In the communication vehicle in the prior art, the oil in the oil tank is viscous, especially in cold winter or under certain specific geographical positions and environments, the oil in the oil tank is excessively viscous due to low temperature, so that the communication vehicle cannot be effectively used, and an improved scheme for heating the oil tank exists.

However, in actual production practice, the following problems exist:

1. in the heating process of the oil tank of the communication vehicle in the prior art, a fuel oil heater conveys warm water or warm air to heat the oil tank, however, the on-off control is needed during the fluid conveying, and a corresponding valve is needed to control at the moment; meanwhile, the oil output in the oil tank also needs to be controlled by valves, and the excessive valves can cause the excessive number of equipment, so that the layout has difficult and unexpected space occupation.

2. In the prior art, a multi-way reversing valve exists, as shown in prior art fig. 1, the multi-way reversing valve can realize multi-way control by sliding a valve core and switching a plurality of positions, so that the number of valves can be effectively reduced, but one premise of the multi-way reversing valve is that the fluid is homologous, for example, the reversing valve only controls oil multi-way operation, and for different media such as oil/water, for example, oil/gas, the valve core inevitably generates mixing of different media in the sliding process, so that an execution end cannot normally work.

3. The prior art fuel oil heater only heats the fuel tank, however, other positions where liquid is easy to accumulate, such as in a valve, also have heating requirements, but the prior art has no corresponding solution.

4. In the prior art, the on-off of a circular channel and a small-size channel is difficult to control, and if the on-off of the circular channel and the small-size channel is controlled, a large amount of cost is increased.

5. The reversing valve and the multi-connected valve in the prior art can only realize one-way switching (such as an orthogonal multi-connected valve and a reversing valve) or simultaneous switching (such as a parallel multi-connected valve), and do not realize the function of a plurality of working states.

6. In the prior art, when the valve core is closed by spring force, the situation of insufficient spring force exists, and the problem cannot be well solved.

7. In the prior art, a fuel heater carries out local control through a drive-by-wire switch panel, cannot be connected into a centralized management and control system of a vehicle for unified monitoring, cannot be intelligently connected with a vehicle-mounted environment control system, and automatically carries out switching, temperature adjustment, flow rate adjustment and the like according to a vehicle-mounted environment.
