Description

The invention relates to the field of devices for mass refueling of ground vehicles on the move.

When marching with the equipment of military units and subunits over long distances, it is important to timely refuel them on the advance routes while maintaining the established formation of columns on the marches.

When considering the technical literature most closely related to this issue, the following series of technical solutions were identified.

There are known field refueling stations with 10, 14 and 20 refueling points, each of which contains a set of collapsible equipment (a manifold with dispensing hoses and taps, a filter, a meter), a pumping facility (a fuel pumping station or a motor pump unit), rubber-fabric (elastic) tanks or tankers, semi-trailer for transporting a set of collapsible equipment (https://cyberleninka.ru/article/n/analiz-effektivnosti-primeneniya-sredstv-gmppovoy-zapravki- goryuchim-vooruzheniya-voennoy-i-spetsialnoy-tehniki-na -marshe/viewe).

The main disadvantage of these field refueling points is the inability to maintain the nominal pressure in the dispensing hoses with different quantities of simultaneously refueled military equipment (hereinafter in the text, the nominal pressure is understood as the maximum pressure at which, in the process of filling the fuel tanks of military equipment to the maximum level, a reverse reaction does not occur fuel exits from the fuel tank filler neck).

The problem solved by the invention is to eliminate these disadvantages by designing a complex for mass refueling of equipment with fuel, making it possible to maintain the nominal pressure in the dispensing hoses with different quantities of simultaneously refueled equipment.

The technical result of the invention is to increase the efficiency of refueling equipment on the move.

The stated problem is solved, and the technical result is achieved as a result of the fact that, according to the invention, the complex for mass refueling of equipment with fuel contains an automobile tank with a pump, a pressure hose, a distribution manifold with two valves installed at an equal distance from the ends of the distribution manifold, two distribution hoses, connected to the ends of the distribution manifold, two check valves and two bypass valves, two meters, each of which is installed on a corresponding distribution hose, two dispensing manifolds connected to the corresponding distribution hoses and equipped with dispensing hoses with dispensing valves, two bypass hoses, at each one end of which is connected to the bypass valve, and the other end is placed in the filler neck of the automobile tank; wherein the check valve and bypass valve are installed on the distribution manifold in series from the point of its connection to the distribution manifold; each meter is installed on the corresponding distribution hose after the installation location of the bypass valve in the direction of fuel supply; wherein the bypass valve is made in the form of a cylinder and includes a compression spring located in its internal cavity, mounted on the upper edge of the bypass valve, a piston mounted on the lower part of the compression spring, an inlet pipe mounted on the lower end face of the bypass valve, an outlet pipe mounted on the side the edges of the bypass valve at an equal distance from its end faces and connected to the distribution hose; wherein the height and stiffness of the compression spring correspond to the condition under which, in the mode of turning on all dispensing valves, the middle part of the side face of the piston is located at the level of the lower part of the side face of the outlet pipe, and in the mode of turning off all dispensing valves, the lower end face of the piston is located at the level of the upper part of the side face exhaust pipe; wherein the connection of the pressure hose is made in the middle of the distribution manifold; Moreover, the number of dispensing hoses with dispensing taps corresponds to the accepted quantity of simultaneously refueling equipment; wherein the connection of each distribution hose to the corresponding distribution manifold is made in the middle of the distribution manifold.

The invention is illustrated in Fig. 1-3.

In fig. 2 shows the bypass valve in the closing phase of the outlet bypass pipe (position 1).

The mass refueling complex for equipment works as follows.

When installing dispensing manifolds 5, the number of dispensing hoses 6 with dispensing taps 7 is taken based on the condition of their compliance with the accepted quantity of simultaneously refueling equipment.

When installing a complex for mass refueling of equipment with fuel, an automobile tank 1 equipped with a pump 11 is placed in the designated place for mass refueling of equipment with fuel on the march. A pressure hose 2 is connected to the pump 11, the free end of which is connected in the middle of the distribution manifold 3. The distribution manifold 3 is equipped with two valves 13 installed at an equal distance from the ends of the distribution manifold 3. A distribution hose 4 is attached to each end of the distribution manifold 3, the free end of which connected in the middle of the distribution manifold 5. On each distribution hose 4, sequentially from the point of its connection to the distribution manifold 3, a check valve 14 and a bypass valve 8 are installed. On each distribution hose 4, after the installation location of the bypass valve 8 in the direction of fuel supply, a meter 12 is installed.

The bypass valve 8 is made in the form of a cylinder. An inlet pipe 15 is secured to the lower end face of the bypass valve 8. An outlet pipe 16 is secured to the side face of the bypass valve 8 at an equal distance from its end faces. In the internal cavity of the bypass valve 8, a compression spring 18 is placed with a piston 17 attached to its lower part, secured a compression spring 18 on the upper edge of the bypass valve 8. The height and stiffness of the compression spring 18 is taken from the condition under which, when all distribution valves 7 are turned on on the corresponding transfer manifold 5, the middle part of the side face of the piston 17 is located at the level of the lower part of the side face of the outlet pipe 16 , and in the shutdown mode of all dispensing valves 7, the lower end face of the piston 17 is located at the level of the upper part of the side face of the outlet pipe 16.

An overflow sleeve 9 is connected to the outlet pipe 16, the opposite end of which is placed in the filler neck 10 of the automobile tank 1.

Before supplying fuel to the automobile tank 1, open the valves 13, turn on the pump 11, supply fuel to the pressure hose 2, the distribution manifold 3, the distribution hoses 4 through check valves 14 and meters 12, to the dispensing manifolds 5 and then through the dispensing hoses 6 and dispensing taps 7 into vehicle fuel tanks (not shown).

When a certain number of distribution valves 7 on the corresponding distribution manifold 5 is turned off as a result of an increase in pressure in the distribution manifold 5, the distribution hose 4 and the inlet pipe 15 of the bypass valve 8, the piston 17 is raised upward, acting on the compression spring 18, the internal cavity of the outlet pipe 16 is opened and directed fuel from the bypass valve 8 through the bypass sleeve 9 into the filler neck 10 of the automobile tank 1, thereby ensuring that the pressure in the dispensing hoses 6 is brought to the nominal value.

Thus, as a result of the implementation of the proposed technical solution, the efficiency of refueling equipment on the march is increased by ensuring automatic maintenance of the nominal pressure in the dispensing hoses with different quantities of simultaneously refueled military equipment.
