The water meter comprises a measuring mechanism, a bottom shell, an upper cover, a dial, a pointer, a transmission gear, a photosensitive sensor, a head lamp, a control device and a multilayer filter net. The measuring mechanism is arranged in the bottom shell, a glass cover is arranged between the upper surface of the bottom shell and the measuring mechanism, the dial is arranged between the measuring mechanism and the glass cover, the pointer and the transmission gear are arranged on the dial, the photosensitive sensor and the head lamp are arranged between the dial and the glass cover and fixedly connected with the dial, and the multilayer filter net is arranged at the water inlet end of the water meter. The photosensitive sensor is sequentially and electrically connected with the control device and the head lamp, the multilayer filter net is additionally arranged to filter media, and the service life of the water meter is prolonged; the photosensitive sensor and the control device are arranged, the photosensitive sensor converts optical signals into electric signals, and when light is insufficient, the control device controls the head lamp to turn on, and data can be conveniently read.
Description
Technical field
The invention belongs to measurement instrument technical field, particularly relate to a kind of water meter with filtering function.
Background technology
Measure the instrument of discharge.Divide by measuring principle: (1) velocity type water meter: be arranged in closed conduct, be made up of a motor element, 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.Single channel water meter and multistream water meter is had again in rotor water gauge.2) volumetric water meter: install in the duct, is successively full of with the room of the known volume of exhaust fluid by some and is relied on the water meter that forms of fluid-operated mechanism, or being called for short quantitative emission type water meter.Volumetric water meter generally adopts piston cylinder operator level can be divided into install water meter and vertical installation water meter by installation direction component velocity formula water meter, in national standard, velocity type water meter is defined as " be arranged in closed conduct; be made up of a dynamical element, and directly make it obtain a kind of water meter of motion by water flow velocity ".When current are by water meter, drive impeller (rotor or the spiral shell wing) rotates, and the flow velocity of current is directly proportional to the rotating speed of impeller, because the sectional area of current drive impeller place spout is constant, therefore the rotating speed of impeller is also directly proportional to flow, be connected with counting mechanism by the linkage part on impeller axle, make the revolution of counting mechanism accumulation impeller (rotor or the spiral shell wing), thus the water yield write down by water meter, because water meter is measuring instrument, generally be arranged in the corner of plant building or the corridor of resident, not only be convenient to check but also do not affect work and life, just because of this reason, the Spatial General 6 R installing water meter is narrower and small, and light is bad, depending on counting the smudgy of change, easily misread, if the impurity in water is too much, water meter is easily made to damage, the serviceable life of water meter is reduced.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of water meter with filtering function, 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, 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 successively with described control device, illuminating lamp.
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 and arrange projection on described, described projection and described groove clamping.
Described illuminating lamp ring is located at the side of described pointer.
The material of described bed filtration net is chromium NiTi cast steel-teflon.
Beneficial effect of the present invention is: the present invention arranges bed filtration net in the water inlet of valve, and the bore of bed filtration net is set to reduce gradually along water (flow) direction, this method filter effect is better, makes the liquid flowing through valve purer, extends the serviceable life of valve; By arranging light sensor between index dial and cloche, control device being set in housing, by light sensor, light signal being converted into electric signal, the keying of illuminating lamp is controlled by control device, when light is darker, control device controls illuminating lamp and opens, and facilitates reading; By arranging shading pad at the upper surface of drain pan, drain pan upper surface arranges groove, above covers and arranges projection, makes upper cover and housing compact siro spinning technology by protruding with groove, when upper cover is closed, can ensure that inner is complete lucifuge, extend the serviceable life of light sensor.
