For realizing above-mentioned purpose, the utility model provides a kind of novel pneumatic three-way valve.
A kind of Pneumatic three-way valve comprises valve body and piston, and said valve body is a cross right angle hollow pipeline, and its substantially horizontal one end is a water intake, and the other end is a water outlet, and airtight cylinder is installed in the Vertical direction upper end, and the lower end is another water outlet; Piston is installed in the described cylinder, cylinder below fixed air cylinder cap, cylinder wall is provided with gas channel and feeds cylinder interior; Be equipped with in the described valve body and can alternately stop up the valve disc of closing water outlet; Described piston is connected with valve disc through valve rod, is provided with Returnning spring between piston and the cylinder.
Said cylinder bottom embeds annular retaining ring is installed, and the cylinder head fixed card is on back-up ring top, and described gas channel is between piston and cylinder head.
The water outlet lower end of described cylinder lower end is equipped with the internal thread connection pipe fitting.
Described cylinder head also is provided with viewing window.
Described cylinder is connected through threaded connector with valve body.
The upper and lower mounted on surface of described valve disc has Sealing.
Described cylinder and valve body joint are provided with shaft seal.
Be provided with spring between the shaft seal of described cylinder head and valve body joint.
Compared with prior art, the utlity model has following advantage:
The utility model provides a kind of Pneumatic three-way valve, and airtight cylinder is installed in valve body Vertical direction upper end; Piston is installed in the cylinder, and cylinder wall is provided with gas channel and feeds cylinder interior, and pressurized air injects cylinder, drives valve disc through the promotion piston and opens and closes the entery and delivery port in the valve body; Piston is connected with valve disc through valve rod, is provided with Returnning spring between piston and the cylinder.Reciprocating type final controlling element, long service life, the unlatching life-span can reach 1,000,000 times, and is easy to maintenance.In automated machine equipment, compact structure, installing space is little, can reduce channel bend, can control fluid automatically again.
