Abstract
The utility model discloses a spray nozzle comprising a nozzle cover, a spray core and a nozzle holder. The nozzle cover has a trumpet-shaped spraying port at one end and a spherical mixing chamber at the other end, which are communicated with each other by a spraying hole. The mixing chamber is provided with a shoulder step on the inner wall and external threads at the end ports. The spray core is a cylindrical member with a spiral groove on the surface and a conical pressure-release hole in the middle, and is fixed on the shoulder step in a way that the height of the spray core is equal to the distance between the shoulder step and the end port of the mixing chamber and the outer diameter thereof is engaged with the inner diameter of the mixing chamber. The nozzle holder is an internally ribbed tube adapter with a step, wherein the width of the step is smaller than the wall thickness of the mixing chamber; the nozzle cover, combined with the spray core, is fixed on the step and threadedly connected with the inner thread of the nozzle holder; and an inlet water pipe is threadedly connected with the internally ribbed tube of the nozzle holder. The utility model has the advantages of simple structure, easy disassembly and cleaning, and large spraying angle; and is widely used in the fields of fire protection, environmental protection, agricultural industry and chemical industry.
Description
Technical field: the utility model relates to spraying nozzle.
Background technology: existing spraying nozzle generally all adopts integral structure, if there is impurity to block in the course of work in the shower nozzle, whole shower nozzle must be disassembled from water inlet pipe, it is effort again consuming time, its spraying nozzle core surface is the cross inclined-plane, current spray from spout after being split into water smoke through cross inclined-plane inner core bump, and fluid can not get revolving force, and the angle of its spraying is little, the scope of application is little.
Summary of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of convenient disassembly is provided, and spray angle is big, the spraying nozzle that the scope of application is wide.
Spraying nozzle of the present utility model: an end of nozzle cap is provided with horn-like spout, and the other end is provided with dome shape mixed flow chamber, and the centre is communicated with by spray orifice; Described mixed flow cavity wall is provided with the shoulder rank, port is provided with external screw thread, described spray core is that the surface is provided with helical groove, the centre is provided with the cylindrical element that the hole is pressed in the taper spray, described spray core is fixed on the described shoulder rank, it highly equals the distance of shoulder rank, mixed flow chamber to port, external diameter matches with mixed flow chamber internal diameter, described nozzle boss is the female union that is provided with step, the width of step is not less than the wall thickness in mixed flow chamber, nozzle cap is assembled together and is fixed on the step with the spray core and spins with the nozzle boss internal thread, and water inlet pipe is connected with the other end internal thread of nozzle boss.
As improvement of the present utility model, described spray core bottom has boss.Described helical groove is 3～5 and is evenly distributed.The helical groove cross section is at the bottom of the circular arc or trapezoidal.
The utility model is to achieve the above object by following technical solution: the current from water inlet pipe enter the atomizing of nozzle cap mixed flow chamber formation rotating vortex shape through spray core spray pressure hole and helical groove, spray through spout again, because rotating vortex has moment of momentum, when when spout sprays to radially diffusion, spray angle is big; When impurity blocked, the interface that is threaded of can outward winding nozzle cap and nozzle boss took out the spray core easily and cleans, and by changing the size of spraying nozzle, can change spray diameter, reaches the purpose that multipurpose is selected.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment: the utility model is further described below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1, spray core 2 in the present embodiment places on the shoulder rank 8 in nozzle cap mixed flow chamber 5, the external screw thread of port is connected with nozzle boss 3, nozzle boss 3 other ends are connected with water inlet pipe 9, the spray of spray core presses hole 4 to be arranged to taper, hole centrally aligned spout 7, the boss shape is arranged in the bottom, the helical groove 11 on spray core 2 surfaces is arranged to three and is evenly distributed, and the cross section of groove is trapezoidal, when current when water inlet pipe enters, a part presses hole 6 to enter mixed flow chamber 5 from the spray of spray core, another part enters mixed flow chamber 5 by the helical groove 11 on spray core 2 surfaces, form have moment of momentum rotary water current during from spray orifice 4 ejections to spout 7 radial diffusion, so the shower nozzle spray angle is big.When the impurity obstruction need be unpicked and washed, only need open the interface of nozzle cap 1 and nozzle boss 3, take out 2 cleanings of spray core, time saving and energy saving.
