Description

The invention relates to liquid sealing applications for dry gas holders using a liquid that is located in an annular chamber that is open towards the walls of the reservoir.

In the proposed device, in order to maintain a constant level of fluid in the chamber, the chamber, in addition to communicating with the gas space under the piston, is connected by two tubes to a reservoir containing a supply of sealing fluid under pressure corresponding to the pressure of the gas in the gas holder.

The schematic drawing shows a vertical section of a liquid sealing device for dry gas holders.

The gas cylinder piston is provided with a sealing device in the form of a collar 3, which is pressed by the gas pressure in the space A to the gas cylinder clamp B. In addition to the gas pressure, the aerotnik 3 is under pressure from the pressing device 4. The pressure exerted on the gate 28 nick 5 can be increased or decreased, depending on the working condition, by pressing the screw on the spring of the pressing device.

Above the collar 3 at the wall of gas holdea there is an annular chamber 6 with a liquid, connected by a pipe 8 with a gas space A under the piston.

The fluid in chamber 6 is constantly under pressure from the gas inside the gas-holder. To balance this pressure, a barometric tube 9 is used, the height of which is designed for the greatest pressure inside the gasholder. The sealing lips JO, 11. of which the latter is provided with a pressing device 72, prevents the liquid from being squeezed out of the chamber b by the force of gas pressure. Tape 10 may be removed from the opening. veneered plywood, the sheets of which are bound by an elastic, fluid-tight compound.

Chamber b by means of tubes 13 and 14, which are below the liquid level c.

it is connected to a hermetically closed reservoir / 5, which contains a supply of tight fluid.

The tube 14 connects the tank 15 to the chamber b in the lower part and creates a current of fluid, and the tube 13 goes out with one hole slightly below the level of the fluid in chamber 6 and the other hole into the tank lid 75, into its air space. The liquid level in the tank 7-5 should be equal in height to ypoaHjo created by the pressure of the gas-holder gas in the tube 9, according to which the height of the tank 15 should be selected.

In the case of lowering the level of liquid in chamber 6 below normal, the opening of tube 13 opens, and gas from space 7 above liquid in chamber 6 enters the hermetically sealed reservoir 15, and the liquid from the latter through tube 14 enters chamber 6. Once the liquid in the chamber 6 will reach its normal level, the opening of the tube 13 with this liquid. it closes, gas supply to tank 15 stops, pressure in whom is lost, and the liquid stops flowing into chamber 6.

The reservoir 15 is provided with an inlet tube 16 for replenishing the liquid reserve.

tube 77 for discharging gas when pouring, glass 18 for checking the level of the liquid in the tank and tube 19 for discharging the liquid and cleaning the tank from foreign contaminants that could get into it. All tubes of the tank 15 are provided with valves and taps.

Pr.dmet invention.

1. Liquid sealing device for dry gas holders using liquid located in an annular chamber open toward the tank walls, characterized in that in order to automatically maintain a constant level of liquid in chamber 6, the chamber is communicated on one side with gas space A under the piston, and on the other hand with the reservoir 75, which contains a supply of sealing fluid, and is equipped with a barometric pipe 9 communicated with a piston; space, in order to balance the gas of the vania in it. 2. An embodiment of the device according to claim 1, characterized in that for connecting the tank 15 to the chamber 6 are tubes 13, 14, of which the tube 13 communicates chamber b with an airspace; tank 75, and the tube M with liquid in this tank.
