Abstract
The utility model relates to an automatic pneumatic reversing cylinder which comprises a piston rod, a piston and a cylinder body. The cylinder body wall is provided with four air holes with respective one air hole at two sides. The four air holes are respectively connected with two bi-pneumatic twain five-through reversing values through an air tube. And the twain five-through reversing values are also connected through the air tube. The automatic pneumatic reversing cylinder of the utility model processes two eyelets as the gas control opening at the cylinder body of the ordinary double action cylinder, with two twain five-through reversing values, thereby the cylinder piston can make automatic and reciprocating movement with gas source. The utility model has novel and unique structure and is suitable for combustible and explosive occasions.
Description
Technical field
The utility model relates to cylinder, especially a kind of automatic gas control reversing cylinder.
Background technique
At present cylinder have adopt the solenoid valve commutation, the employing manual reverse of direction is arranged, the former has the automatic reverse function, but should not use at inflammable and explosive environment; The latter does not have the automatic reverse function.
Summary of the invention
The purpose of this utility model just provides a kind of novel structure, can adapt to the automatic gas control reversing cylinder that various environment use.
Automatic gas control reversing cylinder of the present utility model comprises piston rod, piston, cylinder body, have four pores on the cylinder wall, each pore of two ends wherein, four pores link to each other with two double air controlled switch valve with two-position and five-pass respectively by tracheae, and are also continuous by tracheae between switch valve with two-position and five-pass.
Automatic gas control reversing cylinder of the present utility model uses as the gas control mouth owing to process two apertures on the cylinder body of common double active cylinder, add two switch valve with two-position and five-pass, make as long as a ventilation source, cylinder piston will automatic reciprocating motion, its novel structure uniqueness is applicable to the occasion that contact is inflammable, explosive.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
The automatic gas control reversing cylinder comprises piston rod 3, piston 4, cylinder body 5, has four pore C, E, F, D on cylinder body 5 walls, and pore C meets the K of switch valve with two-position and five-pass 2 through tracheae, threeway 6 one tunnel
3Mouthful, another road meets the A of switch valve with two-position and five-pass 1
1Mouthful, pore D meets the K of selector valve 2 through tracheae, threeway 7 one tunnel
4Mouthful, another road meets the B of selector valve 1
1Mouthful, pore E, F meet the P of selector valve 2 respectively through tracheae
3, P
2Mouthful, the B of selector valve 2
2, A
2Mouth meets the K of selector valve 1 respectively through tracheae
2, K
1Mouthful, the Q of selector valve 2
3Mouth communicates the P of selector valve 1 with the external world
1Mouth is an air source inlet.
Automatic gas control reversing cylinder working principle of the present utility model:
Source of the gas is from the P of selector valve 1
1Mouth enters, through selector valve 1 outlet A
1Be divided into two-way, the one tunnel through selector valve 2 gas control mouth K
3, make selector valve 2 be in the diagram working position, another road enters left chamber through 5 mouthfuls of C of cylinder body, and promotion piston 4 and piston rod 3 move right and make system works.Right chamber gas is through valve D, B
1, O
1Mouth is discharged.Along with piston 4 continues to move right, piston 4 was closed pore E before this, then was pore E is communicated with cylinder body 5 left chambeies, then pore F was closed again, and at this moment working state of system is all constant.After piston 4 left side G moved past pore F, pore F communicated with cylinder body 5 left chambeies, and pressurized gas are through the P of pore F and selector valve 2
2, B
2Mouth arrival selector valve 1 gas control mouth K
2Make selector valve 1 commutation work, after selector valve 1 commutation, selector valve 2 left end gas control mouth K
3A through selector valve 1
1, O
2Mouth communicates with atmosphere.Source of the gas is from the P of selector valve 1
1Mouth enters, through selector valve 1 outlet B
1Be divided into two-way, the one tunnel through selector valve 2 right-hand member gas control mouth K
4, make selector valve 2 commutation work.Pore F and P like this
2Link to each other, be in closed condition, pore E is through P
3, A
2With gas control mouth K
1Communicate, another road enters right chamber through the pore D of cylinder body 5, promotes piston 4 and piston rod 3 and is moved to the left, and left chamber gas is through pore C, A
1, O
2Mouth leads to atmosphere.Equally, after piston 4 right side H moved past pore E, pore E communicated with cylinder body 5 right chambeies, and pressurized gas arrive selector valve 1 gas control mouth K through pore E
1Selector valve 1 is commutated again, and so the work of moving in circles down.
