进口三偏心高性能球阀美国阿卡迪亚品牌

进口三偏心高性能球阀Product Description:

It consists of support shaft, valve body, valve seat, valve core, valve stem, valve cover, packing device and driving device. The valve core is installed in the center of the valve body with the left and right offset distance a of 1-5mm, and the front and rear offset distance b of 1-7mm. It forms an angle with the valve seat after sealing β 5 ～ 15 °; The support shaft is located in the support groove at the bottom of the valve core, and a steel seal ring is arranged between the support shaft and the valve core support groove; The valve seat is fixed on the valve body by bolts; The valve cover is installed at the top of the valve body, and is locked and sealed by the gland of the packing device; The valve stem is located on the support groove of the top valve element and is connected with the packing device and the driving device through the valve cover; The valve core includes a sealing gasket, a spherical sealing block, a sealing pressure block and a valve core support groove. The structure is simple, and it can be stably and reliably used in viscous granular media such as particles, powder or coal slurry, reducing the wear dead zone of the valve sealing surface and extending the service life of the valve.

进口三偏心高性能球阀characteristic:

The accumulation of particles around the moving parts of mixed media containing sand, powder, solid particles or mud will cause erosion of the valve internals and accelerate the damage of the valve internals. Due to the similar movement structure, the metal sealed ball valve or gate valve is not designed to meet the requirements of powder and particle grinding. Although the rail ball valve can meet the requirements of working conditions, the lifting valve stem adopts forced sealing, which causes serious wear between the valve stem and the guide pin and high maintenance costs in the later period. The failure of the valve is often due to insufficient estimation of the erosion of the moving parts of the valve caused by the grinding of solid particles. When the valve is working, the fluid erosion + the accumulation of grinding medium in the "dead zone" will cause the failure of ordinary ball spring and the wear of valve seat and ball sealing surface.

进口三偏心高性能球阀Principle:

Three eccentric high-performance C-type ball valve, including support shaft, valve body, valve seat, valve core, valve stem, valve cover, packing device and driving device. The valve core is installed in the center of the valve body, with the left and right offset distance a of 1-5mm, and the front and rear offset distance b of 1-7mm. It forms an angle with the valve seat after sealing β 5 ～ 15 °; The support shaft is located in the support groove at the bottom of the valve core, and a steel sealing ring is arranged between the support shaft and the valve core support groove; The valve seat is fixed on the valve body by bolts; The valve cover is installed at the top of the valve body, and is locked and sealed by the gland of the packing device; The valve stem is located on the support groove of the top valve element and is connected with the packing device and the driving device through the valve cover; The valve core comprises a sealing gasket, a spherical sealing block, a sealing pressure block and a valve core support groove.
