The positioning column is inserted into one of the positioning holes, and the tail of the positioning column has a spring support, and the rotary joint has a ring groove on the peripheral wall adjacent the water end panel, wherein a seal is embedded; of course, the seal can also be fixed. On the side of the elbow in the rotary joint and the elbow of the elbow.

The lower portion of the rotary joint angle controller has an outgoing tube, and the upper portion has an outer ring wall loosely inserted on the proch and can rotate each other, and a partition is provided in the middle of the ring wall and in the center of the separator. A through hole is provided, the head of the screw is relaxed through the central via and the tapered phase threaded, and the end surface of the annular wall hydraulic ferrule Manufacturers is equal to the tail flange of the screw.

The rotary joint for the sprinkler is characterized in that the rotary tube joint, elbow, angle controller; the water end of the rotary tube joint is inserted into the inlet end of the elbow and connected to each other. The inlet end of the rotary tube joint is the inlet end of the entire rotary joint; the angle controller is combined by the upper and lower parts and can rotate each other,

and its inlet end is located at the rear end of the lower portion of the angle controller, and Fixed and communicated with the outlet end of the elbow, the water end is located at the front end of the upper portion of the angle controller, and the rotation shaft of the upper and lower portions of the angle controller is perpendicular to the plane of the bend axis of the elbow.

Such a rotary joint provides a proximity 360 & deg on the lateral plane between the rotary tube joint and the elbow, the two binds, so that the angle controller is secured to the inlet end of the pipe joint and the rod tube connection.
