Problems solved by technology

After docking, in a vibration and shock environment, the locking pin may be scratched from the locking groove, and the locking method is unreliable
[0005] In addition, none of the existing domestic quick-release self-sealing valves has been specially designed for zero leakage during the docking and separation process

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings of the description, please refer to Figure 1 to Figure 3 .

[0014] The fixed end half body mainly includes 1 - the fixed end nozzle; 2 - the fixed end valve; 3 - the fixed end valve seat; 301 - the ratchet; 4 - the sealing ring. The half body of the quick-release end mainly includes 5-outer sleeve; 501-ratchet; 6-lock spring; 7-pin; 8-screw sleeve; End valve seat; 11-quick release end nozzle; 12-sealing ring; 13-sealing ring.

[0015] The valve seat 3 at the fixed end and the screw sleeve 8 at the quick release end are screwed together with a single-thread coarse thread, which is convenient and labor-saving for docking, without special tools.

[0016] When the two halves are docked, the valve seat 3 at the fixed end is on top with the valve seat 9 at the quick release end, and the valve 2 at the fixed end is on top with the valve seat 10 at the quick release...

Abstract

The invention discloses a quick-release self-sealing valve, which belongs to the design field of hydraulic accessories of aircraft hydraulic systems, and comprises two halves of a fixed end and a quick-release end. When the two halves are docked, the oil passages are connected; when the two halves are separated, the respective oil passages are closed. The product has a compact structure, zero leakage during the docking and separation process, small butt separation force, convenient operation, no special tools, and reliable self-locking performance. The scheme of the invention is reasonable and reliable, has low dependence on components, has no precision components, and has low design and manufacturing costs; the invention is easy to operate, does not require professional training, and has no special skill requirements.

Description

technical field [0001] The invention belongs to the field of aircraft hydraulic system design and relates to a quick-release self-sealing valve. Background technique [0002] Quick-release self-sealing valves are commonly used accessories in aircraft hydraulic systems. It is mainly used in places where frequent disassembly is required in the hydraulic system. It can prevent hydraulic oil from leaking when it is separated, and it can connect the oil circuit when it is docked. However, it is required that there should be no accidental separation, so as not to block the hydraulic oil circuit and cause system failure. The existing domestic quick-release self-sealing valves mainly have the following structures: [0003] Multi-thread type: the two halves are connected by multi-thread screwing, and the thread rise angle is used to realize self-locking. This type of self-locking reliability is low, and for large-diameter products, the screwing and docking force is large, and speci...
