Description

Non water blockage valve chamber that is easy to construct on the existing pipeline}

The present invention relates to a non-stage valve room that is easy to install on a duct of an existing piping so that a non-stage valve room can be easily installed in an existing piping without cutting or disconnecting the previously installed pipe.

In general, the water supply valve room is buried in the ground, and various valves such as air valves, water control valves, pressure reducing valves, flow meters, etc. that perform various functions are installed in the water supply pipe.It is a space for maintenance and inspection of the water supply pipe. Is being used.

These water supply valve chambers can be largely divided into iron-type water supply valve chambers and concrete-type water supply valve chambers. However, the concrete type occupies a large proportion of the water supply valve room currently buried in Korea.

However, since the concrete type water supply valve room has poor waterproofing performance, condensation occurs inside the water supply valve room, or external moisture flows into the water supply valve room and corrosion occurs in piping, various valves, and flow meters in the water supply valve room, which shortens the lifespan. There is a problem.

Therefore, in order to solve the problem of such a concrete type water supply valve room, a lot of work has been made to replace the concrete type water supply valve room with an iron type water supply valve room.

However, when the existing concrete type water supply valve room is replaced with a steel type water supply valve room, or when equipment such as valves, pressure gauges, flow meters, etc. are installed in the existing pipe, the existing water supply pipe must be cut, resulting in water outages in the relevant area. It is done. There is a problem that when the water outage occurs, the number of civil complaints from residents increases.

Therefore, it is mainly implemented as a welding type due to watertightness problem and construction efficiency problem, but this causes secondary problems such as paint damage and structural deformation due to welding heat, and to replace the concrete type water supply valve room with the steel type water supply valve room. In the case of cutting the water pipe of the water supply pipe, the possibility of leakage increases as the junction of the water supply pipe increases, and the construction cost increases, and there is also a problem that the construction cost increases when using many equipment such as generators, welding machines, and cutting machines. .
