Can a valve be installed in the sewer pipe of a building?

Valves can be installed on the sewer pipes of buildings.

Installing a check valve in the sewer can prevent the sewage from flowing backwards, and the check valve can block the medium from flowing backwards by its own weight and medium pressure. The movement mode of check valve disc is divided into lifting type and swing type. Special purpose valves include pigging valves, exhaust valves, sewage valves, exhaust valves, filters, etc.

The invention has the advantages of simple structure, good sealing performance, small volume, light weight, low material consumption and small installation size. Especially when the high-pressure boiler with pn≤2.0MPa is driven for periodic blowdown, five channels can blowdown at the same time, and one channel can blowdown.

Extended data:

The blowdown valve is an indispensable link in the sewage treatment system, which is mainly transformed from the gate. The gear can rotate 90 degrees to drive the valve stem to lift, so as to achieve the purpose of opening and closing.

Precautions for installing drain valve:

1. The installation of multi-way drain valve must be installed vertically on the horizontal pipeline.

2. Before installing the valve, the pipeline must be cleaned.
