Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe joints, in particular to a multifunctional stainless steel pipe joint. Background Art

[0002] Stainless steel pipe fittings are components used to connect stainless steel pipes. They are usually made of stainless steel and can be used to connect pipes of the same or different specifications, as well as to connect different parts of the pipe or change the direction. Stainless steel pipe fittings can be divided into many types, including elbows, tees, crosses, flanges, and socket joints. Among them, elbows are used to change the direction of the pipe, tees and crosses are used to divert or merge pipeline fluids, flanges are used to connect pipes and valves or equipment, and socket joints are used to connect the interface between pipes and flanges.

[0003] During the use of the existing stainless steel pipe joints, the pipes on both sides are connected to the joints to connect the two pipes. However, the connection method between the stainless steel pipes and the joints is relatively complicated, and it is troublesome to disassemble during maintenance. Utility Model Content

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0021] like Figure 1-Figure 3As shown, a multifunctional stainless steel pipe joint provided in this embodiment includes a joint 1, both ends of which are connected to a pipe 2, grooves 3 are symmetrically provided on both sides of the joint 1, the grooves 3 are convenient for the movement of a limit ring 401, a limit assembly 4 is arranged in the groove 3, the limit assembly 4 includes a limit ring 401 and a guide rod 402, an outer sheath 5 is installed on the outside of the joint 1, the outer sheath 5 can support the clamping bolt 601, a clamping assembly 6 is symmetrically installed in the outer sheath 5, the clamping assembly 6 includes a clamping bolt 601 and a pressure plate 602, and the position of the clamping assembly 6 corresponds to that of the guide rod 402.

[0022] like Figure 2-Figure 3 As shown, the limit ring 401 is a split semicircular structure, and the end of the limit ring 401 facing the pipe 2 is an inclined structure. The guide rod 402 is installed at the end of the limit ring 401, and the guide rod 402 passes through the joint 1, so that when the pipe 2 is connected, the pipe 2 contacts the inclined surface of the limit ring 401, and the limit ring 401 is forced to move outward.

[0023] like Figure 2 As shown, a thread groove 9 is formed on the outer sheath 5 , and the clamping bolt 601 is rotatably connected to the outer sheath 5 through the thread groove 9 , so that the clamping bolt 601 can be rotated along the outer sheath 5 through the thread groove 9 .

[0024] like Figure 2-Figure 3 As shown, the bottom end of the clamping bolt 601 is connected to the pressure plate 602 through the bearing 8. The pressure plate 602 is located outside the guide rod 402 and can be driven to move through the bearing 8 during the rotation of the clamping bolt 601.

[0025] like Figure 1-Figure 2 As shown, the joint 1 is a double-layer structure, and the pipe 2 is plugged into the joint 1, so that two sets of pipes 2 can be connected through the joint 1.

[0026] like Figure 2-Figure 3 As shown, a guide assembly 7 is installed on the outside of the limiting assembly 4. The guide assembly 7 includes a guide rod 701 and a telescopic spring 702, which facilitates guiding the limiting ring 401 through the guide assembly 7.

[0027] like Figure 2-Figure 3 As shown, the telescopic spring 702 is located outside the guide rod 701, and the guide rod 701 is a telescopic structure. The two ends of the telescopic spring 702 and the guide rod 701 are respectively fixedly connected to the limit ring 401 and the joint 1, so that when the limit ring 401 is moved under force, the limit ring 401 squeezes the telescopic spring 702 and the guide rod 701, and after the pipe 2 is separated from the joint 1, the reaction force of the telescopic spring 702 drives the guide rod 701 and the limit ring 401 to reset.

[0028] Working principle of the device: When the device is used, the staff places the connector 1 at the connection point of the two sets of pipes 2, and inserts the pipes 2 into the two ends of the connector 1 respectively. During the insertion process, the pipe 2 contacts the inclined surface of the limit ring 401, and the limit ring 401 is forced to move outward, and drives the guide rod 402 to move. After the pipe 2 is inserted into the connector 1, the staff rotates the clamping bolt 601 in the clamping assembly 6, and the clamping bolt 601 rotates along the outer sheath 5 through the threaded groove 9. During the rotation of the clamping bolt 601, The bearing 8 drives the pressure plate 602 to move, so that the pressure plate 602 presses down the guide rod 402, and then fixes the limit ring 401, so that the pipe 2 is connected and fixed to the joint 1. The installation method is simple. During the later maintenance, the staff reverses the tightening bolt 601. At this time, the guide rod 402 loses pressure. The staff can pull out the pipe 2 to separate it from the joint 1, which is convenient for later maintenance and disassembly. After the pipe 2 is separated from the joint 1, the reaction force of the telescopic spring 702 drives the guide rod 701 and the limit ring 401 to reset.

[0029] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
