Abstract
The utility model discloses a closing plate with branching, including the centre plate, the centre plate is and flies butterfly shape, it has rubber to cover respectively to bond on two terminal surfaces of centre plate, the outside perk in rubber edge forms the sealing strip, the sealing strip forms the chevron shape branching, be equipped with the barrier film in the chevron shape branching, barrier film both sides edge sets up with two furcate inner walls of chevron shape are sealed respectively, the barrier film forms air fill area with the chevron shape branching, the outside extension of centre plate outer fringe is equipped with elasticity and draws the membrane, elasticity draws membrane one end and centre plate outer fringe fixed, and the other end is fixed with the barrier film, elasticity draws the epimembranal through -hole that is equipped with, be equipped with the gas pocket with external intercommunication with air fill area on the sealing strip, the gas pocket outside is equipped with the trachea. Through the closing plate with branching who uses this application, can seal up the inner wall of the tip of body to keep apart and handle, form in the body and keep apart regionally, avoid corroding thing and pipe inner wall contact.
Description
Technical field
The utility model relates to one and establishes forked sealing plate.
Background technique
As everyone knows, existing engineering pipe, pipe fitting in particular for iron skill is steel pipe, in the maintenance process in later stage, need that regular to carry out japanning to body antirust, body is hollow tubular, after first japanning, in maintenance process, inwall japanning is carried out very not easily to already installed body, but only to coated outside, inwall is easy to get rusty, from internal damage under comparatively moist or corrosion-prone environment.Prior art be badly in need of a kind of by inboard wall of tube body seal establish forked sealing plate.
Model utility content
The purpose of this utility model is to overcome the defect existed in prior art, provide a kind of by inboard wall of tube body seal establish forked sealing plate.
For achieving the above object, the technical solution of the utility model there is provided one and establishes forked sealing plate, comprise center plate, described center plate is butterfly-shaped in flying, two end faces of described center plate cover respectively and is bonded with rubber, described rubber edge outwards tilts formation sealing strip, described sealing strip forms man type bifurcated, isolating film is provided with in described man type bifurcated, described isolating film both sides of the edge are arranged with two inner wall sealings of man type bifurcated respectively, and described isolating film and man type bifurcated form air-filled region; Center plate outer rim stretches out and is provided with elastic force membrane, and described elastic force membrane one end and center plate outer rim are fixed, and the other end and isolating film are fixed; Described elastic force membrane is provided with through hole; Described sealing strip is provided with the pore be communicated with the external world air-filled region, is provided with tracheae outside described pore.By use the application establish forked sealing plate, the inwall of the end of body can be carried out seal isolation process, in body, form area of isolation, avoid erosion to contact with inboard wall of tube body.
As preferably, fix in the middle part of described elastic force membrane and isolating film.The strength that such design can make elastic force membrane pull the oriented center of isolating film, is conducive to sealing strip and draws close to center.
As preferably, described sealing strip thickness centrally panel edges is outwards thinning gradually.Such design raising sealing strip coordinates tightness with inboard wall of tube body.
Advantage of the present utility model and beneficial effect are: by use the application establish forked sealing plate, the inwall of the end of body can be carried out seal isolation process, in body, form area of isolation, avoid erosion to contact with inboard wall of tube body.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is A place structure enlarged diagram in Fig. 1.
In figure: 1, center plate; 2, rubber; 3, sealing strip; 4, man type bifurcated; 5, pore; 6, air-filled region; 7, isolating film; 8, tracheae; 9, through hole; 10, elastic force membrane.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2, one establishes forked sealing plate, comprise center plate 1, described center plate 1 is butterfly-shaped in flying, and two end faces of described center plate 1 cover respectively and is bonded with rubber 2, described rubber 2 edge outwards tilts and forms sealing strip 3, described sealing strip 3 forms man type bifurcated 4, be provided with isolating film 7 in described man type bifurcated 4, described isolating film 7 both sides of the edge are arranged with two inner wall sealings of man type bifurcated 4 respectively, and described isolating film 7 forms air-filled region 6 with man type bifurcated 4; Center plate 1 outer rim stretches out and is provided with elastic force membrane 10, and described elastic force membrane 10 one end and center plate 1 outer rim are fixed, and the other end and isolating film 7 are fixed; Described elastic force membrane 10 is provided with through hole 9; Described sealing strip 3 is provided with the pore 5 be communicated with the external world air-filled region 6, is provided with tracheae 8 outside described pore 5.
Fix in the middle part of described elastic force membrane 10 and isolating film 7.
Described sealing strip 3 thickness centrally plate 1 edge is outwards thinning gradually.
In use, by clean for the process of steel inboard wall of tube body, forked sealing plate of establishing described in the application is put into from the end of body, need to apply sealer between putting into inside sealing strip 3 He on isolating film 7, now tracheae 8 is connected with air-extractor, bled in air-filled region 6, elastic force membrane 10 is provided with through hole 9, under gas in air-filled region 6 is in negative pressure, isolating film 7 shrinks, isolating film 7 both sides of the edge seal bonding with sealing strip 3, and sealing strip 3 is pullled from two side direction centers by isolating film 7 in the process of shrinking; Elastic force membrane 10 is in extended state when air-filled region 6 is in inflated condition simultaneously, after bleeding in air-filled region 6, elastic force membrane 10 is taken advantage of a situation contraction, and pulls in the middle part of isolating film 7 and draw close to center plate 1, and isolating film 7 both sides are then pullled sealing strip 3 and drawn close to center; Under above two kinds of convergence effects, the sealing strip 3 that physical dimension is greater than body inside dimension can closely cooperate with inboard wall of tube body, and is bonded and sealed by sealer, and in like manner carry out seal isolation process to other ends of body, inboard wall of tube body just forms isolating seal region.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
