Description

Technical Field

[0001] This utility model relates to the field of fire hydrant pressure testing technology, specifically a fire hydrant pressure testing device. Background Technology

[0002] A fire hydrant is a fixed firefighting tool whose main function is to control combustibles, isolate oxidizers, and eliminate ignition sources. Fire hydrants primarily allow fire trucks to draw water from municipal water supply networks or outdoor fire water supply networks for firefighting; they can also be directly connected to hoses and nozzles for firefighting.

[0003] A fire hydrant pressure testing device is a specialized device used to detect the static water pressure and outlet water pressure of indoor and outdoor fire hydrants, and to calibrate the water jet filling of the fire hose. It mainly consists of a fire hose nozzle, a tee, a pressure gauge, and a pressure relief valve. It forms a pressure testing loop at the fire hydrant outlet. When connected to a fire hydrant, opening the pressure relief valve detects the outlet water pressure, and closing the valve detects the static water pressure.

[0004] According to the description in the patent announcement (authorization announcement number: CN218973713U) of a simple fire hydrant pressure testing device, the simple fire hydrant pressure testing device includes "pressure testing tube, connecting frame, pressure gauge" etc., to realize pressure testing.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This simple fire hydrant pressure measuring device uses a pressure measuring tube, connecting frame, pressure gauge, etc. to perform pressure measurement. During use, the device measures pressure using a pressure gauge. However, because the device is an integrated design, it is impossible to install and disassemble the components, which affects the effectiveness of use and the convenience of carrying. Furthermore, it cannot fully measure both static water pressure and outlet water pressure. Therefore, this device needs to be improved. Utility Model Content

[0007] The purpose of this invention is to provide a fire hydrant pressure measuring device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a fire hydrant pressure testing device, comprising a fire hydrant body, a water outlet pipe fixedly connected to the right side of the fire hydrant body, a pressure testing mechanism provided on the right side of the water outlet pipe, and a sealing mechanism provided around the pressure testing mechanism;

[0009] The pressure testing mechanism includes a connector threaded into the inside of the outlet pipe. A rotating disk is fixedly connected to the periphery of the connector, and a sealing seat is fixedly connected to the periphery of the connector. A tee pipe is threadedly connected to the periphery of the connector, and the tee pipe is located on the right side of the sealing seat. A pressure gauge is fixedly connected to the top of the tee pipe. A pressure relief valve is slidably connected to the right side of the tee pipe. A sealing ring is fixedly connected to the left side of the pressure relief valve and slidably connected to the periphery of the right end of the tee pipe. A connecting frame is fixedly connected to the periphery of the tee pipe. An adjusting shaft is threadedly connected inside the connecting frame. A fixed block is rotatably connected to the rear side of the adjusting shaft and inserted into the inside of the pressure relief valve. A movable frame is fixedly connected to the front side of the fixed block and slidably connected to the inner side of the connecting frame.

[0010] Preferably, the left side of the tee pipe is in contact with the right side of the sealing seat, and a sliding groove is provided on the inner side of the connecting frame. The movable frame is slidably connected in the sliding groove, which facilitates the stability of the movable frame when it moves under the action of the sliding groove.

[0011] Preferably, the fixing block passes through the inside of the tee pipe and the sealing ring. The pressure relief valve, the tee pipe and the sealing ring are respectively provided with fixing grooves, and the three fixing grooves correspond to each other. The fixing block is inserted into the fixing groove, which facilitates the stability of the connection between the pressure relief valve and the tee pipe under the action of the fixing block.

[0012] Preferably, the connecting frame, adjusting shaft, fixing block and moving frame are provided in two sets, and the two sets of connecting frame, adjusting shaft, fixing block and moving frame are symmetrically distributed on the front and rear sides of the three-way pipe, so that by setting two sets, the connection between the pressure relief valve and the three-way pipe can be further guaranteed to be stable.

[0013] Preferably, the sealing mechanism includes a first sealing gasket, which is slidably connected to the periphery of the connector and disposed on the right side of the water outlet pipe. A first insert rod is fixedly connected to the right side of the first sealing gasket, and a second sealing gasket is inserted into the bottom of the first sealing gasket.

[0015] Compared with the prior art, this utility model provides a fire hydrant pressure measuring device, which has the following beneficial effects:

[0016] 1. This fire hydrant pressure testing device, through its pressure testing mechanism, allows for pressure testing of the fire hydrant body. First, the rotating disc is rotated to connect the connector threaded into the outlet pipe, connecting it to the fire hydrant body. Simultaneously, a tee pipe is threaded onto the outside of the connector, connecting the tee pipe to the fire hydrant body, stabilizing the pressure gauge. The pressure relief valve is then slidably connected to the right side of the tee pipe, with the sealing ring slidably connected to the outer edge of the right end of the tee pipe. Rotating the adjusting shaft causes the fixing block to insert into the sealing ring, pressure relief valve, and tee pipe, stabilizing the three components. This facilitates easy installation and disassembly of the pressure relief valve. A pressure gauge is mounted on the top of the tee pipe, allowing for real-time and intuitive measurement of the water pressure inside the fire hydrant. Closing the pressure relief valve and recording the pressure gauge reading is the static water pressure of the fire hydrant. Opening the fire hydrant valve and activating the pressure relief valve simulates the water flow from a fire hose; the pressure gauge reading at this point is the outlet pressure.

[0017] 2. This fire hydrant pressure testing device, through its sealing mechanism, allows the first and second sealing gaskets to slide and connect to the periphery of the connector when the connector is connected to the outlet pipe, and they are in an interlocking state. At the same time, the first and second sealing gaskets are in close contact with the right side of the outlet pipe, and the first and second insert rods are inserted into the connector, further enhancing the sealing effect, preventing water leakage during pressure testing, and improving the overall sealing performance of the device.
