Abstract

The utility model discloses a combined clamp, which relates to the technical field of flange plugging, and comprises a plurality of spliced clamp assemblies, wherein the clamp assemblies are composed of a first bracket and a second bracket, the first bracket and the second bracket are both provided with locking nuts, the locking nuts on adjacent clamp assemblies are connected and fixed by locking bolts, and the clamp plane and the flange are tightly combined by changing the angle of the first bracket and the second bracket and increasing or decreasing the number of clamp assemblies, so as to solve the problem that when a square or triangular flange is leaking, a plugging device is subjected to uneven force and a blind spot exists in the compressed plugging filler.

Description

Combined clamp

Technical Field

The utility model relates to the technical field of flange plugging, in particular to a combined fixture.

Background

Pressurized plugging is a common means for solving the problem of leakage. The leakage solved by the teaching means can be avoided within six months or years. Especially for the fluid medium of chemical enterprises and other enterprises, the fluid medium can not be stopped in time in the daily operation process, and the stop accident caused by leakage can be effectively solved. When the flange is used for plugging under pressure, the plugging sealant under pressure is selected in many cases, so that the selection is very important because the production process is not influenced.

The pressurized plugging mode generally requires manufacturing and installing a fixture so as to plug under pressure, and then injecting special sealant for pressure plugging into the fixture through a special glue injection tool to form compact filler and new seal. Circular flanges are most commonly used, square flanges and triangular flanges facilitate compact tube alignment, and oval flanges are commonly used on valves and small diameter high pressure tubes. The low-pressure circular flange leakage can be plugged by using a stainless steel hose clamp or a self-made circular fixture. However, the low-pressure square flange or the triangular flange is leaked and recycled in the traditional plugging mode, and the clamp plane cannot be tightly combined with the flange due to uneven stress points and advanced stress of flange angles.

Disclosure of utility model

The utility model provides a combined fixture, which aims to overcome the defect that in the prior art, a low-pressure square flange or a triangular flange is not uniform in plugging stress point and the flange angle is stressed in advance, so that the plane of the fixture cannot be tightly combined with the flange.

The technical scheme adopted for solving the technical problems is as follows: the combined clamp comprises a plurality of clamp components which are spliced and combined, wherein each clamp component is formed by connecting a first bracket and a second bracket, locking nuts are arranged on the first bracket and the second bracket, and the locking nuts on adjacent clamp components are connected and fixed through locking bolts.

As a further improvement of the utility model, the end of the first bracket forms an included angle of 135 degrees with the horizontal, and the end of the second bracket forms an included angle of 45 degrees with the horizontal.

As a further improvement of the utility model, gaskets are arranged at the end parts of the first bracket and the second bracket, so that good sealing performance is ensured.

As a further improvement of the utility model, the inner side of the fixture component is provided with a sealing component, so that good sealing performance is ensured.

As a further development of the utility model, the angle between the first and the second support is 90 °.

As a further development of the utility model, the angle between the first and the second support is 60 °.

Compared with the prior art, the utility model has the beneficial effects that: according to the scheme, the number combination of the clamp assemblies is increased or reduced by changing the angles of the first support and the second support, so that the clamp plane and the flange are tightly combined, and the defect that the plugging device is unevenly stressed and compacts plugging fillers to have blind areas when the square or triangular flange is used for treating leakage is overcome.
