Perforation is distributed on tube body, which is characterized in that be additionally provided with the outer tube covered on the separator tube in the fuel tank, the outer tube with
There is gap, the bottom end of the outer tube is lower than the position of the perforation and blocks with the separator tube and connects between the separator tube
It connects, the top of the outer tube is the top for being open and being higher by the separator tube.
Separator tube bottom end oral area connects oil inlet pipe, and top oral area is equipped with cover board.
Multiple holes are distributed on the cover board.
The perforation of the buffering tube outer surface is evenly distributed on the top of the separator tube tube body.
The bottom end of the outer tube is stretched out from tank bottoms, and the bottom end of the outer tube is higher than the bottom end of the separator tube, described
Outer tube bottom end oral area is welded with Outer Bottom Plating, and the Outer Bottom Plating welds together around the separator tube and with separator tube.
Outer tube bottom end oral area is welded with first flange, the first flange covers on the separator tube, the buffering
The lower position that the outer surface of pipe is located at the first flange is welded with the second flange around the separator tube, first method
Blue and second flange is fastenedly connected by bolt and nut component, and gasket is equipped between the first flange and second flange.
The bottom end oral area outer surface of the separator tube is welded with flange and is connect by the flange with oil inlet pipe.
The outer tube is seamless steel pipe.
The ratio between sectional area of the outer tube and the separator tube is 2:1.
Using the above structure, the outer tube higher than separator tube is added outside separator tube, and the height of outer tube is higher than separator tube
Highly, the outlet of outer tube is close apart from fuel tank liquid level, and in addition the section of outer tube is greater than the section of separator tube, then in outer tube
Gap is formed between surface and the outer surface of separator tube, when control defective valve near fuel tank, buffers the outer tube of tube outer surface
Greatly reduce the amount that oil liquid is flowed out from separator tube.Above structure improves the working efficiency and work quality of whole system.

Specific embodiment
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows, the fuel tank draining buffer unit of the utility model, including be passed through from tank bottoms described
The separator tube 100 of fuel tank is distributed with perforation 110 on the tube body of separator tube 100, is additionally provided with and is covered on separator tube 100 in fuel tank
Outer tube 200, has a gap between outer tube 200 and separator tube 100, the bottom end of outer tube 200 lower than perforation 110 position and with buffering
Pipe 200 blocks connection, and the top of outer tube 200 is the top for being open and being higher by separator tube 100.
The sectional area of outer tube 200 is greater than the sectional area of separator tube 100, is thus formed between outer tube 200 and separator tube 100
Gap.In addition the bottom end oral area of separator tube 100 connects oil inlet pipe by flange 300, and top oral area is equipped with cover board 120, and cover board
On multiple holes are distributed with.
Preferably, the ratio between sectional area of outer tube 200 and separator tube 100 is 2:1.
Specifically, the bottom end of the outer tube 200 in the present embodiment is stretched out from tank bottoms, and the bottom end of outer tube 200 is higher than buffering
The bottom end of pipe 100,200 bottom end oral area of outer tube are welded with Outer Bottom Plating 330, which welds around separator tube 100 and with separator tube
It is connected together, the closure of the bottom end and separator tube that finally realize outer tube 200 connects.Outer tube is seamless steel pipe.
When the work of the entire hydraulic system of the utility model, if the valve near fuel tank generates malfunction and failure, due to slow
Height has been added outside washing pipe close to the outer tube of oil level, has been prevented a large amount of oil and has been flowed out from separator tube, therefore has avoided oil liquid
It is lost, not only reduces loss while also protecting environment.
Embodiment 2
As shown in Fig. 4, Fig. 5, Fig. 6, the present embodiment and the difference of embodiment 1 are only that:
In the present embodiment, the bottom end of outer tube 200 is also stretched out from tank bottoms, and the bottom end of outer tube 200 is also above buffering
The bottom end of pipe 100.200 bottom end oral area of outer tube is welded with first flange 310,310 sets of the first flange on separator tube 100, delays
The lower position that the outer surface of washing pipe 100 is located at first flange 310 is welded with the second flange 320 around separator tube, the first method
Orchid 310 and second flange 320 are fastenedly connected by bolt and nut component 400, and between first flange 310 and second flange 320
Equipped with gasket.Other structures and embodiment 1 are all the same.The present embodiment can make the company between outer tube 200 and separator tube 100
Connect more secured, sealing effect is more preferable, can preferably avoid the loss of oil liquid, finally also achieve the bottom end of outer tube 200 with
The closure of separator tube connects.
Description through the above scheme, it can be seen that the utility model has the advantage that
This fuel tank draining buffer unit is easy to operate, with it is existing only by the device that separator tube is buffered compared with,
Height is added outside separator tube close to the outer tube of liquid level, so that greatly reducing from the oil mass that separator tube flows out, therefore avoids oil liquid
Loss, reduce economic loss while also protect environment.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
Variation, the modification of the upper embodiment will all be fallen in the claims of the utility model.
