Abstract
The utility model relates to a pipeline rubber sealing sleeve which is a cylindrical sleeve made of rubber. The pipeline rubber sealing sleeve is integrally formed by a sleeve body, connection rings and two installation holes, wherein the connection rings are symmetrically arranged on an upper end face and a lower end face of the sleeve body, and the two installation holes are coaxially and radially arranged in the middle of the sleeve body. The pipeline rubber sealing sleeve is characterized in that arc faces are symmetrically arranged on inner edge faces of the sleeve body, and a sealing line is respectively arranged on end faces of the two connection rings symmetrically and coaxially. The pipeline rubber sealing sleeve is simple in integral structure and scientific and reasonable in design, overcomes technical defects of existing valve sealing sleeves, prolongs service life of valves and improves sealing level of valves.
Description
Technical field
The utility model belongs to the rubber seal field, relates to rubber sealing boot, especially a kind of pipeline rubber sealing boot.
Background technique
On pipeline valve, need the pipe laying rubber sealing boot between the butterfly plate of butterfly valve or the flashboard of gate valve and the pipeline, be used to seal the gap between butterfly plate or the flashboard.At present, the inner edge of this stuffing box gland is a straight-tube shape, and the inner edge of stuffing box gland is that vertical plane contacts with the junction plane of butterfly plate or flashboard, when the vertical plane generation cut or the breakage of stuffing box gland just lost sealing, causes the inefficacy of valve.
In addition, the sealing between stuffing box gland and two duct also is end face seal, in case the distortion of stuffing box gland upper and lower end face takes place, also can make stuffing box gland lose sealing effect.
Therefore, there are above-mentioned two kinds of unsurmountable problems in existing stuffing box gland, need carry out technological improvement.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, the pipeline rubber sealing boot that provides a kind of end face and inner edge surface to have the compensation sealing function.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of pipeline rubber sealing boot; It is the cylindrical sleeve of making by rubber; Be made into integration by body, connecting ring and mounting hole; Upper and lower end at body is made connecting ring in the face of title, and mounting hole is two, and also coaxial radial system is at the body middle part, and it is characterized in that: the inner edge surface symmetry at body is shaped on arc surface.
And, all symmetrical coaxial potted line that is shaped on the end face of two connecting rings.
The advantage and the good effect of the utility model are:
1, this stuffing box gland is made the arc surface of symmetry on the inner edge surface of body, can realize the arc transition of inner edge surface and butterfly plate and flashboard thus, has improved sealing effect; Simultaneously, after the inner edge surface wearing and tearing or cut occurring, the external force of stuffing box gland outer edge surface can make inner edge surface jack-up, and the wearing and tearing of compensation inner edge surface continue to keep airtight quality, have greatly prolonged the working life of valve.
2, this stuffing box gland in the upper and lower end face of body connecting ring all coaxial potted line that is shaped on, can improve sealing effect and wear compensation equally.
3, this stuffing box gland overall structure is simple, and design science is reasonable, has overcome the technological deficiency that existing valve seal cover exists, and has prolonged the working life of valve, has improved the sealing level of valve.
Description of drawings
Fig. 1 is the structural front view of the utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing, through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of pipeline rubber sealing boot is the cylindrical sleeve of being made by rubber, is made into integration by body 3, connecting ring 1 and mounting hole 4, and in the face of claiming to make connecting ring, mounting hole is that two and coaxial radial system are at the body middle part at the upper and lower end of body.
The innovative point of the utility model is:
1, on the end face of two connecting rings, all be shaped on potted line 2 with axisymmetric, potted line is one in the present embodiment accompanying drawing, also can be set at coaxial many; The width and the diameter of potted line are set according to actual needs.
2, the inner edge surface symmetry at body is shaped on arc surface 5, to realize that butterfly plate and flashboard are arc transition with contacting of inner edge surface.The radian size of arc surface is set according to technical requirements, for harder rubber material, can suitably improve radian.
