Description
Technical field
The utility model is related to wind-powered electricity generation lubrication technical fields, and in particular to a kind of filter of wind turbine lubrication belt unloading valve
Lid.During filter core superpressure applied to lubricated filter, excessively high pressure can be fallen with off-load, ensures the not damaged contaminated system of filter core.
Background technology
The lubricating oil of the filter device of wind-powered electricity generation lubricating system flows through filter core resistance increase and service life in low temperature and expires
Resistance increases when dregs block, and flow resistance increases to：During 4bar, pressure needs off-load to ensure that filter core is not damaged, causes to lubricate
Systemic contamination, while ensure that lubricating oil can also normally circulate；Therefore on filter core would generally one by-passing valve off-load of band, but filter core
It is that a kind of easily-consumed products are replaced every time, since unloading valve and filter core manufacture are integrated, can be wasted by abandoning together, not be inconsistent compound energy-saving type
Social desirability.
Utility model content
The purpose of this utility model is that in view of the above-mentioned problems existing in the prior art, provide a kind of wind turbine lubrication belt off-load
The strainer cover of valve.
To achieve these goals, the utility model uses following technical measures：
Including strainer cover, oil suction chamber is provided in the middle part of strainer cover for a kind of strainer cover of wind turbine lubrication belt unloading valve
Body, off-load valve body one end run through oil inlet cavity, fuel feed hole are offered on oil inlet cavity, and the off-load valve body other end is connected with filter core,
The sliding cavity of perforation off-load valve body both ends of the surface is provided in unloading valve body, sliding cavity is provided with gear close to one end of oil inlet cavity
Ring, the sliding cavity other end are provided with installing plate, and the off-load spool that can be moved back and forth along sliding cavity, unloading valve are provided in sliding cavity
Core includes catch and the connecting pole being arranged in the middle part of catch, spring one end are set on connecting pole, the spring other end and installation
Plate offsets, and the outer diameter of catch is adapted to the internal diameter of sliding cavity, and the outer diameter of catch is more than the internal diameter of baffle ring, and catch is in the effect of spring
The part that lower and baffle ring offsets offers recirculation hole, and delivery outlet is offered on installing plate.
The utility model has the advantages that compared with the prior art：
1st, strainer cover and off-load valve body cleverly Integrated design, multiple fuel feed holes can be set to be converged on oil inlet cavity
Always, the narrow and small underfed of installation site inside strainer cover is solved the problems, such as；
2nd, it is simple in structure, it is reusable, it reduces and replaces the cost of filter core, meets energy conservation and environmental protection；
3rd, removing, loading onto action for off-load valve body is completed during normally opening, shut strainer cover, is prevented
Only maloperation is by the anti-loaded mistake in off-load valve body direction.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Fig. 1~5, a kind of strainer cover of wind turbine lubrication belt unloading valve, including strainer cover 1, in strainer cover 1
Portion is provided with oil inlet cavity 8, and 2 one end of off-load valve body runs through oil inlet cavity 8, fuel feed hole 13, unloading valve are offered on oil inlet cavity 8
2 other end of body is connected with filter core 7, and the sliding cavity 9 of 2 both ends of the surface of perforation off-load valve body is provided in off-load valve body 2, and sliding cavity 9 leans on
One end of nearly oil inlet cavity 8 is provided with baffle ring 10, and 9 other end of sliding cavity is provided with installing plate 5, and being provided in sliding cavity 9 can edge
The off-load spool 3 that sliding cavity 9 moves back and forth, off-load spool 3 include catch 301 and are arranged on the connecting pole at 301 middle part of catch
302,4 one end of spring is set on connecting pole 302, and 4 other end of spring offsets with installing plate 5, the outer diameter and sliding cavity of catch 301
9 internal diameter adaptation, the outer diameter of catch 301 are more than the internal diameter of baffle ring 10, and catch 301 offsets under the action of spring 4 with baffle ring 10
Part offer recirculation hole 11, delivery outlet 12 is offered on installing plate 5.
As shown in figure 3, when in use, strainer cover 1 is covered to the end for being located at lubricated filter, by the end of off-load valve body 2
Portion's card is set in the filter core 7 in lubricated filter, bears that pressure is smaller, and lubricating oil applies through fuel feed hole 13 outside filter core 7
When pressure on to the catch 301 of off-load spool 3 is less than the elastic force that spring 4 extends, spring 4 is by the catch 301 of off-load spool 3
Outer is pressed on baffle ring 10, and baffle ring 10 blocks recirculation hole 11, and lubricating oil will not enter sliding cavity 9 by recirculation hole.
