Description
Technical field
The present invention relates to water meter device field, particularly relate to a kind of impeller box with regulatory function.
Background technology
At present, urbanite water consumption table majority is that water promotes impeller to rotate the cumulant measuring urbanite water consumption, i.e. rotor water gauge.Water meter can be divided into positive displacement and rotary wind type, and positive displacement is wait measurement, and the rotating speed that rotary wind type is the speed according to current and impeller realizes indirect measurement.Rotor water gauge can be divided into dry type and wet type, rotary-wing type wet water-meter is connected on water supply line, the gland on housing and its top forms volume, connecting portion between fluid intake and outlet is housing, and its top is enumerator, and bottom is impeller box, impeller box has impeller and lower shaft, impeller box upper and lower end all has many holes, below be blasthole, above be apopore.Impeller axle in impeller box is connected with the armature spindle of enumerator, and water is entered by blasthole and promotes wheel rotation in impeller box so that it is driven gear rotates the cumulant that can show water.And water can not impeller rotate by after inlet opening entrance impeller box, if current are only small, so the big wheel rotation that could promote of flow, namely initial-flow is big；And the big low discharge error robustness that affects of initial-flow, so Running-water Company's water supply can be caused many and user's water meter the shows little situation that there is error instability of numeral, water supply company is existed inequitable phenomenon.
Applicant has applied for a kind of adjustable water meter of highly sensitive error a few days ago, the patent No.: 2013107550559, it discloses a kind of adjustable water meter of highly sensitive error, including water meter case, described water meter case is provided with character wheel box, described character wheel and be installed below impeller box, described impeller box is provided with impeller, on described impeller box, multiple apopores that lower end is offered respectively and inlet opening, side, described inlet opening is provided with baffle plate, described baffle plate top is connected with screw rod, coordinate with the thread bush being fixed on impeller box in the middle part of described screw rod, the top of described screw rod is provided with knob, described screw rod and knob extend to outside water meter case.Water inlet at impeller box arranges the baffle plate that can regulate, it is possible to controls current and enters into the flow in impeller box, such that it is able to water meter is finely tuned, reduces the error of water meter.The shortcoming of this kind of structure is, the paddle hole of this water meter is arranged on the side of impeller box, baffle plate moves up and down at water inlet, there is no limiting component, only by screw support, owing to current often very big long-time use of water inlet will will go out gap between baffle plate and impeller box, cause the situation that metering is inaccurate.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned technology, and a kind of impeller box with regulatory function be provided, adjustable plate long-time current scour will not displacement, improve metering accuracy.
The present invention is for achieving the above object, by the following technical solutions: a kind of impeller box with regulatory function, it is characterized in that: include impeller box, adjustable plate, metering plate and fixing plate, the bottom of described impeller box is provided with current baffle plate, it is provided with supported hole between wherein two pieces adjacent current baffle plate, being provided with described fixing plate with described supported hole to corresponding impeller box, described fixing plate is respectively equipped with installing hole and fixing hole, described installing hole is with described support hole on the same axis；Described metering plate side is fixed with adjustment axle, described adjustable plate is placed between adjacent current baffle plate, described adjustment axle sequentially passes through described installing hole and described adjustable plate, the front end regulating axle is inserted in described supported hole, described metering plate is provided with regulating tank, and screw is connected through described regulating tank with the fixing hole on described fixing plate.Relative to prior art, the impeller box of the present invention is from bottom water outlet, and split current with polylith baffle plate, current can be made more uniform, between two adjacent current baffle plates, adjustable plate is set, current can be carried out fine adjustments by adjustable plate, adjustable plate connects metering plate, metering plate is fixed on Gu Banshang by adjusting bolt, when needing to regulate, unclamp adjusting bolt, pull metering plate, metering plate rotates and drives adjustable plate to rotate, it is thus possible to trickle adjustment current, control water meter precision, after adjustment completes, tighten again into bolt, adjustable plate and metering plate are all tightly fastened, fixation, shifting phenomena will not occur due to washing away of current.
Preferably, described metering plate is provided with keyhole, and the front end of described metering plate is provided with pointer.The angle that metering plate rotates can be regulated, it is simple to operation by inserting flat-shaped key at keyhole.Pointer can make workman record the position of adjustment.
Preferably, described fixing plate is provided with graduation mark, and described pointer is corresponding with described line of weakness.It is easy to record it is known that the rotational angle of adjustable plate.
Preferably, the middle part of described adjustment axle is both sides is flat, and front portion is cylindric.Middle part flat can be fixed closely with adjustable plate, it is prevented that adjustable plate is regulating rotation on axle, and front portion is cylindric can be rotatably assorted with supported hole.
The invention has the beneficial effects as follows: present configuration is simple, relative to prior art, the impeller box of the present invention is from bottom water outlet, and split current with polylith baffle plate, current can be made more uniform, between two adjacent current baffle plates, adjustable plate is set, current can be carried out fine adjustments by adjustable plate, adjustable plate connects metering plate, metering plate is fixed on Gu Banshang by adjusting bolt, when needing to regulate, unclamp adjusting bolt, pull metering plate, metering plate rotates and drives adjustable plate to rotate, it is thus possible to trickle adjustment current, control water meter precision, after adjustment completes, tighten again into bolt, adjustable plate and metering plate are all tightly fastened, fixation, shifting phenomena will not occur due to washing away of current.
