Description
Technical field
The utility model relates to a kind of cable sealing device, and especially a kind of cable sealing device that can be used on axial-flow pump pit shaft, belongs to cable seal technical field.
Background technique
The axial-flow pump pit shaft of prior art in use, cable is directly through shaft wall, sealing material is filled with between cable and barrel, this cable seal structure using scope is limited, the cable being not only not suitable for different thicknesses uses, and when using in other position of pit shaft, need again to punch again packing matcrial.In addition, this cable seal is insecure, long-time use easily aging and leak.
Summary of the invention
The purpose of this utility model is to provide a kind of cable sealing device reliable and stable, easy to use.
The utility model adopts following technological scheme: a kind of cable sealing device, it comprises the framework sealing and be arranged on shaft wall, compressing member and sealing unit is filled with in described framework, described compressing member, sealing unit fits tightly together, described sealing unit is provided with seal modules, seal modules comprises and being set-located with one heart and the O-ring seal varied in size, in seal modules, adjacent two O-ring seals are tightly connected, described compressing member inside has the compressed part that two sectional dimensions reduce gradually, the small end of two compressed part is close, large end away from, large end and the described sealing unit of one of them compressed part are fitted, large end and the described frame seal of another compressed part are fitted, described compressing member has screwed hold-down bolt, the stud of hold-down bolt is between two compressed part and compress the small end of two compressed part.
In described framework, the quantity of sealing unit is two or more, and each sealing unit sealing paste is combined.
Spacing sheet is equipped with between described compressing member and sealing unit, between each sealing unit.
On a described sealing unit, the quantity of seal modules is two or more, and the size of seal modules has two or more.
In a described seal modules, the quantity of seal ring is more than three.
The beneficial effects of the utility model are: the utility model arranges framework on pit shaft, the hold-down bolt on compressing member is first tightened during use, the stud of hold-down bolt will jam-packed two compressed part, two compressed part are under pressure will deformed dilation, the compressed part adjacent with sealing unit will be adjacent to spacing sheet and sealing unit, thus makes to realize sealing between compressing member, spacing sheet, sealing unit.Can arrange multiple sealing unit in framework, can arrange multiple seal modules in each sealing unit, be inserted into by cable in suitable seal modules during use, seal ring coordinates with cable seal just can realize cable seal.The cable that the utility model is applicable to different thicknesses uses, but also can use in the plurality of positions of pit shaft, the seal modules good sealing effect that multiple seal ring forms, reliable and stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of embodiment of the utility model as depicted in figs. 1 and 2, the cable sealing device of the present embodiment comprises the framework 1 sealing and be arranged on shaft wall, compressing member 2 and sealing unit 3 is filled with in described framework 1, together with described compressing member 2 fits tightly with sealing unit 3, in described framework 1, the quantity of sealing unit 3 is two or more, each sealing unit 3 sealing paste is combined, between described compressing member 2 and sealing unit 3, be equipped with spacing sheet 7 between each sealing unit 3, spacing sheet 7 makes compressing member 2 and sealing unit 3 seal better.Described sealing unit 3 is provided with seal modules 4, and on a sealing unit 3, the quantity of seal modules 4 is two or more, and the size of seal modules 4 has two or more.Seal modules 4 comprises and being set-located with one heart and the O-ring seal varied in size, and in seal modules 4, adjacent two O-ring seals are tightly connected, and in a seal modules 4, the quantity of seal ring is more than three.Described compressing member 2 inside has the compressed part 5 that two sectional dimensions reduce gradually, close, the large end of small end of two compressed part 5 away from, the large end of one of them compressed part 5 and described spacing sheet, sealing unit 3 are fitted, the large end of another compressed part 5 and described framework 2 seal and fit, described compressing member 1 has screwed hold-down bolt 6, and the stud of hold-down bolt 6 is between two compressed part 5 and compress the small end of two compressed part 5.
The hold-down bolt on compressing member is first tightened when the present embodiment uses, the stud of hold-down bolt will jam-packed two compressed part, two compressed part are under pressure will dilatancy, the compressed part adjacent with sealing unit will be adjacent to spacing sheet, thus makes to realize sealing between compressing member, spacing sheet, sealing unit.Can arrange multiple sealing unit in framework, can arrange multiple seal modules in each sealing unit, be inserted into by cable in suitable seal modules during use, seal ring coordinates with cable seal just can realize cable seal.The cable that the utility model is applicable to different thicknesses uses, but also can use in the plurality of positions of pit shaft, the seal modules good sealing effect that multiple seal ring forms, reliable and stable.
Above-described embodiment is a kind of preferred embodiment of the utility model, and in other embodiment of the utility model, the spacing sheet between compressing member and sealing unit, between each sealing unit can be selected as required; In the number of sealing unit, single sealing unit, in the number of seal modules and single seal modules, the number of seal ring is all arrange flexibly according to actual needs; The seal modules of one or more different size can be had in single sealing unit.
What describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
