Abstract

The invention relates to fire fighting equipment and, in particular, to tanks intended for the transport of water and other fire extinguishing liquids, and can be used in other areas of the national economy. The goal is to increase stability with incomplete refueling. The tank contains a hull, a filler neck, filling nozzles 4 from the pump (water supply system), suction tube, connecting pipe, tank with pump, control tube 11. To reduce roll and danger of overturning of the vehicle with an incompletely filled tank during changes and turns at high speeds, the tank is equipped with two longitudinally arranged inclined partitions 6, which divide it into three compartments, with notches 10 in the upper part of the partitions, which communicate the middle compartment 8 with the neck, and in the lower part of the partition 6, there are articulated valves 13, which regulate the flow of fluid from one compartment to another and prevent mixing of the center of mass of the fluid in the indicated modes of movement. To simplify the manufacturing technology, the longitudinally mounted partitions are mounted vertically, and the valves are connected to the cable controlling them. 3 il. (L 4i and OS: OS SP

Description

FIG. 2

The invention relates to knife-making machinery, and specifically to tanks intended for the transport of water and other fire-extinguishing liquids that are part of fire tank trucks and other fire engines, and can also be used in other machinery industries for similar products.

The purpose of the invention is to increase stability during partial refueling.

FIG. 1 schematically shows a tank with inclined longitudinally arranged partitions, longitudinal section; in fig. 2 is the same cross section; FIG. 3 - tank with vertical longitudinally arranged partitions, cross section.

The tank contains a housing 1, which includes a filler neck 2, a sump 3, filling nozzles 4 from a pump (water pipeline) and a suction pipe 5 immersed in a sump 3 and connected to a pump (not shown).

Inside the hull there are two continuous longitudinally arranged inclined partitions 6, which divide the volume of the tank into three compartments 7, 8 and 9. There are cutouts 10 in the upper ganging-off edges of the partitions 6, through which the middle compartment 8 communicates with the filler neck 2. Extreme compartments 7 and 9 communicate with the filler neck 2 directly. The control pipe 11, passing from the filler neck 2 through the partition 6 and the bottom wall of the housing 1, communicates the upper part of the filler neck 2 with the atmosphere. At the bottom of the partitions 6, holes 12 are made, communicating respectively the extreme compartments 7 and 9 with the middle section 8. Open the holes 12 with 1 valves 13 pivotally suspended on the axes 14. To simplify the manufacturing technology, the longitudinally arranged partitions can be installed vertically (FIG. 3). In this case, the extreme compartments communicate with the filler neck by means of caps 15 through the openings 16 and 17 in the housing 1 and the filler neck 2, respectively. To open the valves when filling the tank through the filler neck 2, provide a control cable 18 (shown through the filler neck). The hatches in the hull lining that serve to inspect and inspect the compartments are not shown in the drawings.

Depending on the speed of the vehicle and the extent of the curves to be overcome, it may be possible to manufacture tanks with either hermetic compartments and valves that prevent liquid flow, and those that are not fully sealed, which limit the amount of flow.

The proposed device works as follows.

and 2 a filler cap (not shown) opens. The liquid is poured into the side compartments 7 and 9. Under the influence of the mass of liquid, the valves 13 automatically open and the compartment 8 is filled according to the principle of communicating vessel. The air is removed through the notch 10 and the filler neck 2.

When arranging the tank of FIG. 3, prior to filling, it is necessary to open valve 13 with the help of cable 18, after which the filling of all three compartments occurs unhindered.

In both cases, the uniformity of filling is ensured by proper selection of the cross sections of the holes 17.

When filling from the pump (water supply), the filler cap must be closed. With the device according to FIG. 3 to the tapans 13 should be opened with the help of a cable 18. Filling is carried out through three nozzles 4, each of which is introduced into one of the sections 7, 8, 9. Air is removed through the control pipe 11.

To empty the tank when the pump is running, a vacuum (vacuum) is created in the pipe 5, under the influence of which the liquid enters the pump and the valves 13 automatically open, together with three compartments 7, 8, 9. The atmospheric pressure is maintained inside the tank. 3 atmospheres entering the control pipe 11.

The movement of the vehicle along the curve. When rebuilding and turning a vehicle moving with an incompletely filled tank, centrifugal forces arise that tend to push the fluid back to the outer (but relative to the center of curvature) wall of the tank. The valve 13, adjacent to the outer wall of the tank, under the influence of the centrifugal force of the fluid in the middle compartment 8. fits tightly against the movement of fluid into the outer compartment. Fluid that is located in a compartment that is minimally distant from the center of curvature of the rotation can flow into the middle compartment 8.

In case the compartments 7, 8, 9 and the valves are sealed, the liquid in the unfilled tank can be moved to the middle compartment with the help of a pump before the start of movement, which completely eliminates the danger of overturning.
