Description

EMU special efficient drain pipe

Technical field

The utility model relates to high speed motor car tubing manufacturing technology field, especially EMU special efficient drain pipe.

Background technique

China's high ferro and motor-car toilet adopt vacuum excrement collector, dirt has the dirt box of vehicle bottom to collect, be connected by a Stainless Steel Tube between closet with dirt box, because less, the irregular curved and inner tube wall fouling of caliber causes bore more and more thinner, vehicle operating some months is blocking just, because connecting tube is curved more, dredge very difficult, at substantial human and material resources.

Model utility content

The utility model is for the deficiencies in the prior art, and propose EMU special efficient drain pipe, the use on EMU can solve a difficult problem for blow-off line internal incrustation, blocking, alleviates maintenance and the maintenance cost of drain pipe.

In order to realize above-mentioned model utility object, the utility model provides following technological scheme:

EMU special efficient drain pipe, comprises drain pipe body and anti-stagnant layer,

Described anti-stagnant layer covers in described drain pipe inner body wall.

Further, described anti-stagnant layer sintering is in described drain pipe inner body wall.

The utility model EMU special efficient drain pipe, the use on EMU can solve a difficult problem for blow-off line internal incrustation, blocking, alleviates maintenance and the maintenance cost of drain pipe.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of EMU special efficient drain pipe described in the utility model.

Embodiment

Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.

EMU special efficient drain pipe as shown in Figure 1, comprises drain pipe body 1 and anti-stagnant layer 2,

Described anti-stagnant layer 2 covers on described drain pipe body 1 inwall.

Described anti-stagnant layer 2 sinters on described drain pipe body 1 inwall.

Anti-stagnant layer material is integrate Teflon(PTFE, FEP, PFA, ETFE) the blending material XDA-1 of characteristic.

The utility model EMU special efficient drain pipe, the use on EMU can solve a difficult problem for blow-off line internal incrustation, blocking, alleviates maintenance and the maintenance cost of drain pipe.
