Abstract
The utility model provides a kind of liquid cargo system of chemical tanker blow-line purging device, specifically includes：The liquid goods pipe that one end is provided with blowing-down device adpting flange is fastened by bolt with offset hole flange, and the minimum point of offset hole flange institute perforate is concordant with liquid goods inside pipe wall bottom；Offset hole flange aperture correspondence welding blow-off pipe, the bottom for blowing down inside pipe wall is concordant with the bottom of liquid goods inside pipe wall；The other end of blow-off pipe is connected by welding the standard flange of center drilling with blow through valve；Blow through valve connection end is provided with the snap joint of standard flange.The utility model is used for during the blowing of the liquid goods pipe of chemical tanker, on the one hand, solve the problems, such as that liquid goods pipe blows down effect on driving birds is not good, kinds of goods and wastes, on the other hand effectively reduce residual volume in liquid goods pipe, reduction and put residual workload, the risk for reducing crewman's workload, reducing chemical tanker liquid goods blowdown environmental pollution manually.
Description
Technical field
The utility model is related to Ship Design and building technology field, more specifically to a kind of chemical tanker liquid goods
System pipeline blowing-down device.
Background technology
Chemical tanker needs to carry out blowing treatment to liquid goods pipeline after routinely unloading, is remained at least with reaching in liquid goods pipeline
The purpose of kinds of goods.Blow down treatment is usually carried out to liquid using compressed air on ship or nitrogen pipeline connection Ye Huo blow-line purgings valve
Goods pipe is blown down.
Prior art is the blowing-down device of liquid goods Guan Shangwu specially treateds, only sets branch pipe in liquid goods bottom of the tube position, even
Connect blow through valve.On the one hand blowing effect is undesirable for this kind of design, on the other hand easy in the blowing branch pipe of liquid goods bottom of the tube setting
Remaining kinds of goods, crewman need to manually be put residual treatment to branch pipe position herein, it has not been convenient to which crewman operates, and put residual in treatment
During increase put pollution of the shopworn goods product to marine environment.
The content of the invention
Deficiency of the utility model for the existing blowing-down device of above-mentioned chemical tanker, there is provided a kind of to be easy to what crewman operated
Liquid cargo system of chemical tanker blow-line purging device.
The utility model solution is specifically included：The liquid goods pipe that one end is provided with blowing-down device adpting flange passes through bolt
Fastened with offset hole flange, the minimum point of offset hole flange institute perforate is concordant with liquid goods inside pipe wall bottom；
In offset hole flange aperture correspondence welding blow-off pipe, the bottom of the blowing inside pipe wall and the liquid goods pipe
The bottom of wall is concordant；
The other end of the blow-off pipe is connected by welding the standard flange of center drilling with blow through valve；The blow through valve connects
Connect the snap joint that end is provided with the standard flange；
Pad is set between the blowing-down device adpting flange and offset hole flange；
Pad is set between the snap joint of the standard flange and the blow through valve.
Under preferred embodiment, radius of the blow-off pipe caliber less than or equal to the liquid goods pipe.
Under preferred embodiment, the pad is teflon gasket.
Compared to prior art, the utility model has the advantage of：
1st, the utility model blow-off pipe position (inwall low spot is concordant with by blowing liquid goods inside pipe wall bottom) and caliber set
Meter can reach the purpose for effectively blowing down residual kinds of goods in liquid goods pipeline.
2nd, the utility model used unit is standard component, and process is simple, low cost.
3rd, the utility model is used for during the blowing of the liquid goods pipe of chemical tanker, on the one hand, solve the blowing of liquid goods pipe
The problem that effect on driving birds is not good, kinds of goods are wasted, on the other hand effectively reduces residual volume in liquid goods pipe, reduction and puts residual workload manually, subtracts
Few crewman's workload, the risk for reducing chemical tanker liquid goods blowdown environmental pollution.
Brief description of the drawings
Fig. 1 is a kind of special blowing-down device of chemical tanker.
Fig. 2 is special blowing-down device offset hole flange side view.
In figure, 1 is blow-off pipe, and 2 is standard flange, and 3 is blow through valve, and 4 is offset hole flange, and 5 is bolt, and 6 is to blow down
Device adpting flange, 7 is pad, and 8 is liquid goods pipe.
Specific embodiment
The utility model is described further with reference to embodiment, it is necessary to explanation is, it is right that embodiment is not constituted
The limitation of the claimed scope of the utility model.
The utility model sets offset hole flange 4 and welds blow-off pipe 1, the other end of blow-off pipe 1 welding common stainless steel mark
Blow through valve 3 of the connection with snap joint of quasi- flange 2, sets pad 7 between standard flange 2 and blow through valve 3；The bottom of blow-off pipe 1
Need to be concordant with the inwall bottom of liquid goods pipe 8 blown down, the welding of liquid goods pipe 8 blowing-down device adpting flange 6 and offset hole flange 4 it
Between connected by teflon gasket 7 and bolt and nut 5.
Above-mentioned part all extends it and uses the longevity in addition to pad 7 is polytetrafluoroethylene (PTFE) using stainless steel SUS316L
The kinds of goods ordered and taken up suitable for chemical tanker.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any one skilled in the art in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its inventive concept is subject to equivalent or change, should all cover protection domain of the present utility model it
It is interior.
