Description

High temperature resistant clamp

Technical Field

The utility model relates to a clamp.

Background

V-clamps typically have a band, a plurality of liners, T-bolts, T-sleeves, and self-locking nuts. The band is bent into a C-shape. After the heads of the two ends of the strap are rolled up, a cross rod of the T-shaped bolt and a transverse pipe of the T-shaped sleeve are respectively penetrated, and the head of the strap is fixed by spot welding to ensure that the T-shaped bolt and the T-shaped sleeve are fixed and can bear tension or pressure. The lining plate is spot-welded on the hoop belt, the vertical rod of the T-shaped bolt penetrates through the vertical pipe of the T-shaped sleeve and then is in threaded connection with the self-locking nut, the hoop can be pre-tightened by rotating the self-locking nut, and finally the flange is tightened to achieve the sealing effect.

With the coming implementation of the national emission standard, the requirement on the temperature resistance of the V-shaped clamp for flange connection is higher and higher. To make V type clamp satisfy high temperature resistance requirement, except that selecting for use high temperature resistant material, because the pipeline of installation V type clamp is high temperature environment, and the welt is direct and pipeline contact, receives the temperature influence great, therefore the structure of welt also greatly influences the high temperature resistance ability of clamp. The contact area of the lining plate of the existing V-shaped clamp and a pipeline flange is large, heat conduction is increased, the temperature is increased, the high-temperature resistance is not achieved, the mechanical performance of the high-temperature-resistant clamp is easy to reduce when the clamp works in a high-temperature environment, and even the accident that the clamp is broken occurs.

Disclosure of Invention

The utility model aims to solve the technical problem that a high temperature resistant clamp is provided, its simple structure has good high temperature resistance.

In order to solve the above technical problem, an embodiment of the present invention provides a high temperature resistant clamp, including a strap and a plurality of lining plates; the lining plates are arranged at intervals and are respectively connected with the inner wall of the strap; each lining plate comprises a top wall and a pair of side walls, and the top ends of the pair of side walls are respectively connected with the two opposite sides of the top wall; the inner surfaces of the pair of side walls are provided with a plurality of bulge parts bulging inwards at intervals along the length direction of the side walls, and the bulge parts of one side wall and the bulge parts of the other side wall are arranged in a one-to-one correspondence mode.

After the technical scheme is adopted, the utility model discloses following advantage and characteristics have at least:

the high temperature resistant clamp of this embodiment has a plurality of welts that set up at intervals each other, the internal surface of a pair of lateral wall of each welt all is equipped with the uplift of a plurality of inside uplifts, uplift centre gripping pipeline flange through a pair of lateral wall, leave the gap between a pair of lateral wall and the pipeline flange by the centre gripping, thereby the area of contact of welt and pipeline flange has been reduced, the area of crossing the wind and the amount of wind of clamp have been increased, the temperature rise that the heat transfer caused has been reduced, make the radiating effect and the high temperature resistance performance of clamp obviously improve, and improved welt anti deformability.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Please refer to fig. 1 and fig. 2. According to the utility model discloses a high temperature resistance clamp, including strap 1, a plurality of welt 2, T type sleeve 3, T type bolt 4 and self-locking nut 5.

The band 1 is bent into a C-shape. After the two ends of the strap 1 are curled, the cross rod 41 of the T-shaped bolt 4 and the transverse pipe 31 of the T-shaped sleeve 3 are respectively penetrated, and the T-shaped bolt 4 and the T-shaped sleeve 3 are fixed by spot welding at the head of the strap 1 and can bear tension or pressure. The vertical rod 42 of the T-shaped bolt 4 passes through the vertical pipe 32 of the T-shaped sleeve 3 and then the clamp is screwed by the self-locking nut 5.

In this embodiment, the number of the lining plates 2 is three, the lining plates 2 are spaced apart from each other, and the lining plates 2 are connected to the inner wall of the band 1. In other embodiments, the number of the liner plates 2 may be three or more. Alternatively, the lining panels 2 are evenly distributed along the circumference of the band 1, the length of the lining panels 2 being equal. The lining plates 2 are connected to the inner wall of the band 1 by spot welding.

Please refer to fig. 3 and 4. The lining plate 2 is arc-shaped. The liner 2 includes a top wall 21 and a pair of side walls 22. The top ends of the pair of side walls 22 are connected to the opposite sides of the top wall 21, respectively. The inner surfaces 22b of the pair of side walls 22 are each provided with a plurality of inwardly bulging portions 221 at intervals along the longitudinal direction of the side wall, and the plurality of bulging portions of one side wall and the plurality of bulging portions of the other side wall are arranged in one-to-one correspondence.

In the present embodiment, each of the ridge portions 221 is formed by the outer surface 22a of the side wall 22 being recessed inward of the side wall 22, so that the outer surface 22a of the side wall 22 has a recessed portion 222 at a position corresponding to the ridge portion 221. This structure is easy to manufacture and saves material.

Alternatively, the plurality of ridges 221 of each sidewall are disposed at equal intervals. The ridges 221 on the same sidewall have equal ridge heights to allow the clamped pipe flange to be uniformly stressed. The ridge height here refers to the distance between the top 221a of the ridge portion 221 and the inner surface 22b of the side wall 22.

Alternatively, the top 221a of each protrusion 221 is a plane, but is not limited thereto, and in other embodiments, the top 221a of the protrusion 221 may also be a circular arc surface.

The high temperature resistant clamp of this embodiment has a plurality of welts that set up at intervals each other, the internal surface of a pair of lateral wall of each welt all is equipped with the uplift of a plurality of inside uplifts, uplift centre gripping pipeline flange through a pair of lateral wall, leave the gap between a pair of lateral wall and the pipeline flange by the centre gripping, thereby the area of contact of welt and pipeline flange has been reduced, the area of crossing the wind and the amount of wind of clamp have been increased, the temperature rise that the heat transfer caused has been reduced, under the condition of guaranteeing flange leakproofness, make the radiating effect and the high temperature resistance performance of clamp obviously improve, and the resistance to deformation of welt has been improved.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
