Abstract
The utility model relates to a workpiece vacuumizing and vacuum back-filling system for a thin-shelled container. The workpiece vacuumizing and vacuum back-filling system solves the problem that a workpiece is damaged due to the internal and external pressure difference of the workpiece during the vacuumizing and vacuum back-filling system of the thin-shelled container. A workpiece (2) is arranged in a vacuum chamber (1), a communicating valve (4) arranged outside the vacuum chamber (1) is respectively connected with the workpiece (2), the vacuum chamber (1) and a station valve (5), the vacuum chamber (1) is connected with a pump-out valve (3) and a vacuum back-filling valve (7) which are arranged outside the vacuum chamber (1), and the pump-out valve (3) is connected with a vacuum valve (6).
Description
technical field:
The utility model relate in shell container case vacuumize, leak detection, backfill system.
background technology:
For vacuum helium leak test, vacuumize and the backfill vacuum link that is absolutely necessary, but for shell container, traditional workpiece and vacuum tank independently vacuumize respectively and backfill vacuum, vacuum tank volume and workpiece volume are variant, vacuum tank return pump and workpiece return pump pumping speed are variant, vacuum tank vacuum backfill valve and workpiece air release backfill speed difference, therefore shell container workpiece inside and outside differential pressure is uncontrollable, and shell container bearing capacity is poor, General Requirements container inside and outside differential pressure all will be controlled at certain scope, therefore the tradition backfilling process of finding time is easy to cause measured workpiece to damage cannot to use.
utility model content:
The purpose of this utility model be to provide a kind of prevent shell container workpiece in backfill vacuum process because of vacuum tank in workpiece in the shell container workpiece of the deformed damaged that causes of pressure reduction vacuumize and vacuum backfill system.
The utility model is achieved in that
Shell container workpiece vacuumizes and vacuum backfill system, workpiece 2 is placed in vacuum tank 1, at vacuum tank, have coupling cock 4 to be connected with workpiece, vacuum tank and station valve 5 respectively outward, vacuum tank is connected with its outer evacuation valve 3, vacuum backfill valve 7, and evacuation valve is connected with vacuum pump 6.
The mouth of finding time of workpiece 2 is connected with the non-tight valve plate end interface of coupling cock 4, and vacuum tank 1 is connected with the sealing valve plate end of coupling cock 4.
The utility model has the following advantages:
1, at the workpiece place of finding time mouthful, a coupling cock is installed, at the vacuum tank Shi Jiang UNICOM valve open of finding time, so just by workpiece volume and vacuum tank volume UNICOM, make inside workpiece and vacuum tank inner chamber form a volume, when finding time, workpiece inside and outside differential pressure is just effectively controlled, can control workpiece inside and outside differential pressure in certain scope, prevented shell container workpiece in vacuum because of in vacuum tank with workpiece in the deformed damaged that causes of pressure reduction.
2, when workpiece is done concerned process steps action, coupling cock, in closed condition, disconnects vacuum tank volume and workpiece volume, makes shell container workpiece in autonomous container state.
3, after workpiece leak detection recovery finishes, station valve cuts out, coupling cock is opened, vacuum tank inner chamber and workpiece lumen are connected as a single entity, and do together vacuum backfill, and when backfill, workpiece inside and outside differential pressure can be controlled effectively like this, can control workpiece inside and outside differential pressure in certain scope, prevented shell container workpiece in backfill vacuum process because of vacuum tank in workpiece in the deformed damaged that causes of pressure reduction.
accompanying drawing explanation:
Fig. 1 is the utility model structural drawing.
embodiment:
The utility model is comprised of shell container workpiece, vacuum tank, UNICOM's valve, backfill vacuum valve, the valve of finding time, return pump group, station valve, workpiece 2 is placed in vacuum tank 1, at vacuum tank, there is coupling cock 4 to be connected with workpiece, vacuum tank and station valve 5 respectively outward, vacuum tank is connected with its outer evacuation valve 3, vacuum backfill valve 7, and evacuation valve is connected with vacuum pump 6.
The door-plate of vacuum tank 18 is opened, workpiece 2 is positioned in vacuum tank 1, the mouth of finding time of workpiece 2 is connected with the non-tight valve plate end interface of coupling cock 4, close door-plate 8, vacuum tank 1 is connected with coupling cock 4 sealing valve plate ends, coupling cock place 4 is in opening, station valve 5 and the workpiece mouthful UNICOM of finding time, station valve 5 is in closed condition, vacuum backfill valve 7 cuts out, vacuum tank 1 is closed sealing, vacuum pump 6 starts, evacuation valve 3 is opened, now workpiece 2 together with vacuum tank 1 in by vacuum pump 6 evacuated, be evacuated to the vacuum tightness of workpiece demand, close coupling cock 4, open station valve 5, now workpiece can carry out concerned process steps work, workpiece 2 leak detections are closed station valve 5 after having reclaimed, and open coupling cock 4, workpiece 2 and vacuum tank 1 UNICOM, and evacuation valve 3, in closed condition, is opened vacuum backfill valve 7, to vacuum tank and workpiece backfill simultaneously, after backfill, opens door-plate 8.
