Description

Technical Field

[0001] This utility model relates to the field of water flow indicators, and in particular to a water flow indicator device for fire pipelines. Background Technology

[0002] Water flow indicators belong to the sight glass category of instrument valves and are suitable for use in industrial production pipelines in petroleum, chemical, chemical fiber, pharmaceutical, food, power plants, pumps, and other industries. Through the sight glass, they allow for real-time observation of the turbidity of liquids, gases, steam, and other media, as well as measurement of the media's flow velocity and reaction status. They are an indispensable pipeline accessory for ensuring normal production and product quality. Connection methods include threaded, flanged, and welded types. Water flow indicators can also be used in automatic sprinkler systems. They can be installed on the main water supply pipe or crossbar water pipes, providing an electrical signal indicating water flow in a specific area. This signal can be sent to the electrical control box, but it is typically not used as a control switch to start the fire pump.

[0003] A water flow indicator disclosed in announcement number CN218294684U includes an indicator body with water injection pipes at both ends. A diversion pipe is fixedly connected to the bottom of the water injection pipe. A sealing device is provided between the two ends of the indicator body and the water injection pipes. A support device is provided between the water injection pipes and the diversion pipes. The sealing device includes six L-shaped brackets and two sealing blocks. One end of the L-shaped bracket is fixedly connected to the outer surface of the indicator body, and the other end of the L-shaped bracket is fixedly connected to a support. Several threaded rods are threadedly connected to the outer surface of the support. A limit block is fixedly connected to one end of the threaded rod. An arc-shaped block is rotatably connected to one side of the limit block. The sealing block is disposed between the outer surfaces of the two ends of the indicator body and the arc-shaped block.

[0004] Based on the above technical features, the problem is that the existing technology requires manual tightening of the threaded rod of the sealing device to seal the gap at the connection with the water supply pipe, which is complicated and has low installation efficiency.

[0005] Therefore, it is necessary to solve the above problems by using a fire pipeline water flow indicator device. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1 to 4 The fire-fighting pipeline water flow indicator shown includes a water flow indicator body 1 installed on the fire-fighting pipeline water supply pipe 2. The water flow indicator body 1 is flanged to the water supply pipe 2. A sealing ring 3 is fitted at the connection between the water flow indicator body 1 and the water supply pipe 2.

[0021] A retaining ring 4 is fitted onto the pipe of the water flow indicator body 1, and the retaining ring 4 is fixedly connected to the pipe of the water flow indicator body 1. Several pressure members for pressing sealing rings 3 are installed on the retaining ring 4. The pressure members are evenly distributed along the circumference of the pipe of the water flow indicator body 1.

[0022] Specifically, the pressing component includes an arc-shaped pressure plate 10 that compresses the sealing ring 3. A guide groove 7 is radially formed inside the fixing ring 4, and the opening of the guide groove 7 is axially formed along the fixing ring 4. A drive shaft 8 passes through the guide groove 7, and the drive shaft 8 is parallel to the central axis of the fixing ring 4. The drive shaft 8 and the guide groove 7 are in a limiting sliding fit. A drive plate 9 is fixedly mounted on the shaft body of the drive shaft 8 that extends out of the guide groove 7, and the arc-shaped pressure plate 10 is hinged to the drive plate 9.

[0023] To ensure that the arc of the arc-shaped pressure plate 10 faces the pipe radially along the water flow indicator body 1, a torsion spring can be installed at the rotational connection between the arc-shaped pressure plate 10 and the transmission plate 9. The rotation axis of the arc-shaped pressure plate 10 passes through the torsion spring, one end of the torsion spring is fixedly connected to the arc-shaped pressure plate 10, and the other end is fixedly connected to the transmission plate 9.

[0024] A rotating ring 5 is rotatably mounted on the pipe of the main body 1 of the water flow indicator. In this embodiment, a fixed ring 4 is mounted on the rotating ring 5, and the rotating ring 5 and the fixed ring 4 are rotatably connected.

[0025] Each transmission plate 9 is connected to the rotating ring 5 via a disassembly assembly, which drives the transmission plate 9 to rotate around the connecting shaft 6.

[0026] Specifically, the assembly / disassembly component includes a connecting shaft 6, which is parallel to the transmission shaft 8 and fixed to the axial end of the rotating ring 5. The transmission plate 9 is rotatably connected to the connecting shaft 6.

[0027] A push plate 12 is fixedly mounted on the rotating ring 5. A relief groove is formed circumferentially inside the fixed ring 4, and the opening of the relief groove faces the rotating ring 5 radially along the fixed ring 4. The push plate 12 is located inside the relief groove and is in a limiting sliding fit with the relief groove.

[0028] A spring 13 is installed in the groove along the rotation direction of the rotating ring 5. One end of the spring 13 is fixedly connected to the push plate 12, and the other end of the spring 13 is fixedly connected to the fixing ring 4.

[0029] A push rod 11 is fixedly mounted radially on the rotating ring 5, and a through groove is formed circumferentially inside the fixed ring 4. The through groove passes through the fixed ring 4 radially. The push rod 11 passes through the through groove and slides with the through groove, which is used for the common displacement of the push rod 11.

[0030] Working principle: When this water flow indicator is installed on the water supply pipe 2 of the fire protection pipeline, the sealing ring 3 is fitted onto the pipe of the water flow indicator body 1. Then, the pipe of the water flow indicator body 1 is connected to the flange of the water supply pipe 2.

[0031] Before connection, push rod 11 is pushed counterclockwise, causing rotating ring 5 to rotate counterclockwise. As rotating ring 5 rotates counterclockwise, it causes connecting shaft 6 to revolve around the central axis of fixed ring 4. Connecting shaft 6 pushes transmission plate 9 to rotate around transmission shaft 8, simultaneously pushing transmission plate 9 radially away from the pipe of water flow indicator body 1 along fixed ring 4. Transmission plate 9 drives arc-shaped pressure plate 10 to move synchronously and move arc-shaped pressure plate 10 away from the pipe of water flow indicator body 1. During this process, rotating ring 5 causes push plate 12 to stretch corresponding spring 13.

[0032] After the drive shaft 8 slides to the end of the guide groove 7 away from the rotating ring 5, the rotating ring 5 stops rotating. At this time, the thrust on the push rod 11 is maintained until the connection is completed.

[0033] After connection, the sealing ring 3 is fitted onto the flange connection. Then, the push rod 11 is released. At this time, the spring 13 contracts. Under the action of the spring 13, the push plate 12 drives the rotating ring 5 to rotate clockwise. The rotating ring 5 drives the connecting shaft 6 to revolve around the central axis of the fixed ring 4. The connecting shaft 6 pushes the transmission plate 9 to rotate around the transmission shaft 8, and simultaneously pushes the transmission plate 9 radially towards the pipe of the water flow indicator body 1 along the fixed ring 4. The transmission plate 9 drives the arc-shaped pressure plate 10 to move synchronously and move the arc-shaped pressure plate 10 towards the pipe of the water flow indicator body 1. During this process, all the arc-shaped pressure plates 10 eventually contact and compress the sealing ring 3, thereby sealing the gap.

[0034] To remove the water flow indicator, push the push rod 11 counterclockwise again. Finally, disconnect the flange connection and remove the sealing ring 3.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
