Abstract

A two-way water meter. It is mainly composed of shell, surface, impeller and gear set. The utility model is characterized in that: two-way measurement, the surface is digital or pointer type, which can visually display the water in and out. The utility model has the advantages of conveniently and accurately displaying the water inflow and outflow, accurate measurement, convenient reading and simple structure, and is especially suitable for places where the water inflow and outflow need to be known, such as solar water heaters.

Description

Two-way water meter

本实用新型设及一种水表。The utility model relates to a water meter.

传统水表都是单向计量，即按水表上标明的进水方向安装水表则可计量进水多少，但不能计算出水量。在需要既要计算进水量又要计算出水量的地方，传统水表就不能使用。Traditional water meters are all one-way measurement, that is, installing a water meter according to the water inlet direction marked on the water meter can measure the amount of water inflow, but cannot calculate the amount of water out. Where it is necessary to calculate both the inflow and outflow of water, traditional water meters cannot be used.

本实用新型的目的是提供一种能够方便、准确地显示进、出水量的双向计量水表。The purpose of the utility model is to provide a two-way measuring water meter which can conveniently and accurately display the water inflow and outflow.

本实用新型是这样实现：本实用新型包括壳体、表面、叶轮和齿轮组。叶轮安装在壳体的下部；齿轮组安装在叶轮上面，叶轮的轴齿轮和齿轮组中的一个齿轮接触并可带动其转动；表面安装在壳体上部，表面上的指针或数字轮和齿轮组中的一个齿轮输出轴相连，齿轮转动带动指针或数字轮转动。其特征在于：双向计量，表面是数字型或指针型，能够直观地显示进水量和出水量。The utility model is achieved in that the utility model comprises a housing, a surface, an impeller and a gear set. The impeller is installed in the lower part of the housing; the gear set is installed on the impeller, and the shaft gear of the impeller contacts with a gear in the gear set and can drive it to rotate; the surface is installed in the upper part of the shell, and the pointer or number wheel and the gear set on the surface One of the gear output shafts is connected, and the rotation of the gear drives the rotation of the pointer or the digital wheel. It is characterized in that: two-way metering, the surface is digital or pointer type, which can intuitively display the water inflow and outflow.

图1为本实用新型的俯视图；Fig. 1 is the top view of the utility model;

图2为本实用新型的剖视图。Fig. 2 is a sectional view of the utility model.

下面结合附图作进一步说明：参照附图1-2，图中1为壳体，2为表面，3为叶轮，4为齿轮组，5为复零旋扭。工作原理为当水流通过水表时推动叶轮3，带动齿轮组4转动，指针或数字将进水量显示在表面上；当水流反向通过时，同理，水表显示流出水量。复零旋扭5按下后其轴端伞齿轮和齿轮组中的一个齿轮接触，可调节齿轮转动达到复零目的，在进出水量有误差时使用。Further explanation is made below in conjunction with accompanying drawing: with reference to accompanying drawing 1-2, among the figure 1 is casing, and 2 is surface, and 3 is impeller, and 4 is gear set, and 5 is reset zero twist. The working principle is that when the water flow passes through the water meter, the impeller 3 is pushed to drive the gear set 4 to rotate, and the pointer or number displays the water inflow on the surface; when the water flow passes in the opposite direction, the water meter displays the outflow water in the same way. After the zero reset knob 5 is pressed, its shaft end bevel gear contacts with a gear in the gear set, and the adjustable gear rotation reaches the zero reset purpose, which is used when there is an error in the amount of water in and out.

本实用新型的优点是：能够双向显示水量，计量准确，识读方便，结构简单，特别适用于需知其进出水量的地方，如太阳能热水器上。The utility model has the advantages of bidirectional display of water volume, accurate measurement, convenient reading and simple structure, and is especially suitable for places where the water in and out of the utility model needs to be known, such as solar water heaters.
