Technical Field
[0001] This utility model relates to the field of fire protection terminal monitoring connector technology, and in particular to a fire protection terminal pressure and flow monitoring connector device. Background Technology
[0002] A fire-fighting terminal pressure and flow monitoring connector is a specialized testing device used only at the very end (i.e., the most unfavorable point) of a fire-fighting system's piping network. It mainly consists of a test valve, pressure gauge, test connector (or sprinkler head), and corresponding connecting fittings. It is an indispensable "diagnostic tool" in sprinkler systems. Through regular testing, it ensures that the entire system can reliably activate, alarm, and effectively extinguish fires in the event of a fire, making it a crucial link in protecting life and property.
[0003] Traditional fire-fighting terminal pressure and flow monitoring connectors typically use steel pipes to connect various measuring components in series. In practical applications, the ends of the steel pipes need to be threaded and wrapped with PTFE tape and hemp rope, making the installation process cumbersome and inconvenient. Therefore, this paper proposes an improved fire-fighting terminal pressure and flow monitoring connector device. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fire-fighting terminal pressure and flow monitoring connector device, which effectively solves the deficiencies of the prior art.
[0005] To achieve the above objectives, one embodiment of the present invention provides a fire-fighting terminal pressure and flow monitoring connector device, including a mounting housing with open ends, and a water flow indicator and a control valve are sequentially mounted on one end of the mounting housing; An impeller hole is provided on one side of the mounting housing, a meter is mounted on the side of the mounting housing, an impeller is mounted on the end of the meter, and the impeller enters the interior of the mounting housing through the impeller hole; A vertically downward-facing nozzle is installed at the end of the mounting housing away from the water flow indicator, and a pressure gauge is installed on the side of the mounting housing near the bottom of the water flow indicator. A mounting bracket is installed on the other side of the mounting housing. A connecting bracket is installed at the bottom of the mounting bracket. A fixing ring is installed at the middle and bottom of one side of the connecting bracket. A transparent cover is installed between the two fixing rings. The transparent cover covers the outside of the nozzle. A drainage pipe is installed at the bottom of the transparent cover.
[0006] Preferably, in any of the above solutions, the water flow indicator adopts an acrylic structure in the middle. The two ends of the water flow indicator are fixedly connected to the control valve and one end of the mounting housing respectively by flange bolts, and a sealing gasket is provided between adjacent ends. This solution facilitates the observation of water flow conditions. When the sprinkler head at the end of the pipeline releases water, the water flow pushes the paddle or diaphragm in the water flow indicator to deflect, triggering a micro switch and outputting an electrical signal to the fire control center to realize a fire alarm. This provides a trigger signal for the fire pump and works with the pressure switch in the fire protection system to control the fire pump to start.
[0007] Preferably, in any of the above solutions, the meter is a remote-reading smart water meter, and a sealing gasket is provided between the meter and the mounting housing. In this solution, the meter (IES-WF) includes mechanical components, electrical signal conversion components, and signal transmission components. When water flows through the inside of the mounting housing, it drives the impeller to rotate. Through the cooperation of the mechanical components and the electrical signal conversion components, the mechanical rotation is converted into an electrical signal, and the data is uploaded through the signal transmission components to complete the detection of water flow at the fire-fighting terminal.
[0008] Preferably, in any of the above solutions, the size of the upper fixing ring is larger than that of the lower fixing ring, and multiple limiting blocks are installed at the edge of the top of the transparent cover. The bottom surfaces of the multiple limiting blocks are in contact with the top surface of the upper fixing ring. By using this solution, the transparent cover can be stably installed inside the two fixing rings, and the transparent cover can be stably covered on the outer wall of the nozzle, with a safe distance between it and the outer wall of the nozzle to facilitate air flow. At the same time, the transparent cover can effectively block and collect water flow, and facilitate its outward discharge through the drainage pipe.
[0009] Preferably, in any of the above solutions, a gap is left between the inner wall of the transparent cover and the outer wall of the nozzle. Both the transparent cover and the drain pipe are made of acrylic. This solution allows operators to directly observe the water flow and, in conjunction with a pressure gauge, directly observe the pressure at the fire-fighting terminal.
[0010] This utility model has the following advantages: 1. This fire-fighting terminal pressure and flow monitoring connector device, by setting up an installation housing, adopts a single structure with openings at both ends and sides, thereby providing installation positions for water flow indicators, meters, sprinklers and pressure gauges respectively. Compared with the traditional structure that uses steel pipes for series connection, the above structure is compact, the installation steps are convenient, and it is easy to fix to the external building through the mounting bracket and connecting bracket. It is convenient for operators to install the whole, the overall structure is simple, the design is reasonable, and it is easy to promote and use.
[0011] 2. This fire-fighting terminal pressure and flow monitoring connector device, by setting a connecting frame, has fixing rings installed at the middle and bottom, which facilitates the installation position of the transparent cover. The transparent cover covers the outer wall of the sprinkler head. When the control valve is opened, the water flow enters the sprinkler head along the water flow indicator and the mounting housing and is sprayed out. The transparent cover blocks the sprayed water flow and allows the operator to check the water flow status in time. At the same time, it guides the water flow and leads it to the outside through the diversion pipe to complete the test of the fire-fighting terminal pressure. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0015] like Figures 1 to 7 As shown, a fire-fighting terminal pressure and flow monitoring connector device includes a mounting housing 1, which has an open design at both ends. A water flow indicator 9 and a control valve 8 are sequentially installed at one end of the mounting housing 1. The mounting housing 1 is made of stainless steel or copper, which has good corrosion resistance and meets the usage requirements of the fire-fighting system. An impeller hole 13 is provided on one side of the mounting housing 1. A meter 2 is mounted on the side of the mounting housing 1. An impeller 14 is mounted on the end of the meter 2. The impeller 14 enters the interior of the mounting housing 1 through the impeller hole 13. A vertically downward-facing nozzle 3 is installed at the end of the mounting housing 1 away from the water flow indicator 9. A pressure gauge 7 is installed on the side of the mounting housing 1 near the bottom of the water flow indicator 9. The pressure gauge 7 is a remote pressure gauge (TP2401), which includes a mechanical transmission component, an electrical signal conversion component, and a signal transmission component, used to convert the pressure into an electrical signal for transmission and to detect the water pressure at the fire-fighting terminal. A mounting bracket 10 is installed on the other side of the mounting housing 1. A connecting bracket 6 is installed at the bottom of the mounting bracket 10. A fixing ring 5 is installed in the middle and at the bottom of one side of the connecting bracket 6. A transparent cover 11 is installed between the two fixing rings 5. The transparent cover 11 covers the outside of the nozzle 3. A drainage pipe 12 is installed at the bottom of the transparent cover 11.
[0016] The water flow indicator 9 has an acrylic structure in the middle. The two ends of the water flow indicator 9 are fixedly connected to the control valve 8 and one end of the mounting housing 1 respectively by flange bolts. Sealing gaskets are provided between adjacent ends. As an optional technical solution of this utility model, this facilitates the observation of water flow conditions. When the sprinkler head 3 at the end of the pipeline releases water, the water flow pushes the paddle or diaphragm in the water flow indicator 9 to deflect, triggering the micro switch and outputting an electrical signal to the fire control center to realize fire alarm. It is used to provide a trigger signal for the fire pump and, together with the pressure switch in the fire protection system, controls the fire pump to start.
[0017] Meter 2 is a remote-reading smart water meter. A sealing gasket is provided between meter 2 and mounting housing 1. As an optional technical solution of this utility model, meter 2 (IES-WF300) includes mechanical components, electrical signal conversion components and signal transmission components. When water flows through the inside of mounting housing 1, it drives impeller 14 to rotate. Through the cooperation of mechanical components and electrical signal conversion components, the mechanical rotation is converted into an electrical signal, and the data is uploaded through the signal transmission component to complete the detection of water flow at the fire terminal.
[0018] The upper fixing ring 5 is larger than the lower fixing ring 5. Multiple limiting blocks 4 are installed at the top edge of the transparent cover 11. The bottom surface of the multiple limiting blocks 4 is in contact with the top surface of the upper fixing ring 5. As an optional technical solution of this utility model, this makes it easy for the transparent cover 11 to be stably installed inside the two fixing rings 5, and to stably cover the outer wall of the nozzle 3, leaving a safe distance between the transparent cover 11 and the outer wall of the nozzle 3 to facilitate the flow of air. At the same time, the transparent cover 11 is convenient for blocking and collecting water flow, and convenient for leading it to the outside through the drainage pipe 12.
[0019] A gap is left between the inner wall of the transparent cover 11 and the outer wall of the nozzle 3. Both the transparent cover 11 and the drain pipe 12 are made of acrylic. As an optional technical solution of this utility model, this makes it easier for operators to observe the water flow directly and to observe the pressure at the fire terminal with the pressure gauge 7.
[0020] The following steps are required when using this fire-fighting terminal pressure and flow monitoring connector device: 1) During installation, install the water flow indicator 9, meter 2, sprinkler head 3 and pressure gauge 7 at the opening positions on the outer wall of the mounting housing 1 respectively, and connect one end of the control valve 8 to the external fire pipeline; 2) Open the control valve 8, and the water flows along the water flow indicator 9 into the interior of the mounting housing 1, filling the interior of the mounting housing 1 and spraying out from the nozzle 3; 3) The water flow drives the impeller 14 on the meter 2 to rotate, the gear set inside the meter 2 rotates, the sensor senses the rotation and converts it into a digital signal for transmission, and measures the water flow rate. 4) The water pressure inside the mounting housing 1 acts directly on the pressure gauge 7. The pressure gauge 7, through the cooperation of its internal mechanical structure and sensor, converts the pressure into an electrical signal for transmission, thereby measuring the pressure inside the mounting housing 1. 5) The transparent cover 11 is convenient for blocking the water flow sprayed from the nozzle 3 and collecting the water flow, which is then led out through the drain pipe 12.
[0021] In summary, when in use, the user uses the mounting housing 1, which is a single-unit structure with openings at both ends and sides, to provide installation positions for the water flow indicator 9, meter 2, sprinkler head 3, and pressure gauge 7. Compared to the traditional structure that uses steel pipes for series connection, the above structure is compact, the installation steps are convenient, and it is easy to fix to the external building through the mounting bracket 10 and connecting bracket 6, making it convenient for operators to install the whole. The overall structure is simple, the design is reasonable, and it is easy to promote and use. Furthermore, by setting up the connecting bracket 6, which has fixing rings 5 installed in the middle and bottom, it is easy to provide an installation position for the transparent cover 11. The transparent cover 11 covers the outer wall of the sprinkler head 3. When the control valve 8 is opened, the water flows along the water flow indicator 9 and the mounting housing 1 into the sprinkler head 3 and sprays out. The transparent cover 11 blocks the sprayed water flow and allows the operator to check the water flow status in time. At the same time, it guides the water flow and leads it out to the outside through the diversion pipe 12 to complete the test of the fire terminal pressure.
