Problems solved by technology
[0002] At present, most of the two-position three-way air pressure valves are controlled by manual or solenoid valves, and some of them also have pressure sensors. However, due to the limitation of the use position, the circuit control device cannot be used during work, and only the low air pressure control valve with automatic pressure limiting and deflation is required. , the air pressure is converted between 0mmHg and 100mmHg two-position three-way, lacking a two-position three-way valve that can be used without a second energy source

The invention discloses a micro-pneumatic pressure-sensing double-pin reversing valve. The pressure of a two-position three-way valve can be automatically limited, a pressure guiding swing frame (11) is locked by a plug pin A (7), a valve of an upper air bag (101) is opened to be inflated and expanded, an upper valve spring pressing piece (8) and an upper pressing piece spring (5) are pushed to be pressed on the pressure guiding swing frame (11), the pressure guiding swing frame (11) is fixed by a lock and does not rotate, the upper air bag (1) continues to be inflated and expanded to push the upper valve spring pressing piece (8) to rotate, the upper valve spring pressing piece plug pin guide column (801) drives the plug pin A (7) inserted into a plug pin A guide column hole (701) to retreat to be separated from the pressure guiding swing frame (11) for unlocking, an upper pressure guiding swing frame pressing strip (1103) and a pressure guiding swing frame pressing strip (1105) of the pressure guiding swing frame (11) rotate to press and release four valve elements (19) at the same time, the upper air bag (101) is deflated, a lower air bag (102) is inflated, the pressure guiding swing frame (11) rotates a plug pin B (9) to pop out a reverse lock, the actions of the upper side and the lower side are interchanged, and the opening and closing of four valves are interchangeable to realize two-position three-way, and the micro-pneumatic pressure-sensing double-pin reversing valve is a two-position three-way valve without a second energy source.
Description
technical field [0001] The invention relates to a micropneumatic valve, in particular to a micropneumatic pressure-sensing double-pin reversing valve. Background technique [0002] At present, most of the two-position three-way air pressure valves are controlled by manual or solenoid valves, and some of them also have pressure sensors. However, due to the limitation of the use position, the circuit control device cannot be used during work, and only the low air pressure control valve with automatic pressure limiting and deflation is required. , the air pressure is converted between 0mmHg and 100mmHg two-way three-way, and there is a lack of a two-way three-way valve that can be used without a second energy source. Contents of the invention [0003] The technical problem solved by the present invention is to provide a valve body (12) with a compact structure that avoids splicing and concentrating air leaks, double-pin dislocation opening and closing without delay errors, an...
