The check valve which has the characteristics of yourself? Check valve is a kind of technical performance has strong valve, in many different industries have a very good use, for enterprise's production management provides a lot of convenience, the following is our understanding of the features of it together. Pneumatic Industrial Valves disc sliding along the center line of the body of the valve. Pipeline check valve is a new kind of valve, its small size, light in weight and good processing technology, is one of the check valve development direction. But the fluid drag coefficient is slightly superior to swing check valves. Check valve disc around the seat to the clamp pin shaft rotate within the check valve. Disc check valve has simple structure, can only be installed in horizontal pipe runs, sealing is good. Swing check valve can also be used to give the pressure could rise to more than the system pressure of the secondary system supply piping. Check Industrial Valves is compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, suitable for water, solvents, acids and generally working medium, such as natural gas is mainly used to cut off or connect pipe medium, can also be used for flow regulation and control. 。 Check valve characteristic analysis, wear-resisting, due to the hard seal ball valve is the core of alloy spray welding, sealing ring is alloy steel welding, so the switch of the hard sealing ball valve is no wear and tear. 。 Sealing performance is good, as a result of the hard sealing ball valve seal is manual grinding, until the valve core and seal completely matching to use. So he sealed performance is reliable. Switch light, due to the hard seal ball valve at the bottom of the sealing ring springs, sealing ring and Industrial Valves core fit closely, so when the external force than spring pre-tightening force, switch is very light. 。 Stem seal reliable: as the stem just by leverage, don't lift, not break, so the valve stem packing seal sealing ability with medium pressure increases. 。 Seat sealing performance is good, use the sealing ring made of elastic material, such as teflon structure easy to seal, valve check valve sealing ability increases with the increase of medium voltage. 。 Anti-static function: ball, valve stem, valve body between spring, in the process of the output switch static electricity. 。 Due to the good self-lubrication, ptfe, small friction loss of the ball, pneumatic ball valve of long service life. Fluid resistance is small, the check valve are classified all valves fluid resistance is small. 。 So the advantage of the check valve is very obvious, it is in order to people can be a good choice, production enterprises offer a lot of convenience for people.
