Abstract
Description
Technical field
The present invention relates to a kind of blind plate.
Background technique
Blind plate is called blind flange, what have is also called blind flange, it is middle flange not with holes, the function played is the same with end socket and pipe cap, only blind plate sealing is a kind of removable seal arrangement, and the sealing of end socket does not prepare to open again, the form kind of sealing surface is more, has plane, convex surface, male and fomale(M&F) and ring joint face.Its isolation of blind plate, cutting action are the same with end socket, pipe cap, welding plug role, due to its good seal performance, for the system needing Secure isolation, generally all as reliable isolating means.Sealing and the isolation performance of the blind plate of present use are poor, well can not isolate, reduce isolation effect.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of sealing and the good blind plate of isolation performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of blind plate, there is blind plate body, the corner, plate face of described blind plate body is provided with circular groove, circular groove is arranged installation through hole, the surface spraying of blind plate body has carbon steel sprayfused coating.
Further, described blind plate body adopts Wear-resistant alloy steel material to make.
Further, the diameter of described circular groove is greater than the diameter installing through hole.
Further, the surface hardness of described blind plate body is HRC >=50.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to use, has good sealing and isolation performance, increases work efficiency, increase wear-resisting property, increase the service life, reduce cost of production.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is left view of the present invention.
1. blind plate body, 2. circular grooves in figure, 3. install through hole, 4. sprayfused coating.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, a kind of blind plate shown in 2, there is blind plate body 1, the corner, plate face of blind plate body 1 is provided with circular groove 2, the corner of blind plate body 1 is provided with circular groove 2 and can better improves sealing effect and barriering effect, fixed performance is installed simultaneously good, can not produce and rock, circular groove 2 is arranged through hole 3 is installed, the diameter of circular groove 2 is greater than the diameter installing through hole 3, the surface spraying of blind plate body 1 has carbon steel sprayfused coating 4, blind plate body 1 adopts Wear-resistant alloy steel material to make, the surface hardness of blind plate body 1 is HRC >=50, need not often change, improve the working efficiency of pebble mill, reduce cost of production, alleviate the labor intensity of staff.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
