Abstract
The utility model discloses an automatic blow down device of high pressure air. The automatic blow down device comprises a ventilating valve, wherein the upper end of the ventilating valve is connected with a high-pressure pipeline, the lower end of the ventilating valve is connected with a drain outlet, a blot air inlet is connected with the inside of the ventilating valve, and the high-pressure pipeline is connected with a solenoid valve and a high-pressure air source. The automatic blow down device of high pressure air is novel in design, simple in structure and obvious in effect, does not need manual operation, is convenient, reliable and small in system size and can be reasonably placed according to actual conditions, and the sewage accumulating time and the automatic discharging time are automatically controlled by a programmable logic controller (PLC).
Description
Technical field
The utility model relates to a kind of drainage device, and what be specifically related to is the high-pressure air automatic sewage discharging device.
Background technique
In metallurgical process instrument gas pressure measurement, because the impure and moisture of medium can cause the accumulation of moisture and impurity usually, cause measuring and forbidden, cause control deviation, influence control accuracy.Common solution be artificial blowdown after a while once, though this has solved the accumulation of moisture and impurity, labor intensive and material resources.Therefore, we press for a kind of drainage device that can get rid of moisture and impurity accumulation automatically.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and the high-pressure air automatic sewage discharging device is provided, and need not manual operation, can automatic pollution discharge.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
The high-pressure air automatic sewage discharging device comprises ventilation valve, and described ventilation valve upper end connects pressure duct, and described ventilation valve lower end connects the inner spot suction port that connects of the described ventilation valve of sewage draining exit, and described pressure duct connects solenoid valve and high-pressure air source.
Further, described ventilation valve comprises body, and described body upper end is provided with loam cake, and described body lower end is provided with lower cover, and described body center is provided with spool, and described body connects the profit suction port.
The beneficial effects of the utility model are:
The utility model modern design, simple in structure, effect is obvious, and sewage accumulates the time and automatic drain time is all controlled automatically by PLC, need not manual operation, and is convenient and reliable.System bulk is little, can rationally put according to actual conditions.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to Fig. 1, shown in Figure 2, the high-pressure air automatic sewage discharging device comprises ventilation valve 3, and described ventilation valve 3 upper ends connect pressure duct 1, described ventilation valve 3 lower ends connect the sewage draining exit 5 described ventilation valve 3 inner spot suction ports 4 that connect, and described pressure duct 1 connects solenoid valve 2 and high-pressure air source 6.
Further, described ventilation valve 3 comprises body 9, and described body 9 upper ends are provided with loam cake 7, and described body 9 lower ends are provided with lower cover 11, and described body 9 centers are provided with spool 8, and described body 9 connects profit suction port 10.
Principle of the present utility model;
Described solenoid valve 2 gets electric opening, and pressurized gas enter in the described ventilation valve 3, push down its spool, make described sewage draining exit 5 close, and sewage must not be got rid of.After sewage is accumulated a period of time, to be closed by described solenoid valve 2 dead electricity of PLC control, described high-pressure air source 6 is cut off, and the spool 8 of described ventilation valve 3 automatically restores to the free state position under the work of spring force, and described sewage draining exit 5 is opened, and sewage is discharged.
