1、 Types: There are various types of valve test benches that can be classified according to different testing needs. Generally speaking, valve test benches can be classified in the following ways:
1. Hydraulic valve testing bench: Using hydraulic oil as the testing medium, it is mainly used to test the performance parameters of hydraulic valves.
2. Pneumatic valve testing bench: Using gas as the testing medium, it is mainly used to test the performance parameters of pneumatic valves.
3. Electric valve testing bench: It is driven by an electric motor and is mainly used to test the performance parameters of electric valves.
4. Manual valve testing bench: Using manual operation for testing, mainly used to test the performance parameters of manual valves.
In addition, there are also some valve testing benches with complex structures, such as fully automatic valve testing benches, multifunctional valve testing benches, etc.
2、 Structural features: The valve test bench is a device used to test the sealing performance and pressure resistance test performance of valves. Its main structure includes installation base, workbench, locking fixture, pressure mechanism, and control system. Its working principle is as follows:
1. Installation base: The installation base is the supporting structure of the entire test bench, used to fix all components of the test bench.
2. Workbench: The workbench is the location where valves are installed, usually consisting of a workbench and a fixed table. The workbench can be adjusted from different angles to meet the testing needs of different types of valves.
3. Locking fixture: The locking fixture is used to secure different types of valves. It usually adopts an adjustable design to ensure that valves of various specifications and sizes can be fixed.
4. Pressure mechanism: Pressure mechanism is an important part of valve sealing performance and pressure resistance test performance testing. It tests the sealing performance and pressure resistance test performance of the valve by controlling the pressure of water or gas.
5. Control system: The control system is used to control various parameters of the test bench, such as pressure, time, and temperature, to ensure the effectiveness and reliability of the test.
In summary, the structural principle of the valve testing bench is composed of installation base, workbench, locking fixture, pressure mechanism, and control system to test the sealing performance and pressure resistance test performance of the valve.
