Single-groove double-clamp pipeline clamp connection system

Abstract

The invention discloses a single-groove double-clamp pipeline clamp connection system which comprises a connecting pipes and clamps for tightly connecting every two adjacent connecting pipes. The end of each connecting pipe is provided with a connecting end. The connecting end, close to a pipe orifice, of each connecting pipe is a large-diameter section. A groove is formed in the outer surface the large-diameter section tail end, away from the pipe orifice, of the connecting pipes, and one side, opposite to the large-diameter section, of the groove is a step. The connecting end face of each clamp is provided with a first protrusion and a second protrusion. A concave channel is formed between each first protrusion and each second protrusion, the concave channel is matched with the corresponding step of each connecting pipe, the first protrusion is matched with the groove of the connecting pipes. The clamps are connected in a locked manner through bolts. By the single groove, double clamping seal connection is achieved. In addition, convenience in construction is achieved, reliable pipeline connection is achieved, quite high medium pressure can be transmitted, large pipeline axial pull force can be borne, mounting, demounting and maintaining are facilitated.

Description

technical field [0001] The invention relates to a pipeline connection structure, in particular to a pipeline clamp connection system with a single groove and double clamp structure. Background technique [0002] At present, in the connection of building water supply and fire-fighting pipelines, people will widely use grooved clamps to connect two connecting pipes. However, when the pressure of the medium conveyed by the pipeline is high, the reliability of the traditional grooved clamp connection pipe is very low, especially when the direction of the pipeline is a broken line, the traditional grooved clamp connection pipe is easy to fall off the pipe . Therefore, people will design a double-groove clamp. Although the connection method of the double-groove clamp can avoid the above problems, the processing and production of the double-groove clamp is relatively difficult. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the pr...

However, when the pressure of the medium conveyed by the pipeline is high, the reliability of the traditional grooved clamp connection pipe is very low, especially when the direction of the pipeline is a broken line, the traditional grooved clamp connection pipe is easy to fall off the pipe

Therefore, people will design a double-groove clamp. Although the connection method of the double-groove clamp can avoid the above problems, the processing and production of the double-groove clamp is more difficult.
