Valve with internal thread 1ase inch

Description

Ball check valves are used to prevent backward flow in the pipe. The flow is stopped by a ball, which is embedded in the valve body to create a seal. The ball valves are designed to allow a full throughout hole, thus avoiding the risk of blocking solid bodies. By turning in the flowing sewage, the ball has the ability to self -cleaning, and therefore the valve or leaks are rarely clogged. Ball check valves are recommended for sewage and rainwater pumping stations and to all media that can carry with them: sand, gravel, pieces of rags, cords, etc.

If the valve is blocked by abnormal sewage content, just unscrew the screws fastening the inspection cover, remove the ball and clean the contents of the valve. Such work should always be done with the pumping station power off. Before removing the inspection cover, check that it is closed over the ball check valve so that the returning sewage from the pipeline does not flood the tank and do not hinder the work of the conservator.

Location of the valve in the pumping station

The basic task of the valve is to prevent the return of pressed sewage, so we place it behind the pump on the discharge pump before shut -offs. Thanks to this solution, if you need to clean the valve or replacement, it is enough to pump sewage and close the latch. Working with the valve under these conditions will be much easier.

If the ball check valve is placed in a wet pumping station, where there is a risk of contact with sewage, it is best to place it above the medium level so that it is not flooded. If the valve has frequent contact with the medium due to the small dimensions of the tank, it is much safer to place it at the lowest sewage level so that it passes as little as possible through the sewage point - air. When there is no air access to air, corrosion processes will occur much longer than during continuous flooding and drying.

In the case of the work of two or more pumps in the tank, the ball check valves not only prevent the pumped liquid from reversing from the tank, but also the return of the liquid pressed by one of the pumps. In the absence of check valves, when one pump pumps it with the other discharge department, the sewage returns. This causes high losses of energy, time and very inefficient work of the pump syndrome.
