The air cylinder and the transmission mechanism are installed inside the shell body. The air cylinder comprises a left cylinder cover, a right cylinder cover, a cylinder barrel, a piston, a piston rod and a spring. The piston and the piston rod are fixedly connected, the piston rod and the shell body are fixedly connected, the piston and the cylinder barrel are sealed through a sealing element, a connecting piece is arranged on the outer side of the left cylinder cover in the axis direction of the piston rod, and an air inlet and outlet hole is formed in the left cylinder cover. The cylinder-driven pneumatic device has the advantages that the piston and the piston rod are fixed, an external load is connected with a cylinder body, pressure drives the cylinder body through air, the cylinder body transmits motive power to the external load, and therefore the external load is driven and motion stability is improved.
Description
Affiliated technical field
The utility model relates to a kind of start-stop device of valve, particularly a kind of Pneumatic actuator that is driven by cylinder body.
Background technique
When valve used at pipeline, its keying state or opening degree be by manually and automatic two kinds of control modes, and that automatic control mode has is pneumatic, electronic, surge and control mode such as gas-liquid linked, and pneumatic control is the safest the most frequently used a kind of control mode wherein.Traditional Pneumatic actuator is cylinder body and maintains static, and external load is connected with piston rod, promotes piston and piston rod with pressure gas, and piston rod is given external load transmission of power, realizes the driving of external load.This driving mode is had relatively high expectations to the rigidity of piston rod, and stationarity is relatively poor.
Summary of the invention
For overcoming the above-mentioned defective of existing Pneumatic actuator, the Pneumatic actuator that the utility model provides a kind of cylinder body to drive promotes cylinder body by pressure gas, and movement of cylinder block is given external load transmission of power, realizes the driving of external load, has improved the stationarity of motion.
The technological scheme that its technical problem that solves the utility model adopts is the Pneumatic actuator that a kind of cylinder body drives, comprise housing, cylinder and driving mechanism, cylinder and driving mechanism are installed in enclosure interior, described cylinder comprises left and right cylinder cap, cylinder barrel, piston, piston rod and spring, piston is fixedlyed connected with piston rod, piston rod is fixedlyed connected with housing, seal by seal element between piston and the cylinder barrel, the cylinder cap outside, a left side is provided with link along piston rod axis direction, and left cylinder cap is provided with air inlet/outlet.
Link is an axis of guide, and the axis of guide radially has through hole, axially runs through a ladder roller bearing in the through hole.
Driving mechanism comprises the shift fork of fixedlying connected with output shaft, shift fork is installed along piston rod axis direction symmetry, the other end of shift fork has the U-shaped guiding groove, described ladder roller bearing is through the U-shaped guiding groove, ladder roller bearing two ends cooperate installs bearing, described housing is provided with guide rail, and bearing is embedded in the guide rail.
The beneficial effects of the utility model are the Pneumatic actuator that adopt cylinder body to drive, and piston and piston rod maintain static, and external load is connected with cylinder body, and pressure gas promotes cylinder body, and cylinder body is given external load transmission of power, realize the driving of external load, have improved the stationarity of motion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment's plan view;
Fig. 2 is embodiment's plan view.
Among Fig. 1,2: 1. housing; 2. guide rail; 3. shift fork; 4. output shaft; 5. ladder roller bearing; 6. the axis of guide; 7. left cylinder cap; 8. piston; 9. seal element; 10. piston rod; 11. cylinder barrel; 12. spring; 13. right cylinder cap; 14. air inlet/outlet; 15. bearing.
Embodiment
As Fig. 1, shown in 2, the Pneumatic actuator that a kind of cylinder body drives, comprise housing 1, cylinder and driving mechanism, cylinder and driving mechanism are installed in housing 1 inside, described cylinder comprises left cylinder cap 7, right cylinder cap 13, cylinder barrel 11, piston 8, piston rod 10 and spring 12, piston 8 is fixedlyed connected with piston rod 10, piston rod 10 the other ends are fixedlyed connected with housing 1, seal by seal element 9 between piston 8 and the cylinder barrel 11, cylinder cap 7 outsides, a left side are provided with link along piston rod 10 axial directions, and the link in the present embodiment is an axis of guide 6, and the axis of guide 6 radially has through hole, axially run through a ladder roller bearing 5 in the through hole, left cylinder cap is provided with air inlet/outlet 14.
The driving mechanism that links to each other with cylinder comprises the shift fork 3 of fixedlying connected with output shaft 4, shift fork 3 is installed along piston rod 10 axial directions symmetry, the other end of shift fork 3 has the U-shaped guiding groove, described ladder roller bearing 5 is through the U-shaped guiding groove, ladder roller bearing 5 two ends cooperate installs bearing 15, housing 1 is provided with guide rail 2, and bearing 15 is embedded in the guide rail 2.
During work, by air inlet/outlet 14 incoming pressure gas, because piston 8 and piston rod 10 all maintain static, so pressure gas promotes cylinder body to left movement, both in the U-shaped guiding groove of the through hole of the axis of guide 6 and shift fork 3, rolled thereby drive ladder roller bearing 5, and along guide rail 2 moving linearly left, drove shift fork 3 in the time of 5 motions of ladder roller bearing and turn left again, thereby drive the rotation of output shaft 4, rotation angle can reach 90 °.
When cylinder body during to left movement, spring 12 is compressed, when stopping incoming pressure gas, spring 12 namely can rebound to original state, drives cylinder body in the bounce-back process and moves right, and is opposite when being moved to the left with cylinder body, shift fork 3 also can drive output shaft 4 and turn right, and can realize the keying of valve and so forth.
