摘要： PROBLEM TO BE SOLVED: To provide a pipe joint which does not lose the function of disassembling the pipe joint even when a corrugated pipe is erroneously pressed into the pipe joint from a state that the connecting construction of the corrugated pipe is completed. SOLUTION: The pipe joint 1 includes: a joint body 2, which has an inner hole 21 into which a flexible pipe 11 is inserted from one end; a seal member 5, which slides in the direction opposite to the insertion direction when the flexible pipe 11 is inserted deep and seals the flexible pipe 11 and the joint body 2; a locking member (retainer) 6, which is adjacent to the seal member 5 and has a claw part 61a locked on the flexible pipe 11. In addition, a locking member diameter re-expansion preventing means 531 is provided between the seal member 5 and the locking member 6. With the sliding action of the seal member 5, the locking member 6 is locked on the flexible pipe 11, while the locking member diameter re-expansion preventing means 531 acts so as to move to a portion between the locking member 6 and the joint body 2.

摘要： PROBLEM TO BE SOLVED: To provide an overflow preventing valve which allows valve opening/closing operation from the outside even if pressure difference inside a pipe cannot lead to valve closing action due to tiny leakage on a secondary side.
SOLUTION: The overflow preventing valve cuts off passage of fluid by abutment of a valve element onto a valve seat when the downstream side pressure inside a pipe drops. During normal circulation, a spherical valve element 60 is biased by a coil spring 70 in a direction separating from the valve seat 43, and retained by a supporting member 52. When carrying out the maintenance due to occurrence of tiny leakage on a secondary side, the valve closing operation is manually executed. By using magnetic force generated by a ring-shaped external magnetic circuit member 8 slidably provided in the outside of the valve and an internal magnetic circuit member 6 provided to the inside of the spherical valve element 60, the spherical valve element 60 is seated on the valve seat 43 against the biasing force of the coil spring 70 to perform the valve closing operation.

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 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 corrugated tube joint which is simply constructed and can be connected easily. SOLUTION: A ring groove 12 is dug in an inner hole portion B of a joint body 10 in a radially outer direction. On the other hand, a ring groove 23 is dug on the outer periphery of a retainer case 18 in a radially inner direction. An inner periphery portion of a stop ring 24 is fitted in the ring 23. Firstly, a retainer 17 is inserted into a corrugated tube T, then the retainer 17 is mounted on the retainer case 18. Further, when the corrugated tube T and the like are inserted into the joint body 10, the outer periphery of the stop ring 24 is fitted into the ring groove 12, prohibiting the retainer case 18 from being disassembled.

摘要： PROBLEM TO BE SOLVED: To provide a corrugate pipe joint which can easily and rapidly achieve the connecting work with a simple structure. SOLUTION: The corrugate pipe joint 10 comprises a joint body 11 having a connection part to other pipes and an inner hole in which an end of a corrugate pipe is inserted and two-split retainers 13. Halves of the two-split retainers 13 are connected to each other at a hinge part. The retainers 13 can be opened with the hinge part as a supporting point. After the retainers 13 are opened, one half claw 13f of the retainers is inserted in an annular recessed part on the outer surface of a corrugate tube T. Then, the retainers 13 are closed, the other half claw 13f is inserted in the annular recessed part, and the retainers 13 are fixed to the joint body 11 to connect the joint to the corrugate tube T. Any complicated mechanism to allow the retainers to operate and an annular projecting part of the corrugate tube to pass can be dispensed with, and the structure of the joint can be simplified.

摘要： PROBLEM TO BE SOLVED: To provide a corrugated pipe joint permitting a connecting operation to be carried out with a good execution property without using tools such as a spanner and a wrench. SOLUTION: The corrugated pipe joint 10 comprises a joint body 11, a retainer 12, a casing 20 and the like. The retainer 12 comprises retainer members 12A, 12B each formed of a stainless steel plate. The retainer members 12A, 12B are free to slide in opposite directions as they are energized by an elastic member 19. The retainer members 12A, 12B are slid in the opposite directions to cause rings A1, A2 to become concentric with each other to pass the annular projection T2 of a corrugated pipe T through both rings A1, B1. The pawls A4, B4 of the retainer members 12A, 12B are inserted into recesses T1 in the corrugated pipe T and catch the corrugated pipe T while in axial symmetry to each other. Thus, the corrugated pipe T can be fixed in place without overturning.
