Description

The proposed modification of a device for sampling liquids from closed tanks mentioned in the patent. No. 11861, characterized in that the rod with the valve is replaced by a hollow cylinder placed inside the pipe, equipped with two openings for the inlet and outlet of a fluid, coinciding with the corresponding openings of the same purpose in the pipe.

In FIG. 1 shows a general view of the device; FIG. 2 is a longitudinal section of it; FIG. 3 - side view; FIG. 4 is a front view; FIG. 5 and 6 — handle device for control; FIG. 7, 8 and 9 is a cross section of the device.

The device consists of the following three parts:

1) from tube A (fig. 2), screwed into the tank wall at those heights from which they wish to take samples. Tube A consists of 2 separate tubes of different diameters inserted into each other. The first has one end embedded and is a cover for the second. The second tube has both ends embedded and thus represents a special balloon. The balloon (Fig. 2) rotates inside the casing with the aid of / missed h (the rod K supplied with (Fig. 4) with the lever P, through it. To facilitate friction, the balloon contacts the casing walls only with thickened, carefully ground ends. Cylinder and casing (Fig. 7, 8, and 9) are provided with matching inlet 1 and 2 and outlet 3 and 4 openings.

2) from a collection tube B (Fig. 2) located vertically along the wall of the tank and consisting of separate parts that are bolted together.

3) from the coupling D connecting (fig. 2) tube A with tube B. At the junction of tubes A with the collecting tube B, there are sockets on the latter, which include the outer ends of the tubes A. Additional attachments are (Fig. 4 and 5): lever П, cable L, spring Ж and handle - / W located at the bottom of the tank.

The operation of the device is as follows. To take a sample from the tank, the handle M is moved along the arc to the point “inlet”, and during this movement the cable L will turn the lever P, put on the rod K, as a result of which the balloon inside the pipe A will assume such a position when its opening 2 is aligned with the casing hole 1 and the liquid from the reservoir will be transferred to the cylinder in an amount equal to its volume.

To release the liquid from the cylinder to the collection tube B, the handle G is moved to the release position, with eetrum, the outlet openings 1 2 are uncoupled, the cable L will weaken somewhat and the lever L by means of the spring Ж will cause the balloon to be in this position A match and the liquid from the container will pour into the collection tube B.

After releasing the liquid from the cylinder, the handle M is moved to the “closed” position, at which the cable L will weaken even more and with the force of the spring Ж the lever P will bring the cylinder to that position.

when the holes 7, 2, J and # turn out to be disconnected and therefore closed.

subject matter of the invention.

Modification of the device: for sampling liquids from closed tanks, designated in the Fe 11861 patent, characterized in that the rod d with the If valves is replaced with a hollow cylinder B placed inside the pipe A and provided with fluid inlets 2, 3 corresponding to openings with 1 ton 4 of the same value in the pipe.
