摘要： PROBLEM TO BE SOLVED: To provide a joint for a gas pipe, which joint can easily confirm whether or not a packing is mounted on one end surface of a joint body.
SOLUTION: The joint is configured such that a straight portion 1b having a specified outside diameter is formed on the outside peripheral surface of the lower end portion of the joint body 1. A snap ring 3 is arranged on the outside peripheral surface of the straight portion 1b. An annular projection 2b is formed on the inside peripheral surface of the upper end portion of a connecting nut 2 so as to rotatably and movably fit on the straight portion 1b located above the snap ring 3. A female thread portion 2c is formed on the inside peripheral surface of the lower end portion of the connecting nut 2. A recess 1h is formed on the upper side of the straight portion 1b of the joint body 1. In the joint, the inside diameter of the annular projection 2b is set to be larger than the outside diameter of the recess 1h and the inside diameter of the female thread portion 2c is set to be larger than the outside diameter of the snap ring 3 such that the connecting nut 2 may tilt until the outside peripheral surface of a packing 4 mounted on the lower end surface of the joint body 1 is exposed to the outside in the radial direction from one side portion of the connecting nut 2.

摘要： PROBLEM TO BE SOLVED: To enable the securing of a predetermined inserting quantity of a metal bellows pipe by making such a structure that the inserting feeling can be obtained at the completion of inserting the metal bellows pipe, eliminating the need for marking, and to solve the problem that inserting is insufficient, even in a narrow place, a closed place, a dark place, etc.
SOLUTION: A snap ring 5 having an outside diameter which is greater than a root inside diameter and smaller than a height inside diameter of the metal bellows pipe 7 is fitted into a deeper position than a seal packing 3 on the circumference of an inner cylinder 10 of a pipe joint body 1. An inserting resistance value for inserting the metal bellows pipe 7 into the snap ring 5 is set greater than an inserting resistance value for inserting it into an annular holder 4. An exposed end 7a of the metal bellows pipe 7 is inserted into a push ring 2, the annular holder 4, and a seal packing 3 successively. Reaching the snap ring 5, the inserting resistance becomes a maximum when the endmost root of the exposed end 7a of the metal bellows pipe 7 exceeds the snap ring 5, and the predetermined inserting quantity can be confirmed to obtain by the inserting feeling directly after going beyond there.

摘要： PROBLEM TO BE SOLVED: To provide a gas leakage prevention device of which installation can be facilitated by incorporating a valve means into a mouth pipe at the entrance of a gas meter, and at the same time, which can surely prevent a gas leakage even if the gas meter is damaged.
SOLUTION: The mouth pipe 2 at the entrance of the gas meter 1 is at least formed of high melting point metals such as steel. The valve means 4 capable of opening and closing a flow passage 3 inside the mouth pipe 2 is internally fitted inside the mouth pipe 2 at the entrance. The gas flow is limited or blocked by blocking the valve means 4 by holding the valve means 4 so as to normally make the valve means 4 to be in an open state, and at the same time, by releasing the holding of a holding means 5 when exposed to a higher temperature.

摘要： PROBLEM TO BE SOLVED: To provide a gas leakage preventing device capable of preventing the leakage of a gas by limiting or shutting off the gas circulation when being exposed to an abnormally high temperature by fire and the like, and being recovered even when it has been operated once.
SOLUTION: This gas leakage preventing device comprises a valve element for limiting or shutting off the circulation of a gas when a gas transporting pipe is exposed to an abnormally high temperature. A valve seat 6 openable and closeable by the valve element 5 is mounted in a channel 4 of a gas pipe 3. The valve element 5 is ordinarily mounted in a state of being separated from the valve seat 6 and held by a holding member 7 made out of a shape-memory alloy. The holding member 7 of the shape-memory alloy is deformed when exposed to high temperature, whereby the valve element 5 is released to close the valve seat 6.
