Description

technical field [0001] The invention relates to the field of equipment related to communication vehicles, and the international classification number is H01, in particular to fluid control equipment for communication vehicles. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of technological level, the proportion of vehicles in people's life is getting higher and higher, and communication vehicles are widely used in military and civilian fields. Communication vehicles integrate various technologies such as electromechanical hydraulics. The application of centralized management and control systems for communication vehicles is an industry development trend. It integrates public platform equipment or task equipment into a human-machine interface for monitoring, reducing the difficulty of business operations and improving vehicle usage. Improve the efficiency of the vehicle and improve the intelligence and automatio...

Problems solved by technology

[0005]1. During the heating process of the fuel tank of the communication vehicle in the prior art, the fuel heater sends warm water or warm air to heat the fuel tank. At this time, corresponding valves are required to control; at the same time, the oil output in the oil tank also needs to be controlled by valves. Too many valves will lead to too many devices, resulting in difficulties in layout and undesired space occupation

[0006] 2. In the fluid control of the prior art, there is a multi-way reversing valve, such as the prior art figure 1 As shown, the multi-way reversing valve realizes multi-channel control by sliding the spool to switch multiple positions, which can effectively reduce the number of valves, but it has a premise that the fluids are from the same source. For example, the reversing valve only controls The multi-channel operation of oil, and for different media such as oil / water, such as oil / air, the spool will inevitably mix different media during the sliding process, resulting in the failure of the actuator to work normally

[0007]3. The fuel heater in the prior art only heats the fuel tank, but other places that are prone to liquid accumulation, such as inside the valve, also need to be heated. But there is no corresponding solution in the prior art

[0008]4. In the circular channel and small-sized channel of the prior art, it is difficult to control the on-off of the channel. If the circular shape and smaller size are to be controlled On-off often increases a lot of cost

[0009] 5. The reversing valves and multiple valves in the prior art can only realize one pass and one close (such as orthogonal multiple valves, reversing valves) or simultaneously pass break (such as parallel multi-valve), did not realize the function of multiple working states

[0010]6. In the prior art, when the spool is closed by spring force, there is insufficient spring force, which cannot be solved well
