Description

The invention relates to devices for filling tanks, for example transport tanks, with a liquid product, in particular a liquid fuel.

A device for filling reservoirs with a liquid product is known, consisting of a housing with inlet and drainage nozzles, mounted above the last valve and located in the housing of the control valve ij.

The known device is the closest solution to the described invention to the technical essence and the achieved result.

However, it has low reliability.

The aim of the invention is to increase the reliability of the device,

This is achieved by the fact that the proposed device for filling tanks with a liquid product is provided with a tube installed coaxially or parallel to the drainage nozzle, the upper end of which is mounted in the membrane and the lower end has an additional valve and float.

In this case, a hole is formed in the tube to create a vacuum under the membrane after the valve is closed.

In addition, the device is equipped with a camera installed in the upper part of the body, which communicates with the diaphragm of the body through the valve and jet, and has a head through which the membrane with the stem and the tube with the valve are fixed, while its perimeter profile is communicated with the camera located at the top of the case.

To adjust the height of the device relative to the position of the tank, the pipe on the outer surface is threaded and has a nut with a toroidal gasket.

The overflow head is equipped with an additional tube located parallel to the tube with a valve, while the lower end of the additional tube is bent and placed under the valve of the tube.

In addition, the device is equipped with a device for controlling its operation, consisting of a vertical tube connected to the overflow head and a cable located in it, one end of which is connected to a valve mounted on the tube and the other to a stopper screwed onto the upper end of the vertical tube.

FIG. 1 shows schematically a device for filling tanks with a liquid product, a longitudinal section; and FIG. 2 - the same, the beginning of the overflow; in fig. 3 - the same, the moment when the level x of the liquid in the tank reaches the first critical level; in fig. 4 - the same, the moment when the decompression opening starts to act to neutralize the first secondary valve; in fig. 5 - the same, the moment when the main valve is lifted again to drain the liquid from the pipelines in front of it; in fig. 6 -. the same, the moment when the second minor valve finally stops transfusing; in fig. 7 shows a second embodiment of the device for filling tanks with a liquid product; in fig. 8 - the third embodiment of the device; in fig. 9 is a fourth embodiment of the device.

The device is mounted on a sleeve 1 fixed on the upper part of the tank 2 and includes a housing 3 with a cover 4 and a movable system placed inside the case and connected to the control unit 5 placed in the tank 2. The case has a supply and drain nozzle: and 6 and 7, a support surface 8 on which the membrane 9 and the days 10 are fixed. At the junction of the nozzle 7 and the bottom 10, the housing has a seat 11 on which the valve 12 is located,

The mobile system includes an overflow head 13 located inside the housing with a base having an external circular contour,

Valve profile. 12 supplements the profile of the saddle 11, with the valve 12 having guides 14 for engaging with the inner wall of the nozzle

Overflow head 13 channels 15 and 16 are used.

Tubes 17 and 18 are installed parallel or coaxially to the drain pipe 7, the upper end of which is mounted in the membrane 9, and the bottom has valves 19 and 20, while the valve 19 is located under the valve 20 and has a protective sheath 21 inside which is placed a float 22, made, for example made of porous material. Tubes 17 and 18 can be bent for a bayonet connection, but another connection is possible. Above the casing 21 is open (a protective cap 23 of the protective valves 23 and floats FROM contact with the liquid that passes through the pipe 7. Between the cap 23 and the casing 21 are formed channels to balance the pressure inside and outside the casing 21 regardless of the level of liquid in the tank 2. Membrane 9 serves to control the valve 12.

A hole 24 is formed in the tube 17 to create a vacuum under the membrane 9 after the valve is closed.

Inside the head 13 there is an eccentric chamber 25, coaxially with a channel 16 above which chamber 26 is located, is symmetrical with an overflow head 13, while the chambers are separated from one another by a plate 27. The overflow head 13 has a cover 28 having the shape of a truncated cone. In addition, there is an element 29 for pressing the membrane 30 to the corresponding protrusion of the head 13. The membrane 30 separates the chamber 26 from the chamber 31 and is equipped with a stem 32 for controlling a valve 33 located at the outlet of the channel 16 into the chamber 25. For controlling the stem 32 in the plate 27 and an element 29 are formed located underneath the other openings, and for communicating the channel 15 with the chamber 26. In the plates 27 there is another opening (not shown).

The membrane 9 divides the space of the housing 3 into two (the lower and upper chambers 34 and 35, the chamber 34 communicating with the inlet pipe 6, and the chamber 35 is limited by the space between the krlik 4 and the membrane 9. In the side wall of the chambers 25 and 26 there is a channel 36 communicated with cameras 26, 34 and 35.

In the upper part of the body 3, a chamber 37 is installed, with: 1 installed with the kopnyca over the embossed space through the valve 3S and the nozzle 39, at. this through the hole 40 of the camera 37 of the missing rod 41.

The device (Fig. 1-6) works as follows.

The device is installed in the upper part of the tank, which must be filled with liquid and connected to it by the pipe 6, while the tank (tank) and the device are mounted to a piping system (not shown).

As long as the closure of the tank from which the liquid is to be poured remains closed, all the organs of the device are positioned as shown in FIG. 1: valve 12 is located in the saddle 11. If the liquid level in tank 2 is low, then both valves 19 and 20 are open, float 22 is located on the lever (not shown -), raising the valve 19 against its seat, in the same way valve 20 raised above its nest, and valves 33 and 38 are closed.

If the drain valve of the tank from which the liquid is to be poured is opened, the latter enters the Chamber 34 and raises the drain head 13 due to the pressure of the ejection of the liquid and the pressure exerted by the liquid on the membrane 9. When the valve 12 rises above its nest, the liquid flows through the cutting log 7 into the reservoir 2. At that, the liquid jet penetrates into the channel 36 and then into the chamber 26 and flows out through the tube 17, the outlet simultaneously through the valve 19 and the orifice 24 (Fig. 2), while the valve 38 is raised, which provides communication between the cameras and 35 and 37. When the liquid level in tank 2 is high enough, the float 22 rises with liquid and the valve closes and the liquid flows through hole 24, the level of fluid in channel 36 rises and the liquid flows into chamber 35 and acts on the valve 9. The drain head balanced in this way deepens, the valve 12 is installed in its seat, the overflow stops. Part of the liquid out. chambers 35 can penetrate into KciMepy 37, since the valve 38 is initially raised, then the valve 38 is closed and the drain valve of the tank from which the liquid is poured is closed (Fig. 3). The liquid overflows through the opening 24 due to the volume of liquid in front of the valve 12. When the liquid overflows through the opening 24, some vacuum is created in the chamber 26, the membrane 30 deflects downwards, the rod 32 opens KJ.anaH 33, which contributes to a more rapid emptying chambers 26 and 35 through the tube 18 and the valve 20 (Fig. 4), and at this moment the pipes supply liquid to the drain valve of the supply tank disconnects c. As a result of the emptying of the chamber 35, the drainage head rises to the initial position of the start of the transfusion cycle. Thereafter, the fluid can again pass between the valve 12 and its seat, and the lower valve 19 remains closed (Fig. 5). If, as a result of a quick transfer, the float 22 closes the valve 20 Then the liquid rises the P chamber 35 while the valve 12 closes. Since the valves 19 and 20 are closed, the overflow is possible only through the opening 24, which can lead to an overflow of the tank 2, but after a long period of time. The overflow head (see Fig. 7) is located outside the housing 3 to eliminate pressure loss and decrease, the filling speeds, in this Device there are pipelines 42 and 43 for connecting the overflow head to the housing. 086 The housing is connected to the overflow head also by pipelines 44 and 45 (see Fig. 8). The device can be adjustable in height relative to the position of the tank 2, for which the drain connection on the outer surface has a thread 46 and a nut 47 with a toroidal gasket 48. The device works as follows (see figure 8). When the liquid level in tank 2 is below level 49, the float 50 is in the lower position so that valves 51 and 52 are open, valves 53 and 54 are closed and valve 55 is located on its seat, tightly closing the inlet channel of the tank. When the tanker pipeline is connected to the nozzle 56 and the tank valve is opened, the liquid enters chamber 57 and presses on the membrane 58, the valve 55 is raised and the liquid flows into the tank through the pipe 59 immersed in it, and a certain amount of liquid passes through pipe-60 as well through the opening 61 between the chamber 57 and the channel 62. Once the liquid in the tank reaches level 49 by raising the float 50, the valve 51 closes and the liquid does not go through the tube 60, but passes through the channel 62 and collects in the chamber 63, where a pressure higher than the latter in chamber 57 is poured. This pressure, by acting on the membrane 56, closes the valve 55, and the overflow is relieved. Since the valve 54 opens under the action of pressure, the latter is the same in chambers 57, 63-66 and blocks the entire system while it is maintained, i.e. open the tanker crane and connect the flexible hose. When the tank truck is closed to drain the fluid from the flexible hose, the pressure in chambers 57, 63 and 66 drops from Pj to P and the valve 54 closes, pressure is maintained in chambers 64 and 65, and pressure in chambers 57, 63 and 66 is relieved through drain hole 67 in the tube 60. Under pressure P on the membrane 68, the rod 69 is lowered and opens the valve 53. If the flexible hose between the tank truck and the tank is disconnected, the fluid will flow through the tube 70 and through the hole 67 of the tube 60, resulting in pressure in the chamber 63 drops from i, up to Р, and due to pressure on me The mlan 58 raises the clan 55. Since the nozzle 71 contributes to the creation of decompression in chambers 64 and 65, the valve 53 closes and stops access to the tube 70. If the tubes 60 and 70 are closed, the liquid can rise through the tube 60 and cause closing valve 55 but because

the presence of the drain hole 67 and the rate of discharge of fluid from the flexible hose; the fluid cannot accumulate on the membrane 58 in the chamber 63 and the valve 55 remains open during the drain.

After the completion of the fluid transfer, the valve 55 closes under its own weight, as does the valve 54, and the liquid from the tube 60 flows out through the drain hole 67 to its level. As the pumps pump the fluid, the float 50 lowers and opens the valve 51. The difference between the levels 49 and 72 of the fluid is selected on the basis of draining with flexible hoses of long length, and the liquid is poured before one reaches the level 72, If. re-transfuse: when the fluid level is between levels 49 and 72, then, at least 5 µm, the transfusion chain of the all-dygc system will operate as follows.

The fluid, supplied by PJ to cell 57, acts on the diaphragm 58, opens valve 55 and fills tube 60, closures; Valve-Yum 51, Then the liquid is filled by channel 62 and is collected in Kaj-63, The pressure increase from this chamber acts on the membrane 56- to close the valve 55, while there is no danger of overflowing over the edge and exceeding the level 72, since mg; About: Zenno

When the vessel overflows, the bone will reach Uroz 72, raising the float 50 causes closing valves 52 5 of tube 70, Since valves 55, 51 and 52 are closed and decompression cannot occur in chamber 63, the whole system is completely blocked, Valves 51 and 52 will open only when the spit falls down after the level v decreases. the tank pri.osose fluid pumps. When a bone / g level is reached 49, the device relieves; in the original position.

The device (see Fig. 9i) is equipped with a device for controlling its operation, consisting of a cable 73 connected to the overflow glue and 73/74 located in the KG & cable 74, one end of which is connected to valve 75 installed on the pipe 75, and the other with a stopper 77, screwing pus on the upper end of the tube 73

When a limited amount of fluid is supplied to control the operation of the device, it is enough to unscrew the plug 77 and pull out the cable 74 by 2-3 cm, while the float rises to level 49, the valve 76 cuts off and the leveling of the liquid stops from the tanker. Since zhi.dkost can not more-pass through the tube 75, then

it rises through channel 78 and collects in chamber 79, where Bisma pressure is established than in chamber 80, and, due to the pressure exerted on membrane 81, causes valve 82 to close.

Then, by connecting the tank with the tank truck, closing the drain valve last and disconnecting the hose with a break of 30, you can check the drain of the flexible connecting tube. In this case, the fluid passes through the tube 83 and through the drain hole 84 of the tube 75, and the resulting pressure arises as a result of this reduced pressure in Kai-79 79 allows the valve 82 to be lifted under pressure greater than the pressure in chamber 80 and acting on the diaphragm 81.

To control operation at level 72, the plug 77 is tightened without pHstcoB until the end so that the counterweight S5f under and, the float 86, causes the valve 87 to close. Since valves 82, 76 and 87 are closed and decompression is not created in chamber 79 then the fluid no longer passes and

the transfusion is stopped, 1sak if the level was reached (2,

As soon as these checks are completed, it is enough to re-screw the plug 77 onto the tubes 73 and the float 86

is lowered by opening the valve 76.
