2507 vertically downward, and porus excretorius 2507 is kidney slot.
It converges the setting of liquid bath 2509, is for storing the water leaked out from cabinet 10 through E sealing ring 26, and from hydraulic
The oil that cylinder 29 is leaked out through F sealing ring 28；After avoiding the remittance storage of liquid bath 2509 full, water and hydraulic cylinder 29 in cabinet 10
Interior oil is ganged up mutually, end cap 25 provided with porus excretorius 2507, the present apparatus in four square sides up and down of end cap 25,
Be equipped with a porus excretorius 2507 always has the aperture of a porus excretorius 2507 to arrange downwards after that is, end cap 25 is fixed to cabinet 10
Liquid, while upward hole can be used as port, left and right Kong Jike with drain can also with intake and exhaust, guarantee to converge liquid bath 2509 with
Atmosphere, and air pressure balance is kept, and it is unobstructed that porus excretorius 2507 is drained, realize an end cap two way seal.
As shown in figure 5, the water pressure control system, including water feeding tank 61, filter 62, water pump 63, unloading valve 64, check valve
67, overflow valve 68,63 input terminal of water pump are connected by filter 62 with water feeding tank 61,63 output end of water pump point, two tunnels, all the way water pump
63 output ends-unloading valve, 64-water feeding tank 61,63 output ends of another way water pump-check valve 67,67 output end of check valve difference
Pressure gauge 65 is arrived to the water pipe head 8 of 10 left end of cabinet, 64 control terminal of unloading valve (end A) and pressure meter switch 66；Cabinet 10
Right side is equipped with overflow valve 68；The output end of overflow valve 68 is connected 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,
Unloading 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 overflowing for the setting of overflow valve 68
When flow valuve, 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 of underground water.
