Technical Field

[0001] This application relates to the technical field of fire detection devices, and particularly relates to a water test joint for fire detection. Background Art

At present, during the disassembly process after the water test joint is detected, since there is water inside the water test joint, the water is likely to splash out during disassembly, affecting the operation of the staff. Therefore, a water test joint for fire detection is proposed. Utility Model Content

[0003] In order to solve the problem that there is water inside the water test joint and the water is likely to splash out during disassembly, affecting the operation of the staff, this application provides a water test joint for fire detection.

[0004] The water test joint for fire detection provided by this application adopts the following technical solutions:

[0005] A water test joint for fire detection includes a detection pipeline. One end of the detection pipeline is provided with a connecting plate, and a telescopic sleeve is connected between the detection pipeline and the connecting plate. The connecting plate and the telescopic sleeve make one end of the detection pipeline closed, and a telescopic mechanism is arranged on the surfaces of the connecting plate and the detection pipeline. The telescopic mechanism can move the connecting plate along the axial direction of the detection pipeline, so that the telescopic sleeve extends or contracts.

[0006] Preferably, a pressure gauge is fixedly installed on the surface of the detection pipeline, and the detection probe of the pressure gauge is located inside the detection pipeline.

[0007] Preferably, the telescopic mechanism includes sliding seats fixedly installed on both sides of the detection pipeline. Connecting rods are fixedly connected to both sides of the connecting plate. Cylindrical grooves are respectively formed inside the sliding seats. One end of the connecting rod is fitted and installed inside the cylindrical groove to form a moving pair with it. A spring is sleeved on the surface of the connecting rod. One end of the spring is fixedly connected to the inner surface of the cylindrical groove, and the other end of the spring is fixedly connected to the end of the connecting rod. A threaded sleeve is rotatably connected to the surface of the connecting plate. The threaded sleeve is circular and sleeved on the surface of the telescopic sleeve. A threaded groove adapted to the threaded sleeve is formed in one side opening of the detection pipeline. The threaded sleeve can be screwed into or out of the threaded groove.

[0008] Preferably, when the threaded sleeve is located inside the threaded groove, the spring is in a stretched state.

[0009] Preferably, a flange is fixedly connected to the end of the detection pipeline away from the connecting plate.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] After the system pressure of the fire hydrant is detected by the utility model, the fire hydrant is first closed, and then the threaded sleeve is screwed out of the threaded groove. The stretched spring can be restored, driving the connecting plate and the telescopic sleeve to move, so that the telescopic sleeve extends, and the internal space of the detection pipeline can be expanded to relieve the pressure inside the detection pipeline. Therefore, when the detection pipeline is disassembled, the water flow rate is relatively slow and will not splash everywhere, which is convenient for the staff to operate.

[0016] The following further describes the present application in detail with reference to the attached Figures 1-3 drawings.

[0017] The embodiment of the present application discloses a water test joint for fire detection, including a detection pipeline 1. One end of the detection pipeline 1 is provided with a connecting plate 5. A telescopic sleeve 6 is connected between the detection pipeline 1 and the connecting plate 5. The connecting plate 5 and the telescopic sleeve 6 make one end of the detection pipeline 1 closed, and a telescopic mechanism is arranged on the surface of the connecting plate 5 and the detection pipeline 1. The telescopic mechanism can move the connecting plate 5 along the axial direction of the detection pipeline 1 to make the telescopic sleeve 6 extend or contract.

[0018] Further, a flange 2 is fixedly connected to the end of the detection pipeline 1 away from the connecting plate 5.

[0019] Further, a pressure gauge 3 is fixedly installed on the surface of the detection pipeline 1, and the detection probe of the pressure gauge 3 is located inside the detection pipeline 1.

[0020] Further, the telescopic mechanism includes sliding seats 4 fixedly installed on both sides of the detection pipeline 1. Both sides of the connecting plate 5 are fixedly connected with connecting rods 8. Cylindrical grooves 10 are respectively formed inside the sliding seats 4. One end of the connecting rod 8 is fitted and installed inside the cylindrical groove 10 to form a moving pair therewith. A spring 9 is sleeved on the surface of the connecting rod 8. One end of the spring 9 is fixedly connected with the inner surface of the cylindrical groove 10, and the other end of the spring 9 is fixedly connected with the end of the connecting rod 8. A threaded sleeve 7 is rotatably connected to the surface of the connecting plate 5. The threaded sleeve 7 is circular and sleeved on the surface of the telescopic sleeve 6. A threaded groove 11 adapted to the threaded sleeve 7 is formed at an opening on one side of the detection pipeline 1. The threaded sleeve 7 can be screwed into or out of the threaded groove 11.

[0021] Further, when the threaded sleeve 7 is located inside the threaded groove 11, the spring 9 is in a stretched state.

[0022] In this embodiment, when it is necessary to detect the fire hydrant, one end of the detection pipeline 1 is installed at the outlet end of the fire hydrant by using the flange 2 and bolts, etc. Before detection, it is necessary to screw the threaded sleeve 7 into the threaded groove 11 to make the telescopic sleeve 6 in a contracted state; after the operation is completed, the fire hydrant can be opened, and water is introduced into the detection pipeline 1. According to the reading on the pressure gauge 3, the water pressure value can be obtained, so as to judge the system pressure of the fire hydrant. After the detection is completed, first close the fire hydrant, and then screw the threaded sleeve 7 out of the threaded groove 11. The stretched spring 9 can be restored, driving the connecting plate 5 and the telescopic sleeve 6 to move, so that the telescopic sleeve 6 elongates, and the internal space of the detection pipeline 1 can be enlarged to release the pressure inside the detection pipeline 1. Therefore, when the detection pipeline 1 is disassembled, the water flow rate is relatively slow and will not splash everywhere, which is convenient for the staff to operate.

[0023] It should be noted that: Any existing model can be selected for the pressure gauge 3 for cooperation. Its working principle is mainly based on the elastic deformation generated by the elastic sensitive element under the action of pressure. When these elastic sensitive elements are subjected to external pressure, they will produce corresponding elastic deformations, and this deformation amount is proportional to the magnitude of the applied pressure. Specifically, when the water pressure acts on the sensitive element of the pressure gauge 3, the sensitive element will deform due to the pressure, and this deformation amount is transmitted to the pointer through the conversion mechanism inside the meter, causing the pointer to rotate, so as to indicate the corresponding pressure value on the dial.

[0024] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship.

For other structures, reference can be made to the general design. Without conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;
