To ensure that the new production of valves and maintenance of the valve after the repair of a reliable seal the quality of the valve manufacturing and valve disassembly inspection repair the last step is the pressure test. The test method used should be based on national standards or international standards. American Standard (ANSI / ASME, API), German Standard (DIN), European Standard (EN) and International Standard (ISO) are the most commonly used standards. Pressure test bench testing on valve sealing performance can be divided into the following categories: Shut-off valves (gate valves, globe valves, ball valves, check valves, etc.) Control valves Safety valves Although the standards for pressure testing of valves vary, The type of valve, the detection method is roughly the same. The most important are the following: Detecting body strength; Testing the tightness of the valve body, stem and shaft coupling; Testing the seal of the seat or base, if possible; Determining the relief pressure of the safety valve. To achieve the maximization of benefits and the lasting benefits of maximum efficiency and stability are the goals of every health business. Providing high product quality at competitive prices is an effective way to require the cost-effective use of resources owned by the various businesses. The economic effectiveness of valve testing means that testing a wide range of valves using a wide range of standards at the lowest cost and expense means that it is not only ideal but also ideal for valves of the same valve but different manufacturers test. Only 100% inspection ensures the reliable quality of each valve. To achieve this goal, an automated valve inspection method should be used and the degree and level of automation should be adapted to the manufacturer's production line and manufacturing process. Today, in most cases, the valve manufacturing process is highly automated and the potential for cost reduction is slim. Therefore, the stochastic manual sampling method is not only technically backward but also economically impossible. 100% of the tests require a highly automated inspection system. Valve automatic test valve should be connected with the automatic production line, but also requires the completion of testing within the specified time. Simplify the operation of the valve clamping device, simultaneous testing of multiple valves, automatic recording of test results are very effective method. In the past, some valve manufacturers manufactured their own valve test systems. Today, this work has been handed over to professional manufacturers to complete. Because of the professional manufacturers through the use of standardized modules and components and users designed specifically for the manufacture of modules and components to achieve the specific needs of each user. Professional manufacturers of valve inspection equipment provide valve manufacturers with many cost-effective valve test automation solutions. Valve test bench for valve leakage test, body strength test and other functional tests. Each valve test stand must be filled by the user needs checklist, audited, standard or special design and manufacture. Although the pressure test valve test standards vary, but for each type of valve, the test method is roughly the same. The most important are the following: Detection type: valve sealing test and stem leakage test; water body tightness test; switch tightness test; safety valve take-off value test; test objects: gate valve, globe valve, safety Valve, throttle valve, check valve, swing check valve, ball valve, regulating valve and other hollow pump body, body and shell, etc .; Valve connection: flange connection, screw connection, welding connection; . Water, Air, Nitrogen EFCO has two mobile and stationary inspection stations, of which two are mobile, PS T 10 and PS T SV 5. The stationary units are all configured on demand and are produced on demand, with the following For some typical configurations, other types are customized for EFCO according to user needs.
