TECHNICAL FIELD

[0001] The utility model relates to half joint technical field, especially a half joint leak stoppage structure. BACKGROUND

[0002] Half joint is a pipeline leak stopper. Half joint and socket half joint are pipeline repair devices, the socket half joint is a device for repairing the leakage of the socket of two pipes, and the half joint is a device for repairing the part other than the socket. The device is simple in structure and consists of only two bodies and two rubber pads, and is easy to install. The repair of the pipeline can be completed by clamping the two bodies at the leakage position and tightening the nut. The device can save the time of stopping water supply and reduce the repair cost. The existing half joint is connected by half bolts. If the pipeline vibration is strong, the bolts are easy to loosen, which leads to poor sealing and secondary leakage. CONTENT OF THE UTILITY MODEL

[0003] The utility model discloses a half joint leak stoppage structure, through at least setting two rows of bolts on one side to carry out double protection, can improve sealing performance, reduce bolt loosening probability, through the spacing of the spacing of two half joints of half joint that the pulling of the limiting portion can guarantee, further guarantee sealing performance.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0005] A half joint leak stoppage structure, comprising two symmetrical half joints, a sealing element half is fixed on the inner wall of the half joint, wing plates are formed on both sides of the half joint, the wing plates on the same side of the two half joints are connected by at least two rows of bolts, and anaerobic glue is coated at the joint of the nut and the screw of the bolt.

[0006] Through setting two rows of bolts to carry out double protection, the probability of loosening due to vibration during use of the half joint can be reduced, and the loosening of the bolt can also be prevented by adding anaerobic glue to the bolt, so that the effective sealing of the half joint is ensured.

[0007] The utility model is further provided with the following setting: the two ends of the wing plate are higher than the half joint.

[0008] The end of the wing plate that is higher than the half joint is formed with a protruding portion extending radially inward, and the two oppositely arranged protruding portions are also connected by a bolt.

[0009] When the half joint clamps the pipe body, the force on the two ends of the half joint is relatively large compared to the middle part. By setting the protruding portion and the additional bolt, the clamping capacity of the end part can be further improved, the sealing performance of the end part can be further improved, and the loosening probability can be further reduced.

[0010] The present invention is further configured such that: a plurality of reinforcing ribs are provided between the wing plate and the half-section body.

[0011] Adding reinforcing ribs can prevent deformation when bolts are tightened on the flanges, thus increasing the stability of the connection between the two half-sections.

[0012] The present invention is further provided that: the reinforcing rib plate is formed with insertion holes;

[0013] The insertion holes of the two opposing reinforcing ribs are fitted onto the limiting part.

[0014] The limiting part is in the shape of a "U" rod.

[0015] The limiting part can pull the reinforcing ribs on the two flanges, thereby limiting the distance between the two flanges. Even if the bolts loosen later, the pulling of the limiting part can ensure the distance between the two half-sections, thus ensuring the sealing performance.

[0016] The present invention is further configured such that nuts are screwed to both ends of the limiting part, and the limiting part can be locked by the nuts to prevent it from falling off the reinforcing rib plate.

[0017] The outstanding effect of this utility model is:

[0018] Compared with existing technologies, double-layer protection by setting at least two rows of bolts on one side can improve sealing performance and reduce the probability of bolt loosening;

[0019] The spacing between the two half-sections can be maintained by the pulling of the limiting part, thereby further ensuring the sealing performance. Attached Figure Description
