Description
Technical field
The utility model belongs to measurement instrument technical field, relates in particular to a kind of anti-freeze water meter.
Background technology
Measure the instrument of discharge.By measuring principle, divide: (1) velocity type water meter: be arranged in closed conduct, by a motor element, formed, and directly make it obtain the water meter of dynamic speed by water movement speed.Typical velocity type water meter has rotor water gauge, helical vane type water meter.In rotor water gauge, there are again single channel water meter and multistream water meter.2) volumetric water meter: be arranged in pipeline, be successively full of and the room of the known volume of exhaust fluid and the water meter that relies on fluid-operated mechanism to form by some, or be called for short quantitative emission type water meter.Volumetric water meter generally adopts piston cylinder operator can be divided into level by installation direction component velocity formula water meter water meter and vertical installation water meter is installed, in national standard, velocity type water meter is defined as " be arranged in closed conduct; a dynamical element, consist of, and directly make it obtain a kind of water meter of motion by water flow velocity ".When current pass through water meter, drive impeller (rotor or the spiral shell wing) rotation, and the flow velocity of current and the rotating speed of impeller are directly proportional, because the sectional area of current drive impeller place spout is constant, therefore the rotating speed of impeller is also directly proportional to flow, by the linkage part on impeller shaft, be connected with counting mechanism, make the revolution of counting mechanism accumulation impeller (rotor or the spiral shell wing), thereby write down the water yield by water meter, because water meter is measuring instrument, generally be arranged in the corner of plant building or resident's corridor, work and life be not only convenient to check but also had not been affected, just because of this reason, the Spatial General 6 R that water meter is installed is narrower and small, and light is bad, what depending on number, become is smudgy, easily misread, if the impurity in water is too much, easily make water meter damage, reduced the serviceable life of water meter, when temperature is too low, the water capacity is easily solidified, the water capacity of condensing easily causes the loss of measurement structure.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of anti-freeze water meter, comprise metering mechanism, drain pan, upper cover, index dial, pointer, transmission gear, described metering mechanism is arranged in described drain pan, between described drain pan upper surface and described metering mechanism, cloche is set, between described metering mechanism and described cloche, index dial is set; Described pointer and transmission gear are arranged on described index dial; Described drain pan and described upper cover chain connection, characterized by further comprising light sensor, control device, illuminating lamp, bed filtration net, temperature sensor, treating apparatus, heating arrangement, and described bed filtration net and water inlet position pipeline removably connect; The aperture of described bed filtration net reduces gradually along water (flow) direction; Described light sensor, illuminating lamp are all arranged between described index dial and cloche, are fixedly connected with index dial; Described light sensor is electrically connected to successively with described control device, illuminating lamp, and described temperature sensor is arranged in described drain pan; Described heating arrangement is arranged on the outside surface of described drain pan; The arranged outside collet of described heating arrangement.。
The upper surface of described drain pan is provided with shading pad, and described shading pad is annular.
Described drain pan upper surface arranges groove, covers on described and projection is set, described projection and described groove clamping.
Described illuminating lamp ring is located at a side of described pointer.
The material of described bed filtration net is chromium NiTi cast steel-teflon.
The beneficial effects of the utility model are: the utility model passes through at enclosure interior set temperature sensor, the electrical signal transfer transforming to treating apparatus after, after treating apparatus is analyzed, the heating of control heating arrangement, thereby guarantee the normal operation of water meter, the utility model is applicable to being adapted at the place that temperature is lower to be used; In the water inlet of valve, bed filtration net is set, and the bore of bed filtration net is set to reduce gradually along water (flow) direction, this method filter effect is better, and the liquid of the valve that makes to flow through is purer, extends the serviceable life of valve; By light sensor being set between index dial and cloche, control device is set in housing, by light sensor, light signal is converted into electric signal, by control device, control the keying of illuminating lamp, when light is darker, control device is controlled illuminating lamp and is opened, and facilitates reading; By the upper surface at drain pan, shading pad is set, drain pan upper surface arranges groove, above covers projection is set, and by projection, with groove, upper cover is closely connected with housing, and when upper cover is closed, can guarantee inner is complete lucifuge, extends the serviceable life of light sensor.
