摘要： PURPOSE:To make it possible to perform gas meter replacing work even during the absence of family members, by mounting a bag to a shutter apparatus capable of opening and closing the hole corresponding to a meter testing port and inserting a no-blow tool in the bag to perform the replacement of a gas meter. CONSTITUTION:At first, a shutter apparatus 4 is mounted to the meter testing port 2 of a gas pipe (b) in such a state that an opening and closing plate 6 is closed and, next, the opening and closing late 16 is opened to detach the plug X of the test port 2. Next, a bag 12 is mounted to the shutter apparatus 4 to take out the plug X into the bag 12 and the side of the stopper 16 of a no-blow tool is inserted in a gas pipe (b) through the hole of the shutter apparatus 4 and the testing port 2 and, subsequently, the stopper 16 is expanded while gas is made to flow in the gas pipe (b) from a nozzle pipe 15 to stop the gas flowing through a gas meter and an original stopper is closed to detach the gas meter to perform the replacement or repairing of the gas meter. Therefore, the gas meter is again mounted to open the original stopper and the gas is made to flow to the side of the gas meter and air purge is performed through the air purge cock 9 of the shutter apparatus 4.

摘要： PURPOSE:To enable an excessive outgoing preventing mechanism to be operated in a stable manner even if a gas cock is mounted in any orientation, by a method wherein the valve body of the excessive outgoing preventing mechanism is held in a place through the force of an expandable resilient product. CONSTITUTION:A ball valve 12 of an excessive outgoing preventing mechanism is contained in a gas passage 2 of a gas cock 1, and a cylinder 8 having a valve seat 10, on which the ball valve 12 is seated, is secured thereto. A through- hole is formed in the ball valve 12, and an expandable resilient product 13, e.g., a coil spring, is extended through the through-hole. Both ends of the expandable resilient product 13 are respectively secured in holes 15 in the cylinder 8 by means of a screw 14, and this causes the ball valve 12 to be held in a place.

摘要： PURPOSE:To restrain the initial moving torque of a plug from increasing, by constituting the plug with a thine wall plug body made of metal and a flow passage forming member disposed inside of the plug body and made of materials which is softer than the material of the plug body. CONSTITUTION:A plug 20 is rotatably disposed in a storage space 11 in a gas cock body 10. The plug 20 is composed of a brass plug body 21, and a flow passage forming member 25 disposed inside of the plug body 21. The flow passage forming member 25 is made of materials which is softer than that of the plug body 21, such as resin or the like. The fluid passage forming member 25 is cylindrical so as to have an upper wall part 25a, a lower wall part 25b and a pair of side wall parts 25c opposed to each other. With this arrangement the fastening force for the plug 20 by the gas cock body 10 may be relieved due to the resiliency of the plug body 20, thereby it is possible to restrain the initial torque of the plug from increasing.

摘要： PURPOSE:To prevent gas outflow in spite of the presence of a leaking source during the stop time of a gas device by installing solenoid valves to a header individually in such a manner that a header and gas plugs are connected individually with independent inner tubes and the solenoid valves are opened and closed under interlocking with the operation of the gas utensils. CONSTITUTION:At the outlet pipe side of a gas meter 2, a header 5 comprising solenoid valves 7 individually is installed and this header and gas plugs placed at each room are connected individually with flexible inner tubes 8 in which signal wires 9 are inserted, while a gas plug 12 and gas utensil 23 are connected with gas hose 16 including signal wire 17. And the operation signal of the gas utensil 23 is transmitted to a controller 10 through the signal wire 17 in the gas hose 16 and the signal wire 9 in the inner tube 8 and the solenoid valve 7 at the header 5 is enabled to open and close individually. As a result, even if any leaking source is present an inner tube, gas hose, connecting part of a gas plug, or connecting part of a gas utensil, gas does not flow out and safety is ensured.

摘要： PURPOSE:To prevent mutual biting of sliding surfaces by fixing a cock holder to the sliding surface of a main body, supporting a cock body through a ring, and uniformalizing a grease film on the sliding surface. CONSTITUTION:A cock is divided into a cock body 11 and a cock holder 12, which are laid one over the other to be subjected to machining or lapping. After the completion of machining, the cock holder 12 is installed at the sliding surface 9 of the main body. Further, a metallic or synthetic resin ring 13 is installed thereon, grease is applied to the sliding surface of the cock holder 11, and the cock holder is assembled to the main body. The relation ship between the grease layer A and the thickness of the ring 13 is that when a taper is 1/N, B=AX2N.

摘要： PURPOSE:To achieve a reliable function irrespective of the installing direction by supporting a fused valve where the distance to a valve seat will vary in dependence upon the installing direction in a cylinder through a spring. CONSTITUTION:An overflow prevention valve 6 comprises a fixed cylinder 7, a movable cylinder 8 assembled slidably in the fixed cylinder 7 and a fused valve 10 abutable tightly against a valve seat 9 in the movable cylinder 8 from the upstream side. The fused valve 10 is supported by a spring 13 and constructed such that the distance between said valve 10 and the valve seat 9 will vary in dependence upon the buoyancy functioning onto the fused valve 10. With such arrangement, the variation of the operating point due to the self-weight of the fused valve 10 can be prevented irrespective of the installing direction of valve resulting in a reliable function at all times.
