Abstract
The invention discloses a welded metal bellows seal with a moving ring and a stationary ring being interchangeable. A non-compensation ring, a bellows seal head, an end cover and a driving ring are sequentially arranged on the outer side of a shaft sleeve; the non-compensation ring is the same as a tailstock of the bellows seal head in structural dimension; parts of the shaft sleeve, positioned at the non-compensation ring and the tailstock, are the same as parts of the end cover, positioned at the non-compensation ring and the tailstock, in structural dimension; the positions of the non-compensation ring and the bellows seal head are interchangeable; when the bellows seal head is connected with the end cover, the bellows seal head acts as the moving ring, and the non-compensation ring acts as the stationary ring; and when the non-compensation ring is connected with the end cover, the non-compensation ring acts as the moving ring, and the bellows seal head acts as the stationary ring. The bellows seal has characteristics that the structure is simple, the assembly, the disassembly and the changing are convenient, the non-compensation ring and the tailstock of the bellows seal head are designed to be the same in structural dimension, the interchange positions of the moving ring and the stationary ring are achieved, the purpose of interconversion of a rotary type and a stationary type can be realized while the end cover and the shaft sleeve are not required to be redesigned, and the time and materials are saved.
Description
Technical field
The present invention relates to the mechanical sealing technology field, be specifically related to the interchangeable welded metal bellow sealing of a kind of dynamic and static ring.
Background technique
The welded metal bellow sealing is used very extensive at present; Mainly be divided into two kinds of rotary-type and statics because structural otherness, if scene need the general wherein a kind of pattern change another kind of pattern into; Must design end cap again, axle sleeve could be realized, promptly lose time and waste material.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, provide a kind of dynamic and static ring interchangeable welded metal bellow sealing.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: the interchangeable welded metal bellow sealing of a kind of dynamic and static ring; The axle sleeve outside that is sleeved on the axle is equipped with uncompensated ring, sylphon seal head, end cap, driving ring successively; On the said driving ring drive screw is installed, said drive screw is passed driving ring and is withstood on the said axle sleeve, and said uncompensated ring physical dimension is identical with the tailstock physical dimension of said sylphon seal head; The physical dimension that said axle sleeve, end cap are positioned at uncompensated ring part, tailstock part is also identical; The position of said uncompensated ring and said sylphon seal head can exchange, and when said sylphon seal head linked to each other with said end cap, said sylphon seal head was as rotating ring; Said uncompensated ring is as stationary ring; When said uncompensated ring linked to each other with said end cap, said uncompensated ring was as rotating ring, and said sylphon seal head is as stationary ring.
The tailstock of said uncompensated ring, sylphon seal head is positioned at axle sleeve or contacted of end cap goes up the corresponding groove that offers, and O type circle is installed in the said groove.
Characteristics of the present invention are: simple in structure; Be convenient to loading and unloading and replacing; The tailstock of uncompensated ring and sylphon seal head is designed to identical physical dimension, realizes the exchange of dynamic and static ring position, need not to design again end cap, axle sleeve; The purpose of the mutual conversion of rotary-type and static be can reach, time and material saved.
Description of drawings
Fig. 1 is embodiments of the invention one structural representations;
Fig. 2 is embodiments of the invention two structural representations.
Wherein: 1, axle 2, axle sleeve 3, O type circle 4, uncompensated ring 5, sylphon seal 6, end cap 7, tailstock 8, drive screw 9, driving ring.
Embodiment
Embodiment one
As shown in Figure 1; The present invention seals as the static welded metal bellow; Be sleeved on axle sleeve 2 outsides of axle on 1 uncompensated ring 4, sylphon seal 5, end cap 6, driving ring 9 are installed successively, said sylphon seal 5 is as rotating ring, and said uncompensated ring 4 is as stationary ring; On the said driving ring 9 drive screw 8 is installed; Said drive screw 8 is passed driving ring 9 and is withstood on the said axle sleeve 2, and tailstock 7 physical dimensions of said uncompensated ring 4 physical dimensions and said sylphon seal 5 are identical, and the physical dimension that said axle sleeve 2, end cap 6 are positioned at uncompensated ring 4 parts, tailstock 7 parts is also identical; Said uncompensated ring 4 and the said tailstock 7 corresponding grooves of placing O type circle 3 that offer; The said axle of driven by motor 1 rotation during work, said axle 1 passes to driving force on the said axle sleeve 2 through said drive screw 8, driving ring 9, and said uncompensated ring 4 is by the driving pin transmission rotation that is installed on the said axle sleeve 2; Said sylphon seal 5 is dialled by the stop pin that is installed on the end cap 6, prevents relatively rotating of said sylphon seal 5 and end cap 6; This structure is used for relatively poor relatively operating mode, and is higher like linear velocity, and viscosity is bigger, and pump shakes under the bigger situation.
Embodiment two
As shown in Figure 2; The present invention seals as rotary-type welded metal bellow, is about to uncompensated ring 4, sylphon seal 5 location swap among the embodiment one, and said sylphon seal 5 links to each other with axle sleeve 2 as stationary ring; Said uncompensated ring 4 links to each other with end cap 6 as rotating ring; The said axle of driven by motor 1 rotation during work, said axle 1 passes to driving force on the said axle sleeve 2 through said drive screw 8, driving ring 9, and said sylphon seal 5 is by the driving pin transmission rotation that is installed on the said axle sleeve 2; 4 of said uncompensated rings are dialled by the stop pin that is installed on the end cap 6, prevent relatively rotating of uncompensated ring 4 and end cap 6; This structure is used for general operating mode, requires linear velocity not high, and viscosity is little, and pump shakes under the smaller situation.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
