Rubber o-ring.
Preferably, the valve rod is an integral molding structure with valve ball, and is offered at valve rod position corresponding with ball
One circle groove.
Compared with prior art, the beneficial effects of the present invention are: the panel of the easy structure installs high-pressure ball valve, pass through rotation
Turn pressure cap, moves down pressure cap on boss, so that airtight and watertight padding is squeezed, the progress level side when airtight and watertight padding is under pressure
To expansion, make airtight and watertight padding with the outer wall of valve rod is closer is bonded, further improve leakproofness, extend airtight and watertight padding
Service life further prevents ball valve leak occur, while the limiting device being arranged can limit valve rod, prevent from revolving
Valve rod horizontal-shift is caused when rotating valve rod, is avoided the abrasion of airtight and watertight padding from aggravating, is extended the service life of high-pressure ball valve.
Detailed description of the invention
