Detailed Description
The embodiment is as follows:
referring to fig. 1-4, a balanced variable flow nozzle for a cross flow tower is arranged on the bottom of a water tray (not shown in the figure), and comprises a hollow circular water deflector 1, a nozzle cover 2, a hollow circular uniformly distributed water sprinkling channel 3, a shower support hanger 4, a hanger connecting rod 5, a uniformly distributed shower support 6 and a buckle 7, wherein the hollow circular water deflector 1, the nozzle cover 2, the hollow circular uniformly distributed water sprinkling channel 3 and the shower support hanger 4 are coaxially arranged from top to bottom, one end of the hanger connecting rod 5 is connected to the uniformly distributed water sprinkling channel 3, the other end of the hanger connecting rod is connected to the top of the shower support hanger 4, the bottom of the buckle 7 is provided with a step part 14, the top of the buckle is inserted into the bottom of the shower support hanger 4 and is fixedly connected with the shower support hanger, the uniformly distributed shower support 6 is rotatably sleeved outside the shower support hanger 4, the bottom of the uniformly distributed shower support is supported by the step part of the buckle 7, and V-shaped water inlets 8 are symmetrically arranged on the opposite side walls of the water deflector 1.
The upper surface of the uniformly distributed shower head support 6 is provided with a plurality of guide walls 9 extending radially. The horizontal projection of the flow guide wall 9 is an arc extending counterclockwise outwards along the axis. The water conservancy diversion wall 9 can guide the circulating water that falls into 6 upper surfaces of equipartition gondola water faucet support and fall down from the edge, also can push the equipartition gondola water faucet support 6 to rotate under the hydraulic action simultaneously, and the arc structure can reduce the water resistance. The flow guide walls 9 extending anticlockwise can form gradually enlarged flow channels from the axial center to the outside on the surfaces of the uniformly distributed shower supports 6, so that the falling water flow can be dispersed more favorably, and the falling water flow can be more uniformly scattered.
And a plurality of penetrating inner ring drain holes 10 and outer ring drain holes 11 are arranged on the uniformly distributed shower head support 6 along the direction of the flow guide wall 9. The water flow falling into the upper surface of the uniformly distributed shower holder 6 can directly fall through the inner ring water drainage holes 10 and the outer ring water drainage holes 11 in sequence, so that the uniform distribution of the water flow below the shower nozzle is ensured, when the water flow is small, the water can be distributed downwards mainly through the inner ring water drainage holes 10, and when the water flow is enlarged, the water can be distributed in a mode of gradually spreading through the inner ring water drainage holes 10 and the outer ring water drainage holes 11 and from the edge, so that the uniform water distribution effect under various water quantities is realized.
And a plurality of reinforcing ribs 12 extending axially are symmetrically arranged on the outer wall of the uniformly distributed water sprinkling channels 3. And a groove 13 for accommodating the bottom wall of the water sowing plate is arranged on the reinforcing rib 12 close to one side of the sprayer cover 2. The strengthening rib 12 that the symmetry set up can make the equipartition spill 3 installation back remain stable, avoids rivers to wash off balance down, influences the spraying of equipartition gondola water faucet and falls into water. The groove 13 can block the bottom wall of the water sowing plate, and the spray head is integrally and stably arranged on the water sowing plate under the fixation of the spray head cover 2.
During the shower nozzle installation of this embodiment, insert the top of buckle 7 earlier in the equipartition gondola water faucet holds in the palm 6, insert in the bottom of gondola water faucet support gallows 4 again, accomplish fixedly, then hold in the palm 6 one side with the equipartition gondola water faucet that installs and pass the mounting hole of broadcasting the water tray bottom, then rotate the shower nozzle, make the recess 13 at strengthening rib 12 top block and broadcast the water tray diapire, realize fixing on broadcasting the water tray.
This embodiment in use, when the inflow is 30% of standard design, water level height just can spray water from the shower nozzle after rising to the height of V-arrangement water inlet 8 in the water tray, because there is a take the altitude bottom of V-arrangement water inlet 8 apart from the bottom of water tray, just so can stop because the water level crosses the vortex that leads to producing when intaking excessively, the inhomogeneous phenomenon of broadcast water that arouses, after rivers fall to equipartition gondola water faucet support 6 through equipartition gondola water faucet 3 on, broadcast through inner ring outlet 10 and outer ring outlet 11 and guiding wall 9 and fall, because rivers are less, the spray area is limited, but because equipartition gondola water faucet support 6 can rotate the watering, it is comparatively even to spray relatively, the water range of spraying can not overlap between two adjacent shower nozzles, every shower nozzle all can evenly spray in the design range. When the water inflow reaches 50% of the standard design, the water level of the water sowing disc can rise to the top of the water pouring guide 1, so that the water inflow area is the sum of the two V-shaped water inlets 8, the water inflow is correspondingly increased, the spraying ranges between the two spray heads can be overlapped, and the effect of uniform spraying can be achieved. When the water yield reaches 100% of standard design, the water level surpasses the top of water deflector 1 in the water tray, and the water yield of spraying this moment is bigger, because 6 rotatory watering of equipartition gondola water faucet support itself, the scope of spraying of every shower nozzle all reaches the designing requirement, and two adjacent shower nozzles spray the scope and overlap and stagger, still can ensure the homogeneity that sprays. The utility model discloses a shower nozzle structure can ensure all can realize the balanced effect that sprays under the minimum water yield to heat exchange efficiency has been guaranteed.
The above detailed description is specific to one possible embodiment of the present invention, and the embodiment is not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the scope of the present invention should be included within the scope of the present invention.
