" and this series products is when mounted owing to require to guarantee that spool is in erectility, so its application area is limited; In addition, owing to require between piston and valve body, spool and the valve body that higher coaxality and fit tolerance are arranged, and valve body adopts monolithic construction again, so the body cavity of this series products manufacturing processing difficulties, up-to-standard rate are low.For this reason, people expect to invent a kind of 2/2-way Pneumatic valve product that installation direction is unrestricted, valve body adopts separate assembling to install for valve body, with the application of further expansion 2/2-way Pneumatic valve product, effectively enhance productivity, reduce manufacture cost.
The model utility content
The technical problems to be solved in the utility model is to overcome defective and the deficiency that the installation direction that has the existence of 2/2-way Pneumatic valve product now is limited, the integrated type body cavity is made processing difficulties, up-to-standard rate is low, provide the 2/2-way Pneumatic valve product that a kind of installation direction does not limit, valve body employing separate assembling is installed, manufacturing is easy to process to society, with the application of further expansion 2/2-way Pneumatic valve product.
The technological scheme that its technical problem that solves the utility model adopts is: separate assembling 2/2-way Pneumatic valve comprises cylinder and valve body, be provided with piston moving up and down in the described cylinder, the cylindrical outer wall of described piston is embedded seal ring, the center of described piston connects piston rod, and described piston-rod lower end is provided with spool; Described cylinder sidewall is provided with the gas control interface; Described valve body two ends are respectively equipped with inlet union and outlet connection, passage is separated by the valve plate that is fixed in described body cavity between described inlet union and the outlet connection, and the described body cavity at position is provided with the valve port of level between described valve plate and the described outlet connection; The lower end of described cylinder is provided with the lower cover with described cylinder inner wall sealing, and described lower cover center is established through hole and extended down in the described valve body for described piston rod; Described valve body top is fixedly connected with valve gap, and described cylinder is connected in described valve gap.
Described gas control interface is two gas control interfaces up and down, and described two gas control interfaces are communicated with respectively and are positioned at the described piston described cylinder air chamber of both sides up and down.
The central through bore of described lower cover is established two stepped ring forgings up and down, is embedded oil-impregnated bearing and seal ring respectively in described two stepped ring forgings.
The utility model separate assembling 2/2-way Pneumatic valve product is formed by stacking mutually by the cylinder on top and the valve body of bottom, and wherein said valve body top is fixedly connected with valve gap, and described cylinder is connected in described valve gap.After adopting split modular structure, for the cylinder part that interior cylinder size and degree of finish are had relatively high expectations, its manufacturing difficulty reduces greatly, and manufacturing efficiency improves, and cost descends, and is easy to maintenance.Described cylinder sidewall is provided with two gas control interfaces up and down, and connection is positioned at the described piston described cylinder air chamber of both sides up and down respectively, what make described body cavity passage closes and opens with the oil pressure of described inlet union and described spool mounting point all irrelevant, has enlarged the application of 2/2-way Pneumatic valve product greatly.The utility model product structure is simple, good reliability, cheap for manufacturing cost, can be widely used in the Pneumatic component field.
