Abstract
The present invention, exhaust valve structure design of large displacement high pressure swinging piston compressor is the supplement of the invention in the patent application number of 200610115894.4, and aims at eliminating the reverse acting force of high pressure gas inside the exhaust pipe on the exhaust valve so as to ensure the required tight closing and fast opening of exhaust valve. The present invention has unobstructed flow of gas, low power consumption and high operation efficiency.
Description
Technical field the present invention relates to a kind of swing piston compressor exhaust valve structure, relates in particular to a kind of big discharge capacity high pressure swing piston compressor exhaust valve structure.
Exhaust valve is subjected to the acting in opposition of outlet pipe mesohigh pressurized gas during the work of the big discharge capacity high pressure of background technique swing piston compressor, and the present invention carries out the design of special construction for solving this problem to exhaust valve.
Not only size is big for big discharge capacity high pressure swing piston compressor exhaust valve, and the row of being subjected to manages the effect of mesohigh pressurized gas opposition, and as with 100 square centimeters of calculating of medium size exhaust valve lifting surface area, active force is 60 kgf/centimetres in the outlet pipe
2, the suffered power of exhaust valve is 6000 kgfs, as the exhaust valve structure in the motor will bring the series of negative influence using, and designs the structure that makes new advances for this reason.General engine exhaust port is owing to be subjected to the effect of gas pressure in the cylinder, and exhaust valve annular edge and exhaust valve seat design are before entering exhaust.
Summary of the invention high pressure swing piston compressor is because exhaust valve is subjected to the effect of pressurized gas in the outlet pipe, thereby exhaust valve annular edge and exhaust valve seat design are in exhaust duct in the big discharge capacity high pressure swing piston compressor exhaust valve design, and this and daily finding engine exhaust port are diverse structural type.
The feature of new structure is combined by the part of several interdependent interwovenesses each other, and these are: the contacted annular edge design of exhaust valve and exhaust valve seat is passed through the exhaust valve annular edge through exhaust valve seat earlier again in exhaust duct; Among exhaust valve spring design another air chamber outside the high pressure-temperature air flue; The exhaust valve seat design is at the exhaust end that leaves the compression cylinder connecting port, rather than inlet end; Cam is by being used for exhaust valve rod to the exhaust valve apical ring with masterpiece; Fixed cover and organism top case connect and compose another air chamber 20 with screw on the spring; Fixed cover 17, one ends connection gas clamping sleeve 19 valve clamping sleeves 19 contact with melon seeds lobe 9 under spring 4 effects on the exhaust valve spring 4 one ends connection spring.
The big discharge capacity high pressure of description of drawings swing piston compressor exhaust valve structure is seen accompanying drawing 1.
1-organism top case, 2-exhaust valve, 3-exhaust valve guide, 4-exhaust valve spring, 5-exhaust valve cam and camshaft, 6-exhaust valve apical ring, 7-be fixed in the rolling bearing of apical ring, the screw of 8-fixedly exhaust valve apical rings and valve stem, 9-be flush-mounted in two fixed blocks (claiming the melon seeds lobe again) in the exhaust valve push rod, 10-exhaust valve seat, 11-exhaust valve seat fixed block, 12-exhaust valve seat fixed block and organism top case attachment screw, 13-exhaust duct, 14-exhaust valve annular edge, 15-exhaust valve rod, 16-compression cylinder connecting port, fixed cover on 17-spring, fixed cover attachment screw on 18-spring, 19-valve clamping sleeve, another outer air chamber of 20-high pressure-temperature air flue is used as installs valve spring.
Though the embodiment exhaust valve structure is different from the exhaust valve in the general Reciprocating engine, processing there is no special difficulty, just can process with the equipment of general engine works processing exhaust valve.
Because exhaust valve and the contacted exhaust valve annular edge of exhaust valve seat and exhaust valve seat design be in the import of exhaust duct, thereby make the opposition of outlet pipe mesohigh pressurized gas to exhaust valve, from unfavorable become favourable.Working cylinder is in air inlet and initial compression work, and exhaust valve is in the double action of atmospheric pressure in the outlet pipe of spring force closely closes, and prevents the leakage of gas.And when needs are opened in cam action power, cylinder under the compressed gas forces double action exhaust valve open rapidly, guaranteed the unobstructed circulation of gas and reduced the impact force of exhaust valve exhaust valve seat, reduced the noise in the work.Because exhaust valve can be opened rapidly, big circulation area is arranged during unlatching, reduced the airflow resistance, exhaust valve can cut out again in strictness in the time of need closing, this has just reduced air-flow loss in the course of the work, improved the working efficiency of whole compressor, the mechanical efficiency of adding this kind new type compressor is high especially, has just guaranteed that this is an energy-saving compressor that the spy is good.
Because the structural feature of new designing and arranging valve, in exhaust valve spring design another air chamber outside the high pressure-temperature air flue, this has reduced the requirement to high spring force under the exhaust valve spring high temperature.Owing to adopt exhaust valve apical ring and apical ring rolling bearing structure, reduced the loss of cam drive power, improved the operating life of exhaust valve and exhaust valve seat, greatly reduce the slapping noise of exhaust valve to exhaust valve seat.
The installation of exhaust valve needs dress exhaust valve guide earlier, reinstalls exhaust valve, and exhaust valve seat press fit over earlier in the exhaust valve fixed block, and the exhaust valve fixed block is installed in the organism top case with screw again.
For guaranteeing the concentric of exhaust valve and exhaust seat, can pull down exhaust valve, sliding ream bar and the ream of being fitted in exhaust valve guide, reinstall exhaust valve seat fixed block and exhaust valve seat, on top by hand or lathe rotate the ream bar, the cutlery ream is promptly processed valve seat annular working limit, can guarantee the concentric of exhaust valve and exhaust valve seat.
