Description

Technical Field

[0001] This utility model relates to the field of fire protection pipeline pressure testing tools, specifically a portable fire protection pipeline pressure testing tool. Background Technology

[0002] Water is a natural fire extinguishing agent, abundant in resources, easy to obtain and store, and poses no harm to the ecological environment, either in itself or during firefighting. Therefore, water-based fire suppression systems have been widely adopted. Water-based fire suppression systems include indoor and outdoor fire hydrant systems, automatic sprinkler systems, water curtain systems, and water mist systems. Outdoor fire hydrant systems are the most basic fire protection facilities. Outdoor fire hydrants must be installed in urban planning, residential areas, and enterprises; outdoor fire hydrant systems must also be installed around industrial buildings, civil buildings, storage yards, and storage tanks. A fire hydrant water supply system is a fixed fire suppression system consisting of a fire water supply network; fire hydrant cabinets equipped with fire hydrants, hoses, and nozzles; fire water tanks; fire water reservoirs; and pressurization equipment.

[0003] With the widespread application and long-term operation of water-based fire suppression systems, static pressure testing of their pipe networks, especially remote fire hydrants, has become the most effective means of verifying the operational status of water-based fire suppression systems. Traditional static pressure testing tools for fire hydrants cannot expel the gas inside the testing tool during testing, thus affecting the results of the static pressure test. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a portable fire hydrant network pressure testing tool to solve the technical problem that the current fire hydrant static pressure testing tool cannot discharge the gas inside the testing tool during the test, thus affecting the results of the fire hydrant static pressure test.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a portable fire-fighting pipeline pressure testing tool is designed, including a conical detection tube. One end of the conical detection tube is connected to a connecting pipe. The inner cavity of the connecting pipe is provided with a connecting mechanism. The surface of the conical detection tube is provided with a water pressure gauge and an exhaust mechanism. The exhaust mechanism includes an exhaust pipe connected to the conical detection tube. An exhaust cylinder is connected to the exhaust pipe. A top block is installed at the top of the inner cavity of the exhaust cylinder. Connecting rods are connected to both sides of the bottom end of the inner cavity of the exhaust cylinder. A bottom block is installed between the tops of the two connecting rods. An arc-shaped groove is opened at the opposite end of the top block and the bottom block. An elastic float ball is set in the arc-shaped groove on the bottom block. An air guide pipe is installed in the top block. One end of the air guide pipe is connected to the middle of the top of the arc-shaped groove on the top block. The other end of the air guide pipe is connected to an air outlet pipe.

[0006] Preferably, the connecting mechanism includes a fixing ring installed inside the connecting pipe, and L-shaped locking blocks are installed on both sides of the inner cavity of the connecting pipe, with the two L-shaped locking blocks being symmetrically distributed.

[0007] Preferably, the end of the conical detection tube away from the connecting pipe is connected to a drain pipe, and a manual valve is provided on the exhaust pipe.

[0008] Preferably, a filter screen is installed inside the conical detection tube, and the filter screen is placed inside the conical detection tube between the connecting pipe and the water pressure gauge.

[0009] Preferably, a sealing gasket is installed at one end of the fixing ring near the L-shaped locking block, and the sealing gasket is elastic.

[0010] Preferably, the exhaust pipe passes through the conical detection pipe, and the outer side of the exhaust pipe is provided with external threads, and the exhaust pipe is threadedly connected to the conical detection pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model combines a conical detection tube, a connecting mechanism, an exhaust mechanism, and a water pressure gauge. After connecting to the fire hydrant via the connecting mechanism and opening the fire hydrant valve, water from the fire hydrant enters the conical detection tube. The exhaust mechanism then vents all the air from the conical detection tube. The water pressure of the fire hydrant is then measured using the water pressure gauge, ensuring that all air is expelled from the conical detection tube during the fire hydrant water pressure test, thereby further improving the accuracy of the fire hydrant water pressure test.

[0013] 2. This utility model, through the setting of a filter screen, can filter the water entering the conical detection tube, thereby preventing impurities in the water from entering the water pressure gauge and causing damage to the water pressure gauge or affecting the water pressure test results.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] Example 1: A portable fire-fighting pipeline pressure testing tool, see [link to example]. Figures 1 to 2 The device includes a conical detection tube 1, one end of which is connected to a connecting tube 11. The inner cavity of the connecting tube 11 is provided with a connecting mechanism, which includes a fixing ring 12 installed inside the connecting tube 11. L-shaped locking blocks 13 are installed on both sides of the inner cavity of the connecting tube 11, and the two L-shaped locking blocks 13 are symmetrically distributed. A water pressure gauge 2 and an exhaust mechanism 3 are provided on the surface of the conical detection tube 1. The exhaust mechanism 3 includes an exhaust pipe 36 connected to the conical detection tube 1, and the exhaust pipe 36 is connected to... An exhaust pipe 31 has a top block 32 installed at the top of its inner cavity. Connecting rods 35 are connected to both sides of the bottom end of the inner cavity of the exhaust pipe 31. A bottom block 34 is installed between the tops of the two connecting rods 35. An arc-shaped groove 310 is formed at one opposite end of each of the top and bottom blocks 34. An elastic float 33 is installed within the arc-shaped groove 310 on the bottom block 34. An air guide pipe 38 is installed inside the top block 32. One end of the air guide pipe 38 communicates with the middle of the top end of the arc-shaped groove 310 on the top block 32. The other end of the air pipe 38 is connected to the air outlet pipe 39. During operation, it is aligned with the water outlet of the fire hydrant via the connecting pipe 11 and fitted onto the water outlet of the fire hydrant. Then, the connecting pipe 11 is rotated to connect the conical detection pipe 1 to the water outlet of the fire hydrant using the L-shaped connecting block. Then, the valve of the fire hydrant is opened, so that when the water in the fire hydrant enters the conical detection pipe 1, the water pressure pushes the gas in the conical detection pipe 1 through the exhaust pipe 36 into the exhaust stack 31. Then, the gas is discharged from both sides of the bottom block 34 and both sides of the elastic float 33. When the gas is exhausted, the water in the conical detection tube 1 enters the exhaust pipe 31, and the elastic float 33 floats on the water surface until the elastic float 33 is placed in the arc groove 310 to block the air guide tube 38. Then, the water pressure of the fire hydrant is detected according to the water pressure gauge 2, thereby ensuring that the gas inside the conical detection tube 1 is discharged during the fire water pressure test, further improving the accuracy of the fire hydrant water pressure test. In addition, the conical detection tube 1, water pressure gauge 2 and exhaust mechanism 3 are connected as a whole, which makes it easy for personnel to carry and use.

[0019] For details, see Figure 1 The end of the conical detection tube 1 away from the connecting pipe 11 is connected to a drain pipe 4. A manual valve 41 is provided on the exhaust pipe 36. When the fire hydrant is tested for water pressure, the drain pipe 4 is closed by the manual valve 41 to prevent the water tested by the fire hydrant from being discharged through one end of the conical detection tube 1. After the water pressure test is completed, the manual valve 41 is opened to facilitate the discharge of the water remaining inside the conical detection tube 1 after use.

[0020] Further, see Figure 1 The inner cavity of the conical detection tube 1 is equipped with a filter screen 5. The filter screen 5 is placed in the inner cavity of the conical detection tube 1 between the connecting pipe 11 and the water pressure gauge 2. By setting the filter screen 5, the water entering the conical detection tube 1 can be filtered, thereby preventing impurities in the water from entering the water pressure gauge 2 and causing damage to the water pressure gauge 2 and affecting the water pressure test results of the water pressure gauge 2.

[0021] It is worth noting that, see Figure 1 A sealing gasket 14 is installed at one end of the fixing ring 12 near the L-shaped locking block 13, and the sealing gasket 14 is elastic. By setting the sealing gasket 14, the sealing effect of the connection between the conical detection tube 1 and the fire hydrant is increased, so that water leakage when the conical detection tube 1 is used will affect the water pressure test results.

[0022] It is worth mentioning that, see Figure 2 The exhaust pipe 36 passes through the conical detection pipe 1. The outer side of the exhaust pipe 36 is provided with an external thread 37. The exhaust pipe 36 is threadedly connected to the conical detection pipe 1. The external thread 37 facilitates the disassembly and assembly of the exhaust cylinder 31, and further facilitates the disassembly and replacement of the damaged exhaust mechanism 3.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
