Not inconsistent with bonnet and valve rod, the both ends of second spring are inconsistent with valve rod and flap respectively, pass through the first spring of setting
And second spring, and flap and valve rod are arranged to be flexibly connected so that it is not to rely on valve rod when valve rod is gradually screwed into
Directly part flap is acted on, but by coordinating the resilient support of the first spring and second spring, so as to reach extraction lock
Effect tight or that connection locking is reserved, and then good anti-locking effect is ensure that, gasket seal includes offseting with cut-off block
Tactile resistance surface, resistance surface are provided with some grooves, and groove is in arc-shaped, by being provided with some grooves, groove in resistance surface
In arc-shaped, pass through some grooves being provided with resistance surface so that knot of the groove formed with similar sucker shape on cut-off block
Structure, so as to improve the good effect that is completely embedded, and resistance surface is also easily because groove forms the effect of water seal.
The utility model is further arranged to：Set on the bonnet includes bottom land and both sides with buffering annular groove, buffering annular groove
Cell wall, the angle between the cell wall of both sides is between 28 degree of -35 degree.
By using above-mentioned technical proposal, set on bonnet with buffering annular groove, by the buffering annular groove being arranged on bonnet,
When flap is opened, fluid can be made to enter row buffering in buffering annular groove, and the section for buffering annular groove is in arc-shaped, then improves
The buffering effect of convection body, by the buffering of convection body, is reduced to the impact between valve rod and bonnet, and then ensure that close
Effect is sealed, improves the stability used, further includes bottom land and both sides cell wall in buffering annular groove, by by both sides cell wall
Between the angle buffering effect for receiving scope, improving convection body impact that adds convection body between 28 degree of -35 degree.
The utility model is further arranged to：The valve body is externally provided with reinforcement.
By using above-mentioned technical proposal, valve body is externally provided with reinforcement, by the reinforcement being arranged at outside valve body, then improves
The structural strength of valve body, it is ensured that good practical function.
Brief description of the drawings
