Description
Technical field
The invention belongs to air compressor machine technical fields, and in particular to a kind of relief air compressor.
Background technology
Air compressor machine is essential infrastructure in industrial production, and the stability of compressor operation directly affects production
The stability of sustainability and product quality.By pressure switch when pressure of traditional air compressor machine in gas bag reaches certain numerical value
Autostop is controlled, is controlled when the pressure in gas bag drops to certain numerical value by pressure switch and connects startup automatically, so repeatedly
Starting motor easily makes motor damage, reduces the service life of air compressor machine.
Invention content
It is empty the technical problem to be solved by the present invention is to provide discharging type a kind of reasonable in design and safe and convenient to use
Press.
It is of the invention to adopt the following technical scheme that solve above-mentioned technical problem, relief air compressor, it is characterised in that including
It compression cylinder and is set on compression cylinder and the air inlet communicated with compression cylinder gas chamber and gas outlet, compression cylinder gas chamber
Breather check valve and outgassing nonreturn valve are respectively equipped at air inlet and at gas outlet, the air inlet is communicated with ambient atmosphere, into
Gas port is equipped with off-load cylinder, and the piston rod in the off-load cylinder is opposite with the movable valve plug of breather check valve, the gas outlet
It is communicated with gas bag, pressure reducing valve is connected on gas outlet, which communicates with the gas chamber of off-load cylinder.
Further preferably, the piston in the compression cylinder is connected by toggle with power source, is used to implement
The reciprocal operation of piston.
The present invention has the advantages that compared with prior art：Side reasonable in design and safe to use of the invention
Just, the open-top air inlet of piston rod in off-load cylinder is pushed by the pressure of pressure reducing valve when the pressure in gas bag reaches certain numerical value
Valve makes air inlet normally opened, realizes automatic deloading, effectively prevents the startup repeatedly of motor, and extend air compressor machine uses the longevity
Life.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：1- compression cylinders, 2- air inlets, 3- gas outlets, 4- breather check valves, 5- outgassing nonreturn valves, 6- off-load gas
Cylinder, 7- pressure reducing valves, 8- pistons, 9- toggles, 10- power sources.
Specific embodiment
With reference to attached drawing detailed description of the present invention technical solution, relief air compressor including compression cylinder 1 and is set to pressure
The air inlet 2 communicated on contracting cylinder 1 and with 1 gas chamber of compression cylinder and gas outlet 3 at the air inlet of 1 gas chamber of compression cylinder and go out
Breather check valve 4 and outgassing nonreturn valve 5 are respectively equipped at gas port, the air inlet 2 is communicated with ambient atmosphere, set on air inlet 2
There is off-load cylinder 6, the piston rod in the off-load cylinder 6 is opposite with the movable valve plug of breather check valve 4, the gas outlet 3 and gas
Packet communicates, and pressure reducing valve 7 is connected on gas outlet 3, which communicates with the gas chamber of off-load cylinder 6, in the compression cylinder 1
Piston 8 be connected by toggle 9 with power source 10, be used to implement the reciprocal operation of piston 8.
The present invention is reasonable in design and safe and convenient to use, passes through decompression when the pressure in gas bag reaches certain numerical value
The pressure of valve pushes the open-top air intake valve of piston rod in off-load cylinder, makes air inlet normally opened, realizes automatic deloading, effectively avoids
The startup repeatedly of motor extends the service life of air compressor machine.
Have been shown and described above the basic principle of the present invention, main feature and advantage, do not depart from spirit of the invention and
Under the premise of range, the present invention also has various changes and modifications, these changes and improvements both fall within claimed invention
Range.
