SU43296A1 - Liquid meter with an automatically locked valve at the time of its filling and emptying - Google Patents

Description

Liquid gauges are known with valves that are locked during filling and emptying by means of bolts moved by floats, using counters for recording the amount of liquid passed by the gauge.

The proposed liquid meter is a variation of the above-mentioned instruments for measured liquid dispensing and differs from them in that the valve, which blocks the air passage, and the bolt, which stops the valve, is controlled by one float.

FIG. 1 shows a meter in longitudinal section along the axis of a crane; FIG. 2 is a view of it from the side of the counter with a partial cross-section of the crane.

The liquid meter consists of a glass or metal measuring cup 23 fixed on the body II of the crane and covered with a lid on top. The lid is a obturator 3 with a disc lid 25 fastened to it by means of bolts 2 and entering into the inside of the glass. Disc cover,

The central bushing, which is in the center, serves to strengthen the valve 4, which is designed to control the transfer of air from and to the gauge when filling and emptying the cup 23 with liquid. The measuring cup communicates alternately with the reservoir that feeds it with liquid and the drain pipe 24 by means of a three-way valve 11. Inside the glass there is a tube 8 not reaching the lid 25, intended for the direction of the float 7. Inside the tube 8, fixed to the body of the crane, the rod 6 passes terminating at the bottom with a transom 12, locking the valve 1b during the emptying and filling of the measuring cup 23.

The rod 6 at the top and bottom has fingers 5 and 9 located in mutually perpendicular planes passing through the wings in the walls of the tube 8. The float 7 picks up the fingers 6 at the top with the liquid level and moves it up removing while the bolt 12 of the socket plugs 16 of the crane, which allows the seller to switch it. At the same time, the rod 6 closes the breather valve 4, the shank 1 of which is guided by the sleeve of the cover 25.

The tube 8 in the lower part is equipped with a pair of hinged levers 10, whose short and inward tube arms are designed to fill the lowest lower position with the float 7 and lift bolt 12 again with their action on the lower finger 9 of the rod 6, which gives the seller the opportunity to switch the plug 16 again the crane.

The operation of the meter proceeds as follows: when turning the plug 16 of the crane And by the handle 13 counterclockwise, the measuring glass is connected through the nozzle 14 to the reservoir that feeds the liquid, from which the liquid is supplied under pressure or by gravity. The liquid raises the float 7; the latter, reaching the extreme upper position and acting on the fingers 6, lifts the rod 6 and releases the plug 16 of the valve from the bolt that stops it, and at the same time the prohibition of the air passage valve. The beaker is filled with a certain amount of liquid and the seller can drain it into the consumer by turning the tap of the valve, which is released from the bolt that stops it during filling. As soon as the liquid begins to pour out through the drain pipe 24, the liquid level in the measuring glass will drop, the float 7 will lower with it, as a result of which the rod 6, with its weight also down, releases the valve 4 and the latter opens, giving access to the air in the measuring glass. The bolt 12 will then enter the second socket on the plug 16 of the crane and warn you of the possibility of switching it. By freeing the measuring cup from the liquid

the float 7, placed in the lower position in the glass, presses the long shoulders of the levers 10 and causes them to move downward. The short shoulders of these levers, turning up and acting on the finger 9, cause the rod 6 to move up. The bolt 12 will come out of the tap plug socket, which will make it possible to switch the tap to fill the meter. In the future, the process of emptying and filling the measuring cup will be repeated in the same order. When turning the plug of the valve through the lever gear 17, 20, the counter 22 is activated, recording the amount of fluid passed through the meter.

The lever 20 is closed by a casing 21. A crane 11 by a fitting 15 is screwed to the counter. A pipe is connected to this fitting from the supply tank.

The subject matter of the invention.

A liquid meter with an automatically locked valve for the time of its filling and emptying, consisting of a measuring vessel with a three-way distribution valve and a float enclosed in it, characterized in that to control the valve blocking the air passage channel and the deadbolt that stops the valve, using one and the same float, the bolt 12 and the valve are fixed on the common rod 6, which is enclosed in the guide float pipe 8 and provided at the top and bottom with fingers 5 and 9, intended to move this rod in the vertical direction in order to release the plug 18 of the crane 11 from the deadbolt blocking it, by acting on them directly and through the swivel levers li of the float 7. to the author's certificate of M.
