Abstract
The utility model discloses a device of control nitrogen gas pressurized seal bearing seal, the device includes air -vent valve, gas circuit pipeline, and wherein the air -vent valve divide into main pressure regulator valve, terminal air -vent valve, and the main pressure regulator valve is established between main gas circuit pipeline and nitrogen gas source for total pressure of control nitrogen gas, terminal air -vent valve is established respectively on 2~8 branch's gas circuit pipelines being told side by side by main gas circuit pipeline, is used for controlling on branch's gas circuit pipeline speed and pressure that nitrogen gas got into grinding device. In this way, the utility model discloses the device of control nitrogen gas pressurized seal bearing seal has simple structure, convenient operation, can reduce the advantage to the accurate bearing seal device degree of wear.
Description
Technical field
The utility model relates to a kind of device of controlling nitrogen pressure sealing gland seal.
Background technology
In milling apparatus; between machinery face and slurry charge level, there is a set of more accurate gland seal device; in order to keep the pressure at this gland seal device interface corresponding with grinding pressure, simultaneously in order to reduce the friction damage degree of shaft seal, conventionally understand input compressed-air and keep balance. And in the compressed air being provided by air compressor, contain a lot of moisture, even by drying machine process be transported to again equipment use side still have moisture exist, the situation that the compressed air that air compressor provides in addition exists pressure to fluctuate up and down, these all can cause wearing and tearing to a certain degree to gland seal device, reduce service life.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device of controlling nitrogen pressure sealing gland seal for the above-mentioned state of the art, this device can regulate the pressure of supplying nitrogen effectively, keep air pressure relatively stable, reach the effect that reduces wearing and tearing gland seal device.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of device of controlling nitrogen pressure sealing gland seal, be arranged between source nitrogen and milling apparatus, comprise pressure regulator valve, gas path pipe, it is characterized in that: described pressure regulator valve is divided into main pressure regulator valve, end pressure regulator valve, lay respectively on main gas path pipe and branch air path pipeline.
As improvement, described main gas path pipe one end is connected with source nitrogen, and between be provided with main pressure regulator valve, the other end separates 2～8 branch air path pipelines side by side.
Improve, described every branch air path pipeline is connected in corresponding milling apparatus again, and between be provided with an end pressure regulator valve.
Compared with prior art, the utility model has the advantage of: a device of controlling nitrogen pressure sealing gland seal is installed between source nitrogen and milling apparatus, this apparatus structure is simple, easy to operate, can monitor nitrogen flow and speed, the stable pressure being applied in shaft seal of arrival reduces the effect of friction loss.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, a kind of device of controlling nitrogen pressure sealing gland seal, be arranged between source nitrogen 1 and milling apparatus 5, comprise pressure regulator valve, gas path pipe, wherein pressure regulator valve is divided into main pressure regulator valve 2, end pressure regulator valve 4, main pressure regulator valve 2 is located between main gas path pipe 3 and source nitrogen 1, for controlling the stagnation pressure of nitrogen, in addition, four branch air path pipelines 7 that main gas path pipe 3 separates are side by side connected respectively in corresponding milling apparatus 5, and between be provided with an end pressure regulator valve 4, enter speed and the pressure of milling apparatus 5 for controlling nitrogen on branch air path pipeline 7.
When work; first open source nitrogen 1; regulate main pressure regulator valve 2; allow nitrogen enter into respectively four branch air path pipelines 7 by main gas path pipe 3; again according to the grinding situation in each milling apparatus 5; the speed that regulates end pressure regulator valve 4 to control nitrogen is carried out sealing gland seal equipment 6, plays the friction level of protection and reduction shaft seal equipment 6.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (3)
