Novel protected range.
As depicted in figs. 1 and 2, the flange of the present embodiment includes: flange body 10, and flange body 10 has gas vent, row
Reinforcement structure is equipped in stomata, reinforcement structure is by exhaust port separation at multiple exhaust holes 11.Wherein, flange body 10 is located at row
Part around stomata is delivery valve seat, and the D in Fig. 2 refers to the thickness of delivery valve seat.
Using the flange of the present embodiment, reinforcement structure is set in gas vent, reinforcement structure can be reinforced at gas vent
The local stiffness value at gas vent can be improved under identical valve seat thickness condition in structural strength, reduces delivery valve seat in complexity
Caused deflection under external force, delivery valve seat deformation is more serious when solving delivery valve seat deflection more than certain value to incite somebody to action
Seizure of piston and delivery valve seat deflection hour gas vent clearance volume excessive the problem of leading to compressor volume low efficiency.
In the present embodiment, reinforcement structure includes multiple reinforcing ribs 12, and the first end of each reinforcing rib 12 is connected to exhaust
On the inner wall in hole, the second end of each reinforcing rib 12 reinforcing rib 12 adjacent thereto is connected.The structure of reinforcement structure is simple, is convenient for
Processing and manufacturing reduces production cost.
In the present embodiment, the angle of the center line of two reinforcing ribs 12 of arbitrary neighborhood is identical, further easy to process.
Specifically, the length of each reinforcing rib 12 is identical, i.e., multiple reinforcing ribs form star shape.
In the present embodiment, there are three reinforcing rib is set, proof strength while, guarantees leaving area.
In order to further strengthen the structural strength at gas vent, in the present embodiment, the thickness and gas vent of reinforcing rib 12
Length it is identical.
In the present embodiment, round and smooth mistake between the inner peripheral surface of the opposite two sides and gas vent of the first end of reinforcing rib 12
It crosses, facilitates processing and manufacturing, stress concentration can be effectively relieved, enhance partial structurtes intensity.In the present embodiment, the two of arbitrary neighborhood
Rounding off between the side of the second end of a reinforcing rib 12, facilitates processing and manufacturing, and stress concentration, enhancing part can be effectively relieved
