进口高温弹性座三偏心蝶阀Product Description:

The utility model comprises a valve body, a butterfly plate, an upper valve shaft and a lower valve shaft. The upper valve shaft is arranged at the inlet end of the valve body, the lower valve shaft is arranged at the outlet end of the valve body, the butterfly plate is arranged in the valve body, the butterfly plate is sealed through the J-shaped valve seat, the bending section of the J-shaped valve seat is matched and sealed with the side of the butterfly plate, and its long end is pressed and fixed through the valve seat pressing ring. The sealing surface of the J-shaped valve seat is a three eccentric structure and elastic, and a support ring is arranged in the valve body, The support ring is provided with a fixing device, which contacts the valve seat pressure ring and compresses the valve seat pressure ring. The sealing pair is made of all metal material, which has high temperature resistance and is not easy to be damaged; Moreover, a compensation structure is set, and the valve can be opened if the sealing pair is damaged.

进口高温弹性座三偏心蝶阀characteristic:

High temperature medium pipeline butterfly valve is mainly composed of three eccentric structure of metal graphite sealing ring and two eccentric structure of rigid metal sealing ring. The three eccentric structure of metal graphite sealing ring is composed of graphite with low hardness, fragile and poor compensation performance, while the two eccentric structure of rigid metal sealing ring still has relative friction and wear, and the metal ring is rigid structure without compensation performance, The above two structures are easy to damage the sealing pair and the valve cannot be sealed after long-term use.
