Abstract
The utility model relates to a steam mechanical atomization oil gun head. The inner cavity of a spray nozzle 2 is provided with a smooth curved surface flow channel C, and a vortex disc 3 and oil separating ring 4 form interstice fit. the A end surface of the oil separating ring 4 is a sphere, and the B end surface of a joint 7 is in an internal taper surface. A vortex ring 1 is in a double trumpet port shape, an air inlet end E is in a gradually reducing shape, and an air out end d is in a gradually increasing shape. The spray nozzle 2 is provided with a smooth curved surface flow channel C, when liquid flow passes the place, the pressure loss is small. When no steam exists or the vapor pressure is small, good atomizing property is provided. The vortex ring 1 is in a double trumpet port shape, the steam flow rate with definite pressure speeds up, and ultra-high-speed airflow is formed. The oil film is acutely flushed and broken, and good atomizing effect can be obtained.
Description
The utility model relates to a kind of steam machinery atomized oil gun head, is used for stokehold, thermal power plant oil system oil combustion device.
Now, at the oil gun that each stokehold, thermal power plant oil system is used, the nozzle flow channel of its Oil gun head is a broken line, oil stream is when flowing through this place, and the fluid head local losses is big, and docks with the plane for the plane between oil distributing ring and the joint, sealing effectiveness is poor, two interplanar shimmings, and pad is fragile.
It is little that the purpose of this utility model provides a kind of fluid head loss, the Oil gun head of good sealing effect.
The purpose of this utility model is achieved in that the nozzle chamber that makes oil gun has smooth curved surface runner; It between eddy flow tray and oil distributing ring matched in clearance; The A end face of oil distributing ring is a sphere, and the B end face of joint is an inner conical surface; Spinning steam ring is the double horn degree of lip-rounding.
On the oil system burner of stokehold, thermal power plant, use the Oil gun head that the utility model provides, because nozzle has smooth curved surface runner, so liquid stream is when flowing through this place, and loss in head is little, even under the less situation of no steam or steam pressure, still have good atomization; Because spinning steam ring is the double horn type, is the shape of De Laval noz(zle), make steam in outlet interfacial dilation speedup with certain pressure, form supersonic airstream, make full use of the kinetic energy of supersonic airstream, more tempestuously towards broken oil film.Reach good atomizing effect.The oil pressure wide ranges that is suitable for of this Oil gun head simultaneously, from 0.6Mpa to 4.5Mpa, pressure oil can both reach good atomizing effect.
Further introduce the utility model below by accompanying drawing.
Accompanying drawing is that the utility model steam machinery atomized oil gun is thrown structural representation.
Spinning steam ring 1 is at Oil gun head foremost, and its profile is the double horn degree of lip-rounding, and promptly the section of spinning steam ring 1 is De Laval noz(zle) shape, and inlet end E is a convergent shape, and steam output end d is a gradually expanded form.Spinning steam ring 1 right side is interior nut 5, and it is containing nozzle 2 again, the runner that eddy flow tray 3, oil distributing ring 4, nozzle 2 inner chambers have a smooth surface C to form, and eddy flow tray 3 and branch oil are matched in clearance between 4 also, that is to say that eddy flow tray 3 can rotate in oil distributing ring 4.The mechanism that spinning steam ring 1, nozzle 2, eddy flow tray 3, oil distributing ring 4, interior nut 5 are formed all is installed in the inner chamber of exterior nut cap 6, be installed on the joint 7 by screw thread then, and joint 7 links to each other with the oil gun conduit.Joint 7 has individual inner conical surface B because oil distributing ring 4 has a spherical end surface A, and A, B both ends of the surface compress just and can reach good sealing effectiveness.
When the fuel oil after pressurizeing flows into the spin chamber through the tangential slot of eddy flow tray 3, pressure can be transformed into the at a high speed kinetic energy of rotation, and the fuel oil of rotation is through nozzle 2 at a high speed, when the inner chamber spray orifice that is formed by smooth surface C sprays, owing to be the inner chamber runner that curve C forms, so oil flows, and loss in head is little herein.When oil during from nozzle 2 ejection, run into the steam that flows out from the steam channel of exterior nut cap 6 inner chambers and the formation of interior nut 5 outer walls, because spinning steam ring 1 is the double horn mouth, it is the passage of De Laval noz(zle) shape, steam heightens through speed herein, reaches supersonic speed, and this vapor stream collides oil film tempestuously, just, help abundant burning the abundant refinement of oil film.End face A is a sphere, and end face B is an inner conical surface, therefore compresses the back good sealing effect, and oily stream flows through this place and can not leak.Eddy flow tray 3 is a matched in clearance with oil distributing ring 4, and pressure oil can promote eddy flow tray 3 and move to nozzle 2 directions, and it is leaned against on the nozzle 2 tightly.Form complete spin chamber's inner chamber, pressure oil rotates at a high speed at this airtight inner chamber, reaches the purpose that makes oil atomization from the spray orifice ejection then.
