Abstract
The utility model relates to water sealing gasket. The water sealing gasket comprises a sealing gasket body; one side of the sealing gasket body is provided with a cylindrical bulge; the outer diameter of the cylindrical bulge is smaller than that of the sealing gasket body, and the inner diameter of the cylindrical bulge is smaller than that of the sealing gasket body; the other side of the sealing gasket body is provided with more than two protruded heads; the outer walls and the inner walls of all the protruded heads are positioned on the same circumferences respectively; and the diameter of the circle where the inner walls of all the protruded heads are positioned is greater than the inner diameter of the sealing gasket body.
Description
Technical field
The utility model belongs to field of sealing technology, is meant a kind of water-stop pad especially.
Background technique
Existing field of sealing technology, such as between the equipment of pipeline and so in order to guarantee sealing, selectable sealing means has multiple, using maximum is the water-stop pad.The existing gasket seal that uses all is pads of a circle type, and the advantage of this type pad is easy to process, but this type water-stop pad has following defective:
1, it is fixing that this pad can't keep between two joints, when assembling work, brings a lot of inconvenience for two joints to be connected, because of pad is deviate from from the joint easily.
2, this type of pad all is disposable, overhauls at every turn or must change pad again when safeguarding, otherwise just can not play seal action.
The model utility content
The purpose of the utility model provides a kind of novel seal pad, can repeatedly use also to keep the convenient fixing assembling work with joint to be sealed.
The utility model is realized through following technological scheme:
A kind of water-stop pad; Include the gasket seal body, in a side of gasket seal body one cylindrical convexity is arranged, the protruding external diameter of said cylindrical shape is less than the external diameter of gasket seal body; The internal diameter of cylindrical shape convexity is less than the internal diameter of gasket seal body; The opposite side of gasket seal body has independently prominent head more than two, and the outer wall of said each prominent head lays respectively on the identical circumference with inwall, and the diameter of a circle at the inwall place of said each prominent head is greater than the internal diameter of gasket seal body.
Protruding and the prominent head of said cylindrical shape is with connecting with circular arc between the gasket seal body.
A said independently prominent quantity is 3-6.
The diameter of a circle at said each prominent outer wall place is identical with the protruding external diameter of cylindrical shape.
The beneficial effect of the utility model is:
The head of when assembling, will dashing forward inserts and is arranged in the corresponding groove of a side in the joint pipeline, and the cylindrical shape convexity of opposite side matches with the opposite side circular groove of joint pipeline, has so promptly guaranteed the fixing sealing of also having played.

Embodiment
Below in conjunction with the concrete technological scheme of accompanying drawing detailed description the utility model, the specific embodiment of the utility model only is exemplary, can only be used to explain the utility model and can not be interpreted as to be the restriction to the utility model.
The utility model is realized through following technological scheme:
A kind of water-stop pad; The material of selecting for use is identical with existing pad, does not have ad hoc requirement, and the water-stop pad includes gasket seal body 1; Side at the gasket seal body has one cylindrical protruding 3; The external diameter of said cylindrical shape protruding 3 is less than the external diameter of gasket seal body, and the internal diameter of cylindrical shape protruding 3 is less than the internal diameter of gasket seal body 1, and said in the present embodiment cylindrical shape convexity is with connecting with circular arc between the gasket seal body; The cylindrical shape convexity is with being that at a certain angle mode connects between the gasket seal body in other embodiments; In order to reduce the resistance of liquid, preferably connect with circular arc, the protruding thickness of said cylindrical shape is the 1/3-1/2 of gasket seal body thickness.
The opposite side of gasket seal body has more than two independently prominent 2; The said in the present embodiment independently quantity of prominent head is 3-6; More preferably prominent quantity is four and is positioned at the some place that orthogonal two diameters intersect with the gasket seal body that the thickness of said prominent head is 1.5-2 times of gasket seal body thickness.The outer wall of said each prominent head lays respectively on the identical circumference with inwall, and the diameter of a circle at the inwall place of said each prominent head is greater than the internal diameter of gasket seal body, and prominent head is with connecting with circular arc between the gasket seal body.
In the present embodiment; The diameter of a circle at said each prominent outer wall place is identical with the protruding external diameter of cylindrical shape, and the diameter of a circle at said in other embodiments each prominent outer wall place can the enforcement that does not influence the patent art scheme inequality with the protruding external diameter of cylindrical shape.
The usage mode of patent art scheme is, in the joint pipeline to be sealed there is and the prominent corresponding groove of water-stop pad an end, and the size of this groove and the degree of depth adapt with prominent.The other end has a circle groove in the joint pipeline to be sealed, and the width of this groove and the degree of depth adapt with the cylindrical shape convexity, the water-stop pad is placed the back fastening in order promptly accomplish use.
The above only is the specific descriptions to the utility model technological scheme, and those skilled in the art can improve according to the present technique scheme certainly, and these improvement should be considered in the protection domain of the utility model.
Claims (6)
