[0002] At the end of the installation of the pvc pipe, the tail end should be blocked and sealed. The existing sealing of the pvc pipe is only through the plugging block to block the head, but in the long-term use process, the liquid transmitted in the pvc pipe will seal the block The impact makes the seal between the two loose, and liquid leakage is prone to occur. For this reason, we design a head structure for the tail of the pvc pipe

The invention discloses a seal structure for a PVC pipe tail. An annular clamping groove and a sealing groove are formed in the pipe wall of the tail end of a PVC pipe; the clamping groove is arrangedon the outer side of the sealing groove; a clamping ring and a plug block, forming an integral structure, are arranged on one side surface of a sealing cover; the clamping ring is arranged on the outer side of the plug block; a sealing ring is embedded in the sealing groove at the tail end of the PVC pipe; the clamping ring on the side surface of the sealing cover is tightly clamped into the clamping groove at the tail end of the PVC pipe; the plug block on the side surface of the sealing cover is inserted in the pipe; a connecting sleeve sleeves the outer side of the tail end of the PVC pipe; multiple ejecting bolts are inserted in the connecting sleeve; the tail ends of the multiple ejecting bolts are butted and locked with the outer wall of the PVC pipe; and the connecting sleeve and the sealing cover are fastened, locked and connected through locking nuts tightly screwed at two side rod ends of a stud. The seal structure is simple in structure, convenient to assemble, connect andinstall and reliable in sealing between the sealing cover and the PVC pipe.
Description
technical field [0001] The invention relates to a head structure for the tail of a PVC pipe, which is applied to the technical field of PVC pipe installation. Background technique [0002] At the end of the installation of the pvc pipe, the tail end should be blocked and sealed. The existing sealing of the pvc pipe is only through the plugging block to block the head, but in the long-term use process, the liquid transmitted in the pvc pipe will seal the block The impact makes the seal between the two loose, and liquid leakage is prone to occur. For this reason, we design a head structure for the tail of the pvc pipe. Contents of the invention [0003] In order to solve the defects of the prior art solutions, the invention discloses a head structure for the tail of a PVC pipe. [0004] The invention discloses a head structure for the tail of a pvc pipe, comprising: a pvc pipe, a cover, a plug block, a connecting sleeve, a double-ended screw, a lock nut, a jacking bolt, and...
