Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0040] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0041] Such as Figure 1-5 Shown is the outline drawing of the double redundancy and high reliability linkage cylinder of the present invention, from which it can be seen that the double redundancy and high reliability linkage cylinder includes a cylinder main body 1, an intake selection valve 2, an exhaust valve 3 and a linkage valve 4. Wherein the intake valve 2 is connected with the intake port A of the cylinder main body 1 through threaded connection, the axial direction of the intake valve 2 and the cylinder main body 1 can be adjusted, and can be locked by the lock nut 5 after the adjustment is completed. The exhaust valve 3 is installed at the air inlet A to discharge the gas in the rodless cavity C when the piston...

Abstract

A high reliability linkage cylinder comprises a cylinder body (1), an intake valve (2), an exhaust valve (3) and a linkage valve (4). The intake valve (2) is connected with an air inlet A of the cylinder body (1), and the exhaust valve (3) is installed at the position of the air inlet A for discharging air in a rodless cavity C when a piston rod (1-2) in the cylinder body (1) is reset. The linkagevalve (4) is mounted at the stroke end of the piston rod. When the linkage valve does not work, a valve element assembly (4-4) is pressed against a linkage valve casing (4-1) and isolates an air inlet G and an air outlet H under the action of the spring force and the air pressure of the air inlet. When the piston rod (1-2) moves to the stroke end, the piston rod ejects an ejection pin (4-6) and apush rod (4-5) under the action of the piston rod (1-2). Under the action of the push rod (4-5), the valve element assembly (4-4) is ejected to communicate the air inlet G and the air outlet H to supply air to a downstream air using unit.

Description

technical field [0001] The invention relates to a highly reliable cylinder with linkage function. It can be applied to UAVs or other space vehicles and the linkage of pneumatic systems for industrial purposes. Background technique [0002] With the rapid development of aerospace, weapons, ships and industries, higher requirements are put forward for the reliability, integration and error prevention of pneumatic systems. For some systems, it is necessary for the execution cylinder to pneumatically actuate the next action after the execution of the action, and a margin requirement is put forward for the execution cylinder. In order to improve the reliability of the air circuit logic of the pneumatic system and reduce the load on the power supply, when the cylinder is executed to complete the action, no additional solenoid valve is needed but the air circuit logic is opened through mechanical triggering. At present, there are few researches on this kind of highly reliable cyl...
