In order to ensure the reliable sealing quality of the new production valve and the valve after inspection and maintenance, the final process after the valve production and valve disassembly inspection is the pressure test. The test methods used are based on national or international standards. American standards (ANSI/ASME, API), German standards (DIN), European standards (EN), and international standards (ISO) are the most commonly used standards.
The pressure test bench test classification can be divided into the following types: cut-off valves (gate valves, globe valves, ball valves, check valves, etc.), control valves, safety valves, although the standards tested by the valve test bench are different, but for each type For the valve, the detection method is roughly the same. The most important are the following: Detecting the strength of the valve body; detecting the sealing degree of the valve body, the stem and the valve shaft joint; detecting the sealing degree of the valve seat or the base (if possible); determining the take-off pressure of the safety valve. Maximizing benefits and maximizing the benefits of sustainability are the business objectives of every healthy business. Providing high-quality products at competitive prices is an effective way to cost-effectively use the resources that companies have. The economic viability of valve testing means that it is not only the case that various types of valves are tested using various standards at the lowest cost and cost. Ideally, valves of the same valve type but different manufacturers can be implemented. test. Only 100% inspection ensures the reliable quality of each valve.
To achieve this goal, automation should be employed and the level and level of automation should be compatible with the manufacturer's production line and production process.
