Title:
SHUTOFF VALVE UNIT
Document Type and Number:
WIPO Patent Application WO/2010/143382
Kind Code:
A1
Abstract:
Provided is a shutoff valve unit whose housing is easy to attach to a press-worked metal plate gas meter, and which is resistant to foreign matters or water in the pipe line, misbehavior and inexpensive. The shutoff valve unit includes an inlet tube (51), a reducing chamber (52) disposed below and having a cross section larger than that of the inlet tube (51), a side passage (53) provided on a side and at a location higher than the bottom (52a) thereof in the horizontal direction, and a valve chamber (56) having a valve port (54) which expires downward to a gas inlet chamber (46) in the gas meter, that are all integrally formed with a synthetic resin. The shutoff valve unit further includes a shutoff valve (81) having a valve body (82) to open/close the valve port (54) and an air-tight main body. The configuration of the shutoff valve unit allows foreign matters or water in the pipe line to fall down in the reducing chamber (52) and prevents a finger or a stick to reach the valve body making it possible to provide a shutoff valve unit which is resistant to foreign matters or water in the pipe line, or misbehavior and yet inexpensive.
