Description

I

The invention relates to agriculture, in particular, to drip irrigation techniques.

A known dropper consisting of a nozzle and an elastic membrane located under it, the deformations of which with pressure fluctuations contribute to leveling the flow rate 1.

A disadvantage of the known dropper is the unreliability of controlling the flow and the complexity and unreliability of attaching it to the pipeline.

A dropper is also known, comprising a housing with a regulating element 2 installed therein.

A disadvantage of the known dropper is also the unreliability of flow stabilization.

The purpose of the invention is to raise it. reliability of flow stabilization.

To achieve the goal, the regulating element is designed in the form of rigid partitions fixed at one end to the body wall;

opposite wall, and a flexible comb, whose teeth are measured between rigid partitions and also do not reach the wall of the housing.

In Fig.1 schematically shows the proposed dropper; Fig.2 section aa in Fig.1.

The dropper consists of a body 1 and a regulating element 2 with rigid partitions 3 with a flexible shaft 10, creating hydraulic resistance to it. The plates 5 of the comb 4 are bent under the action of pressure and change the overlapped passage 6 by an amount necessary for a corresponding change in the hydraulic resistance. The simultaneous operation of all gshastin 5 at the extreme curved position of them is ensured by the fact that there is a non-overlap passage 7 between them and the bridging 3.

Dropper works as follows. Water passes between the flexible plates 5 and rigid partitions 3. The plate L, which bends under the pressure of water, covers the passage 6 between its end and the ledge of the partition 3. The greater the pressure, the more blocked the passages 6. The initial value of the blocked passages provides the specified water flow at normal value of working pressure. At the maximum working pressure, the controlled passage completely closes and the water flows through the non-overlapping passage 7. When the pressure fluctuates between the minimum and maximum values, the flow rate will practically be constant. The number of pairs of partitions 3 with plates 5. Combs C is selected according to the characteristics of the outlets according to the flow rate and the magnitude of the working pressure. The lower the flow rate and the higher the pressure, the greater the number of these throttling elements. Due to the presence of non-overlapping passageways 7, simultaneous operation of all flexible plates 5 is ensured; in this case, 9 cannot act like ordinary valves. The proposed dropper will ensure reliable flow stabilization and is simple in design. DETAILED DESCRIPTION OF THE INVENTION A dropper comprising a housing mounted in a humidifier opening and a regulating element mounted therein, which is characterized in that, in order to increase the reliability of flow stabilization, the regulating element is designed as rigid partitions fixed at one end to the housing wall that do not reach the opposite wall, and a flexible comb, whose teeth are placed between rigid partitions and also do not reach the wall of the housing.
