Abstract

FIELD: water supply and irrigation systems. SUBSTANCE: ram body is a combination of pipes 1 and 2 equal in their cross-section. Angle-piece 3 joins the pipes together. In the angle-piece there is a pressure valve. The valve has rigid perforated disk 4 and flexible disk 5. Pipe 1 has port 6. A collision valve regularly covers the port. The valve has rigid cylindrical stem 7 and two flexible gaskets 8 and 9. A differential of water levels is created in the source of water, and the left part of body 1 is connected to the upper reach. Pressure pipe 12 is connected to the consumer. Water enters body 1 and pipe 12, and it is drained in the atmosphere through open port 6. At a certain flow speed port 6 is abruptly closed by the ram valve to create a hydraulic shock. The shock wave makes water enter pipe 12. The pressure valve is closed, the ram valve is opened, and the cycle is repeated. EFFECT: higher efficiency. 2 dwg

Description

 The invention relates to water-lifting installations and can be applied to water supply systems and for irrigation purposes.

 Known hydraulic rams, comprising a housing, shock, discharge valves and an air accumulator for smoothing pressure peaks inside the housing.

 A disadvantage of the known designs is the complexity of the design and manufacture.

 The aim of the invention is to simplify the design and increase reliability.

 This goal is achieved by the fact that the body of the ram is made of two pipes of the same cross section, interconnected via a square. One tubular part of the casing is installed horizontally in the working position, and the other part is vertically positioned. In the square, a discharge valve is fixed, made in the form of a perforated disk and an elastic disk, interconnected in the center. The shock valve of the ram includes a rigid cylindrical rod and two elastic gaskets, which during operation open a window made directly in the housing. The width of the upper valve gasket is larger than the window, and the lower one is smaller, which ensures the tightness of the window closure for any curvature of the body wall. The rod with elastic gaskets is oriented along the axis of the housing and provided with two guides. The vertical movement of the shock valve is limited by stops fixed to the guides. Hydro-ram consists of a body, shock and pressure valves and a discharge pipe.

 In FIG. 1 depicts the proposed hydrated ram, General view; in FIG. 2, section AA in FIG. 1. The body of the ram is made of pipes 1 and 2 of the same cross section, interconnected by an elbow 3. In the elbow 3, a discharge valve is installed, including a rigid perforated disk 4 and an elastic disk 5, interconnected in the center. For water to enter the atmosphere in the pipe 1 there is a window 6, which is periodically blocked by a shock valve. The shock valve consists of a rigid cylindrical rod 7 and two elastic gaskets 8 and 9 having different widths. The rod 7 with gaskets 8 and 9 is oriented along the axis of the pipe body 1. The upper gasket 9 is wider than the window 6 in width and the lower 8 is less than that ensures the tightness of the window closure for any curvature of the body wall. The vertical movement of the shock valve along the guides 10 is limited by the stops 11.

 The hydraulic ram hydraulic accumulator is made in the vertical part of the housing 2 by installing a pressure tube 12 coaxially (coaxially) in it.

 Gidrotaran works as follows.

 In the water source (spring, stream, small channel, etc.), a difference in water levels is created with a height of at least 0.6 m by installing a retaining or overflow wall. Using the booster pipe 1, the left side of the ram body is connected to the upper pool, and the pressure pipe 12 to the consumer.

 Water enters the ram pipe, fills the housing and pressure pipe 12 to a height equal to the inlet pressure. In the space between the vertical part of the pipe 2 and the pressure pipe 12, air remains, which is compressed by the output pressure of the water. In this case, the shock valve is in the open state (in the lower position). The discharge valve is also open. Through the open window 6 of the shock valve, water is poured into the atmosphere. Upon reaching a certain flow rate of water in the ram pipe 1, the window 6 is abruptly closed by a valve, thereby creating a water hammer. Elastic gaskets 8 and 9, pressed by a cylindrical rod 7 to the wall of the tubular body 1, provide a tight seal. The shock wave, propagating through the body, squeezes the elastic disk 5 of the discharge valve and water enters the pipe 2 and then into the discharge pipe 12. The water level in the discharge pipe rises and becomes higher than the inlet.

 After the shock wave attenuation, the elastic disk 5 of the discharge valve is pressed against the perforated disk 4 and prevents the outflow of water from the discharge tube 12.

 The shock valve (rod 7 with gaskets 8 and 9), under the action of its own mass, goes down and opens a window 6 for water to enter the atmosphere, after which the cycle repeats.
