Detailed description of the invention
Nozzle is because its high functional safety and high automatically cleaning degree are suitable for spraying the process water of equal in quality and the process water of different quality especially, especially in the share of fibrous material, for example, for manufacturing the required situation of web of fiber.
As from accompanying drawing, nozzle is formed by nozzle body 1 substantially, and described nozzle body 1 holds two-piece type nozzle head.
Nozzle head self has formed and has transported fluid into until the flow channel 4 at ejiction opening 5 places.At this, flow channel 4 has circular cross section, and described cross section dwindles to ejiction opening 5 in a part.This conical contraction of flow channel 4 has been improved the pressure of fluid in the time leaving ejiction opening 5.
Two parts of nozzle head are formed by the element 2 supporting regularly and the element 3 that the flow direction 6 that is parallel to fluid supports in a movable manner.At this, the division surface 11 between two head element 2,3 is arranged essentially parallel to the center of flow direction 6 through flow channel 4.Therefore, two head element 2,3 have formed the big or small identical part haply of ejiction opening 5.
For simplified construction, fixing an element 2 and nozzle body 1 are configured to a body component.
Normally in service according to Fig. 1 and Fig. 2, the fluid pressure acting on an element 3 movably causes this element 3 overcome the power of spring 8 and be pressed against on the retainer of arranging along flow direction 67 of nozzle body 1.For producing enough large throw-on pressure, being designed and sized to that movably the head-on acting surface that point in flow direction 6, that be subject to fluid pressure of an element 3 is answered is enough large.In addition, movably an element 3 seals with respect to nozzle body 1, makes fluid can produce corresponding power.For this reason, movably an element 3 with the opposed end of ejiction opening 5 on have circular perpendicular to flow direction 6 orientations and be parallel to flow direction 6 stabilizing ring 16 of supporting in a movable manner in nozzle body 1.This stabilizing ring 16 has formed the start portion of flow channel 4 and has had the sealing protuberance 14 for sealing with respect to nozzle body 1, and described sealing protuberance 14 extend in the recess 15 of nozzle body 1.At this, recess 15 allows the slip of sealing protuberance 14 between normal operation and automatically cleaning, and has formed during automatically cleaning for the retainer of arranging against flow direction 69 of an element 3 movably simultaneously.
