Abstract:
It is an object of the present invention to provide a shutoff valve unit which can be easily attached to a gas meter whose casing is formed with a press worked thin plate and has a resistance to foreign materials or water in a piping or a tamper. An inlet pipe 51, a speed reducing chamber 52 arranged in a lower part of the inlet pipe and having a flow passage sectional area larger than a flow passage sectional area of the inlet pipe 51, a transverse passage 53 opened substantially in a horizontal direction from a side surface at a position higher than a bottom surface 52a and a valve chamber 56 having a valve seat hole 54 opened downward to a gas introducing chamber 46 in the gas meter are integrally formed with a synthetic resin, and a shutoff valve 81 is provided which has a valve disk 82 for opening and closing the valve seat hole 54 and incorporates an air-tight structure in a main body to form a shutoff valve unit. Accordingly, the foreign materials or water in the piping drop in the speed reducing chamber 52, and even when a finger or a rod shaped member is inserted, the valve disk 82 cannot be easily touched. Thus, an inexpensive shutoff valve unit can be provided which has the resistance to the foreign materials or the water in the piping and the tamper.
