Ring-shaped groove arranged on described main part one end, the main part is arranged in porthole, and one end of pipeline is arranged in
In the ring-shaped groove；And
It is connected to the main part other end and the annular seal set around the main part, the annular seal
In cap shape, the annular seal is attached on the metope of the porthole side.
Preferably, the annular seal includes the coupling part being connected with the main part and by the coupling part
The skirt portion extended to form is bent, the skirt portion is in shirt rim shape.
Preferably, the skirt portion surrounds annular groove with the coupling part.
Preferably, the annular seal is integrally formed with the main part.
Preferably, the shore hardness of the porthole seal is 65-75A.
Preferably, the porthole seal by ethylene propylene diene rubber, silicon rubber, fluorubber or polyurethane into.
Compared with correlation technique, porthole seal provided by the utility model by setting main part, arranged on the main body
The ring-shaped groove of portion one end and be connected to the main part other end and in cap shape annular seal, by described in setting
Ring-shaped groove, it is only necessary to which ring-shaped groove is sleeved on pipeline one end, it is not necessary to which other fixing pieces connect, and make the porthole seal
It is easy for installation.By the way that annular seal is arranged to cap shape, annular seal is stayed in advance with metope at regular intervals, squeezing
When pressing the annular seal, which can adapt to metope automatically according to the flatness of metope, and the annular seal is not
Each position on smooth metope has different compression, so that the annular seal can be bonded completely with metope, avoids
There are larger gap between metope and seal, so that the porthole seal sealing effect is good.

Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
Fig. 1-Fig. 3 is refer to, wherein, Fig. 1 is the stereogram of the utility model porthole seal；Fig. 2 is the utility model
The stereogram at another visual angle of porthole seal；Fig. 3 is the structure diagram of the utility model porthole seal.The porthole is close
Sealing includes the main part 1, the ring-shaped groove 2 arranged on described 1 one end of main part and connection for being cylindrical in shape structure and both ends perforation
In the annular seal 3 of 1 other end of main part.
The main part 1 is contained in porthole completely, and the ring-shaped groove 2 is arranged on described 1 one end of main part, the main body
Portion 2 is arranged in porthole, and one end of pipeline is arranged in the ring-shaped groove 2.When sealing porthole, pipeline is located in porthole
One end be plugged in the ring-shaped groove 2, to realize the docking of porthole seal and pipeline.Wherein, the ring-shaped groove 2
The diameter of diameter and pipeline is corresponding, and the width of the ring-shaped groove 2 is corresponding with the wall thickness of pipeline, makes the ring-shaped groove 2
Good fixation is played with pipeline.By setting the ring-shaped groove 2, it is only necessary to which ring-shaped groove 2 is sleeved on pipeline one end
, it is not necessary to other fixing pieces connect, and make the porthole seal easy for installation.
The annular seal 3 is connected to 1 other end of main part and is set around the main part 1, the porthole
Seal is in integrally bacterium shape, wherein, the annular seal 3 is in cap shape, and the annular seal 3 is arranged to fexible film
Shape.The annular seal 3 is attached on the metope of porthole side, and when sealing the pipeline in porthole, one end of pipeline is inserted
