Description
Affiliated technical field
The utility model belongs to the pressure switch technical field, refers in particular to a kind of air compressor machine baroswitch.
Background technology
Air compressor machine is widely used in all trades and professions, but its primary structure form is improved little, especially some critical components on it almost never changed, and this must influence the raising of performance of air compressor, just belonged to this situation as the baroswitch on the air compressor machine.That Chinese patent once disclosed was a kind of " the single pressure controller of setting formula " (ZL90202817, stop), form by switch block, bellows pressure sensor, drive block, spring base, spring(-supported) mount, spring, limit base, collar nut etc., adopt bellows pressure sensor to drive the break-make of switch block, so can control the commentaries on classics of compressor stops, but the excessive gas system that does not relate to air compressor machine, if also just say and use it not take other measures that air compressor machine is lost heart, just may be in load condition when restarting.Chinese patent also once disclosed a kind of " air compressor machine baroswitch " (ZL92213905, stop), it comprises base plate, support, gas spring, air pressure adjustment screw, air pressure top, springboard, unloading one-way valve, be positioned on the support of springboard avris manual off-load switch is housed, the miniature A.C. contactor of touch-type also is housed, and its contact is positioned at the springboard top, and it is by manually easily air compressor machine being carried out pressure release at any time.At present, the air compressor machine pressure controller of supplying on the market (air compressor machine baroswitch), its excessive gas system all adopts indirect mode, and design exists the not high defective of pressure release reliability on the structure.Because when cutting off the electricity supply, overbottom pressure in air compressor cylinder and the exhaust large copper pipe is not discharged, then overbottom pressure will be kept the long period in air compressor cylinder and the exhaust large copper pipe, and when people start air compressor machine behind a short time interval, there is certain air pressure toward contact in cylinder and the exhaust large copper pipe, thereby air compressor machine is restarted under the on-load situation, not only strengthen the startup power consumption of air compressor motor, and bigger starting current all can produce harmful effect to motor itself and near electric equipment, shorten air compressor machine useful life, increased maintenance load.The applicant once designed a kind of " automatic pneumatic switch for air compressor " (ZL01220855.8), it comprises switch block, housing, bellows pressure sensor, bellows pressure sensor is contained under the housing, it is characterized in that having a spring support to be contained in the housing, adorn under the spring support springboard, on adorn switch block, housing one side is equipped with unloader, and springboard extends ear under the sealing thimble of unloader.The applicant also provides a kind of " the double automatically manual pneumatic switch of air compressor machine " (ZL01221183.4), it comprises switch block, base plate, bellows pressure sensor, bellows pressure sensor is contained under the base plate, it is characterized in that a control board is contained on the base plate contacts with bellows pressure sensor, place a springboard on this control board, there is its other end of an extension spring to hang on the control board on the springboard, base plate one side is equipped with unloader, springboard extends ear under the sealing thimble of unloader, and the opposite side of base plate has one handle to extend under the springboard.But their outward appearance reputations are also not very good.
The purpose of this utility model is to provide a kind of air compressor machine baroswitch, and it can make the air compressor machine pressure release at any time easily, makes air compressor machine at any time can both be in no load condition, and outward appearance U.S..
For achieving the above object, the solution that the utility model is taked is: a kind of air compressor machine baroswitch, it comprises switch block, shell, bellows pressure sensor, unloading one-way valve, it is characterized in that described bellows pressure sensor is made of diaphragm and sensing head, base and unloading one-way valve are contained under the base plate, base plate has connection jaws, bellows pressure sensor is on base, bellows pressure sensor and transmission mechanism join, switch block and transmission mechanism also are fitted together, transmission mechanism is by spring coupled switch parts, cover shell and being fixed together on the base plate.
Because the utility model is all placed switch block, bellows pressure sensor and transmission mechanism in the enclosure, compares compact conformation, outward appearance U.S. with existing air compressor machine baroswitch.When using the utility model, the air accumulator of air compressor machine communicates with base of the present utility model porch, and the exhaust large copper pipe of the interface of unloading one-way valve and air compressor machine joins.Behind the energize, air compressor machine work, unloading one-way valve compression seal.When air accumulator internal gas pressure during greater than a certain set point (as 12.3kg/cm2), the displacement energy that bellows pressure sensor produces under this pressure condition makes the transmission mechanism action and makes the switch block action power dump, air compressor machine quits work, and has meanwhile opened unloading one-way valve the cylinder of air compressor machine and the pressure in the exhaust large copper pipe are released owing to the effect of transmission mechanism.When the pressure of air accumulator was lower than a certain pressure (as 10.2kgf/cm2), transmission mechanism resetted and switch block is resetted, and power supply is connected automatically, air compressor machine work.The effect of unloading one-way valve can make air compressor machine start under uncharge situation.Therefore; the utility model compared with prior art; when being elevated to a set point or being reduced to a set point, the pressure of the output (air accumulator) of air compressor machine can control stopping or changeing of air compressor machine automatically; protect it not to be damaged; can self-braking the time, shed the overbottom pressure in air compressor cylinder and the exhaust large copper pipe again simultaneously; all be in no load condition when air compressor machine is at any time started reliably, reduce power consumption, prolong air compressor machine useful life.
