Description

Multi directional injection valve < RTI ID = 0.0 >

The present invention relates to a multi-directional injection nozzle for dispersing and injecting fluid flowing in one direction in various directions, and more particularly, to a spray nozzle capable of freely adjusting an injection point and applicable to existing pipes.

In general, the injection nozzle is a device for increasing the speed and pressure of a supplied fluid and rapidly injecting the fluid. Since the injection direction is limited to only one point, there is a limit in utilization.

For example, when the injection nozzle is used for cleaning the inner wall of the drain pipe, it is necessary to spray the washing water over the entire inner wall of the drain pipe. In the conventional injection nozzle, since the direction of spraying the washing water is fixed at only one point, A plurality of injection nozzles must be installed. In order to install a plurality of spray nozzles on the pipe provided with the wash water, the pipe must be entirely modified and the spray nozzles must be coupled to each pipe in each direction. This complicates the manufacturing process and requires a lot of manufacturing time There is a problem.

Further, in order to mount a plurality of injection nozzles on one pipe, it is necessary to process the pipe, and there is a problem that the existing pipe can not be used as it is.

Hereinafter, an embodiment of a multi-directional injection nozzle according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are a perspective view and a cross-sectional view of a multi-directional injection nozzle according to the present invention.

The injection nozzle according to the present invention is an apparatus for injecting a fluid provided through a pipe 10 at a high pressure. The fluid can be injected by dividing the fluid vertically and horizontally, freely adjusting the fluid injection point, (10) can be mounted as it is, even if it is not separately processed.

That is, as shown in FIGS. 1 and 2, the injection nozzle according to the present invention includes a connection pipe 110 formed in a hollow pipe shape and having different pipes 10 at both ends in the longitudinal direction, And a plurality of spray holes 120 formed to penetrate the side wall of the body 110.

When two different pipes 10 are connected by the injection nozzle according to the present invention, when the high pressure fluid is supplied through the pipe 10 on either side, the fluid passes through the inside of the connection pipe 110 And a part thereof is discharged to the outside through the spray hole 120. At this time, the injection holes 120 are formed on the upper and lower and left and right sides of the coupling pipe 110, respectively. The fluid passing through the injection nozzle according to the present invention is divided into upper and lower and left and right directions. Therefore, when the injection nozzle according to the present invention is installed in the drain pipe and the washing water is supplied to the pipe 10 at a high pressure, the washing water injected through the injection nozzle is sprayed in the vertical and lateral directions, The effect can be obtained.

Further, since the multi-directional injection nozzle 100 according to the present invention is mounted between two pipes 10 connected in series, it is possible to freely change the injection point by appropriately selecting the length of the pipe 10 . For example, when a plurality of pipes 10 are connected in series, two adjacent pipes 10 are connected to the multi-directional injection nozzle 100 according to the present invention at a point where fluid injection is required, The user can freely select the injection point of the fluid by connecting the adjacent two pipes 10 with the ordinary coupler.

When the injection hole 120 is formed in the diameter direction of the connection pipe 110, a pressure loss is greatly generated when the fluid flowing in the pipe 10 flows into the injection hole 120, The holes 120 may be formed to pass through the sidewalls of the coupling pipe 110 in a direction intersecting the diametrical direction of the coupling pipe 110, that is, through the sidewalls of the coupling pipe 110 diagonally toward the front .

4 and 5 are a side view and a cross-sectional view of the second embodiment of the multi-directional injection nozzle 100 according to the present invention, and Fig. 6 And FIG. 7 is a longitudinal sectional view and a cross-sectional view showing the coupling structure of the first coupler 131 and the second coupler 135.

As shown in FIG. 1 and FIG. 2, the multi-directional injection nozzle 100 according to the present invention may be composed of a single coupling pipe 110 connecting two pipes 10, Or may be constructed in a structure in which they are integrally combined.

That is, the multi-directional injection nozzle 100 according to the present invention includes a first coupler 131 formed in a hollow tube shape and having one side mounted on the end of one of the pipes 10, And a second coupler 135 mounted on the other end of the pipe 10 and having the other end connected to the other end of the first coupler 131. The first coupler 131 and the second coupler 135 So that the internal fluid can be injected through the empty space of the housing.

The first coupler 131 is coupled to the second coupler 135 so that the amount of fluid injected through the first coupler 131 and the second coupler 135 can be stably maintained. A plurality of protrusions 132 protruding in the direction of increasing the inner cross-sectional area is formed on the outer peripheral surface of the end of the second coupler 135. On the outer peripheral surface of the end of the second coupler 135 which is engaged with the first coupler 131, It is preferable to form an inlet portion 136 which is inserted in the direction in which the inner cross-sectional area decreases and which is fitted to the protrusion 132 in a fitting manner. When the protrusion 132 is formed in the first coupler 131 and the inlet portion 136 is formed in the second coupler 135 as described above, the space between the protrusion 132 and the inlet portion 136 is filled with the pipe The operator can appropriately select the amount of the fluid to be injected by adjusting the size of the protrusion 132 and the inlet 136. The protrusion 132 and the inlet 136 The direction of the fluid to be injected can be adjusted appropriately.

Although the cross section of the protrusion 132 and the inserting section 136 is triangular in this embodiment, the protrusion 132 and the inserting section 136 may have a semicircular or circular arc cross section. . That is, the shape of the projecting portion 132 and the inlet portion 136 may be variously applied as long as a space through which the fluid can be injected is secured between the projecting portion 132 and the inlet portion 136. The injection pressure of the fluid discharged between the protrusion 132 and the inlet 136 is increased or decreased by the distance between the protrusion 132 and the inlet 136 so that the operator can adjust the injection pressure of the fluid The protrusion 132 and the inlet 136 may be configured to be bent by the force of the operator. For example, when the first coupler 131 and the second coupler 135 are made of a thin metal plate, the projecting portion 132 and the inlet portion 136 are also made of a thin metal plate, The fluid injection pressure may be increased by narrowing the gap between the protrusion 132 and the inlet 136 and the fluid injection pressure may be decreased by widening the gap between the protrusion 132 and the inlet 136.

The protrusion 132 is formed in the second coupler 135 so as to reduce the pressure loss of the fluid when the fluid flowing in the pipe 10 flows into the space between the protrusion 132 and the inlet 136. [ And the depth of the inlet portion 136 is gradually increased toward the first coupler 131. In this case, the height of the inlet portion 136 is gradually increased toward the first coupler 131. In other words, When the projecting portion 132 and the inlet portion 136 are inclined, the high-pressure fluid flowing in the pipe 10 flows into the inclined flow path between the projecting portion 132 and the inlet portion 136, , It is possible to more effectively prevent the pressure drop of the fluid and thus to maintain the injection pressure of the fluid at a very high level.

Since the end of the inlet 136 extends more inward than the inner surface of the second coupler 135, a certain amount of the fluid flowing through the inner space of the second coupler 135 rides on the inclined surface of the inlet 136 The advantage of being discharged to the outside naturally, that is, the amount of the fluid to be injected is kept constant.

On the other hand, if the fluid ejection direction is close to the vertical, the pressure loss of the fluid is very large, and if the fluid ejection direction is close to horizontal, the effect of dispersing the fluid is small. That is, the inclination angle of the protrusion 132 and the inclination angle of the inlet portion 136 are inclined so as to have an angle of 30 to 60 degrees with respect to the longitudinal direction of the pipe 10, respectively, so that the protrusion 132 and the inlet portion 136 is also set to be inclined so as to have an angle between 30 degrees and 60 degrees with respect to the longitudinal direction of the pipe 10. [

In addition, when the projecting portion 132 and the inlet portion 136 are simply brought into contact with each other in a laminated structure, the first coupler 131 and the second coupler 135 can independently rotate the longitudinal center axis of the unit tube with the rotation axis The outer end of the inlet 136 in the width direction is preferably tightly coupled to the inner end in the width direction of the protrusion 132 as shown in FIG. Since the first coupler 131 and the second coupler 135 can not independently rotate when the widthwise outer end of the lead portion 136 is in close contact with the widthwise inner end of the lead portion 132, Even if they are applied, they can not be separated from each other, and the integrated state can be stably maintained.

8 is a side view showing the direction of spraying the washing water in the multi-directional injection nozzle 100 according to the second embodiment of the present invention.

8, the fluid in the pipe 10 flows through the space between the projecting portion 132 and the inlet portion 136 and is inclined without a large pressure drop. As shown in FIG. 8, when the multi-directional injection nozzle 100 according to the present invention is used, As shown in FIG. The protrusions 132 are formed on the upper and lower sides and the left and right sides of the first coupler 131 so that the fluid can be evenly distributed in the vertical and lateral directions. 135, respectively.

Of course, the projecting portion 132 and the inlet portion 136 may be formed in the first coupler 131 and the second coupler 135, respectively, six or eight, respectively, so as to more evenly distribute the direction of injection of the fluid have. However, if the protrusion 132 and the inlet 136 are formed too much, the pressure of the fluid to be sprayed may be lowered. Therefore, the number of the protrusion 132 and the inlet 136 may be varied It is desirable to select them appropriately according to the conditions.

While the present invention has been described in detail with reference to the preferred embodiments thereof, the scope of the present invention is not limited to the specific embodiments but should be construed in accordance with the appended claims. Those skilled in the art will appreciate that many modifications and variations are possible without departing from the scope of the present invention.
