Abstract
The utility model discloses a knife gate's flashboard sealing rubber circle aims at providing a simple structure, the knife gate's flashboard sealing rubber circle of the installation of being convenient for, and its technical scheme main points are the U -shaped rubber circle bodies and horizontal sealing strip that set up including an organic whole, horizontal sealing strip setting is at the open end of U -shaped rubber circle body, horizontal sealing strip includes the horizontal sealing strip in preceding horizontal sealing strip and back, preceding horizontal sealing strip sets up with the horizontal sealing strip interval in back and forms the clearance that supplies the flashboard to reciprocate, the U -shaped rubber circle body medial surface outside protruding formation protruding sealing inconsistent with the flashboard, the lower terminal surface of preceding horizontal sealing strip and the horizontal sealing strip in back all inwards caves in and forms the V -arrangement recess.
Description
Technical field
This utility model relates to the parts of knife gate valve, more specifically, it relates to the ram seal rubber ring of a kind of knife gate valve.
Background technology
Knife gate valve is also known as cutter door gate valve, blade type Parallel Slide Valves, and its opening and closing element is flashboard, and the direction of motion of flashboard and flow direction are perpendicular, by the knife-edge flashboard of cutting fiber material cutting off medium.Valve body not actually exists chamber, and flashboard lifts in side guide groove, and is pressed on valve seat by the lug of bottom, wherein arranges the end face of sealing strip and flashboard at side guide groove and is adjacent to formation mutually and seals, ensures the sealing of knife gate valve.
The sealing strip of the sealing of the existing surrounding to flashboard is all respective independence, it is necessary to independently installed, is not easy to assembling, simultaneously top, bottom, left side, right side sealing strip installation can there is gap, reduce the sealing of flashboard.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of simple in construction, the ram seal rubber ring of knife gate valve that is easily installed.
For achieving the above object, this utility model provides following technical scheme:
A kind of ram seal rubber ring of knife gate valve, including the U-shaped rubber circle body being wholely set and transverse sealing bar, described transverse sealing bar is arranged on the opening of U-shaped rubber circle body, described transverse sealing bar includes front transverse sealing bar and rear transverse sealing bar, described front transverse sealing bar and rear transverse sealing bar interval and arranges the gap that formation moves up and down for flashboard；The inconsistent inner side end outwardly convex of described U-shaped rubber circle body and flashboard forms raised seals portion, and the lower surface of described front transverse sealing bar and rear transverse sealing bar all caves inward formation v-depression.
This utility model is arranged further: the opposite face of described front transverse sealing bar and rear transverse sealing bar all caves inward formation sealed groove.
This utility model is arranged further: v-depression is made up of outer lips and epipharyngeal sclerites, and described epipharyngeal sclerites and flashboard fit.
This utility model is arranged further: the thickness of described epipharyngeal sclerites is less than outer lips, and described epipharyngeal sclerites stretches out length more than outer lips.
nullThis utility model beneficial effect: during use，Only this ram seal rubber ring need to be arranged in valve body，Flashboard is when valve body moves up and down，Front transverse sealing bar and rear transverse sealing bar it is placed in due to flashboard，And front transverse sealing bar is adjacent to the both ends of the surface of flashboard respectively mutually with rear transverse sealing bar，The lower surface of described front transverse sealing bar and rear transverse sealing bar all caves inward formation v-depression，When flashboard barrier liquid medium passes through，This liquid medium can extrude the medial wall of v-depression and tightly be fitted in the end face of flashboard，Thus ensureing the sealing property of front transverse sealing bar and rear transverse sealing bar and flashboard，When flashboard moves down simultaneously，The outward flange of flashboard can expression lobes sealing，The outward flange making described U-shaped rubber circle body and flashboard fits tightly，Thus ensureing the sealing property of knife gate valve，The surrounding sealing of flashboard has only to install a ram seal rubber ring and just can realize，Simple in construction、It is easily installed.

Detailed description of the invention
With reference to accompanying drawing 1 to Fig. 2, the ram seal rubber ring of a kind of knife gate valve of this utility model is described in further details.
A kind of ram seal rubber ring of knife gate valve, including the U-shaped rubber circle body 1 being wholely set and transverse sealing bar 2, described transverse sealing bar 2 is arranged on the opening of U-shaped rubber circle body 1, described transverse sealing bar 2 includes front transverse sealing bar 21 and rear transverse sealing bar 22, described front transverse sealing bar 21 and rear transverse sealing bar 22 interval and arranges the gap that formation moves up and down for flashboard；The inner side end outwardly convex formation raised seals portion 11 that described U-shaped rubber circle body 1 is inconsistent with flashboard, the lower surface of described front transverse sealing bar 21 and rear transverse sealing bar 22 all caves inward and forms v-depression 3, v-depression 3 is made up of outer lips 31 and epipharyngeal sclerites 32, described epipharyngeal sclerites 32 fits with flashboard, more it is fitted tightly on the end face of flashboard for the ease of epipharyngeal sclerites 32, the thickness of described epipharyngeal sclerites 32 is less than outer lips 31, and described epipharyngeal sclerites 32 stretches out length more than outer lips 31, and the opposite face of described front transverse sealing bar 21 and rear transverse sealing bar 22 all caves inward and forms sealed groove 4.
nullDuring use，Only this ram seal rubber ring need to be arranged in valve body，Flashboard is when valve body moves up and down，Front transverse sealing bar 21 and rear transverse sealing bar 22 it is placed in due to flashboard，And front transverse sealing bar 21 is adjacent to the both ends of the surface of flashboard respectively mutually with rear transverse sealing bar 22，The lower surface of described front transverse sealing bar 21 and rear transverse sealing bar 22 all caves inward and forms v-depression 3，When flashboard barrier liquid medium passes through，This liquid medium can extrude the epipharyngeal sclerites 32 of v-depression 3 and tightly be fitted in the end face of flashboard，Thus ensureing the sealing property of front transverse sealing bar 21 and rear transverse sealing bar 22 and flashboard，When flashboard moves down simultaneously，The outward flange of flashboard can expression lobes sealing 11，The outward flange making described U-shaped rubber circle body 1 and flashboard fits tightly，Thus ensureing the sealing property of knife gate valve，The surrounding sealing of flashboard has only to install a ram seal rubber ring and just can realize，Simple in construction、It is easily installed.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
