Description
Technical field
The utility model relates to a kind of air compressor, and particularly a kind of controllable motor opens and closes to regulate the air compressor novel pressure controlling device of the gas pressure in the gas receiver.
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 factory, 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 pumping, 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 the sensitive switch that touches sheet, spring and join in its housing with motor, 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 is excessive in the gas receiver, gas promote to touch the sheet antagonistic spring elastic force and on move and push sensitive switch and make motor shut down, touch sheet to push compression relief cock Decompression valves is opened to reduce 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 nationality of this air compressor that has improved 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, the pumping that makes that all can be effective and real-time shuts down, and is subjected to the pressure effect of reflux gas and damages with the pumping in avoiding turning round.Simultaneously, move on the distortion drive continuous motion stem 2 of nationality by shell fragment 42, the extension tube 54 of sealing plug 57 sealings is opened, reach the function of pressure release.Though this utility model patent has solved the not high problem of reliability of the pressure regulator of existing air compressor, its complex structure, fabricating cost height.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and provide a kind of air compressor novel pressure controlling device, so that motor is in time shut down, release pumping simultaneously to the interior residual gas of pipe between the one-way valve, do not open pressure in can not producing when motor is turned round once more and damage pumping and motor, and simple in structure, fabricating cost is low.
The technical solution of the utility model is: a kind of air compressor novel pressure controlling device, it comprises body, continuous motion stem, seal ring and switch block, body interior hollow, its upper end presses chamber, there is the pressure release chamber lower end, the connection chamber that communicates with each other is arranged pressing between chamber and the pressure release chamber, the pressure release chamber has second to take over respect to the other end that connects chamber, have on the body sidewall with press first adapter that chamber communicates be connected the exhaust port that chamber communicates; Continuous motion stem is arranged in the connection chamber of body, and its upper end is stretched on and presses in the chamber, and the lower end is stretched in the pressure release chamber, and there is sealing plug the continuous motion stem lower end, and pressure-releasing chamber is indoor seal ring; Seal ring is sheathed on outside the continuous motion stem; Switch block is located at and is pressed in the chamber.
The further technological scheme of the utility model is: also comprise manual compression relief cock, axis hole is arranged on the sealing plug, manually compression relief cock is an eccentric shaft, and it is installed in the axis hole on the sealing plug.
The utility model more further technological scheme be: the sealing plug lower end be shaped as up big and down small taper shape, the sealing surface of seal ring be shaped as the up big and down small taper shape that the shape with the sealing plug lower end adapts.
The utility model further technological scheme is: jagged on relative second face of taking on the seal ring, so that when the gas that flows into second adapter flowed in the pressure-releasing chamber chamber, the pressure that can utilize gas was with the clearance seal between sealing plug and the seal ring.
Characteristics such as the utility model compared with prior art, has pressure controlled reliability height owing to adopt as above design, and is simple in structure, and fabricating cost is low.But also manual compression relief cock can be installed, when motor driven pumping running, and when the gas pressure in the air reservoir is not enough to the shell fragment distortion of pushing switch assembly, also can open manual compression relief cock as required easily and release pumping residual gas to the pipe between the one-way valve, a pressure in when starting motor once more, can not producing and damage pumping and motor.
