Embodiment
In order to understand the present invention better, the present invention is done to describe further below in conjunction with accompanying drawing.
As shown in Figure 1, small vacuum filling device of the present invention is made up of three parts, comprise filling valve, closed conduit spanner, T-valve door pipeline, filling valve mainly is made of valve matrix 1, valve rod 2, cylindrical seal body 3, anti-sliding lid 4, valve matrix 1 is shaped as H shape, have screw thread in the middle of its cross wall, valve matrix 1 is connected with valve rod 2 by the screw thread of its cross wall, and valve rod 2 lower ends and cylindrical seal body 3 upper ends fuse; The outer circumferential face of cylindrical seal body 3 contacts with the inside sidewalls of valve matrix 1, the cross wall of the valve matrix 1 of cylindrical seal body 3 tops has first group of bottled gas blowhole 5, below valve matrix 1 sidewall, have second group of bottled gas blowhole 6, valve matrix 1 side wall lower ends welding anti-sliding lid 4; The closed conduit spanner is shaped as elbow-shaped, and its underpart inwall has spanner internal thread 10, and spanner internal thread 10 is threaded with valve matrix 1 sidewall top outer surface, and the connecting tube 15 of closed conduit spanner front end and T-valve door pipeline welds together; There is a cylindrical body 11 closed conduit spanner corner, cylindrical body 11 lower ends and valve rod 2 upper end clampings.
T-valve door pipeline is identical with conventional valve pipe, and 19,20,21, four connecting tubes 15,16,17,18 of three pipeline valves are arranged.
After 1 cast inblock of valve matrix, the machining moulding; Valve rod 2 and cylindrical seal body 3 directly utilize machining to form, after machining, cover upper sealing washer 7 on the valve rod 2, be contained on the valve matrix 1 from valve matrix 1 bottom with valve rod 2 and cylindrical seal body 3, utilize screw-driver that the cross groove 9 of cylindrical seal body 3 lower ends is upwards tightened, and then anti-sliding lid 4 is welded on valve matrix 1 side wall lower ends, finish the basic processing of filling valve, the filling valve welded and installed is got final product on equipment.
When the present invention needs gas-filling or liquid and vacuumizes, the spanner internal thread 10 of closed conduit spanner underpart inwall is enclosed within on the screw thread of valve matrix 1 sidewall top outer surface, the rotary seal Pipe wrench, valve rod 2 is moved down, when second group of bottled gas blowhole 6 still sealed by cylindrical seal body 3, and when closed conduit spanner and valve matrix have reached enough seal degree, opening conduits valve 20 and 19, and the vacuum pump pump-line that connecting tube 16 and this device is outer is connected, start vacuum pump, the gas in connecting tube 18 and 15 is taken out; Close pipeline valve 20 and 19 then, close vacuum pump, vacuum pump and being connected of connecting tube 16 are removed, continue the rotary seal Pipe wrench, cylindrical seal body 3 is constantly descended, when second group of bottled gas blowhole 6 opened fully, and sidewall sealing platform 8 is closely contacted with spanner sealing platform 12, make the seal degree between closed conduit spanner and the filling valve reach the can requirement, again connecting tube 16 is connected with the vacuum pump pump-line, start vacuum pump, if can for the first time, then need opening conduits valve 20 and 19, equipment is evacuated, and keep a period of time, close pipeline valve 19 then, the container that the can medium is housed is connected with connecting tube 17, and opening conduits valve 21 and 20 allows vacuum pump work a little while again, other gas that is equipped with between the container of can medium and the connecting tube and vessel surface exists is taken away, close pipeline valve 20 then, opening conduits valve 19, beginning can.Can is closed pipeline valve 19,21 earlier, opening conduits valve 20 after finishing, start vacuum pump, work is discharged to the outside with can medium remaining in the pipeline a little while, then, close vacuum pump, close all pipeline valves, remove connecting tube 17 with 16 with extraneous being connected, the rotary seal Pipe wrench, in the process of rotation, cylindrical seal body 3 at first can be closed sealing with second group of bottled gas blowhole 6, at last first group of bottled gas blowhole 5 closed sealing, cannedly so just finished.
The present invention has been owing to cancelled by the valve on the filling apparatus pipeline, and adopts double seal, increased the sealability of device, and the device uptime is prolonged; In addition, the present invention has reduced the manufacturing expense of equipment, has prevented contingent leakage, makes can easy, and is easy for installation, is fit to the can of mini-plant.
