Novel rotary anti-swing valve

Abstract

The invention discloses a novel rotary anti-swing valve which includes a rotary motor, a sealing mechanism, a sealing cover, mounting holes, an oil inlet, a protection mechanism, a lubrication mechanism, a connecting rod, a slide plate, an oil passage, a sponge pad, a fixed seat, a pressure spring and an anti-sway mechanism. The novel rotary anti-swing valve has the beneficial effects that in theinstalling process, the four mounting holes of the rotary motor are aligned with double-screw bolts of a body of an excavator, when the four double-screw bolts on the excavator abut against the mounting holes, abutting of the slide plate inside the mounting holes is achieved, the connecting rod further drives the slide plate to move in the direction of the pressure spring, the slide plate can further extrude the sponge pad, lubricating oil on the surface of the sponge pad moves towards the interior of the oil passage, when the slide plate is separated from one end of the oil passage, the lubricating oil is extruded to the positions between the mounting holes and the double-screw bolts, lubrication of the double-screw bolts is achieved, influences of rusting of the double-screw bolts duringwater inflow of the excavator on disassembling are avoided, the pressure spring resets to achieve resetting of the slide plate by the connecting rod during disassembling, the double-screw bolts on the excavator are conveniently disassembled, and overhauling is facilitated.

Description

technical field [0001] The invention relates to a control valve, in particular to a novel rotary anti-swing valve, which belongs to the technical field of control valves. Background technique [0002] At present, during the braking process of the hydraulic slewing motor on the excavator, the pressure shock and pressure fluctuation caused by the inertia will cause the hydraulic motor to act alternately forward and reverse instantaneously. This instantaneous forward and reverse rotation will cause the hydraulic system to fluctuate, so Installing a new type of rotary anti-swing valve on the excavator can slow down the fluctuation of the hydraulic system caused by the anti-alternating rotation. [0003] However, at present, the control valve body is directly fixed on the studs of the excavator body during installation. Due to the uncertain working environment of the excavator, the bolts that fix the control valve rust after being exposed to water, which leads to problems when th...

Problems solved by technology

[0003] However, at present, the control valve body is directly fixed on the studs of the excavator body during installation. Due to the uncertain working environment of the excavator, the bolts that fix the control valve rust after being exposed to water, which leads to problems when the control valve is overhauled. Difficult to disassemble, due to the small gap between the bottom of the new swing anti-swing valve and the studs of the excavator body, it is difficult to release the lubricating oil, and it is difficult to disassemble
