It is in arc-shaped by supporting side walls, when being pushed flap by valve rod, supporting side walls can be then flap while stress
Two-way active force is provided with cut-off block, so as to further increase sealing effectiveness.
The utility model is further arranged to：The gasket seal includes the resistance surface inconsistent with cut-off block, resistance surface
Some grooves are provided with, groove is in arc-shaped.
By using above-mentioned technical proposal, gasket seal includes the resistance surface inconsistent with cut-off block, and resistance surface is provided with
Some grooves, groove are in arc-shaped, and by being provided with some grooves in resistance surface, groove is in arc-shaped, by resistance surface
Some grooves being provided with so that structure of the groove formed with similar sucker shape on cut-off block, so as to improve good connection
Close effect, 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 with annular groove is buffered, the section for buffering annular groove is in arc-shaped.
By using above-mentioned technical proposal, set on bonnet with annular groove is buffered, the section for buffering annular groove is in arc-shaped, by setting
The buffering annular groove put, when flap is opened, fluid can be made to enter row buffering in buffering annular groove, and buffer the section of annular groove
In arc-shaped, then the buffering effect of convection body is improved, by the buffering of convection body, is reduced to rushing between valve rod and bonnet
Hit, and then ensure that sealing effectiveness, improve the stability used.
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
