Description
Technical field
The utility model belongs to pneumatic valve technical field, particularly a kind of pneumatic quick-closing valve.
Background technique
The valve rod end of existing pneumatic valve is nut, by screw thread, valve rod is linked together, then fixes with bearing pin, finally by locking nut, spool is linked together, and complex structure is loaded down with trivial details, has the shortcoming of growing process time; The valve rod lower end head of existing pneumatic valve is plane structure, higher to the coaxality requirement on machining accuracy of valve rod, has the shortcoming of growing process time; The O type circle of existing pneumatic valve is arranged on the top of flap, relies on screw thread to tighten to seal, and in tightening, O type circle is vulnerable to wearing and tearing in various degree, has shortened the working life of O type circle; The gasket seal of existing pneumatic valve relies on screw thread to tighten sealing, and in tightening, gasket seal is also subject to wearing and tearing in various degree, has shortened the working life of gasket seal.
Summary of the invention
For prior art exist deficiency, the utility model provide a kind of simple in structure, practical, cost is low and have the pneumatic quick-closing valve compared with the long life.
The technical solution that the utility model adopts is: a kind of pneumatic quick-closing valve, comprise cylinder body, valve body, valve gap and spool, spool is arranged in valve body, and described spool comprises valve rod, divided ring, locking nut, connecting stud, screw, flap, gasket seal, O type circle and sealing gland; Between described sealing gland and flap, be provided with gasket seal and O type circle, described sealing gland compresses gasket seal and O type circle by screw; One end of connecting stud is fixedly connected with flap, and the other end of connecting stud is connected with locking nut; The bottom of described valve rod is provided with groove, and described divided ring is arranged in groove, and described valve rod is connected with connecting stud by locking nut.
Described valve rod bottom head is sphere.
Compared with prior art, the beneficial effect that the utility model has is: 1: by stem bottom, groove being set, divided ring is arranged in groove and by locking nut spool entirety is closely connected, and has simple in structure, practical, process time is short, the advantage that cost is low.
2: be set to sphere by valve rod lower end, make valve rod have fine adjustment function, transmission power is more reliable.
3: O type circle is arranged on to the bottom of flap, sealing gland compresses O type circle by screw, compress rather than tighten by screw thread owing to adopting, solve O type circle and be vulnerable to the defect of wearing and tearing, thereby extended the working life of workpiece.
4: by screw, sealing gland is compressed gasket seal, owing to adopting compression rather than screw thread to tighten, solve gasket seal and be vulnerable to the defect of wearing and tearing, make the more close gasket seal of point of action of clamping force, clamp better effects if, sealing has more reliably extended the working life of workpiece simultaneously.
