PATENT OFFICE.

The subject of the present invention are innovations in apparatus for opening and closing of bulkhead doors, valves and other devices from a central point from, as is the case with ships, factories and other similar systems is desirable. The purpose of the invention is primarily to make the apparatus to make it as simple, permanent and inevitable as possible, so that a permanent one Reliability of the same is assured.

A further aim of the present invention is to create a system in which the power required to operate a number of different mechanical devices these individual apparatuses are fed through a single main line and this is the pressure is always maintained at a certain level in the line. Furthermore is still Care has been taken to ensure that each individual device operates independently of the other can be taken and controlled.

The device is shown in the accompanying drawing, which shows:

Fig. Ι a schematic representation of the primary system, which with an accumulator is connected for supplying fluid pressure to the main line and its Branch lines;

Fig. 2 shows the front view of a vertically sliding bulkhead door that is connected to the new System is equipped for opening and closing;

¹ Fig. 3 is a section through the regulating valve and the cylinder moving the bulkhead door;

Figure 4 is a section taken in the direction of line 4-4 of Figure 3. |

In Fig. 1, A denotes a steam boiler, or a pressure collector, in which the pressure fluid necessary to operate the accumulator pumps is generated or. is stored. In the present case, A represents a steam boiler. From this, the steam, which is under high pressure, is passed through the pipe α to a reducing valve a ' , through which it is for example to 8 atmospheres. is held. In normal operation, the vapor pressure is reduced to about half, i.e. 4 atm, by a second reducing valve a ' ^{1, which is switched on after the first one.} Voltage, is reduced and is now directed into a container A ¹ . The condensation water is separated in this. From here the steam flows through the pipe α ³ to the steam cylinders of the accumulator pumps A ³ . Is used instead of the vapor compn'mirte air or the like., The container A ¹ is superfluous and then is the line a ^s by the dotted lined pipe a direct ° with the second Reducirventil a ¹ in connection. In cases of emergency, in which all bulkhead doors, valves or other devices to be moved from a central point are to be closed at once, the steam coming from the first reducing valve a ^{1 is} 8 atm. Voltage conducted directly to the steam cylinders of the accumulator pumps A * , as a result of which the pumps must produce a pressure twice as high for the instantaneous purpose. The steam of: 8 atm. Tension is created for this purpose by a

pipe a ° branching off directly behind the first reducing valve a ^{1 led} directly to the line a ³ after the cock a ¹ switched on in the pipe α ^{β has} been opened. Usually, however, the ^{valve α 7 is} closed, so that the steam has to pass the second reducing valve a ² .

The accumulator pumps A ³ suck in the necessary water through the pipe α ⁴ and press it under a corresponding pressure through the line α ⁵ into the hydraulic accumulator A ² . From the latter, it is conducted through a main line B to the individual branch lines b , through which the relevant devices are fed.

The lever of the cock a ¹ is connected to the piston of the cylinder C , which can be actuated by a hydraulic system of the type protected by patent specification No. 96097; this system consists of two cylinders C and C ¹ of equal size, connected to one another by tubes c . The tubes c lead through a six-way cock C ² and are provided with pressurized water through the supply ^{tube c 3;} the latter can either be connected to the hydraulic cylinder A ² , as indicated in dotted lines in FIG. 1, or a special pressurized water tank can be provided. c ⁴ is the drain line.

During the movement of the piston in cylinder C, the cock a ⁷ must open or close, whereby the liquid driven out through one end of the cylinder causes a movement of exactly the same size of the piston in cylinder C ¹ , which movement is caused by one with the Piston rod connected pointer c ^{l is} indicated on a scale c ² . The six-way cock C ² is provided with a lever C ³ and a handle C ⁴ , by means of whose cover the pressurized water can be brought to each side of the cylinder C and thus the cock a ^{1 can be} opened and closed.

The primary system described in this way forms the safety device in the event of a sudden accident. The six-way cock C ² is attached to the command bridge or in another easily accessible place on the ship, and if all the doors are to be closed at once, a simple movement of the lever C ³ is sufficient. As a result of this movement, the valve α ^{7 is} opened while the cylinder C is mingled, and twice as high a pressure is produced in the line B and in the branch lines b , which, as can be seen from the following, closes all doors and / or. Devices causes.

In Figs. 2 and 3 is a vertical sliding ; Bulkhead door, equipped with the new system, shown, which is particularly suitable for Use of the present sleeping system is suitable.

In these figures, D is the door which slides in vertical guides E. With the door D , a cylinder F is attached by means of suitable plates / and bolts / ', which protrudes slightly over the bulkhead door. A hollow piston F ^{1 is} arranged inside the cylinder (FIG. 3), the 'hollow piston rod F ^{2 of which} passes through the cylinder cover F * and an ordinary pack / ⁴ . Said piston rod is connected to the bulkhead a little above the door by means of a console and flange piece X ¹ . The hollow piston rod F ² opens into the cylinder above the piston by means of a small side edge f ² . Inside the hollow piston rod F ² there is a smaller tube F ^{s in} such a way that an annular space / ⁰ remains between the inner and outer tubes; this tube F ³ passes through the piston and opens on the lower side of the piston at f ^s into the cylinder F. .i

The upper ends of the two tubes F ² and F ³ open into a cast piece G, into which the ends of the two tubes H and H ^} are inserted in such a way that they guide the liquid into the cylinder F by means of the cast piece and the tubes. The pipe H is in direct communication with the inner pipe F ³ through the channel g , while the liquid from the pipe H ¹ is fed through the channel g ^{l to} the outer pipe f ^2. Thus, when the pressure fluid enters the pipe H , it must pass through the inner pipe F ³ into the lower part of the cylinder F and thus press the cylinder F downwards; this closes the door firmly connected to the cylinder. When the liquid is fed through the tube H ¹ , it must get into the cylinder F above the piston and raise the door accordingly. The direction of the liquid in the pipes H and H ¹ is controlled by the tap K.

This cock K consists of a housing AT ¹ which is drilled in the direction of its axis in such a way that a chamber k ° is created; the cock plug / is sealed in this. The tap housing is inserted watertight into the bulkhead in such a way that the cock plug can be operated from both sides of the bulkhead door.

Lever / 'and I ² sit on the ends of the cock plug / . The various pipes are connected to the housing by the screw connections L. The tubes H and H ¹ enter diametrically opposed openings of the housing K ¹ and open

in channels / ι and / ι ¹ , which lead into the cock 'housing k ° . The branch pipe b of the main line is led into the channel b ^{l of} the valve housing, which opens into the valve chamber k ° at right angles to the openings h and / i ^1. The outlet channel h ² in the tap housing is diametrically opposite channel b} and is connected to the outlet pipe H ² ; this is connected to the lower side of the housing K ¹ by the screw connection L and lies on one side of the tube H ¹ . On the other side of the tube H ¹ , a tube H ³ opens into the valve housing through a channel h ³ which runs out into the channel b ^l. The pipe H ³ leads to an auxiliary supply, for example a hand pump M ¹ , by means of which the liquid can be pressed from the container M through the pipe H ³ and the valve K to the cylinder F , m represents the overflow pipe of the container M to to be able to drain the fluid when the container is full. The cock plug 1 is provided with two channels i and z ' ¹ which pass transversely through the plug; the openings of these channels are each offset from one another by 90 °, so that if the plug is rotated, the channel / connection between the channels b ^l and h prepared while the other Durchlafs / 'a connection between the channels / 1 ¹ and Λ ² produces, in this position must, the liquid from the main line b through the tubes H and ^F in 'the lower part of the cylinder reach and the door conclude, while the liquid from the upper part of the cylinder through the tubes F' ² and H \ passes the channel / 1 ^{1 of} the housing, the passage i ^l of the plug and the channel h ² after the outlet pipe H ² and from here into the container M. If the cock plug is moved to the other position, then the channel b ^l of the main line b must be connected to the channel / 1 ¹ , so that the liquid wedge through the pipes H ¹ and F ² to the upper side of the cylinder over the piston F ¹ arrives and thus called cylinder, drives upwards and opens the door. The liquid from the lower part of the cylinder then must, through the tubes F ³ 'and H, the channel h, i said passageway and the channel /) ² after Auslafsrohr H' pass ² "in the container M. The rotation of the cock K can be done by hand in order to be able to open the bulkhead door in special cases, e.g. when people from one department want to go to the other, but the valve housing is also included in order to be able to direct the movements of the bulkhead door from the central station Chambers K ² and K ^3. The chamber K ² is connected to the channel b ^x via a bore Ic ² , which the latter is usually kept closed by a check valve K * and spring Ä ^4. The tension of this spring is Λ * so dimensioned that, if only the normal pressure is present in the line b , the passage Ic ^{2 is} kept closed; at higher pressure it rises from its seat. A channel k ^e . connects the chamber K ² with the channel / 1 in such a way that, provided that the g röfsere pressure in line B prevails, whereas the valve K is closed, the check valve / ^ ⁴ is -open and enters the 'pressure fluid through the chamber K ² after the pipe H and from here to the cylinder F and slept the door. The chamber K ³ stands with the channel /? ' through a bore Ar ³ · in communication, which is closed by a check valve K ^& ; the latter is given by a spring k ^! > held on its seat, the tension of which is measured in the same way as that of the spring / c ⁴ , so that this valve too is held on its seat at normal line pressure. If, however, double the pressure is put into the line, the check valve must rise, so that when the greater pressure acts on the lower end of the cylinder to close the door, the outlet fluid from the upper part of the cylinder through H ¹ in the chamber K ³ arrives, which is in communication with the outlet pipe H ^2.

From what has been said so far it can be seen that the normal position of the cock is shown in FIG. 3, ie that all channels are closed and the door is locked to prevent any movement. If you want to open or close the door, one of the handles / 'or / ^{2 must be turned} to the right or left so that the pressure fluid reaches the cylinder F and thereby opens or closes the door. When the handle is released, the cock plug is closed by the influence of springs attached to the lever I ² and the door is locked against any further movement. If, however, one wants to close all the doors at once, the higher pressure is let into the line so that the check valve K ^{1 is} opened and the liquid in the cylinder F acts on the door closing. The discharge liquid lifts the non-return valve Κ '° and then enters the exhaust pipe H ² .

If it becomes necessary to suspend the movement of one or more doors or to open one of them while it is closed by the increased pressure, so that, for example, the waitress can escape from the ship concerned, one turns one of the handles / 'or / ² in the usual direction to open the door and hold it in this position; here will be

VV ' S <

the openings in the plug / opened and the whole pressure must enter the upper end of the cylinder F and act on the door opening. During this short period of time necessary to release the operator, which is necessary due to the setting of the lever C ³ from the command bridge, a small amount of liquid passes through the valves K ⁱ , because both valves are at their upper sides during this time with the overflow pipe H ² in connection. This circumstance, however, cannot prevent that at least the usual pressure is present and causes the door to open, while the slight loss of pressure fluid is without any noteworthy damage.

When the service staff has left the department in question and you have the Has turned the handle in the appropriate direction, all pressure must be applied to the act at the lower end of the cylinder and cause the door to close.
