Document Type and Number:
Japanese Patent JP6939194
Kind Code:
B2
Abstract:
To provide a resin elbow joint capable of suppressing a reduction in flow rate of fluid flowing in a fluid supply cock at a terminal of a fluid supply system when the number of resin elbow joints provided in the fluid supply system is increased.SOLUTION: A resin elbow joint 1 comprises a resin joint body 5 having an L-shaped corner part 4 that connects a first straight part 2 and a second straight part 3 and that is formed integrally with them. The first straight part 2 of the joint body 5 is provided with a first lock mechanism 7 that prevents a pipe 6 connected to the first straight part 2 from pulling off. The second straight part 3 is provided with a second lock mechanism 9 that prevents a pipe 8 connected to the first straight part 3 from pulling off. For the resin elbow joint 1, an equivalent pipe length is less than 1.0 m, and more specifically less than 0.8 m.SELECTED DRAWING: Figure 3
