Abstract
A valve plate structure of a refrigerator compressor comprises a valve plate body and a suction-exhaust valve port arranged on the valve plate body. On the valve plate body, the exit of the suction-exhaust valve port extends upward to form a sealing convex ring with round-arc cross section. As a suction-exhaust valve plate is in contact with the valve plate body by the sealing convex ring, original surface contact of the contact point is replaced by line contact, thus the contact point can adjust voluntarily under pressure and always maintains the sealing effect, thus improving the sealing performances of the suction-exhaust valve plate and the suction-exhaust valve port and solving the problem of leakage of the valve plate body of the refrigerator compressor during running.
Description
(1) technical field
The utility model relates to the plate member in the freezer compressor, specifically, relates to a kind of valve board structure of freezer compressor.
(2) background technique
Plate member in the freezer compressor plays crucial effects in whole compressor, its structure comprises the valve plate body, be opened in the suction and discharge valve port on the valve plate body, and the suction and discharge valve block that is encapsulated in the suction and discharge valve port, the surface of suction and discharge valve block and valve plate body is close to, make its point of contact form a seal ring, be the face contact.General suction and discharge valve block is affixed on suction and discharge sealing valve port ring place, the machining accuracy of dependence suction and discharge valve port is adjacent to suction and discharge valve block and suction and discharge valve port and is unlikely to leak gas at suction and discharge valve port place, just the requirement on machining accuracy to the seal ring place of suction and discharge valve port is very high for this, planeness and surface roughness such as the suction and discharge valve port, if precision reduces a little, will produce poorly sealed, thereby make the gas backstreaming of discharge reduce displacement, motor is under the situation of 2900r/min running, the micro-leakage that produced of suction and discharge valve block all is very important each time, can cause the reduction of compressor refrigerating capacity.
(3) summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides the valve board structure of the higher freezer compressor of a kind of sealing, has solved the leakage problem of freezer compressor valve plate body in running, makes the air displacement of compressor obtain to improve.
The technical scheme in the invention for solving the technical problem is: a kind of valve board structure of freezer compressor, comprise the valve plate body, and being opened in suction and discharge valve port on the described valve plate body, the outlet port that is positioned at described suction and discharge valve port on described valve plate body extends upward and is provided with the sealing bulge loop that shape of cross section is a circular arc.
The utility model in use, the suction and discharge valve port place on the valve plate body is packaged with the suction and discharge valve block, makes the suction and discharge valve block be close to the sealing bulge loop at suction and discharge valve port place, thereby suction and discharge valve port place can not leaked gas.
The beneficial effects of the utility model are: because the suction and discharge valve block contacts by the sealing bulge loop with the valve plate body, its point of contact is made contact to for the line contact by original face, point of contact can be adjusted voluntarily under the effect of pressure, remain the effect of sealing, improved the sealing of suction and discharge valve block and suction and discharge valve port, solved the leakage problem of freezer compressor valve plate body in running, and the effect that improves noise arranged on certain degree, the most important thing is to improve the efficiency ratio of freezer compressor, make the compressor operating time shorten, reduce power consumption.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of valve board structure of freezer compressor, comprise valve plate body 1, and be opened in suction and discharge valve port 2 on the described valve plate body 1, the outlet port that on described valve plate body 1, is positioned at described suction and discharge valve port 2 extend upward be provided with shape of cross section be circular arc sealing bulge loop 3. in use, suction and discharge valve port 2 places on valve plate body 1 are packaged with suction and discharge valve block 4, make suction and discharge valve block 4 be close to the sealing bulge loop 3 at suction and discharge valve port 2 places, thereby suction and discharge valve port 2 places can not leaked gas.
Claims (1)
1. the valve board structure of a freezer compressor, comprise the valve plate body, and be opened in suction and discharge valve port on the described valve plate body, it is characterized in that: the outlet port that is positioned at described suction and discharge valve port on described valve plate body extends upward and is provided with the sealing bulge loop that shape of cross section is a circular arc.
