SU26453A1 - Piston fluid meter - Google Patents

Description

Fluid meters with movable cylinders are known, in which pistons pushed by the fluid flowing into the cylinders are placed, which serve to release the cylinders from the stopper when they press the corresponding locking paws. In the proposed gauge, the studs, which fall into the axes of the gauge, serve the locking device, the upper ends of which are fixed in the disks, which are under the action of the spring.

In FIG. 1 shows a vertical axial section of the meter; FIG. 2- front view of the meter with a partial cut.

The gauge consists of four hollow cylinders 4, mounted on a cross 7, the central part of which is a conical sleeve, mounted on a conical axis - distributors 2, on which the cross can rotate along with the cylinders. The axis has two longitudinal channels a and e, of which the first has an exit upwards and the second down. When the crosses with cylinders are rotated, the latter through the channels 6, b, d, etc., present in the crosses, are alternately connected to the left (the position of the cylinder above), then to the right

channel axis-distributor (cylinder position at the bottom).

The work of the meter is happening, as follows. The measured fluid through the channels a to b enters the upper cylinder, while displacing the air from it through the holes in and the connecting pipe 2; air, filling the lower cylinder, drives the fluid contained in it through pipes // and 70 and further through channels d and 2 to the place of consumption.

Inside each cylinder there is a disk 5 with a drain stud 7 and a float 8. When the cylinder is filled, the float closes the holes s of the disk 5, the pressure is transferred to the disk and, overcoming the resistance of the springs 6, lifts it, compressing the spring. At this moment, the pin 7 fixed tightly with the disk 5 emerges from the socket in axis 2, and the entire system of cylinders under the action of the gravity of the left filled cylinder turns 90 ° in the direction (for the case shown in the drawing) opposite to the clockwise movement the device may rotate in one direction or the other, depending on where it will be given an initial impetus when it is put into operation after installation). The place of the upper cylinder will be occupied as follows.

   . / -,

behind him an empty cylinder and its stud / under the action of the spring 6 will lock the entire cylinder system for a while until it is removed from the socket under the action of fluid pressure, after which the entire cylinder system will again rotate by 90 ° and so the volume of fluid displaced the air pressure from the lower cylinder in the tube e is known, then by placing the rev counter 14, 15 at point 13 and knowing that the BeJiTb turnover corresponds to a certain amount of fluid, it is possible, by the meter readings, to take into account the entire flow. The amount displaced from the lower cylinder into the pipe. The fluid can be adjusted by the depth of screwing the tube / 7 into the pipe W.

Claims (3)

1. Reciprocating liquid meter with movable measuring cylinders fitted with stopper devices to keep the cylinders from rotating until the stopper is released by pressing the piston of a cylinder filled with liquid, which is distinguished by the fact that the locking device is designed as an employee & for alternately pushing into the recess of the axis 2 of the studs 7, which are provided with inlet 1 and outlet channels, fixed on the disks 5 placed at the end of each cylinder 4 and under the action of the spring 6. 2. When a piston liquid meter according to claim 1, the use of connecting pipes between two opposite cylinders of tubes 12, designed to pass air from one cylinder to another, in order to release the last one from LIQUID}. 3. When a piston liquid meter p. P. 1-2 application of exhaust pipes 7 /, i, placed in each cylinder, equipped with screw thread, with the aim of screwing them to different depths in the 1 W branch pipe fixed to the sleeve, in order to regulate the amount of liquid displaced.
