Description
Technical field
The utility model relates to a kind of suction means, specifically, is a kind of suction means with thin plate air valve.
Background technique
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to high pressure.It is the heart of refrigeration system, it sucks the refrigerant gas of low-temp low-pressure from sucking pipe, after driving piston it is compressed by motor rotation, discharge the refrigerant gas of High Temperature High Pressure to outlet pipe, for refrigeration cycle provides power, thus the refrigeration cycle of realization compression, condensation, expansion, evaporation (heat absorption).And the suction means in the compressor is the heart of whole compressor.At present, the suction means of compressor all is to do reciprocatory motion by piston to carry out air-breathing, exhaust on the market, mainly there is following shortcoming in it: the Aspirating valves in the suction means of compressor is very important component, but traditional Aspirating valves thickness is thicker, so not only reduced gas flow area, and the distortion of thicker Aspirating valves is comparatively difficult, has affected the normal operation of suction means.
The model utility content
The purpose of this utility model is to overcome defects, provide a kind of overall structure simple, realize easily suction means.
To achieve these goals, the scheme of the utility model employing is as follows:
Suction means with thin plate air valve, comprise the cylinder with inner chamber, be socketed in this cylinder and the piston that is flexibly connected with it, be arranged on the main gas channel in the piston, be arranged on the piston in order to be communicated with the secondary gas channel in main gas channel and the external world, be fixed on the Aspirating valves of piston one end by clamping bolt, be socketed in the exhaust hood of cylinder end, and be arranged in this exhaust hood and by the outlet valve of valve spring with the cylinder flexible connection; It is outside and also be provided with one in this end in order to connecting the connecting body of power source that the other end of described piston extends to cylinder, and described Aspirating valves is the disc of thin-slab structure, and its size is complementary with piston.
Further, described main gas channel and secondary gas channel are cylindrical, and the radius of secondary gas channel is 1/4th of main gas channel radius.
Further, the internal chamber wall close contact of described piston and cylinder.
Simultaneously, described exhaust hood adapter sleeve is connected on the end of cylinder.
Further, described Aspirating valves and outlet valve are positioned at the same side.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost, realization convenience;
(2) Aspirating valves is the disc of thin-slab structure in the utility model, and its size is complementary with piston, thin-slab structure has not only reduced the thickness of Aspirating valves widely, increased gas flow area, and when guaranteeing the air valve normal operation, the comparatively traditional Aspirating valves of its distortion is more prone to, thereby has improved widely the working efficiency of compressor air suction device;
(3) piston and cylinder close contact in the utility model, effectively prevented piston in doing reciprocatory motion owing to its with cylinder between be connected the defective that the slit leaks gas;
(4) material therefor is common on the market common material in the utility model, and its cost is cheap than the suction means of traditional compressor, has established favourable basis for it promotes the use on a large scale.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, the component name that reference character is corresponding is called: 1-cylinder, 2-piston, 3-master's gas channel, the secondary gas channel of 4-, 5-Aspirating valves, 6-exhaust hood, 7-outlet valve, 8-connecting body.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, suction means with thin plate air valve, comprise the cylinder 1 with inner chamber, be socketed in this cylinder 1 and the piston 2 that is flexibly connected with it, be arranged on the main gas channel 3 in the piston 2, be arranged on the piston 2 in order to be communicated with main gas channel 3 and extraneous secondary gas channel 4, be fixed on the Aspirating valves 5 of piston 2 one ends by clamping bolt, be socketed in the exhaust hood 6 of cylinder 1 end, and be arranged in this exhaust hood and by the outlet valve 7 of valve spring with cylinder 1 flexible connection; It is outside and also be provided with a connecting body 8 in order to connect power source in this end that the other end of described piston 2 extends to cylinder 1, and described Aspirating valves 5 be the disc of thin-slab structure, and its size and piston 2 are complementary.This thin-slab structure has not only reduced the thickness of Aspirating valves widely, increased gas flow area, and when guaranteeing the air valve normal operation, the comparatively traditional Aspirating valves of its distortion is more prone to, thereby has improved widely the working efficiency of compressor air suction device.
In the present embodiment, for so that gas communication is quicker, it is cylindrical that described main gas channel 3 and secondary gas channel 4 are, and the radius of secondary gas channel 4 is 1/4th of main gas channel 3 radiuses; Described exhaust hood 6 adapter sleeves are connected on the end of cylinder 1.
In the present embodiment, in order to prevent suction means in when work phenomenon that leaks air, the internal chamber wall close contact of described piston 2 and cylinder 1.
In the present embodiment, in order better to realize present embodiment, described Aspirating valves 5 is positioned at the same side with outlet valve 7.
According to above-described embodiment, can well realize the utility model.
