SU601669A1 - Liquid pressure and level regulating device - Google Patents

Description

In the drawing, the image | pr: e, is a hollow device in general view with partial machine tools.

The operation for 1 rely, an “pressure” and “liquid level” consists of BAKOV-a.kkumul tor / I 2, hermetically separated by a partition 3, .Vertical pipes 4; and 5, connected to the bottom “: their bottom and bottom of ayukumultrav tanks, (vertical pipes 6, fitting 7 for supplying fluid (Liquid, connection pipe 8 for supplying steam, .pipe 9, valve 10, .pipe //, fitting 12 for draining the liquid, fitting 13 for pressure relief. and vents 14, 15 .

The device is installed on the plate 16.

A fitting 7 for supplying a liquid with a device is connected to the water volume, and latrubokad 5 for the supply of steam to the first space of the aiaparate. The device is installed so that the nozzle 12 draining the fluid was at the same height with the level of fluid IB device. Firstly, the liquid is filled with fluid through the oil L5 to the level of the socket 12.

The device works as follows. I | m obra) M.

 overpressure, .raVYY M dav. The injection of a liquid column located in the pipe 8 overcomes the counter-pressure of this column and enters the storage tank through the vertical body 4. torus 2, B. which is created from: excess pressure a1, equal to pressure C aipar at. c. and subtracted pressure created by the height of the liquid column in the tube 8. Overpressure generated in the tank. Cumul torus 2, begins to force the liquid out of the nozzle 11 and, if the pressure is greater than the pressure created by the height of the liquid column, is located in this nozzle, THAT the steam causes this backpressure and drops to the ba.k- A: Kkumul To.R il and further. On the fitting 13 Sbr: flies into the atmosphere.

Strain1van1Ile: a pair occurs until the pressure in the apiarate does not increase to the desired value; 3. otherwise: neither. The overpressure in the baja ajkumulator 2 also acts on the table. below the pipe 11, the steam output .3 1bak-a1K1iumul; Yator 1 is always carried out by displacing the liquid from the pipe /, /.

With a decrease in pressure in the apparatus to the norm, steam build-up is stopped.

The cross section of the vertical pipe - and 5 is much larger than the cross section of the pipes /./ and 8, which both treats stable work - device,

as the fluid in these pipes is gait. the possible number of steam pressure.

Harsh / release of liquid from patru.bkov 8 1I - / i / is not denied. It works on the operation of the device because it is water from vertical pipes and 5 and the back of the battery / and 2.

The liquid from the apparatus; the system enters through the valve 7 and fills the entire volume of the fitting of the fitting 12. When the device is filled above this level, excess liquid is drained through this fitting, and that is the most adjustable | Routes u.ro.ven fluid in a-ppar at.

The proposed device for adjusting the pressure is: and. And the ukan midkasti has a significantly smaller height (.2 times). And metal1e.cast, it is more convenient in the maintenance service, it allows to reduce the amount of installation work and the terms of the input. in ekkpluatatsiyu and ensure the safe operation of the deae (atmospheric-type rator.
