Specific embodiment
This utility model embodiment will be described in further detail below.
Novel self sealing push-pull valve of the present utility model, its preferably specific embodiment is:
Including valve body, described valve body includes two support posts, is from top to bottom sequentially provided with handss between two support posts
Wheel crossbeam, top cross-bar and base cross members, described top cross-bar is provided with pressing plate, and described pressing plate and top cross-bar are constituted and outside
The annular seal space of isolation, seals intracavity filling airtight and watertight padding, and described handwheel crossbeam is provided with valve rod, and the top of described valve rod is provided with handss
Wheel, the lower end of described valve rod is provided with valve plate, and the inner side of the described two support posts part above described top cross-bar is provided with
Valve plate lead, the inner side of the described two support posts part below described top cross-bar is provided with interior sealing pretightning force machine
Structure.
Described interior sealing pretension force mechanisms include being located at the driving cog after described valve plate inside two support posts
Bar, described driving rack is engaged with multiple sector gears from top to bottom, and the sector gear of foot is fixed with compression shell fragment axle, institute
State and be fixed with compression shell fragment on compression shell fragment axle, other sector gears are fixed with compression camshaft, described compression camshaft
On be fixed with compression cam.
The middle part of described compression shell fragment axle is provided with compression shell fragment axle and supports.
Described driving rack is provided with guide pad.
This utility model is directed to the present situation of existing plate valve seal poor performance and valve plate and sealing surface no pretightning force, carries out
Particular design, structure is simple, compact to design, and good sealing effect is it is adaptable to the cut-out of all kinds of material of gas, liquid, solid.
Specific embodiment:
Referring to Fig. 1, Fig. 2, including handwheel 1, handwheel crossbeam 2, valve rod 3, valve plate lead 4, support post 5, valve plate 6, pressure
