SU36922A1 - A device for the release of sewage water in an open pond (sea, lake, etc.) - Google Patents

Description

Devices are known for discharging sewage into an open reservoir (sea, lake, etc.), which also serve to prevent the backwater in the sewer system due to an increase in the level of the reservoir and the action of waves. These devices represent the failure of a valve installed in the outlet of the manifold and opening towards the reservoir.

The invention aims to improve valve performance and consists in the fact that the valve in the shape of a ball is suspended at the center or cable in front of the manifold outlet so that, under the influence of hydrostatic pressure and the action of waves from the reservoir, the valve is pressed against the saddle of the hole; in the absence of pressure from the reservoir side, the valve freely passes sewage water.

In FIG. 1 shows a diagram of the outlet of the collector, indicating the levels of the reservoir and the nature of the wave; FIG. 2-side view of the valve, FIG. 3-view of it from the pond; FIG. 4 plan, and FIG. 5-horizontal (left) and vertical (right) valve incisions.

Discharge of sewage in general and, in particular, stormwater from the territory

(60s)

cities in the sea are complicated by the fact that during the time of wind from the sea, a rise in its horizon along the city coast is formed. This increase in the level can reach several meters, and if special devices are not foreseen, the sea water may go inside the coastal area and partially flood the mountain. At the same time, rain showers will naturally be backed up, the carrying capacity of which will be significantly reduced, and the discharge of storm water from the lowest areas of the city will be completely impossible. Meanwhile, the most intense showers usually coincide in time with sea storms. Consequently, the discharge of stormwater into the sea should occur just when it is very difficult as well. in some part, without special devices, it is completely impossible.

To prevent such backwaters, valves installed at the outlet of the collector are intended.

In theory, the valves should open when the lowest points of the wave approach the coast, which are located significantly below the average storm sea level and even slightly below the normal average level of the sea.

When the gerbei waves are flowing, the valve should close to prevent seawater from entering the shower. Opening and closing of the valve occurs automatically under the action of a pressure difference on both sides of it, which is always directed towards the lower water level. .

If the amplitude of the wave oscillations of the sea surface is of too great a significant time, the valve will not open and close too often. In order to avoid non-uniformity of flow in the shower itself when the valve is operating, it is advisable to install several mouth holes at each manifold located at different points in the direction of the waves. In this case, the valves will open in turn, and in the collector itself there will be approximately a steady-state mode.

The drawing (Fig. 1) shows the wellhead scheme. Collect a collector or a shower, and the nature of the normal and storm surface of the sea. The mouth of the collector 5 is located directly on; d normal sea level. At the same time, the average high ground level of the sea level 4 and the nature of the storm waves 6 are noted. At such waves, the sea level sometimes even lies below the normal average level.

The design of the valve itself should as far as possible satisfy the following requirements; 1) the valve should open and close very quickly and with: Minor spread the pressure on both sides of it; 2) the opening and closing should be automatic, 3) the valve mechanism should be simple and reliable in operation, 4) when fully opened, the valve should not resist water flowing out of the manifold, b) when fully closed, the valve should be sufficiently tightly pressed to the hole so as not to let the seawater flow to the collector, 6) the valve should be as cheap as possible.

The proposed device is intended to satisfy the above requirements and consists of the following. Before . the outlet of the pipe is suspended on a chain or cable 2, a wooden ball valve 1 on a horse bean 9. In view of the large length of chain 2, deviating the ball from its equilibrium position to the sides requires only a small force, less than a statistical water pressure, it is found in the pipe, or the dynamic pressure is flowing; The ball valve itself should be sufficient so that the waves cannot throw it up, which can be achieved by filling the ball with concrete, stones, metal scrap, etc.

To prevent the ball from tilting too far from the hole when opening, it is tied with chain 7 with a spring link to a stand embedded in the pipe (Fig. 2) and two chains 8 to the front plane of the tip of the pipe.

The edge of the hole is trimmed with wood frame 10, and the ball itself is also made of wood, to soften shocks during closing. The shape of the valve is chosen as a ball in order to eliminate the effect of a skewed valve on the closing density. This eliminates the need for any friction-causing rails that delay the opening and closing of the valve.

An exemplary valve design is shown in FIG. five.
