Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a clamp with self-lubricating ability to solve the problem of uneven distribution of clamping force in existing clamps. The result of uneven distribution of clamping force is poor sealing. This will seriously affect the application effect of the V-shaped clamp. When leakage occurs, the parts need to be repaired or reworked, which increases the cost of use.

Abstract

The invention provides a clamp with self-lubricating capacity, belongs to the technical field of pipeline connection, and aims to solve the problems that an existing clamp is uneven in clamping force distribution, poor sealing is generated due to uneven clamping force distribution, the application effect of a V-shaped clamp is seriously affected, and when leakage occurs, the V-shaped clamp is damaged. The device comprises an outer clamping piece, an inner clamping piece, an outer clamping piece, a clamping piece and an inner clamping piece, the outer clamping piece is of an arc-shaped strip-shaped structure. And the inner pressing pieces are of a multi-section structure, the multiple sets of inner pressing pieces are arranged in the outer clamping piece in a circumferential array mode, the inner pressing pieces and the outer clamping piece are connected in a spot welding mode, and the inner pressing pieces are of a V-shaped structure. According to the invention, surface pressure on a connected piece is more fully and uniformly converted, the total axial clamping force is also greatly improved, the clamping force is more uniform, good connection strength and sealing performance are ensured, the problem of untight sealing of a pipeline is greatly reduced, and the repair and maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection, and more specifically relates to a clamp with self-lubricating ability. Background technique [0002] V-shaped clamps can be used in heavy-duty occasions. Using V-shaped clamps can easily connect the connected parts together, and it can be disassembled, which provides convenience for maintenance. This component can be widely used in various Various fields, such as: automotive exhaust system, fluid delivery, connection of components, etc. [0003] Based on the above, the existing clips have the disadvantage of uneven distribution of clamping force. The consequence of uneven distribution of clamping force is poor sealing, which will seriously affect the application effect of V-shaped clamps. When leakage occurs, it is necessary to Repairing or reworking the components increases the cost of use. [0004] Therefore, in view of this, research and improvement are made on the existing stru...
