Abstract
The utility model relates to an exhaust valve of a scroll compressor, which comprises a fixed scroll, a valve plate and a curved travel limiting plate for the valve plate. The fixed scroll includes an exhaustion plate and a scrolling ring. An exhaust hole is arranged in the center of the exhaustion plate. The scrolling ring is connected with one side of the exhaustion plate. After one end of the travel limiting plate for the valve plate and one end of the valve plate are overlapped, the valve plate is pressed against the outer margin of the other side of the exhaustion plate. The travel limiting plate for the valve plate, the valve plate and the exhaustion plate are connected together through a fastening bolt which sequentially penetrates through the travel limiting plate for the valve plate, the valve plate and the exhaustion plate. The other end of the travel limiting plate for the valve plate is an outward warped end far away from the exhaustion plate. The projection of the end on the exhaustion plate exceeds the exhaustion plate. The other end of the valve plate points to the center of the exhaust hole. The valve plate is long enough to enable the end to exceed the exhaust hole. An axial compensation clearance is left between the valve plate and the exhaust hole. During the operation of the valve, in virtue of the block-up effect of the lubricating oil film in the central area of the other side of the exhaustion plate, the service life of the valve plate and the air seal between the valve plate and the exhaust hole is prolonged and the functional reliability of the exhaust valve is high.
Description
Technical field
The utility model relates to a kind of outlet valve, particularly relates to a kind of scroll compressor outlet valve.
Background technique
At present, scroll compressor comprises scroll type air compressor, swirl type cold compressor etc.
Existing scroll compressor generally comprises fixed scroll, moving scroll, support, eccentric shaft and anti-rotation mechanism.With certain phase difference, after the radial displacement assembling, can form the crescent shape cavity volume of at least one pair of sealing to intermeshing moving scroll, fixed scroll.When moving scroll when fixed scroll is done the circular orbit motion of certain radius, the cavity volume of these sealings correspondingly enlarges or dwindles, thereby realizes the suction-compression of fluid or the cyclic process of expansion-discharge.
In order to make actual cycle near Ideal Cycle, generally in scroll compressor, increase by an outlet valve, this way will be saved power consumption with respect to no outlet valve.
Described scroll compressor outlet valve comprises fixed scroll, valve block, crooked valve block travel limits plate, fixed scroll is had the exhaustion plate of exhaust port by the center, the vortex circle that is connected on exhaustion plate one side constitutes, valve block travel limits plate, after one endlap of valve block adds, valve block reclines mutually with the outer rim of exhaustion plate another side, and valve block travel limits plate, valve block and exhaustion plate join by the fastening screw trip bolt that passes the three successively, the other end of valve block travel limits plate is away from the tilted state of exhaustion plate and this end the projection on exhaustion plate and surpasses exhaust port, the other end of valve block points to the center of exhaustion plate and the length of valve block is enough to make this end to surpass exhaust port, and the center region of valve block and exhaustion plate another side coincide and reclines.At this moment, valve block is in closed condition, and valve block is in the same horizontal plane near that side of exhaustion plate and the center region of exhaustion plate another side, does not promptly have the gap between valve block and the exhaustion plate.
During this outlet valve work, because the pulsation of air-flow exists the oil stain such as lubricant oil all the time in the outlet valve.Valve block frequently and apace during opening and closing, produces one deck oil film in the center region of exhaustion plate another side, and its thickness is about about 0.1mm.Because the speed of valve block opening and closing is very fast, at this moment oil film can be considered rigid body and forms a boss in described center region, make described center region be higher than valve block that side near exhaustion plate, like this, valve block is in closing closed procedure, and valve block and described center region just can't coincide and recline, the corresponding position of valve block and oil film collide continually and are easy to fatigue, make valve block be easy to fracture, so that this outlet valve inefficacy, this also is a main cause of this outlet valve functional reliability difference.
The model utility content
The technical problems to be solved in the utility model provides the stronger scroll compressor outlet valve of a kind of functional reliability.
For solving the problems of the technologies described above, the utility model scroll compressor outlet valve comprises fixed scroll, valve block, crooked valve block travel limits plate, fixed scroll is had the exhaustion plate of exhaust port by the center, the vortex circle that is connected on exhaustion plate one side constitutes, valve block travel limits plate, after one endlap of valve block adds, valve block reclines mutually with the outer rim of exhaustion plate another side, and valve block travel limits plate, valve block and exhaustion plate join by the fastening screw trip bolt that passes the three successively, the other end of valve block travel limits plate is away from the tilted state of exhaustion plate and this end the projection on exhaustion plate and surpasses exhaust port, the other end of valve block points to the center of exhaustion plate and the length of valve block is enough to make this end to surpass exhaust port, and the nose balance gap is arranged between valve block and the exhaust port.
After adopting such structure, during the work of this scroll compressor outlet valve, by resulting from center region, exhaustion plate another side, can be considered the bed hedgehopping effect of that layer lubricating oil oil film of rigid body and formation boss, make valve block be in the same horizontal plane near that side of exhaustion plate and the respective side of oil film, valve block is in closing closed procedure like this, valve block produces minor change and reclines with oil film is identical under the effect of exhaust pressure, eliminated the nose balance gap between valve block and the exhaust port first, make hermetic seal between valve block and the exhaust port, second avoided the frequent impact at the corresponding position and the oil film edge of valve block, like this, the corresponding position indefatigability of valve block, make not easy-rupturing of valve block, prolonged the working life of valve block significantly, so that the functional reliability of this outlet valve is stronger.
Described gap is 0.05～0.15mm.
Described a kind of preferred gap is 0.1mm.At this moment, prolong comparatively obvious the working life of valve block.
Description of drawings
Fig. 1 is the structural representation of the utility model mode of execution;
Fig. 2 is the working principle schematic representation of the utility model mode of execution.
Embodiment
Below by mode of execution and accompanying drawing thereof the utility model is described in further detail:
