Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the invention, and is not intended to exhaust all possible ways of practicing the invention, nor is it intended to limit the scope of protection of the invention.
A detailed description of an embodiment of the tubular filler neck according to the invention is given below with reference to fig. 1 to 3.
In the present embodiment, as shown in fig. 1 and 2, the tubular filler neck according to the present invention includes a tubular wall portion 1 and an elastic sealing body 2.
In the present embodiment, as shown in fig. 1, 2, and 3, a filling hole 11 is formed in the tubular wall portion 1 in the axial direction thereof, and a recessed groove portion 12 is formed in the tubular wall portion 1. Wherein, the filling hole 11 is the circular port, and the cross section of the outer wall surface of tubulose wall part 1 is circular, and concave part 12 is annular shape, and the cross section of concave part 12 can be the V-arrangement, and the aperture of the round hole that concave part 12 formed is less than the aperture of filling hole 11.
The groove portions 12 are two, and the two groove portions 12 are provided at intervals in the axial direction of the tubular wall portion 1.
In the present embodiment, the recessed portion 12 may be formed in the tubular wall portion 1 by spinning.
In the present embodiment, as shown in fig. 1 and 2, the elastic sealing body 2 is provided in the filling hole 11 to seal the filling hole 11.
In the present embodiment, the two recessed portions 12 press the elastic sealing body 2, and further, the elastic sealing body 2 can be prevented from moving in the axial direction of the tubular wall portion 1.
In this embodiment, an injection mechanism (e.g., a filling needle) can penetrate the elastic sealing body 2 to fill the interior (i.e., the left portion in fig. 2) of the tubular device with the working medium, and after the injection mechanism is withdrawn, the elastic sealing body 2 automatically tightens and seals the filling hole 11, thereby preventing the working medium from leaking.
In the present embodiment, the elastic sealing body 2 may be an elastic gel (e.g., a silicone gel).
In the present embodiment, the cross section of the elastic sealing body 2 may be polygonal, circular, or other irregular shapes.
In the present embodiment, the elastic sealing body 2 has a certain heat resistance. Thus, when the filling of the working medium is completed and the filler opening is sealed by welding (secondary sealing), the elastic sealing body 2 can withstand the high temperature generated during the operation.
The method for manufacturing the tubular filler port of the present invention will be briefly described below.
First, a port of the tubular device is preliminarily shrunk, so that the aperture of the port is slightly larger than the outer diameter of the elastic sealing body 2 (the elastic sealing body 2 may be cylindrical).
