SU772972A1 - Device for sealing away the neck portion of fuel tanks - Google Patents

Description

The invention relates to measuring equipment and can be used in fuel dispensers.

A device for sealing the neck of a fuel tank is known, consisting of a dispensing valve mounted on a drain pipe, an elastic sealing element, a steam booster tube and a valve for communicating the tank cavity with the atmosphere [1].

This device is difficult in design, as it requires the additional use of an air compressor and three hoses connected to a fuel dispensing valve. about

The aim of the invention is to simplify the design.

To achieve this goal, the sealing element in the device contains a truncated cone, on the outer surface of which there are ring-shaped and located along the generatrix grooves, and a conical elastic cuff mounted on the cone, which is rigidly mounted on the cone from the side of its larger diameter, and the steam pipe is mounted in the latter, while the valve is mounted on a steam outlet pipe.

In FIG. 1 shows a fixture, general view} in FIG. 2 is a section AA in FIG. 1 .

The device consists of a dispensing valve fixed on a drain pipe 1, a sealing element containing a truncated cone 2, on the side surface of which annular grooves 3 and grooves 4 are formed, located along the generatrix of the cone located on the cone 2 of the conical elastic cuff 5, which is on the side of its larger diameter rigidly mounted on the cone 2 and mounted in the last steam outlet pipe 6 and valve 7 mounted on it.

The device works as follows.

The drain pipe 1 of the dispensing tap is inserted into the neck of the fuel tank, and the neck is partially sealed with a sealing element. When the crane is turned on, fuel enters the drain pipe 1 and the tank increases pressure, the fuel enters through the grooves 3 and 4 of the cone 2 under the sleeve 5, stretches it and completely

= 7, ^ 23.1 seals the neck of the fuel’’s tank. The vapor-air mixture is discharged through a steam exhaust pipe b either to the tank from which the fuel is taken, or to a device for vapor condensation. After the fuel is dispensed, the fuel tank through the valve communicates with the atmosphere to relieve excess pressure.

Using the proposed device will allow you to get an economic effect equal to a profiter ’but 3 thousand rubles per fuel dispensing column.

The invention relates to a measuring technique and can be used in fuel dispensers. A device for sealing the neck of a fuel tank is known, consisting of a dispensing valve fixed to the drain pipe, an elastic power supply element, a steam supply pipe and a valve for communicating the cavity of the tank with the atmosphere fl. This device is complicated in construction, as it requires the additional use of an air compressor and three hoses connected to the fuel dispensing valve. The object of the invention is to simplify the construction. To achieve this goal, the sealing element in the device contains a truncated cone, on the outer surface of which annular and located along the forming grooves are formed, and a conical elastic cuff fixed on the cone which is rigidly fixed on the cone on the side of its larger diameter, at the same time, the valve is mounted on a vapor discharge tube. FIG. 1 shows the device, a general VIEW} in FIG. 2 shows section A-A in FIG. 1. The fixture consists of a sealing element fixed on the discharge pipe 1, a sealing element containing a truncated cone 2, on the side surface of which annular grooves 3 are formed and grooves 4 placed along the generatrix of the cone 2 located on the cone 2 of the conical elastic cuff 5 its larger diameter is rigidly fixed on the cone 2 and mounted in the last steam discharge pipe 6 and valve 7 fixed on it. The device works as follows. A drain nipple 1 of the dispensing valve is inserted into the neck of the fuel tank, in this case a partial sealing of the neck occurs by a sealing element. When the crane is turned on, the fuel enters the drain pipe 1 and the tank increases in pressure, the fuel enters the grooves 3 and 4 of the cone 2 under the cuff 5, stretches it and completely seals the neck of the fuel tank. The vapor-air mixture is discharged through the vapor discharge tube 6 either to the tank, from where fuel is taken or to the device for vapor condensation. After the fuel has been dispensed, the fuel tank through the valve is in communication with the atmosphere in order to discharge the excess mass. The use of the proposed device will allow to obtain an economic effect equal to about 3 thousand rubles. on one fuel dispenser. Claim 1. A device for sealing the neck of the fuel tanks, consisting of a dispensing valve worn on the drain pipe, an elastic sealing element, a 7D4 steam outlet pipe and a valve for communicating the cavity of the tank with the atmosphere, characterized in that, in order to simplify the design, the sealing the element contains a truncated cone, on the outer surface of which annular and along the forming grooves are formed, and a conical elastic cuff fixed to the cone, which from its side the large diameter is rigidly fixed on the cone, and the vapor pipe is mounted in the latter. 2. The fixture according to claim 1, wherein the valve for communicating the cavity of the tank with the atmosphere is mounted on a vapor tube.
