Abstract
The utility model relates to an improvement to a water curtain nozzle, which is characterized in that: an axial lifting and shrinkage regulation lantern ring is arranged at the head of a nozzle with a depth more than a gap of the mouth radius of the nozzle; an active protection wing is arranged on both sides of the gap, which opening is adjustable. Thus, the water curtain can adjust the width and thickness at will according to needs, which can improve greatly the water curtain quality and save operation cost.
Description
Technical field
Utility model relates to a kind of improved drencher that can produce the water curtain fountain.
Background technology
Common drencher all is to be vertically installed with the water guide baffle plate at the shower nozzle front end, and has less than half round cut in the shower nozzle outlet.Like this when high-velocity flow by shower nozzle directive water guide baffle plate, current are ground into countless little water droplets by bump, through collision mutually, again with very high-speed from the ejection of upwards splashing of shower nozzle breach, form fan-shaped water curtain.As described in Chinese patent 96232514,97202509 is exactly this kind structure.This drencher, its main deficiency be, because gap width fixes, thereby ejection water curtain thickness and width can not regulate, and water distribution is inhomogeneous, and it is low to form the water curtain quality, influences the projected picture effect; Secondly, the common drencher gap opened degree of depth is less than or equal to shower nozzle and goes out port radius, and this shower nozzle generally can only produce fan-shaped water curtain, and can not form semicircle water curtain, also influences the water curtain effect.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of water distribution even, the drencher that water curtain thickness can be regulated.
Another purpose of utility model is to provide a kind of can produce fan-shaped drencher to semicircle water curtain.
The utility model main purpose realizes that main the improvement is to increase the adjustable collar of an axial reduction at the shower nozzle delivery port, thereby makes shower nozzle breach aperture variable, realizes the adjustable of ejection water curtain thickness and width, and water distribution is more become evenly, and it is good to form the water curtain quality.Specifically, the utility model drencher comprises the notched shower nozzle of front end, and big to vertical water guide baffle plate with the shower nozzle outlet, it is characterized in that said shower nozzle front end has axial reduction adjustment collar.The said axial reduction adjustment collar of utility model can be in the shower nozzle outside, also can be at the shower nozzle internal orifice, makes and regulates for convenient, connects to excellent with outside thread bush especially.
But utility model strengthens shower nozzle front end notch depth for making radially maximum semicircular in shape of ejection water curtain, makes notch depth greater than pore radius in the shower nozzle outlet, sprays water curtain like this and can reach semicircle.The described notch depth of utility model is especially being excellent greater than radius 2-20mm.Utility model for a change sprays the fan-shaped subtended angle of water curtain, realizes that fan-shaped subtended angle is adjustable, also can be in shower nozzle breach both sides radially, and setting can be regulated the movable flap of aperture, by changing the flap subtended angle, realizes that the water curtain subtended angle is adjustable.
Utility model is owing to increase by the one scalable collar outside drencher front end delivery port, thereby it is adjustable to pass through drencher breach aperture, reaches ejection water curtain thickness and width-adjustable; By deepening notch depth, make it to go out port radius, thereby make ejection water curtain maximum can reach semicircle greater than shower nozzle; Aperture adjustable movable flap in breach both sides can make water curtain by fan-shaped adjustable to semicircle.Above-mentioned these have not only significantly increased the adjustable of generation water curtain, can significantly improve the quality that forms water curtain, improve projection projection source image effect, make map clear true to nature, and bright thorough bright, dynamic effect is good; And,, change flow by regulating breach aperture and movable flap according to spraying the water curtain needs, can also save the work water pump, thereby save running expense.
Below in conjunction with a kind of preferred implementation, specify utility model structure and operation principle, but embodiment not the qualification to the utility model concrete structure.
Accompanying drawing is a utility model example structure schematic diagram.
The specific embodiment
Referring to accompanying drawing, drencher comprises conical supercharging shower nozzle 1, fan-shaped or the semicircle water fender 5 of vertical with the shower nozzle outlet (or big) to vertical, the shower nozzle front end has the breach 4 that forms water curtain, the breach gap depth is greater than pore radius 2-20mm in the shower nozzle outlet, shower nozzle front end periphery is processed with external screw thread, is connected with the positioning and locking spiral shell nurse 2 and the reduction collar 3.There is the adjustable movable flap 6 of aperture in shower nozzle slit radially both sides.The shower nozzle rear end is connected with quickens fairing (not providing on the figure), makes the supercharging of current speedup.During work, current are sent into nozzle system through water pump, after acceleration and rectification processing, get to vertical water fender at a high speed through conical supercharging shower nozzle, bump forms a large amount of little water droplets mutually, the upwards ejection of splashing at a high speed from the breach slit forms a fan-shaped or semicircle water curtain in the space.Adjustment collar can obtain the water curtain of satisfied thickness, and the fan-shaped size of water curtain both can be adjust and reform change by thickness, can regulate by the movable flap in breach both sides again.
Utility model for convenience of description, said water guide baffle plate and water fender are synonym.
Claims (6)
1, a kind of drencher comprises the notched shower nozzle of front end, and big to vertical water guide baffle plate with the shower nozzle outlet, it is characterized in that said shower nozzle front end has axial reduction adjustment collar.
2,, it is characterized in that said shower nozzle front end notch depth is greater than pore radius in the shower nozzle outlet according to the said drencher of claim 1.
3,, it is characterized in that said shower nozzle front end notch depth is greater than pore radius 2-20mm in the outlet according to the said drencher of claim 2.
