Abstract
The invention relates to a butterfly valve driving device based on a gear transmission mechanism. The butterfly valve driving device is composed of an air cylinder, a rack, a gear, a key, a valve rod and a valve clack. One end of the rack is connected with the air cylinder, and the air cylinder is a mini air cylinder and is used for performing relevant deflation or inflation operation. The other end of the rack is connected with the gear, and the rack moves to drive the gear to rotate. The other end of the gear is connected with the valve rod, the gear rotates to drive the valve rod to rotate, the key is arranged between the gear and the valve rod, and the circling motion of the gear is converted into the circling motion of the valve rod through the key. The valve clack is arranged at the lower end of the valve rod, a valve clack pressing plate and a sealing ring are arranged between the valve rod and the valve clack and are fixedly connected to the valve rod through a bolt and a pin, and the valve rod rotates to drive the valve clack to rotate. The air cylinder is inflated or deflated, so that the rack moves to drive the gear to rotate, then the gear drives the valve rod to rotate, and finally opening or closing of the valve clack in a valve body is achieved. The butterfly valve driving device has the beneficial effects of being low in price, small in pressure angle and high in transmission efficiency.
Description
Technical field
The present invention relates to butterfly valve drive unit, be specifically related to a kind of butterfly valve drive unit based on gear drive.
Background technique
Valve is the necessary component of petrochemical industry, Process Equipment, huge number, and function differs, and plays very important effect in actual industrial.Therefore, valve actuator design is necessary.
Consider that the original supporting pneumatic actuating device of butterfly valve is expensive, and pressure angle is bigger than normal during the transmission of linkage type pneumatic actuating device, the factors such as transmission efficiency is low, therefore for the industrial requirement of butterfly valve drive unit, based on gear drive, the present invention proposes a kind of butterfly valve drive unit based on gear drive and implementation thereof.
Summary of the invention
The object of the present invention is to provide a kind of butterfly valve drive unit based on gear drive, have that low price, pressure angle are little, transmission efficiency advantages of higher.
Based on a butterfly valve drive unit for gear drive, be made up of cylinder, tooth bar, gear, key, valve rod and flap.
Described tooth bar one end is connected with cylinder, and cylinder is mini cylinder, in order to carry out the venting of being correlated with or charge operation.The described tooth bar the other end is connected with gear, and tooth bar moving belt moving gear rotates.
The described gear the other end is connected with valve rod, and pinion rotation band ovable valve stem rotates, and be provided with key between described gear and valve rod, the circular movement of gear is changed into the circular movement of valve rod by key.
Described valve rod underpart is mounted with a flap, is provided with flap pressing plate and seal ring between valve rod and flap, be fixedly connected on valve rod by bolt and pin, valve rod rotates and drives flap to rotate.
Described by inflating cylinder or exitting, thus realize tooth bar and move, tooth bar moving belt moving gear rotates, and then gear driven valve rod rotates, and finally realizes the unlatching of flap inside valve body or closedown.
Advantage of the present invention: low price, pressure angle are little, transmission efficiency is high.

Fig. 3 is partial sectional view of the present invention.
Wherein: 1. flap, 2. valve rod, 3. gear, 4. key, 5. tooth bar, 6. cylinder, 7. valve body, youngster. flap pressing plate, 12. seal rings, 13. bolts, 14. pins.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of butterfly valve drive unit based on gear drive, is made up of flap 1, valve rod 2, gear 3, key 4, tooth bar 5 and cylinder 6 in the present invention.
Described tooth bar 5 one end is connected with cylinder 6, and cylinder 6 is mini cylinder, in order to carry out the venting of being correlated with or charge operation.Described tooth bar 5 the other end is connected with gear 3, and tooth bar 5 moving belt moving gear 3 rotates.
Described gear 3 the other end is connected with valve rod 2, and gear 3 rotating band ovable valve stem 2 rotates, and be provided with key 4 between described gear 3 and valve rod 2, the circular movement of gear 3 is changed into the circular movement of valve rod 2 by key 4.
Described valve rod 3 underpart is mounted with a flap 1, is provided with flap pressing plate and seal ring 12, is fixedly connected with by bolt 13 with pin 14 between valve rod 3 and flap 1, valve rod 3 rotates and drives flap 1 to rotate.
Described by inflate cylinder 6 or exit, thus realize tooth bar 5 and move, tooth bar 5 moving belt moving gear 3 rotates, and then gear 3 is with ovable valve stem 2 to rotate, and finally realizes the unlatching of flap 1 inside valve body 7 or closedown.
