Abstract

PURPOSE:To let water out of a water pipe by providing a valve operated by stopping and supplying pressure water, which can freely open and close an air hole disposed on a main body of a water stop piece. CONSTITUTION:An air hole 9 connected to a discharge port 3' is disposed on a main body 8 of a stop piece 7. The lower end of the air hole is freely opened and closed by up-and-down motion of a ball valve 12 loosely disposed in a valve chest 11 at the central portion of a seal body 10. The valve chest 11 is connected to the water supply port 3'' side by a hole 13 on the water pipe 4 side. The ball valve 12 is moved up and down by supplying and stopping pressure water in a water supply port 3' to open and close the air hole 9. On stopping a water path on water supply side, the valve 12 is dropped by its dead load, so that the air hole 9 is opened to discharge water in the water pipe to the outside.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the prevention of freezing of water pipes in cold regions.

(Prior art and its problems) Freezing of water pipes mainly occurs in water pipes extending from water dispensers, but conventional methods for preventing this kind of freezing include wrapping the pipes with insulation material or constantly running a small amount of water. In addition, an antifreeze valve consisting of a three-way cock is placed near the water dispenser, and water in the water pipe at the tip of the water pipe is drained from the antifreeze valve during periods when the water dispenser is not in use, thereby preventing freezing.

However, the method of wrapping insulation material has disadvantages such as difficulty in construction in narrow spaces and insufficient insulation effect in extremely cold seasons, and continuous flow of small amounts of water may cause problems of water shortage. There are disadvantages such as higher water charges and higher water charges.

Furthermore, is there a way to install antifreeze valves on each water supply valve (faucet) piped indoors and outdoors? Drain all the water (water in the water pipe between the antifreeze valve and the faucet is drained outside from the antifreeze valve's drain port)
However, since the work is done in cold weather, it is difficult and often forgotten, and when starting water supply by operating the antifreeze valve, it is inconvenient as it requires work such as closing all faucets. there were.

At present, the above-mentioned measures are used in combination to prevent freezing, but in any case, no fundamental solution has been reached.

(Means for solving the problem) The present invention has been researched to solve the above-mentioned drawbacks and inconveniences, and is capable of automatically draining water from water pipes by operating only the antifreeze valve (manually or automatically). By making it possible to prevent freezing, the aim is to use common water economically and contribute to resolving water shortages in the winter.

To further explain the invention by means of an illustrated embodiment, the water meter (
1) In a water supply system (6) with a three-way stopcock (5) installed on the nearby water pipe (4), the tap for drinking water (7) at the tap (3) must be connected to the tap for drinking water. 81 has an outlet (
An air hole (9) with a T-shaped or L-shaped cross section that leads to The valve chamber Uυ is connected to the water supply port +31'' side through the water pipe (4) side pressure hole 0'5, and the goal valve f121 moves up and down when the pressure water in the water supply port (31' is supplied or stopped). Open and close the upper air hole (9).

Another example of the second cause is the outlet diagram of the water tap t31 (31...) and the side wall between the water inlet (31') (air hole (9) in 141).
The water supply port (3S' side) of this air hole (9) can be opened and closed by a valve αS that moves up and down when pressurized water is supplied or stopped.

Furthermore, the air hole (9) may be placed in a position other than the above, for example, as in the fourth factor.
&C Water faucet (3) side L3 (// may be provided at 5).

In summary, the air hole (9) may be opened and closed as long as it can be opened and closed by a valve that moves up and down when the supply of pressurized water in the water pipe is stopped.

In the second invention, it is possible to prevent freezing by simply replacing the built-in water tap without replacing the conventional water faucet, and as shown in Figure 3, the water tap (7) X K f81 has 9 outlets for the water supply faucet (3) (provide an air hole (9) with a T-shaped or L-shaped cross section that leads to 3A,
The lower end of the air hole (9) can be opened and closed by vertical movement of a mail valve α2 loosely installed in the valve chamber 1111 in the center of the seal body (10), and the valve chamber B is connected to the hole (13) opening downward. It is something that

(Function) The present invention is embodied as described above, and can be used in a water supply device equipped with a conventional antifreeze valve by simply replacing the water supply valve or water outlet of the present invention. In other words, antifreeze plug (
5) manually to stop the water supply side water supply and stop the supply of pressurized water to the hydrant (3), and at the same time, the drain port f5f of the antifreeze valve (5) is opened and the water is removed from the hydrant (3) side. Water pipe 14+ +
The pressure inside 21 becomes zero and valve i12 or (151) falls due to its own weight, opening the air hole (9) and opening the water supply port +3f'.
<When the water pipes are connected, air enters the water pipes from the outside, and the water in the water pipes is rapidly discharged to the outside through the antifreeze valve's drain port (S).

In addition, when the antifreeze valve (51) is pressurized so that it can be operated automatically, a temperature sensor ae is built in at one or more locations in the water pipe on the tip side of the antifreeze valve (5) that are likely to freeze, as shown in Figure 4. ,
Using the electrical signal from this temperature sensor r1e, the operating source such as a motor or solenoid is operated to electrically operate the antifreeze valve (51) to close the water faucet (3) side and close the antifreeze valve (5). If the temperature sensor q detects the antifreeze temperature at the same time that the drain outlet (5F is set to open), or if the electrical connection is canceled due to a power outage, release butane, etc., open the antifreeze valve (
5) is set to be automatically operated to open the water tap (3) side 1/c by a spring or the like (not shown).

By doing this, the water in the water pipes is close to freezing temperature (
When this happens, the antifreeze valve (5) is closed by the temperature sensor σe, the drain port (5a) is opened, and the water in the water pipes is quickly and automatically drained to the outside.

Even when the antifreeze valve (5) is automatically operated, it is desirable to be able to manually operate the antifreeze valve in case of a power outage or the like.

Also: When used with a gaylor or water heater A81 as shown in Figure A5, the water supply side water pipe TI9 has a faucet with the present invention applied to the tip (3) or a Sansui m-koma (7).
An antifreeze plug (5) and a chatki valve 4 are installed on the water heater q8, which allows water to flow only once in one direction, and an antifreeze plug (51) is installed on the water supply pipe Cυ on the other hand.

Connect the water pipe (11) on the 51 side, and then install a temperature sensor (
It can also be used in a boiler device by incorporating a temperature sensor 161 and making it possible to automatically operate these antifreeze valves +511511 based on the signal from this temperature sensor +1E9.

In the diagram, the symbol is the control box, and the symbol is the electric wire.

(Effects) As described above, in the first invention, the water faucet is provided with an air hole that communicates with the outside air and the water supply port, and the air hole can be automatically opened and closed by a valve that is operated by stopping pressurized water and supplying water. Therefore, water can be automatically drained from the water pipes by simply operating the anti-freeze valve used in conjunction with this water cooling system, and by using the temperature sensor and automatic anti-freeze valve operation mechanism, there is no need for any human intervention. It can be used to prevent freezing, and can also be used in equipment such as boilers, and has a wide range of uses.

In addition, in the second invention, the freezing prevention operation is facilitated by replacing only the conventional water stopper, and anyone can easily use the conventional facility by turning it on as is.
