Description
Technical field
The invention belongs to electrically operated valve field, more particularly to a kind of Jing Yin controllable electric pinch valve.
Background technology
Pinch valve (Pinch Valve), also known as pipe clip valve, air bag valve, hoop stop valve etc. at home, now at sewage
The multiple fields such as reason, power plant, mining, chemical industry, medical treatment have application.According to the difference of type of drive, pinch valve can be divided into hand
Dynamic pinch valve, pneumatic pinch valve, electronic pinch valve and hydraulic pipe clipping valve.
The existing electronic pinch valve used is mostly to use electromagnet this kind of pinch valve is due to that can make as power drive
Microstructure, it is widely used in medical field etc..But there is following defect for electromagnetism pinch valve：(1) electromagnetic actuation and relieving
When can produce the sound of " whip ", it is impossible to meet the quiet requirement that hospital ward uses；(2) electromagnet only exists adhesive and relieving
Two states, the flow velocity of the uncontrollable tube fluid of pinch valve；(3) electromagnet starting current is very big；(4) electromagnet stroke is short,
Cause clamp valve block stroke short.
Electronic pinch valve especially is used in medical field, the sound that electromagnet is sent easily makes patient produce irritated feelings
Thread, it is unfavorable for Rehabilitation.
The content of the invention
The purpose of the present invention is the defects of being directed to prior art, there is provided a kind of practical application need that can meet hospital ward
Want, Jing Yin controllable electronic pinch valve.
To achieve these goals, the present invention uses following technical scheme：A kind of Jing Yin controllable electric pinch valve, including：
Control assembly, conversion of motion component, stepper motor, connecting rod, clamp head assembly in valve casing and valve casing；
Wherein described clamp head assembly includes upper valve block and lower disc, is flexible pipe path between upper and lower valve block；The stepping
Motor powered motion conversion component under control assembly control, the convert rotational motion of stepper motor is straight by conversion of motion component
Line moves, and the conversion of motion component connects upper valve block by connecting rod, the lengthwise movement of upper valve block make lower disc clamp or
Loosen flexible pipe.
The control assembly includes single-chip microcomputer and drive circuit, and single-chip microcomputer controls the rotating speed and rotating cycle of stepper motor,
Drive circuit provides suitable voltage and current for stepper motor.
The conversion of motion component includes screw mandrel, nut and linking arm；Stepper motor connection wire rod, screw mandrel using midpoint as pair
Claiming point, on the contrary, screw mandrel both sides are respectively arranged with a nut, each nut is connected both sides screw thread with a linking arm one end respectively, two
The linking arm other end is connected with the tail end of connecting rod.
The screw mandrel is fixed in valve casing by screw rod bracket.
The upper valve block is fixed on the top of connecting rod, and lower disc bottom is fixed in valve casing by spring.
Stepper motor connection wire rod, under control assembly control, screw mandrel is driven to rotate together.Stepper motor turns clockwise
When, both sides nut is moved to screw mandrel midpoint simultaneously, that is, one end of the attaching nut of two linking arms is moved to screw mandrel midpoint,
Then the other end end of linking arm is moved away from the direction of screw mandrel, drives the upper valve block of clamp head assembly to be transported towards lower disc
It is dynamic, so as to clamp body, prevent fluid from passing through.
During stepper motor rotate counterclockwise, on the contrary, upper and lower valve block decontrols body, fluid can pass through situation.
Control assembly carrys out rate of flow of fluid in control pipe body by controlling the closure degree of valve block.
Meanwhile in the case of stepper motor torsion is less, very big thrust is produced in connecting rod, play a role power and show
Write the effect of amplification.
The present invention using the Jing Yin controllable pinch valve designed by above-mentioned technical proposal, solve electromagnetism pinch valve noise it is big,
Non-adjustable, the problems such as starting current is big and stroke is short, the specific requirement of hospital ward is met, present invention addresses electricity
Magnetic clutch pipe valve can not adjust the problem of clamp head closure degree, can play control rate of flow of fluid by controlling the distance of valve block
Effect.
Brief description of the drawings
Fig. 1 is the structural representation of the electronic pinch valve valve casing inner assembly of the present invention.
Embodiment
The present invention is described further with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of electronic pinch valve valve casing inner assembly, including：Control assembly 1, conversion of motion component 2, step
Stepper motor 3, connecting rod 4, clamp head assembly 5.
Wherein control assembly 1 includes single-chip microcomputer 6 (containing accessory circuit) and drive circuit 7, single-chip microcomputer control stepper motor
Rotating speed and rotating cycle, drive circuit provide suitable voltage and current for stepper motor.
Conversion of motion component 2 includes screw mandrel 8, nut (9 and 10) and linking arm (11 and 12)；Screw mandrel 8 is symmetrical using midpoint
Point, on the contrary, screw mandrel both sides are respectively arranged with a nut, each nut is connected both sides screw thread with a linking arm one end respectively, and two connect
The tail end that the arm other end is connect with connecting rod 2 is connected.
Clamp head assembly includes upper valve block 13 and lower disc 14, is flexible pipe path between upper and lower valve block.
Control assembly 1 connects stepper motor 3 by wire, and stepper motor 3 is connected with screw mandrel 8.Nut 9 and nut 10 with
Screw mandrel midpoint is symmetrically placed, and nut 9 is connected with the A ends of linking arm 11, and nut 10 is connected with the A ends of linking arm 12, connection
The B ends of arm 11 and linking arm 12 are connected with the tail end of connecting rod 4.Upper valve block 13 is fixed on the top of connecting rod 4.Screw mandrel 8 is logical
Cross screw rod bracket 15 and be fixed in valve casing
When the drive screw mandrel 8 of stepper motor 3 turns clockwise, nut 9 and nut 10 move to the midpoint of screw mandrel 8 simultaneously,
It is exactly the A ends of linking arm 11 and the A ends of linking arm 12 while is moved to the midpoint of screw mandrel 8, then linking arm 11 and linking arm 12
B ends are moved to the direction of vertical remote screw mandrel, pass through connecting rod 4 so that upper valve block 13 moves to lower disc 14, i.e. clamp head closes
