Abstract

DC60 (10/08/54) invention. To provide a means of push-fitting for connecting pipes through socket joints that do not Only flexible tubes (like PEX pipes) are inserted. But it also ensures a good sealing. Of the coupling socket and the connection holder when the hose is injected with fluid and pressurized to expand where it is made up of a coupling socket where in the direction of the inlet pipe, which forms a ring Catch, stop ring and o-ring respectively where when the tube enters the said fitting The wings are arranged on the ring. Such a catch will then be refracted. When the tube is injected with liquid and pressurized to expand it, the O-ring is pressed and axially expanded, then the O-ring pushes the stop ring to push the holding ring. Said to move in the reverse direction of the inlet pipe. The pipe was then locked. The invention also provided a pressure fitting socket, using the same method for supplying liquids. This invention To provide a means of push-fitting for connecting pipes through inlet connectors that do not Only flexible tubes (like PEX pipes) are inserted. But it also ensures a good sealing. Of the coupling socket and the connection holder when the hose is injected with liquid and is pressurized to expand where it consists of a coupling socket where in the direction of the inlet pipe, which creates: The retaining ring, retaining ring and o-ring, respectively, when the pipe enters the said coupling The wings are arranged on the ring. Such a handle will then be refracted. When the tube is injected with liquid and pressurized to expand it, the O-ring is compressed and extended along the axan basis, then the O-ring pushes the stop ring to push it. Moving in the reverse direction of the pipe inlet The hose was then locked, the invention was also provided to the pressure fitting, using the same method for supplying fluid:

Claims (9)

1. The pressure-on method for connecting pipes through the socket joints is characterized by that The coupling socket consists of a coupling socket (1) where in the direction of the inlet pipe, formed: holding ring (4), stop ring (3) and O-ring (2) respectively, where when The tube (13) enters the connector, the wing edge (12) arranged on the said ring (4) is refracted. When the tube was injected with liquid and pressed Pressure to expand The O-rings (2) are pressed and enlarged axially. The O-ring (2) then pushes the stop ring (3) to push the holding ring (4) in the reverse direction of the inlet pipe so that the pipe (13) can be locked. 2. The coupling socket used to be pushed using the method in item 1 is characterized by the following characteristics: the socket body (1) where in the direction of the inlet pipe, which is formed: the cover (5) For the protection of various assemblies In the socket, such joints do not come off. The stopping part of the cover (9) arranged at the end of the said socket through which the pipe (13) enters to prevent the cover (5) from coming off; Removable ring (6) for unlocking the said tube (13); A handle ring (4) consisting of a wing edge (12) and a number of teeth (10) arranged on Flange for holding onto the outer wall of the pipe (13); Stop ring (3) (in movable connection with the inner wall of the socket body (1)) for stopping the holding ring (4) from moving in the direction of the pipe inlet. The shoulder used to stop the retaining ring (8) is arranged on the inner wall of the socket body (1) for stopping the retaining ring (3) from moving in the direction of the pipe inlet; The arrangement of the shoulders used Stop the aforementioned ring (8) and such a cap (5), causing independent axial movement of the The aforementioned grab ring (4) and the aforementioned ring (3) between them; O-ring (2) for creating a sealed connection to the outer wall of such pipe (13); The shoulder used to stop the O-ring (7) (arranged on the inner wall of the casing into the said fitting (1)) to stop the O-ring (2) from moving in the direction of the track. Into the pipe; The shoulder used to stop the pipe (11) (arranged on the inner wall of the said socket body (1)) to stop the pipe (13) from moving in the direction of the respective inlet; Where when the pipe (13) enters the said fitting socket The wing edge (12) of the aforementioned ring (4) was refracted; When the fluid is directed into the tube and the tube is pressurized. The O-rings (2) are pressed and enlarged axially. The O-ring is then pushed (2) the retaining ring (3) to prevent the holding ring (4) move in the reverse direction of the pipe inlet. Therefore, the said pipe (13) can be locked. 3. The coupling socket in item 2 is characterized by the presence of an O-ring (14) arranged between the shoulder used to stop the O-ring (7) and the shoulder to stop the ring. (8), layers (15) in a movable sealed connection with the said O-ring position (14) are arranged at The end of the shoulder used to stop the O-ring (7), adjacent to the O-ring (2), where the layer (15) is maintained with a sealed connection that can move steadily. With the O-ring position (14), when the stop ring is pushed to move in the reverse direction of the inlet pipe. 4. The socket joints in clause 2 or 3 were made with the characteristics that The gap between the shoulder used to stop the O-ring (7) and the cover (5) causes the O-ring (2) to push the handle ring (4) against the cover (5) through the stop ring. (3) when the duct is also injected Liquid and pressurized to expand, press the O-ring (2) until it expands axially. 5. The socket joints in Article 4 were made with the characteristics that The gap between the shoulder used to stop the O-ring (7) and the said stop ring (3) is not narrower than the Width along the scan line of the O-ring (2), which is compressed when the tube (13) passes through the O-ring (2). 6. The socket of the joints in clause 5 was made with the characteristics that The inner diameter of the teeth (10) at the beginning of them was smaller than the line. Through the outer center of the said tube (13) the internal diameter of the said O-ring (2) is smaller than the outer diameter of the said tube (13) and the inner diameter of the said ring (6) is larger than the Such pipe (13) 7. The socket connector in Article 6 is characterized by that The stop ring (3) is a ring and has a slope that works with it (10). 8. The socket-outlet in Clause 7 has been characterized in addition to the assembly. The shoulder stop cover (17) is arranged on the inner wall of the socket body (1)) between the said ring (4) and the cover (5) to prevent stopping. Such a cap (5) does not move in the direction of the inlet pipe. The protrusion (16) is arranged on the outer wall of the removable ring for use. To the cover (5) in order to avoid the removal ring (6) from falling out of the fitting. 9. The socket connector in Article 8 is characterized by that The removal ring (6) has an acute angle at the end of the removal ring (6) attached to it (4).
