Valve is equipped with gasket seal, and the gasket seal is connected with flap by connection bolt, is arranged in the cut-off portion
There is convex shape annular groove, convex shape annular groove is made of upper slot and lower slot, and it is stifled that convex shape ring is provided on the convex shape annular groove
Block, convex shape ring sprue are made of protrusion and support portion, and the convex shape ring sprue is magnetite, and convex shape ring sprue is convex
Portion's height is greater than the upper groove height of convex shape annular groove, but the support portion height of convex shape ring sprue is less than the lower slot of convex shape annular groove
Height, and the flap is made of ferromagnetic material.
By using above-mentioned technical proposal, the convex shape annular groove in the cut-off portion of valve body, and be arranged on convex shape annular groove
The convex shape ring sprue of magnetite, and flap is made of ferromagnetic material, when flap and cut-off portion are inconsistent, the convex shape
Ring convex block can by with itself magnetism must firmly be adsorbed on flap, when flap is far from cut-off portion, convex shape ring convex block due to
It is separated by the similar of convex shape annular groove with flap, to reach more good sealing effect.
The utility model is further arranged to: it is ternary second that material is provided on the protrusion of the convex shape ring sprue
The gasket of third rubber.
By using above-mentioned technical proposal, gasket is set on the protrusion of convex shape ring sprue, gasket can improve convex
Sealing shape when font ring sprue and valve flap contacts, to further improve the sealing effect of cut-off valve body.
The utility model is further arranged to: the gasket seal is adapted with runner mouth, and in the sealing block
Bottom is provided with transition part.
By using above-mentioned technical proposal, gasket seal is adapted with runner mouth, when the valve is fully shut, gasket seal
Runner mouth can be blocked completely, to play the good effect shut off with sealing, and sealing block bottom is provided with transition part,
Transition part can play certain guiding role, moreover it is possible in valve closing process at ensuring that gasket seal is not worn.
The utility model is further arranged to: being provided with limit spring between the flap and valve body.
By using above-mentioned technical proposal, it is provided with limit spring between flap and valve body, flap can be risen most
Multiposition is defined, with ensure flap not with valve body contact and shine at abrasion, so as to improve the practicability of gate valve ontology.
