[0002] The most common situation of damage to enameled equipment is: damage to the enamel of the pipe mouth of the enameled equipment. At present, there are various repair materials and methods for damaged enameled pipe mouths, mainly Bellzona repair method, Zotec repair method, Hastelloy plus repair method or other adhesive repair methods. In actual use, Bellzona repair method and Zotec repair method are commonly used. When a large area is repaired, Hastelloy covering method will be used for repair. The above repair methods are all adhesive repairs. When using the above repairs, due to the different media in the equipment and the changes in equipment temperature and pressure, the adhesive is prone to fall off, dissolve, pressure damage, etc. after repair. And because of the different adhesives used, the time for normal use after repair varies, but the overall effect is not good, and repairs are more frequent. Utility Model Content

[0003] The utility model aims to provide a pipe orifice repair structure for enamel equipment in view of the problems existing in the prior art, which can effectively eliminate the problems of adhesive easily falling off, swelling and pressure damage, thereby extending the service life of the device after repair.

[0004] To this end, the technical solution adopted by the utility model is: a pipe orifice repair structure for enamel equipment,

[0005] The invention comprises a repair pipe, which comprises an installation section and an insertion section. The insertion section can be inserted into a pipe opening to cover a damaged part of the pipe opening, and the outer diameter of the insertion section matches the inner diameter of the pipe opening. A sealing structure for ensuring sealing is arranged between the insertion section and the pipe opening, and the outer diameter of the installation section is between the outer diameter of the insertion section and the inner diameter of the sealing surface of the pipe opening.

[0006] As a preferred embodiment of the above scheme, the sealing structure includes at least two spaced grooves circumferentially arranged on the insertion section, each groove is equipped with a sealing ring, and the depth of the groove is between the radius and diameter of the sealing ring, and the width of the groove is not greater than the diameter of the sealing ring.

[0007] Further preferably, the sealing structure includes a sealing section arranged on one end of the insertion section away from the installation section, the outer diameter of the sealing section is larger than the inner diameter of the pipe mouth, and at least one opening is radially arranged on the sealing section, and a transition cone surface is arranged between the sealing section and the insertion section.

[0008] Further preferably, one end of the sealing section away from the insertion section is configured as a tapered section.

[0009] More preferably, the repair pipe is made of a material that is resistant to high and low temperatures, chemical corrosion, and low permeability.

[0010] More preferably, the repair tube is made of polytetrafluoroethylene.

[0011] The beneficial effects of the utility model are as follows: repair is performed by using a repair tube inserted into the pipe mouth. Since the repair tube can cover the damaged area, compared with the prior art, no adhesive is used, so the adhesive can be effectively prevented from easily falling off, swelling and pressure damage, thereby extending the service life of the repaired equipment; at the same time, a sealing structure is provided in the insertion section, and when the pipe mouth is connected to other equipment, the installation section is pressed to form a seal, so the sealing effect is good, avoiding the problem of uneven sealing surface during adhesive repair.

[0015] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0016] like Figure 1-Figure 3 As shown, a pipe orifice repair structure for an enamel equipment mainly includes a repair pipe 1, and the repair pipe 1 includes a mounting section 1b and an insertion section 1a, wherein the insertion section 1a can be inserted into the pipe orifice 2 to cover the damaged part of the pipe orifice 2, and the outer diameter D of the insertion section 1a is a It matches the inner diameter d1 of the pipe mouth 2, and a sealing structure is provided between the insertion section 1a and the pipe mouth 2 to ensure sealing.

[0017] In order to ensure that the installation section does not affect the installation between the components installed on the pipe nozzle and the pipe nozzle, the outer diameter of the installation section 1b is between the outer diameter of the insertion section 1a and the inner diameter of the sealing surface of the pipe nozzle 2, that is, the outer diameter of the installation section is not greater than the distance between the two installation holes on the pipe nozzle that are located on the same diameter and are used to install bolts. Figure 3 As shown, D b When a recess for installing a seal is provided at the pipe mouth, the thickness of the installation section is greater than the depth of the recess, so that when the corresponding parts are fixed to the flange of the pipe mouth by bolts, the installation section is pressed on the pipe mouth, so that a second seal can be formed, while also ensuring the flatness of the sealing surface.

[0018] The sealing structure may include at least two grooves 1c arranged at intervals on the insertion section 1a in the circumferential direction, each groove 1c is equipped with a sealing ring 3, and the depth of the groove 1c is between the radius and the diameter of the sealing ring 3, and the width of the groove 1c is not greater than the diameter of the sealing ring 3, so that when the sealing ring is sleeved in the groove, the outer ring of the sealing ring exceeds the groove, so that when installed, the outer ring of the sealing ring can contact the inner diameter of the pipe mouth. Preferably, the sealing ring adopts an O-type polytetrafluoroethylene sealing ring, and the inner diameter of the sealing ring is slightly smaller than the bottom diameter of the groove, so that the sealing ring is tightly sleeved in the groove.

[0019] The sealing structure may also include a sealing section 1d disposed on the end of the insertion section 1a away from the installation section 1b, the outer diameter of the sealing section 1d is larger than the inner diameter of the pipe opening, and at least one opening 1e is radially disposed on the sealing section 1d. Preferably, a transition conical surface 1f is disposed between the sealing section 1d and the insertion section 1a, and the end of the sealing section 1d away from the insertion section 1a is disposed as a tapered section 1g. Of course, in addition to the above structure, other sealing structures may also be used.

[0020] To extend the service life, the repair tube 1 is made of a material that is resistant to high and low temperatures, chemical corrosion, and low in permeability, preferably a PTFE material. When the repair tube of the present application is used for repair, adhesive can be applied between the outermost sealing ring and the installation section on the insertion section, or adhesive can be applied on the step between the installation section and the insertion section.
