A kind of air-flow sentinel valve, comprise valve seat and cylinder block, it is characterized in that: valve seat is divided into a left side, right valve seat, be installed in the left side of cylinder block respectively, right both sides, be provided with blocking device in the right valve seat, the box type piston tube is installed in the valve seat and connects the import and export of valve seat, become unique access way, the left end of piston cylinder is pressed by pressure spring, and the right-hand member of piston cylinder is just in time corresponding with blocking device, and can seal by blocking device, piston and piston cylinder in the cylinder block are connected and fixed the left side of cylinder block, right air cavity respectively with ventilating hole A, B is communicated with, an electromagnetic valve gas break-make, make piston drive the piston cylinder move left and right, rapidly opening/shutting valve.
For solving the problems of the technologies described above, the utility model adopts following further technological scheme:
The air cavity of described cylinder block is surrounded by piston cylinder periphery, cylinder block outer wall and left and right valve seat, and described left and right sides valve base inner wall forms and the close-fitting back-up ring of piston cylinder periphery.
Is connected with valve component by rib in the described right valve seat, leaves between right valve seat and valve component and export the passage that is communicated with, described blocking device is located on the valve component.
Described blocking device is a sealing gland.
Described left valve base inner wall is provided with shoulder, and the right-hand member of piston cylinder is provided with link, and the left end and the shoulder of pressure spring are fixed, and right-hand member and link are fixed.
Described piston is the O type, is enclosed within outside the piston cylinder, and piston cylinder is provided with left and right sides block, and piston is installed between the block of the left and right sides.
The utility model compared with prior art has the following advantages and effect: 1, the hollow design of piston cylinder has reduced the weight of whole valve body, makes valve body slim and graceful; 2, the bidirectional-movement cylinder helps spring to reply, and driving pressure is low, makes valve opening and closing rapid, the flow rate height, and prolonged working life greatly.
