Abstract
The utility model discloses a rotary motion valve bracket, which composes a valve rod subassembly support mechanism; wherein the support mechanism comprises a bearing, a screw sleeve lock nut and a bearing inner ring lock nut and a bearing outer ring lock nut; and the screw sleeve is composed of an inner and an outer screws, wherein the inner screw is matched with the valve rod screw; and the bearing is arranged on the bracket, while the outer ring is matched with a foundation bracket, whereas the inner ring is matched with the screw sleeve; and the bearing outer ring lock nut is matched with the bracket screw, while the bearing inner ring lock screw is matched with the external screw of the screw sleeve; and the screw sleeve lock nut is matched with the valve rod screw; and the rotary motion valve bracket is composed of a foundation bracket and a heat insulation bracket. The utility model has the beneficial effects of that: the gravity bearing of the valve rod piece, the axial direction alternative pulsing load absorption produced by the valve inside pressure vibration, and the axial direction load of the driving gear and the axial direction adjustment of the valve rod subassembly are solved, accordingly improving the heat radiation and conduction of the cold and heat sources towards the driving gear, leaving no vibration inside of the valve and reducing abrasion, as well as greatly promoting the service life of the part.
Description
Technical field
The utility model relates to angular stroke control valve, relates in particular to the mounting bracket of this modulating valve, is used for supporting driving device and valve rod assembly.
Background technique
The service behaviour of sealing pair in the valve reduces valve rod assembly in the valve, the inordinate wear of sealing pair because the gravity cause causes.When the valve internal pressure is vibrated, drive unit is produced an axial alternating shock load, make above-mentioned phenomenon aggravation, the drive unit life-span is reduced.
For camflex valve, butterfly valve isogonism stroke valve class,, must guarantee axially accurately location and locking of valve rod assembly in order to ensure the service behaviour and the life-span of sealing pair, drive unit in the valve.
In addition, valve is worked under various environmental conditionss, its fed sheet of a media temperature is in-60 ℃ of-600 ℃ of scopes, and the operating temperature that drive unit allows is-30 ℃-70 ℃, when carrying high temperature or cryogenic media, its thermal radiation, transmission of heat will make the ambient temperature of drive unit exceed the scope of permitted value, reduce the performance and the working life of drive unit.
Existing " mouth " font, all unresolved the problems referred to above of " day " font support that are widely used in stroke valve class.
The model utility content
The purpose of this utility model, providing a kind of valve rod can axial displacement, the good rotary motion valve mounting bracket of heat radiation, and its technical solution is:
A kind of rotary motion valve support has the valve rod assembly support mechanism, and this support mechanism comprises bearing, thread bush, bearing outer ring locking nut, bearing inner race locking nut, thread bush locking nut; Described thread bush has internal and external screw thread, and its internal thread cooperates with the threaded stem section; Described bearing is arranged on the described support, and its outer ring cooperates with support, and its inner ring cooperates with thread bush; Described bearing outer ring locking nut and described support screw-thread fit, described bearing inner race locking nut cooperates with the outside thread of described thread bush; Described thread bush locking nut cooperates with threaded stem.
Described rotary motion valve support is formed by base rack and heat insulation holder combination, and described heat insulation support is fixed on the end face of base rack, and described valve rod assembly support mechanism is arranged on the base rack.
The outside of described heat insulation support is provided with radiating fin.
The utility model has the advantages that: location because valve rod assembly is locked, axial displacement can not take place in valve rod, the axial alternating shock load that the gravity of valve rod assembly, pressure oscillation produce is born by base rack by bearing, thereby the wearing and tearing that alleviate sealing pair improve sealing effect.The heat insulation support of combination varying number can reduce thermal radiation, the transmission of heat of heat (cold) source to drive unit effectively, and its ambient temperature is met the requirements, and prolongs the life-span of drive unit.
Description of drawings
Figure one is the base rack structure (normal temperature condition is used down) of the new shape of this practicality;
Figure two is combined heat insulated supporting structures (capable of being combined a plurality of) of the new shape of this practicality;
Figure three is a kind of forms (radiating fin is horizontally disposed with) of heat insulation support;
Figure four is another kind of forms (radiating fin vertically is provided with) of heat insulation support.
Embodiment
Describe in detail below in conjunction with accompanying drawing.
Referring to figure one: bearing 4 is housed on the base rack 2, and its outer ring cooperates with support 2, and its inner ring cooperates with thread bush 3.With bearing outer ring locking nut 5 and bearing inner race locking nut 6 bearing 4 is compressed, wherein, bearing outer ring locking nut 5 is and support 2 screw-thread fit that bearing inner race locking nut 6 is to cooperate with the outside thread of thread bush 3.Loosening in order to prevent inner ring locking nut 6, this nut can adopt double nut.The thread section of valve rod 8 is positioned at thread bush 3, and the two is threaded.Thread bush locking nut 7 cooperates with the thread section of valve rod 8, is positioned at the lower end of thread bush 3, and thread bush 3 is compressed, and like this, valve rod 8 just is positioned, and axial displacement can not take place.
When valve rod assembly 8 needs to do axially to adjust, thread bush locking nut 7 is unscrewed rotary bearing locking nut 6, driving thread bush 3 rotates synchronously, make it and axial relative displacement takes place for valve rod 8, move to the height and position that needs when valve rod 8 after, again thread bush locking nut 7 is screwed.
Referring to figure two: for the valve that uses under the distinct temperature operating mode, can install heat insulation support 1 additional on base rack 2, installation number is just determined according to temperature, the operating mode of ultralow temperature, high temperature, and available a plurality of heat insulation supports 1 make up, to meet the demands.
Referring to figure three, figure four: two outer side surfaces of heat insulation support 1 are provided with radiating fin.The direction of radiating fin can be substantially horizontal (figure three), also can be vertical direction (figure four).
Use the said structure mode can effectively solve the moving support problem of valve rod assembly; Solve the axial alternating shock load absorption problem that the vibration of valve internal pressure produces; Solve the axial load problem of drive unit; Solve the axial adjustment problem of valve rod assembly, also improved thermal radiation, the heat conducting problem of cold ﹠ heat source to driving simultaneously, make friction in the valve, it is little to wear and tear, and improve working life greatly.
