SU13642A1 - Two-chamber water meter with rocker distribution - Google Patents

Description

BACKGROUND OF THE INVENTION The invention relates to dual chamber water meters with a beam distribution controlled by two floats. In the proposed water meter, the water inlet to its measuring chambers is controlled by a spool connected to the rocker, to the ends of which the floats are attached. The latter are connected by flexible cables with upward opening valves which sit in the sockets of the measuring chambers, the measuring chambers and are equipped with appropriate guides. The measuring chambers communicate with each other with a pipe, the ends of which are provided with sockets for ball valves and are covered with trellised funnel-shaped kolkamps.

The drawing shows a vertical section of a water meter, consisting of two measuring chambers S, S, the lids of which are fitted with glands 5, 5j, with a passage through them through floats L, L. The latter are connected to the upper arm with the rocker K pivotally connected to the lever N carrying load N and spool 25, which is changed in chamber B, connected to water supply pipe J., and has the ability to close or open the inlets of pipes C, C, respectively, connecting measuring chambers 8, 8 to chamber B Bottoms of chambers 8,8 are provided with holes forming a The nests of clans b, 6, which are connected by flexible cables to the floats L, L and are fitted with guides 8,8 placed in the tube 10. The latter communicates the chambers 8, S and the valves 9, 9, which serve to guide water into the drain pipe 12. In addition, the chambers S and / S communicate with each other by means of a pipe M, the ends of which are made in the form of nests intended for ball air valves d, d and are covered with trellis funnel-shaped caps.

Water through pipe A enters chamber B, from where it passes through spool 25 and pipe C, enters measuring chamber S ,, filled it. In this case, valve 6j is closed, and valve 6 is open, whereby water, which is P1, and with the pressure of air displaced from chamber 8 into chamber S through pipe M, flows into pipe 10 and from there through valve 9 goes to drain pipe 12. When the water level in chamber 6 rises to pipe M, the spherical air valve g closes it and thereby stops the entry of air into chamber 8, due to which the water entering chamber S, under pressure, will increase the pressure in it, and the float bj will begin push out. I act on the yoke K, the float will move the spool 25, which will close the access of water to the pipe (7j and open it into pipe C. This will open clan 6, and clan 5

closes, whereby the chamber S begins to fill with water, and the chamber S discharges from it.

The subject of the patent.
