Abstract
A variable-frequency fuel-injection air compressor comprises a case, a wind guide cover is arranged in the case, a cooler is arranged in the wind guide cover, a temperature control valve is arranged at a fuel inlet of the cooler, a temperature measurement probe is arranged in the temperature control valve which is formed by connecting a valve seat and a valve cover, a flat-face flange is arranged on the valve seat, and the temperature control valve is connected at the fuel inlet of the cooler through the flat-face flange. In the utility model, the temperature control valve is directly arranged on the cooler through the flat-face flange, the seepage of the lubricating oil does not easily occur, the piping layout is attractive, the structure of the temperature control valve is compact, and the overall dimension is greatly reduced.
Description
(1) technical field
The utility model relates to a kind of frequency conversion oil spout air compressor.
(2) background technique
Frequency conversion oil spout air compressor is under low temperature environment, particularly under the working state of low frequency running, when temperature is lower than air dew point, moisture content in the pressurized air can be separated, moisture content mixes with lubricant oil, easily causes emulsification of lubricating oils, causes lubrication failure, cause the corrosion of main frame and pipe-line system, thereby the oil spout air compressor all need be at the filler opening place of cooler configuration heat-operated valve.The heat-operated valve that existing market provides adopts three end screw connection structures mostly, and the infiltration that easily produces lubricant oil is assembled also cumbersome.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing frequency conversion oil spout air compressor, the utility model provides a kind of frequency conversion oil spout air compressor that produces the infiltration of lubricant oil easy for installation, difficult.
The technical scheme in the invention for solving the technical problem is: a kind of frequency conversion oil spout air compressor, comprise cabinet, in the described cabinet wind scooper is installed, in the described wind scooper cooler is installed, the filler opening place of described cooler is equipped with heat-operated valve, be provided with temperature probe in the described heat-operated valve, described heat-operated valve is formed by connecting by valve seat and valve gap, described valve seat is provided with face-flange, and described heat-operated valve is connected in the filler opening place of described cooler by described face-flange.
Further, the face-flange of described valve seat is rectangular.
Further, described valve seat is connected by bolt with valve gap.
The beneficial effects of the utility model are: 1. heat-operated valve directly is installed on the cooler by face-flange, is not easy to produce the infiltration of lubricant oil, and piping layout is attractive in appearance.2. the heat-operated valve compact structure has reduced external dimension greatly.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sectional view of heat-operated valve.
Fig. 3 is the structural representation of heat-operated valve.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of frequency conversion oil spout air compressor, comprise cabinet 1, in the described cabinet 1 wind scooper 2 is installed, in the described wind scooper 2 cooler 3 is installed, the filler opening place of described cooler 3 is equipped with heat-operated valve 4, is provided with temperature probe 5 in the described heat-operated valve 4.Described heat-operated valve 4 is formed by connecting by bolt by valve seat 6 and valve gap 7, and described valve seat 6 is provided with the face-flange 8 of rectangle, and described heat-operated valve 4 is connected in the filler opening place of described cooler 3 by described face-flange 8.
Heat-operated valve 4 directly is installed on the cooler 3 by face-flange 8, is not easy to produce the infiltration of lubricant oil, and piping layout is attractive in appearance.The heat-operated valve compact structure has reduced external dimension greatly.
