When turning, intermediate lift sleeve then corresponds to and declines or rise, so as to closing or opening stop valve.
Used as optimal technical scheme of the present utility model, the cut-off pressing plate includes metal expelling the toxic substance from the body with tonic and elastic press, described
Metal expelling the toxic substance from the body with tonic and connecting pole are coaxially wholely set, and elastic press is fixed on metal expelling the toxic substance from the body with tonic.
Circle is as the cross section of optimal technical scheme of the present utility model, the elastic press and metal expelling the toxic substance from the body with tonic.
Used as optimal technical scheme of the present utility model, the shell body is coordinated using screw thread with cut-off socket to be fixed, and
Sealing ring is provided with shell body bottom and cut-off socket cooperation, leakage at cooperation is prevented.
The beneficial effect of long-life stop valve of the present utility model：
Long-life stop valve of the present utility model, cut-off pressing plate upper surface are coaxially arranged with connecting pole with groove, middle
Jacking sleeve bottom is enclosed within connecting pole, and intermediate lift sleeve bottom closes up to axle center in the groove of connecting pole, makes cut-off
Pressing plate and intermediate lift sleeve bottom are formed mutually to rotate and are hinged, elasticity pressure when such structure rotates can cut-off pressing plate
Block will not be rotated with, therefore avoid the abrasion of elastic press pressure-bearing, so as to substantially increase the service life of elastic press,
Avoid stop valve and fit badly and seep water phenomenon, while also improving the service life of stop valve.
