KR20000004336U - Female threaded connector that can be used without leakage prevention material - Google Patents

Abstract

The present invention is designed for water leakage when interconnecting parts with external thread that are opposite to female thread (C / F) formed in flexible joints or pipe couplings (connectors) of all pipes used in hot and cold water piping facilities. Taking a taperon tape winding or a corresponding material is a quick and easy way to connect immediately without taking the corresponding design is a female threaded connector.

Description

Female threaded connector that can be used without leakage prevention material

In the construction of cold and hot water pipes, the pipes and pipes need connecting devices on the premise of airtightness and leakage prevention.

The main method is a screw connection method is widely used, and the screw connection method is a method of assembling by turning the mating male counterpart formed in the connector formed with the female thread.

In this case, in order to prevent leakage and leakage at the interconnected parts, the tape-on tape or the corresponding material should be wound or coated on the externally threaded parts and then assembled.

Therefore, there is a disadvantage that construction time delay and construction in a narrow place may cause erotic problems. The connectors should also be tightened beyond a certain force.

In order to eliminate the hassle of using the leakage preventing material generated during the connection of the conventional connector and to shorten the construction time, the connector is designed to prevent the leakage and leakage even if it is directly connected without using taperon tape or the leakage preventing material. .

4 is a state in which the leak is prevented by connecting the present object with a counterpart having an external thread

<Description of the code | symbol about the principal part of drawing>

1. Body of connector 2. Packing slot

3. Nut Nuts

5. Nuts 6. Nuts

7. Integral nut of inner nut and outer nut

8. External threaded parts

In order to achieve the above object, the present invention was assembled by inserting a packing in which the end of the counterpart having the external thread formed in close contact therebetween was separated by the body and the nut in the connector formed with the female thread.

If the packing is simply inserted into the connector where the female thread is formed on the body (without separating the body and nut), the packing should be inserted smaller than the minimum inner diameter of the screw surface. If the nut is assembled separately from the packing groove and the inner nut and outer nut are assembled, the packing size can be inserted larger than the outer diameter of the external threaded part. There is an advantage that it can last more stable.

When the final product of the present invention is fastened to the counterpart with the external thread formed, the external thread moves forward along the thread of the inner nut, and the inner nut rotates by interacting with the anti-convex protrusion and the anti-convex protrusion of the inner nut itself. This was prevented and fixed.

The external thread is moved forward and the packing surface is compressed so that the packing surface is compressed to prevent leakage and leakage.

Therefore, the present invention improves the speed of work and does not require the use of subsidiary materials (tapelon tape), and can maintain stable and longer air tightness than the method of inserting and tightening the packing without separating the body and the nut. In addition, by making the insertion groove of the packing, there is a greater effect to prevent the departure and loss of the packing.
