摘要： PURPOSE:To shut off a pipe line with no use of a drive source such as, for example, electric power source, by coupling a breakage detecting member to a shut-off valve. CONSTITUTION:When a part of a gas pipe line 1 which is supported on a bridge 3 is largely deformed together with the bridge 3, a wire 5 is drawn toward the bridge. Since this wire 5 pulls a large diameter shaft 12 on a shaft 10, this large diameter shaft 12 is separated from the shaft 10. Since a spherical valve 11 is released from the holding condition thereof at its opened position, the valve 11 drops by its weight along the shaft 10, and is pushed by the pressure of gas flowing through a gas passage 7, and abuts under pressure against a valve seat 13 positioned on the downstream side to establish its valve closed condition, in order to shut off the gas passage 7, thereby it is possible to prevent gas from jetting through a broken part.

摘要： PROBLEM TO BE SOLVED: To provide a seat structure capable of limiting moving amount of a ball, even if fluid pressure acts on the ball, and preventing abnormal rise of torque and generation of operation defects and having superior sealing property, even if the ball valve is of a floating type. SOLUTION: In this ball valve, in which the ball 14 is incorporated rotatably into a valve casing 12 provided with fluid passages 11 and 11 on both sides, valve seat structures 16 in sliding contact with the ball 14 are provided at positions on both sides sandwiching the balls 14 within the valve casing 12 and the communication of both the fluid passages 11 and 11 is opened/closed by the turning operation of the ball 14, the valve seat structure 16 is constituted by an integral structure of a soft seat 17, in sliding contact with the ball 14 and a core 18 formed, by using a material softer than that of the ball 14, and the core 18 is used also as a stopper of the ball 14, when the soft sheet 17 receives compression by the ball 14.

摘要： PROBLEM TO BE SOLVED: To provide a locking device for a directly operated butterfly valve, which can lock a posture of a valve plate by elastic engagement, release and set the locking mechanism during operation of the valve, and operate the valve with single operation. SOLUTION: A disc 21 which is elstically rotated unitedly with an operation shaft 11 and pressed down and energized by means of a belleville spring 22 is arranged on the operation shaft 11 for opening and closing a valve plate 4 of a butterfly valve, so as to be faced to a fixed portion on the side of a valve main body 1. A plurality of recessions are formed on one of the disc 21 and the fixed poriton on the valve main body 1 side opposed to each other, spaced with specified intevals on the same circumference around an axis of the operation shaft 11. On the other of the opposed surfaces, balls 23 corresponding to the recessions in number and arragement are formed so as to elastically and disengageably engage with the recessions. The recessions and the balls 23 are elastically engaged and disengaged with each other during operation of a the valve.

摘要： PROBLEM TO BE SOLVED: To fuse a gas pipe made of polyethylene and improve the strength of the joined part to the gas pipe by covering the outer surface of a body having a valve seat on the inner periphery surface of a fluid passage with an outer equipped part made of polyethylene having a connection cylinder with a piping on both sides. SOLUTION: A butterfly valve is composed of a body 1, a valve seat 3 provided on the inner periphery surface of the body 1, a shaft 2 penetrating the body 1 in a diameter direction, a valve element 4 fixed on the shaft 2 and an outer equipped part 7 made of polyethylene for covering the body 1. The body 1 is formed by providing a fluid passage 5 in its inside and shaft support cylinders 8, 8 on the upper/lower position of the outer periphery surface. The end of a connection cylinder 6 provided in both sides of the outer equipped part 7 butted against a piping 16 to connect to the gas pipe and this butted part is heated and fused and connected. Thereby, the strength of the joined part can be same as the pipe 16 made of polyethylene and as the outer equipped part 7 is hardly eroded, a long term use is possible.

摘要： PROBLEM TO BE SOLVED: To provide a valve that has higher connection strength to a polyethylene gas pipe and never erodes even by rainwater for its continuous use for a longer period. SOLUTION: A valve is adapted to open or close a gas passage defined inside its body 1, which is made of polyethylene, by the turning motion of its plug 3 interposed in the gas passage. The body 1 is embedded with reinforcing metal cores 9 and is provided with a flanged rubber seal 10 covering the whole peripheral fitting part of the plug 3 to the body 1. The body 1 and a polyethylene gas pipe 7 are easily joined together by a fusion means because of their same material.
