Description

Technical Field

[0001] This utility model relates to the technical field of fire protection facilities, and in particular to a pressure testing device for sprinkler networks. Background Technology

[0002] Sprinkler systems are important fire protection facilities. Their piping networks must undergo rigorous water pressure strength tests and air tightness tests after installation or during regular maintenance to ensure that their pressure resistance and sealing performance meet the specifications.

[0003] Existing sprinkler network pressure testing devices, such as the portable fire-fighting network pressure testing tool disclosed in utility model patent application number 202323537669.8, mainly include a connecting assembly. The pressure gauge is installed above the short pipe body, and two fixing plates are fixed to the bottom of the short pipe body. Connecting clamps one and two are rotatably mounted on the front and rear sides of the two fixing plates, and connecting clamps one and two are symmetrically distributed. Connecting clamp two is provided on the side of connecting clamp one that is close to connecting clamp one. In use, after the fastener passes through the two protruding plates, it returns to its original position so that the top side of the fastener abuts against one side of the protruding plate. When one side of the fastener is in contact with the protruding plate, the spring is compressed to its shortest state. When the liquid flows along the short pipe body, the pressure of the liquid inside the short pipe body is detected by the pressure gauge.

[0004] However, most existing pressure testing devices require pipe clamps to connect the device to the spray pipe network, which is very troublesome and makes it difficult to guarantee the sealing effect of the connection. Moreover, the devices are not very intelligent, manual readings are prone to errors, and they do not have the function of recording. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a spray pipe network pressure testing device that not only improves the connection speed between the device and the spray pipe, eliminates the trouble of tightening bolts, and ensures the sealing effect of the connection, but also allows for accurate reading and recording of test data, thus improving the intelligence level of the device.

[0006] This utility model discloses a spray pipe network pressure testing device, including a positioning mechanism; it also includes four sets of fixing mechanisms, a connecting mechanism, a pressure relief mechanism, and a detection mechanism. The four fixing mechanisms are all installed on the positioning mechanism to fix the pipe; the connecting mechanism is installed on the positioning mechanism to enhance the sealing of the connection with the pipe; the pressure relief mechanism is installed on the connecting mechanism to facilitate pressure relief; and the detection mechanism is installed on the pressure relief mechanism to facilitate reading and recording. The operator inserts the end pipe of the spray pipe network into the connecting mechanism, activates the four fixing mechanisms to fix the pipe, then activates the connecting mechanism to enhance the sealing effect of the connection; the detection mechanism detects and records the pressure inside the pipe; after the test is completed, the pressure relief mechanism is opened to release pressure, making it easy to disassemble the device.

[0007] Preferably, the positioning mechanism includes a protective box, six sets of support legs, wear-resistant rings, and a handle. The protective box has an internal cavity, the tops of the six sets of support legs are connected to the bottom of the protective box, and the protective box has through holes. The wear-resistant rings are installed in the through holes of the support legs, and the bottom of the handle is connected to the top of the protective box. The six sets of support legs provide convenient support for the protective box when not in use, maintaining its stability. When needed, the operator operates the handle to lift the protective box, allowing the end pipe of the sprinkler network to be inserted into the through hole. The wear-resistant rings prevent friction between the pipe and the protective box.

[0008] Preferably, the fixing mechanism includes two sets of first hydraulic cylinders, a fixing plate, and multiple sets of racks. The two sets of first hydraulic cylinders are installed inside the cavity of the protective box, the fixing plate is installed on the top of the two sets of first hydraulic cylinders and connected, and the multiple sets of racks are installed on the fixing plate. The four pressure relief mechanisms are evenly distributed inside the cavity of the protective box, and each set of first hydraulic cylinders is equipped with a synchronization valve. The detection mechanism controls the multiple sets of first hydraulic cylinders to start synchronously through the synchronization valve. The four sets of fixing plates are pressed against the outside of the end pipe to fix and clamp it. By setting multiple sets of racks, the friction between the pipe and the fixing effect is increased, thus enhancing the fixing effect.

[0009] Preferably, the connecting mechanism includes four sets of guide columns, four sets of second hydraulic cylinders, a connecting plate, a connector, and a sealing ring. All four sets of guide columns are mounted on the protective box, and all four sets of second hydraulic cylinders are mounted on the protective box. The connecting plate is slidably mounted on the four sets of guide columns and connected to the top of the four sets of second hydraulic cylinders. The connector and the sealing ring are mounted on the connecting plate. The end pipe of the spray network is inserted into the connector, and the sealing ring seals the connection. After the fixing mechanism secures the pipe, the four sets of second hydraulic cylinders are activated to continuously pull the connecting plate, ensuring the connector is tightly fitted to the end pipe and guaranteeing a sealing effect. The stability of the connecting plate's movement is ensured by the four sets of guide columns.

[0010] Preferably, the sealing ring surface is covered with a conductive fiber patch; the conductive fiber patch conducts electricity when it comes into contact with water, triggering an alarm, and the alarm signal is transmitted to the testing agency to remind the staff to test the sealing performance of the device.

[0011] Preferably, the pressure relief mechanism includes a detection pipe, a drain pipe, and a pressure relief valve. The detection pipe is internally connected to the insertion pipe, and the drain pipe is internally connected to the detection pipe. The pressure relief valve is installed on the drain pipe. The detection mechanism detects the pressure inside the detection pipe. After the detection is completed, the operator opens the pressure relief valve to allow water to drain through the drain pipe, thus releasing the pressure in the end pipe and facilitating the removal of the device.

[0012] Preferably, the testing mechanism includes a pressure gauge, a control box, a display screen, and connecting cables. The pressure gauge is installed on the testing tube, the control box is installed on the protective box, the display screen is installed on the control box, and the connecting cables are installed between the control box and the pressure gauge. The pressure gauge detects the pressure inside the testing tube, and the test results are transmitted to the control box for processing via the connecting cables. The display screen shows the test pressure, and at the same time, the operator controls the extension and retraction of the first and second hydraulic cylinders via the display screen and the connecting cables.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff inserts the end pipe of the sprinkler network into the connection mechanism, activates the four sets of fixing mechanisms to fix the pipe, then activates the connection mechanism to enhance the sealing effect of the connection, the detection mechanism detects and records the pressure in the pipe, and after the test is completed, the pressure relief mechanism is opened to release the pressure, making it convenient to remove the device.
