Description
Technical field
The present invention relates to a kind of discharge valve door device of hermetic type compressor, particularly relate to a kind of discharge valve door device of the hermetic type compressor that spues in the compressed actuation fluid of pressing chamber inner control.
Background technique
Fig. 1 is the internal structure generalized section according to the common compressor of prior art.As shown in the figure, above-mentioned existing common compressor, it mainly comprises following structure member:
By the seal container 1 that upper container 1t and bottom container 1b constitute, this seal container 1 inside is provided with frame 2, is fixed with stator 3 on the frame 2, and utilizes spring 2S that frame 2 is supported in the seal container 1.
In the upper end of crankshaft 5, be provided with the centrifugal fin 5b that departs from crankshaft 5 rotating centers; Opposite side at centrifugal fin 5b is provided with statocone 5c; Crankshaft 5 can rotate and play frames 2 simultaneously.
The inside of crankshaft 5 is provided with oil groove 5a; And the lubricant oil L that is positioned at seal container 1 bottom can direct into the top of above-mentioned frame 2 and disperse and comes by oil groove 5a; The underpart of crankshaft 5 is provided with can aspirate lubricant oil L, and it is delivered to the aspirator 5d of oil groove 5a.
The cylinder 6 that is built-in with pressing chamber 6 ' is arranged on the frame 2; In pressing chamber 6 ', be provided with by the centrifugal fin 5b of crankshaft 5 and the piston 7 that is connected with connecting rod 8; At the front end of cylinder 6, be provided with valve member 9, this valve member 9 can be controlled the condensing agent inflow or flow out pressing chamber 6 '; And on valve member 9, be fixed with top cover 10; On top cover 10, in order to transmit condensing agent to pressing chamber 6 ', absorbing silencer 11 is mounted on the valve member 9.
Seeing also shown in Figure 2ly, is the main structure sectional drawing of valve member 9.The front end of cylinder 6 is provided with valve plate 9p; On valve plate 9p, in order to prevent from spuing of compressed condensing agent, be provided with to fix the fixed hole 9g of its structure; Connect valve plate 9p, connect and be provided with discharge opening 9e; The edge of discharge opening 9e forms valve (door) the seat 9t higher relatively than periphery; The other end of valve plate 9p connects and forms suction port (not shown).
Fixed hole 9g is provided with the valve 9v that spues that opens and closes discharge opening 9e; Seeing also shown in Figure 3ly, is the structural plan figure of valve 9v of spuing, its front end be arranged on the corresponding position of discharge opening 9e on, be the 9v ' of switching portion that opens and closes discharge opening 9e; The other end of valve 9v of spuing is to be positioned that device 9r pushes down and fixing fixing part 9m; The 9v ' of switching portion connects by being connected napex 9n with fixing part 9m.
Valve spring sheet 9s is provided with and is rugosity.The front end of this valve spring sheet 9s can be controlled the vibration of the above-mentioned valve 9v that spues; Its other end is pushed down by above-mentioned positioning work piece 9r and fixing fixing part, and is fixing with the fixing part 9m of the valve 9v that spues.
