Description

Mini air compressor pressure regulator

Technical field

The utility model relates to a kind of air compressor, and particularly a kind of controllable motor opens and closes with the gas pressure in the adjusting gas receiver, and the mini air compressor pressure regulator of energy off-load.

Background technique

The purposes of air compressor suitable extensively, for instance, as seen be used for tire in the general daily life or ball inflate or be used for industrial production, so that pressurized gas to be provided.General air compressor has motor, pumping and gas receiver, and motor drive pumping is delivered to gas pressurized in the gas receiver and stored.When gas pressure that the gas pressure in the gas receiver pressurizes greater than pumping, the gas backstreaming in the gas receiver is to pumping, can make the stressed damage of pumping in the running.So can install pressure regulator in the general air compressor, in order to the gas pressure in the detecting gas receiver.When gas pressure that the gas pressure in the gas receiver pressurizes greater than the Pu, pressure regulator control motor shuts down, then pumping stops gas pressurized being sent into gas receiver, make the gas that refluxes directly not impact the pumping in the running, and cooperate Decompression valves to reduce the gas pressure in the gas receiver.

The pressure regulator of existing air compressor includes housing, be provided with in its housing and touch the sensitive switch that sheet, spring and motor join, housing is provided with gas bleeder valve outward, the gas bleeder valve end is extended with compression relief cock, touch sheet one end with respect to sensitive switch, the other end extends the outer compression relief cock with respect to Decompression valves of housing, spring one end and the mutual ejection of inner walls, the other end with touch the mutual ejection of sheet, driving lever extends in the housing by housing and with respect to touching sheet.When gas pressure was excessive in the gas receiver, gas promote to touch sheet, make the elastic force that touches the sheet antagonistic spring and on move and push sensitive switch motor is shut down, touch sheet and push compression relief cock Decompression valves is opened to reduce gas pressure.When gas pressure recovers just often, the strength of spring, and makes motor recover running and closes Decompression valves so promote to touch the sheet returning position greater than gas pressure.Its deficiency is that the reliability of pressure regulator is not high: when the shake-up sheet causes surface abrasion to form bigger surface friction drag because of long-term shift reciprocately, the gas pressure that originally set can't make and touch sheet and have the distance of moving on enough, can cause completely to push sensitive switch and compression relief cock, then can't make motor running also can't open Decompression valves, still make pumping easily cause damage.

For solving the not high problem of reliability of the pressure regulator that has air compressor now, I improve the pressure regulator of air compressor, apply for and obtained utility model patent, and its notification number is: CN2871916Y.Its structure as shown in Figure 1, it comprises body 1, continuous motion stem 2, seal ring 3, switch block and pressure release assembly, body 1 inner hollow, its upper end presses chamber 11, there is pressure release chamber 12 lower end, the connection chamber 13 that communicates with each other is arranged pressing between chamber 11 and the pressure release chamber 12, pressure release chamber 12 has opening end with respect to the other end that connects chamber 13, have on body 1 sidewall with press that chamber 11 communicates first take over 14 be connected second adapter 15 that chamber 13 communicates; Continuous motion stem 2 is arranged in the connection chamber 13 of body 1, and its upper end is stretched on and presses in the chamber 11, and the lower end is stretched in the pressure release chamber 12, and there is the ring flange that radially extends continuous motion stem 2 lower ends; Seal ring 3 is sheathed on outside the continuous motion stem 2; Switch block is located at and is pressed in the chamber 11, and it comprises pad 41, shell fragment 42, loam cake 43, insulating lid 44, permanent joint 45, elastomeric joint 46, elastic conducting strip 461 and push rod 47; The pressure release assembly is located in the pressure release chamber 12, and it comprises end block 51, spring 52, bottom 53, extension tube 54, the collar 55, packing ring 56 and sealing plug 57.The pressure regulator of the air compressor after this improvement makes pumping shut down by promoting elastic conducting strip 461 to form to open circuit, since 461 of elastic conducting strips need fine motion can and contact between form and open circuit, so when gas pressure is excessive in the air reservoir, can both promote shell fragment 42 distortion, thereby the effective and real-time pumping that makes shuts down, and is subjected to the pressure effect of reflux gas and damages with the pumping in avoiding turning round.Simultaneously, shell fragment 42 distortion drive on the continuous motion stem 2 and move, and the extension tube 54 of sealing plug 57 sealings is opened, and reach the pressure release function.Though this utility model patent has solved the not high problem of reliability of the pressure regulator of existing air compressor, its complex structure, the manufacture cost height, and extremely inconvenience is installed, and installing space is too big, and demand merchant is difficult to accept.
