Flow adjustable type timer

Abstract

A flow adjustable type timer is formed by connecting a mechanical timer and an electromagnetic pump in series. The flow adjustable type timer is characterized in that a roller of a triggering bump 21eof an adjusting controlling rod 21d is a magnetic rolling column body; a gear bump 21g arranged on an adjusting controlling handle of the adjusting controlling rod is a protruded body containing a cubic curve with impact resisting property; in case of adjusting flow, a potentiometer can be simply rotated, and an electromagnetic pump coil connected to a potentiometer Rw and a diode can be changed;the voltage and the current in absorbing of a soft magnetic valve element change through coils of the potentiometer and the diode, thus the flow changes, and as a result, the flow adjustable timer isformed; a valve overflowing hole in a flexible main control valve element (21) is pentagonal; a wedge filtering sheet forms a 45-degree contact angle in order to be close to Marangoni effect; a microthrough hole is drilled through laser; a fatigue-free alloy coating is plated by a vacuum coating technology; and a micro laminated composite material is manufactured by electronic printing.

Description

technical field [0001] The invention relates to a control method of water flow for environmental protection and landscaping, which is an adjustable flow timer, a high-performance anti-fouling swing sprinkler and an electromagnetic flow with a new type of energy-saving impeller suspension shaftless support for energy-saving agriculture and forestry irrigation Taking into account the water-saving method including adjustable flow drippers, 360-degree nozzles, fine-tunable thread ring size and thread pitch joints, swinging sprinklers with adjustable spraying angles, and humidity-sensing smart waterers. Background technique [0002] The desire to pursue environmental protection and landscaping is endless; there are also many patents on the control method of watering water flow, and the timing switch of garden sprinklers controlled by both sides of the long axis, such as patent US7252113B2, and Patent ZL200820120164.8 all adopts the timing switch of the garden sprinkler controlled...

Problems solved by technology

Existing products vary, and none of them are perfect; there is a certain nozzle (55ac), such as Figure 31 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ac) through the matching components and then sprayed out through the only small square hole provided on the nozzle cap as the water nozzle (55a3c). Its disadvantage is that the range of sprayed water is narrow, and it cannot have a 360-degree all-round irrigation effect.

Another nozzle (55ad) for existing products, such as Figure 32 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ad) through the matching components, and is sprayed out through the large through hole opened on the half side of the nozzle cap as the water nozzle (55a3d) , its shortcoming is that the range of sprayed water is only half, and cannot have a 360-degree all-round irrigation effect

The existing electromagnetic flowmeter is made based on Faraday's principle of electromagnetic induction. When the conductor cuts the magnetic force line in the magnetic field, an induced potential proportional to the liquid flow rate is generated, and is detected by the electrode in contact with the liquid, so that it is converted by the cable. After intelligent processing, communication and control between the flow data and the computer are realized. The existing electromagnetic flowmeter includes a measuring tube, an inlet flange, an outlet flange, electrodes, an excitation coil, a measuring tube housing, a circuit board and a display. The device, in which the measuring tube, inlet flange, outlet flange and measuring tube housing are all made of metal materials, the disadvantages of using metal materials are: the weight of the entire flowmeter is relatively large, it is inconvenient to install and maintain, and usually requires multiple people Coordinated completion affects work efficiency; and the cost of metal materials is high, making the price of the finished flowmeter more expensive; how to prevent the sprinkler from dirt is also a long-standing problem. The new fine irrigation technology requires a swinging sprinkler with an adjustable spraying angle and an adjustable flow rate. type timer
