After refueling at the gas station
Will any friends be curious
The pipe for refueling is so long
Is there still a part left in the tube?
Can a shake of the tube come out?
No, there are car owners who really did this
In Heze, Shandong
A woman happened to see it at a gas station
The owner of the car in front of the gas
Make a strange move
The owner of the car was a young lad
The cheerer is cheering for it
The man was carrying a gas pipe in his hand
The lady didn't understand the man's intentions at first
Take a closer look later
It turned out that the man was worried about the inside of the gas pipe
There is residual gasoline, afraid of loss
I wanted to "shake" the gasoline in the tubing into the tank
Is it really useful to shake the tubing like this?
After adding oil
Is there any oil left in the tubing?
Can it flow out with a shake?
In fact, the oil dispenser oil pipe has installed a check valve to prevent the occurrence of "reflux", after adding oil, the fuel gun switch has been closed, no matter how to shake, will not produce a drop of oil Oh ~ ~
You car owners do not have to worry about their own loss, do not know whether you have noticed, as long as the gas gun is switched on and off, it will produce oil, this is because the tubing is always full of oil. It is precisely because of this check valve that the refueling gun can be "ready to be on standby", open the switch to refuel, and do not need to wait until the gasoline is full of tubing to enter the fuel tank.
Well, another netizen has to ask
Why is the fuel dispenser tubing black
Can you make the tubing transparent?
Dispenser hose, also known as "special tubing for refueling pump". It needs to meet the requirements of heat resistance, high voltage resistance, static conductivity, flame retardancy, etc., and is generally composed of an inner layer, an outer layer and an intermediate layer.
The inner layer of the tubing is an oil-resistant hose consisting of smooth, fuel-resistant rubber. The outer layer is abrasion-resistant rubber, which consists of non-corrugated, fuel-resistant rubber. The middle layer is a metal braided wrapping layer, which is composed of reinforcing materials, which makes the tubing more pressure-resistant and can also play a role in conducting electricity.
Because there is a metal braid wrapping layer, even if the tubing is transparent, you can only see the steel wire inside.
