Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for quantifying the amount of dripping from a water passage 16 formed in the bottom of a regulating tank 1 by keeping the water level constant. About. [0002] In order to maintain the water level, a method of using a float valve of a commercially available toilet bowl washing tank can be considered. This type of float valve is provided at the end of a water supply pipe extending into a water storage tank. By connecting a valve and connecting a valve element in this valve and a float floating in the water storage tank by an interlocking mechanism, a method is adopted in which the up-and-down movement of the float is transmitted to the valve element to control the inflow amount. [0003] Under atmospheric pressure,
As long as the water level in the tank does not fluctuate, the communication
Outflow from the mouth is constant. This is due to fluctuations in the water level.
Realized by adjusting the inflow from outside
From it, the present invention is water passing port based on the principle
Need to keep the outflow volume of the water in a fixed amount
For example, make sure that the dripping amount can be changed every season.
Target. [0004] Designed for toilet wash tanks, etc.
Attach the existing float valve to a small water supply and
Or watering a small vegetable garden,
Recruitment is difficult because of the scale. [0005] One of the obstacles in the distribution process of a small amount of fluid
Clogging of the water inlet due to dust or scale.
You. For example, if the minimum set flow rate of the constant flow element is 0.2
The limit of 5 l is that it is difficult to prevent this clogging.
It is presumed to be due to the nature of the
This is also a major problem in the field. In watering plants, at least every season
Although it is necessary to change the discharge cycle from the water supply,
The conventional float valve has a floating position
The water level is fixed so that the water level can be changed easily whenever necessary.
It is difficult to change. When the drop type float valve is constructed as shown in FIG. 1, in the control tank 13, the inner ring 8 is connected to the outer ring 7 by adjusting the pressing screw 5 and the traction screw 6. Since the tip is loosely inserted into the through hole 10 penetrated through the water amount control rod 3 because it is strongly pressed, the inflow port 2 is in the floating state.
Inflow from has stopped. As a result, when the water level in the regulating tank 1 drops,
Since the fishing tackle 9 also sinks with the float 14 and hangs on the through hole 10, the flexible water amount control rod 3 is deformed in a bow shape by the load of the loading weight 18 suspended on the float 14. I do. As a result, the tight connection between the inner ring 8 and the outer ring 7 is broken, and water from the water source is discharged into the control tank 13 via the inflow port 2. When the float 14 begins to float as the water level in the adjusting tank 1 rises, the water control rod 3 and the float 14 separate, and the connection between the outer ring 7 and the inner ring 8 is restored to the crimped state. Therefore, the amount of inflow from the inlet 2 stops. That is, when the water level of the adjustment tank 1 fluctuates, the adjustment tank 1
The float 14 floating therein repeatedly moves up and down. The present invention
Utilizing the vertical movement of the float 14 due to the fluctuation of the water level, when the water level decreases, the water injection function of the water volume control rod 3 is activated to measure the increase of the inflow, and when the water level is restored, the water flow control rod 3 is increased.
Stop the water injection function. By repeating this, the water level in the adjustment tank 1 is maintained at a constant level. As described above, in the conventional float valve,
In comparison, the structure is small and concise because of the amount of dripping,
Is also simple. The suspension wire 15 extends to a water storage tank 17 via a water passage 16, and a loading weight 18 for applying a load to the float 14 is supported by the tip thereof. That is, each time the water level increases or decreases, the suspension wire 15 is
The vertical movement while wiping the flow path prevents dust and other clogging. In this case, assuming that the radius of the water passage 16 is d1 and the radius of the suspension wire 15 is d2, the cross-sectional area applied to the water passage is π (d1 ×
d1) −π (d2 × d2). Further, in the case where the suspension wire 15 is provided with a dust removing function such as raising, it is necessary to consider the influence on the flow rate in the design stage of the outflow calculation. Further, the mounting position of the fishing tackle 9 above the float 14 determines the water level of the adjusting tank 1. The water level causes the amount of dripping from the water inlet 16 to increase or decrease. From the relation, the time interval of the start of discharge from the water storage tank can be determined also by adjusting the position of the fishing tackle 9. Therefore, it is possible to set a fairly appropriate discharge cycle even if the position of the fishing tackle 9 changes, without necessarily being concerned with the increase or decrease in the diameter of the water inlet 16 depending on the season. DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described with reference to FIGS. 2 and 3 based on an example of application of a dripping type float valve defined in claim 1 to a non-power-supply type intermittent automatic water supply device (Japanese Patent No. 2521635). This will be described with reference to FIG. The non-powered intermittent type automatic water supply device has a mechanism of discharging water when a certain amount of water is stored, and thus can be said to be an automatic water supply device having measurement and timekeeping properties. That is, as shown in FIG.
When 7 is filled, the on / off valve 20 is pulled up by the gravity of the water overflowing from the overflow port 19, and the water gate 21 is opened. If the inflow is constant, regular automatic water supply becomes possible, and it can be used as an automatic watering device for plants and the like. [00014] However, watering plants such as plants is a long time.
Requires a long and very regular discharge cycle
Is done. Therefore, the amount of dripping is very small and quantitativeness is required.
However, the function of the present invention allows the
Discharge requirements can be achieved. Also, every season
It is necessary to set an appropriate discharge cycle. In this case,
In addition to the method of changing the diameter of the water inlet 16, fishing
Several types of floats 14 having different mounting positions for the anchors 9 are prepared,
Each time, by taking measures to replace the float,
It is possible to select an appropriate discharge cycle. If dust is not sufficiently removed even when the suspension wire 15 is moved up and down due to fluctuations in the water level, the leading end of the conductive wire 12 is mounted on the top of the control tank 13 as shown in FIG. Is connected to the suspension point 24 of the weight of the balance 23 via the fulcrum 25, the vertical movement of the suspension wire 15 caused by the operation of the balance 23 every time the water is discharged, the water outlet 1
6 is periodically wiped, so that the obstacle due to clogging can be considerably prevented. Since the present invention is configured as described above, the following effects can be obtained. Compared to the existing float bubble, the structure
Small and simple, therefore the production cost is low, volume
Small and easy to use. An energy-saving automatic water supply device that does not require electricity is inexpensive.
Price and miniaturized drop type float valve
Function, and as a result,
If the spread is promoted, a big improvement in energy saving will be achieved.
Fruit can be expected. The present invention has a small size and is highly responsive such that the set water level can be easily changed, and can prevent the passage of water from being blocked by dust or water scale. It can be applied to departments that do not need it.
