Abstract
The utility model discloses a pneumatic valve device, which comprises a valve seat (15), wherein two ends of the valve seat (15) are connected by an externally-sheathed nut (13), an O-shaped seal ring (14) and a hose joint (12); a diaphragm piece (1) is fixed on the valve seat (15); the diaphragm piece (1) and a top plate (11) are connected by a bolt; the top plate (11) and a central spindle (8) are connected by a bolt; the central spindle (8) is connected with a piston (5); a big spring (6) and a small spring (7) are sheathed outside the piston (5); a valve body cover (9) is sheathed outside an O-shaped seal ring (10); the O-shaped seal ring (10) is sheathed outside the top plate (11); the upper part of a valve body (3) and the upper part of the piston (5) are connected; the lower part of the valve body (3) and the diaphragm piece (1) are connected; a seal ring (4) is connected with the lower part of the piston; and a plug (2) is connected with the valve body (3). The pneumatic valve device has the advantages that the diaphragm piece is driven by the piston motion principle to generate tension so as to achieve a purpose of automatically adding water. The pneumatic valve device is simple and effective, is stable to operate, brings considerable economic benefits, has the advantages of simple structure, good use continuity and low cost, and does not need to be operated by people, and the failure rate is greatly reduced.
Description
Technical field
The automatic adding set of model utility, particularly be the added automatically system device in the horizontal sideline of a kind of PCB.
Background technique
The PCB horizontal line; Some paragraph need carry out liquid medicine and add automatically, and general interpolation need be passed through ball valve, realizes adding function; So very inconvenient; Cause lot of manpower and material resources waste and don't convenient, or buying large-scale automatic interpolation equipment has increased cost so virtually again, has caused burden to the client.
The model utility content
The purpose of the utility model is that design is a kind of simple in structure, need not people's operation, uses continuity, the extraordinary a kind of pneumatic valve device of stationarity.
A kind of pneumatic valve device of the utility model comprises valve seat 15, and the two ends of valve seat 15 link to each other with hose coupling 12 through cap nut 13, O RunddichtringO 14; Diaphragm 1 is fixed on the valve seat 15, and diaphragm 1 is solid on valve seat 15, and diaphragm 1 links to each other with top board 11, top board 11 and mandrel 8 usefulness bolts; Mandrel 8 links to each other with piston 5; Be with big or small spring 6,7 outside the piston 5, body cap 9 is enclosed within outside the O RunddichtringO 10, and O RunddichtringO 10 is enclosed within outside the top board 11; The top of valve body 3 links to each other with piston 5 tops, and valve body 3 bottoms link to each other with diaphragm 1.Seal ring 4 links to each other with the piston bottom.Stopper 2 links to each other with valve body 3.
The advantage of a kind of pneumatic valve device of the utility model is: utilize the piston motion principle to drive that diaphragm produces tension force and the purpose that reaches automatic interpolation water is effectively simple, operate steadily; Save considerable economic to the client; Structure is simpler, and need not people's operation, uses continuity very good; Rate of fault also can reduce greatly, and cost is little.
A kind of pneumatic valve device of the utility model is achieved in that when needs add water; The interface gives pneumatic valve through the modulating valve air inlet can for a prompting; Gas can produce a kind of power in valve body, can pass to piston (5) then, and piston (5) can move through big little spring (6), (7); Piston can drive following mandrel (8) and move upward; And mandrel (8) drives diaphragm through screw and upwards produces a kind of power, and water drives piston motion through the air inlet that does not stop and drives the automatic interpolation function that diaphragm is accomplished water just through the flowing of valve seat nature.
