The two ends of the protection sleeve pipe 3 are tightly connected with two snap joints 4 respectively；Discharge opeing is provided with the protection sleeve pipe 3
Mouth 5.
The antispray chemical feed pipe that the utility model is provided, on the basis of the display leakage point chemical feed pipe, outside
Portion has covered one layer of protection sleeve pipe, and protection sleeve pipe is located at outermost layer, is used to protect chemical feed pipe and colour developing coating, and protection sleeve pipe is transparent
Material, when convey tracheal rupture after, liquid is blocked by protection sleeve pipe, liquid spray after along protection sleeve pipe inner side flowing, to specify
Leakage fluid dram discharge safely, certain inhibitory action is played in protection leakage of the sleeve pipe to liquid, while liquid flows through a colour developing painting
Layer discoloration, can intuitively find leakage point, using the connected mode of snap joint, be easy to repair or change pipeline in time.
Based on this, the utility model than original technology, with can quickly determine chemical feed pipe leakage part and place
The advantage of liquid splash.
In the alternative of the present embodiment, the protection sleeve pipe is soft materials.It is preferred that also there is certain elasticity.
Protection sleeve pipe is soft, elastic transparent material, and after tracheal rupture is conveyed, liquid is blocked by protection sleeve pipe, liquid
Along the inner side flowing of protection sleeve pipe after ejection, safe discharge is gone out to the opening specified, the leakage of the protection sleeve pipe of elasticity to liquid
Play certain inhibitory action.
In the alternative of the present embodiment, the material of the protection sleeve pipe is Teflon.
Polytetrafluoroethylene (PTFE) Polytetrafluoroethene, english abbreviation is PTFE, (being commonly called as " King "), in China,
Due to the reason pronounced, " Teflon " this trade mark is referred to as Teflon, Teflon, iron richness dragon, Teflon, teflon etc. again
Deng being all the transliteration of Teflon.
The product of this material is typically referred to as " non-sticking lining ", is that all hydrogen are former during one kind has used fluorine to replace polyethylene
The artificial synthesized macromolecular material of son.The characteristics of this material has antiacid alkali resistant, resists various organic solvents, is practically insoluble in institute
Some solvents.Meanwhile, polytetrafluoroethylene (PTFE) has resistant to elevated temperatures feature, and its coefficient of friction is extremely low, thus can make lubrication it
It is remaining, also become the preferable coating of non-stick cooker and water pipe internal layer.
The chemical feed pipe of the application is acid or alkali because of conveying, therefore must use the material of acid and alkali-resistance, in these materials
In material, Teflon acid-alkali-resistant degree is extremely strong, and price is also more cheap, suitably uses.It is of course also possible to select other material as needed
Material.
In the alternative of the present embodiment, switch is provided with the leakage fluid dram.
Leakage fluid dram is used to discharge the liquid for spilling, accordingly, it would be desirable to add switch so as to control the outflow of liquid.Switch can be with
Using valve etc. form.
In the alternative of the present embodiment, the snap joint is ferrule-type compression joint.
Ferrule-type compression joint-it is Applicable media：The non-aggressives such as Oil, Water, Gas or Korrosionsmedium, sealed fitting,
After being connected with pipeline, the features such as with firm, good seal performance is connected, thus in oil refining, chemical industry, light industry, weaving, national defence, smelting
It is widely adopted in the systems such as gold, aviation, ship；It is also applied for the hydraulic drive pipeline such as various mechanical engineerings, machine tool.This
Application belongs to perishable chemical field, is relatively adapted to ferrule-type compression joint.Connected mode can be inserted into card using chemical feed pipe
In sleeve type pipe joint, and the mode being bonded on the outer wall of pipe joint of bobbin seal is protected, or be directly made of one formula etc.
Deng.
Finally it should be noted that：Various embodiments above is only used to illustrate the technical solution of the utility model, rather than it is limited
System；Although being described in detail to the utility model with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
