Description
Technical field
The utility model relates to compressor field, is specifically related to a kind of oilless compressor.
Background technique
Name is called " a kind of high efficient gas and liquid recovery compressor " (application number: describe a kind of compressor in patent documentation 201320211248.3), the defect that traditional compressor air inlet-exhaust valve circulation area is little in order to solve for it, drag losses large, cylinder utilization ratio is low, compressor efficiency is low, air-breathing spool is arranged on piston head, exhaust plug is arranged on cylinder head, compressed gas and liquid can be discharged completely each time when compressor operating like this, increase circulation area, reduce the pressure loss, improve the efficiency of compressor.But, in the program, exhaust plug is positioned at the outside of cylinder head portions completely, in order to improve the sealing effect between exhaust plug and cylinder, the end end face of exhaust plug is just needed to arrange larger, make the end face of exhaust plug can gluing, sealing complete in the end face of cylinder, along with the continuous operation of compressor, the pressure and temperature that exhaust plug bears constantly promotes, because exhaust plug end area is large, it easily deforms, and causes exhaust valve closure sternly not revealed, and compressor compresses efficiency reduces greatly maybe cannot be compressed.
Summary of the invention
The purpose of this utility model is just to provide a kind of oilless compressor, and it effectively can solve conventional exhaust spool and hold yielding problem, improves the compression efficiency of compressor and increases the service life.
For achieving the above object, the utility model have employed following technological scheme:
A kind of oilless compressor, it is characterized in that: comprise the piston head arranged in cylinder and cylinder, piston head is arranged air inlet spool, the first end of cylinder arranges exhaust plug, the second end of cylinder arranges and is used for ordering about piston head reciprocating driving mechanism in cylinder, exhaust plug comprises first and second valve hole part, wherein: the first valve hole part can fill in cylinder inside cavity when cylinder intake and cylinder inner wall face be sealed and matched, the outside that the second valve hole part is positioned at cylinder is for the installation of exhaust plug on exhaust liquid interface and arrange spring.
In technique scheme, by changing the form that is sealed and matched between exhaust plug and cylinder, what the end end face of exhaust plug can be arranged is less, reduces the possibility that spool is stressed and temperature impact is out of shape, extends the life-span of compressor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete mode of executions of the present utility model, considered critical is not carried out to the protection domain that the utility model is specifically asked.
The technological scheme that the utility model is taked as shown in Figure 1, a kind of oilless compressor, comprise the piston head 12 arranged in cylinder and cylinder 11, piston head 12 is arranged air inlet spool 14, the first end of cylinder 11 arranges exhaust plug 13, the second end of cylinder 11 arranges and is used for ordering about piston head 12 reciprocating driving mechanism in cylinder 11, exhaust plug 13 comprises first, two valve hole parts, wherein: the first valve hole part 131 can fill in cylinder 11 inside cavity when cylinder 11 air inlet and cylinder 11 internal face be sealed and matched, the outside that second valve hole part 132 is positioned at cylinder 11 is for the installation of exhaust plug 13 on exhaust liquid interface 18 and arrange spring.In technique scheme, by changing the form that is sealed and matched between exhaust plug 13 and cylinder 11, what the end end face of exhaust plug 13 can be arranged is less, change and lean on large face to be sealed to the possibility that tapering surrounding stressed sealing reduction spool is stressed and temperature impact is out of shape, extend the life-span of compressor.
Further scheme is, the end cross-sectional of the first valve hole part 131 reduces gradually along first direction, first direction is the direction that exhaust plug 13 points to cylinder 11 side, and the cavity shape of cylinder 11 first end is consistent with the outer contour shape of the first valve hole part 131.The smallest ends end face diameter of the first valve hole part 131 is consistent with the diameter of piston head 12.
Preferred scheme is: the tapering of the first valve hole part 131 is 56 degree, and cylinder 11 first end is arranged to the conical cavity once differed with the first valve hole part 131, and the chamfering angle size of conical cavity is 57 degree.
Concrete operation scheme is: driving mechanism comprises bent axle 15 and installs the crankcase 16 of bent axle, bent axle 15 is connected with piston head 12 by connecting rod 17, cylinder 11 is positioned on crankcase 16, air-breathing spool is arranged in the middle part of piston head 12, cylinder head is positioned on cylinder 11, cylinder head is arranged air inlet liquid interface 19, exhaust liquid interface 18.
Drive motor driving crank running when compressor is opened, bent axle drivening rod operates, connecting rod drives piston head 12 to do back and forth stop motion up and down, the air-breathing spool being arranged in piston head 12 when cylinder 11 internal pressure is greater than inlet pressure when piston head 12 moves toward top dead center from lower dead center is closed (close to allow air-breathing spool exhaust plug 13 usually will be made to add spring-loaded mode make it open pressure to produce pressure reduction higher than normal atmosphere (An) and air-breathing spool and make it close in advance), when when piston head 12 runs toward top dead center, in-cylinder pressure is greater than exhaust plug 13 upper pressure pressure reduction force exhaust plug 13 with piston head 12 up motion exhaust plug 13 open exhaust, just in time fit seamless without residual air or liquid residue in cylinder with exhaust plug 13 when piston head 12 runs to top dead center piston face, when piston head 12 makes exhaust plug 13 close from top dead center toward stop motion pressure reduction, owing to being that plug sealing is gathered in pressure diffusion on exhaust plug 13 and makes its positive confinement to exhaust plug 13 with cylinder body differential seat angle place, the more poorly sealed or blow-by of exhaust plug 13 will be made to reduce compressor efficiency or working life because of deformation, spool continues to make owing to producing the pressure reduction lower than compressor inlet pressure in cylinder, air-breathing spool to be opened toward lower dead center motion at exhaust plug 13 closure piston head 12, piston head 12 moves to lower dead center and completes air-breathing, one time reciprocation cycle completes.
The utility model is the sealing configuration changing exhaust plug 13, optimize gas-liquid discharge capacity, piston head 12 often moves gas-liquid noresidue in a cylinder 11, it is more reliable and stable that compression allows whole exhaust plug 13 seal exhaust liquid more fast, spool is sturdy economical more, and it mainly seals by the tapered angle of spool and casing wall angle of taper, can not because of height pressure reduction during compressor operating, temperature rise, spool end area causes greatly exhaust plug 13 influence of crust deformation efficiency, and working life.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; to know in the utility model after contents; under the prerequisite not departing from the utility model principle; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection domain of the present utility model.
