Description
Technical field
The utility model relates to flow cavitation result technical field, is specifically related to a kind of volume control device based on stepper motor.
Background technology
Flow control valve is applied in pressure pipeline, when the pressure of valve import and export changes, flow-control threshold switch is the most smooth and easy, very important effect is had for pressure pipeline system, the effect of flow control valve opening and closing only at general big flow water inlet and there is no adjustable function, some high-end big flow control valves can pass through controller Electronic Control flow, but cannot be read by naked eyes, and high-end big flow control valve price general charged is expensive.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is proposed that realize that cost is low and a kind of based on stepper motor the volume control device that can be read by naked eyes.
nullThe utility model is addressed by following technical proposals: a kind of volume control device based on stepper motor，Including device body，It is characterized in that: described body lower part is water flowing portion，It is opening/closing portion in the middle of described body，Described opening/closing portion is internally provided with opening and closing passage，It is provided with opening and closing lock in described opening and closing passage，Described opening and closing lock top is disc，Bottom is lamellar body，Described lamellar body can move up and down thus realize the flow-control in water flowing portion，It is provided with cannelure outside described disc，O RunddichtringO it is provided with on described cannelure，It is provided with back-moving spring between described disc bottom and opening/closing portion bottom，Described round plate upper surface is provided with little bearing，Described opening/closing portion top is provided with stepper motor，It is fixed with cam on described stepper motor output shaft，Described cam forms disk cam mechanism with described little bearing，It is provided with arrow on described cam，Described opening/closing portion is additionally provided with the graduation apparatus corresponding with described arrow.
Further, described stepper motor is arranged on the motor mounting plate on described opening/closing portion top.
Further, described opening/closing portion bottom is provided with the cylinder table of spacing back-moving spring.
The utility model has the advantage of: utilize stepper motor and cam mechanism to achieve the control of flow, directly can also directly read open and-shut mode of the present utility model from the outside of body, and the utility model realizes low cost, it is very suitable for high volume applications at big flow water pipe.

Fig. 2 is whole interior schematic diagram of the present utility model.
Fig. 3 is partial schematic diagram of the present utility model.
Fig. 4 is opening and closing lock schematic diagram of the present utility model.
Detailed description of the invention
nullWith detailed description of the invention, the utility model is described in further detail below in conjunction with the accompanying drawings: such as Fig. 1、Fig. 2、Shown in Fig. 3 and Fig. 4，A kind of volume control device based on stepper motor，Including device body 1，It is characterized in that: described body 1 bottom is water flowing portion 1.1，It is opening/closing portion 1.2 in the middle of described body 1，Described opening/closing portion 1.2 is internally provided with opening and closing passage 1.21，It is provided with opening and closing lock 2 in described opening and closing passage 1.21，Described opening and closing lock 2 top is disc 2.1，Bottom is lamellar body 2.2，Described lamellar body 2.2 can move up and down thus realize the flow-control in water flowing portion 1.1，It is provided with cannelure 2.11 outside described disc 2.1，It is provided with O RunddichtringO 3 on described cannelure 2.11，It is provided with back-moving spring 4 between described disc 2.1 bottom and opening/closing portion 1.2 bottom，Described round plate 2.1 upper surface is provided with little bearing 5，Described opening/closing portion 1.2 top is provided with stepper motor 6，It is fixed with cam 7 on described stepper motor 6 output shaft，Described cam 7 forms disk cam mechanism with described little bearing 5，It is provided with arrow 7.1 on described cam 7，Described opening/closing portion 1.2 is additionally provided with the graduation apparatus 1.22 corresponding with described arrow 7.1.
Described stepper motor 6 is arranged on the motor mounting plate 1.23 on described opening/closing portion 1.2 top, and described opening/closing portion 1.2 bottom is provided with the cylinder table 1.24 of spacing back-moving spring 4.
The utility model in use, is so work:
1. when the utility model needs to carry out flow-control, having only to control stepper motor 6 makes stepper motor 6 crawl along clockwise direction move, so opening and closing lock 2 just moves downward thus blocks the current in opening and closing passage 1.21, because stepper motor 6 can realize crawl motion, during stepper motor 6 slowly moves, so it is achieved that the flow-control of current, and because the arrow alignment graduation apparatus 1.22 arranged on cam 7, so, human eye can also easily read the flow open and-shut mode of current.
Protection domain of the present utility model includes but not limited to embodiment of above; protection domain of the present utility model is as the criterion with claims, replacement that any those skilled in the art making this technology is readily apparent that, deforms, improves and each fall within protection domain of the present utility model.
