Preferably, the cross section of the tank body is circular, oval or rectangular.

preferably, the end socket is spherical, concave-convex or planar.

Preferably, the connection included angle between the end socket and the inner wall of the tank body is more than 90 degrees, so that arc transition is formed. The utility model discloses form the circular arc transition, weaken and receive the shear force effect, effectively changed and decomposed the positive impact force of liquid to the head, the whole atress of head is more reasonable, durable.

Preferably, the top of the tank body is provided with a breather valve, and the manhole is connected with an emptying valve. When the pressure in the tank is higher than the set external pressure, the positive pressure valve rises to release the pressure to the outside, so that the pressure in the tank is quickly restored to be balanced; when the pressure in the tank is smaller than the set external pressure, the negative pressure valve descends, and external air enters the tank to restore the pressure in the tank to be balanced. The positive pressure valve is set to have a pressure of 0-1.0MPa, preferably 0-0.4MPa, according to the temperature difference change amplitude in the tank and the liquid vapor pressure; the negative pressure valve is set to a pressure of-0.09 to 0MPa, preferably-0.05 to 0 MPa.

preferably, the discharge port is connected with an emergency shut-off valve. The anti-corrosion type emergency cut-off valve adopts a split connection type of an upper valve body and a lower valve body, the upper valve body is internally arranged, the lower valve body is lined with Polyethylene (PE) by aluminum alloy, and the discharging is designed by 90 degrees or 135 degrees (45 degrees);

Common polypropylene (PP), Polyethylene (PE), polyvinyl chloride (PVC), etc. for plastic molding

Preferably, the reinforcing ribs are connected between the plurality of swash plates. This can provide strength of the connection between the swash plates.

Therefore, the utility model discloses a jar body is whole with the head and is made, and the dead weight is little, has improved conveying efficiency, reduces the cost of transportation of product, and the jar body does not have the welding seam, and intensity (especially rigidity) is high, and overall structure stress reinforcement effectively improves the transportation security performance of tank car. Meanwhile, safety accessories such as a breather valve and an emergency cut-off valve are arranged according to the road transportation standard of the vehicle, so that the overall safety prevention and control coefficient is high.
