Embodiment Construction

[0027] see Figure 1-2 , shows the semi-enveloped sealing pipe joint of the present invention.

[0028] The half-covered sealed pipe joint at least includes an intermediate piece 11 , an abutment piece 12 , a tight hoop piece 13 and an elastic deformation piece 14 .

[0029] The middle piece 11 is the main body connecting the pipes T on both sides, which includes a transition part 111 located in the middle gap of the pipes T on both sides and a first protrusion 113 extending upward from both ends, so as to better provide the entry of the pipe T and wrapping, the middle sides of the inner surface of the intermediate piece 11 respectively extend outward from the transition portion 111 to a wrapping portion 112 inserted into the inside of the tube T.

[0030] Therefore, when the pipe fittings T on both sides are connected, it is only necessary to insert the pipe fitting T into the groove formed by the cladding part 112 to form a stable positioning of the pipe fitting T, without ...

Abstract

A semi-coated sealing pipe joint at least comprises middle pieces, abutting pieces, clamping pieces and elastic deformation pieces. Each middle piece comprises a transition portion in a gap between pipe fittings on the two sides and a first protrusion, the first protrusions extend upwards from the two ends, and the two sides of the middles of the inner surfaces of the middle pieces extend outwards from the transition portions to form coating portions inserted into the inner sides of the pipe fittings. The abutting pieces and the clamping pieces are arranged on the outer sides of the two ends of the middle pieces respectively, second protrusions opposite to the first protrusions are arranged on the inner sides of the abutting pieces, the clamping pieces coat the outer edges of the first protrusions and the outer edges of the second protrusions, and the elastic deformation pieces are arranged between the middle pieces and the abutting pieces. Therefore, the semi-coated sealing pipe joint is simple in structure and convenient to match and operate, various kinds of fit sealing between pipes is achieved, the sealing effect is effectively improved, objects in the pipes are prevented from being leaked out, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of pipe connection, in particular to a half-covered sealed pipe joint. Background technique [0002] With the continuous improvement of people's living standards, there are more and more various infrastructure constructions, which require pipelines to realize the transportation of water, oil, gas, etc., but as people gradually pay attention to the environment, they also hope that such infrastructure constructions can possible reduction of environmental impact. [0003] In the prior art, in order to achieve pipeline fixing and construction, the pipelines need to be connected together, which inevitably requires connection between the pipes through joints. In the connection, it is required to provide a tight connection function, and it is also necessary to ensure No leakage occurs at the joint. [0004] In the prior art, there is a structure in which both ends are connected by connectors, but the leakage of t...
