Abstract
The utility model discloses an exhaust hood enhanced type air suction device, which solves the problem of the prior art that an exhaust hood of an air suction device of a reciprocating compressor is not firm in connection and is dropped easily. The air suction device comprises an air cylinder (1) with an inner cavity, a piston (2) sleeved in the air cylinder (1), a main gas channel (3) arranged in the piston (2), an auxiliary gas channel (4) arranged on the piston (2) and used for communicating the main gas channel (3) with the outer side, an air suction valve (5) fixed on one end of the piston (2) through a fastening bolt, an exhaust hood (6) sleeved on the end part of the air cylinder (1), and a vent valve (7) arranged in the exhaust hood and movably connected with the air cylinder (1) through a valve spring; and the other end of the piston (2) extends out of the air cylinder (1) and is also provided with a connecting body (8), and the exhaust hood (6) is in a dome shape and is tightly connected to the end part of the air cylinder (1) through a self-fastening bolt.
Description
Technical field
The utility model relates to a kind of suction means, specifically, is a kind of exhaust hood reinforcing type suction means.
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: exhaust hood only is buckled in the end of cylinder in the suction means of traditional compressor, its connection is very insecure, often come off in addition in the working procedure, not only reduce working efficiency, and increased cost of equipment maintenance.
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:
Exhaust hood reinforcing type suction means, 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 exhaust hood is the dome cap shape and is fastenedly connected in the cylinder end by self-locking bolt.
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) exhaust hood is the dome cap shape and is fastenedly connected in the cylinder end by self-locking bolt in the utility model, self-locking bolt can be locked voluntarily according to external force, effectively prevented the defective that exhaust hood comes off in addition because gas impacts, not only guarantee manufacturing efficiency, and reduced widely cost of equipment maintenance;
(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, exhaust hood reinforcing type suction means, 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 exhaust hood 6 is fastenedly connected in cylinder 1 end for the dome cap shape and by self-locking bolt.This self-locking bolt can be locked voluntarily according to external force, has effectively prevented the defective that exhaust hood comes off in addition because gas impacts, and has not only guaranteed manufacturing efficiency, and has reduced cost of equipment maintenance widely.
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.
