Description
Technical field
The present invention relates to a kind of blind plates, more particularly, to 8 word blind plates of big-diameter pipeline.
Background technique
8 word blind plates are a kind of pipeline appliances, primarily to convenient to overhaul, structure is half blind plate half iron ring.Often
For needing to change the pipeline flange of process, material mainly has carbon steel, and stainless steel, alloy can be according to loine pressure grade and pipe
Road medium is selected.It is commonly available to the more susceptible to plugging pipeline of medium.However, traditional blind plate, especially nominal diameter,
The biggish blind plate weight of nominal pressure is larger, more then over one hundred jin, and blind plate switching could be completed by needing more people to operate simultaneously, time-consuming to take
Power.
Summary of the invention
The present invention provides a kind of 8 word blind plates to solve above-mentioned technical problem, it is therefore an objective to save manpower, improve work effect
Rate, it is time saving and energy saving, it is easy to switch, improves stability, structure is simple, is suitable for industrial production.
A kind of 8 word blind plates of the present invention for the above-mentioned purpose, including closed end blind plate and flowing end blind plate, closed end blind plate and
It flows and is connected between the blind plate of end by connecting rod, be equipped with central axis at the middle part of connecting rod, central axis is fixed on bracket.
Central axis is ball bearing.
Closed end blind plate and flowing end blind plate and connecting rod are welded, and weld bead height is thin pieces thickness in two adjacent weldments.
Closed end blind plate and flowing end blind plate are equipped with bolt hole.
Bracket is two sets of door shaped stents, is respectively provided at closed end blind plate and flows the two sides of end blind plate, the length of central axis
Equal to the distance of two sets of door shaped stents.
Connecting rod is steel plate, the thickness of the thickness need≤closed end blind plate of connecting rod, and closed end blind plate thickness is identical.
Advantages of the present invention effect: the present invention has fully considered the operability when switching of 8 word blind plates, saves manpower, mentions
High working efficiency, it is time saving and energy saving, it is easy to switch, high stability, structure is simple, especially suitable for industrial production.
Detailed description of the invention
Fig. 1 is main view of the invention.
Fig. 2 is the top view of Fig. 1.
In figure: 1, closed end blind plate；2, end blind plate is flowed；3, bracket；4, central axis；5, connecting rod；6, bolt hole；7, it manages
Road.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings, and preferred embodiment described herein is merely to illustrate reconciliation
The present invention is released, is not intended to limit the present invention.
As shown, the present invention 8 word blind plates of one kind, including closed end blind plate 1 and flowing end blind plate 2,1 He of closed end blind plate
It is connected between flowing end blind plate 2 by connecting rod 5, is equipped with central axis 4 at the middle part of connecting rod 5, central axis 4 is fixed on bracket 3
On.
Central axis 4 is ball bearing.
Closed end blind plate 1 and flowing end blind plate 2 and connecting rod 5 are welded, and weld bead height is thin pieces thickness in two adjacent weldments.
Closed end blind plate 1 and flowing end blind plate 2 are equipped with bolt hole 6.
Closed end blind plate 1 and flowing 2 central junction line of end blind plate are in 180 degree.Bracket 3 is two sets of door shaped stents, is set respectively
The two sides of blind plate and flowing end blind plate in closed end, the length of central axis 4 are equal to the distance of two sets of door shaped stents.
Connecting rod is steel plate, the thickness of the thickness need≤closed end blind plate of connecting rod, and closed end blind plate thickness is identical.
Working principle of the present invention: when needing to switch 8 word blind plate, slurry in pipeline 7 need to be stopped expecting, and the material in blow-down pipe
Slurry, when preventing switching blind plate, slurry overflow pipe.Bolt in bolt hole 6 is unclamped one by one, an operative employee buttresses blind
Plate makes bolt after the extraction of bolt hole 6, and blind plate is unlikely to rotate around central axis 4, and another operative employee is by bolt from bolt hole 6
Middle extraction, blind plate is rotated 180 ° around central axis 4 by the operative employee for buttressing closed end blind plate or flowing end blind plate at this time, by bolt hole
6 and flange screw hole alignment, another operative employee select 2-4 bolt hole, bolt be first inserted into bolt hole, blind plate is in axial side
To being fixed, two operative employees can install the bolt of remaining bolt hole simultaneously, and flange is fixed with blind plate, complete closed end blind plate
With the switching of flowing end blind plate.Flange is that same pipeline welds together, and weld bead height is thin pieces thickness in two adjacent weldments, no
It needs to operate on it.Bracket 3 plays fixed center axis 4 and closed end blind plate and flowing end in whole flow process handoff procedure
The effect of blind plate.
