摘要： PROBLEM TO BE SOLVED: To facilitate an assembly work by inserting an insertion member from a communication hole to an inner circumferential groove, engaging it with parts and basic members, and forming a fixing means of the parts to simplify the connection structure of a suspension unit to a gas plug. SOLUTION: An opening is formed in an end face respectively in a cross section 22 and leg parts 21, 31, and a left end of the section 22 is opened in the horizontal direction, a right end is opened in both upper and lower directions, and the respective lower ends of the leg parts 21, 31 are opened downwardly. Gas communication passages 19a and 33a to communicate right and left openings with each other are formed between the right and left ends of the section 22 and the leg parts 21 and 31 close to the ends. The opening at the left end of the section 22 is an insertion hole 19b in which an insertion part of a socket part of the gas plug is inserted. A groove 19c cut semi-circularly in the groove section is formed in the circumferential direction of the section of the opening in an inner surface of the insertion hole 19b. The structure of the connections of the suspension unit to the gas plug can be simplified, and the assembly work can be achieved in an extremely easy manner.

摘要： PROBLEM TO BE SOLVED: To provide a overflow preventing valve preventing an occurrence of a turbulent flow directly beneath a valve element in a normal flow state for minimizing flow resistance of passing fluid, capable of long term usage without causing malfunction of the valve element, and capable of cutting off a flow of fluid without delay in an emergency such as pipe breakage. SOLUTION: In this overflow preventing valve, when a downstream side pressure inside a pipe with flowing fluid abnormally drops, the valve element abuts to a valve seat for cutting off passage of the fluid, and it is characterized by that, during normal flowing, the valve element is supported by a support part so that a part of the valve element covers a perspective cross section of the valve seat and the valve element is energized by an elastic member in a direction separating from the valve seat, and an orifice of a valve through which the fluid passes is composed of a passage sectional area around the valve element. It is also characterized by that the valve element and the support part are composed in a relationship so that a fluid passage sectional area between a pipe inner face and the valve element and a fluid passage sectional area between the valve element and the valve seat are substantially the same or within 10% in a state of a normal flow inside the pipe.

摘要： PROBLEM TO BE SOLVED: To provide a heat source machine reduced in its installation space and easy to install. SOLUTION: A heat source machine 50 is constituted of a hot water making part A and a metering part B. The hot water making part A is formed as one unit by housing a hot water heat exchanger 31 in a housing 30 and the metering part B is formed as one unit by housing a gas meter 12 and a water meter 14 in a housing 1. The hot water making part A and the metering part B are connected through the pipings of both of them. Since both meters can be collectively arranged by arranging the metering part B, the installation and execution properties are improved and an installation space and the number of members required in installation can be reduced. Further, the heat source machine can be rapidly and easily installed by connecting the hot water making part A and the metering part B.

摘要： PROBLEM TO BE SOLVED: To provide a corrugated pipe joint permitting a connecting operation with a good construction property without using tools such as a spanner and a wrench, etc. SOLUTION: The corrugated pipe joint 10 comprises a joint body 11, retainers 15, a case 19 and the like. Each retainer 15 is a member made from stainless, in which a locking part 15a, a pawl 15b and a connection 15c are formed integrally with one another. The locking parts 15a of the retainers 15 are integrally linked with one another by ring-shaped elastic members 14. When the case 19 is threaded into the joint body 11, a taper part 19a at the lower end of the case 19 makes contact with the tapered surface 15d of each retainer 15, which is in turn tilted in the direction of insertion of a corrugated pipe T. When the tapered part 19a is in contact with the tapered surface 15d, each retainer 15 is not tilted in the opposite direction (withdrawal direction) to the direction of insertion of the corrugated pipe T. This allows a connecting operation to be carried out while preventing inadvertent disconnection of the corrugated pipe T.
