摘要： PROBLEM TO BE SOLVED: To provide a pipe joint which permits the installation works of pipe members to be smoothly carried out, and concurrently can reduce production costs. SOLUTION: In order to make connection at the end part of a pipe member 1 over the outer circumferential surface of which each projected strap part 1a and each recessed strap part 1b are alternately laid along the circumferential direction, the pipe joint is equipped with a pipe joint main body 2 provided with a male screw part 21, and with a cylindrical part 22, a box shaped nut 3 provided with a hole part 32, and with a female screw part, and with a sleeve 4 which is outwardly fitted in the pipe member 1 while being supported by an abutting part at the main body side of the pipe joint main body 2 and an abutting part at the nut side of the box shaped nut 3. In the pipe joint T where the main body side abutting part that is formed into a taper shape, or a sleeve end part to be supported by the nut side abutting part, is deformed in the radial direction toward the inner side by letting the pipe joint main body 2 and the box shaped nut 3 be threadedly engaged with each other so as to be engaged with the recessed strap parts 1b, the nut side abutting part 33 is formed out of a presser ring 33A capable of pressing a sleeve 4 while being slid with the sleeve 4.

摘要： PURPOSE:To apply lubricant oil to a closing piece under the condition free from gas leakage, with favorable work efficiency and without inconveniencing gas supply by supplying purge gas to contain and seal transport gas contained in a work case into a container after fitting closing piece to a main body of a cock and before removing the work case from the main body of the cock. CONSTITUTION:Work is done such that, before fitting a closing piece 20 to a main body of a cock 4 and under the condition of the closing piece being attached to a closing piece inserting tool E, a work case D housing the closing piece 20 is connected in airtight condition to a shutoff tool C, and the shutoff tool C is opened. After attaching the closing piece 20 to the cock main body 4 and before removing the work case D from the cock main body 4, purge gas is sent and sealed into the work case D to send transport gas contained in the work case D into a transport gas collection container 17. Repair of the gas cock is made under the condition free from gas leakage, with favorable work efficiency, and without inconveniencing customers as a result of accidental gas shutoff.

摘要： PURPOSE:To apply lubricant oil to a closing piece under the condition free from gas leakage, with favorable work efficiency and without inconveniencing gas supply by supplying purge gas to contain and seal transport gas contained in a work case into a container, and removing the work case from a main body of a cock. CONSTITUTION:Before removing a work case 1 from a main body of a cock, purge gas is supplied into the work case 1 and transport gas in the work case 1 is sent out and sealed in a transport gas collection container 19 connected to the work case 1. Therefore, problems associated with gas leakage are securely prevented: a workman cannot misjudge the dissipation of the transport gas out of the work case 1 as gas leakage when the work case 1 is removed, and accidental automatic gas supply stop due to a gas leak detector does not occur. Repair of the gas cock is made under the condition free from gas leakage, with favorable work efficiency, and without inconveniencing customers as a result of accidental gas shutoff.

摘要： PURPOSE:To make the thickness of coating uniform by a method wherein valve plugs are pinched by split molds, which have a resin pouring port and an gas discharging port and make a uniform gap between the outside surface of the main body of any one of pipe joints and the inside surfaces of the molds, and finally two-part reaction type resin is forced in the gap. CONSTITUTION:A pref-formed polyacetal resin packing 2 is fitted to the rotary part of a cock and rubber rings 3 are fitted to both the ends of the cock as the airtight sealing means under the condition that the cock 1 is pinched horizontally from both sides by molds. After that, the molds and the cocks 1 as a body to be coated are heated up to 80+ or -5 deg.C. Under the above-mentioned condition, pressurized polyurethane- based two-part reaction type resin liquid mixed with coal tar is forced from a resin pouring port, which is provided on the lower part of the matching surfaces of the molds, in a cavity so as to fill the cavity with the resin liquid by displacing the air in the cavity in about 20 seconds. After being held at 50 deg.C for 3 hours in order to complete the cure reaction of the resin liquid, the molds are dismantled. The projections of resin cured in the resin pouring port and in a gas discharging port of the mold and cut off, resulting in leaving the resin pouring port mark 4 and the gas discharging port mark 3 on the cock as cooling marks.

摘要： PURPOSE:To obtain a safe and low-cost combustion assisting agent by ultrasonically treating a solution which is obtained by treating sea water or fresh water with an alkalescent agent formed by baking the mesh of a natural overall mineral source, and a solution obtained by treating a hydrocarbon group oil with the same alkalescent agent. CONSTITUTION:An alkalescent agent formed by baking the mesh of a neutral natural overall mineral source (e.g., 'Iohseki') having deodorant and rust preventing reaction due to contained substances such as ion, germanium, radium, etc. is added to sea water or fresh water to obtain a solution (a). And, a solution (b) formed by treating a hydrocarbon group oil with the same alkalescent agent is mixed with this solution (a), which are stirred and, then, ultrasonically treated, to refine a combustion assisting agent.

摘要： PURPOSE:To simplify installation of a piping and to facilitate maintenance and servicing, by a method wherein a male screw is situated to the end part of a pipe connection part, and the outer peripheral surface, except the male screw, of a valve body is covered with a synthetic resin layer. CONSTITUTION:A valve body 1 is integrally formed by using a metallic member, e.g. cast iron, and is provided on both ends with pipe connection parts 11. The valve body 1 is provided approximately at its central part with a stem support part 12. A male screw 110 is situated to the outer periphery of the end part of the pipe connection part 11, and the outer peripheral surface, except the male screw 110, of the valve body 1 is covered by painting power of polyvinyl chloride resin or with a synthetic resin layer 10 of vinyl chloride resin, polyethylene resin. This constitution eliminates an anticorrosion work in which a seal tape is wound around the outer peripheral surface of the valve body after installation of a piping.

摘要： PURPOSE:To safely prevent an overcurrent from flowing through a hydraulic pump, by providing a pressure switch and a detection switch for detecting the rotation of an arm and by stopping a motor through the pressure switch when the detection switch is defective. CONSTITUTION:Oil in the piston chamber C1 of a cylinder 4 and the piston cylinder C3 of another cylinder 5 flows into a housing 2a. When a rod 43 is moved rightward and a shutoff valve is fully opened, a switch 7 for detecting the rotational position of an arm 60 is opened to stop a motor to keep the shutoff valve open. When electric power is cut off, relief valves 82, 92, 93 are deenergized so that the relief valves 82, 92, 93 are fully opened, oil in piston chambers C4, C2 flows into the housing 2a and the piston chamber C1, C3 and pistons 42, 52 close the shutoff valve by the thrusting force of a spring 44. According to this constitution, an overcurrent is safely prevented from flowing through a hydraulic pump.
