Abstract
The utility model discloses a tubular product with spiral adhesive tape and seal cover, including steel body, be close to be equipped with the seal cover on the pipe inner wall of body tip, body between the seal cover and seal cover enclose to close and form a sealing region, the body tip forms free region with the seal cover, at least one is the cecum two ports of seal cover, be equipped with the sealing washer on the seal cover outer wall, the sealing washer compresses tightly between seal cover and body, be equipped with the spiral adhesive tape around the body outer wall, body outer wall and free region coating have the epoxy layer, and regional formation the that is equipped with the spiral adhesive tape is strengthened bonding. Forming the contact that sealing region can keep apart the inner wall and corrode the thing through the seal cover in the body, thoroughly avoiding corroding, epoxy protective layer can protect other naked tube part through the coating.
Description
Technical field
The utility model relates to a kind of tubing being provided with spiral sealing tape and stuffing box gland.
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 the good tubing being provided with spiral sealing tape and stuffing box gland of a kind of anticorrosion ability.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides the tubing being provided with spiral sealing tape and stuffing box gland that a kind of anticorrosion ability is good.
For achieving the above object, the technical solution of the utility model is to provide a kind of tubing being provided with spiral sealing tape and stuffing box gland, comprise the body of steel, the inboard wall of tube body near described body end is provided with stuffing box gland, and the body between described stuffing box gland and stuffing box gland enclose formation sealing area; Body end and stuffing box gland form open area; Two ports of described stuffing box gland at least one be cecum, described stuffing box gland outer wall is provided with seal ring, and described seal ring is pressed between stuffing box gland and body; Spiral sealing tape is provided with around tube wall; Described tube wall and open area are coated with epoxy resin layer, and the region formation being provided with spiral sealing tape is strengthened bonding.In body, the contact that sealing area can isolate inwall and erosion is formed by stuffing box gland; thoroughly avoid corrosion; can the body portion exposed to other be protected by coating epoxy resin protective layer; remove the drawback of regular japanning from, sealing tape is for strengthening the firmness of the attachment of epoxy coating.
As preferably, described stuffing box gland outer wall is provided with the seal ring draw-in groove holding seal ring, and described cecum is arranged on the outer end of stuffing box gland.When such design prevents stuffing box gland grafting, seal ring slides axially.
As preferably, described epoxy resin layer is dip-coating layer, and described epoxy resin layer thickness is 3-6mm.Such design had both been conducive to protective tube body, may be controlled to this simultaneously.
Advantage of the present utility model is with beneficial effect: in body, form sealing area by stuffing box gland and can isolate contacting of inwall and erosion; thoroughly avoid corrosion; can the body portion exposed to other be protected by coating epoxy resin protective layer; remove the drawback of regular japanning from, sealing tape is for strengthening the firmness of the attachment of epoxy coating.

Fig. 2 is spiral sealing tape distributed architecture schematic diagram.
In figure: 1, body; 2, stuffing box gland; 3, sealing area; 4, open area; 5, epoxy resin layer; 6, cecum; 7, seal ring; 8, seal ring draw-in groove; 9, spiral sealing tape.
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 tubing being provided with spiral sealing tape and stuffing box gland, comprises the body 1 of steel, and body 1 inwall near described body 1 end is provided with stuffing box gland 2, and the body 1 between described stuffing box gland 2 and stuffing box gland 2 enclose formation sealing area 3; Body 1 end and stuffing box gland 2 form open area 4; Two ports of described stuffing box gland 2 at least one be cecum 6, described stuffing box gland 2 outer wall is provided with seal ring 7, and described seal ring 7 is pressed between stuffing box gland 2 and body 1; Spiral sealing tape 9 is provided with around body 1 outer wall; Described body 1 outer wall and open area 4 are coated with epoxy resin layer 5, and the region formation being provided with spiral sealing tape 9 is strengthened bonding.
Described stuffing box gland 2 outer wall is provided with the seal ring draw-in groove 8 holding seal ring 7, and described cecum 6 is arranged on the outer end of stuffing box gland 2.
Described epoxy resin layer 5 is dip-coating layer, and described epoxy resin layer 5 thickness is 3-6mm.
When making, first seal ring 7 is connected in the seal ring draw-in groove 8 of stuffing box gland 2, sealer is smeared outside seal ring 7, stuffing box gland 2 is inserted in body 1, by rational size design, seal ring 7 is extruded by stuffing box gland 2 and body 1, and inside and outside stuffing box gland 2, both sides form sealing area 3 and open area 4 respectively; After sealer is dry, body 1 outer wall and open area 4 is cleaned, carries out brush coating according to the distribution of spiral sealing tape 9, finally carry out the coating of epoxy resin.Epoxy resin has excellent corrosion resistance, adhesion and wear-resisting property, effectively resists the corrosion of acidic materials, simultaneously long service life, saves the troublesome operation of regularly japanning.
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.
