Description

  The present invention relates to a ball tap device having a ball tap that automatically opens and closes a valve by moving the float up and down.

  The ball tap is a water tap for supplying water to the water tank, and is disposed above the water surface of the water tank. The ball tap generally has a float that moves up and down in conjunction with a change in the water level in the water tank, a valve connected to the water supply pipe, and an arm that connects the float and the valve. The ball tap configured in this way opens the valve by lowering the float to supply water to the aquarium, and when the water level in the aquarium reaches a preset full water level, the valve is closed by rising the float to supply water. Stop.

  Patent Document 1 listed below describes a full / low water alarm device having a ball tap and a switch that is connected to the ball tap arm via a transmission tube and outputs a full signal based on the upward movement of the ball tap float. In this full / low water alarm device, when the water surface reaches the full water level, the arm that rises accordingly pushes up the transmission pipe, and the switch pressed by the transmission pipe is activated.

  When an abnormality occurs in the ball tap, the ball tap does not operate normally. For example, when water enters the float, the buoyancy of the float disappears, so that the float does not move up and down normally in conjunction with the fluctuation of the water level. Alternatively, when the link mechanism provided between the arm and the valve and amplifying the movement of the arm based on the vertical movement of the float is fixed by catching or the like, the float does not normally move up and down in conjunction with the water level. Alternatively, when a foreign object is caught between the valve body and the valve seat, the valve does not close normally.

  If the ball tap does not operate normally as described above, the open state of the valve is maintained, and water is supplied even if the water level in the water tank becomes full. As a result, there is a problem that water overflows from the water tank and the surroundings of the water tank are flooded. Moreover, when the water supplied to a water tank is a clean water, there exists a problem that an unnecessary water bill will be required. Moreover, when the water supplied to the water tank is clean water, there is a possibility that the water outlet space is lost and the clean water is contaminated.

  Therefore, there is an example in which a plurality of electrode rods or throat switches are arranged in the water tank, and an abnormal water level of the water tank, for example, a water level rising from the full water level is detected by these electric signals, and a water level alarm device is provided that outputs alarm information. . According to this water level alarm device, the detection of the water level that has risen above the full water level can be detected as a ball tap abnormality. However, the water level alarm device cannot be installed unless the capacity of the water tank is small and the installation space inside the tank is sufficient. Moreover, since the number of parts related to the water tank increases, there is a problem that the number of assembling steps increases.

  The objective of this invention is providing the ball tap apparatus which can detect abnormality of a ball tap with a simple structure, without providing a water level warning apparatus separately.

  The present invention includes a float that moves up and down in conjunction with a change in the water level in the aquarium, a valve connected to a pipe that supplies water to the aquarium, and an arm that connects the float and the valve. In the ball tap device having a ball tap that automatically opens and closes the valve, the ball tap abnormality is caused by the continuity between the two electrodes spaced apart on the surface of the float and the two electrodes through the water in the water tank. And at least one of the two electrodes is provided in a non-contact region that does not contact water in the water tank during normal operation of the ball tap.

  Another invention includes a float that moves up and down in conjunction with a change in the water level in the aquarium, a valve connected to a pipe that supplies water to the aquarium, and an arm that connects the float and the valve. In a ball tap device having a ball tap that automatically opens and closes a valve by the vertical movement of the ball tap, the ball tap of the ball tap is determined by the conduction state of the two electrodes provided at intervals in the water tank and the two electrodes through the water in the water tank. An abnormality detection unit for detecting an abnormality, and one of the two electrodes is a region on the surface of the float, provided in a non-contact region that does not contact the water in the water tank during normal operation of the ball tap, The other of the two electrodes is provided in the water tank so as to contact the water in the water tank during the normal operation.

  In addition, an electromagnetic valve attached to the pipe and an electromagnetic valve control unit that controls the electromagnetic valve, the electromagnetic valve control unit controls the electromagnetic valve to be closed when an abnormality is detected by the abnormality detection unit. be able to.

  In addition, it has a timer unit that counts time from when the abnormality is detected by the abnormality detection unit, and the electromagnetic valve control unit controls the electromagnetic valve to be closed when a predetermined time has elapsed. be able to.

  Moreover, it has the warning information output part which outputs warning information outside, and a warning information output part can output warning information based on the abnormality detection of an abnormality detection part.

  In addition, it has a timer unit that counts the time from when the abnormality is detected by the abnormality detection unit, and the alarm information output unit can output alarm information when the time counted by the timer unit has elapsed for a predetermined time it can.

  According to the ball tap device of the present invention, it is possible to detect an abnormality of the ball tap with a simple configuration without separately providing a water level alarm device.

It is a figure which shows the structure of the ball tap apparatus which concerns on this embodiment. It is a figure which shows the structure of the ball tap apparatus which concerns on another embodiment. It is a figure which shows the structure of the ball tap apparatus which concerns on another embodiment.

  Hereinafter, embodiments of a ball tap device according to the present invention will be described with reference to the drawings. As an example, a water receiving tank for storing clean water is cited, and a ball tap device installed in the water receiving tank will be described. Note that the present invention is not limited to a water receiving tank, and can be applied to a ball tap device installed in a toilet tank or a cooling tower water tank, for example, as long as it is a water tank that stores water.

  The ball tap device 10 has a ball tap 14 disposed above the water surface of the water tank 12. The water tank 12 has a water supply pipe 16 for supplying water from a water source, and an overblow pipe 18 for draining excess water from the water tank 12 when the water level in the water tank 12 exceeds a preset full water level. And are connected. The full water level is set with a predetermined interval on the lower side in the vertical direction with respect to the open end portion of the water supply pipe 16 in order to secure the water outlet space. And the opening of the overblow pipe 18 in the water tank 12 is provided between the open end of the water supply pipe 16 and the full water level, and the water outlet space disappears due to the rise of the water level, and the water is contaminated. To prevent. In addition, in this embodiment, although the case where the overblow pipe | tube 18 was connected to the water tank 12 was demonstrated, it is not limited to this structure, The overblow pipe | tube 18 can also be eliminated.

  The ball tap 14 is a water tap for supplying water to the water tank 12. The ball tap 14 of this embodiment may be any type of ball tap, and may be a single type, double type, or sub-valve type constant water level valve.

  The ball tap 14 includes a float 20 that moves up and down in conjunction with a change in the water level in the water tank 12, a valve 22 connected to the water supply pipe 16, and an arm 24 that connects the float 20 and the valve 22. The valve 22 is connected to the end of the water supply pipe 16. Therefore, as shown in FIG. 1, the valve 22 corresponds to the open end of the water supply pipe 16 described above.

  When the water level in the water tank 12 is lowered, the ball tap 14 configured in this manner supplies the water tank 12 with water by opening the valve 22 by rotating the arm 24 toward the broken line in FIG. On the other hand, when the water in the water tank 12 rises due to the water supply, the arm 24 is rotated by the rise of the float 20 and the opening degree of the valve 22 is reduced. When the water level as shown in FIG. 1 is reached, the valve 22 is completely closed and the water supply is stopped. As described above, the ball tap 14 automatically opens and closes the valve 22 by the upper and lower portions of the float 20 and tries to keep the water level in the water tank 12 at the full water level.

  Further, the ball tap device 10 has a control circuit 26 for controlling this device. The control circuit 26 is provided in the water tank 12, but is not limited to this configuration, and may be provided apart from the water tank 12.

  The ball tap device 10 according to the present embodiment has an abnormality in the ball tap 14 due to the conduction state of the two electrodes 28 and 30 provided on the surface of the float 20 with a space therebetween and the electrodes 28 and 30 through the water in the water tank 12. And an abnormality detection unit 32 for detection. At least one of the two electrodes 28 and 30 is provided in a non-contact region that does not come into contact with water in the water tank 12 during normal operation of the ball tap 14. The abnormality detection unit 32 is provided in the control circuit 26.

  The float 20 is connected to an arm 24 that can rotate on a plane including a vertical direction. For this reason, since the float 20 moves up and down in a predetermined path, the area of the surface of the float 20 where the float 20 and the water in the water tank 12 are in contact with each other during normal operation is limited. In the present embodiment, the electrode 28 is provided in the region, and the electrode 30 is provided in a region other than the region, that is, a non-contact region. Between these electrodes 28 and 30 and the abnormality detection unit 32, wirings through which current flows are respectively connected. The wiring is laid on the float 20 and the arm 24.

  According to this configuration, even when an abnormality occurs in the ball tap 14 and the ball tap 14 does not operate normally, the non-contact area of the float 20 is submerged, so that the two electrodes 28 and 30 are in a conductive state. Thus, the abnormality detection unit 32 can detect an abnormality of the ball tap 14.

  The ball tap device 10 includes an electromagnetic valve 34 attached to the water supply pipe 16 and an electromagnetic valve control unit 36 that controls the electromagnetic valve 34. The electromagnetic valve control unit 36 is provided in the control circuit 26 and controls the electromagnetic valve 34 to be closed when an abnormality is detected by the abnormality detection unit 32.

  By such control, even when the valve 22 is kept open due to an abnormality in the ball tap 14, the electromagnetic valve 34 is closed and water supply into the water tank 12 can be stopped. As a result, drainage from the overblow pipe 18 can be prevented, and an unnecessary bill for water supply can be prevented. Moreover, in the water tank to which the overblow pipe 18 is not connected, contamination of clean water due to the absence of the spout space can be prevented, and inundation outside the water tank can also be prevented.

  In addition, the ball tap device 10 includes a timer unit 38 that counts the time from when the abnormality is detected by the abnormality detection unit 32, and a time counted by the timer unit 38 when a predetermined time (for example, 30 seconds) has elapsed. And an alarm information output unit 40 that outputs alarm information.

  The timer unit 38 prevents erroneous detection of the abnormality detection unit 32. For example, even when the ball tap 14 is in a normal state, the electrodes 28 and 30 may be in a conductive state via water droplets in the water tank 12. In this case, the conduction state is temporary and is not maintained for the predetermined time. The timer unit 38 eliminates erroneous detection of the abnormality detection unit 32 based on such a state.

  It is preferable to add such a function of the timer unit 38 to the electromagnetic valve control unit 36 described above. That is, the electromagnetic valve control unit 36 controls the electromagnetic valve 34 to be closed when the time counted by the timer unit 38 has elapsed for a predetermined time. Thereby, it is possible to prevent the hunting operation of the electromagnetic valve 34 that the electromagnetic valve 34 is closed only during the temporary conduction state as described above.

  The alarm information output unit 40 is connected to, for example, a management room of a building where the water tank 12 is installed via a communication line, and outputs alarm information to the management room. Thereby, the manager in the management room can grasp the abnormality of the ball tap 14 and can take a quick response. The alarm information output unit 40 can also output alarm information to a remote monitoring center or a portable terminal of an administrator who manages the water tank 12.

  According to the present embodiment, the ball tap 14 has a simple configuration in which the electrodes 28 and 30 are installed on the float 20 without using a water level alarm device in which a plurality of electrode rods or throat switches are arranged in the water tank as in the prior art. Abnormalities can be detected. The ball tap device 10 can be installed even if the capacity of the water tank 12 is small and the installation space in the water tank 12 is not enough, and the assembly man-hour can be reduced as compared with the case where a water level alarm device is provided separately. it can.

  Although the case where the electrode 28 is provided in the contact area of the float 20 and the electrode 30 is provided in the non-contact area of the float 20 has been described in the present embodiment, the present invention is not limited to this configuration. As shown in FIG. 2, two electrodes 28 and 30 can be provided in the non-contact region. Even in such a configuration, the non-contact region of the float 20 is submerged due to the abnormality of the ball tap 14, so that the conductive state of the two electrodes 28 and 30 is achieved.

  In the present embodiment, the case where the electrodes 28 and 30 are provided on the float 20 has been described, but the present invention is not limited to this configuration. For example, as shown in FIG. 3, the electrode 28 can be installed in the water tank 12 and the electrode 30 can be installed in a non-contact region of the float 20. The installation location of the electrode 28 is in the water tank 12, for example, the inner wall of the water tank 12 so as to come into contact with the water in the water tank 12 during the normal operation of the ball tap 14. Even in such a configuration, the non-contact region of the float 20 is submerged due to the abnormality of the ball tap 14, so that the conductive state of the two electrodes 28 and 30 is achieved. Moreover, it is space-saving compared with the case where a water level alarm device is provided separately.
