N. M. Antukov (71) Applicant (54) DEVICE FOR REGULATING THE LEVEL AND DRAIN OF LIQUID

The device is intended for filling, level control and drainage of lubricating and preserving fluids and can be used to accurately control the level of fluids of different purposes when used repeatedly in removable containers of various volumes, for example, when running mechanisms.

A device for regulating and draining a liquid containing a measuring tank with a drain pipe, a tank with a float, a level gauge and a connecting pipe [1].

The disadvantage of this device is the lack of precise control of the liquid level with convenient control

The purpose of the invention is to improve the accuracy of regulation of the liquid level.

For this, the float is installed obliquely to the horizon on the connecting pipe and is made integral with the level indicator, and the drain pipe of the measuring tank is equipped with a sleeve that is adjustable in height, the sleeve is equipped with a hollow rod.

Figure 1 presents the device, a General view; figure 2 is a section aa in figure 1.

Capacity 1 is mounted on a fixed stand for running-in and mounted on supporting surfaces, from which, as from the base, a folding horizontal ruler (not shown) is pivotally fixed, which determines the new minimum position of the liquid level.

A nozzle 3 with an inner cone and an end bevel is installed to the drain hole 2 of the tank, to which a distributor 4 with an outer cone and a bevel of a lesser slope adjoins, having a groove 5 with a hinged part for draining residues of different liquids. 20 wherein the seal 6, located between the bevels, is pressed by a screw pair 7, which can be displaced in the plan. The float 8 has a level indicator 9, which forms part of the wall 25 of the latter, and a latch, position 10, connected with the grooves on the stand, is connected to the connecting pipe of the L-shaped form 11 with the packing gland and compression nut 12. Tanks

13 for heating the fluid to a certain temperature are connected by pipes 14 to measuring tanks 15 (separately for preserving and working fluids), equipped with drain pipes 16 and movable sleeves 17, adjustable in height by means of screw pairs 18, made with hollow rods for communication with atmosphere when filling containers of various volumes. Each measuring tank 15 by pipelines 19 with shut-off valves 20 is connected to a float 8, equipped with drain valves 21, through which the grease is drained (in position I) into the funnel 22, and the preserving liquid into the funnel

23.

The shut-off valve 24. Is installed in front of the fitting 3 only if the mechanism is sent for power tests.

The device operates as follows.

The working fluid (or preserving) is heated in the tank 13 to a certain temperature and is pumped through the pipes 14 to the measuring tank 15. The movable sleeve 17 of the measuring tank 15 is adjusted by screw pair 18 to a predetermined volume of the tank. Excess liquid flows through the drain pipe 16 into the tank 13. A fitting 3 is installed in the drain hole 2 of the tank 1, which has an inner cone with a bevel at the bottom, designed to guide the distributor 4 with an outer cone, below which there is a bevel with a more gentle slope than the nozzle 3. Under the action of the preload 7, the connection is self-installing and centering, and the seal 6 is pressed to the center and the bevels and cannot be flattened, since the bevels of the nozzle 3 and the distributor 4 have different * bevel angles and there always remains between them space occupied by compaction. The stuffing box packing 11 is tightened with a nut 12. After opening the stopcocks 20 through the tubes 19, the crankcase is successively filled with working fluid by gravity and, after running in, with preservative fluid.

For oil break-in by the mechanism, it is necessary to maintain the oil level within tight limits (+ 2 mm) according to technical specifications.

The required amount of liquid cannot be accurately measured with a measuring tank, since each container of the same size during manufacturing has deviations in the internal volume due to inaccuracies in casting.

From the measuring tank, the optimum amount of liquid is received, which is necessary for running the mechanism, taking into account the float 8 and installed by the movable sleeve 17 for a given volume of the tank

1. The exact final level setting is made up to the float for 8 s, by angular rotation to the right (position 11} or to the left.

If the oil from the float 8 is poured into the tank 1, then the oil level in the latter rises, if from the tank 1 into the float 8, the oil level in the tank decreases.

After the final installation of the oil level, the float 8 is fixed with a latch 10.

After running in the mechanism, the grease is drained through the taps 21 into the funnel. 22 (position I) or into the funnel 23 by turning at a certain angle of the float 8.

In this case, when turning right, the left crane opens, and when turning left - the right one. When removing the tank, the remaining liquid flows down the trough 5 with the hinged part into different funnels (not shown), depending on the purpose, and by gravity is poured into the corresponding containers for separate filtration with cleaning and reuse.

During power tests, a crane 24 is pre-installed, which is locked after running-in and, at the end of the operation, drain and preserve.

Using a device for regulating the level and discharge of liquids, not only mechanically accurate and nominally mechanized filling and discharge of mechanisms of various capacities is ensured, but also filling with different types of liquids with compactness and ease of use when running in serial production.

Claims (2)

divided temperatures are connected by pipes 14 to measuring tanks 15 (separately for preservative and working fluid), equipped with drain pipes 16 and movable sleeves 17, adjustable in height by means of screw pairs 18, made with hollow rods for connection with the atmosphere when filling the tank different volume. Each measuring tank 15 has pipelines 19 with shut-off valves 20 connected to the float 8, equipped with drain valves 21, through which the lubricant is drained (in the O position to the funnel 22, and the preserving fluid is installed in the funnel 23. The stop valve 24 is installed before fitting 3 only when the mechanism is sent for power tests. The device operates as follows: The working fluid (or preserving fluid) is heated in the tank 13 to a certain temperature and pumped through pipes 14 to the measuring tank 15. The movable sleeve 17 of the measuring tank 15 adjusts the screws A pair of 18 to a predetermined volume of the container. The excess liquid through the drain pipe 16 flows into the tank 13. In the drain hole 2 of the tank 1, a fitting 3 is installed, which has an inner cone with a bottom at the bottom to guide the distributor 4 with the outer cone below which a slant with a gently sloping slope than that of nozzle 3. Under the pressure of the clamp 7, the joint is self-adjusting and centering, and the seal 6 is pressed against the center and of the slope and cannot be flattened, since the slope of fitting 3 and the distributor 4 have different angles and between them there is always a space that is occupied by compaction. The gland seal of the connecting tube 11 is tightened with a nut 12. After opening the valves 20 through pipes 19, the crankcase sequentially fills the working fluid by gravity and, after running in, with a preserving fluid. To run the engine through the oil, according to the technical conditions, it is necessary to maintain the oil level within tight limits (± 2 mm). The required amount of liquid cannot be accurately measured by mercury number 1 with a tank, since each container of the same size during fabrication has a deviation in internal volume due to inaccuracies in pouring. The optimum tank receives the measured amount of liquid required for the mechanism run-in, taking into account the float 8 and set movably by the tulkula 17 for a given volume of the tank. A precise final installation is made before the float is 8 seconds. by means of an angular rotation, its right (position II) or to the left. If the oil from the float 8 was poured into the container 1, the oil level, the last one, if from capacity 1 to the float 8, then the level of the asla in the tank decreases. After the final setting of the oil level, the float 8 is secured with a latch 10. After the mechanism is run-in, the lubricant is drained through the taps 21 into the funnel. 22 (position I) or into the funnel 23 by turning the float 8 to a certain angle. At the same time, the left valve opens when turning to the right and the right valve when turning to the left. When the tank is removed, the remaining liquid flows along the chute 5 with the flap part into different funnels (not shown), depending on the purpose, and by gravity flow into the corresponding tanks for separate filtration with cleaning and reuse. During the power tests, a crane 24 is pre-installed, which is locked after running in and at the end of the operation the drainage and preservation are performed.
