Abstract
The utility model relates to the pneumatic rotary device of a pneumatic butterfly valve. The utility model is provided with an upper and a lower cylinder body, and the center of the pneumatic rotary device of a pneumatic butterfly valve is provided with an output shaft. V-shaped bulkheads on both sides of the pneumatic rotary device of a pneumatic butterfly valve, which are longitudinally and symmetrically arranged, divide the cylinder bodies into two cylinders which are mutually sealed, wherein, each cylinder is provided with a wobbling plate which is fixedly connected with the output shaft and is close matched with the inner wall of each cylinder body. The outside of the lower cylinder body is provided with pipe joints which are respectively communicated with the two cylinders. Because the wobbling cylinders are arranged, relative displacement does not occur in the course of transmission. The utility model which has the advantages of convenient heat preservation, no harm operation, and safety and has the advantages that personnel safety is protected, a valve fast starts and stops, and an extreme position is alone controlled by the pneumatic rotary device.
Description
The utility model relates to a kind of pneumatic rotary device of Pneumatic butterfly valve, belongs to valve type.
The swivel gear of Pneumatic butterfly valve adopts the plunger type cylinder usually, and piston column and link and valve shell produce relative displacement in the transmission process, insulation difficulty, the safety of harm operator and service worker; Plunger cylinder drives crank handle linkage mechanism, and unlatching or shut-in time are long, and the control of the valve limit is difficult, and limit switch is fragile.
The purpose of this utility model be to overcome above-mentioned technology defective, a kind of designs simplification be provided, open and close the pneumatic rotary device of rapid, safe and reliable Pneumatic butterfly valve.
The utility model is provided with lower cylinder body, and the centre is provided with output shaft, and And is divided into two cylinders of sealing mutually by shape next door, vertical symmetrically arranged both sides " V " with cylinder body.Be provided with in the cylinder with the fixed admittedly connection of output shaft and connect And and the close pendulum plate of joining of inboard wall of cylinder block, lower cylinder body is provided with the pipe joint that is communicated with two cylinders respectively outward.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1: the structural drawing of present embodiment;
Present embodiment is provided with lower cylinder body 1,2, the centre is provided with output shaft 3 And and by shape next door 4,5, vertical symmetrically arranged both sides " V " cylinder body is divided into two cylinders 6,7 of sealing mutually, be provided with in the cylinder 6,7 with output shaft 3 Gu and decide Lian Jie And and the close pendulum plate 8 of joining of inboard wall of cylinder block, the lower cylinder body 2 outer pipe joints 9,10 that are connected with cylinder 6,7 respectively that are provided with, the hunting range of pendulum plate 8 is 0-90 °, it depends on the setting in shape next door, both sides " V " 45, and the tip in " V " shape next door 4,5 and output shaft 3 sealings are lived and joined.
The outer surface of upper cylinder body 1 is provided with the direction board 11 ， And that are fixedly connected with output shaft 3 and is provided with hard-wired guard shield 12, and guard shield 12 is offered the scale that circular groove shows direction board 11.Present embodiment connects with butterfly valve by adpting flange, and its output shaft 3 is fixedly connected with the mandrel of butterfly valve.During operation, purification of compressed air promotes pendulum plate 8 and does interior arbitrarily angled the swinging back and forth of 0-90 ° of scope by cylinder 6,7, and the mandrel on output shaft adpting flange and butterfly valve makes the part turning valve reach the purpose of keying and throttling again.
The utility model adopts the swing type cylinder, does not have relative displacement in the transmission process, is convenient to insulation, the safety that does not endanger operation, attendant; Valve opening and shut-in time shorten greatly, and the limit of butterfly valve need not set up limit switch by the moving control of Pneumatic actuator device, and be safe and reliable.
