【 Product Features 】
1, its structure adopts the eccentric tightening principle through the transmission mechanism to achieve the purpose of brake tightening, adjustment and closure, the sealing pair is a metal surface ring with a hard surface contact seal, double eccentric structure in the opening of the valve spool is located in the ball room, the flow section is large, and the valve is not washed, the valve spool is not washed when closed, the valve spool ball is gradually along the valve seat when opened, effectively cutting the scale barrier. Achieve reliable sealing. It is especially effective for two-phase mixed flow transportation where solid precipitates are easy to scale
2, the hemisphere of the valve with bimetal, the base metal on the surfacing of different alloys, the valve seat is also the corresponding surfacing welding by special treatment, sealing surface combination into anti-corrosion, wear, high strength and other types to meet the needs of different occasions
3, tight seal, transport harmful gas can reach zero leakage
4, the valve core of the sealing pair has a compensation amount, when the valve is worn, it is turned a little when it is closed, and it can be reliably sealed and extend the service life. In addition, the user will screw off the compression nut, adjust or replace the valve seat is still available, to avoid the failure of the valve seal, the whole set scrapped
Due to surfacing welding different alloy (or combination ball) bimetal sealing pair selection can be used for wear resistance, corrosion resistance, high temperature resistance and strict sealing conditions
1, general valve: specification model DN40-1600. It is suitable for sewage treatment, paper pulp, urban heating and other tight occasions
2. Special valve for petrochemical industry: specification DN40-1600. Suitable for crude oil, heavy oil and other oil products, chemical industry weak corrosion, two-phase mixed flow medium
3, gas special valve: specification DN40-1600. Suitable for gas, natural gas, liquefied gas transmission control
4, slurry special valve: specification DN40-1600. It is suitable for liquid and solid two-phase mixed flow or industrial pipeline transportation with crystallization or scaling in chemical reaction of liquid transportation
5. Special valve for pulverized coal ash: specification DN40-1600. Suitable for power plant, hydraulic slag removal or gas pipeline control
Q347 type PN16, PN25 eccentric half ball valve using eccentric valve body, eccentric ball and seat, the valve stem for rotating movement in the common track automatic centering, closing process tighter, fully achieve a good sealing purpose. The ball and seat of the valve are completely separated, eliminating the wear of the seal ring, overcoming the problem that the traditional ball seat and the ball sealing surface are always worn, non-metallic elastic materials are embedded in the metal seat, and the metal surface of the seat is well protected. This product is especially suitable for steel industry, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas and other media
