Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fittings, and in particular relates to a three-way pipe. Background Art

[0002] A tee is a pipe joint with three openings, that is, the tee has one inlet and two outlets or two inlets and one outlet. It is used at the confluence of multiple pipelines. Its main function is to change the direction of the fluid. However, the prior art makes the tee fixed as a whole after installation. If you want to change the upper and lower positions of the outlet after the tee is installed, you need to disassemble the tee and reassemble it, which results in a high labor intensity and reduces the overall work efficiency of the staff.

[0003] Application number "CN202221972860.8" records "a three-way pipe, comprising: a main pipe, on which a plug hole is arranged; an inner saddle, which comprises a first skirt and a connecting pipe, one end of the connecting pipe is connected to the first skirt, the first skirt is close to the inner wall of the main pipe, and the connecting pipe passes through the plug hole; two groups of semicircular outer saddles are symmetrically arranged, and the two groups of semicircular outer saddles are clamped between the connecting pipe and the main pipe."

[0004] The above patent is based on a three-way pipe, with a hole opened on the side wall of the main pipe, and an inner saddle and two sets of semi-circular outer saddles are combined and clamped in the form of a combination. The inner saddle is first passed through the insertion hole from the inside of the main pipe, and then the semi-circular outer saddle is clamped between the connecting pipe of the inner saddle and the outer wall of the main pipe, so that the first skirt of the inner saddle is close to the edge of the insertion hole on the inner wall of the main pipe, thereby realizing the fixing of the pipe at the saddle mouth. The entire structure uses an embedded block to enable the inner saddle to be tightly connected to the inner pipe, without the need to drill holes on the main pipe and directly use bolts to connect at the saddle mouth, which can avoid the airtightness problem caused by drilling holes, thereby further expanding the scope of application of the three-way pipe.

[0005] The above patent adopts the form of a combined clamping connection of an inner saddle and two sets of semi-circular outer saddles. The inner saddle is first passed through the insertion hole inside the main pipe, and then the semi-circular outer saddle is clamped between the connecting pipe of the inner saddle and the outer wall of the main pipe, so that the first skirt of the inner saddle is close to the edge of the insertion hole on the inner wall of the main pipe, thereby realizing the fixing of the pipe at the saddle mouth. The entire structure uses the form of an embedded block to enable the inner saddle to be tightly connected to the inner pipe. There is no need to drill holes on the main pipe and directly use bolts to connect the saddle mouth, which can avoid the airtightness problems caused by drilling holes, thereby further expanding the scope of application of the tee. However, the above device is fixed as a whole for the tee after the installation of the tee. If you want to change the upper and lower positions of the outlet after the installation of the tee, you need to disassemble the tee and reassemble it, which leads to a high labor intensity and reduces the overall work efficiency of the staff.
