Abstract
The utility model relates to an air compressor which comprises a compressor. An air inlet end of the compressor is connected with an air filter and an air inlet valve. An air outlet end of the compressor is connected with an oil gas barrel. A minimum pressure valve is arranged on the top of the oil gas barrel and connected with a gas pipeline. A connecting part is arranged at a butt joint position of the gas pipeline and the minimum pressure valve. A closure valve is arranged at the tail end of the gas pipeline. A gas discharging valve is arranged on the gas pipeline. Due to the fact that the gas discharging valve is arranged on the gas pipeline and a stainless steel ball valve, and thereby potential safety hazard does not exist, disassembling of parts are convenient under the condition of non-pressure, releasing compressed air is convenient, structure is simple, operating is convenient and cost is saved.
Description
Technical field
The utility model is applied to make the air compressor of pressure air.
Background technique
When air compressor being overhauled maintenance; need to shut down and the interior pressure of release pipeline; so that ensure maintenance man's personal safety; but existing air compressor discharges the method for the pressure in the pipeline: at first close this air compressor; then (this gas pipeline is positioned at the air compressor internal body to close the shutoff valve of gas pipeline end; shutoff valve is located at engine body exterior and close body fuselage; be the gas transmission valve of air compressor), dismantle at last the link between the gas pipeline at minimum pressure valve and its rear portion.This link by a seal ring that is enclosed within two adaptor tube outer walls, a pair ofly be clipped in the wafer type clamp of seal ring outside and the locking nut on the clamp forms.In dismounting, need to unclamp first locking nut, clamp and seal ring again come up, when the pressure in the pipeline (about 0.7MPA) bigger than normal, pressurized air is washed very easily suddenly whole link open, so that all parts flies out the maintenance man being caused personal injury, all is that face faces toward link when dismounting especially, and consequence is very serious.
The model utility content
It is a kind of not only safe and reliable but also discharge easily air compressor of pressurized air that its purpose of the utility model provides with regard to being to overcome above defective, have advantages of simple in structure, easy to operate, save cost.
The technological scheme that the utility model is taked to achieve these goals, comprise compressor, described compressor inlet end connects air-strainer and suction valve, described compressor outlet side connects barrel of oil and gas, the barrel of oil and gas top is provided with minimum pressure valve, this minimum pressure valve connecting gas transmission pipe road, and described gas pipeline and minimum pressure valve joint are provided with link, the end of gas pipeline is provided with shutoff valve, and described gas pipeline is provided with drain tap.
Described drain tap is Stainless Steel Ball Valve.
Described drain tap is the DN15 Stainless Steel Ball Valve.
Compared with prior art, the utility model has the advantage of, adopted succinct technological scheme, at described gas pipeline a drain tap is installed, and the drain tap of installing on gas pipeline is Stainless Steel Ball Valve, not only safe and reliable but also release pressurized air makes things convenient for, simple in structure, easy to operate, saving cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the flow chart of the utility model air compressor.
Embodiment
Embodiment, as shown in Figure 1, comprise compressor 3, described compressor 3 inlet ends connect air-strainer 1 and suction valve 2, and described compressor 3 outlet sides connect barrel of oil and gas 4, and barrel of oil and gas 4 tops are provided with minimum pressure valve 5, these minimum pressure valve 5 connecting gas transmission pipe roads 51, described gas pipeline 51 is provided with link 511 with minimum pressure valve 5 joints, and the end of gas pipeline 51 is provided with shutoff valve 52, and described gas pipeline 51 is provided with drain tap 512.
Described drain tap 512 is the DN15 Stainless Steel Ball Valve.
The working principle of the gas system of air compressor: as shown in Figure 1,1, before the start, suction valve 2 full cut-offs, unload and put valve 421 standard-sized sheets.After starting air compressor, air is behind the airborne dust of air-strainer 1 filtering, entering main frame pressing chamber 3 by the micropore on the suction valve 2 compresses, and the lubricant oil with barrel of oil and gas 4 interior sprays mixes, mixing air after the compression enters barrel of oil and gas 4 through gas pipeline 31 again and carries out initial gross separation, and the mixing air after the initial gross separation carries out precision through oil content core 41 again to be separated; 2, when monitoring, just automatically opens when pressure in the barrel of oil and gas 4 reaches 4.5 kilograms the minimum pressure valve 5 on barrel of oil and gas 4 tops, make the air in the barrel of oil and gas 4 deliver to gas pipeline 51, when this moment, the supply gas pressure Sensor monitoring set lower limit (such as 0.6MPA) to the manifold pressure deficiency with signal feed back to control panel, control panel is given signal feed back again and is added/unload solenoid valve (on the suction valve), make it open suction valve 2, just have a large amount of air to enter compressor 3 by air-strainer 1 this moment, so that compressor 3 loads, make a large amount of pressurized air; 3, when the supply gas pressure Sensor monitoring reaches when setting CLV ceiling limit value (such as 0.8MPA) to pipeline 51 internal pressures signal is fed back to control panel again, control panel is given signal feed back again and is added/unload solenoid valve, make it open to unload and put valve 421 and close suction valve 2, this moment, compressor 3 began unloading, stop to make pressurized air, simultaneously, minimum pressure valve 5 is closed, pressure in the barrel of oil and gas 4 through unload put pipe 42 and bleeder valve 421 unload always be put into 4.5 kilograms in addition below, think that next compression cycle prepares; 4, after pressurized air enters pipeline 51 from minimum pressure valve 5, then enter the air-cooled or water-cooled of aftercooler 6() 62 pairs of air of air-cooler cool off, then enter gas holder by gas pipeline 51, until deliver to user side.
The working principle of the oil system of air compressor: air compressor presses off the beginning after starting in system made, and lubricant oil namely begins continuously circulation in compressor 3, barrel of oil and gas 4, return tube 44 and compressor, with lubricated each component.For to the lubricant oil cooling, be provided with thermostat valve 441 and oil cooler 61 at return tube, in order to allow lubricant oil reach desired temperature, guarantee oil, prolong the working life of lubricant oil; Also be equipped with in addition the oil strainer 442 of impurity screening at return tube 44, in addition, in order to remove a small amount of oil in the oil content core 41, add a secondary returning oil pipe 43, this secondary returning oil pipe 43 is provided with an one-way valve 431.
Air compressor is the equipment that precision requirement is very high, needs regularly all parts to be maintained, otherwise can cause adverse consequences to equipment, easily causes damage of components, to reduce the working life of equipment.And air compressor belongs to pressure facility, must stop first air compressor before doing any maintenance and maintenance, then discharges the pressurized air that contains in each pipeline and the volume.Such as: blow down the dust in the air-strainer 1 and change air-strainer 1, add and more oil change, change oil strainer 442 and change oil content core 41 etc.When changing oil content core 41, for maintenance man's personal safety is considered, the utility model improves air compressor, as shown in Figure 1, at gas pipeline 51 drain tap 512 is installed, thus, before changing oil content core 41, close first air compressor and close shutoff valve 52, then just can open drain tap 512 and discharge the gas pipeline 51 interior air with pressure that have, be over Deng the release of compression air, when confirming that barrel of oil and gas 4 internal pressures are zero, dismantle again the link 511 between minimum pressure valve 5 and the gas pipeline 51, dismantle again at last minimum pressure valve 5, so not only do not have potential safety hazard, and the dismounting component are also convenient in the with no pressure situation.
