Description
Technical field
The utility model relates to a kind of paddle wheel flowmeter of measuring discharge.
Background technology
The principle of work of paddle wheel flowmeter is that current flow into through wheel set assembly from water-logged base, flow out from effluent seat again, the speed of runner rotational speed is the flow that is decided by water, magnet in the wheel set assembly is arranged in the wheel set assembly, so runner rotates a circle, also revolve and turn around with regard to driving magnet in the wheel set assembly, the Hall components and parts in the sensor pulse signal circuit output precision just receive signal one time, and outwards send signal one time.
The flowmeter that tradition is used to measure discharge generally is not provided with dividing plate in the current through hole of water-logged base, act directly on the runner behind the current process water-logged base through hole during flowmeter work, the drive runner rotates, because the flow rate of water flow faster or slower of process, flow varies, therefore can't guarantee that current act on the consistance of the current frequency on the runner behind process water-logged base through hole, and when water flow is excessive, because of the power that acts on the runner causes all directions, cause runner all stressed and drive runner and clockwise rotate and runner can't be rotated when identical probably with the power that rotates counterclockwise because of all directions; Same runner does not rotate because of the power that is subjected to is too small when water flow is too small, and current directly flow out effluent seat, cause flowmeter can't measure the frequency of the current of low discharge.
The water-logged base of paddle wheel flowmeter in the market and effluent seat generally all are that a end with effluent seat directly inserts in the cavity of water-logged base in addition, with the screw more than two pieces or two pieces that the both ends of the surface that effluent seat and water-logged base offset are locked.Though such structure can play the secure fit effect with water-logged base and effluent seat locking, is difficult for installation and removal.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of paddle wheel flowmeter that mounts and dismounts more convenient and energy measurement than the low discharge frequency.
For achieving the above object, the utility model provides a kind of paddle wheel flowmeter to comprise the flowmeter shell, wheel set assembly, sensor pulse signal circuit output precision, the flowmeter shell comprises water-logged base and effluent seat, water-logged base and effluent seat are the plug-in type secure fit, be provided with seal assembly between water-logged base and the effluent seat, the end face that water-logged base and effluent seat offset is provided with cavity, be provided with the water-logged base through hole that the stream that can supply water passes through in the cavity, effluent seat is provided with the boss of closely pegging graft and cooperating with the water-logged base cavity with the end face that water-logged base offsets, be provided with the effluent seat through hole that the stream that can supply water passes through in the boss, wheel set assembly is arranged in the water-logged base through hole, and offset with boss that effluent seat inserts the water-logged base cavity, sensor pulse signal circuit output precision is arranged on the water-logged base shell, the axial symmetrical both sides of the both ends of the surface that described effluent seat and water-logged base offset are respectively arranged with elongated end, both ends of the surface elongated end one side that effluent seat and water-logged base offset is respectively arranged with projection, two projections are provided with can be for the screw of screw lock, the both ends of the surface elongated end that effluent seat and water-logged base offset the axially opposite side of symmetry is respectively arranged with lug, and the lug of effluent seat end face extends to water-logged base lug direction, be provided with the groove that can hold the water-logged base lug in the elongated end of the lug of effluent seat end face, the described groove that holds the water inlet end lug one side closed.
The water-logged base through-hole wall is provided with some dividing plates of cutting apart the water-logged base through hole, and the cross sectional dimensions size that the water-logged base through hole is cut apart some water flow passage that the back forms by some dividing plates is inequality.
The beneficial effects of the utility model are: owing to be provided with some dividing plates in the through hole of water-logged base, and some water flow passage while inflows that the water-logged base through hole is cut apart back formation by some dividing plates are inconsistent, so having guaranteed current acts on the runner after through the water-logged base through hole, drive the continuation of the power of runner rotation, therefore also just guaranteed the consistance of runner rotational frequency.Simultaneously when water flow is excessive, inflows are inconsistent simultaneously because of the water-logged base through hole is cut apart the back some water flow passage that form by some dividing plates, so also clockwise rotate identical with the power that rotates counterclockwise and situation that runner can't be rotated with regard to current drive runner not occurring; It is same when water flow is too small, because of being provided with dividing plate in the water-logged base through hole, thereby make current can directly not flow to the through hole outflow effluent seat of effluent seat from the through hole of water-logged base, rotate but drive runner from the blade of the runner of flowing through earlier after the through hole of water-logged base is flowed through dividing plate, flowing out effluent seat at last, so also just guaranteed the measurement of flowmeter, further improved the precision of flowmeter survey to less water flow.
The paddle wheel flowmeter that provides of the utility model is that a end with the effluent seat of flowmeter directly inserts in the cavity of water-logged base in addition, then will by the rotation, the lug of water-logged base is stuck in the groove of lug elongated end of effluent seat, by one piece of screw the both ends of the surface that water-logged base and effluent seat offset are being locked, such secure fit mode is easy to installation and removal, also reduce simultaneously the use of screw, provided cost savings and saved the repeatedly loaded down with trivial details manufacturing procedure of boring.
The boss circumferential surface that the utility model can further be set to described effluent seat insertion water-logged base is provided with the some grooves that can place seal assembly.
The utility model can further be set to described wheel set assembly and comprise axle bed, rotating shaft, runner, rotor cap, magnet, axle bed is located in the water-logged base through hole, and offset with boss that effluent seat inserts the water-logged base cavity, be provided with the axis hole that is rotatably assorted with rotating shaft in the axle bed, rotaring wheeling sleeve is connected in the rotating shaft, and the runner end face is provided with boss, be provided with cavity in the boss, magnet is located in the cavity of runner boss, and the rotor cap sleeve is connected on the runner boss, and constitutes the sealing to cavity on the runner boss.
