Abstract
The utility model relates to a driver of a single-cylinder double-piston pneumatic ball valve. The utility model is characterized in that both inner sides of a cylinder is respectively provided with an air chamber, a piston and a driving arm; the two driving arms are respectively connected with two connecting rods on an eccentric wheel to form a driver of a single-cylinder double-piston ball valve; the utility model has the advantages of capability of shortening the length of the cylinder in a maximum limit, small size, light weight, reliable operation, good safety performance and improvement of output torque.
Description
The utility model relates to the instrument and meter for automation field, belongs to the double-piston driver in the pneumatic ball valve specifically, is widely used in making on the delivery line in fields such as oil, chemical industry, water power, light textile completely open and close and uses.
Present used driver, its transmission arm tooth bar, and eccentric wheel is established gear, and transmission arm and eccentric wheel are meshing with each other by the tooth mouth, because there is a dead angle in gear engagement, the moment of transmission is inhomogeneous, volume is big simultaneously, and is single cylinder list piston type, and output torque is little, complex structure, the poor stability of operation.
The purpose of this utility model provides that a kind of output torque is big, and volume is little, and driving torque is even, and the pneumatic ball valve of piston type that shortens cylinder length simultaneously to greatest extent drives moving device.
For finishing the technological scheme that above-mentioned purpose is taked: left air chamber and right air chamber are established in the both sides in the cylinder, left piston and right piston are set respectively simultaneously, Left Drive arm one end is fixed in left piston, the other end is connected with a connecting rod on the eccentric wheel, right transmission arm one end is fixed in right piston, and the other end is connected with another connecting rod on the eccentric wheel, and rotating shaft is set in the eccentric wheel, rotating shaft is connected with valve rod, and establish into or outlet passageway the both sides of cylinder and centre.
The utility model is owing to adopt same cylinder double-piston, double-piston is fixed L shape transmission arm respectively, when the effect of Air Force by compression of left and right piston, two-piston is to the inside when moving mutually, and is L shaped and fall L shaped two transmission arms and constitute plug-in type, make full use of the cylinder interior space, shorten the length of cylinder to greatest extent, simultaneously because driving mechanism is arranged on cylinder interior, it is little and in light weight to have a bodily form, few simple in structure and the reliable and safety of part, even more important increase output torque.
The utility model is embodiment described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural drawing.
According to shown in Figure 1, left air chamber 11 and right air chamber 6 are established in both sides in the cylinder 9, left piston 1 and right piston 5 are set respectively simultaneously, Left Drive arm 10 1 ends are fixed in left piston 1, and the other end of Left Drive arm 10 is connected with connecting rod 8 on the eccentric wheel 2, and an end of right transmission arm 4 is fixed in right piston 5, the other end of right transmission arm 4 is connected with the connecting rod 3 on the eccentric wheel 2, the C of the both sides A of cylinder 9 and B and centre is provided with rotating shaft 7 for advancing or outlet passageway in the middle of the above-mentioned eccentric wheel 2, and this rotating shaft 7 is connected with valve rod.
When pressurized air under controlled circumstances, air enters left and right air chamber 11 and 6 from A and B passage.Promote left and right piston 1 and 5 in succession, by left and right transmission arm 10 and 4 drivening rods 8 and 3, make eccentric wheel 2 rotate 90 ° in the counterclockwise direction, rotating shaft 7 drives connected ball valve valve rod under the drive of eccentric wheel 2, rotate 90 ° in the same way, ball valve is finished opened or closed.Pressurized air in the cylinder is discharged from C-channel.
