Abstract
The utility model discloses a vacuum pipeline connecting device. The vacuum pipeline connecting device comprises a corrugated tube, a horizontal bin body base plate, and a vertical bin body door panel higher than the bin body base plate, wherein a lower portion of the bin body door panel is provided with a horizontal upper flange connected with a vertical inlet air tube. An upper side of the bin body base plate is provided with a horizontal transition flange provided with a vertical outlet air tube, the vertical air tube penetrates downwards through the bin body base plate, and two sides of the transition flange in the length direction are respectively provided with a vertical air cylinder. An upward-extending cylinder rod of each air cylinder is connected with a lower side of a horizontal lower flange. The corrugated tube is connected between the lower flange and the transition flange, and the corrugated tube is downwards communicated with the outlet air tube. When the vacuum pipeline connecting device is in use, the cylinder rod pushes the lower flange upwards to enable the lower flange to be in sealing contact with the upper flange, so the inlet air tube is communicated with the corrugated tube; the cylinder rod pulls the lower flange downwards to enable the lower flange to be out of contact with the upper flange, so the inlet air tube is separated from the corrugated tube. The vacuum pipeline connecting device can be widely used in equipment with a gas channel which frequently needs disconnection or frequently needs to be moved and dislocated in a large angle.
Description
Technical field
The utility model provides a kind of vacuum pipe connection set.
Background technique
At present; Vacuumize to be generally between the pipeline of usefulness and expose and bellows that length is long connects; Especially in the vacuum pumping device of vacuum bin, have following defective in the using process: bellows at some such as break-make often, wide-angle or move in the gas circuit of dislocation, break-make in enormous quantities often bending and long yielding, the damage of bellows significantly significantly; The working life of bellows is shorter, and this brings certain potential risk to safety in production.In addition, the workload of bellows repair and replacement greatly, comparatively the trouble, user cost is also higher.
The model utility content
The technical problem that the utility model will solve provides a kind of vacuum pipe connection set reliable and stable, that working life is long that uses.
For solving the problems of the technologies described above, the vacuum pipe connection set that the utility model provides, it comprises bellows, horizontal warehouse base plate, is higher than the vertical warehouse door-plate of warehouse base plate; The bottom of warehouse door-plate is provided with the horizontal upper flange that is connected to vertical suction tude; The upside of warehouse base plate is provided with the horizontal transition flange of vertical steam outlet pipe; Wear the warehouse base plate under the steam outlet pipe; The length direction both sides of counter flange respectively are provided with a vertical cylinder; Stretch the cylinder bar on each cylinder and all join with the downside of horizontal lower flange, bellows is connected between lower flange and the counter flange, and bellows is communicated with steam outlet pipe down;
During use, top lower flange on the cylinder bar lets the sealing of lower flange and upper flange contact, so that suction tude, bellows, steam outlet pipe are connected; The drop-down lower flange of cylinder bar lets lower flange and upper flange disengage, so that suction tude, bellows are broken off mutually.
For can concise description for the purpose of the problem, below the said vacuum pipe connection set of the utility model be all abbreviated as this device.
The beneficial effect of the utility model is: bellows can break off as required with suction tude and being connected.When the disconnection of needs gas circuit, wide-angle or mobile significantly the dislocation, when for example opening the bin door, utilize cylinder that suction tude is broken off with bellows mutually, like this, bellows need yet just can not cause distortion, damage along with moving, reversing to bellows when opening the door; When the connection of needs gas circuit, wide-angle or mobile significantly dislocation finish, utilize cylinder that suction tude and bellows are communicated with, can make that gas circuit is unimpeded, realize the break-make rapidly and efficiently of vacuum pipe, therefore, the use of this device is reliable and stable, working life is longer; Significantly reduce the big workload of bringing owing to the bellows repair and replacement, user cost is low, has reduced cost of production.
Gas circuit, gas circuit that this device can be widely used in often needs disconnection need frequent wide-angle to move on the equipment of dislocation.
Description of drawings
Fig. 1 is the plan view of this device.
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.It is to be noted: the schematic representation that Fig. 1, Fig. 2 represent when being this device gas circuit connected state.
This device comprises bellows 1, horizontal warehouse base plate A, is higher than the vertical warehouse door-plate B of warehouse base plate A, and the bottom of warehouse door-plate B is provided with the horizontal upper flange 4 that is connected to vertical suction tude 2; The upside of warehouse base plate A is provided with the horizontal transition flange 6 of vertical steam outlet pipe 3; Steam outlet pipe is worn warehouse base plate A for 3 times; The length direction both sides left and right symmetrically of counter flange 6 respectively is provided with a vertical cylinder 7; Stretch cylinder bar 71 on each cylinder 7 and all join with the downside of horizontal lower flange 5, bellows 1 is connected between lower flange 5 and the counter flange 6, and bellows 1 time is communicated with steam outlet pipe 3.
Close bin door-plate B, in the time of need vacuumizing bin, make top lower flange 5 on the cylinder bar 71, let 4 sealings of lower flange 5 and upper flange contact, so that suction tude 2, bellows 1 be connected, can vacuumize to the greatest extent; In the time of need opening bin door-plate B; Make cylinder bar 71 drop-down lower flanges 5; Let lower flange 5 and upper flange 4 break away from, so that suction tude 2, bellows 1 break off mutually, at this moment open bin door-plate B; Bellows 1 promptly can not followed moving of bin door-plate B and be moved, reverses, and yet just can not cause distortion, damage bellows 1.
Gas circuit, gas circuit that this device can be widely used in often needs disconnection need frequent wide-angle to move on the equipment of dislocation.
Above-described only is a kind of mode of execution of the utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make conspicuous some conversion or alternative and remodeling, these also should be regarded as belonging to the protection domain of the utility model.
