Description

  The present invention relates to a valve used in deep water that does not cause malfunction, and is a valve installed inside a deep water tank such as a ballast tank in shipbuilding. It relates to a valve used in deep water, which has improved accuracy and safety by recognizing the exact opening and closing of the valve outside the tank.

  Generally, in the case of a ship or the like, when it is installed in deep water like a tank or seawater in an area where a conventional valve is installed, it is difficult for humans to approach, so a remote controller is attached to the upper end of the valve. The valve is operated by hydraulic pressure. As shown in FIG. 1, the existing remote control driver system has a handle 1 and a gate valve 2 that open and close by rotating up and down while rotating, and a cylinder 3 that opens and closes vertically by removing the screw of the central axis. By adhering together, the vertical up-and-down motion system is changed to supply. However, the driving by such a change in the movement method causes considerable danger because the valve is frequently opened and closed due to the influence of foreign matter or the external influence due to the leakage of the working fluid of the driving unit.

  In addition, as a method of confirming the correct opening and closing of the valve, a method in which an electric limit switch and a potentiometer are installed and confirmed, and when the pressure of the working fluid sent to the valve driver exceeds a certain level, the valve operation is finished. This indicates that the valve position is estimated by detecting the flow rate of the working fluid and determining the ratio of the current flow rate to the total flow rate required to operate the valve driver.

  However, in the case of electric limit switches and potentiometers, the accuracy is excellent, but the safety and watertightness that can be used in deep water are reduced, and the method for checking the working fluid pressure and detecting the flow rate has improved watertightness and safety. Is excellent, but because the current position is shown differently from the actual state due to the presence of foreign matter in the valve or fluctuations in the flow rate due to changes in the ambient temperature, the accuracy is significantly reduced. Can bring about a state.

  The present invention has been made to solve the above-mentioned problems, and safety and watertightness for use in deep water are ensured, stopping due to foreign matter can be confirmed, and environmental changes such as ambient temperature can be confirmed. The object is to provide a valve used in deep water that can be handled and does not cause malfunction.

  In order to achieve the above-described object, the present invention is a valve used in deep water, in which a guide hole is formed inside from one side, and a screw portion is formed on the inner peripheral surface of the guide hole. A body part, a screw that moves along the guide hole and rotates in mesh with the screw part, a rotating part that rotates the screw, and a power part that supplies power to the rotating part to operate the rotating part And a control unit that is provided between the rotating unit and the power unit and that controls the power unit by operating a limit switch by an interlocking medium that interlocks with the screw.

  The rotating unit includes a motor that operates by receiving power from the power unit, and a bevel gear that is connected to the motor and rotates to rotate the screw.

  The control unit includes an interlocking medium interlocked with the screw and a first limit switch, receives power from the power unit and supplies the power to the rotation unit, and operates the first limit switch to supply the rotation unit. A first control member, which is a first connecting member that cuts off power supply, and a second limit switch are provided, receives power from the power unit and supplies the power to the rotating unit, and operates the second limit switch to the rotating unit. A second control member that is a second connecting member that cuts off the power supply, and the first limit switch or the second limit switch so as to supply the interrupted power to the first connecting member or the second connecting member. It is characterized by comprising a change member to be restored.

  The power unit is connected to the hydraulic pressure supply member, the hydraulic pressure supply member, a first hydraulic pressure supply pipe that supplies hydraulic pressure to the first connection member, the hydraulic pressure supply member, and the second connection member. And a second hydraulic pressure supply pipe for supplying hydraulic pressure to the pipe.

  The first connecting member or the second connecting member opens or closes a narrow pipe having a narrow flow path and a hydraulic pipe formed by a wide pipe having a wide flow path communicating with the narrow pipe and the narrow pipe. The first hydraulic pressure supply pipe or the second hydraulic pressure supply pipe is divided into two parts, and is formed to communicate with the narrow pipe and the wide pipe, respectively, and the open / close tool is a narrow pipe If the flow path is opened, the hydraulic pressure is supplied to the first hydraulic pressure supply pipe or the second hydraulic pressure supply pipe, and if the opening / closing tool closes the narrow pipe flow path, the first hydraulic pressure supply pipe or the second hydraulic pressure is supplied. The hydraulic supply to the supply pipe is cut off.

  The opening / closing tool is larger than the flow path of the narrow tube and is formed on one side of the ball and moved on the wide tube, and on the other side of the ball. It is characterized by comprising a spring formed and a plug formed at the end of the spring and operating the piston in response to the operation of the first limit switch or the second limit switch.

  As shown in FIGS. 2 to 7, in the valve used in deep water, the guide hole 110 is formed inside from one side, and the screw part 120 is formed on the inner peripheral surface of the guide hole 110. The body part 100, the screw 200 that moves along the guide hole 110 and meshes with the screw part 120, the rotating part 300 that rotates the screw 200, and the rotating part 300 that supplies power to the rotating part 300. A power unit 400 that operates the rotating unit 300, and a control that is provided between the rotating unit 300 and the power unit 400 and that controls the power unit 400 by operating a limit switch by an interlocking medium 510 that is linked to the screw 200. Part 500 and an instruction part 900 for instructing the current position according to the state of the control part 500 and the body part 100.

  Hereinafter, each configuration will be described in detail.

  The body portion 100 according to the present invention is made of a material having high strength and hardness, and is installed on the ballast, and is a portion where the valve opens and closes.

  Moreover, it is preferable to use a highly corrosion-resistant and durable material that does not corrode due to water or foreign matter and does not change in water pressure even when installed in deep water.

  The body 100 is formed with a guide hole 110 therein. Here, the guide hole 110 is a space in which the screw 200 for opening and closing the valve moves. When the screw 200 moves along the guide hole 110, the valve opens and closes.

  In particular, the guide hole 110 has a screw portion 120 formed on an inner peripheral surface thereof, and the screw 200 and the screw portion 120 are coupled to each other.

  The body 100 is generally installed vertically in deep water. Accordingly, the guide hole 110 is also formed perpendicular to the water surface.

  The screw 200 according to the present invention moves along the guide hole 110 and engages with the screw part 120 to move up and down.

  The screw 200 is connected to the rotating unit 300 and moves along the guide hole 110 in conjunction with the rotation of the rotating unit 300. When the screw 200 moves downward, the valve is closed and the screw 200 moves upward. When the valve is opened.

  Here, since the screw 200 is engaged with the screw portion 120 and rotated, there is an advantage that the screw 200 does not move freely due to water pressure or external conditions.

  The rotating part 300 according to the present invention is a member that rotates the screw 200 and is formed outside the body part 100.

  In the present invention, the rotating unit 300 uses a hydraulic motor 310 and receives power from the outside to operate.

  Preferably, the rotating unit 300 includes a motor 310 that operates by receiving power from the power unit 400 and a bevel gear 320 that is connected to the motor 310 and rotates to rotate the screw 200.

  In the embodiment of the present invention, hydraulic pressure is used as a power source, and therefore the hydraulic motor 310 is used as the motor 310.

  Since the bevel gear 320 is used, the rotational force generated from the motor 310 can be appropriately adjusted by the user.

  The power unit 400 according to the present invention is a member that provides power to the rotating unit 300, is installed on the ground, and is connected to the rotating unit 300 through a separate connecting pipe.

  In the present invention, the power unit 400 is configured to provide hydraulic pressure. On the other hand, since the power unit 400 includes a known hydraulic pump, oil tank, and the like, detailed description thereof is omitted.

  The controller 500 according to the present invention is formed between the rotating unit 300 and the power unit 400, and controls the power unit 400 by operating a limit switch by the interlocking medium 510 interlocked with the screw 200.

  Accordingly, power supplied from the power unit 400 is transmitted to the rotating unit 300 via the control unit 500, and the rotating unit 300 is regulated by the control unit 500, so that the opening and closing of the valve can be controlled. .

  That is, if the interlock medium 510 moves upward in conjunction with the screw 200 to open the valve at all, the power is shut off by touching a limit switch located above to control the power unit 400. On the other hand, even if the valve moves downward and closes the valve, the power unit 400 is controlled by cutting off the power by touching the limit switch located on the lower side.

  Here, the hydraulic pressure supplied from the power unit 400 is kept constant, but if the hydraulic pressure rises before touching the limit switch, it is sufficient to think that the screw 200 is clogged with foreign matter, and an immediate measure can be taken. It ’s fine.

  As described above, during manual operation, the hydraulic pressure of the power unit 400 does not increase above a certain pressure (40 bar), and returns to natural pressure (0 bar) when the operation of the power unit is stopped.

  If power is cut off by the operation of the limit switch in full operation, a high pressure of 80 bar or more is formed. At this time, even if the operation of the power unit 400 is stopped, the hydraulic pressure is blocked by the limit switch, so that the existing pressure is maintained without returning to the natural pressure.

  In an abnormal state such as the screw 200 being clogged with foreign matter, even if the power unit 400 is operated, only the hydraulic motor 310 rotates while the screw 200 is not operated, so that the operating load increases, and the power unit 400 During manual operation, a pressure equal to or higher than the normal state forming pressure (40 bar) is generated (40 to 80 bar), and an abnormal state can be sensed. As a reference, in the case of an abnormal state due to foreign matter, a pressure of 80 bar or higher is not generated, and if the manual operation of the power unit is stopped, the natural pressure returns to 0 bar again.

  The indicator 900 according to the present invention includes a gauge 920, a first indicator 930, and a second indicator 940. The gauge 920 has a current state corresponding to each pressure (0 to 40, 40 to 80, 80 to 120 bar). The first indicator 930 and the second indicator 940, when fully activated, operate so that a colored sphere protrudes above 80 bar, so that the valve is open or closed. Become aware of it.

It is preferably made of a second control member 530 Metropolitan consisting 914.

  Here, the interlocking medium 510 is coupled to the upper side of the screw 200 and moves in conjunction with the vertical movement of the screw 200.

  The interlocking medium 510 is formed in a rod shape and moves between the first control member 520 and the second control member 530. Therefore, the interlocking medium 510 contacts the lower surface of the first control member 520 when the screw 200 moves upward, and contacts the upper surface of the second control member 530 when moving downward. Become.

  The first control member 520 includes a first limit switch 522, receives power from the power unit 400, supplies the power to the rotating unit 300, and supplies power to the rotating unit 300 by the operation of the first limit switch 522. A first connecting member 524 for blocking, and a first change member 912 for further supplying the blocked power in the reverse direction after operating the direction changing lever 540 to change the operating direction of the valve; Consists of.

  The first connecting member 524 receives power (fluid) from the power unit 400 and transmits the power (fluid) to the hydraulic motor 310 of the rotating unit 300.

  The first limit switch 522 is coupled to the lower surface of the first connecting member 524, and prevents the first connecting member 524 from transmitting power (fluid) to the rotating unit 300 due to contact with the interlocking medium 510. Will come to let you.

  The first change member 912 restores the first limit switch 522 so that the power interrupted by the first connecting member 524 is supplied.

  The first change member 912 operates the direction change lever 540 in a state in which the first connecting member 524 cannot supply power (fluid) to the rotating unit 300 by the operation of the first limit switch 522. After that, the interrupted power is supplied again in the reverse direction.

  The second control member 530 includes a second limit switch 532, receives power from the power unit 400 and supplies the power to the rotating unit 300, and supplies power to the rotating unit 300 by operating the second limit switch 532.

  The second connection member 534 receives power (fluid) from the power unit 400 and transmits the power (fluid) to the hydraulic motor 310 of the rotating unit 300.

  The second limit switch 532 is coupled to the lower surface of the first connection member 524, and prevents the second connection member 534 from transmitting power (fluid) to the rotating unit 300 due to contact with the interlocking medium 510. Will come to let you.

  Then, the second change member 914 restores the second limit switch 532 so that the interrupted power is supplied to the second connecting member 534.

  The second change member 914 is a direction change lever in a state in which the second limit switch 532 is operated so that the first connecting member 534 cannot supply power (fluid) to the rotating unit 300. After operating 540, the interrupted power is supplied again in the reverse direction.

  The first change member 912 and the second change member 914 will be described in detail. When the valve is closed, the screw 200 is positioned on the lower side, and the second connecting member 534 is connected to the rotating unit 300. The first connecting member 524 is in a state in which power can be supplied to the rotating unit 300.

  Accordingly, power is transmitted to the first connecting member 524 and then to the hydraulic motor 310 of the rotating unit 300. Such power is blocked by the second limit switch 532 in the second connecting member 534. The second change member 914 is driven by being transmitted and circulated. In addition, when the power transmitted and circulated is transmitted to the hydraulic motor 310 of the rotating unit 300, the screw 200 is raised.

  Here, the screw 200 rises upward while rotating along the screw portion 120.

  At this time, if the screw 200 rises upward, the valve is opened, and the interlocking medium 510 interlocked therewith touches the first limit switch 522, so that the first connecting member 524 powers the rotating unit 300. Can not communicate.

  Here, when the valve is to be closed, the direction change lever 540 reverses the circulation of the power, and the power is restored by the first change member 912 so that the second connection member is restored. 534 transmits power to the rotating unit 300.

  Preferably, the power unit 400 is connected to the hydraulic pressure supply member 410, the hydraulic pressure supply member 410, the first hydraulic pressure supply pipe 420 that supplies hydraulic pressure to the first connection member 524, and the hydraulic pressure supply member 410. The second connecting member 534 preferably includes a second hydraulic pressure supply pipe 430 that supplies hydraulic pressure.

  Therefore, as described above, the hydraulic pressure supply member 410 includes a hydraulic pump, an oil tank, a pressure gauge, and the like so that the hydraulic pressure is supplied to the two first hydraulic pressure supply pipes 420 and the second hydraulic pressure supply pipe 430. To do.

  Here, the first hydraulic pressure supply pipe 420 supplies hydraulic pressure to the first connection member 524, and the second hydraulic pressure supply pipe 430 supplies hydraulic pressure to the second connection member 534.

  Preferably, the indication unit 900 includes a gauge 920 connected to the outlet of the power unit 400 and the front end of the direction change lever 540, and the first hydraulic pressure supply pipe 420 and the second hydraulic pressure supply pipe at the rear end of the direction change lever 540. It is preferable that the first indicator 930 and the second indicator 940 connected to the 430 are provided.

  At this time, the gauge 920 indicates a phrase indicating the current state of the valve by the hydraulic pressure discharged from the power unit 400, that is, a normal state from 0 to 40 bar, an abnormal state from 40 to 80 bar, and a fully operational state from 80 to 120 bar. It is preferable to have a complaint.
