Accumulator safety shut-off valve is a new type of hydraulic components used in accumulators. It can be installed as a stop valve between the accumulator and the pipeline connected to the system, and has the functions of protecting the accumulator, such as pressure limiting protection, oil discharge and pressure relief. The valve body is provided with a pressure measuring oil port, which can detect the working pressure of the accumulator. This valve integrates functions of overflow, cut-off, unloading, etc., small size, light weight, simple and compact structure, easy operation and disassembly. Can greatly improve the service life and safety and reliability of the accumulator.
Advantages of accumulator safety shut-off valve:
1.Simple structure, easy to manufacture and maintain;
2. Small working stroke and short opening and closing time;
3. Good sealing performance, small friction between sealing surfaces and long life;
4. The structural form of the shut-off valve body includes straight-through type, direct-flow type and right-angle type. Straight-through type is a common structure, but its fluid resistance is large; DC-type fluid resistance is small, and it is mostly used for solid particles or high viscosity fluid . Right-angle valve bodies are mostly forged and are suitable for globe valves with smaller passage and higher pressure.
