Super Valve Test Bench

Jan. 13, 2020

In order to ensure the reliable sealing quality of newly produced valves and valves after inspection and maintenance, the last step after valve production and valve disassembly inspection and maintenance is pressure test. The detection method used should be 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. Valve test bench supplier share with you:

Valve pressure test table test classification can be divided into the following categories: cut-off valve (gate valve, globe valve, ball valve, check valve, etc.), control valve, safety valve, although the valve pressure test standards vary The same, but the detection method is roughly the same for each type of valve. The most important ones are: testing the strength of the valve body; testing the tightness of the valve body, stem and shaft joint; testing the tightness of the seat or base (if possible); determining the take-off pressure of the safety valve. Achieving maximum benefits and lasting and stable maximum benefits are the operating goals of every healthy enterprise. Providing high-quality products at competitive prices is an effective method, which requires cost-effective use of resources owned by various enterprises. The economic effectiveness of valve testing means that at the lowest cost and cost, it is possible to test a variety of valves using a variety of standards.Not only that, but ideally, valves of the same valve type but different manufacturers can also be tested. test. Only 100% inspection can ensure the reliable quality of each valve.

To achieve this goal, automation should be used, and the degree and level of automation should be compatible with the manufacturer's production line and production process. Today, in most cases, the valve production process is highly automated and the potential for cost reduction is minimal. Therefore, the random manual sampling detection method is not only technically backward, but also no longer economically feasible. 100% testing requires highly automated inspection systems. The automatic valve test should be connected to the automatic valve production line, and the inspection should be completed within the specified time. Simplifying the operation of valve tightening and mounting, simultaneous testing of multiple valves, and automatic recording of test results are all very effective methods. In the past, some valve manufacturers built their own valve test systems. Today, this work has been done by professional manufacturers. Because professional manufacturers can use standardized modules and components and modules and components specially designed and manufactured for users to achieve the specific needs of each user. Valve test equipment professional manufacturers can provide valve manufacturers with many very economical and practical valve test automation solutions. The valve test bench is used for valve leak test, valve body strength test and other functional tests. Each valve test rig must be made according to the requirements filled by the user, after being audited, with standard or special design. Although the valve pressure test standards are different, the test methods are roughly the same for each type of valve. The most important are the following: Detection types: valve tightness test and stem leak test; underwater valve body tightness test; switch tightness test; safety valve take-off value test; test objects: gate valve, globe valve, safety Valves, throttles, check valves, swing check valves, ball valves, regulating valves and other hollow pump bodies, valve bodies and housings, etc .; Valve connection methods: flange connection, screw connection, welding connection; detection medium . Water, air, nitrogen.
