Abstract
The utility model discloses a double-acting pneumatic execution mechanism with a standby gas storage function. The execution mechanism comprises a cylinder body (1) and a piston (2) arranged in the cylinder body (1), wherein an inner cavity of the cylinder body (1) is divided into an upper cylinder (11) and a lower cylinder (12) through the piston (2); a pushrod (21) is arranged on the piston (2); the end part of the pushrod (21) extends out of the cylinder body (1); a standby gas storage pocket (3) is also arranged on the cylinder body (1); the upper cylinder (11) and the lower cylinder (12) are simultaneously communicated with a main gas source and the standby gas storage pocket (3) through a control valve respectively. According to the execution mechanism, a valve can be reset to an open position or a closed position through the standby gas storage pocket when the main gas source fails; the execution mechanism has the advantages of high reliability, simple structure, convenience in use, compact structure, small size, attractive appearance and flexibility in application.
Description
Technical field
The utility model relates to industrial valve pneumatic actuator field, is specifically related to a kind of double-action pneumatic actuator with standby gas storage function.
Background technique
The double-action pneumatic actuator of prior art is the action that realizes valve by the intake and exhaust of two cylinders.But in the time that source of the gas breaks down, cylinder is locked in current location, cannot realize valve open position or off-position reset.
Model utility content
The technical problems to be solved in the utility model be to provide a kind of can be in the time of gas source fault by standby gas storage bag realize valve open position or off-position resets, reliability is high, simple in structure, easy to use, compact structure, volume are little, the double-action pneumatic actuator with standby gas storage function of appearance looks elegant, applying flexible.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of double-action pneumatic actuator with standby gas storage function, comprise cylinder block and be located at the piston in cylinder block, the inner chamber of cylinder block is divided into upper cylinder and lower cylinder by described piston, described piston is provided with push rod, the end of described push rod is stretched out cylinder block and is arranged outward, on described cylinder block, be also provided with standby gas storage bag, described upper cylinder and lower cylinder are connected with gas source, standby gas storage bag by control valve respectively simultaneously.
Further improvement as technique scheme:
Described standby gas storage bag is made up of sidewall and end cap, and one end of described sidewall is connected with the end part seal of cylinder block, and the other end of described sidewall is connected with end bracket enclosed.
The utility model has following advantage with the double-action pneumatic actuator of standby gas storage function:
1, the utility model comprises cylinder block and is located at the piston in cylinder block, the inner chamber of cylinder block is divided into upper cylinder and lower cylinder by piston, piston is provided with push rod, the end of push rod is stretched out cylinder block and is arranged outward, thereby the utility model can be served as the drive unit of straight stroke valve, by source of the gas to cylinder both sides cylinder body air feed realize valve unlatching, close or regulate aperture; And because the utility model is provided with standby gas storage bag with the cylinder block of the double-action pneumatic actuator of standby gas storage function, upper cylinder and lower cylinder are connected with gas source, standby gas storage bag by control valve respectively simultaneously, in the time that gas source breaks down, standby gas storage bag can automatically switch to alternative gas source and realize standby gas storage function, thereby realize valve reciprocating action, or only give a side cylinder air feed, thereby realize as required valve open position or off-position reset, have advantages of that reliability is high, simple in structure, easy to use.
2, the utility model cylinder block is provided with standby gas storage bag, and standby gas storage bag and cylinder block adopt integral type design, and compact structure, volume are little, appearance looks elegant, and the configuration of on-the-spot gas circuit pipeline is more succinct, takies installing space still less.
3, upper cylinder of the present utility model and lower cylinder are connected with gas source, standby gas storage bag by control valve respectively simultaneously, can change to realize by simple gas circuit the displacement of failsafe valve position, applying flexible.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's sectional structure schematic diagram.
Marginal data: 1, cylinder block; 11, upper cylinder; 12, lower cylinder; 2, piston; 21, push rod; 3, standby gas storage bag; 31, sidewall; 32, end cap.
Embodiment
As shown in Figure 1, the present embodiment comprises cylinder block 1 and is located at the piston 2 in cylinder block 1 with the double-action pneumatic actuator of standby gas storage function, the inner chamber of cylinder block 1 is divided into upper cylinder 11 and lower cylinder 12 by piston 2, piston 2 is provided with push rod 21, the outer layout of cylinder block 1 is stretched out in the end of push rod 21, on cylinder block 1, be also provided with standby gas storage bag 3, upper cylinder 11 and lower cylinder 12 are connected with gas source, standby gas storage bag 3 by control valve respectively simultaneously.
In the present embodiment, standby gas storage bag 3 is made up of sidewall 31 and end cap 32, and one end of sidewall 31 is connected with the end part seal of cylinder block 1, and the other end of sidewall 31 and end cap 32 are tightly connected.
The working procedure of the present embodiment is as follows: when gas source is during to upper cylinder 11 air feed, piston 2 drives push rod 21 to move down, valve closing; When gas source is during to lower cylinder 12 air feed, piston 2 drives push rod 21 to move up, valve open.Simultaneously, at gas source during to upper cylinder 11 or lower cylinder 12 air feed, gas source is simultaneously also to standby gas storage bag 3 air feed, break down once gas source, standby gas storage bag 3 can replace the effect of gas source, use valve realize reciprocating action by setting, or or only give upper cylinder 11 or lower cylinder 12 air feed, realize as required valve open position or off-position reset.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technological schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
