Abstract
The invention discloses a dry gas seal and supply device for a compressor, belonging to the technical field of dry gas seal of compressors and aiming at providing the dry gas seal and supply device which can use medium-pressure nitrogen gas and interruptedly supply gas so as to improve the utilization rate of medium-pressure nitrogen gas. The invention adopts the technical scheme that a low-pressure nitrogen gas storage tank is communicated with a unit seal through a first pipeline, wherein a first check valve and a first manual valve are sequentially arranged on the first pipeline; the first pipeline between the first manual valve and the unit seal is communicated with the medium-pressure storage tank through a second pipeline; a second manual valve, a self-operated pressure regulating valve, a third manual valve, a second check valve and a fourth manual valve are sequentially arranged at one end, which is close to the medium-pressure nitrogen gas tank, of the second pipeline; the second pipeline between the third manual valve and the second check valve is communicated with the medium-pressure nitrogen gas tank through a third pipeline; and a fifth manual valve is arranged on the third pipeline. The dry gas seal and supply device disclosed by the invention is mainly used for gas supply of dry gas seal of the compressor.
Description
Technical field
Compressor dry gas seals air feeder of the present invention belongs to compressor dry gas seals technical field.
Background technique
Because the compressor dry gas seals has strict demand to the sealing nitrogen pressure, only use the low-pressure nitrogen air feed, following shortcoming is arranged: one, when supply air line damage or source of the gas deficiency, need to change gas holder, at this moment just must close whole supply air line, make the compressor interruption of work; Two, medium pressure nitrogen gas transfers first low-pressure nitrogen to, again to low-pressure nitrogen pipe network air feed, makes nitrogen emptying amount can not get greatly effective recovery, wastes larger.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of compressor dry gas seals air feeder that can use medium pressure nitrogen gas, also uninterrupted air feed, improves the utilization ratio of medium pressure nitrogen gas.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: compressor dry gas seals air feeder, comprise the unit sealing, low-pressure nitrogen storage tank and medium pressure nitrogen gas storage tank, low-pressure nitrogen storage tank and unit sealing are by the first pipeline connection, the first safety check and the first manually operated valve are installed on the first pipeline successively, be communicated with the medium pressure nitrogen gas storage tank by the second pipeline on the first pipeline between the first manually operated valve and the unit sealing, the end near the medium pressure nitrogen gas storage tank on described the second pipeline is equipped with the second manually operated valve successively, self-contained pressure regulator, the 3rd manually operated valve, the second safety check and the 4th manually operated valve.
The second pipeline between described the 3rd manually operated valve and the second safety check is communicated with the medium pressure nitrogen gas storage tank by the 3rd pipeline, on described the 3rd pipeline the 5th manually operated valve is installed.
The present invention compares the beneficial effect that has with prior art: the present invention has increased a medium pressure nitrogen gas supply air line on original low-pressure nitrogen air feed basis, and be provided with self-contained pressure regulator at pipeline, directly medium pressure nitrogen gas is depressured to after the standard for sealing, has improved the utilization ratio of medium pressure nitrogen gas; The use of many pipelines can not interrupted because of the damage of self-contained pressure regulator the work of compressor, has improved safety guarantee.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Among the figure: 1 is the unit sealing, and 2 is the low-pressure nitrogen storage tank, and 3 is the medium pressure nitrogen gas storage tank, 4 is the first pipeline, and 5 is the first safety check, and 6 is the first manually operated valve, 7 is the second pipeline, 8 is the second manually operated valve, and 9 is self-contained pressure regulator, and 10 is the 3rd manually operated valve, 11 is the second safety check, 12 is the 4th manually operated valve, and 13 is the 3rd pipeline, and 14 is the 5th manually operated valve.
Embodiment
As shown in Figure 1, compressor dry gas seals air feeder of the present invention, comprise unit sealing 1, low-pressure nitrogen storage tank 2 and medium pressure nitrogen gas storage tank 3, low-pressure nitrogen storage tank and unit sealing 1 is communicated with by the first pipeline 4, the first safety check 5 and the first manually operated valve 6 are installed on the first pipeline 4 successively, be communicated with medium pressure nitrogen gas storage tank 3 by the second pipeline 7 on the first pipeline 4 between the first manually operated valve 6 and the unit sealing 1, the end near medium pressure nitrogen gas storage tank 3 on described the second pipeline 7 is equipped with the second manually operated valve 8 successively, self-contained pressure regulator 9, the 3rd manually operated valve 10, the second safety check 11 and the 4th manually operated valve 12.
The second pipeline 7 between described the 3rd manually operated valve 10 and the second safety check 11 is communicated with medium pressure nitrogen gas storage tank 3 by the 3rd pipeline 13, on described the 3rd pipeline 13 the 5th manually operated valve 14 is installed.
On the second pipeline 7 before the second manually operated valve 8 and the 3rd manually operated valve 10 is rear that an on-the-spot pressure gauge all is installed, so that the field monitoring pipeline inner pressure.
Safety check is that open-shut device leans on the strength of media flow to open voluntarily or close, with the valve that prevents that medium from flowing backwards.Safety check belongs to the self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction.
Self-contained pressure regulator according to pressure point position minute valve before and two classes behind the valve, pressure point is used for the front constant pressure of modulating valve before valve the time; Pressure point is behind valve the time, is used for constant pressure behind the modulating valve, and self-contained pressure regulator 9 pressure points are behind valve among the present invention.
When the present invention works, the first manually operated valve 6 and the 5th manually operated valve 14 are in closed condition, medium pressure nitrogen gas in the medium pressure nitrogen gas storage tank 3 is by the second pipeline 7, after the second manually operated valve 8, self-contained pressure regulator 9 and 10 step-downs of the 3rd manually operated valve, flow through the second safety check 11 and the 4th manually operated valve 12 enter in the unit sealing 1;
When self-contained pressure regulator 9 damages, open the 5th manually operated valve 14, close the second manually operated valve 8 and the 3rd manually operated valve 10, the pressure of the 5th manually operated valve 14 is adjusted to the required nitrogen pressure of pipe network, enter into the second pipeline 7 after making medium pressure nitrogen gas by the 5th manually operated valve 14 step-downs on the 3rd pipeline 13, and enter unit sealing 1 through the second safety check 11 and the 4th manually operated valve 12, simultaneously self-contained pressure regulator 9 is keeped in repair, the manually operated valve of opening again on the second pipeline 7 after maintenance is finished is enabled the second pipeline 7 air feed; Close the 5th manually operated valve 14.
When the second pipeline 7 and the 3rd pipeline 13 all can't use, or the medium pressure nitrogen in the medium pressure nitrogen gas storage tank 3 is run out of air, during the medium pressure nitrogen gas storage tank 3 that need to more renew, open the first manually operated valve 6, enable the first pipeline 4 and carry out the low-pressure nitrogen air feed, close all manually operated valves on the second pipeline 7 and the 3rd pipeline 13; When recovering normal, the second pipeline 7 uses or medium pressure nitrogen gas storage tank 3 is changed and again made the second pipeline 7 recover to use after complete.
