Description

Technical Field

[0001] The present invention relates to the technical field of fuel support for guided munitions, and in particular to a universal pipeline system and an operating method for fuel support for guided munitions. Background Art

[0002] Currently, fuel supply for guided munitions is the most complex aspect of support, requiring specialized refueling equipment. This includes quantitative / non-quantitative fuel filling, fuel draining, quantitative oil drainage, fuel replenishment, fuel anti-icing agent mixing, fuel pumpback, pipeline backflow, automatic pipeline cleaning, and ammunition pipeline cleaning. This involves multiple operations, including pressure and speed adjustment, and leak-tightness checks. The associated refueling equipment features complex piping arrangements, requiring operators to adjust multiple manual and control valves while simultaneously switching multiple output interfaces. This cumbersome operation leads to low support efficiency and high skill requirements, hindering the development of universal, streamlined, and simplified ammunition support. Summary of the Invention

[0003] In view of this, the present invention provides a universal pipeline system and operation method for guided ammunition fuel support, which can achieve universalization, process standardization and simplification of ammunition support.

[0004] The technical solution adopted in the present invention is as follows:

[0005] A universal pipeline system for fuel supply of guided munitions, comprising a fuel supply source, two or more fuel supply lines, a fuel return line, a selection valve, a controller and a touch screen;

[0006] More than two oil supply circuits are connected in parallel, and the oil inlets of the oil supply circuits are connected to the oil supply source, and flow meters are provided on the oil supply circuits; one side port of the oil return circuit is connected to all the oil supply circuits at the same time, and the other side port of the oil return circuit is connected to the oil supply source, and a selection valve is provided on the oil return circuit for selecting the specified oil supply circuit simultaneously or individually; the touch screen is used to display the operation process or perform touch-screen operation, and the controller is used to realize quantitative fuel filling, non-fixed fuel filling, fuel discharge, quantitative oil discharge, pipeline back suction, fuel replenishment, fuel monitoring, fuel anti-icing agent mixing, pipeline cleaning, and guided ammunition fuel system cleaning.

[0007] Furthermore, a proportional control valve, an oil pump, an oil supply control valve, and an oil outlet control valve are sequentially arranged on the pipeline between the oil inlet and the oil outlet of the oil supply circuit, and a parallel loop control valve is connected between the proportional control valve and the oil outlet control valve.

[0008] Furthermore, an oil return port is provided on the oil return line, and an oil return control valve is provided on the pipeline between the oil return port and the oil supply source.

[0009] Furthermore, the oil supply source includes an oil storage tank, a liquid level gauge assembly, an oil supply control valve, a filter, a filter control valve and associated pipelines;

[0010] The liquid level and temperature information in the oil storage tank are monitored by the liquid level gauge component, transmitted to the controller and displayed on the touch screen. The oil supply control valve, filter, and filter control valve are sequentially arranged on the pipeline between the oil storage tank and the oil supply line.

[0011] A method for operating a universal pipeline system for fuel supply of guided munitions, using the above-mentioned pipeline system, is as follows:

[0012] During quantitative fuel filling, the operator sets the fuel filling amount for each fuel supply line in the controller and starts the filling operation. The fuel flows from the oil tank through the fuel supply control valve and enters the filter of each fuel supply line. When a fuel supply line is selected, the oil pump starts to extract fuel and supplies it to the outside through the filter control valve, proportional control valve, flow meter, fuel supply control valve, oil outlet control valve, and oil outlet. When the flow meter reaches the set value, the system automatically stops working. During operation, it can be manually controlled to stop. If reset, the system can continue to fill the remaining amount and automatically stop.

[0013] When the fuel is not quantitatively added, the operator supplies fuel to the outside through the fuel supply line. When a fuel supply line is selected, the oil pump starts to extract fuel, and then supplies fuel to the outside through the filter control valve, proportional control valve, flow meter, fuel supply control valve, oil discharge control valve, and oil outlet. The non-quantitative filling is manually controlled to start and stop, and the filling amount can be accumulated;

[0014] When draining fuel, select a fuel supply line on the touch screen, connect its corresponding oil outlet to the overflow / drain port of the guided ammunition, open the ammunition vent, and after starting, close the oil pump, loop control valve, and oil outlet control valve. The selector valve selects the selected fuel supply line to extract the fuel from the ammunition and discharge it through the oil return port until it is completely drained.

[0015] When discharging oil quantitatively, select an oil supply line on the touch screen and set the oil discharge volume. After starting, close the oil pump, loop control valve, and oil discharge control valve. The selector valve selects the selected oil supply line to extract the fuel from the ammunition and discharge it through the oil return port. The flow meter measures the flow and the system automatically stops when the set value is reached.

[0016] When the pipeline is sucked back, select the pipeline sucked back function on the touch screen, select an oil supply line, and after starting the function, close the oil pump, loop control valve, and oil outlet control valve. The selected oil supply line is selected by the selection valve, and the pipeline oil is sucked back to the oil storage tank through the return oil port and the return oil control valve, or discharged directly;

[0017] When refueling, the oil tank is connected to the aircraft refueling truck through the aviation pressure valve to refuel; or the oil outlet of the oil supply line is connected to the external oil source, and the oil is replenished into the oil tank through the oil return port and the oil return control valve through the back suction function;

[0018] When mixing fuel and anti-icing agent, add the anti-icing agent to the oil tank, select the fuel mixing function on the touch screen, and after starting, close the loop control valve, oil supply control valve, and oil outlet control valve on all oil supply lines, start the oil pump, open all other valves, and circulate oil extraction and return to the oil tank to form a two-way circulation. When the fuel in the oil tank is mixed three times, the system automatically stops;

[0019] When the pipeline is automatically cleaned, select the automatic pipeline cleaning function on the touch screen. After starting, close the loop control valves, oil supply control valves, and oil outlet control valves on all oil supply lines, start the oil pump, open all other valves, and circulate the oil in the oil tank to extract and return oil, forming a two-way loop, and cycle three times; then open the loop control valves on all oil supply lines to clean the return oil pipeline, and cycle three times; open the oil supply control valves, oil outlet control valves, and oil outlets on all oil supply lines to drain all the remaining fuel in the oil tank and pipelines, and the automatic cleaning is completed;

[0020] When cleaning the guided ammunition fuel system, select the ammunition cleaning function on the touch screen, connect the oil outlet of the first oil supply circuit to the ammunition filling port, connect the oil outlet of the second oil supply circuit to the ammunition overflow port / drain port, and close other oil supply circuits; the first oil supply circuit performs the non-quantitative filling function, and the second oil supply circuit performs the fuel drain function. The drained fuel is controlled by the second oil supply circuit through the selection valve and discharged directly through the oil return port; the two oil supply circuits are a group, which are connected to other groups in sequence. Each oil supply pipeline in each group performs the non-quantitative filling function and the fuel drain function respectively.

[0021] Furthermore, during fuel monitoring, the liquid level and temperature information in the fuel tank is monitored by the liquid level gauge component, transmitted to the controller, and displayed on the touch screen.

[0022] Furthermore, when the fuel is quantitatively added, all the fuel supply lines can perform quantitative fuel addition at the same time; when the fuel is discharged, all the fuel supply lines can perform the discharge work at the same time, and the fuel in the ammunition does not enter the oil storage tank; when the pipeline is back-sucked, all the fuel supply lines can perform pipeline back-sucking at the same time.

[0023] Beneficial effects:

[0024] 1. The present invention integrates the fuel filling processes of various guided munitions through an automated system control system combining a controller and a touch screen, optimizes the pipeline design, and pre-sets the support operation processes and related functions for various types of munitions in the system. Through the human-machine interface, the relevant actuators such as oil pumps and valves can be controlled and selected and executed with one click, realizing "multi-type, multi-functional, and universal" fuel operation support.

[0025] 2. The present invention can use the fuel in the system oil storage tank or an external oil source, and is widely applicable and can be selected according to actual working conditions.

[0026] 3. The present invention has the functions of ensuring simultaneous quantitative fuel filling, fuel discharge and pipeline back-suction for multiple guided munitions of the same or different types. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0030] The present invention provides a universal pipeline system for fuel support of guided ammunition, comprising an oil supply source, two or more oil supply lines, an oil return line, a selection valve, a controller and a touch screen.

[0031] Two or more oil supply circuits are connected in parallel, the oil inlets of the oil supply circuits are connected to the oil supply source, and flow meters are installed on the oil supply circuits; the port on one side of the oil return circuit is connected to all the oil supply circuits at the same time, and the port on the other side of the oil return circuit is connected to the oil supply source, and a selection valve is provided on the oil return circuit for selecting the specified oil supply circuits simultaneously or individually; the touch screen is used to display the operation process or perform touch-screen operations, and the controller is used to realize quantitative fuel filling, non-fixed fuel filling, fuel discharge, quantitative oil discharge, pipeline back suction, fuel replenishment, fuel monitoring, fuel anti-icing agent mixing, pipeline cleaning, and guided ammunition fuel system cleaning.

[0032] like Figure 1 As shown, this embodiment uses two oil supply circuits, with the first oil supply circuit and the second oil supply circuit connected in parallel. A proportional control valve I10, an oil pump I4, an oil supply control valve I16, and an oil delivery control valve I18 are sequentially provided on the pipeline between the oil inlet I28 and the oil outlet I20 of the first oil supply circuit. A circuit control valve I12 is connected in parallel between the proportional control valve I10 and the oil delivery control valve I18. A proportional control valve II11, an oil pump II5, an oil supply control valve II17, and an oil delivery control valve II19 are sequentially provided on the pipeline between the oil inlet II29 and the oil outlet II21 of the second oil supply circuit. A circuit control valve II13 is connected in parallel between the proportional control valve II11 and the oil delivery control valve II19.

[0033] An oil return port 27 is further provided on the oil return line, and an oil return control valve 23 is provided on the pipeline between the oil return port 27 and the oil supply source.

[0034] The oil supply source can use the fuel from the system oil storage tank or an external oil source. In this embodiment, the oil supply source uses the fuel from the system oil storage tank, including the oil storage tank 1, the liquid level gauge assembly 2, the oil supply control valve III3, the filter I6, the filter II7, the filter control valve I8, the filter control valve II9 and the auxiliary pipelines; the liquid level and temperature information in the oil storage tank 1 are monitored by the liquid level gauge assembly 2, transmitted to the controller and displayed on the touch screen 26, and the oil supply control valve, the filter, and the filter control valve are sequentially arranged on the pipeline between the oil storage tank 1 and the first oil supply oil circuit inlet I28 and the second oil supply oil circuit inlet II29.

[0035] Using the above piping system, the operation method is as follows:

[0036] A 24V DC explosion-proof oil pump, model: 20GZB-3 / 2.5K, is used. Its working pressure is 0-0.3mpa and flow rate is 55L / min. The flow rate can be adjusted by proportional control valve I10 and proportional control valve II11. The pressure is adaptively controlled by the guided ammunition to meet the designed oil supply requirements, providing fuel output with a filling pressure of 0-0.3mPa and a flow rate of 0-50L / min.

[0037] The two oil supply lines can work independently or simultaneously, supplying external oil from the oil outlet Ⅰ20 and the oil outlet Ⅱ21 respectively; the flow meters Ⅰ14 and Ⅱ15 installed in the two oil supply lines measure the oil delivery volume, and have the function of ensuring the simultaneous quantitative fuel filling of two guided ammunitions of the same or different types.

[0038] This system has the function of ensuring the fuel supply operation of various types of guided ammunition. The controller 25 is a programmable computer controller (PCC), which is programmed and integrated with the fuel supply operation process of multiple types of ammunition and displayed on the touch screen 26. The touch screen 26 can be used to switch, select, and execute to control other execution elements and realize different operation functions.

[0039] During metered fuel refueling, the operator sets the fuel refueling amount for each fuel supply line in the PCC controller 25 and initiates the refueling operation. Fuel flows from the fuel tank 1 through the fuel supply control valve III 3 and enters the filter of each fuel supply line. When a fuel supply line (the first or second fuel supply line) is selected, the fuel pump I starts, pumping fuel through the filter control valve I, proportional control valve I 10, flow meter I 14, fuel supply control valve I 16, fuel delivery control valve I 18, and fuel outlet I 20. When the flow meter I 14 reaches the set value, the system automatically stops. During operation, the system can be manually stopped. If reset, the system can continue to fill the remaining amount and then automatically stop. The metered refueling process for the second fuel supply line is the same as that for the first fuel supply line. Both the first and second fuel supply lines can also be metered refueled simultaneously.

[0040] When the fuel is not added in a quantitative manner, the operator supplies fuel to the outside through the fuel supply line. When a fuel supply line (the first fuel supply line or the second fuel supply line) is selected, taking the first fuel supply line as an example, after the oil pump Ⅰ4 is started, the fuel is extracted and supplied to the outside through the filter control valve Ⅰ, the proportional control valve Ⅰ10, the flow meter Ⅰ14, the fuel supply control valve Ⅰ16, the oil outlet control valve Ⅰ18, and the oil outlet Ⅰ20. The non-quantitative filling is started and stopped by manual control, and the filling amount can be accumulated; the non-quantitative fuel filling process of the second fuel supply line is the same as the process of the first fuel supply line.

[0041] To drain fuel, select a fuel supply line (either the first or second) on touch screen 26, connect outlet I 20 or II 21 to the guided ammunition overflow / drain port, and open the ammunition vent. Taking the first fuel supply line as an example, after activation, the fuel pump I 4, loop control valve I 12, and oil outlet control valve I 18 are closed. The first fuel supply line is then opened by selector valve 22, drawing fuel from the ammunition and discharging it through return port 27 until it is completely emptied. Alternatively, the second fuel supply line is activated, and the fuel drain process is identical to that of the first. Both the first and second fuel supply lines can also drain simultaneously, preventing the fuel in the ammunition from entering the fuel tank 1.

[0042] After completing the fuel refueling mission, guided munitions enter combat readiness duty. During this period, if the combat mission is adjusted, a certain amount of loaded fuel will be discharged, requiring quantitative discharge. To perform quantitative discharge, a fuel supply line (first or second) is selected on the touch screen 26, and the discharge volume is set. After activation, the fuel leakage prevention function can be used. Taking the first fuel supply line as an example, the fuel pump I4, loop control valve I12, and oil output control valve I18 are closed. The first fuel supply line is opened by the selector valve 22, and fuel in the ammunition is drawn out through the oil return port 27. The flow meter I14 measures the flow and automatically stops when the set value is reached. Alternatively, the second fuel supply line can be activated. The quantitative discharge process is the same as that of the first fuel supply line.

[0043] After a refueling mission, a large amount of fuel will remain in the pipeline. Long-term storage can contaminate the pipeline, or cause environmental pollution when the system is decommissioned, necessitating pipeline backflow. To perform pipeline backflow, select the pipeline backflow function on touch screen 26 and choose a fuel supply line (either the first or second). Once the function is activated, using the first fuel supply line as an example, oil pump I4, loop control valve I12, and oil output control valve I18 are closed. The first fuel supply line is then opened by selector valve 22, which then returns the pipeline oil to tank 1 or discharges it directly through return port 27 and return control valve 23. Alternatively, the second fuel supply line can be activated, and the pipeline backflow process is identical to that of the first fuel supply line. Both the first and second fuel supply lines can also perform pipeline backflow simultaneously.

[0044] When refueling, the oil storage tank 1 is connected to the aircraft refueling truck through the aviation pressure valve 24 to refuel; or it is connected to an external oil source through the oil outlet Ⅰ20 of the first oil supply circuit and the oil outlet Ⅱ21 of the second oil supply circuit, and the oil is refilled into the oil storage tank 1 through the return oil port 27 and the return oil control valve 23 through the back suction function.

[0045] During fuel monitoring, the liquid level and temperature information in the fuel tank 1 is monitored by the liquid level gauge assembly 2, transmitted to the PCC controller 25, and displayed on the touch screen 26.

[0046] Fuel anti-icing agent mixing. When guided ammunition is performing high-altitude missions, in order to prevent free water in the fuel from freezing at low temperatures and causing blockage in the oil pipeline, anti-icing agent must be added to the middle of the fuel and thoroughly stirred to mix it evenly. Add the anti-icing agent to the oil storage tank 1, select the fuel mixing function on the touch screen 26, and after starting, close the loop control valves, oil supply control valves, and oil outlet control valves on all oil supply lines (i.e., loop control valve I12, oil supply control valve I16, and oil outlet control valve I18 on the first oil supply line, and loop control valve II13, oil supply control valve II17, and oil outlet control valve II19 on the second oil supply line), start oil pumps I4 and II5, open all other valves, and circulate and extract and return oil from the oil storage tank 1 to form a two-way circulation. When the fuel in the oil storage tank 1 is mixed three times, the system automatically stops.

[0047] When the pipeline is automatically cleaned, select the automatic pipeline cleaning function on the touch screen 26, refer to the fuel mixing function, and after starting, close the loop control valves, oil supply control valves, and oil outlet control valves on all oil supply lines, start the oil pump, open all other valves, and circulate the oil in the oil storage tank 1 to extract and return oil, forming a double-circuit circulation, and cycle 3 times; then open the loop control valve I12 and the loop control valve II13 to clean the return oil pipeline, cycle 3 times, open the oil supply control valve I16, the oil supply control valve II17, the oil outlet control valve I18, the oil outlet control valve II19, the oil outlet I20, and the oil outlet II21 to drain all the remaining fuel in the oil storage tank 1 and the pipeline, and the automatic cleaning is completed.

[0048] To clean the guided ammunition fuel system, select the ammunition clean function on touch screen 26. Connect outlet I 20 of the first fuel supply circuit to the ammunition filling port, and outlet II 21 of the second fuel supply circuit to the ammunition overflow / drain port. The first fuel supply circuit performs the non-quantitative filling function, while the second fuel supply circuit performs the fuel drain function. The drained fuel is controlled by selector valve 22 and discharged directly through return port 27. The function settings of the first and second fuel supply circuits can be interchanged in the process. If there are more than two fuel supply circuits, connect each group of two fuel supply circuits in sequence. Each fuel supply circuit in each group performs the non-quantitative filling function and the fuel drain function respectively, while the other groups of fuel supply circuits are closed.

[0049] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
