Description
Technical field
The utility model belongs to air compressor machine technical field, 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, controlling automatic connection by pressure switch when the pressure in gas bag drops to certain numerical value starts, so repeatedly
Start motor to be easy to make motor damage, reduces the service life of air compressor machine.
Invention content
There is provided off-loads a kind of reasonable in design and safe and convenient to use for the technical issues of the utility model solves
Formula air compressor machine.
The utility model adopts the following technical scheme that solve above-mentioned technical problem, relief air compressor, it is characterised in that
It including compression cylinder and is set on compression cylinder and the air inlet communicated with compression cylinder gas chamber and gas outlet, compression cylinder gas
Breather check valve and outgassing nonreturn valve, the air inlet and ambient atmosphere phase are respectively equipped at the air inlet of room and at gas outlet
Logical, air inlet 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, it is described go out
Gas port is communicated with gas bag, and 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, for realizing
The reciprocal operation of piston.
The utility model has the advantages that compared with prior art：The structure design of the utility model is reasonable and uses
Safe ready pushes the piston rod top in off-load cylinder when the pressure in gas bag reaches certain numerical value by the pressure of pressure reducing valve
It drives air valve into, keeps air inlet normally opened, realize automatic deloading, effectively prevent the startup repeatedly of motor, extend air compressor machine
Service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1- compression cylinders, 2- air inlets, the gas outlets 3-, 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 implementation mode
The technical solution of the utility model, relief air compressor, including compression cylinder 1 and setting is described in detail in conjunction with attached drawing
At the air inlet 2 and gas outlet 3 that are communicated on compression cylinder 1 and with 1 gas chamber of compression cylinder, the air inlet of 1 gas chamber of compression cylinder
With breather check valve 4 and outgassing nonreturn valve 5 are respectively equipped at gas outlet, the air inlet 2 is communicated with ambient atmosphere, air inlet 2
It is equipped with 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
It is communicated with gas bag, pressure reducing valve 7 is connected on gas outlet 3, which communicates with the gas chamber of off-load cylinder 6, the compression cylinder
Piston 8 in 1 is connected by toggle 9 with power source 10, for realizing the reciprocal operation of piston 8.
The structure design of the utility model is reasonable and safe and convenient to use, passes through when the pressure in gas bag reaches certain numerical value
The pressure of pressure reducing valve pushes the open-top air intake valve of piston rod in off-load cylinder, keeps air inlet normally opened, realizes automatic deloading, effectively
The startup repeatedly for avoiding motor, extends the service life of air compressor machine.
The basic principle of the utility model, main feature and advantage has been shown and described above, it is new not departing from this practicality
Under the premise of type spirit and scope, the utility model also has various changes and modifications, these changes and improvements both fall within requirement and protect
The scope of the utility model of shield.
