Abstract
The invention relates to a high-pressure rotary joint, which belongs to the technical field of the sealing device and mainly comprises a front case body, a liquid-feeding case body, a middle case body, a liquid-discharging case body and a rear case body which are fixedly combined into a whole; the pad type combination sealing rings are respectively arranged between the parts, a front bearing is arranged in the front case body and a rear bearing is arranged in the rear case body; an outer tube is arranged in the combination device and supports the front bearing and the rear bearing; an O-shaped sealing ring is arranged on an internal tube, which is connected with the inner sealing thread of the outer tube by the outer sealing thread; the internal thread on the liquid-feeding case body and the liquid-discharging case body are connected with a stationary pipe. The invention is simple and reasonable in structure and is convenient to install and maintain; the combination type case body is easy to manufacture and easy to assemble; the pad type combination sealing ring is wear-resistant and the higher the working pressure is, the better the sealing property will be; the sealing surface of the rotation shaft is coated with a high-hardness non-metal material, the fineness is very high, which considerably improves the wearing resistance of the sealing element and prolongs the service life; also the disassembly is convenient, the concentricity is good and the rotary moment is small.
Description
Technical field
The present invention relates to a kind of high pressure swivel joint, specifically be used for flowing medium and be input to the connection sealed member of rotating equipment, belong to the seal arrangement technical field from static pipeline.
Background technique
To be flowing medium (oil, steam, water, gas etc.) be input to connection sealed member the rotating equipment from static pipeline with swivel joint, is the seal arrangement that solves run, drip, leak, energy saving, protection environment, improves working conditions.The swivel joint housing of normally used high pressure (GYL type) series mainly adopts overall structure, in whole housing outer tube is installed, pipe in installing in the outer tube, and outer tube is supported by front and back bearings, on the interior pipe seal ring is housed.The swivel joint of this kind structure is when rotating operation, and latus rectum and pressure are subjected to restriction to a certain degree, and Sealing leakage easy to wear, so working life is very short, can only use continuously one month, even just need in a week to change.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of high pressure swivel joint is provided, can improve sealing load and working pressure, Sealing is difficult for wear and leakage, and can increase the service life.
Main solution of the present invention is achieved in that
The present invention mainly adopts front case, the feed liquor housing, middle shell, fluid housing and rear case are fixed into the combination housing, between front case and feed liquor housing, cushion combined seal ring before installing respectively between feed liquor housing and the middle shell, between middle shell and the fluid housing, back cushion combined seal ring is installed respectively between fluid housing and the rear case, fore bearing is installed in the front case, rear bearing is installed in the rear case, outer tube is loaded in the combination housing and is supported in fore bearing and rear bearing, sealing O type circle is housed on the interior pipe, interior pipe is connected with outer seal of tube internal thread with the sealing outside thread, and the feed liquor housing is connected with static pipeline with internal thread on the fluid housing.
Sealing surfaces is provided with wearing layer in the outer tube of the present invention.
Sealing O type circle of the present invention is made as 2.
Compared with the prior art the present invention has the following advantages:
Rotary joint structure of the present invention is simple, reasonable, installation, maintenance is convenient; Combined shell is easy to manufacture, assembling is simple; Cushion combined seal ring material wear-resistant, working pressure are high more, and sealability is good more; Rotation axis seal face spraying high hardness nonmetallic material, degree of finish is high, has improved the wear resistance of fit seal greatly, thereby has prolonged working life; Combination housing two ends are equipped with the bearing that varies in size, convenient disassembly, and coaxality is good, and running torque is little.
Description of drawings
Fig. 1 is a structural front view of the present invention.
Fig. 2 is a structure left view of the present invention.
