Sealing means from inwall are all to use plane to plane, or using the conical surface to the sealing structure of the conical surface, traditional flat seal
Still need to grind after finishing even across numerical control to ensure that the sealing pair of valve seat flap has good surface roughness, and
Very high sealing force is needed to ensure microcosmic seam that the seal pressure of sealing surface is filled up by sealing surface elastic deformation between sealing pair
Gap causes valve seal to realize.That is, such sealing surface structure, the sealing property that easily there is sealing surface is not up to standard,
Medium in valve body flows out from the gap of sealing surface, if being intended to so that sealing property is strong, requirement on machining accuracy is just higher,
Need to carry out high-precision cooperation, complex process so that the labor intensity of operating personnel to valve base sealing portion and flap sealing
It is excessive.

The both sides of isolation inwall respectively constitute snout cavity and outlet plenum, and the snout cavity and outlet plenum are conducted by opening, the valve
Soft seal bar detachably is provided with valve, the soft seal bar is obliquely installed, the soft seal article includes the first seal section and the
Two seal sections, first seal section is to be provided with and described wedge-type seal block pair on wedge-type seal block, the isolation inwall
The support inclined-plane that should be set, second seal section includes setting on the first lug boss and the first depressed part, the isolation inwall
There are the second depressed part being correspondingly arranged with the first lug boss and the second lug boss being correspondingly arranged with the first depressed part.
It is preferred that, it is provided with the clamping part that section is T-shaped, the flap and is provided with and the card on the soft seal bar
If the standing groove that portion is correspondingly arranged.
It is preferred that, the soft seal bar passes through seccotine bonding connection with flap.
The utility model has the following advantages that relative to prior art, a kind of stop valve of the present utility model, and it is by setting
Put inclined soft seal bar to ensure sealing, soft seal bar includes the first seal section and the second seal section, and the first seal section is
The support inclined-plane being correspondingly arranged with wedge-type seal block is provided with wedge-type seal block, isolation inwall, wedge-type seal block and support are oblique
Face, which coordinates, constitutes first of sealing surface, and the second seal section includes being provided with the first lug boss and the first depressed part, isolation inwall
The second depressed part being correspondingly arranged with the first lug boss and the second lug boss being correspondingly arranged with the first depressed part, isolate inwall
It is made up of hard material, the first lug boss and the second depressed part constitute second sealing surface, the first depressed part and the second lug boss
Three seals face is constituted, three seals face can effectively ensure that flap with isolating the sealing between inwall.
