The junction of ring, main valve body and pressure ring is provided with sealing ring, and the side of sealing ring is provided with limit valve seat, the bottom end setting of pressure ring
There is spring, the junction for limiting valve seat and sealing ring is provided with thrust pad, and the side far from main valve body offers on the sphere
Escape orifice.
As a further solution of the present invention: the thrust pad is concave structure, and groove is provided on thrust pad.
As further scheme of the invention: the pressure ring is wedge structure.
As further scheme of the invention: offering the first limit hole corresponding with spring on the main valve body.
Compared with prior art, the beneficial effects of the present invention are: escape orifice is provided on the sphere of side, in balanced valve
The pressure of chamber, the generation of adiabatic compression when valve being avoided to open, secondly, being arranged on sealing Special ball valve for oxygen valve seat construction firmly
The back side design of gasket, sealing ring has thrust pad, and the position of the thrust pad and limit valve seat rear-face contact is designed to concave surface,
And a certain number of grooves are processed, so that facilitating pressure medium preferably enters the limit valve seat back side, effectively improve limit
The pretightning force of position valve seat.
