63 output ends of water pump-64-water feeding tank of unloading valve 61 all the way, 63 output ends of another way water pump-check valve 67, check valve 67 are defeated
Outlet arrives pressure gauge 65 to the water pipe head 8 of 10 left end of cabinet, the end unloading valve A and pressure meter switch 66 respectively；The right side of cabinet 10
End face is equipped with overflow valve 68, and the bottom surface of cabinet 10 is equipped with a shut-off valve 69；Overflow valve 68 is connected with the output end of shut-off valve 69
To water feeding tank 61.
The course of work of water pressure control system: by the salt water in water feeding tank 61 through 62-water pump of filter, 63-check valve 67-
8-cabinet of water pipe head 10；When the pressure in cabinet 10 reaches the setting value of unloading valve 64, water pump 63 is exported through unloading valve 64
Start off-load work, cabinet 10 passes through 67 pressure maintaining of check valve；When the pressure in cabinet 10 is less than the close value of unloading valve 64, unload
Lotus valve 64 is automatically closed, and water pump 63 exports through check valve 67, water pipe head 8, continues to supply water to cabinet 10.
In addition, the effect of overflow valve 68 has two, one is mutually backups with unloading valve 64, plays safe valve action, that is, works as off-load
Valve 64 can not off-load, 68 automatic overflow of overflow valve, vice versa, it is ensured that system safety operation；Secondly being system emulation, when excessive
When the overflow value that stream valve 68 is set is less than the setting value of unloading valve 64, the hydraulic pressure in water tank 19 reaches the overflow of the setting of overflow valve 68
When value, system would operate in overflow situation, thus, it is possible to make the intracorporal pressure water of case under state of pressure keeping, natural imitation circle
The flowing being lauched.
