Embodiment
Below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 1, a kind of high precision energy-conservation adjustable type flow cavitation result measuring apparatus disclosed in the utility model, and existing flow cavitation result measuring apparatus is similar, comprises valve body 1, solenoid valve 2, flowmeter 3; Valve body 1 two ends are connected with water inlet pipe and rising pipe respectively, valve body 1 is provided with the mounting hole installing flowmeter and solenoid valve, solenoid valve 2 and flowmeter 3 are arranged within valve body respectively, and the on off state of valve body when solenoid valve 2 controls power on/off, flowmeter 3 judges the number by discharge.Improvement of the present utility model is, flowmeter comprises flow promoter regulator 301, impeller 302, central shaft 303, magnet ring 304, Hall element 305, snap ring 306 and over cap 307; Flow promoter regulator 301 is arranged on the flowmeter inlet end of valve body 1, the top of impeller 302 arranges magnet ring 304, Hall element 305 is arranged on described magnet ring 304 upper end, central shaft 303 on valve body 1 is through impeller 302 and magnet ring 304, load the draw-in groove on 303 central shaft tops again with snap ring 306, impeller 302 and magnet ring 305 are fixed.The top of flowmeter arranges the over cap 307 of protection inner structure.
Principle of work of the present utility model is as follows: the direction of what in figure, arrow represented is current.When power of electromagnetic valve is connected, valve body is in valve opening state, and now current first enter from the water inlet of valve body, are flowed out by water outlet end.Wherein, current are first through flow promoter regulator, the size of initial-flow can be regulated according to the demand of use occasion and client, then at current through flowmeter, impeller starts along with current around central axis, impeller drives magnet ring to rotate, and rotating speed changes along with fluctuations in discharge, Hall element exports corresponding pulses signal, feeds back to controller, by the size of controller according to pulse, thus judge by discharge number.When deenergization time, closed electromagnetic valve, cut-off current.
In traditional product, flowmeter is generally adopt suspension type impeller structure, the stainless steel ball that impeller internal is inlayed, is then affiliated on center shaft, because central shaft contacts for a long time with the stainless steel ball being set in impeller internal, rotates, and then produce wearing and tearing, and the excesssive gap of central shaft and impeller, impeller middle rocking tendency of looking for a job can be caused excessive, unstable, time one is of a specified duration, and precision will reduce.In order to address this problem, the utility model adopts direct insertion flap-type blade wheel structure, and central shaft is directly through impeller and magnet ring, the draw-in groove on central shaft top is loaded again by snap ring, impeller and magnet ring are fixed, eliminates stainless steel ball, to reduce the wearing and tearing brought with contacting of central shaft; Also reduce the gap of central shaft and impeller, impeller rocking tendency is at work reduced greatly, and central shaft have employed more wear-resisting material in addition, reduces wearing and tearing, thus substantially increases precision.
Use bistable pulse coil in solenoid valve of the present utility model, compared with adopting solenoid with existing solenoid valve, bistable pulse coil is more energy-conservation, low-power consumption, long service life.Common solenoid valve is valve opening when being energized (being generally 12V), and valve is closed in power-off, so its long-time continual power supply just can work; And bistable pulse coil working voltage is generally 4 ~ 6V, only need forward to connect general about 1S, valve will be opened, and at this time, just do not need continuation to be energized, its valve of deenergization also can not be closed; Oppositely switch on power valve closing.Therefore, bistable pulse coil is more energy-conservation, low-power consumption, long service life.
This external flowmeter inlet end adds flow promoter regulator can carry out adjustment initial-flow according to environment for use situation and customer demand.Above-mentioned improvement can effectively improve Product Precision and serviceable life, and its precision can be controlled in ± 0.3% >=1ms, in ± 3%≤1ms.Higher than flow accuracy ± 10% of traditional product far away, and the flow accuracy of this series products international the highest be only ± 3%.Relative to prior art, the utility model will have good marketable value and environment protection significance.
The present embodiment object is to make professional and technical personnel in the field understand the technical solution of the utility model according to it and to be implemented; the protection domain of this patent can not be limited with it; all distortion done according to the utility model disclosure technology, all fall within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with content described in claims.
