Technical field
The utility model relates to valve and fluid metering technical field, relates in particular to a kind of supersonic wave metering butterfly valve.
Background technology
Butterfly valve is a kind of control valve simple in structure, the butterfly valve that can be used for the switch control of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, rotate to reach a kind of valve of open and close around valve shaft, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium. On pipeline, main rising cut off and throttling action. Butterfly valve opening and closing element is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the object that opens and closes or regulate.
At present, most of butterfly valves are only used as the flow direction that cuts off, ends and change fluid in fluid circuit, but along with the development of valve industry, the function of dish valve is more and more difficult to meet the demand in market. In existing pipeline, valve and the flowmeter overwhelming majority are installed separately, and need to vacate the straight length of certain length or adopt other constant-current stabilizers before and after the pipeline that flowmeter is installed, and when needing again dish valve and flowmeter are installed simultaneously on short pipeline, often be difficult to realize or engineering has been proposed to high requirement, adopt this mounting means also to need more pipe well for later maintenance, not only greatly increased construction costs and labour cost, and maintenance cost is also higher. On the other hand, install while needing to install flowmeter additional again on the pipeline of dish valve, buried pipeline need to have been dug out, after disconnecting, increased attaching parts, as flange, so that flowmeter is increased in pipeline, great in constructing amount, journey difficulty is large and costly.
Utility model content
The purpose of this utility model is exactly will overcome existing most of butterfly valve in fluid circuit, to be only used as the flow direction that cuts off, ends and change fluid, in pipeline, valve and the flowmeter overwhelming majority are the problems being installed separately, a kind of supersonic wave metering butterfly valve is provided, the valvular function of its tool, again measurable flow body flow and not affected by liquid, certainty of measurement is high, long service life, feature simple in structure, convenient for installation and maintenance.
For achieving the above object, the supersonic wave metering butterfly valve that the utility model is designed, comprises valve body, is located at the butterfly plate in valve body, the valve rod that drives butterfly plate to rotate; On described butterfly plate, be embedded with the ultrasonic sensor for measuring fluid flow; Described ultrasonic sensor comprises paired transmission sensor and receiving sensor, circumferentially positioned opposite of edge on butterfly plate; Or described ultrasonic sensor comprises transmission sensor, receiving sensor and reflector plate in groups, on butterfly plate, along circumferential arrangement, the ultrasonic wave that described transmission sensor sends reflexes to receiving sensor through reflector plate.
Preferably, the upper end of described valve rod is provided with the drive motors or the handle that rotate for actuate valve stem.
Preferably, described supersonic wave metering butterfly valve also comprises control section and power unit; Described control section comprises single-chip microcomputer and drive motors control module; In described single-chip microcomputer, store the normal flow data of typing, single-chip microcomputer is processed the data that send sensor and receiving sensor collection, and result and normal flow data are compared, and comparison result is fed back to drive motors control module; Drive motors control module is according to the comparison result control drive motors work of feedback. By coordinating of control section and drive motors, make supersonic wave metering butterfly valve, the fluid flow of reality not only can measure time, can also change out according to real-time traffic the size of valve, thereby automatically regulate and flow out flow, be applicable to unified management and Long-distance Control to pipeline.
Preferably, one end of described spool and valve rod lower end are fixed, and the other end is fixed with fixed axis in the position back to valve rod; Described fixed axis is connected with valve body by bearing. By the transitional function of bearing, make Spool rotating easier, open and close valve is more laborsaving.
The beneficial effects of the utility model are: the received sensor of the transmission sensor emission ultrasonic wave of ultrasonic sensor receives, ultrasonic sensor valve core rotation to open position time, the flow of fluid in measurement pipeline. Adopt ultrasonic sensor to measure fluid flow, certainty of measurement is not affected by liquid, there is no other obstacles in fluid through-hole, certainty of measurement is high, and simple in structure, easy for installation, long service life, has solved the problem that in pipeline, valve and flowmeter are installed separately, and has reduced cost; Can also change out according to real-time traffic the size of valve, thereby automatically regulate and flow out flow, be applicable to unified management and Long-distance Control to pipeline.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, 2, supersonic wave metering butterfly valve comprises valve body 1, is located at the butterfly plate 2 in valve body 1, the valve rod 3 that drives butterfly plate 2 to rotate; On butterfly plate 2, be embedded with the ultrasonic sensor for measuring fluid flow; Ultrasonic sensor comprises paired transmission sensor 4 and receiving sensor 5, circumferentially positioned opposite of edge on butterfly plate 2; The upper end of valve rod 3 is provided with the drive motors (not shown) or the handle 7 that rotate for actuate valve stem 3.
