Abstract
The utility model relates to an automatic control valve for an air compressor. When the air pressure in an air compressor is surplus, the air compressor is still at work, the surplus gas can be expelled form a safety valve, and waste can be caused. The automatic control valve of the utility model can overcome the defects, which is characterized in that a gas bag, a self lock device and a spring control valve are adopted to realize the self control task, when the air pressure in the air compressor is surplus, the air compressor can rotate idly, the air pressure in an air cylinder can be controlled in a limited range, the automatic control valve of the utility model is composed of a valve assembly arranged in the valve body (1), a slide valve assembly, a self lock device, a one-way valve and valve body attachments. The utility model has the advantages of energy saving and long service life.
Description
The utility model is a kind of internally piloted valve, and it matches with existing air compressor, and the air pressure that is used for controlling in the gas receiver keeps within the specific limits, removing unnecessary gas from discharges from safety valve, cause unnecessary waste, and increase the weight of the burden of air compressor, shorten the spreadable life.
Domestic at present, as to have produced automobile-used air compressor has been installed the auto-controlled clutch from 92 years except that Dongfeng Automobile, and all automobile-used air compressors all are to synchronous working with power, and unnecessary air is discharged from safety valve, causes waste.Present this vehicle recoverable amount at home also has millions of, and social loss is very big.The air press that factories and miness are used is controlled the air inflow of air compressor at valve by the control of gas receiver air pressure of air-strainer place installation after the seventies, the air pressure and the air inflow of gas receiver are inversely proportional to, when the air pressure in gas receiver reaches regulation air pressure, the valve Close All, air compressor stops air inlet, air compressor is worked under sulks, and can not do fully loads reaches the purpose of idle running.
At the problem of above-mentioned existence, the utility model has designed a kind of air compressor internally piloted valve that can guarantee that air compressor is worked in certain supply gas pressure scope.And can make air compressor under the highpressure of regulation, be in idle running, reach air compressor and do the purpose of loading fully.
The purpose of this utility model is achieved in that its method is: finish the automatic control task by air bag, self-locking device and spring controlled valve.It is made up of valve body assembly, valve assembly, Scotch yoke, self-locking device and one-way valve.Valve body assembly has valve body, Sealing, plug screw, connector screw.Valve assembly has valve, spring, nut, steel ball.Scotch yoke has guiding valve, plug screw, pad, spring, air bag, gas to chew core.Self-locking device has pad, plug screw, spring, steel ball.One-way valve has spring, valve block.
The utility model compared with prior art, its advantage is: (1) not only can make air compressor idle running, and can guarantee in the gas receiver air pressure within the specific limits.(2) be member independently, needn't change existing air compressor.(3) the energy loss-rate existing control air inlet of industrial and mineral type is few.
Description of drawings:
Shown in the figure, (1) is valve body, and (2) are valves, (3), (9), (12), (20) are springs, (4), (7) are plug screws, (5), (13) they are steel balls, (6) be guiding valve, (8), (10) be pad, (11) are nuts, (14) are air bags, (15) be that gas is chewed core, (16), (18) be Sealing, (19) are connector screws, (21) are valve blocks.
The utility model one of is implemented, as shown in the figure, further specify below in conjunction with accompanying drawing: valve body (1) has the hole of air flue A, B, C and mounted valve assembly Scotch yoke, self-locking device, one-way valve, and valve assembly, Scotch yoke, self-locking device, one-way valve are installed in wherein.Air flue A one end communicates with air compressor, and the other end leads to gas receiver through one-way valve, connector screw (19).Air flue B one end communicates with air flue A, and the other end leads to air bag (14).Air flue C is led to the seat hole of valve (2) by atmosphere.Guiding valve (6) one sides of Scotch yoke have pit I to be used for matching with steel ball (5) in the valve assembly, the effect of playing the pass, opening valve, opposite side has two pit II III to be used for matching with steel ball (12) in the self-locking device, and the air pressure that is used for keeping in the gas receiver has certain pressure difference.Spring (9) and the power of air bag (14) as promotion guiding valve (6).Air bag (14) has a gas to chew.Be enclosed within gas and chew on the core (15), and be pressed in the valve body (1) with plug screw (17).One-way valve is that the control air-flow only can enter gas receiver from air compressor, can not flow backwards.
Two of the utility model enforcement: because the air pressure that the utility model can be kept in the gas receiver has bigger pressure reduction, so the air pressure in gas receiver is in down in limited time, valve (2) is closed.This falls in the pit I of sliding (6) the steel ball in the valve assembly (5), and the steel ball in the self-locking device (13) falls in the pit II of guiding valve (6).The air that comes from air compressor one the tunnel enters gas receiver behind air flue A, one-way valve, the one tunnel enters air bag (14) through air flue B.Air pressure increase along with gas receiver, the air pressure of air bag (14) also increases, overcoming spring (9) and self-locking device until its pressure, to be added in the resistance of guiding valve (6) right, guiding valve (6) moves to spring (9) one sides, steel ball (5) and (13) are pushed out pit I and II, at this moment the resistance of guiding valve (6) significantly reduces, spring (9) is compressed, laid in potential energy, till steel ball (13) falls into the III hole, after steel ball (5) leaves the I hole, spring (3) is compressed, valve (2) is opened, and or else the air-flow that comes from air compressor then enters gas receiver, but enters atmosphere from air flue C.
Three of the utility model enforcement: along with the decline of gas receiver air pressure air compressor idle running, the air pressure of air bag (14) also descends, pressure until gas receiver drops in limited time, the air pressure of air bag (14) also drops to lower limit, the potential energy that the spring (9) that has been compressed is laid in can overcome the resistance that self-locking device is added in guiding valve (6), steel ball (13) is pushed out pit III, the suffered resistance of guiding valve (6) significantly reduces, guiding valve moves till steel ball (5) and (13) fall into pit I and II to air bag (14) end, valve this moment (2) is closed at following air flue C that leads to atmosphere of the effect of spring (3), the gas that comes from air compressor enters gas receiver through one-way valve, the effect of automatic control is played in air compressor work.Guarantee the interior air pressure of gas receiver within certain scope, energy saving, life-saving.
