Abstract
The utility model relates to a liquid impact resistance device for a bus air conditioning compressor, which comprises a machine body partition board (1), and is characterized in that the machine body partition board (1) is provided with an oil liquid channel (2) for causing oil liquid in an air suction cavity to inversely flow into a working cavity, the oil liquid channel (2) is provided with a flow discharge valve (7), the flow discharge valve (7) comprises a valve body (3) installed on the oil liquid channel (2), the valve body (3) is internally provided with a channel (4), the channel (4) is internally provided with a spring (5), the other end of the channel (4) acts on a valve sheet (6), and the area of a flow discharge notch on the valve sheet (6) is no less than the air inlet area of the channel (4). The utility model has simple structure, is convenient to manufacture and install, causes accumulated liquid in the air suction cavity to automatically reversely flow into the working cavity through the flow discharge valve, and enables an air exhaust valve sheet to avoid being influenced by liquid impact when working so as to be beneficial to prolonging the service life of the compressor.
Description
Technical field
The utility model relates to a kind of coach air conditioner compressor, and especially a kind of coach air conditioner is with the device that is used for the protection of the anti-liquid hammer of valve board assembly that uses in the compressor, the anti-liquid hammer device of specifically a kind of coach air conditioner compressor.
Background technique
High-power piston type coach air conditioner compressor in the course of the work, in air aspiration cavity, can gather excessive fluid and liquid refrigerants, if this fluid and liquid refrigerants gather and surpass certain amount then the suction and discharge valve block is operated under the rugged environment that produce liquid hammer, influence the working life of compressor, to this, still there is not good solution at present.
Summary of the invention
The purpose of this utility model is that the air aspiration cavity at existing coach air conditioner compressor easily causes hydrops too much to produce liquid hammer, influence suction and discharge valve block working environment, and the problem in shortening compressor life-span designs the anti-liquid hammer device of a kind of coach air conditioner compressor.
The technical solution of the utility model is:
The anti-liquid hammer device of a kind of coach air conditioner compressor, it comprises organism baffle 1, it is characterized in that on described organism baffle 1, being provided with the fluid that makes in the air aspiration cavity and be back to fluid passage 2 in the active chamber, on described fluid passage 2, eduction valve 7 is installed, this eduction valve 7 comprises the valve body 3 that is installed on the fluid passage 2, is provided with passage 4 in the valve body 3, and spring 5 is installed in the passage 4, its the other end acts on valve block 6, and the earial drainage breach area on the valve block 6 is not less than the air inlet area of passage 4.
The beneficial effects of the utility model:
The fluid that the utility model can prevent active chamber effectively is to the backflow generation of phenomenon of air aspiration cavity, reduces gathering of fluid and liquid refrigerants in the air aspiration cavity, avoids liquid hammer when making the work of suction and discharge valve block, thereby prolongs the life-span of compressor.
The utility model is simple in structure, makes, installs all very convenient.
The utility model is back in the active chamber hydrops in the air aspiration cavity by Decompression valves automatically, and the fluid when preventing work simultaneously in the active chamber enters in the air aspiration cavity, thereby makes the work of suction and discharge valve block the time avoid liquid hammer influence, the life-span that helps improving compressor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
The anti-liquid hammer device of a kind of coach air conditioner compressor, it comprises organism baffle 1, on described organism baffle 1, be provided with the fluid that makes in the air aspiration cavity and be back to fluid passage 2 in the active chamber, on described fluid passage 2, eduction valve 7 is installed, this eduction valve 7 comprises the valve body 3 that is installed on the fluid passage 2, is provided with passage 4 in the valve body 3, and spring 5 is installed in the passage 4, its the other end acts on the valve block 6, and the earial drainage area on the valve block 6 is not less than the air inlet area of passage 4.
The utility model mainly is installed between compressor air suction chamber and running gear working area (reserve), being in normally open on one's own time by the eduction valve of being made up of valve body 3, spring 5, valve block 67 makes the fluid that gathers be back to reserve automatically to reach and reduce the purpose that fluid gathers in the air aspiration cavity, can avoid the generation of the operational failure phenomenon of compressor valve board assembly effectively.
When the air aspiration cavity initialization; pressure reduces suddenly; promptly form pressure reduction between air aspiration cavity and the active chamber; the spring pressurized; valve block moves and the passway is blocked to the suction port direction of passage 4; can prevent that fluid from backflowing to air aspiration cavity; compressor valve board assembly is effectively protected; and At All Other Times the section; because the pressure reduction between air aspiration cavity and the active chamber is not enough to overcome spring force; keep a fluid passage between air aspiration cavity and the active chamber thereby make, fluid unnecessary in the air aspiration cavity is back in the active chamber automatically, controlled the accumulated amount of fluid in the air aspiration cavity effectively.
The utility model does not relate to the part prior art that maybe can adopt same as the prior art to be realized.
