Description

Technical Field

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

[0002] In the daily maintenance and inspection of fire protection systems, the water flow and water pressure stability of fire sprinkler pipes are key indicators to ensure their fire extinguishing effectiveness.

[0003] Traditional testing methods often require shutting off the main valve of the fire hydrant system, disassembling the sprinkler head, and then connecting the testing equipment. This process not only temporarily disables the pipeline's fire-fighting capability during testing, posing a safety hazard, but may also disrupt normal fire protection in the surrounding area due to water outages. Furthermore, in older buildings or environments with complex piping systems, water flow can be obstructed due to scale buildup, blockages, or leaks at joints. Existing testing tools are difficult to align quickly and accurately with pipe joints during installation, making the process cumbersome and inefficient. Especially during water jetting, the water sprayed during installation and removal can easily splash and pollute the environment, increasing the workload for testing personnel. Therefore, a fire sprinkler head pipeline testing device is urgently needed to solve these problems. Utility Model Content

The water collection cylinder is equipped with an auxiliary assembly component for quickly aligning and installing the pressure measuring component with the connecting pipe.

[0006] Preferably, the pressure measuring component includes a water pressure gauge disposed inside the water receiving hopper, and a connector is fixedly connected to the top of the water pressure gauge, and the connector is threadedly connected to the connecting pipe.

[0007] Preferably, the auxiliary assembly includes a threaded seat fixedly connected to the inner wall of the bottom of the water collecting cylinder, a threaded rod is threadedly connected to the inside of the threaded seat, a fixing post is fixedly connected to one end of the threaded rod, and the end of the fixing post away from the threaded rod is fixedly connected to the outer wall of the bottom circumference of the water pressure gauge.

[0008] Preferably, a handle is fixedly connected to one end of the threaded rod extending to the outside of the water collecting cylinder, and a handle is fixedly connected to the outer circumferential wall of the water collecting cylinder.

[0009] Preferably, a water baffle is fixedly connected to the outer circumference of the connector, and the water baffle covers the bottom of the water pressure gauge.

[0010] Preferably, the outer circumferential wall of the baffle plate is provided with guide strips that are evenly spaced and distributed in a circular pattern.

[0011] Preferably, a partition is fixedly connected to the inner circumference of the water collecting cylinder, a sealing groove is provided at the bottom of the partition, an installation groove is provided on the outer circumference of the fixing column, a sealing ring is snapped into the installation groove, and the sealing ring is snapped and sealed with the sealing groove.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 In this embodiment of the utility model, a fire sprinkler pipe testing device includes a water receiving hopper 1, a water collecting cylinder 5 fixedly connected to the bottom end of the water receiving hopper 1, the water collecting cylinder 5 being connected to the water receiving hopper 1, and a pressure measuring component for testing the flow of water inside the fire pipe 11 being provided inside the water receiving hopper 1. Both the water receiving hopper 1 and the water collecting cylinder 5 are made of transparent material, which makes it convenient for staff to quickly connect the pressure measuring component to the fire pipe 11. The water collection cylinder 5 is equipped with an auxiliary assembly component for quickly aligning and installing the pressure measuring component with the connecting pipe 12.

[0021] Furthermore, the pressure measuring component includes a water pressure gauge 9 installed inside the water receiving hopper 1. A connector 4 is fixedly connected to the top of the water pressure gauge 9. The connector 4 is threadedly connected to the connecting pipe 12, which facilitates the tight connection between the water pressure gauge 9 and the connecting pipe 12. The water pressure gauge 9 enables effective detection of the water flow pressure inside the fire-fighting pipeline 11.

[0022] Furthermore, the auxiliary assembly components include a threaded seat 19 fixedly connected to the inner wall of the bottom of the water collection cylinder 5. The threaded seat 19 has a threaded rod 8 internally connected to it. One end of the threaded rod 8 is fixedly connected to a fixing post 10. The end of the fixing post 10 away from the threaded rod 8 is fixedly connected to the outer circumference of the bottom of the water pressure gauge 9. The end of the threaded rod 8 extending to the outside of the water collection cylinder 5 is fixedly connected to a handle 7. The outer circumference of the water collection cylinder 5 is fixedly connected to a handle 6. When the fire sprinkler head 13 is removed, the operator quickly presses the connector 4 against the end of the connecting pipe 12 and rotates the handle 7. At this time, the handle 7 can drive the threaded rod 8 to rotate together. When the threaded rod 8 rotates, it can drive the water pressure gauge 9 to rotate and rise together until the water pressure gauge 9 is connected to the connecting pipe 12. At this time, by observing the pressure value on the water pressure gauge 9, it is possible to judge whether the water flow in the fire pipeline 11 is normal. This facilitates the inspection of the fire sprinkler head 13 pipeline. Moreover, the entire inspection process can be carried out without stopping the water supply, which expands the applicability of the device and meets people's usage needs.

[0023] Furthermore, a water baffle 2 is fixedly connected to the outer circumference of the connector 4. The water baffle 2 covers the bottom of the water pressure gauge 9. Covering the bottom of the water pressure gauge 9 can prevent the water flow sprayed from the connecting pipe 12 from directly impacting the water pressure gauge 9, avoiding damage to the dial and internal components of the water pressure gauge 9, and preventing the water flow from interfering with the reading of the water pressure gauge 9, thus ensuring the accuracy of the test data.

[0024] Furthermore, the outer circumference of the baffle plate 2 is provided with equally spaced circular guide strips 3. The guide strips 3 can guide the water flowing into the water receiving hopper 1, so that the water flows more smoothly to the water collecting cylinder 5, reducing the accumulation of water near the baffle plate 2, improving the water collection efficiency, and further preventing water from splashing and polluting the environment.

[0025] Furthermore, a partition 14 is fixedly connected to the inner circumference of the water collecting cylinder 5. A sealing groove 15 is provided at the bottom of the partition 14, and an installation groove 17 is provided on the outer circumference of the fixing column 10. A sealing ring 16 is snapped into the installation groove 17, and the sealing ring 16 and the sealing groove 15 are locked together. The partition 14 divides the internal space of the water collecting cylinder 5, and the sealing groove 15 at its bottom engages with the sealing ring 16 in the installation groove 17 on the fixing column 10, which can effectively prevent the water collected in the water collecting cylinder 5 from flowing through the fixing column 10 and... Leakage occurs in the gap between the partitions 14. The outer circumference of the fixed column 10 is fixedly connected with a limiting plate 18 to prevent the water pressure gauge 9 from falling excessively. When the water pressure gauge 9 falls due to the rotation of the threaded rod 8, the limiting plate 18 on the outer wall of the fixed column 10 can form a block by contacting the bottom of the partition 14, preventing the water pressure gauge 9 from falling excessively and causing it to collide with the bottom of the water collection cylinder 5 or other components and causing damage. At the same time, it prevents the threaded rod 8 from being excessively screwed out of the threaded seat 19 and detached from the assembly, ensuring the stability and safety of the device structure.

[0026] Working principle: The operator holds handle 6 and places the entire device directly below the fire sprinkler head 13. Then, the operator unscrews the fire sprinkler head 13 and disconnects it from the end of the connecting pipe 12. During this process, water from the fire pipe 11 will spray out from the end of the connecting pipe 12. The sprayed water will fall into the water receiving hopper 1 and eventually flow into the water collection cylinder 5 for collection, preventing water from spraying and polluting the indoor environment when the fire sprinkler head 13 is disassembled. After the fire sprinkler head 13 is removed, the operator quickly presses the connector 4 against the end of the connecting pipe 12 and turns the handle 7. The handle 7 will drive the threaded rod 8 to rotate. When the threaded rod 8 rotates, it will drive the water pressure gauge 9 to rotate and rise until the water pressure gauge 9 is connected to the connecting pipe 12. By observing the pressure value on the water pressure gauge 9, the operator can judge whether the water flow in the fire pipe 11 is normal. This facilitates the inspection of the fire sprinkler head 13 pipeline, and the entire inspection process can be carried out without stopping the water supply, expanding the applicability of the device and meeting people's needs.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
