Background technique
Especially fuel injection screw air compressor in compressor, the compression of air is that a pair of negative and positive rotor by being placed in casing is realized the compression to air in intermeshing rotation by the variation of volume, in air compressing process, a large amount of lubricant oil is injected in compressed air, is mixed in lubricant oil particulate in air Compressor Group is played to lubricated, sealing, cooling and fall low noise effect; The pressurized air of discharging from compressor host relief opening is the mixing air of pressurized air and lubricant oil ultrafine particles composition, the pressurized air that these air-fuel mixture gases need just can be purified by the processing of the gas and oil separating plant of compressor.Existing a kind of gas and oil separating plant, this air separation comprises the oil tank that separates that is provided with suction port and air outlet, described separation oil tank comprises tank body, this tank body is by cylindrical shell and the upper cover and the lower seal head that are welded on described cylindrical shell two ends, described suction port is located at the sidewall of described cylindrical shell, and described air outlet is located at described upper cover top; The suction port of described separation oil tank is connected with the relief opening of compressor host by pipeline, the air outlet of described separation oil tank is connected with the suction port of moisture trap, between described separation oil tank and described moisture trap, by pipeline, minimum pressure valve is housed.In use there are the following problems for this oil-water separation purification device: 1, minimum pressure valve is arranged on the pipeline between oil tank and moisture trap, therefore, the valve assembly of minimum pressure valve must be contained in two ends all to be had on the base of flange mouth, makes the connection mouth of pipeline many and easily occur leakage phenomenon in joint; 2, pipeline is installed loaded down with trivial details and maintenance cost is high; 3, the complex structure of minimum pressure valve, manufacture cost are high.
Model utility content
The problem that the utility model solves is to provide a kind of compressor that minimum pressure valve can be installed at upper cover top and separates oil tank, many and easily occur the problem of leakage at connection mouth place to solve existing separation oil tank and the minimum pressure valve connection mouth by pipeline Placement.
In order to address the above problem, the technical solution adopted in the utility model is: this compressor separates oil tank and includes tank body, described tank body is made up of with the upper end cap that is connected to described cylindrical shell upper end the lower seal head that is welded on cylindrical shell lower end, and described upper end cap has the valve seat on the blind flange that is located at the blind flange of port, described cylindrical shell upper end and be contained in by bolt;
Described valve seat is provided with the dividing plate that has spool positioning hole, the inner space of described tank body is divided into Oil-gas Separation chamber and plenum by described dividing plate, have the valve port and the air outlet that are communicated with described plenum at the top of described valve seat, at described valve port, place is provided with minimum pressure valve.
Above-mentioned compressor separates in oil tank technological scheme, and technological scheme can also be more specifically: the described valve port of described upper cover is coaxial setting with described pressing plate positioning hole;
Described minimum pressure valve there is cylinder body and by pressure mounting of the spring the piston in described cylinder body, the front end of described piston is equipped with sealing clamp, is provided with one section of locating column on described sealing clamp, described locating column clamp with described pressing plate positioning hole on.
Further, be provided with seal ring at the junction surface place of described blind flange and described upper cover, described seal ring is O-ring seals.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: 1, because improve on the top to existing tank body, changing the valve seat that is provided with dividing plate into is connected with cylindrical shell by blind flange, therefore, the inner space of tank body is Oil-gas Separation chamber and plenum by baffle for separating; When work, air-fuel mixture gas after compression enters the Oil-gas Separation chamber of tank body from suction port, indoor through changing direction, turnover in Oil-gas Separation, most oil is separated and is gathered in the bottom of tank body, and the pressurized air that contains a small amount of lubricant oil is fully separated through the olein separator being contained in oil tank; Be gathered on tank body top by the pressurized gas after abundant separating oil, when compression pressure reaches the cracking pressure of minimum pressure valve, pressurized gas backs down the sealing clamp of minimum pressure valve, enter plenum from the spool positioning hole of dividing plate, more finally arrive client end by being contained in the outlet pipe at the upper cover air outlet place moisture trap of flowing through; Because minimum pressure valve is directly installed on the valve seat at tank body top, air pipe is arranged more reasonable, simple, not only save cost but also expanded compressor service space; 2, the leak point of corresponding minimizing pipeline, has reduced rate of fault; 3, minimum pressure valve design becomes more simple, installs more convenient.
