Related to two-phase fluid nozzles.

In general, a method of receiving a fluid (water) and air (air), mixing them, and spraying a mist of the mixed two fluids from a spray nozzle is widely known.

To this end, the nozzle body is configured to allow the fluid to be finely sprayed with the air by supplying air into the nozzle body through a separate pneumatic line while fluid is supplied into the nozzle body through the fluid supply line from the outside. .

Generally, a nozzle having a thinly shaped tube attached to the end of a flow path in order to eject a fluid or air into a free space at high speed is called a nozzle, and such a nozzle generally includes a nozzle body, an orifice provided in the nozzle body, and an amount of air flowing into the nozzle body. It consists of a control valve provided to adjust, and a fluid supply pipe or fluid supply portion formed in the center of the orifice.

Here, the nozzle body has a cylindrical or polygonal shape, both sides of the nozzle body is usually provided so that the inlet and the injection port are symmetrical.

In addition, an orifice is formed in the inside of the nozzle body, and a fluid supply pipe for receiving a fluid from the outside is installed at one side of the orifice.

And, one side of the nozzle body is provided with a disk-type control valve for controlling the amount of air supplied through the inlet from the outside.

The nozzle having such a configuration is provided with a liquid (water, paint, lubricant, rust inhibitor, adhesive, coating liquid (hereinafter referred to as "fluid") supplied from the outside through the fluid supply pipe formed on one side of the nozzle body and at the same time Air is supplied to the inlet of the nozzle body through the air unit.

Next, the air supplied to the inlet of the nozzle body is mixed with the fluid supplied or flowed out of the fluid supply pipe in the process of passing through the orifice through the control valve, and the fluid mixed with the air is provided on the other side of the nozzle body. Sprayed through the injection hole, depending on the fluid to be sprayed can be a semiconductor post-process, disinfection of food, mold release material on the surface of the mold, cooling, deodorizing dust removal, coating, and the like.

It is preferable to further configure the ball tap valve 273 to enable adjustment.

This is to use the buoyancy principle to block the external fluid supply path flowing from the ball tap when the fluid stored in the fluid tank 270 is a certain height.

Accordingly, by setting the fluid height stored in the fluid tank 270 as desired by the user, it is possible to adjust the injection pressure and the like injected into the spray body 250.

That is, the user can continuously check the amount of fluid inside the fluid tank 270 to eliminate the need to maintain a certain height, and when the amount exceeds a certain amount of fluid, it blocks the fluid supply area, so that the nozzle injection amount can be easily adjusted. Will be obtained.

On the other hand, the spray body 250 and the nozzle support rod 210 is composed of engineer plastic material, or stainless steel or aluminum material, and placed inside the air cap which is an injection member that can finely injected the fluid and air flow As shown in FIG. 2, the fluid nozzle 120 includes a main body 122 and a fastening part 123 formed with a screw line to be fastened along a cylindrical screw line formed at the center of the nozzle body to extend to the main body.

Conventionally, the welding structure is mainly used for fluid supply and air supply, but in the present invention, the entire nozzle assembly 200 is connected by using a valve wire from a fluid tank 270 that is an external fluid supply source and a high pressure compressor that is an air supply source. It is possible to reduce the volume of), and in particular, in the case of using the air conditioner duct for humidifying the air conditioner, it is possible to minimize the air resistance of the duct by minimizing the installation cross-sectional area.

The process of injecting a two-phase fluid mixed with liquid and air by using the injection nozzle 200 for fluid mixing having the above configuration is as follows. The fluid nozzle and injection operation is the same as the sealed spray body mentioned in the previous embodiment, and will be described with reference to the conducting surface.

First, when a fluid to be injected is supplied through the fluid supply connection valve 262b formed at one side of the spray body 250, the fluid moves inside through a flow path formed in the spray body 250. The introduced fluid is injected forward through the fluid injection hole 133 formed at the end after passing through the fluid nozzle 120.

At the same time, when the air is supplied into the spray body 250 through the air supply connection valve 261b, the supplied air moves forward again through the air passage which is the processing cross section 124 of the fluid nozzle 120.

Next, the air moved to the front of the fluid nozzle 120 is sprayed to the front side of the air cap 130 through the air injection hole 135 formed in front of the air cap 130 to maintain the state and the air cap ( Maintaining a state that is sprayed forward through the air injection hole 135 formed in the air injection guide (131, 132) of 130.

In this state, a high-pressure air is supplied into the spray body 250 and flows into the cylinder at the same time by operating a control valve or the like not shown. As the air introduced into the cylinder is expanded, the fluid is injected forward through the open injection hole 133. At this time, as the air is being injected from the air injection hole 135, the fluid is spread in the forward direction. To be injected.

In this state, if the high pressure air is blocked by operating a control valve (not shown), the fluid supply to the spray body is stopped according to the operation of the ball tap valve, and thus the injection operation is stopped.

In this case, the fluid tank 270 maintains the height difference between the spray body 250 and a predetermined interval to adjust the amount of fluid and the fluid pressure introduced by using the difference between the sound pressure using the height and the gravity difference. It is desirable to facilitate siphon injection.

That is, the fluid flowing through the fluid supply valve 262a is caused by the air introduced at a high pressure from the air supply valve 261a to collide between the fluids due to the Venturi effect, and thus finely atomized to generate a spray of fine particles. You can do it.

Accordingly, the two-phase fluid movement can be easily interlocked by simply opening and closing the incoming air control valve. That is, as described above, the inflow of the fluid from the fluid tank 270 into the spray body 250 can be controlled by the siphon method of the ball tap valve 273 in the fluid tank 270. To maximize.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains.
