Abstract
In order to overcome the not enough of the ventilative cap volatile gaseous of current back -fire relief, the utility model discloses an increasing the one -level on back -fire relief ventilative cap upper portion and separating the liquid cap, let in the container volatile gaseous get into the one -level behind the spark arrester and separate liquid cap redirecting, the flow direction connects the liquid cup, and is gaseous along connecing liquid cup inner wall to rise, most gas temperature reduces naturally the back condensation become liquid stay connect the liquid cup in, retrieve in the hole gets back to the container through connecing the inboard liquid of liquid cup, the fraction is gaseous to volatilize from rain -proof cap, guaranteed so promptly the container inside with the atmospheric pressure balance, also reduced the waste of volatilizing of gas.
Description
Technical field
This utility model relates to oil, the safety attachment of chemical industry non-pressure vessel, it can be ensured that the balance of container external and internal pressure, thus ensures the safety of container.
Background technology
The back-fire relief Ventilated cap that non-pressure vessel uses at present is made up of Ventilated cap body, spark arrester, rainhat, when liquid in container volatilization influenced by ambient temperature, the back-fire relief Ventilated cap a large amount of gases of volatilization, cause unnecessary waste, the most inflammable or toxic gas forms destruction to environment after evaporating, it is deposited in container surroundings winter and needs the cleaning of a large amount of human and material resources, also create unsafe factor.
Summary of the invention
In order to overcome the deficiency of existing back-fire relief Ventilated cap volatilization gas, this utility model provides a kind of back-fire relief Ventilated cap, can be reclaimed by back-fire relief Ventilated cap by volatilization gas in non-pressure vessel, reenter in container, it is to avoid waste.
This utility model by increasing one-level oil removal cap on back-fire relief Ventilated cap top, allow volatilization gas in container enter one-level oil removal cap after spark arrester and change direction, the flow direction connects lubricating cup, gas rises along connecing lubricating cup inwall, major part gas temperature is condensed into liquid after naturally reducing and stays and connect in lubricating cup, returns in container by connecing liquid recovery holes inside lubricating cup, and small portion of gas is from rainhat volatilization, the most i.e. ensure that container is internal to balance with atmospheric pressure, decrease the volatilization waste of gas.
Accompanying drawing explanation
Accompanying drawing is vertical section structure figure of the present utility model: 1. back-fire relief Ventilated cap body, 2. spark arrester in figure, 3. connects liquid cup, 4. liquid recovery holes, and 5. one-level is every liquid cap, 6. rainhat, 7. installs screw hole.
Detailed description of the invention
Spark arrester (2) is installed in back-fire relief Ventilated cap body (1) interior bottom in the accompanying drawings, ensure that flame will not enter in container by outside, at upper outlet, screw fixes one-level every liquid cap (5), back-fire relief Ventilated cap body (1) upper extension is interior to one-level oil removal cap (5), one-level forms annular space every liquid cap (5) inner side with back-fire relief Ventilated cap body (1) outside, one-level every liquid cap (5) outside with connect that liquid is cup-shaped circularizes space, connect liquid cup (3) bottom to be casting together with back-fire relief Ventilated cap body (1) middle part, cast above connecting portion connecing lubricating cup (3) with back-fire relief Ventilated cap body (1), have multiple liquid recovery holes (4), rainhat (6) is fixed at the top screw connecing liquid cup (3), during use, liquid recovery back-fire relief Ventilated cap is connected with container by installing screw hole (7).
Claims (3)
1. the liquid that non-pressure vessel uses reclaims a back-fire relief Ventilated cap, and its feature has multiple liquid recovery holes (4), liquid recovery holes (4) through back-fire relief Ventilated cap body (1) on back-fire relief Ventilated cap body (1).
Liquid the most according to claim 1 reclaims back-fire relief Ventilated cap, back-fire relief Ventilated cap body (1) is upper along having one-level every liquid cap (2), one-level forms annular space every liquid cap (2) inwall with back-fire relief Ventilated cap body (1), and one-level forms annular space every liquid cap (2) outer wall with connecing liquid cup inwall.
Liquid the most according to claim 1 and 2 reclaims back-fire relief Ventilated cap, and back-fire relief Ventilated cap body outer wall has liquid to reclaim cup (3), and in the annular space of liquid recovery cup (3), bottom has multiple liquid recovery holes.
