Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrant pressure measurement, in particular to a fire hydrant pressure measurement connector. Background Art

[0002] Fire hydrant pressure measuring connectors usually consist of two parts: one is a threaded interface connected to the fire hydrant, and the other is an interface connected to a pressure gauge or manometer. This connector is usually made of metals such as copper or aluminum, and has the characteristics of high strength and corrosion resistance. The function of the fire hydrant pressure measuring connector is to transfer the water pressure of the fire hydrant to the pressure gauge or manometer in order to monitor the pressure of the fire protection system. In the event of a fire or other emergency, the pressure can be monitored to ensure the normal operation of the fire protection equipment and the safety of personnel and property. Fire hydrant pressure measuring connectors usually have standard threaded interfaces that can be connected to various fire hydrants and pressure gauges, which is convenient for use and installation. In daily maintenance and overhaul, fire hydrant pressure measuring connectors can also help staff to promptly discover and solve the pressure problems of fire protection equipment and ensure the normal use of the equipment.

[0003] A fire hydrant pressure measuring connector is disclosed in the Chinese utility model patent application disclosure CN210331479U. Although the utility model can detect the water pressure data at different positions on the pipe body and compare them, so as to more accurately read the water pressure of the fire hydrant, if the seal at the connection is not good enough during use, water seepage will occur. The existing connector cannot detect water leakage at the connection, and has the disadvantage of poor practicality. Utility Model Content

[0013] The utility model provides a fire hydrant pressure measuring connector, which has the following beneficial effects:

[0014] 1. A fire hydrant pressure measuring connector, by fixing a round block, a shield, a capacitive sensor, a data acquisition device and a wireless alarm, enables the fire hydrant pressure measuring connector to have the effect of water seepage detection. When in use, when connecting, first move the pressure measuring tube to the pressure measuring end of the fire pipe, then use raw tape to wrap around the surface of the threaded connector, the pressure measuring end of the fire pipe enters into the shield through the round hole, and the threaded connector is threaded onto the internal thread. After tightening, the sealing ring is squeezed to play a sealing role. After the pressure measuring tube is connected to the fire pipe, the shield is rotated at this time, and the special-shaped ring slider on the inner side of the shield slides in the special-shaped ring groove. The shield is rotated to move the capacitive sensor installed on the inner surface of the shield to the lowest position. At this time, the capacitive sensor is located directly below the connection between the pressure measuring tube and the fire pipe, and then the two locking bolts are tightened. The special-shaped ring slider is tightened and fixed in the special-shaped ring slide groove through the inner end of the locking bolt, which plays a role in limiting the baffle cover. During the use of the connector, if water seepage and leakage occur, water flows to the bottom of the connection between the pressure measuring tube and the fire-fighting pipe and drips downward, and the water drops fall on the surface of the capacitive sensor. When the water drops fall on the capacitive sensor, the dielectric constant of the water will change the capacitance value of the capacitive sensor. This change is monitored and recorded by the data acquisition equipment. The data acquisition equipment analyzes these data to obtain the frequency, time interval and other information of the water droplets, so as to judge the situation of the water droplets falling. The obtained situation information is then sent to the relevant monitoring center by the wireless alarm, which plays the role of automatic water seepage alarm. The device achieves the purpose of improving the practicality of the connector by increasing the monitoring of water seepage and leakage and the automatic alarm after water seepage.
