Abstract
The utility model belongs to a single flow beam water meter, which particularly relates to a high-sensitivity single flow beam water meter as a measuring device used for measuring the total volume of water flowing through a water supply pipeline. The utility model is characterized in that the design of the shape of a water inlet hole of an outer shell of a water meter is improved, the shape of the water inlet hole of the outer shell of the water meter is in a conical shape, the pore diameter of the water inlet hole is from large to small in a water flow direction, and an angle alpha between 15 DEG and 35 DEG is formed between the axial line of the water inlet hole and the axial line between an inlet and an outlet of the water meter. Water flow can form a jet state, transmission pressure is increased, the pressure of the water flow impacting an impeller is increased, the impeller can be pushed to rotate continuously in order to drive a gear of a reading device of the water meter to rotate, and the sensitive needle pointer of the water meter can rotate. The high-sensitivity single flow beam water meter of the utility model realizes the measurement of the water having tiny flow of the water meter, the maximum sensitivity can reach 1-2 L per hour, the sensitivity of the single flow beam water meter is enhances completely, the water consumption of a user is displayed accurately, the loss of water quantity is prevented, and the waste of water resources is avoided.
Description
Technical field the utility model belongs to the single channel water meter, particularly a kind of measurement instrument that is used for measurement flow through the volume total amount of water supply pipe water---high sensitivity single channel water meter.
The existing tap water water meter of background technology is when tiny flow quantity current process water meter, and the sensitivity pointer of water meter does not rotate and do not measure.At present, both at home and abroad single channel B level watermeter flowing rate＞8 of adopting liter/hour, single channel C level surface low amount＞4 liter/hour, the sensitivity pointer of water meter is rotation continuously.Because existing water meter inlet opening is isometrical, pressure is isobaric the transmission, hydraulic pressure equals water inlet pressure, the insufficient pressure of water impact impeller when tiny flow quantity, torsional moment is less than impeller stiction, the water meter main impeller can't rotate, and the gear that can not drive the reading device of water meter rotates, so water meter can't measure the water yield of the water meter of flowing through this moment.The sensitivity of tap water water meter is low, causes the metering numerical value of water meter and actual used water amount not to be inconsistent, and can not reflect water consumption exactly.Chinese patent 00136547.9 is disclosed to be a kind of anti-leakage intelligent watermeter, it is the anti-leakage intelligent watermeter of handling by Single-chip Controlling, by housing, seal pad, big water delivering orifice, signal hop, pressure spring, drive link, piston, water clock water hole, upper press cover, O-ring seal, sleeve etc. partly form, be characterized in that water water meter when water clock still can count, have cost height, complex structure, be difficult for implementing.
The summary of the invention the purpose of this utility model is for solving single channel water meter non-metering technical matters when the tiny flow quantity current pass through water meter, a kind of high sensitivity single channel water meter being provided.
The utility model high sensitivity single channel water meter content Description:
The utility model high sensitivity single channel water meter, it is characterized in that: be improvement watermeter shell inlet opening shaped design, the watermeter shell inlet opening be shaped as taper, descending in the water (flow) direction aperture, its axis and water meter import and export axis are ° angle, α=15～35, make current form the jet state, increase and transmit pressure, thereby increased the pressure of water impact impeller, can promote the impeller rotation, drive the gear rotation of meter reading device, the sensitivity pointer of water meter is rotated continuously.
The utility model high sensitivity single channel water meter has been realized the metering of water meter to tiny flow quantity water, and it is highly sensitive, sensitivity can reach 1～2 liter/hour, has thoroughly improved the sensitivity of single channel water meter, accurate response user's water consumption, prevent the loss of the water yield, avoided the waste of water resource.
