Description of the Related Art Conventionally, there are three types of pressurized water supply systems for indoor fire hydrant equipment, outdoor fire hydrant equipment, and sprinkler equipment, which are based on the Fire Service Law: an elevated water tank system, a pressure water tank system, and a pump system. The elevated water tank system is a system in which a water tank is installed at a high position to obtain water pressure. The pressure water tank system is a system in which compressed air is enclosed in water in the pressure water tank by a compressor or the like to obtain water pressure. The pump system is a system in which a pump is rotated by power of an electric motor or an engine to obtain water pressure.

財のある神社仏閣に主として使用されている。Looking at the characteristics of these three methods, the elevated water tank method requires the water tank to be placed at a high position and the installation location is limited, but no power is required, and the equipment is mainly the water tank and piping, and there are few failures. It is mainly used for shrines and temples with important cultural properties because it can obtain stable water pressure.

ので、現在はほとんどこの方式は利用されていない。In the pressure water tank system, about 2/3 of the volume of the container is filled with water in the water tank of the pressure container, and the remaining volume is filled with compressed air to obtain the water pressure. An air compressor that can automatically pressurize when the pressure drops is provided, but it is not intended to compensate for the large pressure drop due to water discharge, but the pressure drop due to normal air leaks, water leaks, etc. It was a facility assuming. For this reason, the pressure in the water tank decreases with water discharge, so that the pressure of the first compressed air becomes three times or more the necessary discharge pressure.
From the above, the pressure resistance of the water tank is 3 times or more the discharge pressure, and the water tank volume is 1.5 times the required amount of water. Since the water tank becomes large and heavy, and the service pressure of connected equipment also becomes high, this method is rarely used at present.

る様義務付けされている。The pump system is a system for obtaining a water pressure by rotating the pump by using the power of an electric motor or an engine. However, if there is a power source, a pump and water, water can be continuously supplied for a long period of time. Since various water tanks made of resin, metal, concrete, etc. can be used as the water tank, most of the current facilities are of this type.
The mainstream of fire fighting equipment is a combination of an electric motor and a pump that uses electricity as a power source in this method.
In addition, since this method uses electricity, it is obliged to add equipment such as dedicated power receiving equipment and emergency power generation equipment in consideration of the influence of power failure.

していた。Considering the conventional pressurized water supply system, the elevated water tank system has few failures, but it requires a place to secure a high position, so it is excluded except for special cases such as cultural assets. Is generally difficult to use. As mentioned above, the pressure water tank system requires a water tank volume that is 1.5 times or more the required water volume.
The pressure resistance of the pressure vessel and the pressure resistance of the connected equipment were up to about three times higher than the required water discharge pressure, and it was generally difficult to use. The pump method is the most popular method at present, and because of its various advantages, it was an important method as a pressurized water supply device for fire fighting equipment and emergency water supply equipment. Therefore, it has been the mainstream of pressurized water supply equipment for emergency and fire fighting for many years.

Therefore, it cannot be used during a power outage, and an emergency power generation facility must be added. However, this emergency power generation facility also has a complicated structure and a large number of components. As a result, the failure rate becomes high, so sufficient inspection is required, and the inspection technique is also required to be sophisticated. Even during the unfortunate event of the Great Hanshin Earthquake in 1995, there was a report that this power supply was damaged and could not be used because there was no cooling water for the emergency power supply when switching to the emergency power supply due to a power outage.

The damage to people's lives and property due to the fire is expected to be enormous.

無くして目的を達成している。In order to effectively perform the function in the case of a fire, it is said that there are very few malfunctions due to power outages during an earthquake or disaster, and malfunctions due to malfunctions such as when using a rotating machine with many malfunctions. The purpose is achieved from that. In order to prevent damage to humans and animals and plants, there is no rotating machine, there is no injury by touching rotating parts, and high-pressure gas that is an energy source is inert such as nitrogen, carbon dioxide, helium-argon, etc. Although the purpose is almost achieved by using gas or air, the gas used is sent at the same time as the end of the water supply, and choking due to this gas is also considered. Therefore, in the present invention, just before the end of the water supply, the main water supply pipe is used. By adding a device that closes the main pipe with the shut-off valve provided at the end, the danger to the human body is eliminated and the purpose is achieved.

を有効に利用できる。The problem that the installation is simple, the installation place is not limited, and the installation area is small is different from the conventional water tank, that is, the effective water amount can be almost the same as the water tank volume. The aquarium becomes smaller. Also, since a sturdy pressure water tank is used, it can be stored indoors, outdoors, under the floor,
It is assumed that it will be buried in the ground and various installation places, and by making each device a unit type that is directly fixed to the pressure water tank or burying the pressure water tank, the installation area can be reduced and the installation space can be effectively used. .

する事で目的を達成できる。For the problem of being able to cope with various fire protection objects such as low flow rate to high flow rate and low water pressure to high water pressure, the gas circuit pipes and equipment must be installed so that a large flow rate can be flown. Thick, large capacity, high pressure compressed gas, large instantaneous flow rate,
Etc. achieved the purpose. A low water pressure to a high water pressure load can be easily handled by the present invention, and each head load can be handled only by adjusting the set pressure of the pressure regulator. The conventional pump cannot change the pumping height, and it has to be replaced. For that reason, the electric equipment must be changed, which requires a great deal of labor and money. However, the change in the lifting height occurs after the installation, such as building expansion. In the device of the present invention, when the head changes, the setting value of the pressure regulator is only reset, but if there is a shortage of gas with it, the purpose can be achieved by adding gas. .

あった。To solve the problems that the difference between the hydrostatic pressure and the water pressure at the rated flow rate is not large, and that the change in the water pressure due to the change in the flow rate is small, piping or pipes are used to reduce the pressure loss in the gas passage. Make the device thicker. The purpose was achieved by using a pressure regulator with a large capacity and a small pressure loss. FIG. 17 is a performance test table of a gas pressure type pressurized water supply apparatus with an effective water amount of 6000 l in the present invention. As can be seen from the figure, the difference between the hydrostatic pressure and the constant flow rate is 1.5 Kgf / cm.
Less in about 2, but for conventional pressure water tank system, to this difference becomes 12 kgf / cm 2 or more, was difficult to use.

めにある。In order to deal with vibrations such as earthquakes and malfunctions due to external pressure, a pressure vessel is used for the water tank. Therefore, the pressure tank is strong against internal pressure and external pressure. By using a unit system in which each device is attached, the device itself is resistant to vibration. But,
If the piping inside the building is damaged, water will be discharged unnecessarily, so a device for opening the main water pipe only after receiving a start signal from the outside is also added. That is why the combination of the shut-off valve (13) and the activation signal (26) of FIG.

Therefore, in order to prevent the gas from being released, various considerations have been made, such as making the piping of the gas circuit a welded joint as much as possible and adopting durable parts. However, if the air still leaks, the pressure gauge with lower limit contact (6) gives an alarm as shown in FIG.

However, since it cannot be said that there is no effect of air leaks, the following equipment is added to the pressurized water supply system of the fire fighting facility, which is an emergency, as shown in Fig. 7, and The water supply system is not affected.
Explaining briefly in FIG. 7, the high-pressure gas container connected to the collecting pipe is shut off by the container valve for all containers except the pilot cylinder (1A), and is not ventilated with the collecting pipe. Air leaks from these containers are rare. Normally, a pilot cylinder (1A) is passed through the gas pipe path to fill the pressure water tank (8) with gas. In this way, the equipment is always ready to send water, but in the event of air leaks, an alarm is issued when the pressure gauge with contacts (7A) is detected. In the case of water supply by the start of water discharge, a pressure gauge with contacts (7
The electromagnetic valve unit (2A) is activated by the signal of the detection of the contact on the low pressure side of (A), gas is sent to the circuit of the container valve opener (3A), and all container valves are opened. Considering the malfunction due to the failure of the electric circuit of this solenoid valve, if the pressure applied to the valve chamber of this solenoid valve becomes less than a certain pressure, use the force of the spring to The valve opening circuit is vented to open all container valves. With this double opening system, the container valve can be surely opened when necessary. The operation of the solenoid valve unit (2A) will be described with reference to FIGS. In the figure, the vent (37), the vent (3
8) is connected to the collecting pipe. The vent (39) connects to the container valve opener. When the pressure in the collecting pipe is high, the valve chamber (3
The pressure in 3) is also high, pushing the valve stem (34) to the right and closing the passage of the vent (39). FIG. 18 shows the state. When the coil (31) of the solenoid valve is energized, the valve stem moves to the left, the passages of the vent (38) and the vent (39) are opened, pressure is applied to the container valve opener, and the container is opened. Open the valve. Even if the coil (31) is not energized due to a failure of the electric circuit, if the pressure in the valve chamber falls below the force of the spring (35), the valve stem moves to the left,
The vent (38) and vent (39) are opened to open the container valve. FIG. 19 shows the state.

To the collecting pipe (2). Since the gas of the other containers except the pilot cylinder (1A) is closed in the path by the container valve, the collecting pipe is filled only with the gas of the pilot cylinder (1A).
This high-pressure gas passes through the sluice valve (4) and then the pressure regulator (3).
But is reduced to the working pressure here, and is introduced into the pressure water tank (8) through the sluice valve (5) and the pipe (7).

In order to prevent wasteful water discharge due to breakage of the external pipe, in this figure, the shutoff valve is automatically opened when the external start signal (26) is received, and the main water pipe is shut off at other times. When the start signal is received and the solenoid valve (20) energized by the control panel is actuated, the shut-off valve (13) is opened by letting the shut-off valve vent gas. Since the main valve (12) is always open, the shutoff valve (13) is opened and water is supplied.

【００３２】動力としての電気設備が不要なので専用受
電設備や非常用発電設備も不要である。Since electric equipment for power is not required, neither dedicated power receiving equipment nor emergency power generating equipment is required.
【００３３】送水圧力を圧力調整器の調整により自由に
変える事ができる。流量も広範囲に対応できる。The water supply pressure can be freely changed by adjusting the pressure regulator. It can handle a wide range of flow rates.
【００３４】静止機器であるために故障が少なく、送水
圧力の変化少なく、放水時の水の状態も脈流することが
ない。Since it is a stationary device, there are few failures, the change in water supply pressure is small, and the state of water at the time of water discharge does not pulsate.
【００３５】ガスの圧力にて送水するので、ポンプ方式
の様に呼水の必要がなく、呼水不能などによる送水不能
も無く信頼性が高い。Since water is sent at the pressure of gas, there is no need for priming as in the pump system, and there is no water supply failure due to irrigation failure or the like, and reliability is high.
【００３６】圧力水槽とガスの容器や、他の機器を一体
化する事が出来るので、地震の振動に対しても強い装置
となる。Since the pressure water tank, the gas container, and other devices can be integrated, the device is strong against earthquake vibration.
【００３７】装置を一体化する事により、装置がコンパ
クトになり、床下にも収納する事が出来るので設置面積
が少なくて済み、設置場所もすっきりする。By integrating the device, the device becomes compact and can be stored under the floor so that the installation area is small and the installation place is neat.
【００３８】窒素ガス等の不活性ガスを使用する事によ
り水槽内の水の腐敗やタンク、配管等の腐食もほとんど
無いので非常用飲料水貯蔵や送水の装置にもなる。By using an inert gas such as nitrogen gas, there is almost no decay of water in the water tank or corrosion of the tank, piping, etc., so that it can also be used as an emergency drinking water storage or water supply device.
【００３９】圧力水槽を単体に埋設して、装置を構成す
ることもできるので、場所が狭くても良い。又、美観を
損なう事も無い。Since the apparatus can be constructed by embedding the pressure water tank in a single body, the space may be small. Also, it does not spoil the aesthetics.
