Embodiment Construction

[0014] Such as Figure 1-4 As shown, a hose joint is a new type of pipe joint of the present invention. The pipe joint is made of NiTi alloy as the base material, mainly NiTiNb8.8 alloy, and its diameter is compatible with the diameter of the connected pipe. The requirements of the connecting pipe are made into various specifications. The inner diameter of the pipe joint body is within the range of ф5-98mm, the length is within the range of 8-190mm, the thickness of the pipe wall is 1mm-3mm, and the inside and outside of the pipe are smooth.

[0015] Such as Figure 3-4 As shown, after the pipe joint is selected to be suitable for the pipe diameter of the connected pipe, the wide hysteresis performance of the NiTi alloy is used, and a large amount of interference is formed between the pipe joint 1 and the connected pipes 2 and 3 by using the memory effect. To fit, first align the diameter of the connected pipe in the pipe joint, and then firmly connect the two connected pipe ...

Abstract

The invention relates to a novel pipe joint. A NiTi alloy is adopted as a base material to prepare a pipe joint body for the pipe joint, the wall thickness of the pipe joint body is 1mm-3mm; the internal and external parts of the pipe joint body are of smooth structures; the pipe inner diameter adapts to the pipe diameter of a connected pipe; and the inner diameter of the pipe joint body is within the range of Phi 5-98mm, and the length of the pipe joint body is within the range of 8-190mm. The novel pipe joint provided by the invention has the beneficial effects that the novel pipe joint abandons the characteristic of poor seal property for the former stainless steel and other joints, and has the advantages of high connection strength, good seal property, abrasion resistance, convenience in operation, light weight, small space and the like.

Description

technical field [0001] The invention relates to a new type of pipe joint. Background technique [0002] The pipe joints of traditional hydraulic and pneumatic pipelines are mostly made of stainless steel, and are often connected by welding, bonding or mechanical threads. Although it can be seen that the two parts are effectively connected, the connection strength is lower than that affected by external impacts, and the inside of the pipe The transported liquid or gas has a certain pressure, and often leaks due to poor sealing, making the corresponding mechanical equipment unable to work normally or causing major accidents, and it is also inconvenient to assemble during the actual installation process. Contents of the invention [0003] The purpose of the present invention is to provide a new type of pipe joint to solve the problem of poor sealing and easy leakage of existing stainless steel pipe joints used to transport hydraulic pressure or gas, which makes the machine un...
