Abstract
The utility model relates to a valve body flow control mechanism, in particular to a valve body flow control mechanism with flow intercepting areas of multiple work positions changed linearly. The valve body flow control mechanism comprises a plurality of valve body flow control work positions arranged in parallel, and each valve body flow control work position comprises a motor, a lead screw driven by the motor, a lead screw thread counter vertically arranged on one side of the lead screw, a tapered valve element arranged at the front end of the lead screw and driven by the lead screw and a valve seat arranged at the front end of the valve element. The valve elements are driven to move through the lead screws, the lead screw thread rotation amount is detected through the lead screw thread counters, the movement distance of the valve elements is obtained by multiplying the lead screw thread rotation amount and the known screw pitch of the lead screws, and therefore the control results and the control parameters of the flow intercepting areas are made to be changed linearly.
Description
Technical field
The utility model relates to a kind of valve body flow control mechanism, relates in particular to a kind of valve body flow control mechanism of multi-position captured area linear change.
Background technique
Thereby valve body flow control mechanism is by changing the control mechanism of the captured area change flow between spool and valve seat, existing valve body flow control mechanism adopts cylinder to promote valve core movement, by control cylinder piston rod movement apart from controlling captured area, yet cylinder piston rod move distance is difficult to pass through cylinder applied thrust and Accurate Estimation, makes to control result and become nonlinear sag vertical curve to change with applied thrust.
Model utility content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of valve body flow control mechanism that makes to control the multi-position captured area linear change of result linear change is provided.
The utility model is to be achieved by the following technical programs:
A kind of valve body flow control mechanism of multi-position captured area linear change, comprise a plurality of valve body flow control stations that be arranged in parallel, described each valve body flow control station comprises motor, by motor-driven leading screw, be vertical at the wire rod thread counter of leading screw one side, be located at the screw-driven taper valve core of leading screw front end and be located at the valve seat of spool front end.
The beneficial effects of the utility model are:
Owing to adopting leading screw to drive valve core movement, by wire rod thread counter, detect threads of lead screw rotating amount, the product of the pitch by threads of lead screw rotating amount and known screw mandrel draws the move distance of spool, makes the control result and the linear variation of control parameter of captured area.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure: 1. valve body flow control station, 2. motor, 3. leading screw, 4. wire rod thread counter, 5. spool, 6. valve seat.
Embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in the figure, the utility model comprises a plurality of valve body flow control stations 1 that be arranged in parallel, described each valve body flow control station comprises motor 2, by motor-driven leading screw 3, be vertical at the wire rod thread counter 4 of leading screw one side, be located at the screw-driven taper valve core 5 of leading screw front end and be located at the valve seat 6 of spool front end.
Owing to adopting leading screw to drive valve core movement, by wire rod thread counter, detect threads of lead screw rotating amount, the product of the pitch by threads of lead screw rotating amount and known screw mandrel draws the move distance of spool, makes the control result and the linear variation of control parameter of captured area.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
