Description

[Detailed description of the invention] <Field of industrial application> The present invention relates to an automatic bubble gushing device used for inspecting gas leaks in industrial and domestic gas pipes and joints between gas pipes and gas appliances. It is something.

<Prior art> Currently, gas leakage can be tested by applying foaming liquid in a container with a brush, squirting the foaming liquid with a sprayer, or by hand by pouring water and detergent into a washbasin, stirring it around, etc. I found out how to apply it etc. However, in the case of and, the foaming was uneven, gas leak inspection was incomplete, and transportation of the foaming liquid was inconvenient. In addition, although it is convenient, it is difficult to replenish the foaming liquid, and the foam cannot be ejected when the container is turned upside down.

<Problems to be solved by the invention> This invention has developed a device that uses a unique method without using the above-mentioned inconvenient method.It is more effective than the conventional method and can automatically generate uniform and fine bubbles. To provide an automatic foam generator for gas leakage inspection, which allows bubbles to flow out no matter how the container is tilted and allows easy replenishment of foaming liquid.

<Means for Solving the Problems> The present invention is an attempt to solve the above problems, and its gist is to provide a container containing a foaming liquid in a certain amount or less, and to remove the tip from the container. A nozzle that protrudes and is installed by inserting its base into the container, and a pneumatic feed pipe that sends compressed air from a compressor outside the container into the foaming liquid, and the base inlet of the nozzle is installed on any slope of the container. is installed above the water surface of the foaming liquid, and the tip of the pneumatic feed pipe is provided with a porous body for foaming the foaming liquid and a weight for submerging in the foaming liquid. Located in an automatic bubble generator for gas leak detection.

<Example> An example of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall explanatory diagram of the present invention, and 1 is a container made of polyurethane or the like, which contains a foaming liquid 2 such as soap water in a certain amount or less. The amount of foaming liquid 2 is in a transparent container 1.
or preferably at the base 3' of the nozzle as described below.
In relation to this, it is desirable to provide a mark on the transparent container 1 or to attach a liquid level gauge separately. Reference numeral 6 designates a nozzle, which is inserted into the inside of the container 1 from the upper part 18, is stopped at a flange 4 at the border between the tip 3 of the container protruding from the container, and the base 3' inserted into the container, and is screwed with a cap ring 5. are doing. This nozzle 6 has its base 3' inlet located approximately in the center of the container 1, and can be used even if the container 1 is tilted in any direction (for example, 90 degrees in FIG. 2 or 180 degrees in FIG. 3). The inlet of the nozzle base 3' is always located above the water surface h of the foaming liquid 2, thereby preventing the foaming liquid 2 from entering from the inlet of the nozzle base 3'.
Further, the nozzle 6 is made flexible by providing a bellows 7 at the base of the tip 3 attached to the container, thereby giving directionality to the nozzle. On the other hand, 8 is a portable compressor installed outside the container 1, and the switch S
The dry battery E rotates the motor M, the eccentric cam 9 moves the shaft 10 to move the air pressure feeder 11 up and down, and the check valve 12 causes the compressed air to pass through the pneumatic feed pipe 13 and from the tip 14 of the pressure feed pipe. It is designed to be sent into the foaming liquid 2. This compressor 8 can also be attached to the container 1 with a hook or the like (not shown). A weight 15 is attached to the tip 14 of the pneumatic feed pipe 13 so that the tip 14 is always submerged in the foaming liquid 2 in the container 1.
A hydrophilic porous body 16 is provided around the foaming liquid 2, and compressed air from the compressor 8 is diffused into the foaming liquid 2 through the porous body 16 to form a large number of uniform and fine bubbles on the water surface h of the foaming liquid 2. I try to make it gush upwards.

Note that the connection between the pneumatic feed pipe 13 and the container 1 is established by submerging the pneumatic feed pipe 13 into the foaming liquid 2 from the outside of the container 1 from the nozzle tip 3 through the inside of the nozzle base 3' and from the nozzle base 3' inlet. By improving airtightness and integrating it with the nozzle 6, loss during storage or transportation can be prevented.

Reference numeral 17 in FIG. 1 is a plug into which a certain amount or less of the foaming liquid 2 is poured, but this plug 17 is not necessarily necessary. The foaming liquid 2 may be injected into the container 1 from the upper part 18 of the container 1. 19 is a handle of the container 1.

<Operation> To use the present invention having the above configuration, turn on the switch S of the compressor 8, rotate the motor M, move the eccentric cam 9 and the shaft 10 to move the air pressure feeder 11 up and down, and perform the check. A fixed amount of air is constantly pumped through the action of the valve 12, and air bubbles are diffused into the foaming liquid 2 through the porous body 16 provided at the tip 14 through the air pressure feed pipe 13, thereby creating uniform and fine air bubbles on the foaming liquid surface. form. By continuously doing this, the container 1 is filled with bubbles, and the bubbles are gushed out from the nozzle 6 through the nozzle base 3' inlet. Holding the container handle 19, tilt the container 1 appropriately and place the bubbles at the gas leak test location. Attach. If a gas leak occurs, you can confirm it by seeing large bubbles forming inside the bubble. At this time, depending on the inspection location for gas leakage, the container must be moved to the inspection location and tilted sideways or upside down, but according to the present invention, the nozzle base 3' inlet is always at the foaming liquid level h. Since it is located at the top, bubbles can always flow out, and the foaming liquid 2
There is no fear that the liquid will leak out from the nozzle 6 while remaining in liquid form. In addition, since the tip of the pneumatic feed pipe 13 is provided with a weight 15 in addition to the porous body 16, it is always present in the foaming liquid 2 even when the container 1 is tilted, and bubbles are always gushing out. I try to put it in

The length of the pneumatic pipe 13 in this invention can be freely selected, and the power source can be used even when used in hazardous locations of Class 1 and Class 2 specified in the Liquefied Petroleum Gas Safety Regulations. It is also possible to safely test for gas leaks by installing the compressor used outdoors. In this case, remote control becomes possible, especially if a three-way valve (not shown) is used in the pneumatic feed pipe.

<Effects of the invention> As described above, the invention allows the container to foam and be usable in any tilted position.

Since bubbles are mechanically generated, uniform and fine bubbles are obtained, making it easier to detect gas leaks and more reliable.

Refilling the foaming liquid is easy.

When a brush or spray is used, an appropriate amount can be used only at the inspection area without contaminating the room, such as when leftover foaming liquid falls on the floor when using a brush, or when foaming liquid adheres to walls when using a sprayer.

Work efficiency is higher than applying with a brush.

The foaming liquid will not leak out of the container even if the container is used at an angle, making it convenient to transport.

Since the weight is always in the foaming liquid and the porous body is provided, it can be used reliably until the foaming liquid runs out.

Since the foam gushing container and the power supply part can be installed separately, it can be used even in dangerous locations that are easily flammable.

Furthermore, since the pneumatic feed pipe 13 is attached through the nozzle, it has excellent airtightness and is easy to store, providing excellent effects not found in conventional products.
