Abstract

The utility model discloses a square pipe, including steel body, be equipped with isolation parts on the pipe inner wall of body tip, isolation parts includes the seal membrane and compresses tightly the seal membrane in the rubber card strip of four arriss of body, the seal membrane include the basement membrane and with basement membrane sealing connection's square column type section of thick bamboo membrane, square column type section of thick bamboo membrane forms a tip with the basement membrane and is equipped with open -ended bag form membrane, four arriss of pipe inner wall are equipped with the draw -in groove, rubber card strip compresses tightly the joint in the draw -in groove with four arriss of square column type section of thick bamboo membrane, the setting is hugged closely with the body internal surface to square column type section of thick bamboo membrane surface, body between isolation parts and the isolation parts forms keeps apart the region. Form in the body through isolation parts and keep apart the regional contact that can keep apart the inner wall and corrode the thing, play fine preservation to pipe inner wall.

Description

A kind of square tubular

Technical field

The utility model relates to a kind of square tubular.

Background technique

As everyone knows, existing engineering pipe, in particular for the square 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 effective square tubular of a kind of inner wall anti-corrosive.

Model utility content

The purpose of this utility model is to overcome the defect existed in prior art, provides the square tubular that a kind of inner wall anti-corrosive is effective.

For achieving the above object, the technical solution of the utility model there is provided a kind of square tubular, comprise the body of steel, the inboard wall of tube body of described body end is provided with isolating part, and described isolating part comprises sealing film and sealing film is pressed in the rubber card article of body four rib; The square column type tube film that described sealing film comprises counterdie and is tightly connected with counterdie, described square column type tube film and counterdie form the bag-shaped film that an end is provided with opening, described inboard wall of tube body four rib is provided with draw-in groove, and four ribs of square column type tube film compress and are connected in draw-in groove by described rubber card article; Described square column type tube film outer surface and inner surface of tube body are close to setting; Body between described isolating part and isolating part forms area of isolation.In body, form by isolating part the contact that area of isolation can isolate inwall and erosion, good antisepsis is played to inboard wall of tube body.

As preferably, four inwalls of described body are provided with miniature arc convex, and described square column type tube film four outer walls and corresponding inboard wall of tube body closely cooperate.Such design makes the inwall of body have certain projection, four ribs of square column type tube film are depression comparatively speaking, in the process that four ribs compress, the close contact of square column type tube film and arc convex can be impelled further, for I better realizes above-mentioned functions, can select that there is the material of flexible latex film as square column type tube film.

As preferably, described square column type tube film is with to be provided with sealer between inboard wall of tube body bonding.Such design can improve isolation effect further.

Advantage of the present utility model is with beneficial effect: in body, form area of isolation by isolating part and can isolate contacting of inwall and erosion, play good antisepsis to inboard wall of tube body.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is A-A sectional view in Fig. 1.

In figure: 1, body; 2, rubber card article; 3, counterdie; 4, square column type tube film; 5, draw-in groove; 6, area of isolation; 7, arc convex.

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 Figure 1-Figure 2, a kind of square tubular, comprises the body 1 of steel, and body 1 inwall of described body 1 end is provided with isolating part, and described isolating part comprises sealing film and sealing film is pressed in the rubber card article 2 of body 1 four rib; The square column type tube film 4 that described sealing film comprises counterdie 3 and is tightly connected with counterdie 3, described square column type tube film 4 forms with counterdie 3 the bag-shaped film that an end is provided with opening, described body 1 inwall four rib is provided with draw-in groove 5, and four ribs of square column type tube film 4 compress and are connected in draw-in groove 5 by described rubber card article 2; Described square column type tube film 4 outer surface and body 1 internal surface are close to setting; Body 1 between described isolating part and isolating part forms area of isolation 6.Described draw-in groove 5 and rubber card article 2 are arranged all vertically.

Four inwalls of described body 1 are provided with miniature arc convex 7, and described square column type tube film 4 four outer walls and corresponding body 1 inwall closely cooperate.

Described square column type tube film 4 is with to be provided with sealer between body 1 inwall bonding.

When operating, coating sealer on body 1 inwall and in draw-in groove 5, isolating part is placed in place, by external force, rubber card article 2 compression is connected in draw-in groove 5, four ribs of square column type tube film 4 are also connected in draw-in groove 5 simultaneously, 4 four the membranous wall tensions of square column type tube film closely cooperate with arc convex 7, square column type tube film 4 is bonding with body 1 inwall, the isolation inside and outside body 1 is achieved by isolating part, body 1 end all arranges above-mentioned isolating part, just can realize forming area of isolation 6 to the isolation of body 1 inside; Body 1 outer wall arranges anticorrosive coat.

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.
