Abstract
Description
The present invention relates to a sealing structure of a screw connector, and more particularly, a sealing member having a predetermined width in the male thread section so as to catch and accumulate a sealing member (sealing tape) that is pushed outward when screwing the female thread and the male thread. It relates to a sealing structure of a screw connector forming an accumulation groove.
In general, fluids such as oil, gas, water including cold and hot water flow through pipes.
In this case, when a plurality of pipes are to be connected to each other, or when various valves for controlling the flow of fluid and the pipes are to be connected, in addition to when the sealing is required in connecting two objects to each other, a screw connector is used.
1 is a view showing an example of a conventional screw connector, the screw connector 1 is a female threaded
Therefore, when the
However, when the conventional screw connector 1 is screwed to the
In addition, since the
An object of the present invention for solving the above problems is to seal the accumulating member (sealing tape) to be pushed outwards when the female screw thread and the male thread screwed together to accumulate a certain width of the sealing member in the female thread or male thread section. By forming the accumulating groove, the accumulating portion of the sealing member accumulating on the sealing member accumulating groove is compressed on the mating thread side to improve the sealing property, and a screw thread is formed on the outer circumferential surface of the accumulating portion during the screwing process of the female and male threads. Since it is compressed on the mating thread side, the sealing property can be further improved, and since the sealing member is accumulated in the sealing member accumulating groove, it is not necessary to rewind the sealing member when separating and rejoining the female and male threads. It provides a sealing structure of screw connector that is convenient and reduces waste of sealing member. There is.
The present invention for achieving the above object, in the sealing structure of the screw connector comprising a female threaded connector formed with a female thread on the inner circumferential surface, and a male threaded connector is formed on the outer circumferential surface and screwed to the female thread, the female screw A certain width that is formed between the sealing member installed between the thread and the male thread and the female member or the male thread of the screw connector, and that catches and accumulates the sealing member that is pushed outwards when screwing the female thread and the male thread. And a sealing member accumulating groove, wherein the sealing member accumulates in the sealing member accumulating groove and is formed to seal between the female screw thread and the male screw thread.
The present invention provides a sealing member accumulating groove portion having a predetermined width in a female threaded or male threaded section of a screw connector so as to catch and accumulate a sealing member (sealing tape) that is pushed outward when screwing a female thread and a male thread. The accumulating portion of the sealing member accumulated in the member accumulating groove portion can be pressed against the mating thread side to improve the sealing property.
In addition, since the screw thread is formed on the outer circumferential surface of the accumulation part in the screwing process of the female screw thread and the male screw thread, the sealing property can be further improved.
In addition, since the sealing member is accumulated in the sealing member accumulating groove, the sealing member does not need to be rewound when the female thread and the male thread are separated and then recombined, thereby simplifying use and reducing waste of the sealing member.
In addition, by forming a sealing member accumulating groove portion in the screw thread of the female thread or male thread itself, the sealing tape accumulates in the sealing member accumulating groove, thereby effectively reducing the space generated when repeated expansion and contraction of the female screw connector and the male screw connector. Blocking improves sealing.
