摘要： PROBLEM TO BE SOLVED: To provide a gas valve integrated type gas meter mounting unit easily mounting a small-sized gas meter having gas meter inlet and outlet facing downward.
SOLUTION: This gas meter mounting unit 1 is equipped with an inlet pipe part 10 having a connection part 60 or the like to the gas meter inlet 51, an output pipe part 40 having a connection part 70 or the like to the gas meter outlet 52, end face packings 66. 76 mounted on the periphery of each connection part of the inlet pipe part and the output pipe part, a connection member 20 for connecting the inlet pipe part to the output pipe part, a support member 48 for supporting the inlet pipe part and the output pipe part and connecting each part to a building wall or the like, and fastening members 22, 24, 26 between the gas meter and the connection member 20. Since the gas meter is fastened with the connection member, the gas meter inlet and outlet can be connected to both pipe parts. Consequently, centering between both pipe parts and the gas meter inlet and outlet during a connection work which is necessary hitherto is not required, allowing even a worker unskilled in the gas meter mounting work to easily mount the gas meter.

摘要： PROBLEM TO BE SOLVED: To smoothly perform connection work.
SOLUTION: In a plug-in joint 1 for a corrugated pipe, the corrugated pipe T is inserted into a joint body 10 from a retainer pushing sleeve 50 inner hole, and respective pins 73 are elastically deformed and bent to the inner side when an annular protrusion T' is abutted to the respective pins 73 (pin group) of a stopper 70. At that time, respective split circumferential pieces 75 with which at least a part of a root part of the respective pins 73 is brought into contact is deformed at a root of a ring part 71, and is opened to the outer side. When the annular protrusion T' gets over the inner side of the stopper 70, the pin group of the stopper 70 and the respective split circumferential pieces 75 are recovered to the original state. When the pin group is elastically deformed and recovered to the original state, a worker inserting the corrugated pipe T can feel passing feeling by the sound and/or the touch, and can confirm that the annular protrusion T' passes the stopper 70 by the passing feeling. After the annular protrusion T' gets over the pin group, an outer side of an annular recess T" is surrounded by the stopper 70, and the pin group goes into the annular recess T" and the corrugated pipe is prevented from slipping out until it is fixed.

摘要： PURPOSE: To provide a joint allowing the insertion of a corrugated pipe in a joint body for connection via a nut tightened without any need of an disassembly ensuring a high sealing function at a section in contact with the corrugated pipe, and further allowing the corrugated pipe to be easily pulled out even after tightening the nut for making judgement as to whether a proper connection is attained, when the corrugated pipe is not inserted deep in the joint. CONSTITUTION: This joint is formed out of a joint body 1, a sleeve 2 for holding a corrugated pipe 4, a nut 3 screwed to the joint body 1 and a spacer ring 5. The joint body 1 internally has a shoulder 14, and an inner tapered surface 15, an annular recessed groove 16 and a narrow internal thread are formed in order from the shoulder 14. Also, a projection 23 is formed on one end of the sleeve 2, and can enter the trough of the corrugated pipe 4 on an elastic pivotal motion. The nut 3 holds the projection 23 of the sleeve 2 at a position faced to the recessed groove 16, and has a pushing surface 33 to contact and push the contact surface 24 of the sleeve 2.

摘要： PURPOSE:To permit the airtight connection by installing a sleeve which intrudes into the gap between a joint body having an annular recessed groove and a corrugated pipe, means for holding the projecting outer surface of the sleeve, and a nut having a flange surface, and inserting the nut into the coupling body, and tightening the nut. CONSTITUTION:In the state where a nut 3 is loosely screwed into a joint body 1, a flexible corrugated pipe 4 from which several threads portion of a resin cover 41 at the top end part is removed is inserted from the opened hole of a nut 4, and then the top end of the pipe 4 or the thread 42 at the top end pushes a projection 23 at the top end of a sleeve, and the sleeve advances to the innermost position in a through hole 11. Further, the projection 23 of the sleeve is pushed by the thread 42 of the pipe 4, and the outer surface of the projection 23 of the sleeve is drawn into an annular recessed groove 16, and spread, together with the pivot movement, and the inner surface of the projection 23 rides over the thread 42 of the pipe 4. When the nut 3 is tightened, the sleeve is pushed to the shoulder part 14 inside the through hole 11, and drawn in the radial direction by a taper surface 15, and the end surface of the pipe 4 is collapsed to the airtight surface of the shoulder part 14, and airtightness can be maintained.

摘要： PURPOSE:To improve connection workability by a method wherein a coupling for a flexible pipe comprises a pull-off preventing tool having kerves axially formed in a periphery and inserted externally of a flexible pipe, a nut rotatably engaged therewith, and a coupling body joined in a screwed-in state with the nut and having the fitting-in inner surface of a pull-off preventing tool and the collision surface of a pipe. CONSTITUTION:When a flexible pipe 50 is inserted from the rear end part of a nut 20, the tip part 51 thereof is inserted in a coupling body 10 as the inner surface of a slip-off preventing tool 30 is forcibly spread. The tip part is collided with the annular packing 16 of a collision wall 14 and the slip-off preventing tool 30 is fitted in the corrugated surface of the pipe 50 for locking. When the nut 20 is rotated, the front end face of the nut 20 is brought into contact with the kerf groove 34 of the guide 32 of the slip-off preventing tool 30. The slip-off preventing tool 30 is pressed in a fit-in inner surface 13 and a pipe end part 51 is pressed toward the collision wall 14 side by a lock part 31 as the flexible pipe 50 is locked by the lock part. The slip-off preventing tool 30 is contracted on the fit-in inner surface 13 and no rotation is effected by frictional resistance. One crest of the pipe end part 51 is squeezed to form the end part 52 of a pressure adhesion tube. The flexible pipe 50 and the coupling body 10 are sealed and accurately connected with the flexible pipe 50.

摘要： PROBLEM TO BE SOLVED: To provide a coupling having a function to be connected with high sealing ability without a labor by inserting a corrugated pipe in a preassembled coupling and thereafter slightly further fastening a nut and besides detect it at a current time whether the corrugated pipe is correctly inserted. SOLUTION: A coupling to interconnect corrugated pipes comprises a coupling body 1; a sleeve 2 to hold the end of a corrugated pipe 4; and a nut 3 screwed in the coupling body 1. In which case, the coupling body 1 has a shoulder part 14 formed at the inside and having an airtight surface, an inner surface taper surface adjoining the shoulder part 14, and an annular recessed groove adjoining the taper surface. The sleeve 2 has a protrusion formed from an end part toward the internal part in a radial direction, and the protrusion enters the root of the flexible corrugated pipe 4 through resilient pivot movement. Further, the nut 3 has a claw, holding the outer surface of the protrusion of the sleeve 2 in a place corresponding to the annular recessed groove, a press surface pressed against the sleeve 2, and a fit-in groove in which the outer peripheral surface of the rear part of the sleeve 2 is fitted.
