When the compressor exhausts, high-pressure gas can instantaneously jack the exhaust valve block of cover on the flange gas vent and discharge from the flange gas vent, and the exhaust valve block can be periodic open and closed, and the valve block can high-speed impact stopper at the valve block opening in-process, and then can lead to the aggravation of valve block fracture and compressor noise level.
The traditional exhaust valve plate limiter mainly comprises a root section, a waist section and a head section, wherein the root section is provided with a rivet hole for connecting an exhaust valve plate and a flange through a rivet. The traditional limiter is mainly characterized in that the root section adopts a parallel section design, is wide in width and is used for fixing and restraining the whole exhaust assembly; the waist section is a curve section, the width of the waist section is narrower than that of the root section, the waist section and the root section are designed to be equal in width, and the waist curve is used for gradually attaching the exhaust valve plate in the ascending process; the head section is often of rectangular design and is wider in width for limiting the total lift of the valve plate.
The condition that a valve block impacts a stopper to be broken often occurs in the actual use process of the conventional stopper, and a crack source is mostly generated at the head of the valve block, namely the contact area of the valve block and the stopper head. In order to better solve the problem of impact fracture of the valve plate, a new stopper is urgently needed to replace the existing scheme.
The prior art discloses a compressor baffle, a compressor and an air conditioner, wherein the head section of a limiter (baffle) is arranged to be groove-shaped, and a two-layer laminated flexible structure is formed. When the valve plate is impacted, the impact speed and the stress change of the valve plate on the baffle can be effectively relieved, on one hand, the rigidity of the baffle structure is guaranteed, on the other hand, the impact of the exhaust valve plate on the valve plate baffle is relieved, and the noise level is reduced. But this scheme probably can cause the fracture of stopper head in actual implementation, and the impact of valve block and stopper head itself will cause very big impact force to the stopper head, because the stopper head is the recess dress and is changeed and make this position fracture.
The prior art also discloses a baffle of the compressor, a gas exhaust structure of the compressor and the compressor, wherein a raised part of a limiter of the compressor is provided with a plurality of laminations towards one side of a valve plate, the scheme can play a role of impact buffering on the valve plate by utilizing the plurality of laminations, but the strength of the laminations is obviously smaller than that of the material of the valve plate if the strength of the limiter is considered, and the laminations are likely to break. And the stopper that has different lamination and the lamination has different curvatures processes the degree of difficulty huge, is difficult to realize.
The invention provides a limiting device of an exhaust valve plate and a compressor, which are researched and designed because the problems that the valve plate is broken when the valve plate impacts the limiting device, the impact breakage rate of the valve plate can be reduced by changing the structure of the limiting device and the like are often caused by the use of the traditional compressor exhaust limiting device in the prior art.

Detailed Description
As shown in fig. 2 to 4, the present invention provides a limiting device 100 for an exhaust valve plate, wherein:
including root section 1, waist section 2 and head section 3, root section 1 waist section 2 with head section 3 connects as an organic wholely, just waist section 2 is located root section 1 with between the head section 3, the thickness of the free end 31 department of head section 3 is h2, head section 3 with the thickness that waist section 2 meets the department is h3 to there are h2< h 3.
According to the invention, the head section in the limiting device of the exhaust valve plate is set to be thicker at the joint with the waist section than at the free end, so that the head section can be formed into a variable-thickness design structure, the rigidity of the head section at the free end is smaller than that at the joint with the waist section, when the valve plate impacts the limiter, the head of the limiter can generate larger deformation compared with the traditional scheme, but the deformation is still smaller as a whole, the total valve plate lift cannot be greatly influenced, and the impact action of the valve plate is weakened because the deformation is increased and more impact energy is inevitably converted, so that the fracture rate of the valve plate is reduced, and the noise level of the compressor is improved.
Fig. 1 shows a conventional stopper structure, which is mainly divided into a root section, a waist section, and a head section. The root section is restrained with the baffle and the flange through rivets or screws, the root section adopts the parallel section design, the waist section is the curve section, the head section is the rectangle design usually, the whole stopper is the design of uniform thickness, and the triplex all is the design of uniform width, that is to say the stopper is the design of equal rigidity, the stopper of equal rigidity often can bring high valve block impact fracture rate when compressor actual operation.
The technical scheme provided by the invention adopts the variable-rigidity limiter, and has the advantage that the head of the limiter has better flexibility than the waist and the root sections. When the valve plate collides with the stopper, the waist section of the stopper, which is deviated to the root side, still keeps larger rigidity to resist the large deformation of the stopper, the stopper can still keep the valve plate and the stopper to be well attached towards the molded line of the valve plate side unchanged, and the waist section of the stopper, which is deviated to the head side, still can cause the deformation caused by the collision of the valve plate and the stopper due to the reduction of the rigidity, but the rigidity of the part is still far larger than the rigidity of the valve plate, so that the valve plate can generate certain deformation, but the influence on the integral lift of the valve plate is not large. Based on the design of the technical scheme, the energy brought by the slapping of the valve plate can be greatly absorbed, the impact effect of the valve plate and the limiting stopper is reduced, and the impact noise can be obviously reduced.

The head section is arranged to be gradually thinned from the joint of the head section and the waist section to the free end, the rigidity of the head section can be gradually reduced along the length direction of the limiter to the direction of the free end, and when the valve plate impacts the limiter, the head of the limiter can also deform more greatly and gradually, so that more impact energy can be converted, the impact effect of the valve plate is weakened, the fracture rate of the valve plate is reduced, and the noise level of the compressor is improved.
The molded lines of the variable thickness stopper close to the valve plate side still remain unchanged, namely only the stopper far away from the valve plate side is processed when the thickness is changed, the molded lines are processed close to the valve plate side according to the traditional scheme (the molded lines of the lower end face of the baffle in fig. 2 are not changed, namely the original molded lines are reserved, the variable thickness baffle is equivalently reserved with the same shape of the lower end face on the basis of the baffle with the same thickness, and only the molded lines of the upper end face of the baffle are changed to gradually reduce the thickness), so that the scheme does not change the traditional scheme stopper and valve plate wrapping effect, and the total lift of the valve plate is basically unchanged.
Preferably, the thickness of the waist section 2 at the junction with the root section 1 is h1, and h3< h 1.
According to the invention, the thickness of the joint of the waist section in the limiting device of the exhaust valve plate and the root section is larger than that of the joint of the waist section and the head section, so that the waist section can be formed into a variable-thickness design structure, the rigidity of the waist section is smaller at the joint of the waist section and the head section than at the joint of the waist section and the root section, when the valve plate impacts the limiter, the waist of the limiter can be deformed more than that of the traditional scheme, more impact energy is further converted, the impact action of the valve plate is weakened, the fracture rate of the valve plate is reduced, and the noise level of the compressor is improved.

Further through setting up the waist section into from meeting with the root section to meeting with the head section and being the structure form of tapering, can also make the rigidity of waist section reduce from the root to the direction of head along the length direction of stopper gradually, make when the valve block strikes the stopper, the stopper waist can also produce bigger and more gradual change deformation, further can convert more impact energy, make valve block striking effect weakening, reduce the valve block fracture rate, promote compressor noise level.
Preferably, the relation between h1 and h2 is satisfied: h1/h2 is more than or equal to 1.5 and less than or equal to 3; and/or the root section 1 is of an equal thickness structure and has a thickness h 1; and/or the variable thickness of the waist section 2 is formed by processing and thinning one side surface of the waist section 2 back to the valve plate
Fig. 2 shows a variable thickness stopper of the present invention, which is mainly different from the conventional stopper structure in that the waist section and the head section of the variable thickness stopper are both designed to be variable in thickness, i.e. the thickness is gradually changed from the parallel section thickness h1 to the head thickness h2, and in order to ensure the variable thickness stopper to achieve the best effect, the following relationships exist between h1 and h 2: h1/h2 is more than or equal to 1.5 and less than or equal to 3; in addition, the molded lines of the variable thickness stopper close to the valve plate side still remain unchanged, namely only the stopper far away from the valve plate side is processed when the thickness is changed, the molded lines of the baffle lower end face close to the valve plate side are still processed according to the traditional scheme (the molded lines of the baffle lower end face in fig. 2 are not changed, namely original molded lines are reserved, the variable thickness baffle is equivalently reserved with the lower end face molded lines unchanged on the basis of the baffle with the same thickness, and only the molded lines of the baffle upper end face are changed to gradually reduce the thickness), so that the traditional scheme is not changed, the winding and pasting effect of the stopper and the valve plate is not changed, and the total lift of the valve plate is basically unchanged.
The technical scheme has the advantages that the root part of the limiting stopper is thicker than the head part, so that the limiting stopper can be better ensured not to generate large deformation, the rigidity of the limiting stopper is gradually reduced along with the reduction of the thickness, when the valve plate impacts the limiting stopper, the head part of the limiting stopper can generate larger deformation compared with the traditional scheme, but the deformation is still smaller on the whole, the total valve plate lift cannot be greatly influenced, more impact energy is inevitably converted due to the increase of the deformation, so that the impact action of the valve plate is weakened, so that the fracture rate of the valve plate is reduced (in the same impact process, the initial energy is constant, the deformation is larger in the impact process, namely more energy is converted to be stored in a material for changing the performance, the impact action is weakened, in other words, a moving object impacts a hard object and a soft object, and certainly impacts the hard object with larger impact force, this is due to the greater deformation energy that is imparted upon hitting a soft object. ) And the noise level of the compressor is improved. Fig. 3 is a three-dimensional view of a variable thickness stopper according to the present invention.
Preferably, the width of the waist section 2 where it meets the root section 1 is b1, the width of the waist section 2 where it meets the head section 3 is b2, and the width of the waist section 2 is set to b1> b 2. According to the invention, the waist section in the limiting device of the exhaust valve plate is set to be wider at the joint with the root section than at the joint with the head section, so that the waist section can be formed into a variable-width design structure, the rigidity of the waist section is smaller at the joint with the head section than at the joint with the root section, when the valve plate impacts the limiter, the waist of the limiter can be deformed more than that of the traditional scheme, more impact energy is further converted, the impact action of the valve plate is weakened, the fracture rate of the valve plate is reduced, and the noise level of the compressor is improved.
Preferably, the width of the waist section 2 is set to: gradually decreases from the junction with the root section 1 to the junction with the head section 3; and/or varies linearly or non-linearly from the junction with the root section 1 to the junction with the head section 3. Further through setting up the waist section to be the structure form that narrows down gradually from meeting department with the root section to meeting department with the head section, can also make the rigidity of waist section reduce from the direction of root to head along the length direction of stopper gradually for when the valve block strikes the stopper, the stopper waist can also produce bigger and more gradual change deformation, further can convert more impact energy, make valve block striking effect weakening, reduce the valve block fracture rate, promote compressor noise level.
