Abstract
The utility model discloses a pipe seal assembly, including steel body, the body tip is equipped with seal part, seal part includes two clamp plates of mutually supporting and sets up at the annular pneumatic rubber capsules between the clamp plate, the clamp plate is the plectane, the coaxial setting of clamp plate, the inboard edge of clamp plate of coaxial setting is equipped with oriented slant, narrow outer wide annular pneumatic rubber capsules held the region in two oriented slant constituteed, annular pneumatic rubber capsules holds and is equipped with annular pneumatic rubber capsules in the region, annular pneumatic rubber capsules edge and oriented slant and the sealed cooperation of pipe inner wall elasticity, be equipped with the connecting rod between the clamp plate, it aerifys the pipe to be equipped with on the annular pneumatic rubber capsules, it passes the clamp plate and stretches out the outside to aerify the pipe. Can be with the inner wall and external separation of body through seal part to fine preservation is played to pipe inner wall to the contact of avoiding and corroding the thing.
Description
Technical field
The utility model relates to a kind of pipe black box.
Background technique
As everyone knows, existing engineering pipe, in particular for the round steel pipe of iron skill, 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 is badly in need of the good pipe black box of a kind of anticorrosion ability.
Model utility content
The purpose of this utility model is to overcome the defect existed in prior art, provides the pipe black box that a kind of anticorrosion ability is good.
For achieving the above object, the technical solution of the utility model there is provided a kind of pipe black box, comprise the body of steel, described body end is provided with sealed member, the ring-shaped rubber air bag that described sealed member comprises two pressing plates cooperatively interacted and is arranged between pressing plate, described pressing plate is plectane, described pressing plate is coaxially arranged, the pressing plate inside edge of described coaxial setting is provided with guiding surface, narrow outer wide ring-shaped rubber air bag housing region in described two guiding surfaces composition, is provided with ring-shaped rubber air bag in described ring-shaped rubber air bag housing region; Described ring-shaped rubber cell edges coordinates with guiding surface and inboard wall of tube body elastic packing; Be provided with connecting rod between described pressing plate, described ring-shaped rubber air bag is provided with inflating catheter, and described inflating catheter stretches out outside through pressing plate.The inwall of body can be intercepted with extraneous by sealed member, thus avoid the contact with erosion, good antisepsis is played to inboard wall of tube body.
As preferably, the inboard wall of tube body contacted is coordinated to be provided with the annular groove coordinated with ring-shaped rubber air bag with ring-shaped rubber air bag.It is bonding with the sealing between inboard wall of tube body that such design can strengthen annular rubber pneumatic bag.
As preferably, described annular air-pocket is bonding by sealer with the position of guiding surface and inboard wall of tube body Elastic Contact.Such design further enhancing sealing.
Advantage of the present utility model and beneficial effect are: the inwall of body can be intercepted with extraneous by sealed member, thus avoid the contact with erosion, play good antisepsis to inboard wall of tube body.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, body; 2, pressing plate; 3, annular groove; 4, connecting rod; 5, inflating catheter; 6, guiding surface; 7, ring-shaped rubber air bag housing region; 8, ring-shaped rubber air bag; 9, anticorrosive coat.
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 shown in Figure 1, a kind of pipe black box, comprise the body 1 of steel, described body 1 end is provided with sealed member, the ring-shaped rubber air bag 8 that described sealed member comprises two pressing plates cooperatively interacted 2 and is arranged between pressing plate 2, described pressing plate 2 is plectane, described pressing plate 2 is coaxially arranged, pressing plate 2 inside edge of described coaxial setting is provided with guiding surface 6, described two guiding surfaces 6 form interior narrow outer wide ring-shaped rubber air bag 8 housing region 7, are provided with ring-shaped rubber air bag 8 in described ring-shaped rubber air bag 8 housing region 7; Described ring-shaped rubber air bag 8 edge coordinates with guiding surface 6 and body 1 inwall elastic packing; Be provided with connecting rod 4 between described pressing plate 2, described ring-shaped rubber air bag 8 is provided with inflating catheter 5, and described inflating catheter 5 stretches out outside through pressing plate 2.Inflating catheter 5 is unidirectional inflating catheter 5, prevents gas leak.
Body 1 inwall contacted is coordinated to be provided with the annular groove 3 coordinated with ring-shaped rubber air bag 8 with ring-shaped rubber air bag 8.
Described annular air-pocket is bonding by sealer with the position of guiding surface 6 and body 1 inwall Elastic Contact.
When operating, will be placed in ring-shaped rubber air bag 8 housing region 7 after ring-shaped rubber air bag 8 outside coating sealer, then pressing plate 2 and ring-shaped rubber air bag 8 are put into body 1 end, when designing, pressing plate 2 size needs to be slightly less than body 1 inner wall size; Then inflated in ring-shaped rubber air bag 8 by inflating catheter 5, ring-shaped rubber air bag 8 expands, under the effect of guiding surface 6, mainly expand to radial outside, and closely cooperate with annular groove 3, also closely cooperate with guiding surface 6 simultaneously, contacted bonding formation by ring-shaped rubber air bag 8 with the pressure extrusion between guiding surface 6 and body 1 inwall like this and seal.Above-mentioned parts are all set in the end of body 1, then in body 1, define sealing area, prevent entering of extraneous erosion.As one optimization, body 1 outer wall also arranges anticorrosive coat 9, such body 1 inside and outside wall just can realize anti-corrosion function.
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.
