Abstract

PROBLEM TO BE SOLVED: To allow water to flow out from a broken water tank only by forming a diaphragm chamber on a connecting pipe, connecting one water tank to one of two chambers partitioned by a diaphragm in the diaphragm chamber, and connecting another tank to the other chamber, and operating the diaphragm with the differential pressure applied back and forth. SOLUTION: Water tanks A, B are connected each other by a connecting pipe 1. A diaphragm chamber 10 is fitted in the middle of the connecting pipe 1, and a diaphragm 11 is assembled to partition the chamber 10 into two. A water passing port 12 is provided on the diaphragm 11, and stop valves 13 are fitted on both sides of the center. When a differential pressure occurs between an inlet 14 side and an inlet 15 side, the diaphragm 11 is operated to the low-pressure side, and the inlet is closed by the stop valve 13. A valve rod 16 is fitted to the chamber 10, the valve rod 16 is manually operated from the outside of the chamber 10 to forcefully displace the diaphragm 11 to the inlet 14 side, and the inlet 14 can be closed by the stop valve 13. The water in the water tank A does not flow out to the water tank B side. There is no anxiety about drinking water in emergency, and the facility cost is not so high.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water tank system for securing drinking water for emergency measures such as an earthquake.

[0002]

2. Description of the Related Art In order to secure drinking water in an emergency,
In many cases, a water tank is installed. This water tank may be a single tank, or a plurality of tanks may be installed in one place.
Of these, in the case of multiple installations, there are many examples in which a plurality of water tanks are connected by connecting pipes. FIG. 4 shows that the water tank equipment is composed of an A water tank and a B water tank, and the A water tank and the B water tank are connected by the connecting pipe 1,
This is an example in which a water supply pipe 2 with a shutoff valve 3 is connected to the A water tank side.
FIG. 5 shows an example in which the inside of the water tank 4 is divided into an A water tank and a B water tank by a wall 5 and a communication pipe 6 is attached.

[0003]

In the case of the water tank equipment shown in FIGS. 4 and 5, for example, if the water tank B is damaged 7 due to an earthquake or the like and water flows out from the inside, not only the water in the water tank B but also However, there is a disadvantage that the water in the water tank A also flows out via the connecting pipe 1 or the communicating pipe 6. The present invention has been proposed in view of the above point, and an object of the present invention is to provide a water tank facility for securing drinking water for emergencies, in a case where a plurality of water tanks are connected by a connecting pipe, the tank is damaged. The purpose is to prevent water from flowing out only from the aquarium and not from the other aquarium.

[0004]

In order to achieve the above object, the present invention provides an aquarium facility for securing drinking water for emergencies having the following structure. 1. In a facility for connecting a plurality of water tanks with a connecting pipe to secure emergency drinking water in the water tank, a diaphragm chamber is formed in a part of the connecting pipe, and two chambers partitioned by a diaphragm in the diaphragm chamber are provided. One of the connecting pipes of the water tank is connected to one of them, and the connecting pipe of another water tank is connected to the other, and the diaphragm operates to close the inlet of the connecting pipe due to the differential pressure acting before and after the diaphragm in the diaphragm chamber. Aquarium equipment characterized by being freely configured.

[0005] 2. 2. The water tank facility according to claim 1, wherein a valve stem is mounted toward the inside of the diaphragm chamber, and the diaphragm is forcibly displaced to one side by the valve stem so as to close an inlet of one of the connecting pipes.

[0006]

[Effect] Water supply in an emergency is performed from one of the water tanks via a water supply pipe. At this time, since the entire water tank is connected by the connecting pipe, the water level falls at the same level. Further, when one of the water tanks is damaged and water flows out, the water pressure in the water tank in which the damage has occurred rapidly decreases.

As a result, the diaphragm in the diaphragm chamber attached to the connecting pipe is displaced to the inlet side of the connecting pipe on the side where the water pressure is reduced, and this inlet is closed, and the water tank is broken from the normal water tank without damage. Block the flow of water to the side. By this action, even if the inside of the damaged tank becomes empty,
Drinking water in the remaining aquarium is secured safely. When cleaning the inside of the water tank, the diaphragm is forcibly displaced to the inlet side of one of the connecting pipes by operating the valve rod to close the tank.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A water tank to which the present invention is applied is a case where two or more facilities are connected in series by a connecting pipe. In the diaphragm chamber attached to the connecting pipe, a diaphragm with a water inlet is incorporated so as to divide the inside into two parts, and stop valves are mounted on both sides in the center of the diaphragm. Connecting pipes are respectively connected to both of the diaphragm chambers, and their inlets face the stop valves of the diaphragm. The diaphragm is displaced by the differential pressure, and its stop valve is in contact with the inlet of the connecting pipe and can be closed. During normal water supply, water is supplied through the water inlet of the diaphragm.

As described above, the elastic force of the diaphragm is set so as not to be displaced during normal water flow, and to be activated only when a large pressure difference such as breakage of the water tank occurs. A valve stem is used to prevent water from flowing in from another tank when cleaning one tank.
The diaphragm is forcibly displaced to the inlet side of one of the connecting pipes, the inlet is closed by a valve rod, and water is shut off.

[0010]

FIG. 1 shows an embodiment in which the present invention is applied to two water tank facilities. The water tank comprises an A water tank and a B water tank, and the A water tank and the B water tank are connected by a connecting pipe 1. . Reference numeral 10 denotes a diaphragm chamber installed in the middle of the connecting pipe 1, reference numeral 11 denotes a diaphragm incorporated so as to divide the inside of the diaphragm chamber 10, and reference numeral 12 denotes a water inlet provided in the diaphragm 11.
3 is a stop valve attached to both sides of the center of the diaphragm 11.

Reference numeral 14 denotes an inlet on the side where the connecting pipe 1a is connected to the diaphragm chamber 10 from the side of the tank A, 15 denotes an inlet on the side where the connecting pipe 1b is connected from the side of the tank B, and the diaphragm 11 The stop valve 13 closes the inlet 14 or 15 by operating to the lower side by the pressure difference between the inlet side and the inlet 15 side. 16 is the diaphragm chamber 1 via the entrance 15 side
The valve stem 16 can be manually operated from outside the diaphragm chamber 10 to forcibly displace the diaphragm 11 toward the inlet 14 and close the inlet 14 with the stop valve 13. it can.

FIG. 2 shows that damage occurs on the side of the water tank B,
FIG. 3 is an explanatory view showing a state in which the diaphragm 11 is actuated by the differential pressure and the stop valve 13 closes the inlet 15 so that water in the water tank A does not flow out to the water tank B. FIG. It is explanatory drawing which shows the state which drained the water in the B water tank side by closing the inlet 14, and made cleaning possible.

[0013]

As described above, according to the present invention, the diaphragm chamber is attached to the connecting pipe connecting the water tanks, and the inside of the connecting pipe is shut off by a differential pressure. As a result, there is no fear that all emergency drinking water will be emptied due to damage to one of the aquariums. In addition, the present invention employs a diaphragm system that automatically operates when a differential pressure is sensed and shuts off the connecting pipe, so that there is an advantage that a power source or the like is unnecessary, maintenance is easy, and equipment costs are not so high.
