| titleOfInvention | Cartridge type two-position four-way water hydraulic reversing valve |
| abstract | The invention discloses a cartridge type two-position four-way water hydraulic reversing valve, which comprises two groups of normally open cartridge valve units, two groups of normally closed cartridge valve units, a cover board, a main valve body and a two-position three-way forerunner electromagnetic ball valve, wherein the cartridge valve units have three-stage concentric structures; and the forerunner control cavities of the four cartridge valve units are communicated with the water outlet of the forerunner electromagnetic ball valve through a hole in the valve body. By the cartridge type two-position four-way water hydraulic reversing valve, the problems of high leakage, easy dead lock, corrosion of a valve opening and the like in the water hydraulic system during adoption of the conventional two-position four-way slide valve and the problems of complicated structure, low reliability, reversing impact caused by synchronous control precision and the like which are caused by two two-position three-way forerunner electromagnetic ball valves adopted in the conventional cartridge valve structure can be solved. The cartridge type two-position four-way water hydraulic reversing valve has the characteristics of high through-flow capacity, high sealing property, high sensitivity, high anti-pollution capacity and compact structure, can reverse stably at high speed. The cartridge type two-position four-way water hydraulic reversing valve is particularly suitable for large-flow hydraulic systems which take sea water, desalted water and high water base and low viscosity liquid as transmission media. |
