Abstract

The present invention relates to a clamp for repairing a hole when a hole is generated in the elbow (111) portion of the pipe fittings, rod washers (13a, 13b) and the nut (14a, locking device on both opposite ends) 14b) and a sealing sleeve 17 which is provided symmetrically with bolts 12a and 12b and is cut to surround the elbow 111 on the inner surface of the body and the case 10a or 10b having a slide portion 15a15b at one end thereof. In the clamp consisting of, the sealing sleeve 17 is pressed to prevent the leakage due to the fastening of the bolts (12a, 12b) of the locking device is used as the elbow leakage repair clamp (16 in Figure 3). , The general welding part (16 in Figure 4) is to be used in the leaking part.

Description

Repair clamp for leak of Elbow

The elbow part of the general pipe line is subject to the most pressure, so corrosion progresses quickly. The elbows are more easily leaked than other parts because the outer wall becomes thinner during manufacture.

The present invention is designed to repair the leak in the elbow portion,

As is well known, the elbow portion 111 has a curved surface unlike the straight pipe 112, which is very difficult to clamp, but the width and the size of the end portions 11a and 11b of the clamp cases 10a and 11b, and sealing. Since the crimping is possible according to the shape and thickness of the sleeve 17, referring to the drawings as shown in the representation.

In order to repair the elbow 111 in the prior art, the rubber tube and rubber gloves are cut as shown in FIG. 13 to cover the perforated pores 16, or after removing the contents of the pipe, wrap the chemically treated bandage and leak it. In the case of repairing parts (Fig. 13) and plumbing materials (Fig. 15) of the entire elbow type produced in the US (Fig. 15), a single 50A USD $ 1,5O0 may be purchased. Its shape is slightly different from Figure 15) It has a lot of weight and its structure is difficult to use because of its complexity.

However, it is not inconvenient to stop the production line, remove water, oil, steam, chemicals, etc. from the pipe and weld.

In the present invention, the elbow portion is made of a curved surface unlike the straight pipe, so it is possible to minimize the width of the clamp. Therefore, the clamp lock bolt 12 must be made at one end, and both ends of the clamp 11a and 11b. ) Is wrapped so that the sealing sleeve 17 is not protruded or detached from both ends of the case (11a, 11b) at the time of compression, but if the sealing sleeve (17) is wrapped around it can not be compressed due to both ends of the clamp (Fig. 14) of the sealing sleeve Only part of both ends 11a and 11b should be wrapped so that sufficient compression can be applied.

At this time, if the sealing sleeve is made to the right angle to the curved surface, when the sealing sleeve 17 is crimped, and protrudes to the outside, as shown, the shape of the sealing sleeve should be configured with an inclination 18 so that sufficient compression is possible.

Therefore, the method of the present invention is to unfasten the bolt locking device first and then open the incision sealing sleeve 17 to wrap in the perforations (16) of the elbow, and then tighten the case can be completed all the maintenance work within 5 to 10 minutes. .

The piping line of such an industrial facility is like a blood vessel of the human body, so it is an object of the present invention to make it easy to repair in a short time without stopping production.
