Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve body testing fixture technology, and more specifically, to a testing multi-way water valve fixture. Background Technology
[0002] With the development and widespread adoption of new energy vehicles, robotic products, and fast charging for energy storage stations, multi-port water valves, as a crucial integrated component in their thermal management systems, are increasingly being used. Simultaneously, due to the complex application scenarios of multi-port water valves, the technical requirements for their development are becoming increasingly stringent. This has driven water valve suppliers to conduct more comprehensive lifespan durability tests to verify their products. Current lifespan durability tests for water valves cover aspects such as resistance to pressure changes, temperature changes, coolant corrosion, impact from impurities, burst damage, and vibration to verify product durability and meet development technical requirements.
[0003] Conventional thermal management multi-port water valve life durability tests are conducted by installing the valve onto an integrated module. The durability test process involves synchronous pressure and flow supply via a module-mounted water pump. This method, which operates by sending signal commands through the integrated module, has drawbacks such as the requirement for synchronized control of the water valve and pump, a complex overall structure leading to numerous interference factors in process monitoring and analysis, and a large overall space requirement in the test chamber.
[0004] Similarly, conventional thermal management multi-way water valve life durability tests or multi-channel tooling combined with electric valves and pressure pumps for linkage durability tests have the problem of multi-loop control, which leads to more complex equipment structure and control logic and relatively higher energy consumption. Utility Model Content
[0005] The purpose of this application is to provide a multi-way water valve tooling for testing, which has the advantages of simple structure, high testing efficiency and strong adaptability.
[0006] This application provides a test multi-way water valve fixture, comprising: a fixture body having a test inlet connector and a test outlet connector thereon; a positioning part disposed on the top of the fixture body for positioning in conjunction with the multi-way water valve; and a connecting part for detachably fixing the multi-way water valve to the fixture body; wherein the fixture body has multiple inlet channels and multiple outlet channels inside, the two ends of the inlet channels being respectively connected to the test inlet connector and the inlet end of the multi-way water valve, and the two ends of the outlet channels being respectively connected to the test outlet connector and the outlet end of the multi-way water valve, and the inlet channels and outlet channels being isolated from each other.
[0007] Compared with existing technologies, the multi-way water valve fixture proposed in this application has the following advantages: The fixture integrates a test inlet connector, a test outlet connector, a positioning part, and a connecting part to form a test unit, eliminating the need for complex integrated modules or multi-loop linkage equipment, simplifying the test system structure and reducing space occupation; the inlet and outlet channels are isolated from each other, ensuring independent flow of water in and out of the multi-way water valve, avoiding mutual crossflow interference, and improving the accuracy of test data; during the branch performance test of the multi-way water valve, only the multi-way water valve needs to be adjusted, reducing external control and improving test efficiency; the connecting part allows for detachable fixing of the water valve and the fixture, facilitating quick replacement of test samples and improving test efficiency.
[0008] In one possible implementation, the positioning part includes at least one positioning hole, the size of which matches the positioning pin of the multi-way water valve. Compared with the prior art, the matching of the positioning hole with the positioning pin of the water valve enables rapid positioning during water valve installation, ensuring accurate alignment of the water valve's inlet and outlet ends with the internal channels of the tooling, and avoiding fluid leakage or testing errors caused by installation deviations.
[0009] In one possible implementation, the positioning part includes at least one positioning post, the size of which matches the positioning groove of the multi-way water valve. Compared with the prior art, the matching of the positioning post with the water valve positioning groove provides an alternative positioning solution for water valves with positioning groove structures, ensuring accurate docking of the water valve's inlet and outlet ends with the internal channels of the tooling, and avoiding fluid leakage or testing errors caused by installation deviations.
[0010] In one possible implementation, the connecting part includes a mounting panel and multiple mounting screws. The mounting panel is integrally connected to the fixture body. The mounting panel has threaded holes corresponding to the mounting holes of the multi-way water valve. The multi-way water valve is fixed to the fixture body by passing the mounting screws through the mounting holes and screwing them into the threaded holes. Compared with the prior art, the combination of the mounting panel and mounting screws provides mechanical fastening force, ensuring that the water valve remains fixed during high-pressure fluid impact or long-term testing, preventing it from falling off or loosening. The screw connection method supports quick disassembly, facilitating cleaning and maintenance of the water valve or the internal channels of the fixture after testing, reducing maintenance costs. The threaded hole design corresponds to the water valve mounting hole, adapting to the standardized installation interface of mainstream water valves and improving the versatility of the fixture.
[0011] In one possible implementation, the fixture body is provided with multiple test holes for mounting pressure sensors, temperature sensors, or flow sensors. Compared with existing technologies, the test holes can directly mount pressure, temperature, and flow sensors, enabling real-time acquisition of fluid parameters in each pathway. This provides support for dynamic analysis of experimental data and replaces the complex traditional method of indirect monitoring relying on integrated modules.
[0012] In one possible implementation, the main body of the tooling is a one-piece structure made of corrosion-resistant alloy or 3D-printed plastic. Compared with existing technologies, corrosion-resistant alloy or 3D-printed plastic materials can resist long-term erosion by media such as coolant and water, extending the service life of the tooling. This makes it suitable for highly corrosive testing environments and avoids channel blockage or structural failure caused by corrosion in traditional metal materials. The one-piece structure reduces splicing gaps, improves the overall strength and vibration resistance of the tooling, maintains stability in high-frequency vibration or high-pressure cyclic testing, and reduces the probability of failure due to structural fatigue.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] See Figure 1 and Figure 2 This application discloses a test multi-way water valve fixture, comprising: a fixture body 1, on which a test water inlet connector 2 and a test water outlet connector 3 are provided; a positioning part, disposed on the top of the fixture body 1, for positioning in conjunction with the multi-way water valve; and a connecting part, for detachably fixing the multi-way water valve to the fixture body 1; wherein, the fixture body 1 is provided with multiple water inlet channels 11 and multiple water outlet channels 12, the two ends of the water inlet channels 11 are respectively connected to the test water inlet connector 2 and the water inlet end of the multi-way water valve, and the two ends of the water outlet channels 12 are respectively connected to the test water outlet connector 3 and the water outlet end of the multi-way water valve, and the water inlet channels 11 and the water outlet channels 12 are isolated from each other.
[0025] The tooling body 1 can be made of corrosion-resistant alloy or 3D printed plastic material, and its internal flow channel can be formed by machining; the test water inlet connector 2 and the test water outlet connector 3 can be made of quick-connect connectors, flange connectors or threaded connectors.
[0026] In this embodiment, the positioning part includes two positioning holes 4, the size of which matches the positioning pin of the multi-way water valve. Specifically, the number of positioning holes 4 can be designed according to the positioning requirements of the multi-way water valve; the diameter and depth of the positioning holes 4 must precisely match the size of the positioning pin of the multi-way water valve to ensure alignment accuracy during assembly. Thus, by setting positioning holes 4 that match the positioning pin of the multi-way water valve, rapid and accurate positioning of the tooling body 1 and the multi-way water valve can be achieved.
[0027] In this embodiment, the connecting part includes a mounting panel 6 and multiple mounting screws. The mounting panel 6 is integrally connected to the fixture body 1. The mounting panel 6 has threaded holes 61 corresponding to the mounting holes of the multi-way water valve. The multi-way water valve is fixed to the fixture body 1 by screwing the mounting screws through the mounting holes and into the threaded holes 61. Specifically, the mounting panel 6 and the fixture body 1 adopt an integral molding structure, thereby ensuring connection strength and avoiding the risk of fluid leakage. The position of the threaded holes 61 is designed to match the standard mounting hole position of the multi-way water valve. The mounting screws are preferably made of stainless steel, and their length must be sufficient to penetrate the mounting hole of the multi-way water valve and form an effective engagement with the threaded holes 61. In this way, the modular threaded connection structure enables quick assembly and disassembly of the multi-way water valve and the fixture body 1.
[0028] In this embodiment, the fixture body 1 is provided with multiple test holes 13, which are used to install pressure sensors, temperature sensors, or flow sensors. By providing test holes 13 on the fixture body 1, various sensors can be directly installed for real-time monitoring, solving the problems of large measurement errors and inconvenient installation caused by the need for external sensors through complex pipelines in traditional tests. This design simplifies the structure of the test device, improves testing efficiency and reliability, and provides more accurate data support for the performance testing of multi-way water valves. If no sensor is installed, the test holes 13 can be plugged to prevent leakage from the fixture body 1.
[0029] This application provides a test multi-way water valve fixture, the advantages of which are mainly reflected in the following aspects:
[0030] 1. By integrating the test inlet connector 2, the outlet connector, the positioning part and the connecting part into the main body of the tooling 1, an independent test unit is formed. It does not need to rely on complex integrated modules or multi-loop linkage equipment, which significantly simplifies the structure of the test system and reduces space occupation.
[0031] 2. The internal water inlet channel 11 and water outlet channel 12 are isolated from each other to ensure independent flow in each passage of the multi-way water valve, avoid cross-flow interference, and improve the accuracy of test data; the positioning part is precisely matched with the multi-way water valve to achieve rapid alignment and installation, and reduce leakage or test errors caused by deviation.
[0032] 3. The connection part adopts the combination of mounting panel 6 and screws, which supports quick disassembly and assembly of multi-way water valves, making it convenient for sample replacement and maintenance; the threaded hole 61 is designed to adapt to standardized interfaces, improving the versatility of tooling.
[0033] IV. Test holes are provided on the main body of the tooling 1, which can be used to directly install pressure, temperature or flow sensors to collect data in real time and simplify the monitoring process.
[0034] V. The main body of the tooling is made of corrosion-resistant alloy in one piece, which has strong corrosion resistance and is suitable for highly corrosive environments; the one-piece structure reduces gaps, enhances overall strength and vibration resistance, and ensures stability in high pressure or vibration tests.
[0035] Example 2
[0036] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the positioning part includes four positioning posts 5, the dimensions of which match the positioning groove of the multi-way water valve. Specifically, the positioning posts 5 can adopt a cylindrical structure and be integrally set on the tooling body 1, with threaded holes 61 located at the top of the positioning posts 5. That is, by setting positioning posts 5 that match the positioning groove of the multi-way water valve, the tooling and the water valve are positioned quickly and accurately.
[0037] Example 3
[0038] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the main body of the tooling 1 has a disc-shaped structure, which is suitable for testing multi-channel disc water valves.
