Abstract
The utility model relates to a duplex rotary joint for pipes used for transmitting pressurized fluid to a rotary mechanism, which is composed of a rotator, a core pipe, etc., wherein, a central line of the core pipe is overlapped with a central line of the rotary joint, a hollow cavity used as a fluid circulation loop is arranged between the central line of the core pipe and the rotator, and the core pipe and a sliding bearing are in the sealing contact. When the utility model is used, the rotator and the core pipe are connected with a rotary mechanism and follow with the rotary mechanism to rotate, a casing is static, and the fluid is transmitted to the rotary mechanism from an inlet through the core pipe and is exhausted from an outlet through the hollow cavity after the circulation of the fluid is finished. The problem of simultaneous transmitting and exhausting fluid by one pipe joint is solved by the utility model, and the utility model has the advantages of long service life, good reversibility, etc.
Description
The utility model is the two-way swivel joint, relates to a kind of utensil to rotating mechanism transmission pressure fluid.
In industrial processes, the various circulatory systems such as cooling water are common.In order continuously to import and discharge fluid, static inlet duct and outer pipe are connected with rotating machinery to rotating machinery.In this case, a single channel swivel joint respectively being installed can meet the demands at the entrance and exit place.
Chinese patent CN88209856 is exactly this class single channel swivel joint, and it is made up of sleeve joint and core pipe joint.Between sleeve joint and core pipe joint, groove is arranged, is wherein loading ball, the two both can be rotated relatively, again can retainer shaft to connection.On the fitting surface of sleeve joint and core pipe joint, seal ring is housed, can prevents that pressure fluid from leaking.This kind return bend joint has good sealing property, turning quality and axial bearing capacity.But carry out simultaneously with a swivel joint in rotating mechanism one side under the situation of the input of fluid and discharge, this return bend joint is just inapplicable.
The purpose of this utility model is exactly in order to overcome the deficiency that above-mentioned return bend joint exists, designed a kind of can be to the rotating mechanism two-way swivel joint of transmitting two paths pressure fluid simultaneously.
The purpose of this utility model realizes in the following manner:
The two-way swivel joint is made up of housing (1), rotor (2), core pipe (3), ball (4), Sealing (5), sliding bearing (6), inlet elbow (7), gland (8), outlet (9) etc.In swivel joint, be provided with core pipe (3), the center line of core pipe (3) and the central lines of swivel joint; One end of core pipe (3) is overhanging, is connected with rotating mechanism, and in the sliding bearing (6) of the other end in housing (1) the axis central part through hole, the mouth of pipe communicates with inlet elbow (7) on the installation housing (1), has formed a new fluid passage.Between housing (1) and the rotor (2) common raceway is arranged, after ball (4) fills up raceway from load hole, seal, form two rolling bearings, realize relatively rotating and axially be connected between housing (1) and the rotor (2) with gland (8).Fitting surface between housing (1) and the rotor (2) adopts rubber and two kinds of materials of teflon to make with double seal (5) sealing, Sealing (5).The outer end of rotor (2) is provided with flange or close nipple, is convenient to link to each other with rotating mechanism.Sliding bearing (6) is supporting core pipe (3) one ends, and adopts contact seal with core pipe (3), with the entry and exit fluid isolation.Form a cavity between rotor (2) and the core pipe (3), the fluid after the circulation is flowed out by outlet (9) through cavity, forms circulation loop.During use, rotor (2) links to each other with rotating mechanism with core pipe (3), and rotates thereupon; Housing (1) is static, and links to each other with entry and exit pipes, and fluid just can enter rotating mechanism by core pipe (3), flows through cavity by exporting (9) discharge after finishing circulation.It has solved the input and the discharge problem of carrying out fluid in a side of rotating mechanism with a swivel joint simultaneously.
Fig. 1 is the structure sectional view of two-way swivel joint.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, in swivel joint, be provided with core pipe (3), the center line of core pipe (3) and the central lines of swivel joint.Core pipe (3) one ends are overhanging, are connected with rotating mechanism; In the sliding bearing (6) of the other end in housing (1) the axis central part through hole, the mouth of pipe communicates with inlet elbow (7) on being installed in housing (1).Between housing (1) and the rotor (2) common raceway is arranged, after ball (4) fills up raceway from load hole, seal, form two rolling bearings with gland (8).Double seal (5) sealing of making of fitting surface between housing (1) and the rotor (2) by rubber and two kinds of materials of teflon.The outer end of rotor (2) is provided with flange or close nipple, and links to each other with rotating mechanism.Sliding bearing (6) is supporting an end of core pipe (3), and adopts contact seal with core pipe (3), will go out, go into fluid and isolate.Form a cavity between rotor (2) and the core pipe (3), the fluid after the circulation is flowed out by outlet (9) through cavity, forms circulation loop.
The utility model has not only solved and has used a pipe joint can carry out simultaneously the defeated of fluid Enter and the discharge problem, but also have the strong and axle of long service life, good airproof performance, turning quality To advantages such as bearing capacity are big.
Claims (3)
1, a kind of two-way swivel joint, form by housing (1), rotor (2), core pipe (3), ball (4), Sealing (5), sliding bearing (6), inlet elbow (7), gland (8) etc., it is characterized in that being the center line of core pipe (3) and the central lines of swivel joint; Between core pipe (3) and the rotor (2) cavity as fluid circulation loop is arranged; Inlet and one export and are stored on the housing (1).
2, two-way swivel joint as claimed in claim 1 is characterized in that Sealing (5) made by rubber and two kinds of materials of poly-tetrem alkene.
3, two-way swivel joint as claimed in claim 1 is characterized in that adopting contact seal between sliding bearing (6) and the core pipe (3).
