Depart from, prevent sealing surface friction, it is ensured that sealing property；In the same manner, during valve closing, initial period valve seat and spheroid are without connecing
Touch, only rear valve base is closed in pilot valve and just can overcome spring force in the presence of medium power so that valve seat is fitted with spheroid, realized
Sealing.
2nd, stem bottom is set to into cam structure further, is engaged with the axis hole on spheroid, just starts in valve rod
During rotation, valve rod rotation drives spheroid to rotate together after α angles are turned over again, and during valve rod rotation α angles, valve rod is same
When promote the push rod of pilot valve that pilot valve is opened, realize lumen pressure release so that valve seat and spheroid depart from, so as to realize valve
The frictionless motion of opening process；In the same manner, during valve closing, valve seat is contactless with spheroid, until valve is closed in place
Valve rod rotation afterwards, while pilot valve is closed, medium is pushed dynamic valve seat and is fitted with spheroid, realizes sealing.
The 3rd, valve seat is further set to split type, the i.e. form of inner ring valve seat and outer ring valve seat, inner ring valve seat
Sealing surface is for nonmetallic, and inner ring valve seat contact with spheroid during valve opening and closing all the time, effectively trickle in prevention medium
Granule is entered in the metallic sealing section of outer ring valve seat, prevents metallic sealing section from abrasion occurring, while being also beneficial to runner cavity
Inside overstock.
