Embodiment

[0013] like figure 1 , figure 2 The pipe joint shown has a neutron 5 with an inner diameter of 69 mm, a body 1 docked with the neutron, and an inner diameter of 69 mm. The neutron and the body are connected by a nut 4 sleeved on the outside of the body and the neutron. The connecting end of the cap 4 and the neutron 5 adopts an inverted L-shaped socket structure, and the connecting end of the nut 4 and the body 1 adopts an internal and external screw thread 8 connection structure; on the small diameter at the outermost end of the nut 4, it cooperates with the outer wall of the neutron There is a radial groove 41 on the surface (see image 3 As shown), in the radial groove, a nut ○-shaped sealing ring 6 that is sealingly matched with the outer wall of the neutron is arranged to make it play a sealing role between the nut and the neutron; Between the two end faces of the front end of the outer thread of the body, there is an annular metal gasket 3 made of aluminum. The inner ...

Abstract

The invention relates to a joint for a helix reinforced pipe. The joint is provided with a neutron and a body, wherein the body is in abutting joint with the neutron; the neutron and the body are connected through a screw cap which is sleeved outside the body and the neutron; a radial slot is arranged on a matching surface of the outer wall of the neutron on the outermost minor caliber of the screw cap; an O-shaped sealing ring of the screw cap hermetically matched with the outer wall of the neutron is arranged in the radial slot; in the screw cap, an annular metal gasket is positioned between the front end surface of the neutron and the front end surface of an outside thread of the body; an annular groove is arranged on one side surface of the annular metal gasket; an O-shaped sealing ring is arranged in the annular groove; and an annular rubber gasket is arranged between the annular metal gasket and the front end surface of the outside thread of the body. The joint for the helix reinforced pipe is hermetic and labor-saving, and can make the pipe arbitrarily rotate so as to achieve double effects. Development of the product greatly reduces labor intensity of an operator, and also improves working efficiency.

Description

technical field [0001] The invention relates to a pipe joint, in particular to an improvement of the structure of a rotary spiral reinforced pipe joint. Background technique [0002] The threaded spiral reinforced water suction pipe joint is connected and sealed by the body and the neutron through a nut, and the screw-in combination structure of an internal thread and an external thread is used between the nut and the body. In order to prevent water leakage, a rubber gasket is used inside the nut to stop water. When the internal and external threads are screwed in, the front end of the external thread on the body hits the rubber gasket, and then presses the rubber gasket to seal with the surface. In order to achieve the purpose of sealing, the joint must be tightened and screwed to the last place, it must be very hard. Therefore, in order to tighten the joint in the prior art, it is necessary to install a long handle on the nut or the body, or a special tightening tool is ...
