Detailed description of the invention
The embodiment of the present invention will be described in further detail below.
The Novel self sealing push-pull valve of the present invention, its preferably detailed description of the invention is:
Including valve body, described valve body includes two support posts, is from top to bottom sequentially provided with hands 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 with outside
The annular seal space of isolation, filling airtight and watertight padding in annular seal space, described handwheel crossbeam is provided with valve rod, and the top of described valve rod is provided with hands
Wheel, the lower end of described valve rod is provided with valve plate, and the inner side of described two support posts part above described top cross-bar is provided with
Valve plate lead, the inner side of described two support posts part below described top cross-bar is provided with interior seal preload machine
Structure.
Described interior seal preload mechanism includes being located at and is positioned at described valve plate driving cog below inside two support posts
Bar, described driving rack is engaged with multiple sector gear 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 gear is 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.
