Description

Technical Field

[0001] This utility model belongs to the technical field of door and window testing equipment, specifically relating to a water spray device for door and window testing. Background Technology

[0002] Existing methods for testing doors and windows typically employ water spraying to simulate wind and rain conditions. This method tests the water tightness of doors and windows, especially exterior doors and windows, under simultaneous lateral wind and rain exposure, identifying potential leakage points such as profile joints, hardware mounting holes, sealing strip interfaces, and gaps in glass retaining strips. It also verifies whether the design, materials, processing, and installation quality of the doors and windows meet standards. However, in actual testing, existing direct spraying methods cannot adequately simulate natural wind and rain conditions, leading to distorted test results. Furthermore, conventional spraying devices suffer from incomplete coverage, resulting in poor testing effectiveness for different types of doors and windows.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a water spray testing device for the sealing performance of aluminum alloy doors and windows [202410411122.3], which includes a linear guide rail, a spray head mechanism slidably mounted on the linear guide rail, and a rope release and retraction mechanism for sliding the spray head mechanism on the linear guide rail; the linear guide rail has two sets, and the two sets of linear guide rails are symmetrically mounted on both sides of the outside of the door and window along the height direction, and there is a clearance gap between the linear guide rail and the most protruding part of the wall.

Water supply pipe. Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-4 As shown, a water spraying device for door and window inspection includes a water spraying pipe 1 arranged in a horizontal direction, water spraying heads 2 arranged at intervals along the axial direction on the water spraying pipe 1, a pressure regulating component 3 installed between the water spraying heads 2 and the water spraying pipe 1, and support frames 4 installed at both ends of the water spraying pipe 1.

[0024] Specifically, the support frame 4 is connected to a water pump via a water supply pipe 5, which in turn connects to the water spray pipe 1 via the support frame 4. A flow sensor and a pressure sensor are installed between the water supply pipe 5 and the water spray pipe 1. The flow sensor is used to monitor and record the total water spray flow in real time to ensure compliance with testing standards. The pressure sensor is used to monitor the water supply pressure at the inlet of the water spray pipe 1, providing feedback for the operation of the pressure regulating component 3.

[0025] Specifically, the water curtain spray head 2 includes a transfer pipe 21 connected to the water spray pipe 1. A spray pipe 22 perpendicular to the transfer pipe 21 is provided in the middle of the transfer pipe 21. A guide plate 23 is connected to the end of the spray pipe 22. The outlet of the spray pipe 22 is opposite to the inner side of the guide plate 23.

[0026] Furthermore, the width of the guide plate 23 gradually increases from one end near the jet pipe 22 towards the other end, and a flow-limiting edge 24 that folds inward is provided at the edge of the guide plate 23. This gradually expanding guide plate 23 design can diffuse the columnar water flow ejected from the jet pipe 22 into a uniform and continuous fan-shaped water curtain, covering a larger detection area; its inwardly folded flow-limiting edge 24 effectively constrains the edge of the water flow, preventing the water curtain from splashing and dispersing, ensuring that the edge of the water curtain is clear and falls vertically, forming a stable and well-defined simulated rainfall impact surface.

[0027] Furthermore, the pressure regulating component 3 includes a diversion valve 31 connected to the transfer pipe 21, which is connected to the other end of the transfer pipe 21 via a diversion pipe 32. The diversion valve 31 is essentially a bypass regulating valve. By adjusting its opening, the amount of water diverted from the transfer pipe 21 back to the water spray pipe 1 can be controlled, thereby precisely regulating the actual water pressure and flow rate entering the spray pipe 22 of the water curtain spray head 2. This ensures that the water output and water curtain pattern of each spray head 2 are uniform along the length of the water spray pipe 1, overcoming the difference in spray effect between the beginning and end of the spray due to pipeline pressure drop.

[0028] In addition, the support frame 4 includes a support base 41, with a vertically installed support pipe 42 inserted and fixed to the upper end of the support base 41. A tee connector 43 is connected to the upper end of the support pipe 42, and the tee connector 43 connects to the water spray pipe 1 or another support pipe 42. The support pipe 42 is fixed by insertion, facilitating adjustment of the installation height of the water spray pipe 1 according to the height of the door or window to be tested. The design of the tee connector 43 not only provides support for the water spray pipe 1 but also serves as a water flow channel, while allowing for height expansion by connecting another support pipe 42, forming a stable frame structure.

[0029] Meanwhile, the support base 41 is equipped with a water inlet pipe 44, which is connected to the support pipe 42. The water inlet pipe 44 introduces pressurized water provided by an external water pump into the support pipe 42. The water flows through the internal channel of the support pipe 42 and the T-joint 43, and finally enters the water spray pipe 1, forming a closed water supply path.

[0030] As can be seen, the water pipe 1 is made of stainless steel and is composed of several branch pipes 11, with water curtain spray heads 2 installed between the branch pipes 11. The stainless steel material ensures the corrosion resistance of the water pipe under long-term water spraying conditions. The use of branch pipes 11 greatly improves the modularity and flexibility of the device. The number of branch pipes 11 can be increased or decreased according to the width of the doors and windows to be tested, and water curtain spray heads 2 can be installed at any connection point of the branch pipes 11 to precisely match the joint positions of doors and windows.

[0031] Clearly, the branch pipe body 11 is threadedly connected to the water curtain sprinkler head 2, with a sealing ring installed between them. The branch pipe body 11 has an indicator scale. The threaded connection facilitates installation, disassembly, and maintenance, and the sealing ring ensures no leakage at the connection point. The indicator scale on the branch pipe body 11 is used to assist in accurately positioning the installation position of the water curtain sprinkler head 2 or measuring the sprinkler head spacing, ensuring accurate water coverage.

[0032] Preferably, the water spray pipe 1 is equipped with a flow limiting valve 12. The flow limiting valve 12 is usually installed at the water inlet end or key node of the water spray pipe 1 to set the maximum flow limit of the entire water spray system. As the last guarantee for flow control, it prevents damage to doors and windows or affect the accuracy of the test due to excessive water pump pressure or misoperation.

[0033] In summary, the principle of this embodiment is as follows: pressurized water is introduced through the inlet pipe 44 of the support frame 4, and then transported to the modularly assembled water spray pipe 1 via the support pipe 42 and the three-way connector 43. After the system flow limit is set by the flow limiting valve 12, the inlet pressure of each water curtain spray head 2 is dynamically controlled by the diversion valve 31 of the pressure regulating component 3. Finally, the water flows through the vertically set spray pipe 22 and impacts the gradually expanding guide plate 23. Under the constraint of the flow limiting edge 24, it diffuses into a continuous water curtain with clear boundaries and vertical uniformity, realizing standardized water spray detection of door and window joints. The flow sensor and pressure sensor monitor the parameters in real time to ensure that the water curtain shape and impact intensity meet the detection specifications.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] Although this document frequently uses terms such as water spray pipe 1, branch pipe body 11, flow limiting valve 12, water curtain spray head 2, adapter pipe 21, spray pipe 22, guide plate 23, flow limiting edge 24, pressure regulating component 3, diversion valve 31, diversion pipe 32, support frame 4, support base 41, support pipe 42, tee connector 43, inlet pipe 44, and water supply pipe 5, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
