Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fitting water pressure test sealing devices, in particular to a three-way pipeline water pressure test sealing device. Background Art

[0002] After the pipeline is processed, it is usually necessary to conduct a water pressure test on the pipe fittings to verify the sealing performance, strength performance, etc. of the pipeline. The traditional test method for three-way pipelines is to weld plugging plates to all the pipe openings of the pipeline. The plugging plates have water inlet holes and drainage holes, and connect the high-pressure water pipe to the holes to complete the water pressure test. This method requires a long preparation time and is not efficient. In addition, the welding effect of the weld needs to be verified before the water pressure test. At the same time, the traditional method is suitable for three-way pipelines with small production batches. Summary of the invention

[0003] The utility model aims to overcome the deficiencies of the prior art and provides a three-way pipeline water pressure test sealing device which has high versatility, good sealing effect, is easy to install and disassemble, and reduces test auxiliary time.

[0004] To achieve the above-mentioned purpose, the utility model provides a three-way pipe water pressure test sealing device, comprising a three-way pipe and a support seat, the three-way pipe is placed in the U-shaped cavity of the support seat; the two side bars and the cross bar of the U-shaped frame on the two sides of the support seat are provided with guide holes, and the two side plugging plates and the edges of the upper plugging plate of the three-way pipe are provided with two support ears, the support ears of the two side plugging plates are fixedly connected to the guide holes of the side bars of the U-shaped frame by locking bolts, and the support ears of the upper plugging plate are fixedly connected to the guide holes of the cross bars of the U-shaped frame by tightening bolts.

[0005] Furthermore, the two supporting ears are arranged symmetrically.

[0006] Furthermore, sealing rings and guide bosses are provided between the upper plugging plate, the plugging plates on both sides and the three-way pipe opening.

[0007] Compared with the prior art, the utility model has the following beneficial effects: the sealing device of the utility model is easy to install and disassemble, has good sealing effect and is easy to install and disassemble, and reduces the auxiliary time of the test; it has high versatility, can be repeatedly recycled, and saves production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 The utility model is a schematic diagram of the structure of a three-way pipeline water pressure test sealing device. DETAILED DESCRIPTION

[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clearer understanding of the present invention, but they do not constitute a limitation on the present invention.

[0010] like Figure 1The three-way pipe water pressure test sealing device shown includes a three-way pipe 1 and a support seat 2. The three-way pipe 1 is placed in the U-shaped cavity of the support seat 2. The inner surface of the U-shaped cavity of the support seat 2 is in contact with the outer cylindrical surface of the three-way pipe 1 to support and fix the three-way pipe 1. The two side bars and cross bars of the U-shaped frame on both sides of the support seat 2 are provided with guide holes 21. The edges of the two side plugging plates 4 and the upper plugging plate 3 of the three-way pipe 1 are provided with two ears. The two ears are symmetrically arranged. The ears of the two side plugging plates 4 are fixedly connected to the guide holes 21 of the side bars of the U-shaped frame through locking bolts 41, and the ears of the upper plugging plate 3 are fixedly connected to the guide holes 21 of the cross bars of the U-shaped frame through tensioning bolts 31. In addition, sealing rings and guide bosses (not shown in the figure) are provided between the upper plugging plate 3 and the two side plugging plates 4 and the mouth of the three-way pipe 1.

[0011] The installation method is as follows: place the three-way pipe 1 on the support seat 2, add a sealing ring to the upper plugging plate 3 and pre-cover the upper end of the three-way pipe 1, tighten the upper plugging plate 3 and the support seat 2 by tightening the bolts 31, so that the upper end of the three-way pipe 1 remains sealed and prevents the support seat 2 and the three-way pipe 1 from moving laterally relative to each other. Pass the locking bolt 41 through the guide hole 21 of the side rod of the U-shaped frame of the support seat to lock the two ears along the edge of the side plugging plate 4 with the support seat 2, so that the two sides of the three-way pipe 1 remain sealed. After the device is assembled, the water inlet hole 5 on the side plugging plate 4 is connected to the high-pressure water pipe, and the water pressure test of the three-way pipe 1 can be carried out. The sealing device is easy to install and disassemble, which shortens the auxiliary work time; and it can be recycled repeatedly to save production costs.
