Description

Technical Field

[0001] The invention relates to the technical field of sprinkler head pressure testing equipment, and in particular to a sprinkler head pressure testing equipment and a use method thereof. Background Art

[0002] The sprinkler head is an important fire extinguishing component in the automatic sprinkler fire extinguishing system that directly detects and senses fire. It can control the spread of fire in time and ensure the safety of life and property. When inspecting the sprinkler head, the manufacturer needs to conduct a water pressure test on the sprinkler head. The sprinkler head includes a threaded pipe for installation, a spraying structure, and a connecting block for connecting the threaded pipe and the spraying structure. When testing the sprinkler head, the pipeline needs to go through the processes of boosting, maintaining pressure, reducing pressure, boosting, and reducing pressure.

[0003] In the prior art, most sprinkler head pressure testing equipment performs water pressure tests on several sprinkler heads at the same time. When multiple sprinkler heads spray water, the water pressure in the pipeline will drop, causing the rear sprinkler heads to fail to reach the desired water pressure when testing the water pressure. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a sprinkler head pressure testing device and a method of using the same to solve the above problems.

[0005] In view of this, the present invention provides a sprinkler nozzle pressure testing device, comprising: The chassis includes a support base disposed on the ground and a mounting frame disposed on the top of the support base; A water supply device is installed on the ground; A pressure stabilizing device is arranged on the ground, and the input end of the pressure stabilizing tank is connected to the output end of the water supply device; A plurality of water pipes, one end of which is connected to the output end of the voltage stabilizing device, the middle part of which is installed in the mounting frame, and the other end of which passes through the mounting frame and is connected to the output end of the water supply device; A number of pressure measuring devices are respectively arranged on the water delivery pipeline; A plurality of connecting pipes, one end of which is disposed on the water pipe at intervals and connected to the water pipe, and the other end of which penetrates the mounting frame and is located outside the mounting frame; A plurality of solenoid valves are respectively installed in openings at one end of a plurality of connecting pipes connected to the water delivery pipe; A plurality of clamping devices are respectively arranged in openings at one end of a plurality of connecting pipes away from the mounting frame; and a control device, which is arranged on the ground and is electrically connected to the pressure measuring device, the solenoid valve, the pressure stabilizing device and the water supply device respectively; The clamping device is used to clamp the nozzle, and an opening and closing member is provided at one end of the water pipe close to the water supply device.

[0006] By adopting the above technical solution, firstly, several nozzles that need to be tested are installed on the clamping device, so that several nozzles can be tested later, and then the control device controls the water supply device to open, and the water supply device supplies water to several pressure stabilizing devices. At the same time, the control device controls the opening and closing parts to close, and then the control device controls several pressure stabilizing devices to slowly open to discharge water to several water pipes. The pressure measuring device sends the water pressure data in the water pipes to the control device. When the value is reached, the control device controls the pressure stabilizing device to stop opening. Through the control of the water pressure, the nozzle can work under the water pressure that needs to be tested, so as to see whether the nozzle meets the requirements. Finally, the control device controls the output A solenoid valve closest to the pressure stabilizing device in the water pipe is opened, and water first enters the connecting pipe and then into the nozzle. At this time, the water pressure test is performed on the first nozzle. When the second nozzle needs to be tested, the first opened solenoid valve is closed, and then the second solenoid valve is opened. Similarly, until the last nozzle is tested. When it is necessary to test the nozzle conditions at different water pressures, the control device controls the pressure stabilizing device to change the output, so as to achieve different water pressures in the water pipe. Then, the above-mentioned test nozzles are tested one by one. By setting the test nozzles one by one, it is possible to prevent the water pressure in the water pipe from dropping when the number of nozzles opened increases, thereby causing the test pressure of the subsequent nozzles to fall short of the test value.

[0007] In the above technical solution, the clamping device further comprises: The installation groove is arranged at the opening of one end of the connecting pipe away from the water pipe; A sealing mechanism is installed in the installation groove; and a clamping mechanism, which is installed at the end of the connecting pipe away from the water pipe; The sealing mechanism is used to seal the threaded tube of the nozzle and the mounting groove, and the clamping mechanism is used to clamp the connection block of the nozzle.

[0008] In the present technical solution, the sealing mechanism can be installed by setting the mounting groove, and the sealing mechanism can form a seal between the threaded tube of the nozzle and the mounting groove, thereby preventing water from flowing out between the threaded tube and the wall of the mounting groove, and the nozzle can be fixed by setting the clamping mechanism.

[0009] In the above technical solution, the sealing mechanism further comprises: A sliding ring groove is arranged on the inner wall of the mounting groove; The movable ring has an outer wall which is in contact with the inner wall of the sliding ring groove and slides in the sliding ring groove; A first elastic member, one end of which is connected to a side wall of the sliding ring groove close to the opening of the connecting pipe, and the other end of which is connected to the moving ring; The sealing block is in the shape of a hollow cylinder, the outer wall of the sealing block is attached to the inner wall of the installation groove and connected to the inner wall of the movable ring, and an insertion groove for inserting the nozzle threaded pipe is provided on one end of the sealing block away from the bottom of the installation groove; and a sealing assembly, wherein the fixed end is arranged at the bottom of the installation groove, and the sealing end extends to the inner wall of the sealing block facing one end of the installation groove; Among them, an insertion groove for inserting the nozzle threaded tube is provided on the end of the sealing block away from the bottom of the mounting groove, and in the initial state, the first elastic member supports the movable ring to be located in the middle of the sliding ring groove, so that one end of the sealing block is inserted into the mounting groove and the other end is located outside the connecting tube, and the port of the sealing block inserted into one end of the mounting groove is located on the side of the movable ring facing the bottom of the mounting groove, and when the movable ring is pushed to the side of the sliding ring groove close to the bottom of the mounting groove, a seal is generated between the sealing end of the sealing assembly and the sealing block, and at this time, the clamping mechanism can just clamp and fix the connecting block of the nozzle.

[0010] In the present technical scheme, when the nozzle needs to be installed, the threaded tube of the nozzle is first inserted into the insertion groove, and then the nozzle is pushed to move toward the installation groove. At this time, the first elastic member is stretched, and the moving ring slides in the sliding ring groove and moves toward the side wall of the sliding ring groove. When the moving ring moves to fit the side wall of the sliding ring groove, a seal is formed between the threaded tube of the nozzle and the sealing assembly. The port of the sealing block plugged into one end of the installation groove is located on the side of the moving ring facing the bottom of the installation groove, so that the sealing assembly and the sealing block can be better matched, thereby preventing water from passing between the threaded tube of the nozzle and the inner wall of the installation groove when testing the nozzle. When the threaded tube of the nozzle is fully inserted, the clamping mechanism just fixes the connecting block of the nozzle, so that the nozzle is installed and fixed as a whole. Through the above-mentioned cooperation, the nozzle can be quickly installed, and the threaded connection of the threaded tube of the nozzle does not need to be connected for installation. First, when measuring the water pressure, the maximum pressure measurement value will appear, and the nozzle is subjected to a large force, which causes the threaded tube of the nozzle to be easily lost.

[0012] In the present technical solution, through the setting of the second elastic member, the frustum can be stretched when being impacted by water. When the frustum is impacted by the water flow, it is squeezed on the inner wall of the sealing block, so that the outer wall of the sealing block is in contact with the inner wall of the mounting groove to produce a seal.
