Description

Technical Field

[0001] The utility model belongs to the technical field of fire detection, and relates to a fire pipeline pressure detection device. Background Art

[0002] A fire pipeline refers to pipeline materials used for fire protection, connecting fire-fighting equipment and appliances, and conveying fire-fighting water, gas or other media. Due to special requirements, the thickness and material of fire pipelines have special requirements. Since fire pipelines are often in a static state and have certain pressure requirements inside, it is necessary to design a fire pipeline pressure detection device to conveniently detect whether the pressure inside the fire pipeline meets the standard. Summary of the Invention

[0003] The purpose of the utility model is to address the above problems existing in the prior art and propose a fire pipeline pressure detection device.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A fire pipeline pressure detection device includes an annular main body. It is characterized in that both sides of the annular main body are provided with a water inlet and a water outlet. A snap structure matching the fire water pipe is provided at the water inlet, and a slot structure identical to the original fire water pipe joint is provided at the water outlet. A valve I is rotatably installed inside the annular main body, and a switch I corresponding to the valve is provided outside the annular main body. A pressure gauge is installed on the top of the annular main body. An L-shaped drain pipe is also communicated with the side of the annular main body. A valve II is installed inside the drain pipe, and the valve II is connected with a corresponding switch II. The water outlet of the drain pipe is vertically downward.

[0005] The working principle of the utility model is as follows: The annular main body is installed at the water outlet of the fire water pipe to be detected through the snap structure. Usually, both valve I and valve II are in a normally closed state. After opening the fire water pipe, the pressure inside the fire water pipe at rest can be detected through the pressure gauge. When we need to detect the pressure during water supply of the fire water pipe, valve II can be further opened to lead the water out through the L-shaped drain pipe. At this time, the pressure gauge shows the pressure during water supply. After the detection is completed, valve II is closed, and the annular main body is removed after the fire water pipe is closed. In addition, the annular main body can also not be removed. When the fire water pipe needs to be used later, directly connect the slot structure of the annular main body to replace the original water outlet, and realize the opening and closing of water supply through valve I.

[0006] A number of protrusions are arranged inside the L-shaped drain pipe.

[0007] Adopting the above structure can slow down the impact force of part of the water and reduce the splashing when the water flows out.

[0008] The L-shaped drain pipe adopts a pipe with the same material and thickness as the annular main body.

[0009] With the above structure, the overall compression performance is ensured.

[0010] Sealing rings are installed on both the first valve and the second valve.

[0011] With the above structure, the sealing performance is ensured.

[0012] The pressure gauge is arranged between the first valve and the water inlet.

[0013] With the above structure, it is ensured that the pressure gauge can normally measure the pressure of the fire hose when it is static.

[0014] Compared with the prior art, the fire pipeline pressure detection device has the following advantages: by setting a detachable pressure gauge structure, while ensuring the measurement effect, the device can be permanently installed at the water outlet of the fire pipeline for pressure monitoring according to actual needs, or it can be removed after the pressure detection is completed, realizing multiple and rapid pressure detections.

[0019] As Figure 1-2 shown, the fire pipeline pressure detection device of the present utility model includes an annular main body 1. The two sides of the annular main body 1 are set as a water inlet and a water outlet. A buckle structure 2 matching the fire hose is arranged at the water inlet, and a slot structure 3 the same as the original fire hose joint is arranged at the water outlet. A first valve 4 is rotatably installed in the annular main body 1, a first switch 5 corresponding to the valve is arranged on the outer side of the annular main body 1, a pressure gauge 6 is installed on the top of the annular main body 1, an L-shaped drain pipe 7 is also communicated on the side of the annular main body 1. A second valve 8 is installed in the drain pipe, a second switch 9 corresponding to the second valve 8 is connected, and the water outlet of the drain pipe is arranged vertically downward.

[0020] In the present utility model, both the buckle structure 2 and the slot structure 3 adopt existing fire hose connection structures.

[0021] In the present utility model, valve 1 4 and valve 2 8 are butterfly valves, and other types of valves can be replaced according to actual needs.

[0022] In the present utility model, switch 1 5 and switch 2 9 are switch components matching the structure of the butterfly valve.

[0023] In the present utility model, the pressure gauge 6 uses an existing product for water pressure detection.

[0024] A number of protrusions 10 are provided inside the L-shaped drain pipe 7.

[0025] In the present utility model, the protrusions 10 are made of the same material as the L-shaped drain pipe 7.

[0026] The L-shaped drain pipe 7 is a pipe made of the same material and thickness as the annular main body 1.

[0027] In the present utility model, a collecting bucket can be placed below the drain pipe to collect the discharged water.

[0028] Sealing rings are installed on both valve 1 4 and valve 2 8.

[0029] In the present utility model, the sealing rings use existing sealing rings for valves, and corresponding sealing ring structures are also installed at the water inlet and outlet.

[0030] The pressure gauge 6 is arranged between valve 1 4 and the water inlet.

[0031] The working principle of the present utility model: The annular main body 1 is installed at the water outlet of the fire hose to be detected through the buckle structure 2. Usually, both valve 1 4 and valve 2 8 are in the normally closed state. After opening the fire hose, the internal pressure of the fire hose at rest can be detected through the pressure gauge 6; when we need to detect the pressure of the fire hose during water supply, valve 2 8 can be further opened to lead the water out from the L-shaped drain pipe 7. At this time, the pressure gauge 6 shows the pressure during water supply. After the detection is completed, valve 2 8 is closed, and then the annular main body 1 is removed after the fire hose is closed; in addition, the annular main body 1 can also not be removed. When the fire hose needs to be used later, the slot structure 3 of the annular main body 1 is directly connected to replace the original water outlet, and the opening and closing of the water supply are realized through valve 1 4.
