食埋設用ボール弁。 A flange-type ball valve for buried city gas piping is a cap type that can be opened and closed at 90 degrees, and the connection between the cap and the main body is fitted with the stepped part of the main body,
Each fitting part has a neck flange or an appropriate length corresponding to both end flanges of a ball valve formed with a synthetic resin layer and capped with an O-ring attached to the synthetic resin layer to make it rotatable. The plastic lined steel pipe is welded to the companion flange, and then the two are connected via a gasket, or instead of the gasket, an insulating spacer is attached to one or both sides and the connection is assembled.
A ball valve for underground heavy corrosion protection for city gas, which is coated with a room-temperature processable thick-film paint that covers the entire outer circumference of the valve and a portion of the steel pipe, and the piping work is performed by welding the steel pipe section.
