Abstract
The present disclosure relates to an oil barrel outlet nozzle, which comprises a fixed pipe, a closing mechanism slidably arranged therein, and an oil outlet pipe, which are connected through a rigid linkage structure. The linkage structure responds to the sliding of the oil outlet pipe to drive the movement of the closing mechanism while isolating the motion transfer between the two, ensuring that the sealing interface between the closing mechanism and the fixed pipe remains independent of wear on the oil outlet pipe. Through the O-ring seal between a sealing plate and a protrusion and the synergistic action of a pneumatic balancing device and a limiting mechanism, the sealing reliability and service life are significantly improved.
Claims11
An oil barrel outlet nozzle, comprising:
- a fixed pipe, comprising an oil inlet and an oil discharge port;
- and
- a closing mechanism arranged on the oil inlet of the fixed pipe, with a first sealing member at a bottom thereof for opening and closing an oil passage of the oil inlet;
- and
- an oil outlet pipe slidably inserted into the oil discharge port, with a second sealing member on an outer wall thereof for sealing a gap between the oil outlet pipe and the fixed pipe;
- and
- a linkage structure arranged between the oil outlet pipe and the closing mechanism;
- wherein the first sealing member and the second sealing member are physically isolated and operate independently;
- and
- the linkage structure converts an axial displacement of the oil outlet pipe into an opening/closing motion of the closing mechanism.
