Abstract
The utility model relates to a swing vacuum pneumatic valve, which is composed of a valve body, a valve seat, a valve core, a swing rod, a swing gas cylinder, and other portions. The swing vacuum pneumatic valve can drive the swing rod and the valve core through the swing gas cylinder; when the swing vacuum pneumatic valve is opened or closed, the differential pressure of the two ends can be formed, or the sealing of the vacuum system is maintained. Compared with the old-typed vacuum turnover plate valve, the swing vacuum pneumatic valve has the advantages of simple structure, reliable work, and low manufacturing cost. The sealing performance of the swing vacuum pneumatic valve is also superior to an automatic non-return valve.
Description
The utility model relates to a kind of pneumatic valve, particularly a kind of swing type Pneumatic vacuum valve.
In the past, the automatic check valve that is adopted in steel works ladle refining water vapor airless injection system was the automatic open and close of pressured difference.But the reliable in action of the Pneumatic vacuum valve of this differential structure is poor, sealability is also undesirable, so that influences the whole system operation quality.
The purpose of this utility model provides that a kind of open and close is reliable, the swing type Pneumatic vacuum valve of good seal performance.
The solution that realizes the utility model purpose is: the swing type Pneumatic vacuum valve that is provided has valve body, valve seat and spool, is provided with an oscillating cylinder on valve body, and the output revolving shaft of oscillating cylinder extends in the valve body, and links by fork and spool.The working principle of this pneumatic valve is: utilize output revolving shaft positive and negative of oscillating cylinder to transfer and drive the fork swing, move thereby drive spool, realize the unlatching of valve or close.
The utility model adopts the open and close power of oscillating cylinder as valve, so action is very reliable.Be pressed on the valve seat after the spool closure, thereby good seal performance.In addition, the structure of this pneumatic valve also vacuum Flap valve than old-fashioned is simple, and cost is also lower.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is an embodiment's of the utility model a plan view.
Fig. 2 is the sectional view at Figure 1A-A place.
Fig. 3 is the plan view of Fig. 1.
As Fig. 1～shown in Figure 3: there is flange at the two ends of valve body 1, are used for linking with vacuum system.Valve seat 2 can be pulled down, so that the processing of valve body, assembling and maintenance.Oscillating cylinder 5 connects firmly on valve body 1, and its rotating shaft 6 is stretched in the valve body 1.Adopt JO type vacuum rubber combined seal ring between rotating shaft 6 and the valve body, to guarantee the sealing of valve body.One end of fork 3 connects by key and rotating shaft 6, and the other end is connected with spool 4.When the rotating shaft 6 of oscillating cylinder is just being changeed, drive spool 4 by fork 3 and lift off a seat 2(shown in Fig. 1 dot and dash line), valve opening; Otherwise, valve closing.
The pneumatic working pressure of this example pneumatic valve: 0.15-0.16MPa; Degree of vacuum: 10
-2Pa; Operating temperature :-10-80 ℃.This pneumatic valve is mainly used in ladle refining water vapor airless injection pumping system, also can be used for other vacuum system.
