DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of inserting a bag into a pressure-resistant container, injecting a liquid into the bag, and connecting the inner wall of the pressure-resistant container to the bag using a pressure-resistant hose from a water tap. Water pressure is applied to the gap. Then, since the liquid in the bag is compressed by the water pressure of the tap water, by connecting a pressure-resistant hose equipped with a watering nozzle or the like to the ejection port, the ejection amount adjustment valve is opened and the liquid in the bag is ejected from the watering nozzle. I can do it. Further, by attaching a dilution pipe, the stock solution in the bag can be diluted and jetted. The present invention relates to a hydraulic liquid pressure jetting device using water pressure of a tap as a power source.

[0006]

Embodiments of the present invention will be described below. I. The pressure vessel (1) has a water supply valve (3), an air vent valve (6), a water drain valve (5), and further has a bag insertion port (13) and convex portions of joints (01), (02), and (03). ing. And since the pressure-resistant container (1) is made so that the internal bag (7) can be visually checked, the amount of liquid can always be confirmed. B. The bag (7) is elastic, and the bag opening (14) has a role of packing. C. The pipe section (17) is provided with a cleaning valve (4) an ejection amount adjusting valve (8) an injection valve (10) an injection port (11) a water supply port (2) an injection port (9) and a concave portion of the joint (01) (02). And fittings (04)
(05). The same packing as the packing (31) is used for the joint surfaces of the joints (04) and (05). D. Fittings (01) (02) (04) (05) and (03)
The joint recess of (06) is assembled by the following method shown in FIGS. 3, 4, and 6. Insert piping into each joint recess. Then, the claw ring (15) is screwed into the threaded portion at the tip of the pipe and fixed. E. When the liquid inside the bag (7) runs out during use, the bag (7) is pushed up by the water pressure of the tap water, and is sandwiched by the ejection amount adjusting valve (8). Therefore, as shown in FIG. 3, a bag ejection prevention wall (16) having a thin liquid ejection hole is provided on the bag (7) side of the ejection amount adjusting valve (8) in order to prevent this. The present invention has the above structure. Then, as shown in FIG. 2, the bag (7) is inserted from the bag insertion port (13) at the upper part of the pressure-resistant container (1), and the bag opening (14) is placed on the upper surface of the projection of the joint (02). Then, a packing (3
Put 1). Next, the joint (01) (0
The concave part of 2) is joined to the convex part of the joints (01) and (02) of the pressure vessel (1), and the concave parts of the joints (01) and (02) are turned and tightened, and connected and fixed to the pressure vessel (1). . After the above assembly is completed, it is used in the following procedure. Connect the tap to the water supply port (2) using a pressure-resistant hose. Air vent valve (6)
Open the injection valve (10) and open the bag (7) inside the pressure vessel (1).
The liquid is injected from the injection port (11) while observing, and an appropriate amount is stored in the bag (7), and then the injection valve (10) is closed. Next, both the faucet and the water supply valve (3) are fully opened, and water is supplied to the gap between the bag (7) and the inner wall of the pressure-resistant container (1). When all the air is pushed out from the inside of the pressure vessel (1), the air vent valve (6) is closed. Then, the inside of the pressure vessel (1)
The water pressure is the same as that in the water pipe. Then, when the ejection amount adjusting valve (8) is opened, the liquid inside the bag (7) compressed to the water pressure of the tap is pumped, and is ejected from the ejection port (9) through the piping. Therefore, when the liquid to be injected into the bag (7) is paint, a pressure-feed roller brush or a pressure-resistant hose equipped with a paint pressurized spray nozzle is connected to the ejection port (9), so that roller brush or
Can be spray painted. The following is a modification in which the jet port (9) of the present invention is removed and a dilution pipe (18) is attached thereto. As shown in FIGS. 5, 6, and 7, the joint (0
Remove the recess of 5) together with the packing. Then, the dilution pipe (18) of FIG. 5 is joined to the joint (03) of the pressure vessel (1) and the projection of the joint (05) of the pipe section (17), and a new dilution pipe (18) is formed. Turn the recesses of the joints (06) and (03) to tighten and fix. Next, the air release valve (6) and the injection valve (1
0) is opened and a stock solution for dilution is injected from the injection port (11). After storing an appropriate amount in the bag (7), the injection valve (10) is closed. Subsequently, the faucet and the water supply valve (3) are fully opened, and water is supplied to the gap between the inner wall of the pressure-resistant container (1) and the bag (7). Then, the supplied water is ejected from the diluent ejection port (19) through the air vent valve (6). The amount of water is adjusted by the air vent valve (6) so that the amount of the jetted gas becomes an appropriate amount. At this time, the ejection amount adjusting valve (8) is opened in accordance with the scale indicated by the handle of the air release valve (6), and the ejection amount is adjusted in accordance with the scale so that the desired dilution ratio is obtained. Then
The undiluted solution in the bag (7) compressed by the water pressure of the tap water is sent under pressure and spouted from the undiluted solution outlet (21) of the packing (20) with the dilution tube inside the dilution pipe (18) in FIG. . There, it mixes with the water which passed through the air vent valve (6), and becomes the target diluent, and jets out from the diluent jet (19). Further, even during use, the dilution rate can be freely changed by opening and closing the ejection amount adjusting valve (8). Therefore, all liquids can be injected into the bag (7). And, by replacing the nozzle connected to the diluting liquid ejection port (19) with a pressure-resistant hose according to the type of liquid inside the bag (7), it can be used for a plurality of applications.
Next, a cleaning method after use will be described. Open the drain valve (5) and drain the water inside the pressure vessel (1). next,
The faucet, the air vent valve (6) and the cleaning valve (4) are opened, and water is supplied into the bag (7). And after collecting the appropriate amount of water,
The cleaning valve (4) and the drain valve (5) are both closed. Next, the water supply valve (3) is opened, and water is supplied to a gap between the inner wall of the pressure-resistant container (1) and the bag (7). Then, after bleeding the air inside the pressure-resistant container (1) from the air bleed valve (6), the air bleed valve (6) is closed. Then, when the inside of the pressure vessel (1) is compressed by the water pressure of the tap water, when the ejection amount adjusting valve (8) is opened, the water mixed with the liquid inside the bag (7) flows from the ejection port (9). Since it is ejected, the inside of the bag (7), the inside of the pipe, and the ejection port (9) can be washed. Further, when the dilution pipe (18) is used, cleaning can be performed by the same method as described above.

[0008]

Since the present invention is configured as described above, it has the following effects. I. It has a very simple structure in which fittings and valves are attached to the three parts of the pressure-resistant container, bag, and piping. B. Since the power source is the water pressure of tap water, consideration is given to issues such as environmental impact and resource depletion. Further, since no sound is generated, no discomfort is given to the user or the surroundings due to noise. C. As the dilution device, the dilution ratio can be freely changed by operating the valve even during use, so that it can be adapted for each purpose. Further, the cleaning of the apparatus after use can be performed without soiling the hands. D. Since it has two functions, ie, pressurized jetting and dilution jetting, all of what can be called liquid except paint, disinfectant, and liquid fertilizer are put in the bag in the pressure-resistant container. In addition, various types of spray nozzles, spray nozzles, and the like, as well as spray coating by a paint pressurization method and coating by a pressure-feeding roller brush can be applied to the jet port, so that the spray port can be used for a wide range of applications. E. The tap water drained from the drain valve used as a power source can be reused, resulting in effective use of resources.
