Background technique
Trickle irrigation is a kind of advanced water-saving irrigation technique, has water-saving, saves fertilizer, increase production, increase income, saving of labor, saving ground, to landform
It is strong with soil suitability, and can be in conjunction with fertilising, it is easy to accomplish various advantages such as automatic control.Developing drip irrigation technique not only has
Conducive to water-saving, to improving the ecological environment and promote agricultural production modernization all significant.Therefore a kind of steady flow result is studied
Drip emitter good, that manufacturing cost is low, long service life, anti-clogging are good is very necessary.
Most widely used at present is labyrinth type drip emitter, and pressure regulation energy dissipating principle is by increasing water flow in labyrinth
Frictional head loss and local head loss in formula runner achieve the purpose that the excess energy for eliminating water flow, enable water yield
Stablize within a certain range.
But its accuracy of manufacture is not easy to control, and labyrinth path is elongated, is easy blocking.
Summary of the invention
The technical issues of present invention devises a kind of pressure-adjusting type elasticity douche, solves is that existing labyrinth type trickle irrigation is poured water
The accuracy of manufacture of device is not easy to control, and labyrinth path is elongated, is easy blocking.
In order to solve above-mentioned technical problem, present invention employs following scheme:
A kind of pressure-adjusting type elasticity douche, including cylindrical shell (2), cylindrical shell (2) are equipped with water inlet (1) and water outlet
(8), it is divided into upper plenum (3) and lower cavity by the way that disk-shaped fixed water blocking member (9) is arranged in cylindrical shell (2), intake

The area in aperture (7) and it is located above circular orifice (7), disk-shaped activity water blocking member (4) made by apparatus for adjusting position
Spacing becomes with the variation of the hydraulic pressure of water inlet (1) between disk-shaped activity water blocking member (4) and disk-shaped fixed water blocking member (9)
Change；When the hydraulic pressure is bigger, the spacing is smaller.
Further, the apparatus for adjusting position includes connecting rod (5) and spring (6), connecting rod (5) one end and disk-shaped work
Dynamic water blocking member (4) are fixedly connected, and connecting rod (5) other end is fixedly connected with one end of spring (6), and the other end of spring (6) is solid
It is scheduled on lower cavity bottom.
Further, water inlet (1) is located at upper plenum (3) bottom, and water outlet (8) is located in lower cavity sidewalls.
Further, water inlet (1), disk-shaped activity water blocking member (4), circular orifice (7), connecting rod (5) and spring (6) axis
To line of symmetry be same straight line.
Further, the water inlet (1), circular orifice (7) are identical with the diameter of water outlet (8), are 0.5~1.5mm.
Further, cylindrical shell (2) axial length is 25mm, and diameter 12mm, disk-shaped activity water blocking member (4) is directly
Diameter is 9mm, and vertical range of the circular orifice (7) apart from water inlet (1) is 10mm；The connecting rod (5) long 10mm, it is described
The center of circle of water outlet (8) is located at away from upper plenum (3) bottom 13mm.
Further, the spring (6) long 9mm under the conditions of not by external force, in the spring (6) not by external force
When, the vertical range between disk-shaped activity water blocking member (4) and circular orifice (7) is 4mm.
A kind of pressure-adjusting type elasticity douche is for agricultural or forestry trickle irrigation.
The pressure-adjusting type elasticity douche has the advantages that
(1) pressure-adjusting type elasticity douche of the present invention is when the water flow pressure of inflow is bigger, so that disk-shaped activity water blocking member
Vertical range between circular orifice is shorter, and the cross-section of river is smaller, and outflow will not increase because hydraulic pressure increases.
(2) pressure-adjusting type elasticity douche of the present invention is got over hour in the water flow pressure of inflow, disk-shaped activity water blocking member and circle
Vertical range and the cross-section of river between shape aperture is bigger, and is not more than 4mm always, and outflow will not subtract because hydraulic pressure reduces
It is small, keep outflow relatively stable always.
(3) present invention adjusts disk-shaped activity water blocking member and disk-shaped fixed water blocking member using hydraulic pressure, connecting rod and spring
Between spacing, structure is simple, and manufacture deviation is small, is not easy to plug, easy to use.

Specific embodiment
Below with reference to Fig. 1 and Fig. 2, the present invention will be further described:
A kind of pressure-adjusting type elasticity douche, including cylindrical shell 2, cylindrical shell 2 are equipped with water inlet 1 and water outlet 8, cylinder
It is divided into upper plenum 3 and lower cavity by the way that disk-shaped fixed water blocking member 9 is arranged in shell 2, water inlet 1 is located at upper plenum 3
Bottom, in the lower cavity sidewalls that water outlet 8 is located at.It is provided with circular orifice 7 in disk-shaped fixed water blocking member 9, is equipped in upper plenum 3
Disk-shaped activity water blocking member 4, the area of disk-shaped activity water blocking member 4 are greater than the area of circular orifice 7 and are located at circular orifice 7
Top, disk-shaped activity water blocking member 4 make disk-shaped activity water blocking member 4 and disk-shaped fixed water blocking member by apparatus for adjusting position
Spacing changes with the variation of the hydraulic pressure of water inlet 1 between 9；When the hydraulic pressure is bigger, the spacing is smaller.
Apparatus for adjusting position includes connecting rod 5 and spring 6, and 5 one end of connecting rod and disk-shaped activity water blocking member 4, which are fixed, to be connected
It connects, 5 other end of connecting rod is fixedly connected with one end of spring 6, and the other end of spring 6 is fixed on lower cavity bottom.
The axial line of symmetry of water inlet 1, disk-shaped activity water blocking member 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 water outlet 8, are 0.5~1.5mm.2 axial length of cylindrical shell
For 25mm, diameter 12mm, disk-shaped 4 diameter of activity water blocking member is 9mm, the circular orifice 7 apart from water inlet 1 it is vertical away from
From for 10mm；Connecting rod 5 is 10mm long, and the center of circle of water outlet 8 is located at away from 3 bottom 13mm of upper plenum.Spring 6 is not by outer masterpiece
The long 9mm under the conditions of, when the spring 6 is not by external force, hanging down between disk-shaped activity water blocking member 4 and circular orifice 7
Straight distance is 4mm.
The pressure regulation energy dissipating principle of pressure-adjusting type elasticity douche of the present invention is:
When pressure water stream is by water inlet 1, flow into upper plenum 3, disk-shaped activity water blocking member 4 is under pressure immediately, pressure
Power passes to spring 6 by connecting rod 5, and 6 compressive deformation of spring is shunk, and pulls connecting rod 6 and disk-shaped water blocking member 4 to its
It is mobile, and finally make the vertical range between the circular orifice 7 in disk-shaped activity water blocking member 4 and disk-shaped fixed water blocking member 9
Shorten, the cross-section of river reduces.Hydraulic pressure is bigger, and 6 compressive deformation of spring is bigger, make disk-shaped activity water blocking member 4 and circular orifice 7 it
Between vertical range it is shorter, the cross-section of river is smaller, so outflow will not because hydraulic pressure increase due to increase, play pressure regulation energy dissipating make
With.
Pressure-adjusting type elasticity douche of the present invention for agricultural and forestry trickle irrigation, working pressure range 0.05-0.20MPa,
Flow is 2-5L/h.
Above in conjunction with attached drawing, an exemplary description of the invention, it is clear that realization of the invention is not by aforesaid way
Limitation, as long as use the inventive concept and technical scheme of the present invention carry out various improvement, or it is not improved will be of the invention
Conception and technical scheme directly apply to other occasions, be within the scope of the invention.
