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-disassembly self-sealing valve and belongs to the field of hydraulic accessory design of aircraft hydraulic systems. The quick-disassembly self-sealing valve comprises a fixing end half body and a quick-disassembly end half body. When the two half bodies are in butt joint with each other, oil ways are connected; and when the two half bodies are separated, the corresponding oil ways of the half bodies are sealed. The quick-assembly self-sealing valve is compact in structure, zero leakage can be achieved in the butt joint process and the separation process, the butt joint force and separating force are small, operation is convenient, no special tool is needed, and the self-locking performance is reliable. The scheme of the quick-disassembly self-sealing valve is reasonable and reliable, the dependence on parts is low, no precise component is needed, and the design and manufacturing cost is low; and the quick-disassembly self-sealing valve is convenient to operate and free of professional training and the requirement for special skills.

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...
