It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] Example 1:

A ball valve a is provided at the intersection of the cab small water tank outlet interface 02 and the engine small cycle water hot water outlet 07, a ball valve b is provided at the connection between the No. 0 fuel tank heater outlet 03 and the converter body 1, and a ball valve c is provided at the intersection of the back pressure radiator upper port 04 and the back pressure radiator lower port 06.

[0037] In a possible implementation, the left and right ends of the converter body 1 are respectively the engine small cycle return water cooling water inlet 01 and the cab small water tank water inlet 05.

[0038] In one possible embodiment, two channels are provided in the ball valve a, wherein channel a1 is used to connect the engine small cycle water outlet hot water port 07 and the converter body 1, and channel a2 is used to connect the cab small water tank outlet interface 02 and the engine small cycle return water cold water interface and the No. 0 fuel tank heater water inlet 011.

[0039] In a possible implementation, a T-shaped channel is provided in the ball valve b, wherein the channel b1 is used to connect to the water outlet 03 of the No. 0 tank heater, and the channel b2 is used to connect to the channel b1 and connect the ball valve a and the ball valve c.

[0040] In a possible embodiment, two channels are provided in the ball valve c, wherein channel c1 is used to connect the ball valve b, the lower port 06 of the back pressure radiator and the water inlet 061 of the boiler water pump, and channel c2 is used to connect the water inlet 05 of the small water tank in the cab, the upper water outlet interface of the back pressure radiator and the water outlet 041 of the boiler heater.

[0041] In one possible embodiment, a boiler heater outlet 041 is provided at the lower bend of the tee on the upper port 04 of the back pressure radiator, which is connected to the water outlet of the boiler 09, the water inlet of the boiler 09 is connected to the water outlet of the fast and slow water pump 08, and the water inlet of the fast and slow water pump 08 is connected to the water pump inlet 061.

[0042] In one possible embodiment, a tee is provided downward at the lower bend of the tee to connect the water inlet 011 of the No. 0 fuel tank heater, the water outlet 041 of the automobile boiler heater, and the water inlet and outlet of the boiler water pump 061. This tee is drilled downward through the plate to connect the external L-shaped pipe for docking with the tee in the cab.

[0043] In one possible embodiment, the hot water interface 07 of the engine water outlet is in a right-angled L-shaped downward direction in the cab. It is drilled through the plate and passes out of the cab. The outer part is also in a right-angled L-shaped upward direction and is connected by inner and outer threads.

[0044] In one possible implementation, the water inlet 011 of the No. 0 box heater, the water outlet 041 of the automobile boiler heater, the boiler water pump port 061 and the right-angle lower bend 07 at the three-way lower bend are drilled through the plate at the same time, pass through the outside of the cab, and connect with the inner and outer threads of the L-shaped right-angle pipe outside the cab to play a fixing role.

[0045] Example 2:

[0046] A vehicle multifunctional preheating and heating converter, such as Figure 2As shown, during summer vehicle operation, ball valve a has two channels. Channel a1 connects the engine's small-circuit hot water outlet 07 and the engine's small-circuit cold water return 01, while channel a2 connects the vehicle's small water tank and the T-valve. During this time, channel a2 is inactive in the cab's small water tank, and the water circulating in channel a1 flows directly back into the engine's large-circuit system, eliminating hot air from the cab during summer.

[0047] Working principle:

[0048] like Figure 2 As shown, in summer, the water flow direction is from the hot water interface of the engine small circulation outlet to the a1 channel of the conversion valve 1, connecting 07 to flow to 01 and then directly back to the engine small circulation return water cooling outlet for use.

[0049] The water flow direction is from the engine small circulation water outlet to the HTH valve outlet 07 to 01 to the engine small circulation return water system, and the fuel tank heater outlet connection 03 is in the T-type valve closed state.

[0050] Example 3:

[0051] A multifunctional preheating and heating conversion valve for a vehicle, such as Figure 3 As shown, during winter vehicle operation, ball valve a is provided with two channels, wherein channel a1 is used to connect the engine small circulation hot water outlet O7 and T-valve b, and channel a2 is used to connect the cab small water tank outlet O2 and the engine small circulation return water cooling outlet No. 0 fuel tank heater inlet (01-011). Ball valve b is provided with a T-channel, wherein channel b1 is used to connect the No. 0 fuel tank heater outlet (03), and channel b2 is used to connect channel b1 and H valve a and H valve C. Ball valve c is provided with two channels, wherein channel c1 is used to connect the T-valve b and the boiler water pump 061 at the bottom of the back pressure radiator, and channel c2 is used to connect the car boiler main body (04-041) at the top of the back pressure radiator and the cab small water tank inlet 05.

[0052] Working principle: Figure 3As shown, in winter, when it is not started in winter and needs to be started, it works as follows: the fast and slow water pumps 08 are used to add water to the boiler 09 to the upper port of the north pressure radiator and the water outlet of the boiler heater (04-041) → the water inlet interface 05 of the cab small water tank → the water outlet 02 of the cab small water tank → the engine cold water return interface 01 and the water inlet of the No. 0 tank heater → the engine small cycle main body engine → the engine small cycle water outlet hot water outlet 07 → the T-type valve b1 connects the water outlet 03 and b2 of the No. 0 tank heater → C1 → the lower port 06 of the back pressure radiator, the boiler water pump water inlet 061 → the boiler water pump main body 08, to realize a whole cycle. During low water pressure conditions, due to the high installation position of the back-pressure radiator, the flow from the back-pressure radiator's lower water inlet port 06 to the back-pressure radiator's upper water outlet port 04 is slow when heating is not started. In winter, when the fuel tank heater's inlet and outlet ports 03 are not started, the fuel tank heater's outlet port 011 may need to be closed in a T-shaped position before opening. This is to ensure the engine is preheated first. This ensures that both the engine and fuel tank oil circuits are open, and the water resistance in the oil circuit is lower than that in the engine, allowing for faster preheating. Once the engine is preheated and the oil is wax-free, open the T-shaped valve at the appropriate time to preheat the fuel tank for three minutes to dewax the tank, achieving a temperature within -60 degrees Celsius and allowing the diesel engine to start normally using 0% diesel. The water resistance in the fuel tank is lower than that in the engine, which in turn is lower than the resistance in the back-pressure radiator. During winter, after the engine is started and in use, the boiler and engine can be used simultaneously. Once the engine is operating normally, shutting down the boiler allows the fuel tank to function normally. When the engine speed reaches 1600 rpm or above, the back-pressure radiator's resistance is approximately equal. When the engine speed exceeds 1800 rpm, the resistance exceeds the back-pressure radiator's resistance, allowing the back-pressure radiator to provide normal heating, achieving the goal of heating and reducing pressure. The hot water port 07 at the engine water outlet is connected to the return water port 01 at the engine cold water outlet.

[0053] Example 4:

[0054] A multifunctional preheating and heating conversion valve for a vehicle, such as Figure 4 As shown, there are two channels in the ball valve a, wherein channel a2 is used to connect the car small water tank outlet (02) → cab small water tank → car small water tank water inlet interface (05) → C1 → water pump inlet → boiler water pump (08) → boiler body (09) → boiler heater outlet → C2 → b2 → a2 → car small tank water outlet to form a cycle, wherein boiler water pump 08 → car boiler body 09 → boiler heater outlet 041 → back pressure radiator upper port 04 → back pressure body radiator → back pressure body radiator lower port 06 → boiler water inlet 061 → boiler water pump to form an overall cycle.

[0055] A T-shaped channel is provided in the ball valve b, wherein the channel b1 is in a closed state and the channel b2 is used to connect the H valve C and the H valve α.

[0056] There are two channels in the ball valve c, among which channel c1 is used to connect the small water tank 05 of the car and the water inlet interface 06 below the back pressure radiator → water pump inlet 061 → boiler water pump body, and channel c2 is used to connect the boiler heater 041, the water outlet interface 04 above the back pressure radiator and the T-type valve b2 channel.

[0057] Working principle:

[0058] like Figure 4 As shown, when the car stops on the road, the water is fed from the boiler booster pump inlet 061 → the boiler heater pump main body interface 08 → the vehicle boiler main body 09 → the boiler heater outlet 041 → the back pressure radiator upper water inlet 04 and C2 → the back pressure radiator main body and the cab small water tank → the back pressure radiator lower port 06 and (C2 → b2 → a2 → 02) the vehicle small water tank outlet 02 → the back pressure radiator lower port 06 and the vehicle small water tank water inlet 05 → the water pump inlet 061, forming an overall circulation.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
