Description

Technical Field

[0001] The utility model relates to the technical field of fire detection equipment, in particular to a fire hydrant system water testing device for fire detection. Background Art

[0002] The fire hydrant system water testing device, also known as the fire hydrant pressure measuring joint, is used by the fire detection department to measure the pressure of the fire hydrant system in order to accurately judge the performance of the fire hydrant system. It is a special device for calibrating the water column filled by the water gun. During the measurement process, the pressure measuring joint needs to be assembled to the fire hydrant joint to be tested to measure the pressure index.

[0003] When connecting the pressure measuring joint and the fire hydrant joint, in the prior art, such as application number 202321572374.1, and application name "A fire hydrant system water testing device for fire detection", the clamp is often fixed with bolts and nuts, and the two joints are connected with the clamp. Although this method is convenient for connection, it is difficult to apply extrusion force between the two joints during installation. Therefore, even if there is a sealing gasket, it is difficult to extrude and fix the sealing gasket. Therefore, during water testing, water will still flow out through the interface between them, resulting in inaccurate water test pressure.

[0004] For this purpose, a fire hydrant system water testing device for fire detection is proposed. Utility Model Content

[0024] like Figure 1-4As shown, a water testing device for a fire hydrant system for fire detection includes a water testing joint pipe 1 and a detection fire pipe 4, one end of the detection fire pipe 4 is connected to a connecting ring 401, and a connecting member 5 for connecting the detection fire pipe 4 is provided on the water testing joint pipe 1, and the connecting member 5 includes a connecting sleeve 6 threadedly sleeved on the water testing joint pipe 1 and a connecting box 7 arranged on the connecting sleeve 6, and an installation groove 701 and a yield groove 702 are provided on the connecting box 7, and a clamping member 8 for clamping and limiting the connecting ring 401 is provided on the connecting box 7, and the clamping member 8 includes a trapezoidal block 805 slidably arranged inside the installation groove 701, and a supporting member 9 for supporting and limiting the detection fire pipe 4 is also provided on the connecting box 7, and the supporting member 9 includes an arc-shaped plate 903 that fits the outer side surface of the detection fire pipe 4; specifically, when a water test is required, the connecting sleeve 6 can be first threadedly sleeved on the water testing joint pipe 1, and then the detection fire pipe 4 can be inserted into the through groove. , so that the sealing gasket 403 fits with the sealing groove 101. When it is inserted into the detection fire protection pipe 4, the connecting ring 401 will squeeze the trapezoidal block 805 so that it can be collected into the installation groove 701. After the connecting ring 401 moves to the appropriate position, the squeezing of the trapezoidal block 805 is lost. Under the action of the spring 803, the trapezoidal block 805 can be restored to its original position, thereby limiting the connecting ring 401. After that, when the connecting sleeve 6 is rotated, the connecting box 7 can be driven to move forward, and then the trapezoidal block 805 can be driven to move in the direction of the connecting ring 401. During continuous rotation, the trapezoidal block 805 can continuously apply pressure to the connecting ring 401, so that the connecting ring 401 can be pressed tightly against the water testing joint pipe 1, and then the sealing gasket 403 can be more closely fitted with the sealing groove 101, thereby ensuring its sealing effect. When conducting fire protection water testing, it can avoid leakage and water testing failure.

[0025] like Figure 2 As shown, a pressure gauge 2 and a control valve 3 are provided on the water test joint pipe 1; specifically, the pressure gauge 2 and the control valve 3 have the same structure as the pressure gauge and the control valve in the comparative document (application number: 202321572374.1, application name: A fire hydrant system water test device for fire detection), which is the prior art, so the principle, structure and model are not elaborated here.

[0026] like Figure 2 As shown, a through groove matched with the connecting ring 401 is provided on the connecting box 7 ; specifically, the through groove can facilitate the detection of the fire fighting pipe 4 inserted into the interior of the connecting box 7 .

[0027] like Figure 3As shown, a sealing groove 101 is provided on one side of the water test joint pipe 1, a sealing gasket 403 matched with the sealing groove 101 is provided on one side of the connecting ring 401, and a rotating ring 402 is rotatably provided on one side of the connecting ring 401; specifically, the provided sealing gasket 403 can improve the sealing effect after the connection, and when the rotating connecting sleeve 6 is used to perform a pressure test between the water test joint pipe 1 and the detection fire protection pipe 4, the trapezoidal block 805 is in contact with the surface of the rotating ring 402, so that when rotating, it is possible to avoid large friction between the trapezoidal block 805 and the surface of the connecting ring 401.

[0028] like Figure 3 As shown, a fixing plate 801 is fixedly provided in the installation groove 701, and a sliding rod 802 is slidably provided on the fixing plate 801, and a spring 803 is sleeved on the sliding rod 802, and a trapezoidal block 805 is connected to the sliding rod 802, and the top end of the sliding rod 802 extends to the outside of the installation groove 701, and its end on the outside is connected to a mounting handle 804; specifically, under the action of the spring 803, the trapezoidal block 805 can be located inside the through groove, and when the detection fire tube 4 is installed, the connecting ring 401 squeezes the inclined surface of the trapezoidal block 805, so that the trapezoidal block 805 can be received into the inside of the installation groove 701 to avoid affecting the installation of the detection fire tube 4, and when the detection fire tube 4 needs to be disassembled, pulling the mounting handle 804 can drive the trapezoidal block 805 to be received into the inside of the installation groove 701, thereby canceling the limit on the connecting ring 401, and facilitating the disassembly of the detection fire tube 4.

[0029] like Figure 4 As shown, a connecting rod 901 is slidably provided on the connecting box 7, and a screw rod 902 is also threadedly connected to the connecting box 7. An arc plate 903 is connected to the connecting rod 901 and one end of the screw rod 902, and the arc plate 903 is adapted to the give way groove 702; specifically, after the water test joint pipe 1 and the detection fire protection pipe 4 are connected, rotating the screw rod 902 can drive the two arc plates 903 to approach each other, thereby playing a role of clamping and supporting the detection fire protection pipe 4, thereby preventing it from being skewed, which affects the water test effect.

[0030] In summary: when a water test is required, the connecting sleeve 6 can be first threadedly sleeved on the water test joint pipe 1, and then the detection fire hose 4 can be inserted into the through groove, so that the sealing gasket 403 fits with the sealing groove 101. When it is inserted into the detection fire hose 4, the connecting ring 401 will squeeze the trapezoidal block 805 so that it can be collected into the installation groove 701. After the connecting ring 401 moves to the appropriate position, the squeezing of the trapezoidal block 805 is lost. Under the action of the spring 803, the trapezoidal block 805 can return to its original position, so that it can It plays a role of limiting the connecting ring 401. When the connecting sleeve 6 is rotated afterwards, the connecting box 7 can be driven to move forward, and then the trapezoidal block 805 can be driven to move in the direction of the connecting ring 401. During continuous rotation, the trapezoidal block 805 can continuously apply pressure to the connecting ring 401, so that the connecting ring 401 can be pressed tightly against the water testing joint pipe 1, and then the sealing gasket 403 can be more closely fitted with the sealing groove 101, thereby ensuring the sealing effect. When conducting a fire water test, leakage that causes a water test failure can be avoided.
