Technical field
The utility model relates to a kind of gate valve, in particular to a kind of antitheft anti-misoperation type Wedge Gate Valves.
Background technique
The opening and closing element of flashboard is flashboard, and the direction of motion and flow direction of flashboard are perpendicular.Flashboard presses the screw thread position of valve rod
It sets to divide, Outside screw stem rising through handwheel type gate valve and inside screw nonrising stem type gate valve can be divided into.Wherein, Outside screw stem rising through handwheel type gate valve be flashboard together with valve rod relative to the axial direction of valve body
Direction is for linear motion.Therefore, to judge that in the intracorporal open degree of valve, indicator of opening only need to be arranged in flashboard on valve rod,
Dial is set on valve body.In use, need to only observe indicator of opening in the position of dial, that is, it can determine whether flashboard in valve body
Open degree.
Currently, gate valve by its structure can be divided into flat gate valve and wedge action valve in the market, and wedge action valve is to utilize V-shaped brake
The mutual wedging of V-arrangement valve seat in plate and valve channel realizes sealing to cooperate.But when V-shaped brake plate is relative to valve body axial direction side
To moving upwardly so that V-shaped brake plate is in long-term open state, V-shaped brake plate and V-arrangement valve seat junction are long-term exposed to dielectric ring
Under border, the junction Yi Qi surface forms fouling or other sundries.At this point, when V-shaped brake plate is moved down to realize that gate valve is closed
When, since there are impurity at the connection sealing of the V-arrangement valve seat in V-shaped brake plate and valve channel, so that between the two cannot be mutual
Wedging, the gap may make medium to be leaked, and there are security risks.

As shown in Figure 1, Figure 4 and Figure 5, valve seat 5 is set on valve body 1, and 2 liang of side planes of flashboard constitute and match with valve seat 5
The v-seal face of conjunction.When flashboard 2 is closed, v-seal face and 5 wedging of valve seat cooperate to realize sealing.Flashboard 2 and valve seat 5
Between be respectively arranged with seal 8 and lower seal 9.Upper seal 8 is built-in with lower seal 9 can be solid with valve seat 5
Surely the fixing seal block 10 connected and the mobile sealing block 11 that can be fixedly connected with flashboard 2, mobile sealing block 11 and fixation are close
Sealing between block 10 is to seal firmly, the side of mobile sealing block 11 be fixedly connected with to remove be attached to it is miscellaneous on fixing seal block 10
The shearing sealing block 12 of matter, shearing sealing block 12 can be to fixing seal blocks 10 and mobile sealing block when flashboard 2 is closed
Impurity between 11 is purged.Shearing sealing block 12 is integrated with mobile sealing block 11 and connect.
Shearing sealing block 12 is preferably shaped to right angled triangle, the shearing sealing block 12 of right triangular shape, wherein one
A right-angle side is fixedly connected with mobile sealing block 11, another right-angle side can be abutted against with fixing seal block 10.And the right angle three
12 inclined-plane of shearing sealing block of angular shape, which can be used as shearing inclined-plane and prolong it come the impurity after guiding shearing sealing block 12 to remove, to be cut
Incisal bevel is slid.It is mobile when flashboard 2 is opened so that flashboard 2 is moved up relative to the axial direction of valve body 1
Sealing block 11 and flashboard 2 synchronize movement.When flashboard 2 be shut off such that flashboard 2 relative to the axial direction of valve body 1 carry out to
When lower mobile, it can will be moved between sealing block 11 and fixing seal block 10 positioned at the shearing sealing block 12 moved on sealing block 11
Sealing surface on accompanying sundries cut off, the sundries after excision, which prolongs it, to be sheared inclined-plane and is slid, to prevent from moving
There is sundries to retain between sealing block 11 and fixing seal block 10, influences sealing effect.
As shown in Figure 1, Figure 2 and Figure 3, packing seal component 7 includes upper packing element 13 and lower packing element 14, upper filler
Packing spring 15 is provided between part 13 and lower packing element 14.Upper packing element 13 is provided with filler far from the side of Packing spring 15
The side of gland 16, gland 16 is threadedly coupled with valve deck 4.Side of the lower packing element 14 far from Packing spring 15 and valve deck 4
It abuts against.Upper packing element 13 is superimposed with lower packing element 14 by several filling blocks 17,17 phase of any two filling block
The side being mutually bonded is provided with the semicircle air reservoir 18 through filling block 17.When any two filling block 17 is bonded to each other,
Its semicircle air reservoir 18 being located on two filling blocks 17 can enclose gas storage circular hole 19.Specifically, Packing spring
15 under the action of upper packing element 13, lower packing element 14 and gland 16, and Packing spring 15 is to be in compressive state, into
And the upper packing element 13 to two sides, lower packing element 14 can exert a force respectively, to ensure its sealing performance, so that flashboard 2
Sealing is realized with the mutual wedging of valve seat 5 to cooperate.
Since each filling block 17 is that inner circle and outer circle squeeze forced seal, pacify to several filling blocks 17
When dress, there are air between each filling block 17.By the setting of air reservoir 18, so that the filling block 17 that any two fit
Between can enclose gas storage circular hole 19.When installing to several filling blocks 17, air is extruded into gas storage circular hole 19.
Extruded air can squeeze 19 inner wall of gas storage circular hole, and then exert a force to corresponding filling block 17, with reinforcement filler block
Sealing performance between 17 inner headed face and valve rod 3 and the leakproofness between the periphery and valve deck 4 of reinforcement filler block 17
Energy.Simultaneously as Packing spring 15 is used between upper packing element 13 and lower packing element 14, so that packing seal component 7 uses
" spring+filler " structure.When valve cavity pressure is higher, then 7 sealing performance of packing seal component is better, and filler has low loss
Performance.
