The valve core is suspended in the valve body through a single-side rotating support. The utility model provides a case is rotatory steady, output signal is steady accurate, bearing wear is even, life improves flow detection valve.
Description
(1) technical field
The utility model relates to a kind of flow rate measurement valve.
(2) background technology
Flow rate measurement valve has two kinds of side valve type and rotary valves, the former slides in valve body by spool, magnet is housed on the spool, but an end of valve body is installed the displacement transducer of induced magnet change in location, such as Hall element, under the impact of fluid, spool moves in valve body, its displacement reflection flow size obtains flow by the displacement that detects spool; Latter's rotary valve, spool is to rotate in valve body, the one end sealing of valve body, the other end is a fluid egress point, and fluid intake is arranged on side of valve body, and spool passes through the Bearing Installation at two ends in valve body, the outside surface of rotor has blade, magnet is installed on the rotor, and pulse transducer (such as incremental encoder) is installed in position corresponding on the valve body, and the interior magneto sensor of the installation direction of magnet and pulse transducer cooperates.Spool drives the magnet rotation during work, produces the changes of magnetic field that the N utmost point and the S utmost point replace, and pulse transducer can detect the numerical values recited of pulse in real time, produces electric signal, and discharge can be detected in real time.
The deficiency that above-mentioned rotary valve flow rate measurement valve exists is: because fluid intake is arranged on side of valve body, when the fluid impact spool, the spool both sides are subjected to force unbalance, spool can be to the side extruding away from fluid intake, make that the rotation supporting part at two ends is more serious at this lateral wearing, influence serviceable life; After the rotation supporting part wearing and tearing, the spool rotation owes steadily, can influence the stationarity and the accuracy of sensor output signal like this.
(3) summary of the invention
In order to solve the above-mentioned deficiency of existing flow rate measurement valve, the utility model proposes the rotation of a kind of spool steadily, output signal exactly, rotation supporting part wearing and tearing evenly, serviceable life the flow rate measurement valve that improves.
A kind of flow rate measurement valve, comprise valve body, one end of described valve body is provided with fluid egress point, spool is installed in rotation in the valve body, the outside surface of spool has moving blade, magnet is housed on the spool, pulse transducer is equipped with in position corresponding with magnet on the valve body, magneto sensor in the installation direction of described magnet and the pulse transducer cooperates, it is characterized in that: the other end of described valve body is provided with fluid intake, block is equipped with at the center of described fluid intake, constitutes the opening around shape between the periphery of described block and the inwall of fluid intake.
Further, described spool is suspended in the valve body by one-sided rotation supporting part.
Preferably, constitute uniform annular opening between the inwall of the periphery of described block and fluid intake.
As preferably: on the described fluid egress point locating piece is housed, guide rod is installed on the locating piece, described spool is sleeved on the guide rod rotationally by guide pin bushing.
Perhaps, described one-sided rotation supporting part is a bearing.
Preferably, constitute uniform ring exit between the inwall of the periphery of described locating piece and described fluid egress point.
Technical conceive of the present utility model is: flow axis is to water inlet, flow into from annular opening, the centre is stopped by block, current only impact blade, resistance to water-flow is little, the promotion moving blade made the spool rotation after the accuracy that detects in the time of can improving weep, fluid entered valve body, and fluid is flowed out by the ring exit around the locating piece.For fluid intake was arranged on the valve body sidepiece, the annular opening that is arranged on valve end made spool stressed more balanced, rotate also more steady, thereby the metering result of sensor exactly more; The rotation supporting part wearing and tearing evenly the situation that uneven wear influences the life-span can not occur.
Spool is suspended in the valve body by one-sided rotation supporting part, can save part.
The beneficial effects of the utility model are: the rotation of (1) spool is steady, and signal of sensor is exactly more; (2) even, the raising in serviceable life of rotation supporting part wearing and tearing; (3) resistance to water-flow is little, accuracy in detection height during low discharge; (4) save part, save cost.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment one
With reference to accompanying drawing: a kind of flow rate measurement valve, comprise valve body 1, one end of described valve body 1 is provided with fluid egress point 2, spool 3 is installed in rotation in the valve body 1, the outside surface of spool 3 has moving blade, magnet 4 is housed on the spool 3, pulse transducer 5 is equipped with in position corresponding with magnet 4 on the valve body 1, magneto sensor in the installation direction of described magnet 4 and the pulse transducer 5 cooperates, the other end of described valve body 1 is provided with fluid intake 6, block 7 is equipped with at the center of described fluid intake 6, constitutes uniform annular opening 8 between the inwall of the periphery of described block 7 and fluid intake 6.
Described spool 3 is suspended in the valve body by one-sided rotation supporting part.Particularly, locating piece 10 is housed on the described fluid egress point, guide rod 11 is installed on the locating piece 10, described spool 3 is sleeved on the guide rod 11 rotationally by guide pin bushing 12.Constitute uniform ring exit 9 between the inwall of the periphery of described locating piece 10 and described fluid egress point 2
During use, valve body is vertically installed, flow axis is to water inlet, flow into from annular opening, the centre is stopped that by block current only impact blade, resistance to water-flow is little, the promotion moving blade made the spool rotation after the accuracy that detects in the time of can improving weep, fluid entered valve body, and fluid is flowed out by the ring exit around the locating piece.For fluid intake was arranged on the valve body sidepiece, the annular opening that is arranged on valve end made spool stressed more balanced, rotate also more steady, thereby the metering result of sensor exactly more; Wearing and tearing evenly the situation that uneven wear influences the life-span can not occur between guide rod and the guide pin bushing.Spool is suspended in the valve body by one-sided rotation supporting part, can save part.
The streamlined flow of water has produced rotatablely moving of spool, and spool drives magnet and rotates, and produces the changes of magnetic field that the N utmost point and the S utmost point replace, and pulse transducer can detect the numerical values recited of pulse in real time, produces electric signal, makes discharge can show detection in real time.
