SU16923A1 - A device for determining the amount flowing through a steam or gas pipeline - Google Patents

Description

Known are methods for determining the amount of a gas ELE gas flowing through a pipeline, which are connected to the pipeline on both sides of a conventional branch choke washer, and the liquid to be directly measured is circulated to the bed. In such a device, it is proposed to include a piston cataract, the piston of which is washed on both sides with liquid, and the end surfaces of the rod perceive the pressure of vapor or gas.

The drawing shows a plot of the proposed device.

Piston cataract A is filled with fluid that washes piston D and is fitted with a stem B and which passes through the sealing glands FI and FZ into the cylinders DI and DZ. The latter are connected to the pipeline on both sides of the throttle washer, at which they can be switched: if at first Di was soaked in front of the washer, and D2 in the back, then after switching they change places. The fluid enclosed in cataract A can pass from one side of the piston to the other through an opening in the body of the piston or through the gaps between the piston and the cylinder. With this

When the fluid transitions, the position of the piston in the cylinder will change and indicate the amount of steam that has passed through the washer. When the extreme position is reached mechanically or electrically, cylinders D and D are switched, and the piston begins to move in the other direction. Determining the position of the piston and the number of its strokes can be done in various ways, for example, with a glass window in the cylinder wall and a stroke counter. To reduce errors from inaccurately horizontal installation, the piston B and the rolling pins D and B must be balanced by the fluid they displace.

The subject of the patent.

1. A device for determining the amount of steam or gas flowing through the pipeline, consisting of a conventional branch throttle washer attached to the pipeline on both sides, in which the fluid to be measured is circulated, characterized by the fact that the branch includes piston cataract A ,. the piston of which is washed on both sides by liquid, and the end surfaces of it are sealed in the glands Ji, FZ of the stem D, D are designated for sensing vapor pressure or

gas.

Ill 2. Modifying the characterized "n, 1 device, characterized in that the ends of the branch are connected to the pipeline by means of a switching body, in order to return the piston B to its original position, as well as to use the return stroke of the norpsh to read the liquid passing through the cataract .
