Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressure accumulator type pressure vessel used for water supply facilities such as buildings and condominiums.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, there is known a pressure accumulating type pressure container in which a deformable bag is installed in a rigid container in order to obtain water supply pressure.

In this type of accumulator pressure vessel, a deformable bag is initially installed in a rigid container so that water or other fluid to be fed can flow into and out of the space between the container and the bag. However, since the fluid is in direct contact with the inner wall of the container (Japanese Patent Application Laid-Open No. 50-21318), it has been pointed out that the container must be made of expensive stainless steel or the like.

As a solution to such a problem, there has been proposed a pressure container in which a fluid is allowed to flow into and out of a bag body installed in the container so that the fluid does not come into direct contact with the inner wall of the container. It has reached (June 1-37281).

[0005]

[Problems to be solved by the device]

 As described above, the pressure-accumulation type pressure vessel in which the fluid is allowed to flow in and out of the bag body has been recognized as a temporary result in that the fluid does not directly contact the inner wall of the vessel. However, in order to prevent excessive force from being locally applied to the bag according to the inflow and outflow of the fluid, the bag is deformed from an enormous state to a folded state in an orderly manner or from a folded state to an enormous state in an orderly manner. Since the bag had to be deformed, the bag had to be worked in various ways, resulting in a complicated structure.

Further, when the bag body is worn by sliding on the inner wall of the container or when the high-pressure air injected between the bag body and the container wall escapes, the bag body is hung by the fluid pressure. It was thought that it might be damaged by being pressed against.

[0007]

[Means for solving the problem]

 The present invention has been made in view of the above problems, and an object thereof is to provide a pressure accumulating pressure vessel that is structurally simple and does not cause wear or damage to the bag body. Further, the present invention further aims at providing a pressure accumulating pressure vessel in which fluid does not come into direct contact with the inner wall of the vessel.

The pressure accumulating pressure vessel of the present invention which achieves the above-mentioned object is a pressure accumulating type pressure vessel in which a deformable bag is installed in a rigid vessel, and the vessel penetrates a side wall and has an exhaust pipe. It is installed and the inner wall is covered with a lining bag, and the bag is installed inside the lining bag, and an air injection pipe that penetrates through the lid of the opening of the container is installed. The system piping connected to the bag body and connected to the lid is communicated with the space between the bag body and the lining bag body.

[0009]

[Action]

 According to the accumulator pressure vessel of the present invention, since the bag body does not require complicated work, the structure can be simplified. Further, since the bag body is not configured to be deformed between the expanded state and the folded state according to the inflow and outflow of the fluid, it is possible to eliminate the wear due to the inflow and outflow of the fluid.

Further, since the fluid flows into and out of the space between the bag body and the lining bag body, it is possible to prevent the fluid from directly contacting the inner wall of the container.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical cross-sectional view of a pressure accumulating pressure vessel according to an embodiment, in which an exhaust pipe 2 is installed on a side wall of a cylindrical (both ends closed) rigid vessel 1 placed horizontally, and a lower one side An opening 3 is provided, and a connecting flange 5 is installed in the opening 3 via a conduit 4. Inside the rigid container 1, a lining bag 6 made of a rubber sheet or other elastic airtight sheet material and having a similar shape to the rigid container 1 is attached.

Inside the bag body 6 for lining covering the inner wall of the rigid container 1, a bag body 7 made of a non-elastic airtight sheet material such as a cloth-attached sheet is installed, and the bag body 7 is It is connected to a flexible air injection pipe 12 which is introduced by penetrating a lid 11 attached to the connection flange 5 with a bolt 9 and a nut 10. A system pipe 13 is connected to the lid 11, and the system pipe 13 communicates with a space 14 between the lining bag body 6 and the bag body 7. In the figure, 15, 16 and 17 are valves, and 18 is a support leg.

After the lining bag body 6 is installed in the rigid container 1, the air between the rigid container 1 and the lining bag body 6 is evacuated through the exhaust pipe 2 while being evacuated into the lining bag body 6. The lining bag 6 is attached to the inner wall of the rigid container 1 by injecting pressurized air (for example, through the system pipe 13), and is provided to the exhaust pipe 2 after the vacuum exhaust is completed. The valve 15 is closed and the stuck state is fixed.

Further, the bag body 7 has a volume calculated in advance, and after being installed in the rigid container 1, pressurized air having a pressure calculated in advance is injected through the air injection pipe 12 to form a valve. Make sure to close 16.

According to the pressure accumulating pressure vessel of the above-described embodiment, the fluid (eg, water) is introduced into the space 14 between the lining bag body 6 and the bag body 7 through the system pipe 13 and injected into the bag body 7. The compression reaction force of the pressurized air can be used to store pressure, and the pressurized fluid can be supplied to a desired location via the system pipe 13.

When the fluid flows in and out of the space 14, the bag body 7 is not deformed to a folded state, and is maintained in a substantially expanded state by pressurized air. No work is required and the complexity of the structure can be avoided. In addition, there is no wear due to sliding contact with other members, and the life can be kept long.

Since the lining bag body 6 does not deform at all during use of the pressure container and remains attached to the inner wall of the rigid container 1, there is no possibility of wear or damage. Since this lining bag 6 can be easily installed by mounting it in the rigid container 1 through the opening 3 and then evacuating and introducing pressurized air, even if replacement is required, it can be performed easily and in a short time. it can.

Since the inner wall of the rigid container 1 is covered with the lining bag 6, the fluid flowing in and out through the system pipe 13 does not come into direct contact with the inner wall of the rigid container 1, and rust and other It is possible to prevent the above impurities from being mixed into the fluid.

[0020]

[Effect of the device]

 As described above, according to the present invention, there is an effect that it is possible to provide a pressure accumulator type pressure vessel having a simple structure and in which the bag body installed in the vessel is not worn or damaged.

Further, there is an effect that it is possible to provide a pressure accumulating pressure vessel in which the fluid does not come into direct contact with the inner wall of the vessel and therefore impurities are not mixed.
