Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 and 2, the embodiment of the utility model discloses a coal-winning machine cylinder atomizer, including high-pressure water pump, control valve, coupling, high pressure nozzle, wherein, high pressure water pump passes through high-pressure water pipe and carries the high pressure water to the control valve, and the circulation and the closing of control valve control pipeline are the coupling to the control valve other end, and high pressure nozzle is connected to the coupling, can adopt the threaded connection mode fixed between coupling and the high pressure nozzle, and finally in high pressure water entered into high pressure nozzle, the coupling can adopt general running water coupling in the current market. In this embodiment, the high pressure nozzle includes a nozzle holder 1 and a nozzle core 2, the middle of the nozzle holder 1 is hollow, the nozzle core 2 is inserted into the cavity of the nozzle holder 1 from the tail of the nozzle holder 1, the cavity of the nozzle holder 1 has a shape matched with the external structure of the nozzle core 2, one end of the nozzle core 2 is communicated with a pipe joint, the upper portion of the nozzle holder 1 is provided with a plurality of peripheral spray holes 11 arranged along the periphery, the middle of the nozzle core 2 is provided with a hollow hole, the hole is communicated with the pipe joint, the hole diameter is just matched with the inner hole diameter of the pipe joint, water in the hole comes from a high pressure water pump, the horizontal height of the water outlet hole of the nozzle core 2 is slightly lower than or flush with the horizontal height of the peripheral spray holes, the peripheral spray holes can be more than two, such as three or four, the plurality of spray holes are arranged at equal intervals, the top, wherein, nozzle core 2 is the frustum type, and the diameter on its upper portion is less than the diameter of lower part, and the frustum type contains the triplex, lower part, upper portion and connecting portion, and the lower part diameter is great, and the upper portion diameter is less than the lower part diameter, and lower part and upper portion are connected to connecting portion, and connecting portion are the slope form, and the diameter of lower part is great, and the water yield that conveniently gets into from the connector is abundant, goes to upper portion behind the connecting portion of slope form, sets up the gentle transition that the slope makes things convenient for rivers, and the upper portion diameter is less relatively, makes things convenient for. Another practicable manner regarding the nozzle core 2 is that the nozzle core 2 is provided in a shape that tapers from the bottom to the top. In addition, the diameter of the opening at the center of the top of the nozzle holder 1 is relatively small, that is, the opening is configured to be a ladder shape in the figure, which facilitates the rapid spraying of the high-pressure water mist, and the opening at the top of the nozzle holder 1 may also be configured to be a plurality of (for example, more than two), not only one central opening as illustrated in the embodiment.
In this embodiment, the diameter of the peripheral nozzle hole 11 gradually increases from the cavity of the nozzle holder 1 to the outside of the nozzle hole, and in addition, the peripheral nozzle hole 11 may be slightly inclined upward by a small angle, so that the water mist sprayed from the nozzle core 2 can be sprayed out along the peripheral nozzle hole to form a plurality of spraying directions, and since the diameter of the nozzle hole gradually increases, the sprayed water mist is a sector, the spraying area is increased, and the nozzle hole is slightly inclined upward, so that the water mist can fall down to form a parabola, and the coverage area is wider.
In this embodiment, the center lines of the central nozzle hole 12 and the peripheral nozzle holes 11 intersect at a point on the central axis of the cavity of the nozzle holder 1, so that the high-pressure water injected from the nozzle core 2 is uniformly injected toward the peripheral nozzle holes 11 and the central nozzle hole 12.
In this embodiment, the tail of the nozzle holder 1 is spherical. The round spherical surface is adopted, the contact of the cylindrical edges and corners in the past is avoided, the nozzle is more convenient to adjust in the installation process, and the accurate control of the angle can be realized.
