SU1588330A1 - Pulse action water outlet - Google Patents

Abstract

The invention relates to the field of irrigation mechanization and can be used to cyclically supply nutrient solution or water in greenhouses. The aim of the invention is to improve the performance of the outlet. The pulsed water outlet contains a pneumohydroaccumulator 1, an elastic valve in the form of a rubber tube 2 and a quenching chamber 3. After the pneumohydroaccumulator 1 is filled with water under pressure, water pushes out the tube 2 from the neck of the pneumohydroaccumulator 1. The tube 2 presses the nipple 6, forming a gap, and a full hole. the passage of water into the chamber quenching 3. 1 Il.

Description

The invention relates to the mechanization of irrigation and can be used mainly for cyclical supply of nutrient solution or water to plants in greenhouses, and can also be used for irrigation of orchards and vineyards.

The purpose of the invention is the improvement of operating parameters by ensuring the constancy of the area of the bore at the outlet of the pneumatic accumulator. 1

The drawing shows a diagram of the outlet pulsed action.

The pulsed water outlet consists of a pneumatic accumulator 1, elastic, made in the form of a stepped rubber tube 2 bypass valve, the body of the quenching chamber 3, made with inlet 4 and outlet 5 fittings, a nipple 6, on which a rubber tube 2 is put on, the lower part of which is inserted between the shoulder 7 and the lower part 2 of the nipple 6. In this case, the upper part of the rubber tube 2 forms an interference fit with the nipple, the magnitude of which is greater than the gap between the tube and the neck of the pneumatic accumulator. 2

The outlet works as follows.

In the initial state, the internal cavity of the pneumatic accumulator 1 through the gap between its neck and tube 2 is in communication with the atmosphere. ''

At the beginning of the filling period, under the influence of water pressure from the supply pipe through the inlet 4, the rubber tube 2 is pressed against the shoulder 7 and the neck of the pneumatic accumulator 1 with the lower and middle parts, thereby excluding the connection of the pneumatic accumulator with the atmosphere. With a further increase in pressure, the nose of the tube moves away from the nipple 6 and the pneumohydroaccumulator is filled with water.

about

During the splash period, when the pressure in the network decreases, the tube returns to its original position when the nose of the latter is pressed against the nipple, and the lower and middle parts move away from the neck 0 of the pneumatic accumulator, while ensuring a connection with the atmosphere and a constant flow section at the outlet of the neck of the pneumatic accumulator. Water, under the action of pressure, is uniformly supplied to the plants through the discharge nozzles 5.

Claims (1)

Claim A pulsed water outlet including a hydropneumatic accumulator with a quenching chamber, which has a bypass valve connected to the pressure network and made in the form of a nipple with a rubber tube passing through the mouth into the hydropneumatic accumulator and installed in its upper part with an interference fit, ₅ characterized in that, with In order to improve the operating parameters by ensuring the constancy of the passage area at the outlet of the pneumatic accumulator, the quenching chamber is equipped with an outer annular collar covering the rubber the J0 tube of the nipple, made in the form of a central rod passing along the length of the tube inside the pneumatic accumulator, while the rubber tube is stepwise expanding to the inlet and is installed with a gap relative to the neck of the hydropneumatic accumulator, the gap being less than the interference of the rubber tube on the nipple.
