Description

DETAILED DESCRIPTION OF THE INVENTION The field of application of -I-A-1- is related to anti-freeze plugs used to prevent freezing of water pipes in winter, and in particular, it is applicable to This invention relates to a device for controlling.

- Advantageous Technology - As mentioned in I5, in cold regions, etc., the indoor humidity at night drops to below zero, so if the water in the distribution pipe of Kara 7 that is distributed indoors condenses, the E- There is a risk that the wood will become unusable. For this reason, in cold regions, on nights when the air humidity is likely to drop below zero, prevent freezing by leaving the drain open or using an antifreeze plug built into the base of the one-minute pipe. Trees in the distribution pipe are removed to the outside.

By the way, conventional antifreeze valves used for such purposes are of the manually operated type or of the remote operated type using a seven-point controller. Therefore, in these situations, there is a tendency for people to forget to drain water from distribution pipes without realizing that the temperature is dropping, or for trenches to freeze during drilling. For this reason, conventionally, the remote control device for the antifreeze valve is equipped with a water temperature control device.

Attempts have been made to dynamically switch the antifreeze valve to the drain state when the temperature reaches the ideal freezing temperature. However, in this remote automatic control device, when the expected freezing temperature is detected by the water temperature sensor, the water in the pipe is immediately removed by 3 tons, and the water in the pipe is immediately removed. Water stops coming out when π occurs, and in such a case, it is necessary to return the unskilledness to continuous +6.
It was cumbersome to operate, and it was a hassle to wait for water to come out of the drain.

-Purpose of the invention- Is the purpose of 4.41 Akira remote and automatic control of the conventional single-stock stopper as described above? In view of the problem of usability of a C-room, an object of the present invention is to obtain a remote control device which can secure necessary water without requiring any operation when taking a bath at night.

Summary of the Structure - In order to achieve this objective, the present invention provides freezing of the water temperature sensor [! Temperature detection turns unskilled into a wooden prayer + island! ,l) A remote automatic control device for changing the kneading property is used to set the kneading property to a drained state when the expected stocking temperature continues for a period of -CllIr after the expected temperature for the kneading process is detected. This is a suggestion to switch.

- Sentence Example - Not Q'! An embodiment of It will be described in detail with reference to FIGS. 1(A) to 1(D).

Further, the one-minute pipe 3 is provided with a water temperature sensor 7 for detecting the water temperature inside the pipe, and this water temperature sensor 7 monitors the water temperature inside the pipe. Further, the distribution pipe 3 is provided with an intake valve 8 at its highest position as an intake port for draining water.

In addition, for remote operation of the unskilled unit 5, and for receiving detection signals of the water temperature sensor 7, wiring is provided between the individual operation panels 9, 9, . . . and one centralized operation 6JlO.

The individual operation panel 9 is as shown in Figure 1 CB).

In such a control panel 9, switches 12 and 13 are used for locking and locking operations, respectively.

By forming a current supply circuit to the 7-guchiyuator 4, the unskilled parts 5 are individually remotely controlled. Also, alarm moe, Kuswitch 16
is used to check the circuits of the lamp 14 and buzzer 15.

Lai, Chi 12.11, and 7777° of the individual Saehaku board are organized into a ψ row circuit, so that one water operation, water drain, and drain operation can be performed from both the centralized operation panel and the individual operation panel. At the same time, the operating instructions 6 are displayed. Buzzer 20
operates when any one of the buzzers 15 on each individual operation panel is operated! ! The circuit is configured as an operation circuit with a logical sum condition that generates a signal.

All of the clumsy remote control circuits using these operation panels, including the necessary cables, are provided in a separate operation panel 9. However, inside the actuator 4, an opening/closing position detector (for example, a limit switch) of 5 degrees is provided. The remote control circuit is composed of a microcomputer and a relay circuit depending on the scale of the water supply facility.

For example, a remote control circuit with a relay circuit configuration uses a self-holding relay or its relay circuit to operate a water flow control switch + 2

In this state, the freezing temperature is monitored for a certain period of time (for example, 60 seconds) (Step S6), and at a certain time: freezing fr 4! , While the temperature is maintained, perform the tightening and extraction operations (step S7). , During the monitoring period of the expected freezing temperature, when the canon is opened and warm water flows into the distribution pipe 3, the temperature detected by the water humidity sensor 7 will be higher than the expected freezing temperature. 1! The information is stopped 1 (step Sa), and the status returns to /s4.

The control can be made more reliable by including control in the Ah water operation and water draining operation to automatically check the operation of the antifreeze faucet using the opening/closing position detector of the antifreeze faucet.

-Effects of the Invention- As is clear from the above explanation, according to the present invention, when the expected freezing temperature lasts for a certain period of time, the unmixability is changed to 6 for the first time. You will be freed from the hassle of manually rewriting the unskilled records each time.
Even sensitive and unskilled switching operations can be performed by VA.
