Description
Technical field
The utility model is related to fracturing device fields, and in particular to a kind of automatic vent type fracturing device.
Background technology
Carbon dioxide fracturing device is using liquid carbon dioxide by thermal evaporation expansion that quick release gases at high pressure are disrumpent feelings rock
Or coal breakage, the shortcomings of blowing high destructive big and danger in exploitation, presplitting, ore body crushing up with dynamite in the past is overcome, is ore deposit
Mountain safe working and presplitting provide reliable guarantee, are widely used in colliery and non-coal mine.
Existing carbon dioxide fracturing device is before use, it will usually carbon dioxide liquid of first substituting the bad for the good, but in storage, outside
The temperature on boundary is can be changed, and after ambient temperature changes, the air pressure in carbon dioxide fracturing device liquid storage pipe also can
It changes, after the air pressure in carbon dioxide fracturing device liquid storage pipe raises, if cannot be timely by carbon dioxide fracturing device
Excessive gas discharge in liquid storage pipe, then be possible to the risk for being present with bombing, generally use is one in the prior art
Body formula needle-valve, to be exhausted, i.e., when the air pressure in liquid storage pipe is excessively high, extra gas just can be by integral type pin in liquid storage pipe
The shortcomings that tight fixed bolt punching of valve falls, and is depressured so as to achieve the effect that be vented, but such is that coming off for tight fixed bolt is not
It oneself can reinstall, that is to say, that cause the carbon dioxide in liquid storage pipe that can not also be closed when air pressure drops to safety value, once
Tight fixed bolt punching is fallen to may result in the gas in liquid storage pipe and be all released, so use carbon dioxide fracturing device into
Before row fracturing, it is necessary to gas progress filling again, will like this increase cost, while existing carbon dioxide
Once fracturing device preponderance, when being moved using draw ring to it, draw ring is easy for coming off, and jam nut is also inconvenient
In installation.
