Description
Technical field
A kind of mechanical seal frost-resisting device of the utility model, belongs to equipment protecting equipment technical field.
Background technique
Existing precision instrument generally uses water to carry out cooler envelope as cooling medium, and this machine seal structure is more multiple
Miscellaneous, in winter after equipment out of use, the water inside machine envelope can not discharge completely completely, the phenomenon that being easy to appear icing in winter,
Machine envelope machine machine water shutoff pipeline is easily damaged after icing.
Utility model content
The utility model overcomes the shortcomings of the prior art, and it is simple to provide a kind of structure, easy to use, passes through nitrogen
Gas dryer envelope and machine water shutoff pipeline prevent the defroster of machine envelope damage.
In order to solve the above-mentioned technical problem, a kind of the technical solution adopted in the utility model are as follows: mechanical seal preventing freeze in winter
Device further includes nitrogen storage tank, setting inside nitrogen storage tank including mechanical seal and the machine water shutoff pipeline being connected with mechanical seal
There is heating device, nitrogen storage tank is connected with machine water shutoff pipeline.
The machine seal water pipe road is provided with temperature-detecting device.
The machine seal water pipe road is provided with switch valve.
The nitrogen storage tank is internally provided with temperature control equipment.
The utility model has the advantages that compared with prior art is provided with heating device and temperature in nitrogen storage tank
Spend control device, it can be ensured that reach the requirement of drying into the nitrogen temperature in machine water shutoff pipeline, it is ensured that moisture content in machine envelope
Drying, increases the reliability used, it is ensured that equipment is not in freezing phenomenon in winter.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure 1 be mechanical seal, 2 be machine water shutoff pipeline, 3 be nitrogen storage tank, 4 be heating device, 5 be temperature control dress
It sets, 6 be temperature-detecting device.
Specific embodiment
As shown in Figure 1, a kind of mechanical seal frost-resisting device of the utility model, including mechanical seal 1 and close with machinery
The connected machine water shutoff pipeline 2 of envelope 1, further includes nitrogen storage tank 3, and nitrogen storage tank 3 is internally provided with heating device 4, nitrogen storage tank 3 with
Machine water shutoff pipeline 2 is connected, and temperature-detecting device 6 is provided on machine water shutoff pipeline 2, is provided with switch valve 7 on machine water shutoff pipeline 2,
Nitrogen storage tank 3 is internally provided with temperature control equipment 5.
When the utility model is used, first nitrogen is heated to closing by heating device 4 for before winter equipment downtime
Then nitrogen storage tank 3 is connected with machine water shutoff pipeline 2, dries to machine water shutoff channel interior, pass through temperature by suitable drying temperature
The internal nitrogen temperature of 6 pairs of management of degree control module 5 and temperature-detecting device detects, and increases the reliability of drying.
The embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of various changes can be made.
