Maintenance skills of fire hose clamp joint leakage
Detailed explanation of maintenance technology for fire hose clamp joint leakage:Trench type fire pipeline after used for a long time, if all of a sudden pressure relief after prone to the displacement of the pipeline caused by clamp joint Water Leakage, by tightening the clamp bolts do not necessarily have a good effect, because of aging, lack of elastic rubber ring.
The best approach is to remove the clamp groove on the inner wall of the groove, cut a layer of 3mm thick rubber (or thin rubber inner tube), the inner wall of the groove width is smaller than the width of about 2~3mm, their good after the clamp bolt is good, no Water Leakage the problem.
A fuse is generally used when Water Leakage threaded connection, trench connection pipe to check whether the sealing surface is flat and smooth, without burr. Whether the sealing surface of the sealing ring is scratched and whether the length of the sealing section meets the requirement. These are three guarantees. They won't leak.
