Description
Technical field
The utility model relates to the petrochemical equipment technical field, specifically, relates to a kind of back-fire relief respirator that is installed on the oil storage tank.
Background technology
Mostly the product of petrochemical enterprise is flammable liquid, and these flammable liquids adopt jar kind equipment to store usually, and wherein a large amount of uses is oil storage tank.For the safety of producing and storing, traditional way is on the top of oil storage tank spark arrester and breather valve to be installed respectively.The effect that spark arrester is installed is: prevent fuel gas when discharging, run into ignition substance such as thunder and lightning, outside burning things which may cause a fire disaster, static etc. cause burning or introduce jar in and the accident of blasting.The effect that breather valve is installed is: oil storage tank produces the phenomenon of gas turnover oil storage tank in charging or discharging, thermal expansion meeting when medium runs into heating, cooling, is provided with silk screen and pressure-activated device owing in the breather valve, thus the security when having guaranteed exhaust.
Because the manufacturer of the finished product spark arrester of being purchased is more random, often occurs the malfunctioning problem of spark arrester in the actual production; Cause winter occurring the phenomenon that the breather valve blast pipe is stopped up in the moisture frosting owing to containing micro-moisture in the oil product, make oil product have very big potential safety hazard.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of back-fire relief effective, storage security, ventilatory effect is good, winter frost-free oil storage tank back-fire relief respirator.
For solving the problems of the technologies described above, the technical scheme of the utility model is: oil storage tank back-fire relief respirator comprises: tubular shell is provided with some passages near the barrel of first end of said tubular shell; Woven wire, said woven wire are wrapped on the outer wall corresponding to said passage of said tubular shell; Protective cover, said protective cover cover is buckled in first end of said tubular shell, and is fixedly connected with said tubular shell is removable; The back-fire relief back-up ring, said back-fire relief back-up ring is arranged on the outer wall of said tubular shell, and between said protective cover and tubular shell, said back-fire relief back-up ring is provided with some through holes.
As preferably, said woven wire is a 40-60 purpose stainless steel cloth, and said stainless steel cloth is provided with multilayer.
As preferably, said passage is the axially extended slotted hole along said tubular shell.
As preferably, said protective cover is the little pyramidal structure of the big other end of an end.
As preferably, second end of said tubular shell is provided with flange.
Owing to adopted technique scheme, the beneficial effect of the utility model is: because the oil storage tank back-fire relief respirator of the utility model comprises: barrel is provided with the tubular shell of some passages; Be wrapped in the woven wire at said passage place; Cover is buckled in the protective cover of said tubular shell end; Back-fire relief back-up ring between said protective cover and tubular shell.Make this oil storage tank back-fire relief respirator possess the dual-use function of spark arrester and breather valve, during use, this oil storage tank back-fire relief respirator is installed in the top of oil storage tank.Woven wire wherein and back-fire relief back-up ring are the main members that stops flame propagation, and the fine and closely woven mesh of woven wire also plays the effect of breathing.Therefore, effective, the oil product storage security of this oil storage tank back-fire relief respirator back-fire relief, ventilatory effect is good, winter frost-free.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Accompanying drawing is the structure cross-sectional schematic of the utility model embodiment;
Among the figure: the 1-protective cover; 2-back-fire relief back-up ring; The 21-through hole; The 3-tubular shell; The 31-passage; The 4-flange; The 5-pipe clamp; The 6-woven wire.
