Description

The invention is a type of liquid meter consisting of a measuring cylinder with a free piston in it to displace the cylinder of the measured liquid through the drain window. At the extreme part of the cylinder, the pressure of the liquid entering the cylinder through the window located at the other extreme part of the cylinder during automatic switching of the multiport a distribution crane, each turn of which is taken into account by a counter connected to it.

The novelty of the proposed device is seen in the device that automates the operation of the crane.

FIG. 1 of the drawing shows the device in cross section along the axis of the edge; FIG. 2 is a longitudinal section of it, and FIG. 3-view of the counting mechanism.

The device consists of a bed / in which there is a four-way stuffing valve with a conical plug 2, and a measuring cylinder 3 fixed to this bed, covered with covers 4, with a piston 5 placed inside, and a counting box 6 adjacent to them with a cover 7, .

In the caps of the measuring cylinder, the plugs 8 are screwed on the threads, with which the volume of the cylinder is adjusted (calibrated) to limit any accuracy limit by limiting the flow of porUn.

(217)

A sleeve P is inserted into the opening of the rear wall of the box b with the possibility of rotation, having a recess in the outer end for square 2 of the plug 2. The opposite end of this sleeve is drilled for the end of the roller JO.

On the sleeve 9, the ratchet sprocket //, the anchor sprocket J2 and half of the cam clutch / 5 are pressed in. The second part of this coupling slidably sits on the roller / L Pin J4 keeps this coupling half from turning on the axis 70, and the spring / 5 presses it against the part 75.

Closer to the lid 7, a drum / 5 is fixed on the roller 70, on which one end of the winding spring 77 is fixed. The second end of this spring, riveted in the form of a loop, is held by a pin in the lug 18.

In addition to the winding spring, the gear 76 is tightly pressed on the drum 76, which interlocks with the toothed wheel 27 mounted on the axis 20, which is the dial of the discontinuous counter with the numbers 5 on it. 70, 15, 20, etc., to the desired limit, depending on which gear ratio of this pair of gears is selected.

A ratchet asterisk.77 matches a doggie 22, which transmits its motion to a total reel counter 23.

The rotation of the anchor sprocket 12 is controlled by the anchor arm 24, freely seated and (on the axis 20 and placed between two diaphragms 25, the cavities of which communicate with the cavity of the cylinder 3 via tubes 26 and tapping channels 27).

The roller 10 at the front ends with a thumb 2. The dial 2 / on its back has a locking protrusion 29, which corresponds to the stop of the box 30.

To bring the monobLock into operation, the butterfly 28 is rotated in the direction opposite to the clockwise movement, until in the round box of the box of the calculating mechanism the figure corresponding to the given (to the tempering, the amount of liquid (in liters)) is obtained. up to a certain voltage; wherein the roller 10 rotates freely in the opening of the sleeve 5, while the sleeve itself and the plug of the crane 2 held by the pawl 22 remain stationary.

After setting the dial 2 / to the position indicated above, the fluid to be measured is passed through channel A under a certain pressure (from a pump or static pressure).

The fluid, having passed the four-way valve, is guided, as indicated in the drawing, along the right channel and fills the discharge channel 27, tube 26, diaphragm body and measuring cylinder cavity between the right cover 4 and piston 5. Under the pressure of the liquid piston 5 from its rightmost The position is forced to move smoothly to the left before meeting with the cork of the left cylinder edge. At the moment of the piston stopping, the fluid, continuing to flow into the cylinder, will create a hydraulic shock, under the influence of which the diaphragm 25 will bulge outwards and push the balance arm 24 to the left, thereby releasing the anchor sprocket / 2, which under the action of the spring / 7 together with the roller 10, the bushing 9 and the stopper 2 will turn in the direction of movement of the clock at an angle of 90 °, which will entail channel switching, and the liquid will begin to flow into the left part of the cylinder 3 and push the piston 5 aside.

to the right. Under an unpressurized piston, the fluid on the right side of the cylinder will be forced out through the discharge port B.

Simultaneously with the rotation of the sleeve 9, the pawl 22, under the action of one of the teeth of the ratchet sprocket //, will be rejected downwards and this movement will bring the total counter 23 into operation.

The described cycle will be performed in the specified order until the figure O appears in the window or, which is the same, the meeting of the locking protrusion 29 with the stop 30.

Present invention.

 1. An apparatus for discharging liquid in measured quantities, consisting of a cylinder with a free piston, the stroke of which is regulated by the plugs screwed into the cylinder heads, filling and, at the same time, emptying of which occurs with the automatic, spring-loaded switching of a multi-way distribution valve to indicate, in volume units, the amount of liquid passed through the apparatus,

wherein the anchor 24 of the latter is actuated by diaphragms 25 mounted on the sides of its rocker, which perceive the excess fluid pressure due to the filling of the measuring cylinder and are intended to disengage the said anchor with the anchor asterisk 12 mounted on the crane plug.

2, the embodiment of the apparatus according to claim 1, characterized in that the dial 27 is engaged with the gear 19 on the winding roller 10 and is designed to stop the spring deployment and, therefore, to terminate switching the crane by engaging its pin 29 with an emphasis 30 on the mechanism box body.

3. In the apparatus according to claims 1 and 2 applications of the end of the ratchet coupling / 3, used for coupling the roller 10 of the spring with the plug of the crane 2.
