Gas cylinder pipeline one termination at the corresponding levels gas cylinder at the corresponding levels, one-level equilibrium valve one side after another termination, another side joint of back one-level equilibrium valve gas cylinder pipeline at the corresponding levels safety check suction port one side, gas cylinder pipeline safety check at the corresponding levels air outlet one side joint is for the air compressor supply air line; Afterbody gas cylinder pipeline one termination afterbody gas cylinder, suction port one side of another termination afterbody gas cylinder pipeline safety check, the air outlet of afterbody gas cylinder pipeline safety check connects the air compressor supply air line;
The control end one side joint pilot line of equilibrium valve at the corresponding levels is between the gas cylinder of another side joint gas cylinder pipeline at the corresponding levels and back one-level equilibrium valve one side; The control end one side joint pilot line of afterbody equilibrium valve is between the gas cylinder and gas cylinder pipeline safety check of another side joint afterbody gas cylinder pipeline.
Further, described a kind of cascade air feeder, it is characterized in that: on air compressor master supply air line, a two-position three-way valve is set, a two-position three-way valve suction port and an air outlet connect air compressor master supply air line, another air outlet meets of the auxilliary supply air line of air compressor, and the other end of the auxilliary supply air line of air compressor is connected between air compressor supply air line safety check and the reduction valve; Behind the reduction valve with on the air pipe, be provided with throttle valve.
Further, described a kind of cascade air feeder, it is characterized in that: it comprises the level Four gas cylinder.
The pressure (with gas end rated pressure) that the first order is filled bottle gas circuit pressure maintaining valve and reduction valve is identical; The second level is filled bottle gas circuit pressure maintaining valve pressure and is filled a bottle gas circuit pressure maintaining valve greater than the first order; The third level bottle gas circuit pressure maintaining valve pressure that fills backward fills a bottle gas circuit pressure maintaining valve pressure more than or equal to the second level.
Cascade air feeder of the present utility model, its principle is as follows: when air compressor was opened, gas cylinders at different levels were empty, the atmospheric pressure values that fill in bottle pipeline at different levels also are lower than the pressure values that pressure maintaining valve is set in advance, so first order equilibrium valve is opened, bottle gas circuit pressure maintaining valves that fill at different levels cut out.Pressurized air is by air compressor master supply air line, two-position three-way valve, and the air outlet that connects air compressor master supply air line of two-position three-way valve is in opening state, and the air outlet that connects the auxilliary supply air line of air compressor is in closed condition.So pressurized air enters the air compressor steam line along air compressor master steam line and arrives with feed channel to the direct air feed of user by first order equilibrium valve, reduction valve, throttle valve; The atmospheric pressure value before the first order pressure maintaining valve also rises gradually in the first order gas cylinder loading line simultaneously, up to equaling the pressure values that first order gas cylinder loading line pressure maintaining valve is set in advance, pressure maintaining valve is opened then, so pressurized air is inflated to gas cylinder by first order gas cylinder loading line, first order charging check valve, gas cylinder pipeline; By the time after the first order is filled air pressure in bottle gas circuit and is reached the pressure values that second level gas cylinder loading line pressure maintaining valve sets in advance, the second level gas cylinder loading line pressure maintaining valve that is connected with first order gas cylinder loading line is opened, begin to the inflation of second level gas cylinder, the rest may be inferred by analogy, is full of gas until all gas cylinders.
When each gas cylinder outwards is full of behind the gas air feed, earlier by the afterbody gas cylinder by gas cylinder pipeline, supply air line, reduction valve, throttle valve, with air pipe to user's air feed; Along with air feed, the pressure of afterbody gas cylinder and gas cylinder pipeline descends gradually, also is that the pressure of a side of afterbody equilibrium valve control end descends gradually.When pressure drops to, with opposite side also is that the pressure of pilot line is when adding that pressure that the heavy elastic component of equilibrium valve produces equates, the afterbody equilibrium valve is opened, and the pressure of afterbody gas cylinder is reduced to air feed no longer behind the pressure of air pipe, so the penultimate stage gas cylinder begins air feed (these three steps take place simultaneously).The rest may be inferred by analogy opens until first order equilibrium valve, and air compressor is by air compressor master supply air line, supply air line, directly to user's air feed; Drop to can not be more externally air feed the time etc. first order gas cylinder pressure, next round gas cylinder inflation beginning.
When air compressor supply air line and first order gas cylinder loading line can not gas transmissions, can utilize the auxilliary supply air line of two-position three-way valve and air compressor directly to give user's air feed.
Effective airdelivery rate height of the present utility model.The utility model has realized that air compressor is preferentially set up maximum pressure to the gas cylinder tonifying Qi time and cascade is set up storage pressure, preferentially enables in the minimum pressure gas cylinder air and enable air in other gas cylinder in proper order according to the pressure cascade when outside output gas.
On one's own time all gas cylinders all are filled into setting pressure, native system can come out the gas release that stores in the gas cylinder to greatest extent in the operating time, be equivalent to improve the air demand of system, so just need not to adopt the compressor of big flow, the compressor of small flow+stage air feeder described in the utility model just can satisfy the demand of gas consumption.The gas cylinder of existing air supply system can only play a buffer function, perhaps can only discharge fraction gas and be used the gas end, so its traffic requirement to compressor will strengthen.
Require (the no non-working time is used for the gas cylinder tonifying Qi) at stablizing air feed for a long time, application value of the present utility model is little.
In addition,, utilize the time spread of electric power, can effectively reduce the power cost of air compressor in the operational site that the electric power price difference is arranged.As: non-working time at night, electricity price is lower, gas cylinder all is filled into setting pressure, to the time electricity price that works by day higher, because the utility model can gas release come out gas cylinder to greatest extent, so can utilize the gas that stores evening to greatest extent, reach the purpose that cuts operating costs.
The utility model biggest advantage is, by the flow direction control to gas, gives the user with the effective gas priority of supply.The preferential build-up pressure difference of the utility model is so that with gas (have pressure difference could toward outside air feed).
Existing air supply system does not have any control to tonifying Qi is to carry out simultaneously and with pipeline with gas with to gas cylinder to the flow direction of gas.
