Definitions

  • the invention relates to a cooling tower water distribution according to the features of the preamble of patent claim 1.
  • spray nozzles are in the water distribution pipes, which are arranged above attachments, used at equidistant intervals to evenly arranged with the finely divided water droplets below the distribution pipes spray.
  • sprayer adapter is installed between the spray nozzles and the water distribution pipe to establish the connection between the distributor pipe and the spray nozzle.
  • the most common applications are downwardly sprayed spray nozzles, which are screwed into the downwardly facing sprayer adapter. In the case of upward-spraying arrangements, the procedure described is analogous.
  • an outflow opening is introduced.
  • Two holes are placed at the side of the discharge opening, through which two screws are led outwards from the inside.
  • a washer must be placed between the screw head and the inner wall of the distribution tube.
  • the screw is fixed with the inclusion of a washer by means of a nut.
  • the thus fixed screw is used to attach the sprayer adapter.
  • the spray adapter is pressed against the distributor tube by means of two nuts which are screwed onto the screws with the inclusion of washers.
  • the present invention seeks to further develop a cooling tower water distribution to the effect that the installation times can be significantly reduced in the Sprayeradapterbefest Trent and also mounting material can be saved.
  • the cooling tower water distribution according to the invention has, on the one hand, distribution pipes for distributing cooling water and, on the other hand, spray nozzles to be fixed thereto, which are to be arranged on the distribution pipe.
  • the distribution pipe can be a hollow profile closed on the circumference, or it can also be an upwardly open profile cross-section, as in the case of a channel or trough.
  • the term distribution pipe is representative of all water-bearing cable cross-sections.
  • the advantages according to the invention are particularly noticeable in the case of closed profile cross-sections, in which the sprayer adapters can be inserted into the openings only from below, ie from outside to inside.
  • the spray nozzles are connected to the distribution tube via the spray adapter described above.
  • the special feature is that the sprayer adapter has clamping tongues which engage in the distribution pipe and via which the sprayer adapter is clamped to the distribution pipe.
  • the clamping tongues are configured so that they spring back when inserted into the outflow opening and snap automatically when reaching the mounting position behind the edge and thus are already securely held on the distribution pipe.
  • corresponding hooks are arranged at the ends of the clamping tongues.
  • a plurality of clamping tongues are arranged distributed over the circumference of the outflow opening.
  • the clamping tongues are preferably of different lengths. This is due to the fact that the clamping tongues are attached to a flat, preferably annular base body, wherein the base body is arranged in the installed position, so to speak tangentially to the distribution pipe. The different distances to the outflow opening of the distribution pipe are compensated by the different length clamping tongues.
  • the clamping tongues can spring, there is a slot between adjacent clamping tongues.
  • the clamping tongues are surrounded by a gasket resting against the distribution pipe.
  • the contour of the seal is adapted on the one hand to the outer contour of the distribution pipe and flat on its opposite side. All clamping tongues are located inside the annular seal.
  • the seal can also hold between the terminal tongues, ie seal directly in the slots.
  • the seals can also serve as a guide for the sprayer adapter during assembly by means of the projections engaging in the slots.
  • the seal is applied to the generally cylindrical outer contour of the manifold. As a result, it can not be rotated about its longitudinal axis.
  • the seal itself can be pressed against the outer contour of the distribution pipe by a support body arranged on the base body.
  • the support body may be a one-piece component of the base body.
  • the seal it is also possible for the seal to be pressed against the outside of the distribution pipe by a support body detachably coupleable to the base body.
  • This support body may for example be a ring which is screwed onto the sprayer adapter in a manner similar to a union nut in order to press the seal against the outside of the distribution pipe.
  • the sprayer adapter is thereby preloaded. That is, the clamping tongues are pressed more against the inside of the distribution pipe. As a result, the sprayer adapter is securely fixed in position.
  • the support body may be part of a spray nozzle which can be coupled to the base body.
  • Such spray nozzles are preferably screwed into an internal thread of the base body of the sprayer adapter. It is conceivable to form on the spray nozzle an outer peripheral support collar, which forms the support body to press the seal against the distribution pipe. In this way, a separate external thread for a union nut omitted.
  • the sprayer adapter thus requires only a single thread, namely an internal thread or an external thread, in order to fix the spray nozzle to the sprayer adapter.
  • the sprayer adapter can also be coupled with a lock which prevents springing back of the clamping tongues.
  • the lock is part of the spray nozzle, which projects a small piece or even completely in the region of the clamping tongues, so that they can not spring back automatically, but can only spring back when the spray nozzle has been unscrewed again.
  • the clamping tongues have at their free ends hooks, which are preferably adapted in their course to the inner contour of the distribution pipe.
  • a certain sprayer adapter fits only to a specific pipe diameter and also to a specific wall thickness of the distribution pipe.
  • Usual pipe diameters are in a range of 140 to 280 mm. Different wall thicknesses of the distribution pipes can be compensated by the fact that different thickness seals are used.
  • sprayer adapters with different colors are used to allow a clear assignment to a specific line cross section.
  • sprayer adapters with different colors can be moved in the spray nozzles, so that different flow cross sections can be seen on the basis of the color.
  • FIG. 1 shows a cross section through a distribution pipe of a cooling tower
  • Figure 2 is a section along the line II-II of Figure 1;
  • FIG. 3 is a section along the line III-III of Figure 2;
  • FIG. 4 shows a further embodiment of a sprayer adapter which is fastened to a distribution pipe of a cooling tower water distribution shown in cross-section;
  • Figure 5 is a section along the line V-V of Figure 4.
  • FIG. 8 shows an exploded view of the spray nozzle with the sprayer adapter according to FIGS. 1 to 3 and FIG
  • Figure 9 is a perspective view of the seal.
  • FIG. 1 shows a cross section through a distribution pipe, which is part of a cooling tower water distribution. This cooling tower water distribution is not shown in its entirety, since it depends on the specific embodiment of the coupling of spray nozzles (sprayer) 2 with the distribution pipe 1 in the invention.
  • the distribution pipe 1 is intended to distribute cooling water to a plurality of spray nozzles 2, which are arranged at a distance from each other below the distribution pipes 1.
  • the spray nozzles 2 are attached to the distribution pipe 1 via a sprayer adapter 3.
  • the sprayer adapter 3 is best seen in Figures 2 and 3 and the exploded view of Figure 8 can be seen.
  • an outflow opening 4 is located on the distribution pipe 1 on the underside.
  • the outflow opening 4 is circular.
  • the clamping tongues 5 are evenly distributed over the circumference of the circular sprayer adapter 3. They have in adaptation to the inner contour 6 of the distribution pipe 1 different lengths.
  • the clamping tongues 5 have their free ends hooks 7, which are adapted in their inclination angle to the inner contour 6 of the adjacent outflow opening 4.
  • clamping tongues are arranged distributed over the circumference. All clamping tongues 5 have the same width. They are evenly spaced. While the free ends of the clamping tongues 5 are provided with hooks 7, the opposite, fixed ends are formed integrally with a base body 8 of the sprayer adapter 3. It is in particular a plastic injection molded part.
  • the sprayer adapter 3 is attached to the distribution pipe 1 by a linear pushing movement. About oblique surfaces on the hooks 7 of the clamping tongues 5, the clamping tongues 5 can be resiliently pushed back during insertion. The free cuts between the mutually adjacent clamping tongues 5 are chosen so wide that they do not interfere with each other when inserting. When the sprayer adapter 3 has been inserted deeply enough into the distribution pipe 1, the clamping tongues 5 again spring outward and the hooks 7 snap behind the edge 9 of the outflow opening 4.
  • the clamping tongues 5 are surrounded in their entirety on the outside by a seal 10.
  • the seal 10 bears against an outer contour 11 of the distribution pipe 1. This means that it is designed correspondingly curved.
  • the curvature opposite side of the seal 10 is designed as a flat circular ring.
  • This side of the seal 10 is supported on a support body 12, by which the seal 10 is pressed against the outside of the distribution pipe 1.
  • the support body 12 is in this embodiment part of the spray nozzle 2, which is screwed via an internal thread 13 on the base body 8 with the sprayer adapter 3. From the figure 2 it can be seen that the Support body 12 the sprayer adapter 3 at least in the height range of its base body 8 and also partially in the region of the clamping tongues 5 on the outside completely encloses. It forms a kind of bell-shaped shield.
  • a tensile force is exerted on the sprayer adapter 3, wherein the clamping tongues 5 are loaded in the axial direction of the sprayer adapter 3 and their hooks 7 are pressed firmly against the inner contour 6 of the distribution pipe 1.
  • the support against the outer contour 11 of the distribution pipe 1 takes place by incorporation of the seal 10 by means of the support body 12.
  • the sprayer adapter 3a has an outer circumferential collar in the region of its base body 14.
  • This collar serves functionally as a support body 15, which, however, is not detachably connected to the base body 14, but is integrally formed thereon. Accordingly, the support body 15 projects in the radial direction beyond the individual clamping tongues 5 radially outward.
  • the support body 15 must be at least so large that a seal 10, which in turn is to be pressed against the distribution pipe 1, is adequately supported.
  • the figures 7a) to d) can be seen again in detail, as the individual clamping tongues 5 are inclined in their course. They follow the 3-dimensionally curved course of the inner contour of the distribution pipe.
  • FIGS. 5 and 6 show that the base body 14 tapers frustoconically in the lower area on the outside and has an internal thread 13 on its inside in the tapered area, into which spray nozzles can be inserted in a known manner.
  • the internal thread 13 protrudes up to a radially inwardly projecting collar 16, which forms a fluidic bottleneck in the base body 14 and thus in the sprayer adapter 3, 3a.
  • the collar 16 serves as a stop when screwing in the spray nozzles 2.
  • a funnel-shaped widening section connects, which expands until the inner diameter in the region of the clamping tongues 5 is reached.
  • FIG. 9 shows the seal 10 in a perspective view. It can be seen that the seal 10 has on its inner circumference a plurality of parallel to the central longitudinal axis of the seal 10 extending projections 19.
  • the projections 19 are all configured identically and are at a distance from one another, which corresponds to the circumferentially measured width of the clamping tongues 5 described above. Therefore, the projections 19 engage exactly between the clamping tongues 5 and fill a gap 18 present between two adjacent clamping tongues 5. By contouring the upper side of the seal 10, this is rotationally oriented relative to the distribution pipe 1 position-oriented.
  • the projections 19 also counteract a springback of the clamping tongues 5, so that the Spayeradapter 3, 3 a is not only secured against rotation, but also securely fixed.
