As an indispensable part of the toilet, because of its particularity in application, people have higher requirements on the waterproof of the toilet inlet valve, that is, it is required to have higher precision, and it is also required to have waterproof. If its waterproof degree is poor, it will affect the normal use of the toilet. Hiris technology has carried out in-depth research on the waterproof test in various fields, and also involves the waterproof test of the toilet inlet valve. This time, we will share the waterproof test of the toilet inlet valve, hoping to give you a reference.
1、 Inspection requirements of toilet inlet valve
1. The shape of the toilet inlet valve is rod-shaped, the top is the valve buckle for connection, and the right is the blue air valve. The shape is irregular and the volume is relatively large, so it is not convenient to make a test mold for the product. At the same time, the water inlet valve has a water inlet, so we can use the water inlet of the product to intake air. This kind of direct inspection method can not only test accurately, but also save the cost of die.

2. According to the customer's requirements, the toilet inlet valve should not only test the tightness of the product, but also test the internal pressure of the product. The use environment of inlet valve should not only be waterproof. At the same time, the internal air pressure of the inlet valve can only be used within a certain range. For this reason, Harris customized this three channel pressure + flow waterproof testing equipment for customers. After a month's continuous research, we have finally made a test equipment that satisfies our customers. This also provides a prospective reference for the test of the toilet inlet valve.
2、 Waterproof test of toilet inlet valve
1. First of all, according to the shape and structure of the toilet inlet valve, Harris customized a special detection scheme for it. Because the structure of the toilet inlet valve is interconnected, the water resistance of the toilet inlet valve can be detected by filling gas into the toilet inlet valve in a fixed way;

2. The testing quantity is three each time. The three channel waterproof testing instrument customized by Harris technology for customers uses the multi-channel waterproof testing instrument, which can realize the simultaneous testing of multiple products without any impact on the accuracy and stability of the testing. It saves time and reduces the cost of waterproof testing;

3. During the detection, the instrument will inflate the water inlet valve of the toilet through the upper part. If the water inlet valve of the toilet is unsealed and air leakage occurs, the leakage value in the instrument will be larger and larger, and the pressure value will drop. At this time, it can determine whether the toilet inlet valve is leaking, and the instrument test results will also show ng, which means that the air tightness test fails. If the water inlet valve of the tested toilet does not leak, the gas in the tooling die will be in a constant state after inflation, the pressure value and leakage value displayed on the instrument are also stable, and the test result of the instrument will display "OK", indicating that the waterproof test has passed.
3、 Advantages of using three channel waterproof tester
(1) Save time and cost; The detector can provide three detection channels and detect three toilet inlet valves at the same time. The test speed is three times faster than usual, which is more conducive to saving time and cost. It has set a precedent for the market.
(2) Lower equipment cost; The three channel water-proof tester is controlled by three testing equipment, and three stations are used for sealing test. It only needs one person to operate, which simplifies the manpower for the enterprise and optimizes the capital chain of the manufacturer.
(3) It has strong operability and high efficiency; The tester is also equipped with "positive and negative" pressure forms and 8 Basic test modes, which can be selected or combined. Using 24 bit a / D conversion, 32-bit CPU operation, and fully independent development of industrial control operating system, with full touch human-computer interface. Built in RS232 serial port, RJ45 network port, USB communication interface, LTP external I / O control port, support a variety of communication protocols, diversified self-service operation, artificial and intelligent combination, enhance the operability of the device.
