Description
Technical field
The utility model relates to a kind of assembling pipe joint, relates in particular to a kind of quiet jointing of leaking of preventing.
Background technique
The device that existing pipeline connects adopts joint to connect, also have the three-way pipe of employing, the directly connections such as pipe, bend pipe usually in some plastics hot-water heating pipes.Being connected of joint and plastics hot-water heating straight length adopt sweat soldering to connect or the locking by lock nut connects, above-mentioned two kinds of Placement sweat solderings connect owing to need to adopt the power consumption parts such as heat melting device to connect, and the connection procedure complexity is loaded down with trivial details.Adopt the locking of lock nut to connect, owing to be to utilize the mode of the built-in snap ring chucking straight length of lock nut to reach the technical purpose that is fastenedly connected, cause the joint joint to leak along with long-time use lock nut is often loosening easily.
For example disclose a kind of rapid pipe joint of die cooling pipeline in the Chinese utility model patent 200420102227.9, consisted of by body, seal ring, ring-like pressing plate and tightening nut; The shaft section of body is approximate T-shape, one section Cooling Holes that is positioned at mould of the convex shoulder of body and close convex shoulder, and seal ring is positioned at the Cooling Holes of mould and is enclosed within the periphery of the body of Cooling Holes; The remaining part of body is positioned at outside the Cooling Holes of mould; Ring-like pressing plate is between seal ring and tightening nut and be fixed in the cooling port of mould, stops seal ring displacement.The technical clarification that how to prevent that lock nut is loosening and improve sealability is not mentioned in this kind rapid pipe joint.
Summary of the invention
The utility model provides a kind of simple in structure, easy for installation, good seal performance, connection the fastening quiet jointing that leaks of preventing.
A kind of quiet jointing of leaking of preventing, comprise the tubular configured joint body that connects straight length, the external diameter of joint body internal diameter and straight length is connected, the joint body end is provided with the outside thread lock nut that is connected, outside thread inboard, described joint body end is provided with the hole enlargement hole, bottom, hole enlargement hole is equipped with, and the seal ring of socket straight length is provided with the locking device of locking straight length between seal ring and the lock nut; Described locking device cooperates the outer ring of hole enlargement hole internal diameter and an internal diameter to cooperate the inner ring of straight length external diameter to consist of by an external diameter, and outer ring and inner ring are intermeshing, and Surface of action is cone structure.The ring structure of bottom, hole enlargement hole socket straight length is located in this kind employing, reaches the technique effect of airtight connection in the locking straight length in conjunction with the locking device that is made of with inner ring intermeshing outer ring.Certain inner ring is enclosed within the straight length periphery.The locking device of the locking straight length that arranges between above-mentioned seal ring and the lock nut, in lock nut spiral locking process, locking device is owing to be subject to the lock nut end thrust, utilize the outer ring of locking device and the cone structure of inner ring Surface of action, reach the locking purpose so that inner ring is constantly locked straight length.Seal ring also is subject to thrust in the lock nut spiral locking process, causes that thus the seal ring radial deformation further improves the sealing effect that contacts with the straight length outer wall.
Described inner ring circumference is provided with axial fracture, reaches the technical purpose of holding straight length tightly so that inner ring diameter can be out of shape to dwindle.Described inner ring inside circumference is provided with annular flange flange and further locks straight length.
After assembling mutually, the outer ring of described locking device and inner ring be the pipe segment structure, pipe section one end in contact seal ring, the other end contact lock nut; Described pipe section contact lock nut one end, lock nut not under the locking state this termination stretch out hole enlargement outer end of hole face, this termination contact hole enlargement outer end of hole face under the lock nut locking state.This kind locking mounting type is because pipe segment structure and the seal ring of locking device all are subject to larger axial force, seal ring is known elastic material manufacturing after the locking, utilize distortion reposition force and the pipe section elastic deformation force of seal ring, prevent that lock nut is loosening so that be subject to axial force between the thread engagement between lock nut and the joint body end outside thread.
Described joint body is bend pipe structure, and end, bend pipe two ends is equipped with the lock nut that outside thread is connected; Outside thread inboard, end, bend pipe two ends is equipped with the hole enlargement hole, and bottom, hole enlargement hole all is equipped with seal ring, is equipped with the locking device of locking straight length between seal ring and the lock nut, two straight lengths of convenient connection.
The utility model adopts is located at bottom, hole enlargement hole, is socketed the ring structure of straight length, reaches the technique effect of airtight connection in the locking straight length in conjunction with the locking device that is made of with inner ring intermeshing outer ring.
Description of drawings
Fig. 1 is that the utility model prevents the quiet jointing sectional structure schematic representation that leaks.
