Abstract

Constant speed adjustable dripping device, it is main to be made up of spring, bottom of bottle open bottles and three-level limit pipe, bottom of bottle open bottles are hung upside down in lower spring end, its lower end passes through flexible pipe and three-level limits pipe concatenation, third level limit bore is minimum, its outlet becomes drip, and three-level limit pipe keeps vertical attitude, liquid level line in the total low bottle of drip.Liquid level drop-out value is held equal to due to realizing that spring carries the height value of a bottle, it is constant so as to realize drop speed；Drip is adjusted in vertical direction, changes liquid level difference, is realized that drop speed is adjustable, is more up dripped speed less.

Description

Constant speed adjustable dripping device

Technical field

Constant speed adjustable dripping device, scalable liquid droping speed, range of accommodation are often to drip within 90 seconds 0.5 second often to drip, once setting Drop speed is put, drop speed is invariable, and the droplet size that the device is oozed is about 24.5mm³, the device can be used for automatic flower watering and each Plant the occasions such as dropping liquid control.

Background technology

According to investigation, existing dropper and its technology do not have constant speed function, and speed governing is also inaccurate, this be unfavorable for quantitatively, Timing pours liquid or feed flow to plant, increases the difficulty of the various dropping liquid controls in other fields, is unfavorable for economizing on liquid, apparatus of the present invention Purpose be to solve the above problems.

The content of the invention

The present invention title be:Constant speed adjustable dripping device.As shown in Figure 1, its structure includes:One-level limit pipe 1, two grades Limit pipe 2, three-level limit pipe 3.Three-level limits 3 even thickness of pipe, and interior Jing is 0.2mm, and long 1cm to 2cm, its lower end are fastened as drip 4.Respectively Within level limit pipe, Jing successives reduce, and after being sequentially connected in series and keeping vertical attitude end to end, are pressed attached by the fast adjusting slider 8 of fixable drop On montant 15, while keeping 4 height of drip less than liquid level in bottom of bottle open bottles 12.15 hypomere of montant arranges vertical drop Fast scale area 10, more down drop speed shown in scale value is bigger.

The spring 11 of 13 times suspension lightweight little spring coefficients of bracing frame, 11 lower end of spring vertically hangs the bottom of bottle of cylindricality lightweight Open bottles 12（It is projecting and vertical）, liquid can be from the bottom of bottle of opening injection bottom of bottle open bottles 12.Lightweight flexible pipe 9 is S-shaped by one-level Limit pipe 1 is connected with the bottleneck of bottom of bottle open bottles 12.In bottle is accomplished, liquid level drop-out value is just equal to spring lifting bottle height Under value boundary condition, opened according to the spring constant and its length and bottom of bottle that the computing formula of Hooke's law and volume sets spring 11 The internal diameter of mouth bottle 12, so as to keep the difference in height of liquid level and drip 4 in bottle constant, realizes the constant speed dropping liquid function of this device.

Connect liquid bucket 5 liquid is connect below liquid droping port 4.Eluate conduit 6 above eluate conduit support bar 14 in positive hook-type, The high-order mouth connection of eluate conduit 6 connects liquid bucket 5, and its low level mouth belongs to drip 7, and drip 7 grows drop, is various to need confession of such as watering flowers Liquid, 6 internal diameter of eluate conduit are 1.5 to 5 times of three-level limit pipe 3.

The operation principle and its implementation of apparatus of the present invention be：Liquid level in bottom of bottle open bottles 12 is higher than drip 4, is existed Liquid level difference, promotes liquid to move along lightweight flexible pipe 9 and limit pipe flow at different levels, and therefore drip 4 grows drop and flow to drip 7, with bottle In bottom opening bottle 12, liquid level is constantly declining, and spring 11 bounces back and lifts bottom of bottle open bottles 12, due in advance according to Hooke's law And the computing formula setting spring constant and the internal diameter of bottom of bottle open bottles 12 of volume, in almost can accomplishing bottle completely, liquid level declines Value is just equal to bottle lifting values, so as to keep the difference in height of liquid level and drip 4 in bottle constant（This requires that 4 position of drip is constant, And liquid level does not drop to below D lines, as shown in accompanying drawing 1）, due to the difference in height it is constant, so liquid from drip 4 go out to drip speed guarantor Hold constant.

Liquid flows downward in limit pipes at different levels, and as limit bore successives at different levels reduce, liquid stream is hindered by successive increase Power, ensures that liquid stream is controllable, gradually falls into drop in drip 4.

Before liquid level in bottom of bottle open bottles 12 drops to D lines, the liquid level in the bottom of bottle open bottles 12 of this device is from base It is highly constant, by the fast adjusting slider 8 of fixable drop in B lines（As shown in accompanying drawing 1）The height of drip 4 is adjusted in following scope It is low, drop speed can be linearly adjusted, drip 4 is lower, and hydraulic pressure is bigger, and drop speed is bigger, and maximum can be often dripped by 0.5 second, per drop of liquid Product about 24.5mm³；Drip 4 is higher, as long as 4 position of drip is not higher than the liquid level line B in bottom of bottle open bottles 12, drop goes out speed and heals Little, minima is about often dripped for 90 seconds, is also 24.5mm per drop volume³。

Can adjust to slide into and drip a certain position on fast scale area 10 according to needing fixable drop fast adjusting slider 8 in use, The drop speed shown in scale can be oozed, so as to reach the purpose of accuracy controlling.
