Definitions

  • the present invention relates to screw-type fittings used when pipes are connected with each other.
  • pipes such as water supply pipes, drain pipes, gas pipes, and oil pipes, are installed.
  • One-touch type fittings are generally used when pipes of a small diameter such as air hoses are connected with each other, but screw-type fittings or socket type saddles are widely used when pipes of a large diameter are connected with each other.
  • a pipe fitting is connected to a pipe by a screwing method, a cap, a pusher and an 0-ring are pushed into a place of a pipe fitting body, which is twice as large as the diameter of the pipe, in order.
  • An end of the pipe is pushed to the center of the pipe fitting body so as to closely contact the Q-ring and the pusher to the body to the maximum, and then, the cap and the body are coupled with each 'other by a chain wrench.
  • the conventional fitting has another problem in that water leakage is caused when the cap is loosened just a little. [11] Therefore, the conventional screw- type fitting method is very inconvenient, complicated and difficult, and requires much time.
  • an object of the present invention to provide an improved screw-type fittings, which includes a tiered pipe fixing jaw, a packing for preventing water leakage, and a projection formed between the pipe fixing jaw and a body, thereby bein g coupled with a pipe in safe, preventing water leakage even though a cap and the body are coupled with small power, and allowing a user to rapidly finishing fitting work by firmly tightening the pipe with a few processes.
  • the conventional screw-type fittings deteriorates work efficiency and economical effect since they are complicated in configuration and difficult in installation, and requires much time to install.
  • the screw-type fittings according to the present invention provides an economical effect and allows the user to easily conduct fitting work with small power, since it is simple in configuration, allows the user to easily conduct fitting work, and completely prevent water leakage.

  • a pipe fitting (A) includes a body 40, a leakage preventing packing 30 inserted into the body 40, a holder 20 inserted into the body 40 next to the packing 30 in order to directly tighten a pipe (P) and a cap 10 coupled with the body 40 for compressing the holder 20 to the pipe (P).
  • the body 40 includes a packing insertion slot 43 for inserting a wing part of the packing 30 thereinto which is in a close contact with the inner periphery of the body 40 by pressure when the packing 30 is inserted into the body 40.
  • the inside of the body 40 is processed in such a way as to have the same angle as the outer diameter of the packing 30 so that the packing 30 is in more close contact with the inner periphery of the body 40.
  • the holder 20 which has a saw-toothed inner periphery, is inserted into the body 40 for preventing separation of the pipe (P) and fixing the pipe (P) to the pipe fitting.
  • the body 40 has a projection 41 formed on the inner periphery thereof and the holder 20 has a projection 21 formed on the outer periphery thereof for easy connection and separation between the body 40 and the holder 20.
  • a user oouples the cap 10 with the body 40 a little, and then, completely couples the cap 10 with the body 40 after pushing the pipe (P) into the body 40.
  • the body 40 includes a tiered pipe fixing jaw 42 formed on the inner periphery thereof in order to preventing movement of the pipe (P) inserted into the body 40, so that an end section of the pipe is in close contact with the tiered pipe fixing jaw 42 and prevented from movement.
  • the holder 20 is divided into four sections in such a way that the holder 20 is compressed or released according to, whether or not the cap 10 is coupled wiuVthe body 40.
  • an inclination angle (Cl) of the holder 20 is smaller than an inclination angle (C2) of the cap 10, whereby the holder 20 can be more strongly compressed with smaller power.
  • the present invention allows anybody to easily and simply connect and separate the pipe to and from the pipe fitting by releasing the cap 10 a little in a state where the packing 30 and the holder 20 are always coupled with each other inside the body 40.

Abstract

La présente invention concerne un raccord fileté pour raccordement de conduites. Le raccord fileté de cette invention comprend: un corps (40); une garniture de prévention de fuite (30) insérée dans le corps (40); un support (20) inséré dans le corps (40), et ce support (20), qui comporte une périphérie interne dentelée (22), est divisé en une pluralité de zones pour empêcher qu'une conduite (P) ne se sépare du raccord de conduite (A); et un capuchon (10) couplé au corps (40) de façon à comprimer le support (20) contre la conduite (P) afin de fixer la conduite (P). Le corps (40) comprend une fente (43) d'insertion de garniture servant à prévenir plus efficacement les fuites d'eau et une mâchoire de fixation de conduite à paliers (42) servant à empêcher la conduite de bouger.
