Detailed Description
The first embodiment,
As shown in fig. 1 and 2, the line control valve according to the present invention includes: the driving unit is connected with the stroke amplifying unit; the stroke amplification unit is connected with a valve plate 2, and the valve plate 2 is used for opening and closing a negative pressure pipeline 7. The driving unit can be an electromagnetic driving device and comprises an electromagnet 6 and an iron core 5 matched with the electromagnet 6; when the electromagnet 6 is energized, the iron core 5 and the electromagnet 6 are displaced relative to each other. The driving unit of the utility model can also be an electric push rod. The electric push rod is a novel linear actuating mechanism which mainly comprises a motor, a push rod, a control device and the like, and can realize remote control and centralized control. The electric push rod moves back and forth within a certain range of stroke. The electric push rod takes a direct current permanent magnet motor as a power source, and converts the rotary motion of the motor into linear reciprocating motion. The electric push rod has the working principle that the motor drives the pair of screw rod nuts after being decelerated by the gear. The rotary motion of the motor is changed into linear motion, and the push rod action is completed by utilizing the positive and negative rotation of the motor. The electric push rod is used to control the position of the valve plate 2 and thus the opening and closing of the pipeline 7.
The stroke amplifying unit can be a pulley block stroke amplifying device and comprises a pulley block consisting of a plurality of pulleys 4, and a belt 3 is wound on each pulley 4; one end of the belt 3 is fixed, and the other end of the belt is connected with the valve plate 2; the pulleys 4 comprise fixed pulleys 4 and movable pulleys 4 connected with iron cores 5; the fixed pulleys and the movable pulleys are sequentially and alternately arranged; the belt sequentially and alternately rounds the fixed pulley and the movable pulley.
The stroke amplification unit can also be a lever type and comprises a lever, wherein one end of the lever is connected with the driving unit, and the other end of the lever is connected with the valve plate 2; the lever is moved about an axis of rotation which is less than the distance from the drive unit than the valve plate 2. The displacement generated by the driving unit is amplified in a lever manner.
The valve plate 2 can be a drawer type inserting plate, and the valve plate 2 is inserted in a groove fixed on the pipeline 7; and is slidable within the slot. The valve plate 2 can also be in another form, and comprises a circular valve plate 2 body and a shaft positioned in the middle of the valve plate 2 body; the valve plate 2 body is overturned around the shaft. The valve plate 2 is driven to rotate by the rotation of the shaft, and the opening and closing of the pipeline 7 are controlled.
Still include valve plate 2 reset unit, valve plate 2 reset unit one end is connected valve plate 2, and the other end is fixed. The valve plate 2 reset unit can be a reset spring 1. The pipeline 7 can be a negative pressure pipeline 7. The control valve of the pipeline 7 has the advantages of simple and compact structure, low power consumption and quick switching action. The negative pressure pipeline 7 can be opened and closed simply and quickly, and energy consumption is saved for the vacuum dust removal device.
As shown in fig. 1, the line control valve is driven by an electromagnet 6, for example, an iron core 5 has an operating stroke of 10 mm, and the stroke is enlarged by 4 times through a belt 3 and pulley 4 set mechanism, so that the opening and closing stroke of the valve plate 2 reaches a pipe diameter of 40 mm. When the electromagnet 6 is not energized, the valve plate 2 pushes the valve plate 2 upward under the action of the spring force, opening the pipeline 7, as shown in fig. 1. When the electromagnet 6 is electrified, the iron core 5 drives the movable pulley block to move upwards, and the belt 3 pulls the valve plate 2 to move downwards to close the pipeline 7, as shown in fig. 2.
The pipeline control valve can be suitable for various pipelines, and is preferably suitable for a negative pressure pipe wheel of a vacuum dust removal device.
