Description

Liquid meter for measuring a specified amount of liquid, made in the form of two measuring vessels, rocker arms with a locking mechanism connected by valves to vessels of valves and floats to release the locking mechanism when filling the vessel, and supplied with a counter of the number of fillings of the measuring vessels are known.

The disadvantages of such fluid gauges are fuzziness in operation and the complexity of the device.

The liquid described above is devoid of these drawbacks due to the fact that the rocker mechanism of the rocker arm consists of a rotary outfit P1x x at the ends of the rocker arm of the levers that interact with the latches of the rocker arm and with the rods of the floats when the vessel is filled.

To stop the supply of fluid after measuring a predetermined amount of fluid, a valve is installed on the inlet pipe of the fluid meter. The valve is controlled by a camshaft mounted on the same axis with the ratchet, which interacts with a T-shaped swivel link connected with the rocker arm.

The drawing shows a schematic fluid meter.

The fluid meter consists of two measuring vessels 1 and 2, provided with inlet ports 3 and outlet ports 4.

Outlets 4 are opened and closed by valves attached to tam 5, which are connected to the rocker 6, and inlet ports by 3-valves 7 mounted on a T-shaped swivel 8, connected by links 9 to the rocker 6.

Between the measuring vessels 1 and 2 is located the inlet pipe 10, through which the liquid enters either the vessel 1 or the vessel 2.

At the ends of the rocker arm 6, the rotary levers And and 12 are installed, which interact with the spring-loaded No. 97963-2 - mounted on the suspensions

with 13 snaps 14, on the lower ends of the carriers of nonlavki 15, placed inside the measuring vessels 1 and 2.

For a fluid enne supply to vessels 1 and 2, after measuring a given quantity of it, the inlet pipe Guo is equipped with a valve 16, the holder 17 of which is attached to a freely rotating sleeve connected to a lever 18, having a latch 19 at the end, with a pincer 20.

Dog 20, hooking on the ledge of the winding cam 21, fixes its position ..,,

In the slot of the T-shaped swivel driver 8, the end of the driver 22 of the lever 23 having a dog 24 turning the ratchet 25 is inserted. The latter is mounted on the same axis with the cam 21 and the pointer of the scale gauge.

On the lever 18 vertically attached rod 26 with a load of 27.

At the lower position of one of the floats 15, for example, in vessel 1, hole 3 is open and hole 4 is closed and liquid fills vessel 1. Float 15 rises and there comes a moment when the pull 14 presses the rotary lever 11, resets the trim 3 and raises yoke At this moment in the vessel 1, the opening 4 is opened, and the opening 3 is closed by the valve 7 and the liquid is expelled from the vessel 1, and at the same time the filling of the vessel 2 occurs.

When swinging the rocker arm, the leash 8 each time through the lever 23 and the dog 24 turns the ratchet 25 on one tooth; at the same time, the cam 21 and the pointer of the scale gauge turn.

After a liquid quantity of liquid, the pawl 20 disengages the protrusion of the cam 21, the latch 19 jumps off the pawl 20, and the lever 18 under the action of the load 27 is lowered, turning the sleeve with the valve (the bushing 17, and the valve 16 closes the opening of the vun tube 10.

To re-measure the fluid, the crown 21, the pawl 20 and 18 is set to the initial position.

The number of no-swept through the fluid liquidometer is taken into account by the counter (not shown in the drawing), the connections are made by means of the rod 28 with the rocker 6.

Subject invention

1. Liquid meter for measuring the specified quantity / liquidity, made in the form of two measuring vessels, rockers with a locking mechanism, connected by means of valves to the valves, and floats to release the locking mechanism during the recording of the vessel and equipped with a counter for the number of fillings of the measuring vessels, l and h and hI and with the fact that, with the aim of pov11 and clarity of operation of the zagyorny mechanism of the rocker arm and control of its device, the most recent consists of pz of the levers interacting with the latches of the rocker a and c t gami nonlavkov nri fill the vessel.

2. Liquid meter on c. 1, characterized in that. that, in order to stop the supply of fluid after metering, it is set to the south of its quantity, a clan is installed on the inlet pipe of the fluid meter, controlled by a winding cam, mounted on the same axis with a ratchet, interacting with a T-shaped nozzle, connected to the rocker arm.
