Abstract
The utility model discloses a large compressor air cylinder CO seal structure which comprises a cylinder body (1), a cylinder sleeve (2) and a cylinder cover (3), wherein the end faces (4a) of the cylinder body (1) and the cylinder sleeve (2) are provided with downwards concave step surfaces (4b). The cylinder cover (3) is provided with protrusions (5) which are stretched into the downwards concave positions of the cylinder body (1) and the cylinder sleeve (2), and a seal pad (6) is arranged between the end faces of the protrusions (5) and the downwards concave step surfaces (4b). On the condition that the large compressor air cylinder CO seal structure meets requirements of seal performance, the seal structure is simplified, and installation is convenient.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly relates to a kind of sealing configuration for hermetic compressor CO.
Background technique
In the process of CO large-scale compressor work, very strict to toxic gas CO seal request, therefore need to carry out particular design to CO large-scale compressor cylinder seal.In prior art, the seal ring that arranges between large-scale compressor cylinder body and cylinder cap, often the relative cylinder diameter of overall dimensions is larger, and the sealing gasket radial height is larger, causes the sealing gasket specific pressure less, causes the sealing effect variation, thus the Security of impact start.
Therefore those skilled in the art are devoted to develop a kind of large-scale compressor cylinder CO sealing configuration simple in structure, easy for installation.
The model utility content
Because the defects of prior art, technical problem to be solved in the utility model is to provide a kind of large-scale compressor cylinder CO sealing configuration simple in structure, easy for installation.
For achieving the above object, the utility model provides a kind of large-scale compressor cylinder CO sealing configuration, comprises cylinder body, cylinder sleeve and cylinder cap; The end of described cylinder body and cylinder sleeve is provided with recessed step surface; Described cylinder cap is provided with projection; Described projection stretches into the lower recess of described cylinder body and cylinder sleeve; Be provided with flat sealing gasket between the end face of described projection and described step surface.
Better, the distance between the end face of described step surface and described cylinder body and cylinder sleeve is 8mm; The projection amount of described projection is 7mm; The thickness of described sealing gasket is 3mm.
Better, sealing pad footpath overall dimensions is more bigger than cylinder diameter, and radial height is less, and therefore under same pretightening force, specific pressure is larger.
The beneficial effects of the utility model are: the utility model has been simplified sealing configuration satisfying under the prerequisite of sealability, and easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the partial enlarged drawing at I place in Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, a kind of large-scale compressor cylinder CO sealing configuration comprises cylinder body 1, cylinder sleeve 2 and cylinder cap 3.The end face 4a place of cylinder body 1 and cylinder sleeve 2 is provided with recessed step surface 4b, and cylinder cap 3 is provided with projection 5.Projection 5 stretches into the lower recess of cylinder body 1 and cylinder sleeve 2, is provided with flat sealing gasket 6 between the end face of projection 5 and step surface 4b.
Distance L 1 between the end face 4a of step surface 4b and cylinder body 1 and cylinder sleeve 2 is 8mm; The projection amount L2 of projection 5 is 7mm; The thickness of sealing gasket 6 is 3mm.
But with regard to sealing effect, O-ring seals is generally effective than flat sealing gasket, but for large-scale workpiece, plain cushion can satisfy seal request fully.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
