Description
Technical field
The utility model relates to air compressor valve field more particularly to a kind of reciprocating compressor valve gears.
Background technique
Currently, compressor is mainly by the reciprocating motion of piston so that low pressure gas is collapsed into high pressure gas, wherein air valve is filled
Setting is a significant components.Air-valve device for realizing air suction, row two processes, principle is to be in low pressure in piston cylinder
When, from atmosphere draw air, in piston cylinder high pressure, it is vented to air accumulator.Existing air-valve device is by into and out of the two of stomata
The control of block valve block inhales, arranges two processes.During the work time, valve block is frequently opened and is closed, so that it is between fixed plate
Frequent impact generates very big noise.Valve block receives the active force of alternation at work simultaneously, is easy fatigue rupture, the service life has
Limit.
Utility model content
The utility model is exactly to solve to provide a kind of the noise reciprocating air that the service life is longer can be effectively reduced
Compressor valve device technical problem.
In order to solve the above technical problems, a kind of technical solution of reciprocating compressor valve gear of the utility model
Are as follows:
Including valve fixing seat, inlet valve and exhaust valve；Both the inlet valve, the exhaust valve valve reversed left to right that is fixed on are consolidated
In reservation, the inlet valve and exhaust valve are all air valve；The air valve include upper spring, gas nozzle, sealing sliding block, lower spring with
And end cap；The gas nozzle threaded one end is connected in valve fixing seat, and the other end is threadedly coupled end cap；The gas nozzle middle side edge is opened
There is disengaging air drain；The sealing sliding block, upper spring and lower spring are fixed in gas nozzle by end cap；The sealing sliding block is located at
Between upper spring and lower spring；The sealing sliding block, which can slide up and down, to be connected in sealing sliding block；When resting, described close
Envelope sliding block is located in the middle part of gas nozzle, by disengaging air drain sealing.
The gas nozzle its with valve fixing seat threaded ends be provided with the elastic slot of gas nozzle；It is elastic that the end cap bottom is provided with end cap
Slot.
What the utility model can achieve has the technical effect that the utility model by sealing sliding block to control inlet valve and row
The work of air valve, the lower noise generated, destruction not easy to fatigue, longer life expectancy.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments:
Fig. 1 is a kind of structure sectional view that reciprocating compressor valve gear is total of the utility model；
Fig. 2 is a kind of air valve cross-sectional view of reciprocating compressor valve gear of the utility model；
Fig. 3 is gas nozzle schematic diagram；
Fig. 4 is end cap schematic diagram.
Specific embodiment
Further details of elaboration is made to the utility model with reference to the accompanying drawing.
Refering to fig. 1 to Fig. 4.
A kind of reciprocating compressor valve gear, including valve fixing seat 1, inlet valve 2 and exhaust valve 3；The air-breathing
Both valve 2, exhaust valve 3 are reversed left to right to be fixed in valve fixing seat 1, and the inlet valve 2 and exhaust valve 3 are all air valve；It is described
Air valve includes upper spring 2-1, gas nozzle 2-2, sealing sliding block 2-3, lower spring 2-4 and end cap 2-5；The one end gas nozzle 2-2 spiral shell
Line is connected in valve fixing seat 1, and the other end is threadedly coupled end cap 2-5；The gas nozzle 2-2 middle side edge is provided with disengaging air drain 22；
The sealing sliding block 2-3, upper spring 2-1 and lower spring 2-4 are fixed in gas nozzle 2-2 by end cap 2-5；The sealing sliding block
2-3 is located between upper spring 2-1 and lower spring 2-4；The sealing sliding block 2-3, which can be slided up and down, is connected to sealing sliding block 2-3
It is interior；When resting, the sealing sliding block 2-3 is located in the middle part of gas nozzle 2-2, and disengaging air drain 22 is sealed.
Specifically, the gas nozzle 2-2 its with 1 threaded ends of valve fixing seat be provided with the elastic slot 21 of gas nozzle；The end cap 2-5
Bottom is provided with the elastic slot 51 of end cap；The elastic slot 21 of gas nozzle is with the elastic slot 51 of end cap for facilitating gas nozzle 2-2 and end cap 2-5
Installation and disassembly.
Working principle: the utility model inlet valve 2 and 3 structure of exhaust valve are identical, and installation site is reverse；Valve fixing seat 1
It opens there are two stepped hole, one is used to install inlet valve 2, and, for installing exhaust valve 3, stepped hole includes being relatively large in diameter for another
Unthreaded hole and the diameter threaded hole smaller than unthreaded hole, wherein threaded hole is for being threadedly coupled gas nozzle 2-2；For installing inlet valve 2
Its threaded hole of stepped hole is located at upper end, is located at lower end for installing the stepped hole of exhaust valve 3 its threaded hole.
When the cylinder of air compressor is in low pressure, atmospheric pressure is pressed into the gas nozzle 2- of inlet valve 2 by 2 upper end of inlet valve
In 2 so that inlet valve 2 sealing sliding block 2-3 compression inlet valve 2 lower spring 2-4, at this time the disengaging air drain 22 of inlet valve 2 with
