Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing and example.

[0014] The front end of the valve core 08 is fastened to one side of the trunnion 13 of the rotary extruder by bolts, and the direction of the oil outlet 12 is perpendicular to the rotation center line of the extruder, so that the hydraulic pipeline can rotate together with the main working cylinder of the rotary extruder.

[0015] The valve body 01 is fastened on the fixed bracket 09 by bolts to prevent the valve body 01 from rotating. The spool 08 is provided with a diameter 15 vertically connected to each other, the diameter of the diameter 15 can reach 250mm, and the rated pressure can reach 5Mpa. The area of ​​the cross-section of the internal diameter 15 of the spool 08 is equal to the sum of the areas of the two oil inlets 11 of the spool 08, so that the hydraulic oil enters the spool 08 smoothly and avoids damping and impact. The rear portion of the spo...

Abstract

The invention discloses a hydraulic low-pressure large drift diameter rotating joint. The rotating joint is characterized in that a mutually and vertically communicated drift diameter is formed in a valve core, wherein the front end of the valve core is provided with a radial oil outlet, and the middle part is provided with two oil inlet holes; the sectional area of the drift diameter of the valve core is equal to the sum of the sectional areas of the two oil inlet holes symmetrically formed in the two sides of the middle part of the valve core; the valve body is provided with an oil cavity with an oil inlet; a plug is fastened to the tail end of the valve body through a screw; the radial oil outlet formed in the front end of the valve core can form a random included angle with the vertical direction according to the actual condition of the mounting site. The rotating joint has the technical effects that small size and large drift diameter are realized, the drift diameter can reach up to 250 mm, the area of the section of the cavity of the valve core is equal to the sum of the areas of the two oil inlets of the valve core to avoid damping and impact phenomena, the direction of the oil outlet is perpendicular to the rotation central line of an extruder, a hydraulic pipeline can rotate together with a main working cylinder of the rotary extruder, and the oil inlet in the fixed end can be designed at the random angle with the vertical direction according to the actual condition of the mounting site.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment. Background technique [0002] Due to the structural characteristics of the rotary extruder, the whole machine needs to be rotated, so the hydraulic pipeline must be rotated to transmit hydraulic oil. At the same time, due to the high tonnage of the equipment and the large demand for hydraulic oil, the diameter of the pipeline needs to be made as large as possible. The existing rotary joint has a small diameter, and the oil inlet and outlet can only be transported coaxially, which cannot meet the needs of this working condition. Contents of the invention [0003] In order to realize the large-diameter rotary transmission function for hydraulic pressure, the present invention specially designs the following technical solutions for the rotary electrode extrusion machine: a low-pressure large-diameter rotary joint for hydraulic pressure. , the diameter of the diameter can reach 250mm....
