Embodiment 1

[0027] One kind of automatic anti-drip nozzle large flow, comprising a tube fitting 1, the top block 2, the sealing shaft 3, a spring 4, the cavity 5, the housing 6, 7, 8 and the stopper ring 11, inner housing 6 is provided with a sealing block cavity 5, the inner cavity 5 is provided with a shaft seal 3, the upper end of the shaft 3 is provided with a sealing top block 2, the bottom end of the joint pipe 1 is smaller than the diameter of the inner wall of the upper end of the outer wall diameter of the top block 2, and the bottom end of the joint pipe 1 and the inner wall of the top block 2 bonded to the upper end of the exterior wall, the bottom wall of the housing 6 disposed symmetrically distributed stopper 11, stopper 11 constituting the outer wall of the through groove between the side inner wall 9 of the cavity 5, the through-flow channel 9 for lubricating oil, and sealing stopper 11 for limiting the outer wall of the shaft 3, the seal holding shaft 3 a vertical state, to p...

Embodiment 2

[0030] When filling starts, the joint pipe 1 is connected to the filler pipe, and the valve opening of the filler pipe, anti-drip nozzle above the pre-stage pressure is greater than 1.5bar, top block 2 and the oil push spring 4 is moved downward, while pushing the top sealing block 2 shaft 3 is moved downward, top block 2 and the lower end of a pipe joint gap, so that the lubricating oil through the gap into the cavity 5, while the driven shaft 3 sealing the sealing block 7 is moved downwardly, the lower end of the sealing block 6 when the housing opening 7 after the gap, the lubricating oil can block 7 and the lower end 6 of the housing discharge opening, automatic drip resistant nozzle opening via the through groove 9 and the seal.

Embodiment 3

[0032] After completion of oiling, tubing injection valve is closed, so that the pressure is reduced, when less than 1.5bar, a spring 4 pushing the reset rising top block 2, the top block 2 and the joint pipe 1 is bonded to the lower end of the passage block, and the top 2 block to drive shaft 3 by sealing the sealing block 7 rises, the sealing ring 8 and the block 7 to block the gap between the lower end wall of the housing 6, the top block 2 and the sealing block synchronization enclosed cavity 7 ends 5, reaching anti-drip nozzle automatically closes the effect of non-human intervention to achieve automatic opening and closing of the anti-drip effect.

[0033] Working principle: When filling starts, the joint pipe 1 is connected to the filler pipe, and the valve opening of the filler pipe, anti-drip nozzle above the pre-stage pressure is greater than 1.5bar, top block 2 and the oil pushed downward movement of the spring 4, the top block 2 while promoting sealed shaft 3 is moved ...

Abstract

The invention discloses a large-flow automatic drip-proof nozzle. The nozzle comprises a connector pipe, a top block, a sealing shaft, a spring, a cavity, a shell, a sealing block, a sealing ring and limiting blocks, the cavity is formed in the shell, the sealing shaft is arranged in the cavity, the top block is arranged at the upper end of the sealing shaft, the limiting blocks are symmetrically distributed on the inner wall of the bottom end of the shell, the lower end of the sealing shaft penetrates through the interiors of the two limiting blocks, the lower end of the sealing shaft is connected with the sealing block, symmetrically-distributed embedding grooves are formed in the outer wall of the sealing block, the connector pipe is rotationally inserted into the inner wall of the upper end of the shell, a clamping groove is formed in the outer wall of the lower end of a top block, and the outer wall of the sealing shaft is sleeved with the spring. The drip-proof nozzle can achieve the automatic anti-leakage effect, can meet the requirement for filling of lubricating oil with the flow larger than 20 L / min and automatic opening and closing when the flow of the lubricating oil is smaller than 100 L / min, achieves automatic opening and closing of anti-leakage without human intervention, and is simple in structure, reliable in performance and wide in circulation amount application range.

Description

Technical field [0001] The present invention relates to the technical field of anti-drip nozzle, in particular to a large flow rate automatic anti-drip nozzle. Background technique [0002] Anti-drip nozzle is a component of the lubricating oil in the quantitative filling gun to achieve complete filling automatic drip put the gun, which belongs to a part of the lubricating oil quantitative filling gun. When the filling is completed the filling apparatus, the injection valve is closed competent way, filling gun end of the pressure reduction, anti-drip nozzle automatically seals the injection port gun oil passage, the oil does not occur in the process of moving the gun operator takes drip fluid. [0003] There are two conventional drip, GRACO standard is the use of small anti-drip nozzle when the injection speed, the other is using a large injection speed when the hand or the manual control valve with anti-drip nozzle, require manual rotation to open or sealed live. [0004] In sum...
