Abstract
The invention discloses a rotary motion valve mounting structure which comprises a valve rod and a mounting bracket, wherein a mounting base plate vertical to the axial direction of the valve rod is arranged on the mounting bracket; a mounting hole of the valve rod is formed in the mounting base plate; the valve rod penetrates through the mounting hole of the mounting base plate; an upper thrust ball bearing locked on the mounting base plate through an upper self-locking nut is mounted on the valve rod on the upper side of the mounting base plate in a sleeving manner; and a lower thrust ball bearing locked on the mounting base plate through a lower self-locking nut is mounted on the valve rod on the lower side of the mounting base plate in a sleeving manner. According to the rotary motion valve mounting structure, the valve rod of a rotary motion valve is axially mounted and located on the mounting bracket effectively and reliably, and the mounting and location effectively reduce the valve trim gravity received by the valve rod and a valve seat, so that the opening and closing actions of the rotary motion valve are easy, the abrasion between a valve core and the valve seat is greatly alleviated, and the axial displacement phenomenon of the valve rod is avoided; and, the structural characteristics ensure that the rotary motion valve is stable in operation, good in sealing performance and long in service lifetime.
Description
Technical field
The present invention relates to rotary motion valve, specifically a kind of rotary motion valve mounting structure.
Background technique
Rotary motion valve is primarily of compositions such as valve seat, spool and valve rods, spool is assemblied in valve seat, valve rod be connected with spool and extend valve seat carry out installation fix, under the effect of valve rod, spool follows the angle spinning movement that valve rod is done perpendicular to valve rod together, realizes conducting and cut-out with this to the medium channel on valve seat.
Can clearly be found out by the structural characteristics of rotary motion valve, the trim weight comprising spool acts directly on valve rod, simultaneously and also acts on valve seat, this just causes the action that opens and closes of rotary motion valve to require great effort, reliable not, but also the wearing and tearing that can aggravate between spool and valve seat, stable not, working life is short; In addition, the trim of conventional angular stroke valve, under the pressure surge of medium, vibrates in valve seat, and then makes valve rod occur upper and lower play phenomenon, and this will have a strong impact on the sealability of rotary motion valve.
In view of this, the rotary motion valve mounting structure of various optimization has been there is in industry, disclosed " a kind of angle journey valve support " (publication number: CN200975538 of such as Chinese patent literature, publication date: on November 14th, 2007), " angular travel valve mounting rack " (publication number: CN2653259, publication date: on November 3rd, 2004) etc., although these technology compare traditional rotary motion valve, the installation of valve rod on support being achieved rotary motion valve by bearing structure is fixed, alleviate the direct effect of trim gravity on valve seat, and the play phenomenon of valve rod.But, the unreasonable structure that these technology are arranged on mounting bracket due to bearing, still there is stable not and reliable technical problem, this is because: 1. the contact friction that locking nut set on the valve rod at bearing place can be long-term with mounting bracket, in the course of time can there is serious wear phenomenon, cause loosening the spacing of bearing; 2. the locking mechanism of locking nut on valve rod can damage the structural stress of valve rod, and then affects the structural strength of valve rod.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned the deficiencies in the prior art, one is provided to be formed in the axial direction effectively valve rod and reliably location to be installed, and this installation and positioning structure can be stablized, firmly, lastingly, the simultaneously impregnable rotary motion valve mounting structure of stem structure intensity.
The technical solution adopted in the present invention is: a kind of rotary motion valve mounting structure, comprise valve rod and mounting bracket, described mounting bracket have the installation base plate perpendicular with the axis of valve rod, this installation base plate has the mounting hole of valve rod, described valve rod penetrates the mounting hole of installation base plate, valve rod on the upside of installation base plate is set with the lifting force ball bearing of being locked on installation base plate by upper self-locking nut, the valve rod on the downside of installation base plate is set with the lower thrust ball bearing of being locked on installation base plate by lower self-locking nut.
Preferably, in the mounting hole of described installation base plate, be provided with radial ball bearing, valve rod in radial ball bearing axially across.Further, the inner ring of described radial ball bearing is connected with valve rod threadably, outer ring is connected with the mounting hole hole wall of installation base plate threadably.
