摘要： PURPOSE:To obtain a pipe joint which can be inspected and cleaned up and also bisected, by connecting the inner tube and the outer tube of a double drain riser forming a vent path with an insertion type joint and a freely sliding joint having an opening or the like respectively. CONSTITUTION:When the upper drain riser 1A and the lower drain riser 1B constituting a double-tube are connected, mutual inner tubes 7 are united to be able to slide with a slip-on-type pipe joint 20. And a stopper 40 is provided on the outer tube 9 forming a vent path and a pipe joint 10 provided with an opening 34, a flange 36, a cover 50, etc., is attached so as to freely slide and the upper and lower risers 1A, 1B are connected. Then the cover 50 and the joint 20 can be removed to inspect the pipe inside and clean up the inside by insertion of a jet cleaning tool and also a branch pipe can be attached at the flange 36. In this way, a pipe joint for multi-purpose can be obtained.

摘要： PURPOSE:To simply clean the inside of tube and repair tube after constructing tubes as well as simplify the construction of tubes by a connector for double- layer tube consisting of an inner tube having a drin passage and an outer tube covering the inner tube, having an air passage between the inner and outer tubes. CONSTITUTION:The lower end of a double tube on the upstream side is connected with the upper end of double tube on the downstream side through a given interval by connecting the ends of the inner tubes 1 of these double tubes by inner couplers 3 and 5 which can be moved toward the axial direction of tube and can also be separated toward the diametral direction. The ends of the outer tubes can also be connected by using outer couplers 4 and 6 which can be moved toward the axial direction of tube and can also be separated to the diametral direction.

摘要： PURPOSE:To facilitate connection of a double layer pipe and cleaning of the inside of an inner pipe through which a drain flows. CONSTITUTION:A branch pipe 34 is projectingly arranged so as to surround a through hole 33 arranged on a side wall of an inner joint 3, while the tip of the branch pipe 34 is faced to a through hole 42 arranged on the side wall of an outer joint 4. A cap 5 is fitted in the branch pipe 34 freely removably, while a flange 52 of the cap 5 is fixed on the side wall of the outer joint 4 by means of a spring member 6 such as a machine screw. In this way, a double layer pipe can be easily connected, while cleaning work for the inner pipe inside is facilitated.

摘要： PURPOSE:To prevent the inside of a pipe from turning to negative pressure and make drainage so as to flow in the pipe so smoothly by installing an inlet valve in a proper spot in a pipeline of a horizontally laid pipe, a drainage vertical pipe or the like. CONSTITUTION:Drainage equipment 1 and collecting joints at respective floors are connected by each horizontally laid pipe 2, while the upstream part and the downstream part of a drainage vertical pipe 4 are connected to top and bottom of the collecting joint 3 and drainage flowing into from the horizontally laid pipe 2 is made to flow down in this drainage vertical pipe 4 as turning it along an inner wall of the collecting joint 3. Then, an inlet valve A is installed in a proper spot in a pipeline of the horizontally laid pipe 2, the drainage vertical pipe 4 or the like. Therefore, since air flows into the inside of the pipe and thereby drainage flows smoothly thereinto, any solid matter as muck or the like will in no case stay in the inside of the pipe.

摘要： PURPOSE:To provide a drainage joint capable of turning drain flowing in from a cross main pipe while dropping the drain smoothly into the downstream part riser. CONSTITUTION:The lower part of a cylindrical joint body 1 is diametrally contracted to the funnel-like form and provided with a connection part 2 connected to a drain riser, while the upper part is provided with a vent port 31. Also, the joint body is provided on the inner peripheral wall with a turning groove 11 bulging in the outer peripheral direction, and a joint pipe 4 is connected to the turning groove 11 from the tangential direction to communicate thereto. Thus, drain flowing in from a cross main pipe can be smoothly dropped into the downstream riser.

摘要： PURPOSE:To provide a collective drainage joint by which drain water falling from a vertical drain pipe and drain water flowing in from a horizontal pipe are joined smoothly to fall. CONSTITUTION:The upper part of a cylindrical joint main body 30 is contracted in the diameter, and an upper joint 31a to be connected to a vertical drain pipe 4 on the upper stream side, is provided, while a lower joint 31b to be connected to the vertical drain pipe 4 on the lower stream side is provided by contracting the lower part of the joint main body 30 in the diameter into a funnel shape. A cylindrical body 33 hung in the joint main body 30 from the upper joint 31a is provided, and the cylindrical body 33 is formed into a tapered form contracted in the diameter from above to downward. A branch joint 32 to be connected to a horizontal pipe 2 from the tangential direction is provided on the side wall of the joint main body 30. Since drained water fallen from the vertical pipe on the upper stream side and drained water flowing in from the horizontal pipe are smoothly joined to fall, no failure in passing water is generated.
