ている。Conventionally, in this type of pressure vessel, a deformable bag-shaped bladder made of flexible elastic material is attached to the main body of a rigid airtight structure, and gas is sealed between the main body and the bladder. The water pumped up by operating the pump is stored in the bladder inside the container body installed at the top of the building, and the water is stored in the bladder directly above the pump at the bottom.
A pressure switch installed inside the pipe detects the internal pressure of the pipe and stops the water pump, allowing the water stored in the bladder to be released!
! A system is disclosed in which water is supplied to various faucets inside a product.

タハンマ防止器を設置しなければならない。In the conventional example, in the process of pumping water with a water pump, a large amount of air flows inside the pumping pipes, and the water that floods with this air is directly stored in the 7 ladder inside the main body installed at the top. , air gradually enters the bladder during long-term operation.
This stagnant air is trapped in the bladder because there is no escape route.
The volume of water stored in the bladder is reduced. As a result, the water pressure in the piping pumped by the lift pump reaches the current pressure, and the pump operation stops Fq.The amount of water accommodated in the bladder in the container is smaller than the initial planned water volume, and the lift pump resumes normal operation. 11 If the water is damaged, regular water supply will not be provided. In addition, since the pump operation is controlled by detecting the pressure inside the piping at the top of the building, the pressure when the pump starts and stops! The pressure switch is likely to malfunction due to the i-motion, and the operation υ control of the water supply pump system will not be performed normally. A large container water hammer preventer must be installed directly above this pump.

応した運転を行うことができず、このため圧力容器各部
ヤ給水圧に異常現象の状態で運転３行うことがあり。In addition, since the pressure inside the water supply pipe is detected at the bottom of the building, for example, even if the upper and lower limits of the pressure vessel installed at the top are set to the upper limit L5 kg/cm and the lower limit 1 to 9/Cl11, the lower limit of the building The set pressure at the pressure switch must be determined by taking into account the water head pressure from the pressure vessel to the pressure switch and the pressure loss flowing through the pumping piping. However, it is impossible to accurately calculate the pressure loss flowing through the piping depending on the building and piping conditions, and it is not possible to operate the pressure vessel in accordance with the current pressure. Operation 3 may be performed under the condition of the phenomenon.

圧力容器や給水栓器具の寿命低下又は給水圧過不足等の
問題を生じることがある。Problems such as a shortened lifespan of pressure vessels and hydrant equipment or excess or insufficient water supply pressure may occur.

実な配管内の空気放出を行うことが困難で満足な性能を
得ることはできない。In order to solve the above problem, it may be considered to install a pressure switch and an air vent valve directly on the piping section at the top of the building, but buildings and piping conditions vary, and piping connection work after installing the pressure vessel must be done at 8 o'clock. Therefore, the positional relationship with the pressure vessel is not constant, and it is difficult to detect pressure according to the water supply system and reliably release air from inside the piping, making it impossible to obtain satisfactory performance.

２Ｉｌ盤に信号を送り異常を知らせることができる。The water stored in the water tank 21 is sent to the pump 2 via the piping 21.
Water is pumped up by 2. Due to the stirring by the pump 22, air is mixed in and flows into the delayed flow section I of the pressure vessel through the pumping pipe 2G. Since the volume within the delayed flow velocity section 7 is formed to be sufficiently larger than the inner diameter of the pumping pipe 26, the flow rate of the water in the pumping pipe 26 sent by the pump 22 becomes faster and faster (normally, this delayed flow velocity section The flow rate of water is 0.
It is designed to be 2 m/s or less. ) The water containing a large amount of air F-1 is separated into the upper part of the retarded flow rate section 7 where only the air remains and the accumulated air is discharged to the outside from the automatic air vent valve 10. Therefore, only water that does not contain air is stored in the bladder 2 of the container (tl).The initial rapid exhaust valve 11 is set in the piping when pumping is started for the first time to the pumping pipe 26 after pump installation Pf. It is used to quickly remove air in a short period of time to prevent the air from flowing into the bladder of the container body 1 many times, and is used in a closed state after all the air in the piping during the ?++] period has been released. In addition, the pressure inside the pipe is detected during this delayed flow rate portion, and the pump 22 is started (the operating pressure switch 9c sends a stop signal to the control panel, and the pump continues to run if the operating pressure switch 9C fails). is equipped with a pressure switch 9b for detecting abnormally high pressure that operates when the pressure inside the piping becomes abnormally high, and a pressure switch OaS for detecting abnormally low pressure that operates when the pump does not start and the pressure inside the piping becomes abnormally low. In addition, the safety valve 18 is provided on the side of the container body 1 to release the pressure to the outside when the abnormally high pressure detection switch 9b fails and the pressure inside the pipe becomes abnormally high. The bladder position and buttocks sensing device 13 works to detect abnormal water reception in the bladder and send a signal to the control panel 2I1 to notify of the abnormality.

水、防凍等の保４が容易に行え保守管理が３易である。In this way, by integrally providing the retarded flow section 7 in the pressure vessel main body 1, and installing various valves and pressure detection means in this retarded flow section 1, it is possible to absorb the sleeping water hammer effect of the pumping pipe 26, and to It is possible to separate and release the air in the pipes and accurately detect pressure fluctuations in a stable state without pressure fluctuations, making it the first in history.
Since the force detection device is a unit that detects near the pressure vessel body 1, it is not necessary to measure the pressure loss flowing in the pumping pipe and the difference in water head from the pump to the pressure vessel. The water supply operation reaches the design pressure (1).Also, since the various regulators are unitized, maintenance such as waterproofing and anti-freezing can be easily carried out, and maintenance management is easy.

This also solves problems such as problems that may occur when the valve is opened, etc.

行うことができるものである。As explained above, the water supply device of the present invention is used as a water supply device for islands such as buildings, and there is no abnormal pressure change such as water connection, and it solves the problem of water supply being impossible by preserving air in the pressure vessel. Since it can operate correctly according to the set pressure of the pressure vessel, it does not cause problems such as damage to the bladder inside the pressure vessel or abnormal water supply pressure, and maintains the long life of bomber switches. This allows for proper water supply operation over a long period of time.
