How to solve the leakage of fire trench pipe fittings

First of all, relieve the pressure to check the rubber ring, check whether the rubber ring is extruded and deformed, 1) if the rubber ring is wrong, replace the rubber ring directly, 2) if the riser rubber ring has been fixed and cannot be replaced, the rubber is padded inside the steel card shell to increase the compression.

Check whether the paint on the sealing surface of the pipe fitting has a large area falling off, 1) if it falls off, scrape the paint on the entire sealing surface;

2) Or replace the entire pipe fitting.

First of all, you see whether the tube is straight, whether there is any dislocation, whether the gasket inside is intact, whether the groove pipe fittings are quality problems, and it is very simple ,,,to change a pipe fitting first. I'm putting on a slap of pressure. Generally, the key leakage of the trench is easy to deal with.

Replace it directly! Very simple!

If it's not a critical part, it's cheaper to replace than to repair!

Summary. Yes, because the fire water is used for a long time, it will lead to damage and aging of the groove parts, resulting in water leakage.

If the fire water is used for a long time, will it cause water leakage in the groove parts?

Yes, because the fire water is used for a long time, it will lead to damage and aging of the groove parts, resulting in water leakage.

Just completed the project, Party A and the general contractor long-term fire water flushing sewer and floor washing, the original pressure pipeline, frequent mountain leakage.

First, an on-site inspection is carried out to find out the cause of the water leak. It may be caused by the aging of the pipeline, the interface is not round and tight, and the leakage point is caused by the opening belt. Based on the results of the inspection, appropriate measures are taken, such as replacing aging pipes at an early age, sealing joints, repairing leaks, etc.

I asked if it was caused by frequent use of fire water.

Yes, due to the frequent use of fire water, the water pressure will increase, resulting in water leakage. In addition, due to the high strength of the fire water, the disadvantage can cause damage to the pipeline, resulting in water leakage.

Groove parts sealing ring, long-term water discharge, and water replenishment, sealing ring, expansion and expansion, groove parts sealing ring should have elasticity, water resistance, coarse brightness, corrosion resistance, wear resistance and other characteristics, letter which should be regularly inspected and maintenance stool code protection, to ensure good sealing performance. In addition, seals that match the grooved pieces should be used to ensure the quality and performance of the seals.

1. Check the pressure of all, check whether the pipeline is coaxial, and replace the pipe fittings.

Fire trench pipe fittings are one of the many pipe fittings, if there is a water seepage problem in the process of use, the pressure should be relieved to check the rubber ring first, if the rubber ring is squeezed and deformed, the rubber ring should be replaced in time, and the rubber should be padded in the steel card shell to increase the compression.

In addition, because the paint will also cause water leakage, it is necessary to check the paint inside the sealing surface in time, and clean and replace the pipe fittings in time if it falls off.
