Abstract
The invention discloses a novel pump cover. The novel pump cover is characterized by comprising a groove, a middle connecting part and an outer cover body which are integrally formed by casting from inside to outside, the thickness of the middle connecting part is larger than the thicknesses of the groove and the outer cover body, gasket fixing holes are formed in the outer cover body, a gasket provided with an anticorrosive layer is arranged on the groove, the middle connecting part and the outer cover body through the gasket fixing holes in a detachable mode, the outer cover body is provided with two or more protrusions which extend outwards, pump cover fixing holes are formed in the protrusions, the groove is in a circular shape, and the middle connecting part is in an annular shape. The novel pump cover is provided with the gasket which is detachable and has an anticorrosive function, the structural design is reasonable, the use is flexible, and the seal performance is good.
Description
Technical field
The present invention relates to a kind of Novel pump cover.
Background technique
Traditional pump cover structure is heavier, and also needs to carry out the process such as anticorrosion to prevent from being corroded, and uses underaction.
Summary of the invention
For the problems referred to above, the invention provides a kind of Novel pump cover, be provided with the pad dismountable, there is anti-corrosion function, reasonable in design, use flexibly and good seal performance.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of Novel pump cover, it is characterized in that, comprise all-in-one-piece groove of casting from inside to outside, middle interconnecting piece and outside lid, the thickness of described middle interconnecting piece is greater than the thickness of groove and the thickness of outside lid, described outside lid is provided with pad fixed hole, one pad being provided with anticorrosive coat is arranged on groove by pad fixed hole is dismountable, on middle interconnecting piece and outside lid, described outside lid is also provided with at least two projections extended laterally, pump cover fixed hole is provided with in described projection, described groove is rounded, described middle interconnecting piece ringwise.
Preferably, the aperture of described pad fixed hole is less than the aperture of pump cover fixed hole.
Preferably, described pump cover is stainless steel.
Preferably, described outside lid is also provided with can with the bayonet socket of pump phase clamping.
By reasonably designing shape and the thickness of groove, middle interconnecting piece and outside lid, make relatively simple for structure, pump cover is without the need to carrying out preservative treatment, can select whether pad is set as required, when arranging pad, pump cover not only has anti-corrosion function and sealability is better, uses more flexible.Further, connection is more firm.
The invention has the beneficial effects as follows: be provided with the pad dismountable, there is anti-corrosion function, reasonable in design, use flexibly and good seal performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Novel pump cover of the present invention;
The mark implication of accompanying drawing is as follows:
1: outside lid; 2: pad fixed hole; 3: pump cover fixed hole; 4: bayonet socket; 5: projection; 6: groove; 7: middle interconnecting piece.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
A kind of Novel pump cover, as shown in Figure 1, comprise cast from inside to outside all-in-one-piece groove 6, middle interconnecting piece 7 and outside lid 1, wherein, described groove 6 is rounded, described middle interconnecting piece 7 ringwise, this kind of structural symmetry is best, the dismounting of more convenient follow-up pad and installation, and sealability is also best, and overall pump cover can adopt stainless steel, without the need to carrying out preservative treatment.The thickness of described middle interconnecting piece 7 is greater than the thickness of groove 6 and the thickness of outside lid 1, keeps flat by pump cover, and the height of middle interconnecting piece 7 is greater than the height of groove 6 and the height of outside lid 1.
Described outside lid 1 is provided with pad fixed hole 2, one pad being provided with anticorrosive coat is arranged on groove 6, middle interconnecting piece 7 and outside lid 1 by pad fixed hole 2 is dismountable, described outside lid 1 is also provided with at least two projections extended laterally 5, in described projection 5, is provided with pump cover fixed hole 3.Generally speaking, the aperture of pad fixed hole 2 is less than the aperture of pump cover fixed hole 3.Preferably, described outside lid 1 is evenly provided with three projections extended laterally 5.
Preferably, described outside lid 1 is also provided with can with the bayonet socket 4 of pump phase clamping, described bayonet socket 4 is in inner large, outside little structure.
By reasonably designing shape and the thickness of groove, middle interconnecting piece and outside lid, make overall structure fairly simple, pump cover is without the need to carrying out preservative treatment, can select whether pad is set as required, when arranging pad, pump cover not only has anti-corrosion function and sealability is better, uses more flexible.Further, connection is more firm.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present invention.
