Description
Technical field
The utility model relates to a kind of knife gate valve, and more particularly, it relates to a kind of dual-sealKnife gate valve.
Background technology
Knife gate valve claims again cutter door gate valve, cutter type Parallel Slide Valves, and its opening and closing element is flashboard, flashboardThe direction of motion and flow direction are perpendicular, cut by knife-edge flashboard that can cutting fiber materialDisconnected medium.
At present, the Chinese patent that application number is 03228285.0 discloses a kind of knife-shape gate valveUpper hermetically-sealed construction, it comprises valve body, flashboard, is placed with enough on two side positions on valve body topAirtight and watertight padding, is encapsulated in airtight and watertight padding on valve body by gland, and realization is valve body top and flashboardBetween sealing, in this, hermetically-sealed construction only seals by airtight and watertight padding, when airtight and watertight padding damagesTime, will cause the leakage of knife gate valve, sealing property is bad.
Utility model content
The deficiency existing for prior art, it is a kind of dual that the purpose of this utility model is to provideThe knife gate valve of sealing, the sealing property of raising knife gate valve.
For achieving the above object, the utility model provides following technical scheme:
A knife gate valve for dual-seal, comprises valve body and flashboard, it is characterized in that: described valve bodyComprise the left valve barrel and the right valve barrel that cooperatively interact, the mating surface of described left valve barrel and right valve barrel is all establishedBe equipped with U-shaped seal groove and for the packing groove of airtight and watertight padding is installed, described U-shaped seal grooveBetween both ends, be provided with coupled logical transverse sealing groove; Described packing groove is positioned at transverse sealingThe top of groove; Described U-shaped seal groove is provided with U-shaped sealing strip, and described transverse sealing groove is provided with horizontal strokeTo sealing strip; In the time of valve closing, flashboard moves down, flashboard and U-shaped sealing strip and transverse sealingBar fits tightly.
The utility model further arranges: described U-shaped sealing strip and transverse sealing bar are integrated to be establishedPut, described U-shaped sealing strip and transverse sealing bar form closed loop shape structure.
The utility model further arranges: described U-shaped sealing strip and transverse sealing bar are hollowRubber weather strip.
The utility model further arranges: U-shaped sealing strip contacts with flashboard with transverse sealing barEnd face is wavy surface.
The utility model beneficial effect: valve body adopts split-type structural, is divided into left valve barrel and right valveBody, is convenient to the machined of valve body, improves dimensional accuracy and the quality of fit of valve body, simultaneously first leftThe U-shaped seal groove of valve body and right valve barrel is provided with U-shaped sealing strip, and described transverse sealing groove is provided with horizontal strokeTo sealing strip, then be screwed left valve barrel and right valve barrel, make U-shaped sealing strip and horizontalSealing strip is fixed on valve body, can not be subjected to displacement along with flashboard lifting, when the sealing of packing grooveWhen filler damages, transverse sealing bar still can seal, and can not cause leaking, and improves cutterThe sealing property of gate valve makes user of service have enough time to go to change airtight and watertight padding simultaneously.

Detailed description of the invention
With reference to accompanying drawing 1 to Fig. 3, the knife gate valve of a kind of dual-seal of the utility model is done furtherDescribe in detail.
A knife gate valve for dual-seal, comprises valve body 1 and flashboard 2, and described valve body 1 comprisesThe left valve barrel 11 cooperatively interacting and right valve barrel 12, valve body 1 adopts split-type structural, is divided into a left sideValve body 11 and right valve barrel 12, be convenient to the machined of valve body 1, improves the dimensional accuracy of valve body 1And quality of fit.
The mating surface of described left valve barrel 11 and right valve barrel 12 be provided with U-shaped seal groove 3 andFor the packing groove 4 of airtight and watertight padding is installed, between the both ends of described U-shaped seal groove 3, be provided withCoupled logical transverse sealing groove 5, described packing groove 4 is positioned at the top of transverse sealing groove 5,Described U-shaped seal groove 3 is provided with U-shaped sealing strip 6, and described transverse sealing groove 5 is provided with laterally closeStrip of paper used for sealing 7, makes two of the formation on valve body 1 top seal positions, when the sealing of packing groove 4 is filled outWhen material damages, transverse sealing bar still can seal, and can not cause leaking, and improves disconnecting linkThe sealing property of valve makes user of service have enough time to go to change airtight and watertight padding simultaneously; SimultaneouslyU-shaped sealing strip 6 and transverse sealing bar 7 are fixed on valve body 1, can be along with flashboard 2Lifting is subjected to displacement, and described U-shaped sealing strip 6 and transverse sealing bar 7 are integrated setting, described inU-shaped sealing strip 6 and transverse sealing bar 7 form airtight circulus, improve the sealing of knife gate valveProperty, also prevent that U-shaped sealing strip 6 and transverse sealing bar 7 are subjected to displacement simultaneously; Work as valve closingTime, flashboard 2 moves down, and flashboard 2 fits tightly with U-shaped sealing strip 6 and transverse sealing bar 7.
Wherein said U-shaped sealing strip 6 and transverse sealing bar 7 are hollow rubber weather strip, UThe end face that shape sealing strip 6 contacts with flashboard 2 with transverse sealing bar 7 is wavy surface, can improveSealing property.
The above is only preferred embodiment of the present utility model, protection model of the present utility modelEnclose and be not only confined to above-described embodiment, all to belong to technical scheme under the utility model thinking equalBelong to protection domain of the present utility model. It should be pointed out that the ordinary skill for the artPersonnel, in the some improvements and modifications that do not depart under the utility model principle prerequisite, theseImprovements and modifications also should be considered as protection domain of the present utility model.
