DE436259C - Device for finding the liquid level in containers, especially for flammable liquids - Google Patents

Description

Device for finding the liquid level in containers, in particular for flammable liquids. For containers with flammable contents, z. B. Fuel for motor vehicles, are in all from (remote containers leading to the outside Pipes and vents sieves turned on to prevent the smack of a flame to prevent the inside of the container. Therefore, if by simple means, e.g. B. a rod, the liquid level is to be measured inside the container, so the sieve has to be removed at one point, which creates the risk mentioned. Carelessness on the part of the operator can also lead to forgetting to take the bearings to put the sieve back in again, or the one made of fine wire gauze and therefore delicate sieve - is made by the constant removal and reinsertion damaged so it. no longer offers security.

These disadvantages are eliminated by the device according to the invention, by creating a simple device consisting of strong individual parts is, which is always a bearing of the liquid level inside the container permitted and during or immediately after the direction finding, without special attention the operator to claim a sufficient closure of the interior causes the liquid container to the environment of the container.

The device is illustrated in the drawings, for example, It shows: Fig.-i a longitudinal section through the device (section after the Line I-1 of Fig. 2), Fig.2 a cross section through the device according to the Line-II-II of Fig.-i, Fig. 3 shows a longitudinal section through a somewhat different embodiment of the device, Fig. q. a cross section along the line IV-IV of Fig. 3, Fig. 5 shows the same cross section, but through a somewhat different embodiment of FIG Device, Fig. 6, a cross section through a liquid container with the Device according to the invention on a smaller scale and Fig. 7 is a cross-section by a dipstick for the embodiment according to Figures 3 to 5.

According to the invention is on a liquid container i (Fig. 6), whose liquid level is to be measured, a housing 2 attached through which a dipstick 3 i11 can be inserted inside the container. Inside this A bottom 5 inclined towards this opening is arranged around an opening 4 in the container. In the embodiment according to Fig. I, the housing 2 and the base 5 consists of a separate part each, both of which are secured by the fastening means for the device, z. B. screws or rivets, are united with one another. A closure body 6, e.g. B. in the form of a ball is provided, which is usually the opening 4 locks. Further closure bodies 7, 8 of the same design as the closure body 6 can be provided, the number being chosen so that the closure body endeavor to constantly urge a closure body towards the opening 4. It is therefore advisable to use two or three such closure bodies, on the other hand not several, since otherwise they can support each other in such a way, that no closure body comes to lie exactly in the opening 4 and part of the Ü therefore remains uncovered.

A guide part 9 is arranged on the housing, which guides the sounding stick exactly onto the opening ¢ when it is inserted and encloses this sounding stick with the smallest possible gap. According to the invention, the dipstick has a beveled surface io at the inlet end so that when it is inserted into the container in the direction of arrow I I it moves the closure body 6 in the direction of arrow I2 from the opening 4 and enters the container through the latter. Since both the bottom 5 and the guide piece 9 surround the dipstick with a very small gap, the interior of the liquid container is practically closed off from its outside environment during the plumbing. When pulling out the dipstick, one of the three closure bodies 6, 7, 8 immediately moves back towards the opening [and closes the same. In the embodiment according to FIGS. 3 and 4, a narrow housing 13 and in this a cylindrical closure body 14 is provided. In the embodiment according to FIG. 5, a spherical closure body 16 is arranged in such a narrow housing 13.

Since in the embodiments according to Figures 3 to 5 of the closure body not all-round; but is only movable in two directions, must be through appropriate Design of the cross section of the DF, z. B. of a sounding stick 17 in Fig. 7 and. a corresponding cross section of the guide part 18, care is taken ensure that the dipstick is always inserted into the container in the correct position will.

The guide part 9 or 18 can still be covered by a further protective cap i9 must be completed if a bearing is not to be taken, as shown in Fig. 3 indicated.

The device is also suitable for liquid containers, welehe with a protective, aas work, because despite the bearing a significant escape of the Protective gas is not possible.

Claims (3)

PATENT CLAIM: i. Device for bearing the fluid level for containers, especially for flammable liquids, by means of a dipstick, characterized in that at the container opening for the inlet of the dipstick, over which a guide part suitable for tightly enclosing the latter is provided is on a bottom surface surrounding the container opening and inclined towards it a closure body is movably arranged in a housing, so that upon insertion of the dipstick, which is provided with a beveled end for diesel purposes, of the closure body is moved away from this to release the insertion opening. 2. Device according to claim i, characterized by several, e.g. B. two or three closure body, which the Support rolling back one of these onto the container opening. 3. Device according to claim i, characterized in that the base carrying the closure bodies (5) and the housing (2) covering the closure body consist of separate parts, which are held together by the fastening means of the device.
