Hull valve 14 enters in heat exchanger, is recycled with this, and high pressure sea water is avoided to introduce in cabin.
If the top area of piston 1401 is S1, downward active force is generated under hydraulic pressure effect.Above and below valve disc 1404
Face is acted on by hydraulic pressure, and the forced area of lower surface is more than upper surface forced area, and the difference of the two is the rank street area S of valve rod2,
Entire valve disc 1404 generates upward active force under hydraulic pressure effect.Spring 1403 is compressed spring, valve wide open in the present invention
When spring 1403 elastic force be F1, spring force is F when closing2。
Assuming that the pressure of outboard fresh water line is P, at valve rod 1402, the gravity of piston 1401 and valve disc 1404 and sealing
The additional forces such as frictional force and be F', work as F1≥P·(S1-S2)+F' when, valve is shown in a fully open operation；Work as F1<P·(S1-S2)+F'
When, valve is begun to shut off；Work as F2≤P·(S1-S2)+F' when, valve completely closes.
The fresh water line of outboard cooling system pressure in normal operation is relatively low, it is assumed that a certain specific outboard cooling system
The fresh water line operating pressure of system is up to P1, suitable spring is installed by selecting so that F1≥P·(S1-S2)+F', it is cooling
In normal operation, superpressure automatically cuts off hull valve and will be shown in a fully open operation system, does not influence system operation.
In shallower depth, if seawater pressure is less than P1, when underwater manned platform outboard pipeline occurs damaged, then
Fresh water line will leak, and superpressure automatically cuts off hull valve 14 and is shown in a fully open operation at this time；Operation control system is finding to manage
After the breakage of road, fresh water line can be cut off by hull valve in closing chamber, pipeline fresh water in cabin is prevented to be lost in, at this point, even if fortune
Row control system breaks down, and fails to close hull valve in time, and the accidents such as water inlet in cabin will not occur, do not influence underwater platform
Safety.
It is more than P1 in seawater pressure but is less than the depth of P2, when outboard pipeline breakage occurs for underwater manned platform, due to
F1<P2·(S1-S2)+F'<F2, superpressure automatically cuts off hull valve and can have an effect, but valve can not completely close.At this point, system
State and seawater pressure be less than P1The situation of Shi Fasheng outboards pipeline breakage is similar, can be cut off by hull valve in closing chamber
Fresh water line, even if failing to close hull valve in time, since system pressure does not exceed pipeline design pressure P in cabin2It will not
The accidents such as water inlet in cabin occur.
It is more than P in seawater pressure2Depth, when underwater manned platform occur outboard pipeline breakage when, due to F2≤P·
(S1-S2)+F', superpressure automatically cuts off hull valve and will close rapidly, cuts off outboard pipeline, prevents pipeline superpressure in cabin, intake
Accident.Flow is introduced the cavity first half by the high pressure sea water at specially damaged pipeline by drainage tube 1409, is made by hydraulic pressure
Piston 1401 generates downward active force, finally valve disc 1404 is driven to close the first communication port 1406, superpressure automatically cuts off topside
After valve is closed, at this time can relatively easily hull valve in closing chamber, increase the safety of system.
In addition, after superpressure automatically cuts off hull valve closing, the upper surface of valve disc 1404 will also act power, increase valve disc
1404 with the leakproofness of lower valve base 1405.
Under special circumstances, even if fracture distress occurs for the drainage tube that superpressure automatically cuts off hull valve, plunger shaft will be in outer
Boundary's seawater unicom, the mode of action of valve is constant at this time, and valve still has the function of that superpressure is automatically cut off, and will not cause cabin inner tube
Road superpressure.
When in slight depth breakage occurs for outboard pipeline, the cut-out pressure that superpressure automatically cuts off hull valve is not achieved in system
When, pipeline can be cut off by the hull valve in cabin；System pressure is relatively low at this time, is no more than the design pressure of pipeline in cabin, right
The operation control of hull valve requires relatively low in cabin, even if there are operating lag, breakage will not occur for pipeline in cabin.
It is the configuration of the present invention is simple, easy to use, it is super for fresh water line in the unexpected damaged, cabin of deep-sea outboard fresh water line
Situations such as pressure, can prevent water entering accident in cabin with quick response.The present invention is not take up space in cabin, when pipeline in generation cabin
When damaged, high pressure sea water can be completely cut off outside bulkhead, high pressure sea water improves safety in cabin without going past crossing cabin part.
