Description
Technical field
The utility model relates to vertical flow measurement and control instrument fields, and in particular to a kind of for vertical flow measurement and control instrument
Control dish structure.
Background technique
The working principle of flow measuring and controlling instrument substantially fluid, by simultaneously impeller rotation, is encapsulated in leaf with certain speed
Permanent magnet in wheel also rotates with it, and is converted into electric signal by magnetoelectric transducer, send electric signal eventually by conducting wire
To converter intelligent processing, realize fluid instantaneous flow, integrated flux display and data on flows and microsystem between
Communication and control.Currently, the flow measuring and controlling instrument used is mainly split type flow measuring and controlling instrument, the disadvantage is that by flow accumulation with
Control unit and Electric Actuator and valve body are disposed on pipeline, on the one hand substantially increase production cost, another
Aspect occupies very big installation space again, while being not easy to carry, and therefore, vertical flow measurement and control instrument just comes into being, this
The advantages that kind flow measuring and controlling instrument has production cost low, saves installation space, while facilitating carrying, vertical flow measurement and control instrument packet
Control panel is included, control panel is for controlling uninterrupted, but existing control panel is due to using straight-through structure, this knot
There are many shortcomings for structure, for example, coefficient of friction is high, is easily damaged control panel etc. under the impact of high-pressure fluid for a long time and lacks
Point.
Utility model content
The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art,
There is provided that fluid circulation is more unobstructed, greatly promotes a kind of for vertical flow measurement and control instrument of control plane service life
Control dish structure.
To achieve the above object, the utility model provides following technical solution: one kind is for vertical flow measurement and control instrument
Control dish structure, it is characterised in that: include the rotating disc in the figure of eight, the rotating disc is equipped with opposite set up and one
The metering orifice of end opening, described rotating disc one end are provided with control panel, and the control panel is provided in metering orifice opposite position
When the connection of rotary motion disk Shi Keyu metering orifice and connection area is gradually increased or isolated flow control structure.
By adopting the above technical scheme, control panel is fixed setting, and metering orifice open at one end is arranged on rotating disc, works as rotation
Metering orifice when rotating disc on rotating disc can partially overlap with flow control structure or not be overlapped, the flow control when not being overlapped
It is in close state, can be gradually gradually increased to the direction rotation flow being completely coincident when partially overlapping or opposite direction rotates
Gradually become smaller overlapping area, flow is maximum rating when being completely coincident, otherwise flow is minimum state.
A kind of above-mentioned control dish structure for vertical flow measurement and control instrument can be further arranged to: the flow control
Structure includes the boss that control panel is arranged towards metering orifice open at one end, and fluted, the boss is arranged in the middle part of the boss
Groove two sides are provided with opposite the first drops flow control hole and the second drops flow control hole set up.
A kind of control dish structure of above-mentioned vertical flow measurement and control instrument can be further arranged to: the first drops stream
Amount control hole area becomes larger along clockwise direction, and the second drops flow control hole area is along clockwise direction gradually
Become smaller.
By adopting the above technical scheme, the first, second flow control hole of drops due to each section area it is not consistent, and
It is the first drops flow control hole along in the state being gradually increased, the second drops flow control hole is along clockwise clockwise
In gradually smaller state, although therefore the flow hole area open at one end that is opened up on rotating disc when turn disc be
It is fixed, but since the area of first flow control hole is to rotate clockwise the drops, second that direction becomes larger along rotating disc
The area of flow control hole is that the gradually smaller drops in direction is rotated clockwise along rotating disc, in turn rotating disc clockwise
Metering orifice becomes larger with the first, second flow control hole connected component, and flow also becomes larger therewith, when turn rotating disc counterclockwise
Flow is then in gradually smaller state, until making metering orifice and the first, second flow control hole complete clockwise or counterclockwise
When not being overlapped entirely, flow zero.
The utility model has the following beneficial effects: the flow control hole of special shape setting keeps fluid circulation more unobstructed and big
The cushion effect under high-pressure situations is reduced greatly, so that more coordinating between each component of vertical flow measurement and control instrument, promotes control
The service life of disk control plane.
The utility model is described in further detail with reference to the accompanying drawings and examples.
