The valve testing bench is a new generation JWZ hydraulic valve testing bench designed and improved on the basis of valve testing equipment technology in accordance with the standard specifications of GB/T13927-92 General Valve Pressure Testing and ZBJl6006-90 Valve Testing and Inspection. Integrating electromechanical, hydraulic, pressure testing, and liquid medium storage and circulation, it has the characteristics of complete functionality, stable performance, and high degree of automation.
1. JWZ pressure holding type: suitable for flange connected ball valves, globe valves, gate valves, check valves, etc
2. JWT top pressure type: suitable for welding threaded high-pressure valves, etc
3. JWZQ water immersed: suitable for ball valves, globe valves, gate valves, check valves, etc. in pneumatic operations
4. JLD gripping type: suitable for various butterfly valve testing.
5. Pneumatic sample: suitable for valves with threaded and flange connections
6. JLT vertical: suitable for valves with threaded, welded, and flange connections
7. Valve torque and life testing machine: suitable for flange connected valves
8. Intelligent type: equipped with PC or PLC, test results can be statistically analyzed, compared, and printed, with high accuracy
The valve testing bench and valve testing equipment are used to ensure the reliable sealing quality of valves and valves after inspection and maintenance. The next process after valve production and valve disassembly and maintenance is pressure testing. 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 all commonly used standards. The pressure testing bench for valve sealing performance can be divided into the following types: cut-off valves and welded valves. Although the standards for valve pressure testing are different, the testing methods are generally the same for each type of valve. The following are very important: testing the strength of the valve body; Check the sealing degree of the valve body, valve stem, and valve shaft connection; Check the sealing degree of the valve seat or base (if possible); Determine the take-off pressure of the safety valve. Achieving lasting and stable benefits is the business goal of every healthy enterprise.
