Description
技术领域technical field
本发明涉及建筑领域，尤其涉及一种用在不同用途的，主要是日常用的冷水或热水供水系统中的水表流量计，还涉及水表流量计的电路。所述水表流量计安装在金属表体上，其接入管道系统的通道是能防水的，通道内设置有叶轮，所述叶轮与磁性半联轴节传动连接在一起。所述半联轴节与水表流量计的配对的半联轴节有反应，所述水表流量计能算出流经水表表体通道的水的流量。The invention relates to the field of construction, in particular to a water meter flowmeter used in different purposes, mainly in daily cold water or hot water supply systems, and also relates to a circuit of the water meter flowmeter. The water meter flowmeter is installed on the metal surface body, and the channel connected to the pipeline system is waterproof, and an impeller is arranged in the channel, and the impeller is connected with the magnetic half-coupling through transmission. The half-couplings react to the mating half-couplings of the water meter flowmeter which can calculate the flow of water flowing through the channel of the water meter body.
背景技术Background technique
已知一种水表计数组件，包括表体；水表读数可视的机械数字计数装置；流量计磁性半联轴节，所述磁性半联轴节安装在表体内能转动并与配对的磁性半联轴节有磁反应，所述配对的磁性半联轴节与设置在表体通道内的叶轮传动连接在一起；传动连接流量计磁性半联轴节与机械数字计数装置的齿轮组；偏心固定在齿轮组其中一个齿轮上的永磁体；安装在表体内能与永磁体产生周期磁反应的常开簧片继电器；将两个簧片接在水表电路上的两根导线；所述两根导线连接到远程水量电子统计系统上(CN2331961Y，国际分类号G01F1/56，1999)。A known water meter counting assembly includes a meter body; a mechanical digital counting device with visible water meter readings; a magnetic half coupling of a flow meter, and the magnetic half coupling is installed in the meter body and can be rotated and connected to a paired magnetic half coupling. The shaft joint has a magnetic response, and the paired magnetic half coupling is connected with the impeller in the channel of the meter body; the transmission connects the magnetic half coupling of the flowmeter with the gear set of the mechanical digital counting device; the eccentricity is fixed on A permanent magnet on one of the gears of the gear set; a normally open reed relay installed in the meter body that can generate a periodic magnetic reaction with the permanent magnet; two wires connecting the two reeds to the water meter circuit; the two wires are connected On the remote water volume electronic statistics system (CN2331961Y, international classification number G01F1/56, 1999).
在已知的水表流量计中，通过外围的电子系统可以远程读取读数，在所述电子系统上连接有用来统计簧片继电器脉冲的水表电路导线，所述脉冲是由在齿轮组齿轮上转动的永磁体磁场的影响下簧片继电器接触点周期性地闭合产生的，这个永磁体固定在齿轮组上。In known water meter flowmeters, readings can be taken remotely by means of a peripheral electronic system to which are connected the water meter circuit wires for counting the reed relay pulses which are driven by the The contact points of the reed relay are periodically closed under the influence of the magnetic field of the permanent magnet, which is fixed on the gear set.
但是在已知的技术方案中，由于外部永磁体使簧片继电器闭塞，对水的消耗总量计算可能会有误差。固定在水表表体上的这种永磁体会使簧片继电器转变成常闭状态。However, in the known technical solution, since the external permanent magnet blocks the reed relay, there may be errors in the calculation of the total consumption of water. This permanent magnet, fixed to the body of the water meter, turns the reed relay into a normally closed state.
此外，连接到已知水表流量计的簧片继电器上的脉冲计数器通过一个简单的继电器电路接收信号，这不能监控断路或短路的连接线本身的状态。参照标准NAMUR(DIN EN50227，DIN192234)的其他水表电路能提供这种连接线的监控。这种电路规定将短路负载电阻并联接入簧片继电器上，而且将断路负载电阻串联接在簧片继电器上。当水表流量计采用这种电路时，不仅能计算簧片继电器闭合的次数，还能监控连接线在不同电流值下的断路和短路。既能连接具有继电器电路的水表，又能连接具有可测定电流量的电路以监控连接线的状态的水表的流量计电路是符合目的的，但不是所有的外围电子系统都能接具有可测定电流量的电路的水表。In addition, the pulse counter connected to the reed relay of the known water meter flowmeter receives the signal through a simple relay circuit, which cannot monitor the state of the connecting wire itself for open or short circuits. Other water meter circuits according to the standard NAMUR (DIN EN50227, DIN192234) can provide this monitoring of the connection line. This circuit provides for connecting a shorted load resistor in parallel to the reed relay and an open load resistor in series with the reed relay. When the water meter flow meter adopts this circuit, it can not only count the number of times the reed relay is closed, but also monitor the open circuit and short circuit of the connecting wire at different current values. It is desirable to be able to connect a water meter with a relay circuit and a flow meter circuit with a circuit that can measure the current to monitor the state of the connection line, but not all peripheral electronic systems can be connected with a current that can be measured. Water meter for the flow circuit.
已知这种水表电路能发出因外部磁影响而导致流量计数闭塞的信号(EP1039270A1，国际分类号G01F15/06，2000)。Such water meter circuits are known to signal flow count occlusion due to external magnetic influences (EP1039270A1, International Classification No. G01F15/06, 2000).
已知这种水表电路包括一个串联连接的计数常开簧片继电器，所述簧片继电器安装在非磁性材料制成的表体内，能与永磁体产生周期性磁反应，所述永磁体偏心固定在能圆周转动并进行闭合-断开循环的轮上，所述轮与水表表体通道内的叶轮传动连接，还包括一个短路负载电阻，两根水表电路导线，其中一根接在计数常开簧片继电器上，而另一根根导线接在短路负载电阻上，以及包括磁反应信号常开簧片继电器和磁反应短路负载电阻相互并联在一起的组件，所述组件的一端接在短路负载电阻上(与负载电阻连接的导线上)，而另一端接在水表电路的另外的导线上。磁反应信号常开簧片继电器设置在其与永磁体产生反应的范围之外。Such water meter circuits are known to consist of a counting normally open reed relay connected in series, said reed relay mounted in a meter body made of non-magnetic material capable of producing a periodic magnetic reaction with a permanent magnet fixed eccentrically On the wheel that can rotate in a circle and perform closed-off cycles, the wheel is connected with the impeller in the channel of the water meter body, and also includes a short-circuit load resistor, two water meter circuit wires, one of which is connected to the counting normally open On the reed relay, and the other wire is connected to the short-circuit load resistor, and the components including the magnetic response signal normally open reed relay and the magnetic response short-circuit load resistor are connected in parallel with each other, and one end of the component is connected to the short-circuit load The resistor (on the wire connected to the load resistor), and the other end is connected to another wire of the water meter circuit. Magnetic Response Signal A normally open reed relay is set out of its range to react to a permanent magnet.
在这种已知的方案中可以提供水表闭塞的信号，但是这种已知水表电路需要有额外的导线连接到外围电子系统中，而且还不能根据上述标准进行统计。因此，也就不能用来连接根据上述提及的标准进行用水量统计的外围电子系统。In this known solution, the signal of water meter occlusion can be provided, but this known water meter circuit requires additional wires to be connected to the peripheral electronic system, and it cannot be counted according to the above-mentioned standard. Therefore, it cannot be used to connect peripheral electronic systems that perform water consumption statistics according to the above-mentioned standards.

具体实施方式Detailed ways
一种水表流量计，包括：A water meter flowmeter, comprising:
安装在表体1上的机械数字计数装置2，在同一轴线上设置有传动连接轮3，在轮的侧表面上有用来显示流量数值的数字；The mechanical digital counting device 2 installed on the meter body 1 is provided with a transmission connection wheel 3 on the same axis, and there are numbers used to display the flow value on the side surface of the wheel;
流量计磁性半联轴节4，所述半联轴节安装在表体1内，能转动而且与水表的支撑框架(图中没有显示)的配对半联轴节5(图2)有磁反应，所述配对半联轴节与叶轮6传动连接，叶轮设置在该支撑框架的通道内以便在流动水流中转动；The flowmeter magnetic half-coupling 4, said half-coupling is installed in the meter body 1, can rotate and has a magnetic reaction with the matching half-coupling 5 (Fig. 2) of the supporting frame of the water meter (not shown in the figure) , the paired half-couplings are in transmission connection with the impeller 6, and the impeller is arranged in the channel of the support frame so as to rotate in the flowing water flow;
将流量计磁性半联轴节4与机械数字计数装置2的主动轮8传动连接的齿轮组7；A gear set 7 that connects the magnetic half-coupling 4 of the flowmeter with the driving wheel 8 of the mechanical digital counting device 2;
偏心固定在机械数字计数装置2的主动轮8上的永磁体9；A permanent magnet 9 fixed eccentrically on the driving wheel 8 of the mechanical digital counting device 2;
水表电路接有(图3)：The water meter circuit is connected (Figure 3):
串联连接的计数常开簧片继电器10(G1)，所述计数常开簧片继电器安装在表体1内，当转动机械数字计数装置2的主动轮8能与永磁体9产生周期性磁反应从而进行闭合-断开循环；还接有短路负载电阻11(R2)；The counting normally open reed relay 10 (G1) connected in series, the counting normally open reed relay is installed in the meter body 1, when the driving wheel 8 of the mechanical digital counting device 2 is turned, it can generate a periodic magnetic reaction with the permanent magnet 9 Thereby, a closed-open cycle is performed; a short-circuit load resistor 11 (R2) is also connected;
两根水表电路导线12和13，其中一根导线接在计数常开簧片继电器10上，另一根导线接在短路负载电阻11上；Two water meter circuit wires 12 and 13, one of which is connected to the counting normally open reed relay 10, and the other wire is connected to the short-circuit load resistor 11;
断路负载电阻14(R1)，所述断路负载电阻接在与计数常开簧片继电器10和短路负载电阻11并联在一起的水表电路的导线12和13上；Open circuit load resistance 14 (R1), described open circuit load resistance is connected on the wire 12 and 13 of the water meter circuit connected in parallel with counting normally open reed relay 10 and short circuit load resistance 11;
一对串联在一起的磁反应信号常开簧片继电器15(G2)和磁反应负载电阻16(R3)，所述这对组件接在与计数常开簧片继电器10和短路负载电阻11并联在一起的水表电路的导线12和13上。A pair of magnetic response signal normally open reed relay 15 (G2) and magnetic response load resistor 16 (R3) connected in series, said pair of components connected in parallel with counting normally open reed relay 10 and short circuit load resistor 11 together on wires 12 and 13 of the water meter circuit.
鉴于水表流量计表体的形状，水表电路可以含有两对及两对以上类似的串联在一起的磁反应信号常开簧片继电器和磁反应负载电阻。这使得对水表闭塞的监控更为可靠和准确(上述每对组件都是由一个磁反应信号常开簧片继电器和一个磁反应负载电阻组成)。In view of the shape of the water meter flowmeter body, the water meter circuit can contain two or more pairs of similar magnetic response signal normally open reed relays and magnetic response load resistors connected in series. This makes the monitoring of water meter occlusion more reliable and accurate (each pair of components above consists of a magnetic response signal normally open reed relay and a magnetic response load resistor).
磁反应信号常开簧片继电器15设置在非磁材料制成的表体1内，并要在其与永磁体9磁场产生反应的范围之外。图4示出了这种设置形式的例子。The normally open reed relay 15 for the magnetic response signal is arranged in the watch body 1 made of non-magnetic material, and is outside the range in which it reacts with the magnetic field of the permanent magnet 9 . Figure 4 shows an example of such an arrangement.
断路负载电阻14的电阻值可以为5.6千欧，短路负载电阻11的电阻值为1千欧，而磁反应负载电阻16的电阻值为400欧。11、14和16的电阻值也可以与上述值不同。选择电阻值的条件为：断路负载电阻14的电阻值要大于短路负载电阻11的电阻值，依照顺序，短路负载电阻11的电阻值大于磁反应负载电阻16的电阻值。参照图5所示的线图，满足这个条件才能确保水表电路的工作，从图中可以看出，根据电流值能判断出水表的工作模式。接入参照本发明制成的水表电路的外围电子系统能够自动跟踪水表的工作模式。水表电流的导线12和13为从表体1引出的电缆17，所述电缆为放进一个整体的绝缘外皮内的两根绝缘导线。所述导线用来将水表电路接到外围电子系统上。由于在机械数字计数装置2的主动轮8上设置了永磁体9，可以确保产生的脉冲与机械数字计数装置2的工作同步，这样就简化了调试，并能监控流量统计系统的工作。The resistance value of the open circuit load resistor 14 can be 5.6 kΩ, the resistance value of the short circuit load resistor 11 is 1 kΩ, and the resistance value of the magnetic response load resistor 16 is 400 Ω. The resistance values of 11, 14 and 16 can also be different from the above-mentioned values. The condition for selecting the resistance value is: the resistance value of the open-circuit load resistor 14 is greater than the resistance value of the short-circuit load resistor 11 , and in sequence, the resistance value of the short-circuit load resistor 11 is greater than the resistance value of the magnetic response load resistor 16 . Referring to the line diagram shown in Figure 5, only by satisfying this condition can the water meter circuit work. It can be seen from the figure that the working mode of the water meter can be judged according to the current value. The peripheral electronic system connected with the water meter circuit manufactured by referring to the invention can automatically track the working mode of the water meter. The wires 12 and 13 of the water meter current are cables 17 drawn from the meter body 1, and the cables are two insulated wires put into an integral insulating sheath. The wire is used to connect the water meter circuit to the peripheral electronic system. Since the permanent magnet 9 is set on the driving wheel 8 of the mechanical digital counting device 2, it can ensure that the generated pulse is synchronized with the operation of the mechanical digital counting device 2, which simplifies debugging and can monitor the work of the flow statistics system.
上述所列实施例并非穷举。本发明还包括其他可能的实施例。根据本发明制成的水表流量计及其电路的所有零件都是使用日常材料，根据传统的已知工艺制成。The examples listed above are not exhaustive. The invention also includes other possible embodiments. All parts of the water meter flowmeter and its circuit made according to the present invention are made according to conventional known techniques using common materials.
