It is high and disconnect the connection of flushing pipe and third connector, avoid the spilling of liquid；
4, between the second connector and screw type fittings to be rotatably connected, by screw type fittings and nutrient canal or drainage bottle
When mutually screwing, three-way connection and nutrient canal or drainage bottle can be motionless, only rotate screw type fittings, avoid nutrient canal pipe
Body due to frequently occurring distortion and winding caused by service life the case where being shortened, and sealing structure can prevent screw type fittings
The exudation of liquid between the second connector；
5, the flange of second connector one end is located in the annular groove of screw type fittings inner sidewall, facilitates screw type fittings phase
Second connector is rotated, and is located at flange side as the first sealing ring of sealing structure, when nutrient canal or drainage bottle screw in spiral shell
When in rotating connector, nutrient canal or drainage bottle top are pressed in the flange top of the second connector, make between flange and screw type fittings
The first sealing ring be extruded, the liquid entered in screw type fittings at this time also just can not gap between flange and groove seep
Out, reach good sealing effect；
6, when fastening joint is Tapered nipple, nutrient canal or drainage bottle are that one end of tapered structure is insertion end, this is inserted
The tapered side wall for entering end is equipped with annular projection, when the insertion end of nutrient canal or drainage bottle stretches in Tapered nipple, insertion end
On protrusion be caught in the cambered surface groove of Tapered nipple inner sidewall, and the second sealing ring by protrusion and cambered surface groove mutual extrusion
Ring packing is formed, liquid is avoided to ooze out；In addition, elastic rubber pad on Tapered nipple inner sidewall also with nutrient canal or drainage bottle
The contact of insertion end lateral wall, increases frictional force, and it is unexpected from cone to further avoid insertion end when nutrient canal or drainage bottle are pullled
Abjection, improves the stability of connection in type joint.
