Abstract
The utility model discloses a sealing plug with limiting plate, including an annular elastic emulsion cover and the circular fixed plate of bonding on an elastic emulsion cover terminal surface, it has a circular limiting plate to bond on another terminal surface of elastic emulsion cover, be connected through spacing rope between circular fixed plate and the circular limiting plate, the elastic emulsion cover is hollow seal cover, be equipped with the injection port on the seal cover, be equipped with the check valve on the injection port, it is outwardly directed that the check valve passes circular fixed plate. Through with this application the sealing plug setting at the tip of body for the inside formation of body keeps apart the region, can prevent pipe inner wall's corruption effectively.
Description
Technical field
The utility model relates to a kind of sealing plug being provided with limiting board.
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 is badly in need of a kind of sealing plug being provided with limiting board preventing inboard wall of tube body from corroding.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of sealing plug being provided with limiting board preventing inboard wall of tube body from corroding.
For achieving the above object, the technical solution of the utility model there is provided a kind of sealing plug being provided with limiting board, comprise an annular elastic emulsion cover and be bonded in elastic emulsion and overlap circular fixed plate on an end face, other end is bonded with one piece of circular limiting board with elastic emulsion cover, and described circular fixed plate is connected by limit rope with between circular limiting board; Described elastic emulsion cover is the stuffing box gland of hollow, and described stuffing box gland is provided with injection port, and described injection port is provided with one-way valve, and described one-way valve is protruding through circular fixed plate.By the sealing plug described in the application being arranged on the end of body, making tubular body form area of isolation, effectively can prevent the corrosion of inboard wall of tube body.
As preferably, described elastic emulsion cover outer rim is coated with sealer.Such design be convenient to elastic emulsion cover outer rim with seal between tubular body bonding.
As preferably, described circular fixed plate and circular limiting board size are all less than elastic emulsion cover.The installation of assembly is convenient in such design.
Advantage of the present utility model and beneficial effect are: by the sealing plug described in the application being arranged on the end of body, make tubular body form area of isolation, effectively can prevent the corrosion of inboard wall of tube body.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, elastic emulsion cover; 2, circular fixed plate; 3, circular limiting board; 4, limit rope; 5, one-way valve; 6, sealer.
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 sealing plug being provided with limiting board, the circular fixed plate 2 comprising an annular elastic emulsion cover 1 and be bonded on elastic emulsion cover 1 one end faces, elastic emulsion overlaps on 1 other end and is bonded with one piece of circular limiting board 3, and described circular fixed plate 2 is connected by limit rope 4 with between circular limiting board 3; Described elastic emulsion cover 1 is the stuffing box gland of hollow, and described stuffing box gland is provided with injection port, and described injection port is provided with one-way valve 5, and described one-way valve 5 is protruding through circular fixed plate 2.
Described elastic emulsion overlaps 1 outer rim and is coated with sealer 6.
Described circular fixed plate 2 and circular limiting board 3 size are all less than elastic emulsion cover 1.
In use, by clean for body (pipe) inner wall cleaning, the sealing plug of the application is placed on the end of body, first the gas in emptying elastic emulsion cover 1, then A glue is injected in elastic emulsion cover 1 by one-way valve 5, along with the amount injected strengthens, elastic emulsion overlaps 1 volumetric expansion, owing to being connected by limit rope 4 between circular fixed plate 2 with circular limiting board 3, when elastic emulsion overlaps 1 volumetric expansion to certain degree, limit rope 4 can be tightened, elastic emulsion cover 1 is limited in the expansion space of axis, elastic emulsion is forced to overlap 1 to radial expansion, outer rim outwards expands, fully contact with inboard wall of tube body and structure coincide, now inject B glue, A glue B glue is mixed and solidifying and setting, elastic emulsion overlaps 1 outer rim and inboard wall of tube body is sealed by sealer 6.In order to prevent the wet gas in body in residual air, circular limiting board 3 interior edge face is provided with drying part, so just can keep the dry bath in body for a long time.The AB glue used in the application is the another name of two liquid mixed hardening glue, and A liquid is this glue, and B liquid is hardening agent, two liquid phases are mixed could harden, and is firmly must not answer maturation by temperature, so be the one of cold setting glue, make model to use sometimes, be generally used for industry.
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.
