Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

example 1

With reference to fig. 1 to 6, the aluminum alloy plastic-lined gas drive urea tank comprises an aluminum alloy tank body, wherein the aluminum alloy tank body comprises a tank body 1, two ends of the tank body are connected with end sockets 2, and a plastic-lined layer 3 is rotationally molded on the inner walls of the tank body and the end sockets.

The main material of the plastic lining layer 3 is crosslinked polyethylene material, and the thickness of the plastic lining layer is 3-4 mm. The lining plastic layer is uniformly coated on the inner walls of the barrel body and the end enclosure.

One end socket is provided with a urea sensor connecting flange 4, a filling opening 5 and a pressure sensor mounting opening 6, and the other end socket is provided with a water outlet 7.

The seal head, the urea sensor connecting flange, the filling port, the pressure sensor mounting port and the water discharge port are all made of aluminum alloy materials.

The urea tank is integrally made of aluminum alloy materials, and is low in manufacturing cost and light in weight.

The lining is moulded the urea jar that the layer can prevent aluminum alloy material and is corroded by urea, and compares and drives the urea jar with stainless steel material gas, the utility model discloses an inside cleanliness is more excellent.
