Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, the present invention will be further described:
A kind of pressure-adjustable type elasticity douche, including cylindrical shell 2, cylindrical shell 2 is provided with water inlet 1 and outlet 8, passes through to arrange discoideus fixing water deflector 9 and be divided into upper plenum 3 and lower cavity in cylindrical shell 2, water inlet 1 is positioned at bottom upper plenum 3, in the lower cavity sidewalls that outlet 8 is positioned at.Discoideus fixing water deflector 9 has circular orifice 7, upper plenum 3 is provided with discoideus activity water deflector 4, the area of discoideus activity water deflector 4 is more than the area of circular orifice 7 and is positioned at above circular orifice 7, and discoideus activity water deflector 4 makes spacing between discoideus activity water deflector 4 and discoideus fixing water deflector 9 change along with the change of the hydraulic pressure of water inlet 1 by apparatus for adjusting position；When described hydraulic pressure is more big, described spacing is more little.
Apparatus for adjusting position includes connecting rod 5 and spring 6, and connecting rod 5 one end is fixing with discoideus activity water deflector 4 to be connected, and connecting rod 5 other end is fixing with one end of spring 6 to be connected, and the other end of spring 6 is fixed on lower cavity bottom.
The axial line of symmetry of water inlet 1, discoideus activity water deflector 4, circular orifice 7, connecting rod 5 and spring 6 is same straight line.Water inlet 1, circular orifice 7 are identical with the diameter of outlet 8, are 0.5～1.5mm.Cylindrical shell 2 axial length is 25mm, and diameter is 12mm, and discoideus activity water deflector 4 diameter is 9mm, and described circular orifice 7 is 10mm apart from the vertical dimension of water inlet 1；The long 10mm of connecting rod 5, the center of circle of outlet 8 is positioned at from 13mm place bottom upper plenum 3.Spring 6 is long 9mm not by External Force Acting when, and when described spring 6 is not by External Force Acting, the vertical dimension between discoideus activity water deflector 4 and circular orifice 7 is 4mm.
The pressure regulation energy dissipating principle of pressure-adjustable type elasticity douche of the present invention is:
When pressure water stream is by water inlet 1, flow in upper plenum 3, discoideus activity water deflector 4 is under pressure immediately, pressure passes to spring 6 by connecting rod 5, spring 6 compressive deformation shrinks, and pull connecting rod 6 and discoideus water deflector 4 to move to it, and finally make the vertical dimension between the circular orifice 7 in discoideus activity water deflector 4 and discoideus fixing water deflector 9 shorten, the cross-section of river reduces.Hydraulic pressure is more big, and spring 6 compressive deformation is more big, makes the vertical dimension between discoideus activity water deflector 4 and circular orifice 7 more short, and the cross-section of river is more little, and then outflow will not increase because hydraulic pressure increases, and plays pressure regulation energy dissipating effect.
Pressure-adjustable type elasticity douche of the present invention is for agricultural and forestry drip irrigation, and working pressure range is 0.05-0.20MPa, and flow is 2-5L/h.
Above in conjunction with accompanying drawing, the present invention is carried out exemplary description; the realization of the obvious present invention is not subject to the restrictions described above; as long as have employed the various improvement that the design of the method for the present invention carries out with technical scheme; or the not improved design by the present invention and technical scheme directly apply to other occasion, all in protection scope of the present invention.
