Abstract

A Polyvinyl Chloride Threaded Pipe Joint System With Coupler & Wire Locking device comprising two pipe joining components, two sealing rings, including a wire lock, the said wire lock is component being inserted into the groove which locks the coupling with the one end of the pipe joint, the said coupling joining the both the ends using the threads, the said threads are made in the form of square type threads and the said sealing rings are fixed to the both the ends of the pipes and coupler.

Claims

1. A wire lock system of threaded pipe and coupler made of polyvinyl chloride, comprising two pipe joining components, two sealing rings, including a wire lock, the said wire lock is inserted into the coupler groove and tangential hole which locks the coupling with the one end of the pipe. The said coupling system joins the ends of coupler and pipe using the threads, the said threads are made in the form of square type threads and the said sealing rings are fixed to coupler and joining pipe end before joining.

2. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the wire lock provided is inserted inside the coupler-tangential hole which also fits into the groove provided between the outer surface of the pipe and the inner surface of the coupler at the permanent pipe and coupler joint end.

3. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the wire lock inserted in the coupler-tangential hole is bent inside the space provided as milled groove in the joining coupler to fold within the outer diameter of joining coupler.

4. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the wire lock inserted in the coupler groove and tangential hole is in any shape of round, oval, square or sides flattened.

5. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the wire lock inserted in the coupler groove and tangential hole is made up of any metal, or rubber or plastics.

6. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the wire lock groove in the pipe is made to avoid any stress and damage to the joining coupler while tightening.

7. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the threads are tightened to the extent that there will not be any extra travel length for further fitment.

8. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the joining coupler is provided with two ribs on the outer surface to hold the pipe-wrench at the time of assembling and dismantling.

9. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the coupler inner sealing ring is provided at the coupler permanent end joint.

10. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the pipe outer sealing ring is provided to join with the coupler temporary end.

11. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the pipe outer sealing ring shape has the contact surfaces round or curved and the sides flattened.

12. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the front portion of the pipe to be fitted to the coupler permanent end, is machined to form a seat for coupler inner rubber ring.

13. A wire lock system of threaded pipe and coupler made of polyvinyl chloride according to claim 1, wherein the threads are in the form of square type having the gap on all sides between the threads, when coupler is completely threaded to pipe end.
