The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments：
Please refer to Fig.1, Fig. 2, the utility model provides a kind of anti-wear gate valve, including valve body 1, above valve body 1
Bonnet 2 and the chamber 3 in valve body 1, chamber 3 is interior to be equipped with matched flashboard 4, and 3 top of chamber is equipped with and flashboard 4
The square tapered hole 5 to match, 3 lower part of chamber are equipped with the square taper slot 6 to match with flashboard 4, and flashboard 4 is connected with valve rod 7, valve rod
7 one end sequentially pass through valve body 1, bonnet 2 and are connected with handwheel 8, and sealing shroud 9 is arranged with outside the flashboard 4, and sealing shroud 9 is that fourth is fine
Rubber material；4 both sides of the flashboard are equipped with mutually symmetrical step 10；9 upper end edge of the sealing shroud extends inwardly and platform
The limit flange 11 that rank 10 matches, limit flange 11 fit on step 10；9 lower end edge of the sealing shroud extends inwardly
Anti-abrasion pad 12, anti-abrasion pad 12 are located at 4 bottom of flashboard, and anti-abrasion pad 12 fits with square 6 bottom of taper slot；It is set on the sealing shroud 9
It is in that longitudinal equally distributed annular braces slot 13 to have several；The annular braces in slot 13 and braces band equipped with matched
14, it is elastic material to brace band 14；12 center of the anti-abrasion pad is equipped with an opening 15.
The step 10 is at least two-stage step.
Gasket 16 is equipped between the valve body 1 and bonnet 2.
6 bottom of side's taper slot is equipped with a positive magnetic sheet 17；4 bottom of the flashboard is equipped with attracting with positive magnetic sheet 17
Cathode magnetic sheet 18.
The application method of the utility model is as follows：
When need to open gate valve, flashboard 4 can be made to be moved up towards 1 top of valve body, in flashboard by rotating handwheel 8 with ovable valve stem 7
During 4 move up, 4 rear surface of flashboard can mutually rub with the inner wall of square taper slot 6, and 4 outer surface of flashboard then can constantly with side
5 inner wall of tapered hole constantly rubs, and the presence of sealing shroud 9 can then be used as anti-grinding media, substitutes 4 outer surface of flashboard and square tapered hole
5 inner wall, the inner wall of side's taper slot 6 mutually rub, and can be reduced to the full extent and side using the sealing shroud 9 of nitrile rubber material
The friction level of the inner wall of tapered hole 5, the inner wall of side's taper slot 6, and the sealing shroud 9 of nitrile rubber has extremely strong wearability,
The case where presence of sealing shroud 9 can avoid flashboard 4 from being worn with square tapered hole 5, square 6 friction of taper slot, and sealing shroud 9
There is body certain elasticity, sealing shroud 9 can be changed into the rigid seal between flashboard and square tapered hole 5, square taper slot 6 soft
Property sealing, the seal degree higher of this sealing means is less susceptible to wear, and ensures the long-term effect of sealing, makes making for gate valve
It is protected with performance.
4 both sides of flashboard are equipped with mutually symmetrical step 10, and 9 upper end edge of sealing shroud is extended inwardly to match with step 10
Limit flange 11, limit flange 11 fit on step 10, when limit flange 11 fit in step 10 when, just be equal to be sticked in
On step 10, in 4 folding process of flashboard, one corresponding resistance can be formed, this strand of resistance then can pull power with flashboard 4
Balance is formed, sealing shroud 9 is made to fix in situ, during flashboard 4 moves up, anti-abrasion pad 12 can equally form corresponding resistance,
This strand of resistance equally can form balance with the power of pullling of flashboard 4, so that sealing shroud 9 is fixed in situ, it follows that limit flange 11
Presence with anti-abrasion pad 12 can limit the position of sealing shroud 9, ensure that 9 position of sealing shroud is not in change, when ensureing sealing
Stability, and the presence of anti-abrasion pad 12 can avoid 4 bottom of flashboard from the case where fretting wear occur with square 6 bottom of taper slot.
Sealing shroud 9 be equipped with it is several brace slot 13 in longitudinal equally distributed annular, annular brace be equipped in slot 13 and its
What is matched braces band 14, and it is elastic material to brace band 14, braces the presence of band 14 and can improve the firm of sealing shroud 9 again
Property, the power born when sealing shroud 9 deforms can be more shared, is avoided the occurrence of since 9 TERM DEFORMATION of sealing shroud leads to elastic fatigue
Situation, effectively extends the service life of sealing shroud 9, and braces band 14 and can more be used as sealing ring, a plurality of to brace band
The sealing effect between sealing shroud 9 and square tapered hole 5, square taper slot 6 can be further increased.
12 center of anti-abrasion pad is equipped with opening 15, and 15 presence of being open is stirred outward convenient for anti-abrasion pad 12, and limit is turned over
The presence on side 11 equally convenient for stirring outward, facilitates staff that sealing shroud 9 is disassembled or installed from flashboard 4
It goes, if aging or damage occurs in sealing shroud 9, staff then can quickly replace sealing shroud 9.
Step 10 is that at least two-stage step can further increase what limit flange was formed with the increase of step series
Resistance ensures the stability of 9 position of sealing shroud to the full extent to improve the limited degree of limit flange 11.
Gasket 16 is equipped between valve body 1 and bonnet 2, the presence of gasket 16 can increase the sealing between valve body 1 and bonnet 2
Property, it can also play the role of abrasionproof.
Square 6 bottom of taper slot is equipped with positive magnetic sheet 17, and 4 bottom of flashboard is equipped with the cathode magnetic sheet attracting with positive magnetic sheet 17
18, when gate valve is closed, the suction between positive magnetic sheet 17 and cathode magnetic sheet 18 can be to 9 section below of sealing shroud utmostly
It is squeezed, 9 part of sealing shroud after crimp can improve the sealing between flashboard 4 and square taper slot 6 to the full extent
Property, be not in water leakage situation, and between 9 part of sealing shroud being mixed between positive magnetic sheet 17 and cathode magnetic sheet 18 can play
Every effect, make not to be bonded attracting, flashboard 4 and square taper slot when being opened conducive to gate valve between positive magnetic sheet 17 and cathode magnetic sheet 18
Separation between 6.
