Abstract
The invention discloses a flange for a coaxial acid-base-resisting self-sucking pump. The flange comprises a flange body, a first acid-base-resisting flange sleeve, a second acid-base-resisting flange sleeve, lubricant injection holes and self-weight reducing through holes. The first acid-base-resisting flange sleeve is arranged on the inner surface of the flange body. The second acid-base-resisting flange sleeve is arranged on the outer surface of the flange body. The lubricant injection holes are formed in the first acid-base-resisting flange sleeve in a sleeving mode. The self-weight reducing through holes are formed in the flange body. In the way, the acid-base-resisting performance is good, self lubricating can be achieved, self weight is low, and convenience is brought to practical application.
Description
Technical field
The present invention relates to flange field, particularly relate to a kind of for coaxial acid resistant alkali self-priming pump flange.
Background technique
Flange, pad and bolt three form dismountable linkage structure in pipeline, and very universal in pressure piping is also a kind of very important Connecting format.Usually, flange, bolt and pad three form a sealing pair jointly, and three's acting in conjunction, supplements and complements each other, the excellent sealing of guarantee joint.Flange is the benchmark piece determining pipeline nominal pressure grade.The kind of flange is a lot, the flange of different types, and its sealability is different, and applicable situation is also different.
But the acid-proof alkaline of the flange used at present is poor, can not realize selflubricating, and from heavy, bring inconvenience to practical application.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one for coaxial acid resistant alkali self-priming pump flange, and acid-proof alkaline is good, can realize selflubricating, and from heavy and light, brings conveniently to practical application.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of for coaxial acid resistant alkali self-priming pump flange, comprise: flange body, first acid resistant alkali flange sleeve, second acid resistant alkali flange sleeve, oiling agent hand-hole and alleviate deadweight through hole, the internal surface of described flange body is provided with the first described acid resistant alkali flange sleeve, the outer surface of described flange body is provided with the second described acid resistant alkali flange sleeve, the first described acid resistant alkali flange sleeve is provided with multiple described oiling agent hand-hole, described flange body is provided with and multiplely described alleviates deadweight through hole.
In a preferred embodiment of the present invention, the number of described oiling agent hand-hole is 4 or 6.
In a preferred embodiment of the present invention, the described number alleviating deadweight through hole is 4,6 or 8.
In a preferred embodiment of the present invention, the described aperture alleviating deadweight through hole is 0.3 ~ 0.6cm.
The invention has the beneficial effects as follows: acid-proof alkaline of the present invention is good, can selflubricating be realized, and from heavy and light, bring conveniently to practical application.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the present invention for the preferred embodiment of coaxial acid resistant alkali self-priming pump flange one;
In accompanying drawing, the mark of each parts is as follows: 1, flange body, the 2, first acid resistant alkali flange sleeve, the 3, second acid resistant alkali flange sleeve, and 4, oiling agent hand-hole, 5, alleviate deadweight through hole.
Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of for coaxial acid resistant alkali self-priming pump flange, comprise: flange body 1, first acid resistant alkali flange sleeve 2, second acid resistant alkali flange sleeve 3, oiling agent hand-hole 4 and alleviate deadweight through hole 5, the internal surface of described flange body 1 is provided with the first described acid resistant alkali flange sleeve 2, the outer surface of described flange body 1 is provided with the second described acid resistant alkali flange sleeve 3, the first described acid resistant alkali flange sleeve 2 is provided with multiple described oiling agent hand-hole 4, described flange body 1 is provided with and multiplely described alleviates deadweight through hole 5.
In the present invention, the number of described oiling agent hand-hole 4 is 4 or 6.
In the present invention, the described number alleviating deadweight through hole 5 is 4,6 or 8.
In the present invention, the described aperture alleviating deadweight through hole 5 is 0.3 ~ 0.6cm.
The beneficial effect that the present invention is used for coaxial acid resistant alkali self-priming pump flange is: acid-proof alkaline of the present invention is good, can realize selflubricating, and from heavy and light, brings conveniently to practical application.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
