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： PURPOSE:To provide a cheap combustion assisting agent having an excellent performance by using, as main components, a solution which is obtained by treating sea water or the like with the use of an alkalescent agent made of a baked mesh of a natural synthetic mineral source such as, IOH stone or the like, and a treated substance which is obtained by treating hydrocarbon group oil in a similar manner as mentioned above. CONSTITUTION:Water, preferably sea water is added and treated with an alkalescent agent made of a baked mesh of a neutral type natural synthetic mineral source such as mineral stone so-called 'IOH stone' or the like, having a deodorizing and anti- rusting reaction due to a contained substance of ionic type, germanium type, radium type or the like, so as to prepare a solution (a). Further, hydrocarbon group oil is treated with the above-mentioned alkalescent agent so as to prepare a solution (b). These solutions (a, b) are mixed with each other and agitated at a suitable ratio, and then a strong alkaline agent obtained by baking a suitable high calcium containing substance at a high temperature is added as a reaction promoting agent into thus agitated solution by a suitable amount. These materials are further agitated so as to be reacted with each other, thereby it is possible to obtain a desired combustion assisting agent.

摘要： PURPOSE:To heat the water for a bath, the hot water for supply and the hot water for space heater by steam in higher efficiency, by composing a heating device in such a manner that the lower part of a sealed container is used as a liquid heating medium part, and the upper part as a reduced pressure steam chamber, a circulating pipe to heat the bath water is arranged in the reduced pressure steam chamber, and combustion exhaust gas is passed through the outgoing and the returning passage of a circulating pipe. CONSTITUTION:When the pressure in a steam chamber 5 is reduced and a water A is heated by a heating device 3, steam corresponding to the temperature is generated, filling the steam chamber 5. With the steam, the water in a bath water heater 7 and the heater 8 for hot water supply is heated, the steam is condensed, and a part of condensed water is returned to a liquid heating medium part 4, heated further until it is evaporated. Another part of condensed water is collected into water collecting recess 12. The condensed water drops and the collected water in the water collecting recess 12 are heated and evaporated by the potential heat of combustion exhaust gas, passing through an exhaust passage 9. With such an arrangement, the steam can be generated efficiently, and the water in a bath, the hot water for water for supply, and the hot water for space heater can be heated by the steam.
