Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with embodiment.
Embodiment 1
Pressure-compensating water dropper, as shown in Figures 1 to 4, including base 1, block 2, flexible sheet 3, base 1 is provided with outer spiral shell
Line 4, block 2 is provided with the internal thread 5 coordinated with external screw thread 4.Base 1 and block 2 are made using PE materials, anti-agrochemicals
The corrosion of product and fertilizer and ultraviolet, long service life.
Base 1 is provided with water inlet 6, and water inlet 6 is connected with water inlet pipe 7, and block 2 is provided with delivery port 8, and delivery port 8 connects
Connected water outlet pipe 9, is radially provided with blend stop 10 in the middle of delivery port 8, delivery port 8 is divided into two outlets by blend stop 10 so that dripped
It is evenly smooth, water spray will not be formed, and debris blocking probability can be significantly reduced.
It is provided with into water flange 11 in block 2, flexible sheet 3 is arranged on in water flange 11, in water inlet flange 11 ring is provided with
Shape fixture block 12, the end face of flexible sheet 3 is relative with annular fixture block 12, and delivery port 8 is located at the water inlet center bottom of flange 11.
Annular fixture block 12 is provided with a breach 13, and the water inlet side wall of flange 11 is provided with a groove 14, groove 14 and the phase of breach 13
It is right.When the setting of breach 13 and groove 14 can prevent intake pressure larger, flexible sheet 3 is fitted completely with annular fixture block 12 and is kept off
Firmly delivery port 8, result in blockage phenomenon.
For ease of the socket part 15 that is connected with water pipe, the diameter of socket part 15 is in pre-small post-large mushroom to the front portion of water inlet pipe 7,
Facilitate water inlet pipe 7 to be connected with water pipe, and the situation of leak can be avoided the occurrence of.
Base 1 is provided with the otic placode 16 for connecting installing pipe, and otic placode 16 is provided with screw 17, for base 1 to be fixed
In installing pipe, and base 1 adopts screw connection, base 1 to adopt with block 2 and be threadedly coupled with installing pipe, convenient for dismounting and washing water dropper,
Clogging is reduced, and is capable of achieving the convenient purpose for checking.
Current from water inlet 6 enter base 1 in, apply pressure in the plane of flexible sheet 3, flexible sheet under different pressures
3 degree of deformation is different, and so as to change cross section of fluid channel area block 2 inside, when such pressure is big, soon, cross section of fluid channel is little for flow velocity；
Pressure hour, flow velocity is slow, and cross section of fluid channel is big, the effect stable so as to reach different pressures down-off.Can be widely used for booth, temperature
