Since this is an open matter, no full text was included.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a longitudinal sectional view showing an embodiment of a pipe joint according to the present invention, in a state in which a valve body closes a flow path. 2 is a longitudinal sectional view of a copper pipe joint showing a state in which a valve body is moved by a tube and a flow path is developed. 3 is a perspective view of a valve body used for a copper pipe joint.

Claims (10)

Inside the joint body, a valve body movable in the major axis direction of the joint body and biased from the primary side to the secondary side, and a ring-shaped seal member in contact with the valve body to close the flow path in the joint body. And a valve joint configured to move the valve body in contact with the seal member to open the flow path by a tub connected to the secondary side of the joint body, wherein the valve body is provided on an inner wall surface of the joint body. A fixing ring for restricting movement to the secondary side of the fixing ring, and the sealing member is disposed on the secondary side of the fixing ring, and the valve body is connected to the sealing member through the center hole of the fixing ring. The tubular to be inserted and connected is inserted into the center hole of the sealing member from the secondary side and sealed. moo. The pipe joint according to claim 1, wherein an inner surface of the center hole of the seal member is in the shape of a side surface of a substantially cone having a diameter increasing from the primary side to the secondary side. The pipe joint according to claim 2, wherein the seal member has a ring-shaped lip at its inner edge and is sealed by the lip. The pipe joint according to claim 3, wherein the seal portion of the valve body is in the shape of a truncated cone whose diameter decreases from almost primary to secondary. The pipe joint according to claim 1, wherein said fixing ring has one of its opposite faces facing each other at the cutout, while the other is facing outward with respect to the radius. 2. The support of claim 1, wherein a plurality of support protrusions are disposed at the secondary end of the valve body at intervals in the circumferential direction, and these support protrusions abut the tip of the tub connected to the secondary side of the joint body. Pipe joints intended to be used. The pipe joint according to claim 4, wherein the secondary end portion of the seal portion of the valve body is rounded in an arc shape. An anchoring ring for a pipe joint, which is placed in a concave locking groove formed in the joint body, wherein one end face is inward of a radius through the inner edge of two end faces facing each other in the cutout. And a cross section on the other side facing outward with respect to a radius passing through the inner end thereof, and a distance between both end faces increases from the inner diameter side toward the outer diameter side. The holding ring according to claim 8, wherein a cross section of the two cross sections facing inward with respect to a radius passing through the inner edge forms an angle of 30 ° to 60 ° with respect to the radius thereof. The fixing ring according to claim 8, wherein an angle formed by the two cross sections is larger than an angle formed by the cross section facing inward with respect to a radius through the inner edge. ※ Note: The disclosure is based on the initial application.
