Description
Technical field
The utility model relates to a kind of vacuum equipment, more specifically to a kind of vacuum tank that can observe the band view window of equipment operation situation in the tank body.
Background technology
Existing vacuum tank, its structure generally includes tank body and cover, rotating being fixed on the tank body of said cover one end, cover covers on the tank body opening.
The vacuum tank that is used for high voltage power distribution switch manufacturing is an important switch leak detection checkout equipment.When cover with after the tank body opening sealing, be to vacuumizing in the tank body, and then charge into the SF6 insulating gas.Because the casing of gas tank generally is welded by 2～3mm thin plate (corrosion resistant plate); Pressure differential≤the 0.6bar of its design; Vacuum pumping process under conventional 1 atmospheric pressure (1bar) is because inside and outside differential pressure big (1 atmospheric pressure of up) causes the casing of gas tank to produce distortion easily.Therefore need gas tank be placed in the shape vacuum tank of garden, vacuumize simultaneously in the vacuum tank and in the casing of gas tank.
Owing in the vacuum in the tank body some emergency conditioies may take place, but tank body and cover all are opaque, and there are not parts can let the equipment operation situation of people in the vacuum tank viewed tank body.Therefore after in case cover is shut, what's going in the tank body no matter, we cannot see, and in a single day the user just can't understand the situation in the tank body very first time like this, so the emergency condition user is taken place and just be difficult to tackle timely, deal with problems.
Summary of the invention
The utility model technical matters to be solved provides a kind of vacuum tank with view window, and the vacuum tank of this band view window can let equipment operation situation in user's Direct observation tank body.The technical scheme that adopts is following:
A kind of vacuum tank with view window comprises tank body and cover, rotating being fixed on the tank body of said cover one end; It is characterized in that: also comprise view window; Said cover has through hole, and said view window is fixed on the cover outside surface, and view window covers on the through hole of cover outside surface.The user sees through view window can Real Time Observation arrive equipment operation situation in the tank body.
A kind of more excellent scheme; Said view window comprises fixed frame and explosion-proof transparency glass plate, and fixed frame simultaneously has locating slot, and another side has viewport; Viewport is communicated with locating slot; Said explosion-proof transparency glass plate is placed in the locating slot, and fixed frame is fixed on the cover outside surface, and explosion-proof transparency glass plate is pressed on the through hole of cover outside surface.
In order better to play anti-gas-leak and explosion-proof purpose, said view window also comprises sealing ring, and two sides of said sealing ring closely contact with the right flank of explosion-proof transparency glass plate and the bottom surface of locating slot respectively.
A kind of more excellent scheme, said fixed frame is circular, and said sealing ring is circular, and said explosion-proof transparency glass plate is in the form of annular discs.
Said view window also comprises at least three screws, and said fixed frame has at least three screw holes, and the number of screw is identical with the number of screw hole, and screw is corresponding one by one with screw hole, and each screw passes corresponding screw hole and pierces in the cover.
For with firm being fixed on the cover outside surface of fixed frame, preferable scheme, said each screw hole lays respectively at the edge of fixed frame, and each screw hole circumferentially is arranged in order along fixed frame.
Better scheme, said each screw hole circumferentially evenly distributes along fixed frame.
Preferred scheme, the number of said screw hole is six.
The utility model beneficial effect against existing technologies is; Owing to set up view window, so the user can observe equipment operation situation in the tank body, and the user can understand the situation in the tank body in real time; Therefore in a single day the emergency condition user being taken place and just can tackle timely, and deals with problems.

Embodiment
Shown in Fig. 1-5, the vacuum tank of the band view window in this preferred embodiment comprises tank body 1 and cover 2, and said cover 2 one ends are rotating to be fixed on the tank body 1, comprises view window 3 in addition.
Said cover 2 has through hole 201, and said view window 3 is fixed on cover 2 outside surfaces, and view window 3 covers on the through hole 201 of cover 2 outside surfaces.
Said view window 3 comprises fixed frame 301 and explosion-proof transparency glass plate 302; Fixed frame 301 one sides have locating slot 3011; Another side has viewport 3012, and viewport 3012 is communicated with locating slot 3011, and said explosion-proof transparency glass plate 302 is placed in the locating slot 3011; Fixed frame 301 is fixed on cover 2 outside surfaces, and explosion-proof transparency glass plate 302 is pressed on the through hole 201 of cover 2 outside surfaces.
