ABSTRACT:
This invention relates to a regulator means for automatically shutting off gas flow in a pipeline during the occurrence of a pressure reducing failure. The regulator means of the invention comprises a body member, a pressure reducing valve device, a piston valve assembly, a timing device, a transmission device, and an overflow control device. The body member is provided with a pressure reducing valve chamber separated by a thin wall from a timing device chamber. The timing device chamber receives the timing device and the transmission device. The transmission device includes a transmission plate and a transmission plate base. A through hole in the body member passes through the thin wall to communicate with a piston valve assembly. The piston valve assembly is mounted in the through hole under the lower side of a pressure reducing valve chamber. A leak-proof diaphragm separates the timing device and transmission device from the piston valve assembly. The transmission device opens the piston valve assembly to permit gas of reduced pressure to flow to the outlet port. The piston valve assembly closes when a pressure reducing failure occurs. An automatic overflow control device is provided at the gas inlet port in the body member. The overflow control device includes an automatic shut-off pipeline passage assembly and a release button. When high pressure gas overflows, the automatic shut-off pipeline passage assembly immediately shuts off the pipeline passage, so that the gas will no longer flow.
