Abstract
The utility model relates to a gate valve, in particular to a gate valve flashboard and valve seat connecting structure. The technical scheme is that the gate valve flashboard and valve seat connecting structure comprises the valve seat and the flashboard in insertion connection with the valve seat. The valve seat is provided with a groove for the flashboard to be inserted, a side wall of the flashboard corresponding to the end face of the bottom of the groove of the valve seat is provided with a plurality of semicircular antifriction protrusions, and elastic sealing mechanisms are respectively arranged between the antifriction protrusions. According to the technical scheme, the gate valve flashboard and valve seat connecting structure is small in friction coefficient and good in sealing performance.
Description
Technical field
The utility model relates to a kind of gate valve, particularly the linkage structure of a kind of flashboard of gate valve and valve seat.
Background technique
Gate valve refers to the valve that closure member (flashboard) moves along the Vertical direction of path center line.Gate valve mainly is used as to cut off in pipeline.It mainly is provided with the connection chamber of medium inlet passage, medium flow pass and connecting media inlet passage and medium flow pass by valve body, valve body, the flashboard that is provided with valve seat in connection chamber and coordinates with valve base sealing, and valve body is provided with the actuator that drives flashboard.
Traditional valve seat comprises the groove be provided with the flashboard adaptation, and flashboard and valve seat, by hard hermetically enclosed connection chamber, impel the medium inlet passage of valve body and medium to flow out channel enclosed.Yet flashboard, in running, produces larger friction between meeting and valve seat, make the sealing surface of valve seat or flashboard impaired, after using for a long time, valve body there will be the situation of leakage.
Summary of the invention
The deficiency existed for prior art, the utility model provides that a kind of friction factor is little, the linkage structure of the flashboard of the gate valve of good airproof performance and valve seat.
For achieving the above object, the utility model provides following technological scheme: a kind of flashboard of gate valve and the linkage structure of valve seat, but include, valve seat reaches and the flashboard of valve seat socket connection, valve seat is provided with the groove plugged for flashboard, it is characterized in that: the sidewall that described flashboard is corresponding with valve seat bottom portion of groove end face is provided with the antifriction projection of some semicircle shapes, between each antifriction projection, is respectively equipped with elastic packing mechanism.
Wherein, offer standing groove on the sidewall of flashboard, described elastic packing mechanism includes and is located at installing frame in standing groove, the spring that compresses of being located in installing frame reaches with an end and compresses the spring conflict, the hard sealing block that the other end and installing frame are conflicted, the opening that installing frame is positioned at standing groove is provided with shrouding, shrouding is provided with the spacing hole that impels installing frame inside and outside conducting, hard sealing block includes working end and the end of conflicting, its working end sees through spacing hole and extends to outside standing groove, conflict end in installing frame and with compress spring and conflict and coordinate.
Adopt technique scheme, by the antifriction projection of semicircle shape is set on flashboard, flashboard is in movement process, antifriction projection on it can be conflicted with valve seat, prevent that flashboard is impaired, the setting of the elastic packing mechanism between each antifriction projection is in order to seal, hard sealing block in elastic packing mechanism is to implementing sealing between flashboard and valve seat, the conflict that compresses spring makes hard sealing block have the driving force of extending towards valve seat, also can after hard sealing block is frayed, can access micro-positioning regulators when having guaranteed sealability, make flashboard and valve seat remain sealing state.
The utility model further is set to: sealing layer has been sticked on the inwall of valve seat.
Adopt technique scheme, the further sealing guaranteed between valve seat and flashboard is set like this.
Below in conjunction with accompanying drawing, the utility model is further described.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment;
The A-A generalized section that Fig. 2 is Fig. 1;
The I section enlarged diagram that Fig. 3 is Fig. 2.
Embodiment
The flashboard of a kind of gate valve as shown in Fig. 1-Fig. 3 and the linkage structure of valve seat, but include, valve seat 1 reaches and the flashboard 2 of valve seat 1 socket connection, valve seat 1 is provided with the groove 11 plugged for flashboard 2, and the sidewall that flashboard 2 is corresponding with valve seat 1 groove 11 bottom end faces is provided with antifriction protruding 3 of some semicircle shapes.In such scheme, by the antifriction protruding 3 of semicircle shape is set on flashboard 2, flashboard 2 is in movement process, on it antifriction protruding 3 can be conflicted with valve seat 1, prevent that flashboard 2 is impaired, due to Multi-point contact type, the friction factor between flashboard 2 and valve seat 1 is diminished.
In the utility model embodiment, be respectively equipped with elastic packing mechanism 4 at each between antifriction protruding 3, offer standing groove 21 on the sidewall of flashboard 2, elastic packing mechanism 4 includes and is located at the interior installing frame 41 of standing groove 21, the spring 42 that compresses of being located in installing frame 41 reaches with an end and compresses spring 42 conflicts, the hard sealing block 43 that the other end and installing frame 41 are conflicted, the opening that installing frame 41 is positioned at standing groove 21 is provided with shrouding 44, shrouding 44 is provided with the spacing hole 441 that impels installing frame 41 inside and outside conducting, hard sealing block 43 includes working end 431 and the end 432 of conflicting, its working end 431 sees through spacing hole 441 and extends to outside standing groove 21, conflict end 432 in installing frame 41 in and with compress spring 42 conflicts and coordinate.Implement sealing between 43 pairs of flashboards 2 of hard sealing block in elastic packing mechanism 4 and valve seat 1, the conflict that compresses spring 42 makes hard sealing block 43 have the driving force of extending towards valve seat 1, also can after hard sealing block 43 is frayed, can access micro-positioning regulators when having guaranteed sealability, make flashboard 2 and valve seat 1 remain sealing state.In order further to guarantee the sealability between valve seat 1 and flashboard 2, sealing layer 5 has been sticked on the inwall of valve seat 2.Sealing layer 5 can be sealing gasket or hard sealing block, is all feasible.
