transmission mechanism


1, pneumatic ball valve


2, electric ball valves


3, hydraulic ball valve


4, hydraulic ball valve


5, electric hydraulic ball valves


6, turbine drive ball valve
