Abstract

PURPOSE:To simplify a device by arranging a rotor, connected to a float arm, in a liquid level control valve main unit of cylindrical shape connected to a liquid inlet with a liquid outlet opened and opening and closing an outlet opening by a rotary surface in accordance with a float lift. CONSTITUTION:A water tank fixes to its upper part outer wall a liquid level control valve main unit 1 of cylindrical shape or the like through a liquid inlet 2, and rotor 7, having a rotary surface 8 opening and closing a liquid outlet 3 of the main unit, is fixedly provided in a shaft 6 and turnably arranged in the main unit 1. This shaft 6 is turned through a float arm 5 by lifting a float 4 due to a change of a liquid level 11, opening and closing the two or more liquid outlets 3, opened with their shape changed, by the rotary surface 8 controlling an inflow amount of fluid in accordance with lifting the liquid level 11. Thus by simplifying a device, it can be used as a large bore liquid level control valve for a city water service equipment or the like, while by the two or more fluid outlets with a different shape proportionally opened, pressure fluctuation can be decreased in a service water main pipe.

B. Prior Art Conventional valves with the same purpose include those with a closing member (14) that moves linearly, as shown in Figure 5, and those that open and close diaphragm valves by operating a pilot valve. Also, there were devices that used electric liquid level sensing to open and close valves using electricity. However, diaphragm valves and valves based on electrical sensing have complicated mechanisms and cannot be directly controlled by floats.

C Problems to be solved by the invention A: The conventional valve that directly controls the liquid level using a float is
As shown in the figure, since the closing member operates linearly, the effective outlet area does not change until immediately before closing, and a large amount of liquid flows.

Therefore, when closing, water hammer action occurs due to the inertia of the fluid, and the fluid pressure acting on the closing surface and the 7 o
Since the force on the liquid surface was in the opposite direction, the liquid surface wave motion caused the liquid to lose its balance and vibrate. For this reason, large-diameter valves have a problem in that their uses are limited.

Also, when the liquid level drops slightly below the closing liquid level, the
This is a disadvantage if you want to refill so that the amount of liquid increases as the liquid level gets lower. There was a problem that it was difficult to install a conduit outside the liquid outlet.

In addition, by installing a conventional valve with the top and bottom, outlet, and inlet reversed and submerged in liquid in a water tank, etc., it was possible to control the amount of liquid discharged by adjusting the liquid level. , the liquid pressure of the tank, and
If the difference in pressure on the outlet side is large and the pressure on the closing surface exceeds the buoyancy of the float, there is a problem that the closing member will not open due to the pressure.

When manufacturing a valve with a large working diameter, even if the total liquid outlet area is large, the product of the fluid volume and fluid velocity immediately before closing can be made sufficiently small, so water hammer does not occur. Also, liquid pressure and
The buoyant force of the float moves the rotating surface and the direction of the force that tries to close it is perpendicular, so it does not vibrate, and it does not become impossible to open due to a pressure difference during liquid discharge. At this time, the foot resists the force that tries to move the rotating surface because
Since it is mainly surface friction force, the lubricity of fluororesin can be used to reduce the resistance.
