Lifting in side guide slot, and be pressed on by the lug of bottom on valve seat, wherein setting sealing strip and flashboard in side guide slot
End face be mutually adjacent to form sealing, to ensure the leakproofness of knife gate valve.
During for conveying mud, the pressure for generally requiring knife gate valve is relatively high, but its sealing effect has certain lack
It falls into：When pressure medium is high, often opening and closing can make sealing surface wear excessive, cause to leak, while impurity also can be to close in medium
Front cover is worn, and causes to leak.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of for conveying the high pressure of mud
Knife gate valve can be adapted for hyperbaric environment, keep effective leakproofness.
To achieve the above object, the utility model provides following technical solution：
A kind of high-voltage switch valve for being used to convey mud, including valve body, valve rod and flashboard, the valve body is installed with mutually
Mounting hole and runner are connected, valve deck is equipped in the top of valve body, the valve deck forms pressure cavities with valve body；It is set on mounting hole
There is valve component, the valve component includes two symmetrical valve seats, and the flashboard is placed between two valve seats, wherein valve
The end face and flashboard of seat are inconsistent, and the side wall of other end and mounting hole is inconsistent.
The utility model is further set：The valve component further includes pedestal, the pedestal include base body and
Two mounting portions in base body are symmetrically distributed in, the valve seat is placed on mounting portion.
The utility model is further set：The base body is equipped with the pilot hole worn for flashboard, base body it is outer
Side wall is equipped with annular flange, and the annular flange is placed between valve deck and valve body.
The utility model is further set：The madial wall of the pilot hole is equipped with several guide protrusions, is symmetrically distributed in
The both sides of flashboard.
The utility model is further set：The valve seat is manufactured using rubber.
The utility model advantageous effect：The technical solution of the utility model, the flashboard are placed between two valve seats, wherein
The end face of valve seat and flashboard are inconsistent, and the side wall of other end and mounting hole is inconsistent, form first of sealing, first close
Envelope effective can avoid the impurity in fluid media (medium) from entering the normal operation that pressure cavities influence knife gate valve, while also to fluid
Medium plays the role of pressure buffer, when fluid media (medium) enters pressure cavities, at this time pressure cavities form second sealing can be with
Higher pressure is born, the technical solution of the utility model avoids traditional knife gate valve from being sealed only with rubber seal
Mode, effectively improve the pressure value that can be born of knife gate valve.

Specific embodiment
1 to Fig. 4 high-voltage switch valve embodiment for being used to convey mud a kind of to the utility model is done further referring to the drawings
It is described in detail.
A kind of high-voltage switch valve for being used to convey mud, including valve body 1, valve rod 2 and flashboard 3, the valve body 1 is installed with
Be interconnected mounting hole 11 and runner 12, and valve deck 4 is equipped in the top of valve body 1, and the valve deck 4 forms pressure cavities with valve body 1；
Valve component 5 is equipped on mounting hole 11, the valve component 5 includes two symmetrical valve seats 51, and the flashboard 3 is placed in
Between two valve seats 51, the wherein end face of valve seat 51 and flashboard 3 is inconsistent, and other end and the side wall of mounting hole 11 offset
It touches, forms first of sealing, first of sealing, which effective can avoid the impurity in fluid media (medium) from entering pressure cavities, influences knife
The normal operation of gate valve, while also fluid medium plays the role of pressure buffer, when fluid media (medium) enters pressure cavities, at this time
Pressure cavities, which form second sealing, can bear higher pressure, and the technical solution of the utility model avoids traditional knife gate valve
Only with the mode that rubber seal is sealed, the pressure value that can be born of knife gate valve is effectively improved.
Wherein described valve component 5 further includes pedestal 52, and the pedestal 52 includes base body 521 and is symmetrically distributed in
