Angle rotary connector capable of entering and exiting same channel by plurality of channels

Abstract

The invention discloses an angle rotary connector capable of entering and exiting the same channel by a plurality of channels. The channels are arranged at the outer end of a lower shell body; 4-32 channels are arranged; each channel is internally provided with an annular sealing part, a first O-shaped ring, a spring cushion and a spring in sequence; a rotary shaft is arranged in an upper shell body; a star-shaped sealing ring is arranged under a first bearing between the rotary shaft and the lower shell body; a common channel is arranged on one side of the upper shell body; an annular groove is formed in the horizontal plane of the lower part of the rotary shaft; the annular groove corresponds to the common channel in the vertical direction; a second O-shaped ring is arranged on one side of the annular groove and a third O-shaped ring is arranged on the other side of the annular groove; the annular groove of the rotary shaft is internally provided with a rotary shaft channel and the rotary shaft channel corresponds to the channel; a star-shaped ring is arranged between the rotary shaft above a second bearing and the shell body; a key slot is formed in the outer end of the rotary shaft; and the upper shell body and the lower shell body are fixedly connected through a bolt. The angle rotary connector is simple in structure, is supported by the double bearings and is flexible to rotate and the torque is alleviated. The sealing effect is ensured and the service life is prolonged.

Description

technical field [0001] The invention belongs to a rotary joint, in particular to an angle rotary joint in which multiple channels enter and exit the same channel. Background technique [0002] In the chemical industry and medical laboratory equipment, when multiple media enter the same container, such as chemical tanks, reaction kettles, and laboratory chambers, several pipelines and solenoid valves or electric valves are required to control the import and export, which wastes material and financial resources and is not conducive to automation control. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides an angle rotary joint with multiple channels entering and exiting the same channel. The angle rotary joint with multiple channels entering and exiting the same channel has a simple structure and a servo motor cooperates with the angle rotation to complete the conversion of entering or exiting various...
