Description

电子螺翼式智能小口径水表Electronic screw-wing intelligent small diameter water meter 技术领域Technical field

本发明属于水流量计量领域，尤其涉及一种电子螺翼式智能小口径水表。The invention belongs to the field of water flow metering, and in particular relates to an electronic screw wing type intelligent small diameter water meter.

背景技术Background technique

目前我国民用水表，大多数是采用旋翼式水表。这类水表的结构是，在水表壳体内的上部安装显示的指示机构，在其下部安装旋翼式计量机构，该计量机构包括测量腔和在该测量腔内测量水流量的翼轮。其工作原理是：水流从表壳进水口切向冲击叶轮使之旋转，然后通过齿轮减速机构连续记录叶轮的转数，从而记录流经水表的累积流量。这种结构的弊端是距水表进水口近的导流孔引导的水流流速快，压力大，而距离进水口远的导流孔引导的水流流速慢、压力小，而对于翼轮来说，它除受到驱动其旋转的切向力外，还受到一个迫使它偏离轴心的径向力，于是摩擦阻力增大，导致水表的灵敏度降低，对翼轮轮轴的支承还造成单边磨损，磨损后其灵敏度进一步降低，从而缩短了水表的使用寿命，造成用户使用成本的上升。At present, most of my national water meters use rotary-wing water meters. The structure of such a water meter is such that a display indicating mechanism is mounted on the upper portion of the water meter housing, and a rotary metering mechanism is installed at a lower portion thereof, the metering mechanism including a measuring chamber and a wing wheel for measuring water flow in the measuring chamber. The working principle is that the water flows from the inlet of the watch case to the impeller to rotate it, and then continuously records the number of revolutions of the impeller through the gear reduction mechanism, thereby recording the cumulative flow rate flowing through the water meter. The disadvantage of this structure is that the flow velocity guided by the diversion hole near the water inlet of the water meter is fast, the pressure is large, and the flow velocity guided by the diversion hole far from the water inlet is slow and the pressure is small, and for the wing wheel, it is In addition to being subjected to the tangential force that drives its rotation, it is also subjected to a radial force that forces it to deviate from the axis, so the frictional resistance increases, resulting in a decrease in the sensitivity of the water meter. The support of the wing wheel axle also causes unilateral wear, after wear The sensitivity is further reduced, thereby shortening the service life of the water meter and causing an increase in the user's use cost.

另一方面这些水表多数采用铜、铸铁等金属材料，容易生锈会对水质产生二次污染。如何在生产民用水表时，既要降低有色金属的资源占用并提供健康环保的水表，成为众多水表生产企业所面临的问题。On the other hand, most of these water meters use metal materials such as copper and cast iron, which are prone to rust and cause secondary pollution to water quality. How to reduce the resource occupation of non-ferrous metals and provide healthy and environmentally friendly water meters when producing civilian water meters has become a problem faced by many water meter manufacturers.

所述电子螺翼式智能小口径水表还包括止回阀1，止回阀1安装在出水口接头2末端。用于阻止水的倒流。在压力升高时，水被压缩，水表产生正转动；当压力降低时，止回阀自动关闭，水表不会产生转动。当压力再次升高时，只要压力不高过止回阀内压力，水表就不会再转；水表自转主要是水表往复多次计量才累计出很大的水量，安装止回阀可以减少水表自转的频率，也就能够很好地解决压力波动造成的水表自转问题。The electronic screw type smart small-diameter water meter further includes a check valve 1 installed at the end of the water outlet joint 2. Used to prevent backflow of water. When the pressure rises, the water is compressed and the water meter produces a positive rotation; when the pressure is lowered, the check valve automatically closes and the water meter does not rotate. When the pressure rises again, as long as the pressure is not higher than the pressure inside the check valve, the water meter will not turn again; the water meter rotation is mainly because the water meter reciprocates multiple times to accumulate a large amount of water, and the installation of the check valve can reduce the water meter rotation. The frequency can also solve the problem of water table rotation caused by pressure fluctuations.

所述电子螺翼式智能小口径水表工作过程如下：水从进水口接头12流向计量系统，带动螺翼叶轮10转动，螺翼叶轮10上的磁钢8也随之转动，产生变 化的磁场信号，信号线路板14接收磁钢8的磁场信号，并将变化的磁场信号转换成脉冲信号，传输给线路板21。线路板21接受脉冲信号，并将此脉冲信号进行数字处理，转换成流量值在液晶显示器显示；水经过计量系统后从出水口接头流出。当该水表包含通断控制系统时，线路板21接受外界信号，控制通断控制系统的通断。水经过计量系统后流向通断控制系统，最后从出水口接头流出。The working process of the electronic screw-type intelligent small-caliber water meter is as follows: water flows from the water inlet joint 12 to the metering system, and the screw wing impeller 10 is rotated, and the magnetic steel 8 on the screw impeller 10 also rotates to change. The signal circuit board 14 receives the magnetic field signal of the magnetic steel 8 and converts the changed magnetic field signal into a pulse signal for transmission to the circuit board 21. The circuit board 21 receives the pulse signal and digitally processes the pulse signal to convert it into a flow value for display on the liquid crystal display; the water flows out of the water outlet connector after passing through the metering system. When the water meter includes the on/off control system, the circuit board 21 receives an external signal to control the on/off of the on/off control system. After passing through the metering system, the water flows to the on/off control system and finally flows out of the outlet joint.

所述外界信号包括预付费卡、有线远程、无线远程等方式控制信号。 The external signal includes a prepaid card, a wired remote, a wireless remote, and the like.
