Abstract

PURPOSE:To save the manpower, the time and cost with a small number of equipment and materials by installing a water adjusting valve, a water stopping valve, a float control fulcrum actuating the water stopping valve, a float actuating the float control fulcrum and a water quantity checking and monitoring water column gage. CONSTITUTION:A circulation flow apparatus 11 is connected with a micro pressure application and reduction adjusting device 10, main body, through a microbarometer 7 and an abnormality stopping valve 9. Water is supplied from a water supplying port E by opening an adjusting valve 1. When water flows in the direction of C through a water quantity regulating valve 2 and as its quantity increases, a float 6 floats up and a gaseous phase part B is pushed up and pressurized to give a micro barometric pressure to a storage tank or container through a supply and discharge pipe 16. To prevent such pressurizing force, the float 6 stops the supply of water by controlling the water quantity regulating valve with a float rod 14 through a float control fulcrum 4 and the water quantity regulating valve 2 through a control rod 13 as the amount of water increases. When reducing the pressure, water is first supplied from the water supplying port E and then from the top of the micro pressure application and reduction adjusting device 10. It is thus possible to enhance safety and to easily adjust micro pressure at the application and reduction of pressure.

Description

[Detailed description of the invention] When pressurizing or depressurizing a storage tank or container to a certain level, conventional equipment such as a manometer, a pumping device, a connecting hose, a pump that applies depressurizing or pressurizing pressure, etc. There are many people involved, and it requires a lot of manpower, time, and other expenses.

The present invention improves this point, improves safety by incorporating the necessary equipment into the device in a compact manner, and allows easy adjustment to minute pressures such as pressurization and depressurization.

Specifically, all pipes and inlets located in the storage tank or container must be otherwise sealed and the supply/discharge vibrator connected at certain points. It is connected to the micro pressure adjustment device 0 of the main body through the circulation device (2), the micro-air pressure (2), and the abnormality stop valve (2). The minute adjustment pressure adjustment device 0 opens the control valve ■ from the water supply port E and supplies water, thereby controlling the water amount limiting valve ■.
The amount of water flows in the direction of C through , and as the amount of water increases, the float (2) rises to the surface. Therefore, the gas phase part B is pushed up and pressurized, and a microvoltage force is displayed in the direction of pressurization from F through the abnormality stop valve (2) on the microair pressure gauge (2).

The circulating flow device (2) is filled with the gas phase (2), and applies micro-air pressure to the storage tank or container through the supply/discharge vibrator (@). At this time, in order to prevent the pressurizing force, as the water volume increases, the float rod [phase] controls the water volume restriction valve via the float control fulcrum ■ and the water volume limiter ■ through the control rod 0. ,
Stop water supply. Let this state be the position of the float (■) and the float control rod (■). When reducing the pressure, water is first supplied from the water supply port E, and also from the upper part of the minute pressure adjustment device 0.

At this time, the float ■ and the control rod @ are in position, and the water supply is stopped by closing the water flow restriction valve ■. In the above state, by connecting a storage tank or a container to the supply/discharge vibrator and opening the control valve 0, the minute pressure adjustment device fl(i) starts operating.

The amount of water is set by visually checking the water meter (2) and checking the minute pressure gauge (2) while adjusting the water amount until a certain pressure is reduced by adjusting the control valve 0. In this case, the gas phase section (2) of the circulation flow device (2) is visually observed if there is a possibility that fluid may flow into the storage tank or container when the pressure is reduced.

If fluid flows into the gas phase part (2), close the abnormality stop valve, re-inspect it, and return to Hatsutomo's pressure reduction method.

From the above explanation, the present invention aims to provide a device that can easily and inexpensively perform minute pressurization and depressurization by using the minute adjustment pressure "A adjustment device [phase].
