Description

Technical Field

[0001] The utility model relates to a clamp-type straight-through joint, belonging to the technical field of straight-through joints. Background Art

[0002] Straight-through joints are common joint fittings in pipelines and are widely used in modern life, among which the ferrule-type straight-through joints are the most versatile. Usually, a ferrule-type straight-through joint consists of a joint body and a ferrule. When in use, the pipe fitting is inserted into the end of the joint body, and is connected to the joint body through a ferrule sleeve arranged on the outside of the pipe fitting so that the pipe fitting is fixed in the joint body. Patent No. CN202122495200.7 provides a ferrule-type straight-through joint, which belongs to the field of pipe fitting connection technology. It solves the problem of low connection strength between the ferrule and the pipe fitting in the existing ferrule-type straight-through joint, and the problem that the pipe fitting is easy to fall off. The utility model has the advantages of improving the connection strength between the ferrule and the pipe fitting, maintaining the connection stability between the ferrule and the pipe fitting, and preventing the pipe fitting from falling off.

[0003] The disadvantage of the above-mentioned straight-through connector is that the connection stability between the ferrule and the pipe is achieved through a tensioning structure. However, the problem with this design is that the tensioning structure itself is easily worn by the pipe, resulting in the tensioning force of the tensioning mechanism being unable to be continuously guaranteed. For this reason, we designed a clamp-type straight-through connector. Utility Model Content

[0004] The purpose of the utility model is to provide a clamp-type straight-through connector to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a clamp-type straight-through joint, comprising a straight-through connection section, a first connection head seat, and a second connection head seat, wherein both ends of the straight-through connection section are seamlessly welded to the first connection head seat and the second connection head seat, and a clamp assembly is provided inside the first connection head seat and inside the second connection head seat;

[0006] Each clamp assembly consists of an outer wire hoop, an inner hoop sleeve, a plurality of deformable clamping columns and a pressure-resistant inner ring. The outer wire hoop is assembled inside the first connector seat through the pressure-resistant inner ring transition. The inner hoop sleeve is pressed onto the inner ring of the outer wire hoop through a plurality of deformable clamping columns. The plurality of deformable clamping columns are evenly distributed around the center of the outer wire hoop.

[0007] In the above-mentioned clamp-type straight-through joint, a hollow valve plate is magnetically mounted at the flange of the inner cavity of the straight-through connection section, and a metal filter is mounted in the hollow portion of the hollow valve plate.

[0008] In the above-mentioned clamp-type straight-through joint, two groups of spring connection seats are installed in the inner cavity of the straight-through connection section, and one end of the two groups of spring connection seats is provided with a rubber resistance block.

[0009] In the above-mentioned clamp-type straight-through joint, the other ends of the two groups of spring connection seats are both provided with limiting columns, and the two groups of limiting columns are both embedded in the inner wall holes of the straight-through connection section.

[0010] In the above-mentioned clamp-type straight-through joint, the number of the two groups of limiting pillars and the number of the two groups of spring connecting seats are both four, and the four spring connecting seats and limiting pillars are all annularly distributed structures.

[0011] In the above-mentioned clamp-type straight-through joint, a removal connecting rod is installed in the middle of the metal filter screen, and the removal connecting rod extends to the interior of the second connecting head seat.

[0012] Compared with the prior art, the beneficial effects of the present invention are:
