Description

The invention relates to devices for taking an average sample of oil from hermetically sealed tanks, wherein said devices consist of gas and oil pipes connected by their lower ends to vessels for receiving samples. In the proposed device, the oil on the pipe is made in the form of a telescopic pipe, the lower link of which, with its upper part, communicates with the cavity of the upper link, and in the lower part has a bottom with a hole, overlapped by a sleeve with a tube, for draining the sample from the oil pipe.

In FIG. 1 shows a general view of a device installed in a tank; FIG. 2 is a vertical section of it; FIG. 3 is a view of a vessel for taking an average sample.

The device (figs. 1 and 2) consists of two pipes (gas and oil) placed in a hermetically sealed reservoir and attached to the vessels for receiving samples by their lower ends. The oil in the pipe is made in the form of a telescopic pipe, the lower link 1 of which is provided in the upper part with holes 20 designed to communicate the cavity of this link with the cavity of the upper link 2 tightly covering link 1. The marked links are mounted on a common rod 3 and can move towards one another: lower link 1 - from

the middle of the tank to cover it and link 2 from the same place to the bottom of it. Rod 3 consists of a rod in the lower part and a deaf tube in the upper part. The rod is fixed on the lid and bottom of the tank using a tripod 4.

The lower link 1 slides along the rod 3: at the bottom - with the bottom with the hole 5, up the walls against the sealing ring b. Link 2 at the top slides with a bottom with a hole 7, and below with a sealing ring 8 along the walls of link 1.

The bottom with an opening 5 is blocked by a sleeve 22 with a tube 23, which is intended to discharge the sample from the oil pipe through the valve 24 to the vessel 25 (Fig. 3). The latter consists of a can or a glass jar 26, through which a wide cork 27 of oil is passed through and a gas tube 28 with faucets 29.

To raise the upper link 1, there is a cable 9 attached to the hook 10 and slung over block 11 (Fig. 2). The lower link 1 is lifted by cable 12 with hook 13 and block 14. Cable 9 is wound by a coil drum 15 with an end of an axis 15 extending outside the tank. The cable 12 is wound around the drum 16. Both drums have one removable handle 17. For a looser sius link, the links are provided with counterweights 18 and 19.

To take an average fluid sample.

The lower link 1 is raised and lowered and then lowered and the upper link 2 is raised. When the outer pick valve is lifted, the line is lowered (the bone will begin to descend simultaneously into both links x. At the same time, it goes from the upper link to the lower one ( holes 20 in the latter), then into the sleeve 21 with a conical socket (with sleeve 22) for the conical bottom of the link. The sleeve is fixed on the tripod 4 and the tube 23 connects to the external crane 24.

When taking the fed sample, the links are filled and vessel 25 is supplied under the valve 24 (Fig. 3). By connecting the oil taps 24 and 29 with an elastic tube, they are opened and held in this position until fex oil is poured into the vessel. If for some reason the liquid from the links does not flow (small tank size, high sampling, low pressure, low tank filling), then connect the gas tube 28 of the vessel 25 to the tap 30 of the gas tube 31 of the tank.

For private sampling, two vessels are used, one of which must be graduated or labeled. The vessels are connected to the crane 24 by means of a tee 32 with tubes 33. (Fig. 3). Having lowered into the graduated vessel the amount of liquid corresponding to the desired height, let some

its quantity and another vessel, having opened a faucet 29, having previously closed the 1Franik at the first vessel. - The residue of the liquid in the units is either left in them, or drained (secondarily) in a graduated vessel. If the liquid in the tank is more than half, then a private sample can be obtained in the following way: lowering the upper link, raise it to the desired height, considering the number of revolutions of the roll. Having lowered into one vessel the amount of liquid remaining from the previous sample or leaked through the gasket of the sleeve or ring of links, transfer it to another vessel.

Subject matter.

A device for taking an average sample of oil from hermetically sealed tanks, consisting of two gas pipes, and an oil one, connected by lower ends to vessels for receiving samples, characterized in that the oil on the pipe is made in the form of a telescopic pipe, the lower part of which has in the upper part of the hole 20, designed to communicate the cavity of this link with the cavity of the upper link, and at the bottom - days with the hole 5, blocked by a sleeve 22 with a tube 23, designed to discharge the sample from the oil pipe.
