Clamping hoop connection method of thin-wall metal groove pipeline being thinner than DN50

Abstract

The invention discloses a clamping hoop connection method of a thin-wall metal groove pipeline being thinner than DN50. Stable flexible sealed connection between thin-wall metal pipelines is formed through main parts of a grooved pipeline A, a grooved different diameter pipeline, a grooved pipeline B, a monaural double-ring-buckle clamping hoop connection device, a monaural three-ring-buckle clamping hoop connection device and the like. A pipeline clamping hoop piece adopts punching integrated structure design suitable for volume production, the structure is exquisite, the property is safe andstable, the manufacturing cost is low, mounting is rapid and convenient, the pipeline system is good in stability, and repairing is convenient. A sealing ring is designed by adopting a special structure integrating three-pass sealing functional connection and flexible connection, so that pipeline connection has a good sealing property and flexible stretching and retracting. The technology is lowin manufacturing cost and stable in property, not only conforms to the overall direction of development of a pipeline mounting technique, but also achieves powerful support to popularizing an emerginghome decoration thin-wall metal (containing stainless steel) pipeline mounting market.

Description

technical field [0001] The invention relates to the technical field of connection of liquid and gas delivery pipelines, in particular to a clamp connection method for thin-walled metal pipelines smaller than DN50. Background technique [0002] The grooved pipe fitting connection technology, also known as the clamp connection technology, was invented by Americans in the 1950s. Because the DN50 grooved pipe connection is simple to install, quick to operate, recyclable, and has good stability of the pipe system after installation, it is easy to maintain. The convenience makes this technology popularized and used all over the world soon. Mainland China has introduced grooved pipe fittings connection technology since 1998. After more than ten years of development and application, due to the advancement and maturity of ≥ DN50 grooved pipe connection technology, it was soon accepted by the domestic pipeline installation market. , Widely used in fire-fighting pipelines, water suppl...

AI Technical Summary

Problems solved by technology

[0006] On the basis of retaining the excellent performance of the traditional clamp connection, such as convenient installation, flexible connection and convenient maintenance, the clamp parts abandon the traditional alloy casting structure design and production process, and use the metal plate stamping structure design and production process with low production cost. Reduce the production cost of small pipe clamps by about 75%, solve the cost problem of traditional clamp connectors, significantly improve the cost performance of new clamp connectors, and gain the recognition of the future pipeline installation market
