Abstract
The utility model discloses a vac-sorb sealing ring, which comprises a column-shaped mesopore, a contact sealing end surface and an outer surface encircling the column-shaped mesopore, wherein a vac-sorb groove is formed on the contact sealing end surface and/or the inner wall of the column-shaped mesopore. Owing to the vac-sorb function of the vac-sorb sealing ring provided by the utility model, the sealing between the sealing ring and a water inlet pipe can be improved, and the water seepage can be effectively prevented.
Description
Technical field
The utility model relates to a kind of seal member of flush toilet water inlet pipe, particularly a kind of vacuum suction RunddichtringO.
Background technology
As shown in Figure 1, the sealing ring outward appearance that is used for the flush toilet water inlet pipe is truncated cone-shaped, it has cylindricality mesopore and contact seal end face, in use requires to have good sealing effectiveness between flush toilet water inlet pipe and the sealing ring, to prevent that water stream is from leaking out between sealing ring and the water inlet pipe; In existing Sealing Technology, the contact seal end face of sealing ring and contact surface between the water inlet pipe only are to rely on closely contact (elastic deformation of rubber) and prevent that sealing medium from flowing and since the bounce that produces on the contact surface between sealing ring and the water inlet pipe when being installation external force make mutual extrusion generation between the two; Will cause installation not exclusively to put in place if external force is less when mounted, the pressure that produces on the contact surface between the two is less, to such an extent as to contact between the contact seal end face of sealing ring and the water inlet pipe dense inadequately, thereby cause between sealing ring and the water inlet pipe phenomenon that sealing medium flows taking place.In addition, also be to rely on closely contact to realize sealing between sealing ring mesopore inwall and the water inlet pipe, good sealing just can not be realized too greatly in the aperture of sealing ring mesopore, the too little difficult installation in aperture, and aperture and caliber all have the dimensions tolerance when producing, make and often can not realize good sealing between sealing ring mesopore inwall and the water inlet pipe.
The utility model content
At the deficiency that exists in the existing flush toilet water inlet pipe Sealing Technology, the purpose of this utility model is to provide good seal between a kind of and the water inlet pipe, prevents the vacuum suction RunddichtringO of infiltration phenomenon.
The technical solution of the utility model is achieved in that the vacuum suction RunddichtringO, described vacuum suction RunddichtringO has cylindricality mesopore, contact seal end face and around the external surface of described cylindricality mesopore, on the described contact seal end face and/or the inwall of described cylindricality mesopore be provided with the vacuum suction groove.
Above-mentioned vacuum suction RunddichtringO, described vacuum suction grooved ring is around the axis setting of described cylindricality mesopore.
Above-mentioned vacuum suction RunddichtringO, described contact seal end face is a convex surface, the high spot of described convex surface is provided with described vacuum suction groove.
Above-mentioned vacuum suction RunddichtringO, described external surface are the ogee concave surface, and this design helps the installing and locating of water inlet pipe, thereby more help sealing.
Above-mentioned vacuum suction RunddichtringO, described vacuum suction groove are that the cross section is semicircular groove.
Vacuum suction RunddichtringO beneficial effect of the present utility model is: one, owing to increased the vacuum suction groove, help when water inlet pipe is fastening, the air meeting emptying in the vacuum tank can make the utility model vacuum suction RunddichtringO be adsorbed on the water inlet pipe thereby produce vacuum state; Simultaneously, can improve the performance that deflects of the utility model vacuum suction RunddichtringO, help the dense property between the utility model vacuum suction RunddichtringO and the water inlet pipe; Its two, be the ogee concave surface around the external surface of described cylindricality mesopore, be to change traditional straight flange tapering into anti-arc tapering, the location when helping fastening the installation makes sealing effectiveness better; Its three, the vacuum suction groove of setting makes the volume of the utility model vacuum suction material that RunddichtringO uses reduce, and helps reducing cost; Its four because the utility model vacuum suction RunddichtringO architecture advances, can simplify the structure of water inlet pipe, reduce the parts of product, help saving cost.

Among the figure: 1-cylindricality mesopore, 2-contact seal end face, 3-vacuum suction groove, 4-external surface.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described further:
As shown in Figure 2, the vacuum suction RunddichtringO of present embodiment has cylindricality mesopore 1, contact seal end face 2 and around the external surface 4 of described cylindricality mesopore 1, described contact seal end face 2 is provided with vacuum suction groove 3; Described vacuum suction groove 3 is around the axis setting of described cylindricality mesopore 1, and described contact seal end face 2 is convex surface, and described vacuum suction groove 3 is arranged on the high spot of described convex surface; In addition, described external surface 4 is the ogee concave surface.Described vacuum suction groove 3 is that the cross section is semicircular groove, and this design helps the installing and locating of water inlet pipe, thereby more helps sealing, and with respect to the square-section, adopting the cross section is that semicircular groove makes the deformability of sealing ring and resilience better.
As shown in Figure 3, the vacuum suction RunddichtringO of present embodiment has cylindricality mesopore 1, contact seal end face 2 and around the external surface 4 of described cylindricality mesopore 1, is being provided with vacuum suction groove 3 on the described contact seal end face 2 and on the inwall of described cylindricality mesopore 1.Described vacuum suction groove 3 is around the axis setting of described cylindricality mesopore 1.Described contact seal end face 2 is a convex surface, and the high spot of described convex surface is provided with described vacuum suction groove 3.Described external surface 4 is the ogee concave surface.The vacuum suction RunddichtringO and the sealing effectiveness between the water inlet pipe of present embodiment are best, are the most preferred embodiment of the invention.
As shown in Figure 4, the vacuum suction RunddichtringO of present embodiment has cylindricality mesopore 1, contact seal end face 2 and around the external surface 4 of described cylindricality mesopore 1, described contact seal end face 2 is the plane.The inwall of described cylindricality mesopore 1 is provided with vacuum suction groove 3.Described vacuum suction groove 3 is around the axis setting of described cylindricality mesopore 1.Described external surface 4 is the ogee concave surface.
Vacuum suction RunddichtringO in the foregoing description has following three advantages: one, owing to increased described vacuum suction groove 3, help when water inlet pipe is fastening, air meeting emptying in the described vacuum suction groove 3 can make the utility model vacuum suction RunddichtringO adsorbed close on water inlet pipe thereby produce vacuum state; Simultaneously, can improve the performance that deflects of the utility model vacuum suction RunddichtringO, help the dense property between the utility model vacuum suction RunddichtringO and the water inlet pipe; Its two, be the ogee concave surface around the external surface 4 of described cylindricality mesopore, be to change traditional straight flange tapering into anti-arc tapering, the location when helping fastening the installation makes sealing effectiveness better; Its three, the described vacuum suction groove 3 of setting makes the utility model vacuum suction RunddichtringO use the volume of material to reduce, and helps reducing cost; Its four because the utility model vacuum suction RunddichtringO architecture advances, can simplify the structure of water inlet pipe, reduce the parts of product, help saving cost.
