Abstract
The utility model provides a water meter which solves the problem that reverse installation causes the water meter to lose metering function. The utility model is characterized in that the water inlet port of the water meter is provided with a one-way stop valve. Due to the adoption of the one-way stop valve, water can only flow in a one-way direction, and thus measuring accuracy is ensured.
Description
Technical field: the utility model relates to a kind of water meter.
Background technology: the water meter that uses is made up of watch shell and built-in rotor gear and digital indicating device at present, need only during installation by the installation of the arrow indicating correct on the housing and just can measure, but, will make water meter counter-rotating if install in the other direction, thereby cause measuring distortion as a result, lose the function of measuring of water meter.In addition,, can make that also water meter is ineffective, can't measure that promptly when water drop by drop flowed, water meter just can not rotate when the flow velocity of water is very little to can't promote the rotor gear time.
Summary of the invention: the utility model proposes a kind of water meter in order to solve water meter and can oppositely to install and the water meter that causes loses the problem of function of measuring, and it is characterized in that: the water inlet port of described water meter is provided with unidirectional stop valve.Owing to adopted unidirectional stop valve, thereby make that water can only the way flow mistake, guaranteed the accuracy of metering; Simultaneously because the existence of unidirectional stop valve, when minimum velocity very, unidirectional stop valve also can't be opened, also the non-metering problem of water meter when having overcome water and drop by drop flow.
Description of drawings: Fig. 1 is the utility model structural representation.
Embodiment: as shown in Figure 1, this water meter is mainly shown body 1, unidirectional stop valve 2 is formed.When current during along forward flow, current promote table body 1 built-in rotor gear and rotate, and drive the pointer rotation, realize correctly metering; If when oppositely installing, unidirectional stop valve 2 ends, the rotor gear stops operating, and pointer is motionless, has promptly reached to prevent oppositely installation or adopt fine water drip water to carry out the purpose of stolen water.
