SU45780A1 - Automatic shut-off valve for hydroaccumulator - Google Patents

Description

   The proposed valve accumulator valve device, which is controlled automatically by a known method using a float sliding along a valve-connected shank, is designed for smooth and unaccented discharge of water from the reservoir of the accumulator into the separating-discharge line and for filling the reservoir from it the right moments. For this purpose, the device uses three valves of different sizes, made and interconnected in such a way that the water inlet from the pipeline to the reservoir required at known water levels in it, and the outlet from it are properly provided.

In FIG. 1 depicts the proposed valve device in a vertical along the axis of the section, and FIG. 2,3 and 4 diagrams of its position at different levels of water in the tank.

The body of the valve device itself consists of six parts (Fig. 1), of which the three upper parts — a separate dome-shaped valve 7 and the nozzle 9, which are cracked together with the through holes on the sides and the patrol / 5 — are placed inside the reservoir ia of its bottom J8, and the lower parts of the body i with two valves 27 and -30 in it, its lid 4 / and angular bend 45 when: repleni bottom of the tank outside it.

265) 1

The housing 22 is connected by a knee 44 (FIGS. 2, 3, and 4) to a pressure pipe that is connected to the corner elbow 45 via a non-return valve 46. A shaft 8, rigidly connected to the valve 7, passes freely along the axis of the device housing. and fastened with the rod 2 located inside the tank, along which the float slides with changing water level. There are two stop rings on the rod. and the first is above the float, and the second is below it. The valve 7, having a seating seat fO in the nozzle 9, with its flange 6 can rest on the short shoulders of three radially placed levers 57 with weights 5 K & other shoulders. Inside the housing 22 there is a cylindrical wall in the form of a cup 5 /, in which the valve 27 moves at the top, having a seat 26 at the top, and an inside-through passage 33 closed by the poppet valve 30 of a smaller diameter against the valve 27. Both valves are loosely mounted on the rod S independently of each other, but their movement downwards is limited by a stop ring 35 fixed on the rod. The rod 5 ends at the bottom with a piston 49 moving in the cylinder 5 / fixed in the vertical part of the knee 45, which has small calibrated holes at the top and bottom. ..

Such a device serves as a damper for smooth movement of the "unstressed valve opening rod".

The operation of the device is explained in the schema mami (Figs. 2, 3 and 4), depicting its three basic positions:

I. At the upper limit of the water level in the tank (Fig. 2) the float /,: catching the upper stop ring. rod 2, holds it and the rod 8, and “with them domed and valve 7. and seized by the stop ring 35 zlapana 27 and 30, in the upper limit position, so that valve 30 opens the rotary hole 33 in the main body.” and the latter is pressed against the top of its saddle 26, and thus stops {further inflow of water from the reservoir through knee 44 from the magistral. The discharge of water from the reservoir of the petrol tank will initially occur through from: 30 valves covered with valves 30 in the valve 27 and further through the angular elbow # 5 and non-return valve 46. Water consumption will decrease the level in the tank , the shopfighter is lowered and non-retarded. They are more than rod 8, valves 7 and Sv and this damper 49 are lowered and take the position shown in fig. 2 the dotted line at which the valve 1Y, earlier referring to valve 27, closes the communication with the line through the knee. Then, with excessive pressure of water and air in the hydroaccumulator, the valve 27 is detached from the saddle 26 and calmly, thanks to the action of the damper P, 57, falls down into the cup 5 /, opening the free passage of water from the multiplexer to the main through the knee 44.

I. At medium levels of water (Fig. 3)

dome valve 7, lowered under its own weight, sits down without closing the side openings

in the nozzle 9, on the short shoulders of the arms 57, not turning them, but the valve 27,

looking up from his saddle at the beginning

water flow from the line is

entirely in a cup 5 / case 22. When

This position of the valves -7 and 27 stop th o ring 55 of the rod 8 will not come yet

into the reservoir of the battery through the collet 44, the housing 22, the pipe 75 and through the hole in the nozzle 9 and in the same way pass back from the tank to the line, but the water will flow back partially and another way: through the through hole .5 in the valve body 27 and further through the knee 45 and check valve 46.

Iii. At the lower limit of the water level in the tank (Fig. 4) the float / sits on the lower thrust ring 5 of the rod 2 and, separated from the water, with its weight overcomes the resistance of the loads 58 on the levers 57, which kept the dome-shaped valve 7 in the middle position. This valve is lowered onto the rubber seat W, and the damper 49, 57 ensures a relaxed fit of the valve and, thus closing the side openings in the nozzle 9, separates the battery from the main line. The valve 27 remains in the same position as with the average water level, because the rod 8 passes freely through the valve body, acquiring contact with it by the stop ring 55 only when the valve is raised.

When the tank is filled, the valve 7 rises under the appropriate pressure of the water coming from the main line.

The correct action of the proposed device will occur, as can be seen from the foregoing, only with a strict calculation of the size and weight of its moving parts: float, rod, all valves and balancing levers with weights.

The subject matter of the invention.
