Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting pipelines, in particular to a pipeline connection device for fire-fighting pipelines. Background Technique

[0002] Fire-fighting pipelines refer to pipeline materials used for fire-fighting, connecting fire-fighting equipment and devices, and conveying fire-fighting water, gas or other media. Due to special requirements, the thickness and material of fire-fighting pipelines have special requirements, and they are painted with red paint and convey fire-fighting water. Fire-fighting pipelines are an important part of the fire-fighting system.

[0003] Traditional fire-fighting pipelines usually connect the two ends of the pipelines by using flanges and screws. The joints of the flanges are potential leakage points, especially water leakage may occur in high-pressure or high-temperature environments. Since water is colorless and tasteless, slight water leakage cannot be detected in time. Therefore, a pipeline connection device for fire-fighting pipelines is proposed to solve the above-mentioned problems. Content of the Utility Model

[0004] (1) Solved Technical Problems

[0005] Aiming at the deficiencies of the prior art, the utility model provides a pipeline connection device for fire-fighting pipelines, which has the advantages of leakage detection, etc., and solves the problems that the joints of the flanges are potential leakage points, especially water leakage may occur in high-pressure or high-temperature environments, and slight water leakage cannot be detected in time due to the colorless and tasteless state of water.

[0006] (2) Technical Solutions

[0007] The technical solution of the utility model to solve the above technical problems is as follows: A pipeline connection device for fire-fighting pipelines includes a fire-fighting pipeline body. The number of the fire-fighting pipeline bodies is two and they are symmetrically distributed left and right. Flanges are fixedly connected to the outer sides of the two fire-fighting pipeline bodies. Six first screws are threadedly connected to the inside of each of the two flanges and are distributed in a circular array. Fixing rings are sleeved on the outer sides of the two fire-fighting pipeline bodies. Six second screws are threadedly connected to the inside of each of the two fixing rings and are distributed in a circular array. The outer sides of the two flanges are sleeved with the same water-absorbing ring. Two color-changing paper rods are inserted into the inside of the right fixing ring and are symmetrically distributed up and down. The left sides of the two color-changing paper rods are in contact with the right side of the water-absorbing ring.

[0008] The beneficial effects of the present utility model are as follows: Six first bolts fix the two fire pipeline bodies in the first step through two flanges. Six second screw rods provide further fixing effects for the two fire pipeline bodies through two fixing rings and two flanges. The water absorption ring can absorb the water flowing out from the joint of the two flanges and transfer it to the two color-changing paper rods. After the two color-changing paper rods absorb water, they change color, which is convenient to discover whether there is water leakage from the colors of the two color-changing paper rods.

[0009] The pipeline connecting device for the fire pipeline has the advantage of leakage detection.

[0010] On the basis of the above technical solution, the present utility model can be further improved as follows.

[0011] Further, a number of six grooves are provided on the inner sides of the two fixing rings and are distributed in an annular array. The twelve grooves are adapted to the six first screw rods.

[0012] The beneficial effect of adopting the above further solution is that the twelve grooves can prevent the six first screw rods from pressing against the two fixing rings and making it inconvenient for the two fixing rings to fit together.

[0013] Further, a number of four card holes are provided on the outer sides of the two fixing rings and are distributed in an annular array. Four U-shaped blocks are inserted into the eight card holes and are distributed in an annular array.

[0014] The beneficial effect of adopting the above further solution is that the four U-shaped blocks can provide further limiting effects for the two fixing rings through the eight card holes.

[0015] Further, two transparent acrylic protective covers are fixedly connected to the right side of the right fixing ring and are distributed symmetrically up and down. The two transparent acrylic protective covers are respectively adapted to the two color-changing paper rods.

[0016] The beneficial effect of adopting the above further solution is that the two transparent acrylic protective covers can prevent the water from the outside from sticking to the color-changing paper rods and causing the color-changing paper rods to change color.

[0017] Further, a first sealing gasket is sleeved on the outer sides of the two fire pipeline bodies, and the two first sealing gaskets are respectively adapted to the two fixing rings.

[0018] The beneficial effect of adopting the above further solution is that the first sealing gasket can increase the sealing performance between the two fixing rings and the two flanges.

[0019] Further, a second sealing gasket is fixedly connected to the right side of the left flange, and a sealing groove adapted to the second sealing gasket is provided on the left side of the right flange.

[0020] The beneficial effect of adopting the above further solution is that the second gasket can increase the sealing performance between the two flanges. Brief Description of the Drawings
