Description

Technical Field

[0001] This utility model belongs to the field of automated testing technology, specifically relating to a testing fixture for the function of solenoid valves and push-button faucets. Background Technology

[0002] With the rapid development of modern technology, automated testing technology is increasingly widely used in various industries. In particular, in the manufacturing and quality control of bathroom products, the functional testing of solenoid valves and push-button faucets has become an indispensable link. As a key component for controlling the flow of fluid, the solenoid valve's sealing performance, opening and closing function, and pressure resistance directly affect the stability and safety of the entire system. As a water flow control device directly operated by the user, the push-button faucet's sealing performance, water flow switching performance, and pressure resistance are equally important, especially in high-end application scenarios such as high-speed rail, where the requirements for product quality and reliability are even more stringent.

[0003] In the traditional production process of bathroom products, the functional testing of solenoid valves and push-button faucets mostly relies on manual operation. This method is not only inefficient, but also makes it difficult to guarantee the accuracy and consistency of the tests. In order to improve testing efficiency and product quality, the industry has begun to explore automated testing technology. At present, some automated testing equipment for bathroom products has appeared on the market. However, these devices are often single-function, only testing a specific function of solenoid valves or push-button faucets. Moreover, most of them are geared towards general bathroom products and have not been optimized for specific application scenarios such as high-speed rail. In addition, when testing solenoid valves, these existing devices usually use a single type of solenoid valve base, which cannot simultaneously meet the testing requirements of direct-acting zero-differential pressure solenoid valves and pilot-operated solenoid valves, thus limiting the testing range and accuracy. At the same time, when testing push-button faucets, they also lack the ability to simulate the hot and cold water mixing function under real-world usage scenarios, as well as the corresponding real-time water pressure monitoring function, resulting in a certain deviation between the test results and actual applications. Therefore, improvements are needed. Utility Model Content
