摘要： PROBLEM TO BE SOLVED: To provide an insert type pipe joint capable of providing secure sealing by merely inserting bellows pipe into a joint pipe, and having a simple and safe structure. SOLUTION: This insert type pipe joint for connecting the bellows pipe F having recessed and projecting portions 18, 20 in corrugated form on an outer periphery comprises a joint main body 26 in which a pipe insertion aperture 24 for inserting the bellows pipe is formed, and an inner wall surface is stepwise formed; a nut member 30 in the ring shape fixed on a leading end of the joint body; packing members 40, 42 arranged on an inner wall surface of the joint body; and a retainer member 50 in the shape of ring, a leading portion slidably coming into contact with an inner wall of the nut member, the base end being supported to be in contact with the packing member, when the bellows pipe is inserted, the retainer member being applied to the leading end of the bellows pipe, and one portion of the retainer being elastically enlarged and contracted in a radial direction of the bellows pipe, thereby allowing the bellows pipe to be insert into the inside thereof. The nut member is formed with a fallout preventing taper surface 60 which deforms the retainer member in a diametrically contracting direction when a force is exerted to the bellows pipe in a drawing direction. Thus, the bellows pipe is surely sealed and attached by merely inserting it into the joint body.

摘要： PROBLEM TO BE SOLVED: To provide an inset type pipe joint capable of providing secure sealing by merely inserting a bellows pipe into a joint body, and having a simple and safe structure.
SOLUTION: This insert type pipe joint for connecting the bellows pipe F having recessed and projecting portions 18, 20 in corrugated form on an outer periphery, comprises a joint main body 26 in which a pipe insertion aperture 24 for inserting the bellows pipe is formed and an inner wall surface is stepwise formed; a packing member 32 in the ring shape slidably arranged along the inner wall surface of the joint body; a nut member 30 in the ring shape arranged on a leading end of the joint body and engaged with the packing member to be slidable integrally with the packing member; an engaging protrusion 62 arranged on the packing member and applied to a leading end of the bellows pipe when the bellows pipe is inserted; and a stop ring 44 for preventing fallout by engaging with the nut member when the nut member is inserted into the joint body. The nut member is formed with a fallout preventing taper surface 56 which deforms the retainer member in a diametrically contracting direction to prevent the bellows pipe from falling out when force is exerted to the bellows pipe in a drawing direction and pushes it into a recessed portion of the bellows pipe.

摘要： PROBLEM TO BE SOLVED: To provide an insert type pipe joint capable of providing secure sealing and attachment by merely inserting a bellows pipe into a joint body, and having a simple and safe structure.
SOLUTION: This insert type pipe joint 16 comprises the joint body 26; a nut member 30 in the ring shape fixed on a leading end of the joint body; packing members 40, 42; a guide member 44 in the ring shape; and a retainer member 50 in the oil ring shape. The retainer member is placed on a housing groove 48 in the ring shape arranged on an outer periphery surface of the guide member at an initial time, and when the bellows pipe is inserted, the retainer is applied to a leading end of the packing member to be pushed out from the housing groove, and it allows the bellows pipe to be inserted into an inside, while elastically enlarging and contracting in a radial direction of the bellows pipe. The nut member 30 is formed with a fallout preventing taper surface 52 which prevents the retainer member from deforming in a diametrically enlarging direction when force is exerted to the bellows pipes in a drawing direction. Thus secure sealing and attachment are provided by merely inserting the bellows pipe in the joint body.

摘要： PROBLEM TO BE SOLVED: To provide a gas stopper having both waterproofing function and permeability of air in a body.
SOLUTION: The gas stopper 1 can prevent water from entering in a space inside the stopper by an O ring 61, thereby preventing the inside of the socket from generating rust by corrosion and depositing scale. Therefore, blemish on both surfaces 15, 20a caused by biting rust or the like between a stopper body sliding part 15 of the body 10 and an outer peripheral surface 20a of a stopper body 20 can be prevented, which leads to less risk of causing malfunction, gas leakage or the like. In the gas stopper 1, permeability between the inside and outside of the stopper is secured by a ventilating member 60. Should gas leakage occur, gas leaks out of the ventilating member 60 so as to accurately detect the gas leakage by inspection after completion of piping.

摘要： PROBLEM TO BE SOLVED: To provide a gas cock of which the operability and durability are not remarkably impaired even when it is exposed to high temperature like never before, and of which the fracture and the inability to rotate hardly occur.
SOLUTION: A gas flow channel 14 and a cock body sliding face 15 are formed inside of a main body 10 of this gas cock 1. In the main body 10, a clock body 30 having an outer sliding face 31 is rotatably mounted. The outer sliding face 31 of the cock body 30 is provided with recessed parts 35 as storage parts of lubricant including graphite, in a dispersed state, and is coated with a graphite film. This gas cock 1 can reduce the probability of seizure of the main body 10 and the cock body 30 under high temperature environment, and can be rotated with low operating force.

摘要： PROBLEM TO BE SOLVED: To provide a branch joint clamp capable of fitting and fixing a saddle type fusion joint into an existing pipe smoothly and securely. SOLUTION: When using this clamp 100, the clamp is first provided while an opening part 14 of a saddle part 13 of the joint 10 is applied to an outer face of the existing pipe 1. When a pair of engaging members 111, 121 of the clamp 100 are drawn close to a pressing member 130, the opening part 14 of the saddle part 13 is enlarged along the outer face of the existing pipe 1. After the opening part 14 crosses the maximum diameter part of the existing pipe 1 and is fitted, an innermost part of the saddle part 13 is applied to the existing pipe 1, and a pair of opening fringes 15 of the saddle part 13 are drawn to an inner side for clamping. Fitting and fixation of the joint 10 into the existing pipe 1 are smoothly and securely performed by this clamp 100. COPYRIGHT: (C)2005,JPO&NCIPI
