Further, the air leakage channel is of an L-shaped structure.

Further, the air release block is of a cuboid structure.

Further, the limiting rod is rotated anticlockwise, the air leakage block moves upwards in the axial direction along the threads of the limiting rod, and when the air leakage block is completely matched with the sliding sealing groove, the air leakage channel is in a closed state.

The utility model has the advantages that: the structure of preventing the mistake at the trachea link of pneumatic valve is equipped with, after the switch-on atmospheric pressure, still need through the closed disappointing passageway, just can carry out the start and close work of pneumatic valve, the effectual mistake that prevents the outsider from opening.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

FIG. 1 is a schematic structural view of an anti-false-opening pneumatic valve of the present invention;

fig. 2 is a schematic cross-sectional view of the anti-misopening air pressure input ring.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 and 2, the present invention provides a pneumatic valve with anti-false-opening function, which comprises: the structure of the valve comprises a valve body 1, wherein a connecting block 2 is arranged at the upper end of the valve body 1, an anti-misopening air pressure input ring 3 is arranged at the upper end of the connecting block 2, an air pressure driving end 4 is arranged at the upper end of the anti-misopening air pressure input ring 3, an air pipe interface 5 is arranged on one side of the anti-misopening air pressure input ring 3, an air pressure channel 6 communicated with the air pipe interface 5 is arranged on the inner wall of the anti-misopening air pressure input ring 3, a valve clack 7 is hinged to the inner end of the air pressure channel 6, a limiting rod 8 is rotatably arranged at the edge of the bottom of the anti-misopening air pressure input ring 3, the end part of the limiting rod 8 is matched with the air pressure channel 6, a sliding seal groove 9 is arranged inside the top part of the air pressure channel 6, an air release block 10 is in threaded connection with the end part of the limiting rod 8, the upper part of the air release block 10 is movably embedded into the sliding seal groove 9, an air release channel 11 is arranged at the left part of the air release block 10, one end of the air release channel 11 is communicated with the air pressure channel 6, the other end communicates with each other with sliding seal groove 9, sliding seal groove 9 upper end is equipped with and pierces through to preventing the venthole 12 of the 3 up end of mistake opening atmospheric pressure input ring, disappointing passageway 11 is L type structure, it is the cuboid structure to let out gas piece 10, anticlockwise rotation restriction lever 8, and the piece 10 that loses heart carries out axial displacement up along with the screw thread of restriction lever 8, when letting out gas piece 10 and joining in marriage sliding seal groove 9 completely, loses heart passageway 11 and is in the encapsulated situation.
