Accompanying drawing explanation
Clearly understand to make the object of compressor slide valve assembly of the present utility model and refrigeration screw compressor, technological scheme and advantage, below in conjunction with concrete drawings and the specific embodiments, compressor slide valve assembly of the present utility model and refrigeration screw compressor are further elaborated.
Fig. 1 is the generalized section of an embodiment of compressor slide valve assembly of the present utility model;
Fig. 2 is the part-structure sectional drawing of an embodiment of refrigeration screw compressor of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with embodiment.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
See Fig. 1, the compressor slide valve assembly of the embodiment that the utility model provides, comprises guiding valve 100, slide valve lever 200, dunnage 300 and connecting rod 400.Wherein, guiding valve 100 is connected with slide valve lever 200.Dunnage 300 is arranged on the body of compressor, coordinates (0.01-0.02 millimeter), prop up the rear end of slide valve lever 200 with the backend space of slide valve lever 200.Connecting rod 400 is arranged on the body of compressor, coordinates (0.01-0.02 millimeter), prop up the front end of slide valve lever 200 with the front space of slide valve lever 200.Slide valve lever 200 supports as bearing by dunnage 300 and connecting rod 400, again guiding valve 100 is propped up by slide valve lever 200, thus make guiding valve 100 keep certain distance with the body of compressor, avoid adding in unloading running by body cambered surface support guiding valve 100, decrease guiding valve 100 and body area of contact, reduce frictional force, effectively can solve the scratch of compressor slide valve chamber and noise problem.
Wherein, dunnage 300 and connecting rod 400 are equivalent to sliding bearing, to ensure that slide valve lever 200 can be free to slide.The material of dunnage 300 and connecting rod 400 can be tin bronze, and intensity is high, and wear resistance is good.The concrete structure of connecting rod 400 can be a boss, and structure is simple, is convenient to manufacture and assembling.
See Fig. 1, the compressor slide valve assembly of another embodiment that the utility model provides, the basis of above-described embodiment also comprises support ring 500.Support ring 500 is arranged on guiding valve 100, with slide valve lever 200 interference fit, is mainly used in fixing slide valve lever 200.Traditional slide valve lever and the chien shih of guiding valve are threaded connection, and by arranging support ring 500 and slide valve lever 200 interference fit on guiding valve 100 in the utility model, realize the connection of guiding valve 100 and slide valve lever 200.Support ring 500 can be set to one or more, is preferably two, is separately positioned on the two ends of guiding valve 100, makes guiding valve 100 more stable with the connection of slide valve lever 200 like this on the basis saved production cost.
It should be noted that, the utility model has carried out adding long process to slide valve lever 200 itself, the rear and front end of the slide valve lever 200 after lengthening is propped up by dunnage 300 and connecting rod 400 respectively, middle part is assembled together by support ring 500 and guiding valve 100, structure is more stable, avoids guiding valve 100 and directly contacts with compressor block in running.
See Fig. 1; the compressor slide valve assembly of another embodiment that the utility model provides; the basis of above-described embodiment also comprises fastening screw trip bolt 600, and fastening screw trip bolt 600 is arranged between guiding valve 100 and slide valve lever 200, guarantees to locate between guiding valve 100 and slide valve lever 200 reliably.
During assembling, can first at the center of guiding valve 100 processing ∮ 40 endoporus, and then process 2 support rings 500, support ring 500 is fixed in the endoporus of guiding valve 100, finally slide valve lever 200 is loaded the guiding valve 100 being inserted in support ring 500, use fastening screw trip bolt 600 to be fixed by slide valve lever 200 from the top of guiding valve 100, guiding valve 100 is loaded body, completes assembling.
See Fig. 1, the compressor slide valve assembly of another embodiment that the utility model provides, the basis of above-described embodiment also comprises oily piston 700, and oily piston 700 is connected by screw with slide valve lever 200.Oil piston 700 is the stressed parts main when adding unloading of guiding valve 100.
Correspondingly, participate in Fig. 2, the utility model also provides a kind of refrigeration screw compressor, and this refrigeration screw compressor comprises the compressor slide valve assembly that above-mentioned any embodiment provides.Wherein, guiding valve 100 and slide valve lever 200 are arranged in body, and slide valve lever 200 lengthens on the basis of conventional construction, and dunnage 300 props up the rear end of slide valve lever 200, and the front end of slide valve lever 200 propped up by connecting rod 400.Slide valve lever 200 supports as bearing by dunnage 300 and connecting rod 400, and guiding valve 100 is propped up again by slide valve lever 200, thus makes guiding valve 100 keep certain distance with the body of compressor, and repeating part is no longer superfluous to be stated.
Guiding valve and the slide valve lever of traditional refrigeration screw compressor are threaded connection, and oily piston and slide valve lever are also for being threaded.Oil piston supports one end of guiding valve, and the other end of guiding valve directly contacts with compressor block, and guiding valve supports by body.Owing to only having 0.03-0.05mm gap between guiding valve and body, so guiding valve is easy to rub with body adding in uninstall process, cause piston chamber scratch and noise problem, even cause that helical-lobe compressor guiding valve is stuck waits serious accident.
The compressor slide valve assembly that the utility model provides and refrigeration screw compressor, when adding unloading, oil piston transmits reciprocating force to guiding valve, slide valve lever after lengthening runs when being propped up by dunnage and connecting rod, or else guiding valve also just contacts or runs when contacting body less, the probability of guiding valve generation scratch and generation noise just can reduce greatly in such cases, thus ensures the operation of compressor long-term smooth.
Above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
