Description

(54) DEVICE FOR CONNECTING PROMOTIONAL PLANTS TO THE CLOSED IRRIGENTAL NETWORK

I

The invention relates to agriculture, in particular to irrigation machinery, and can be applied to connect sprinklers to a closed irrigation network.

Hydrants are known for connecting sprinklers including a locking device with a suction inlet-connection column C13.

In a known hydrant, the feed is fed through a cylindrical plug with grooves-conduits.

Its drawbacks are considerable metal intensity, fragility of sealing machines due to their rubbing against the cylindrical surface of the body at the moments of removing and fitting the sub-column to the hydrant, as well as large hydraulic losses associated with the passage of water through water outlets.

Closest to the invention are cylindrical hydrants.

screw locking device to connect the sprinkling machines to the closed irrigation networks C2b

The hydrants are a body with a cylindrical screw gate and tides for placing the connecting column on the hydrant.

Claims (1)

The sprinkler connection column of the sprinkler is put on the body of the hydrant and secured to it with special hooks. The centering of the connected column on the hydrant and consolidation of the connection of the hydrant-supplementary column is carried out by a petal rubber cuff, which is lightly put on the cylindrical part of the hydrant body and seals the connection under the pressure of water passing through the column when the hydrant is opened. These hydrants also have a large metal content, time-consuming to manufacture. Their disadvantage is also the fragility of the sealing cuff, emanating from the wear of the petal part of the friction against the cylindrical surface of the body and mechanical damage caused by the cuff centering of the connecting column on the hydrant at the moments of removal and fitting of the column to the hydrant. The purpose of the invention is to reduce the metal capacity and increase reliability of operation. This goal is achieved by the fact that the hydrant is made in the form of a flange, having an end groove, and the cuff holder is fixed on the connecting column and is made with a corresponding groove with an annular protrusion, while the cuff is installed in the cuff holder the possibility of its interaction with the end surface of the flange. FIG. Given the device, a general view; in fig. 2 — node I in FIG. 1. The device consists of a hydrant, made in the form of a flange 1, mounted on the drive posts 2 of a closed irrigation network and having a screw locking mechanism 3 with a lid 4. The upper plane of the flange is made with a protrusion 5 and an end surface 6 which has a groove 7. The connecting column 8 with the cuff holder 9 is mounted on the flange 1 and is centered on it by the ring 10. The cuff holder is fixed to the cuff 11, which has an end sealing lip 12. The cuff holder has a movable ring 13 with handles 14 and hooks I5 for fixing the connecting column to the flange 1. The device works as follows. ,. The connecting unit 8 of the rain assembly is laid on the flange 1, centered with the ring 10 of the carrier 9 and the groove 7 of the hydrant. The fixing of the connecting column 8 on the hydrant is provided by the hooks 15 of the swivel ring 13 onto the tidal waves of the hydrant. The lid 4 abuts the protrusion 5 of the hydrant. The hydrant is closed. When the cover of the hydrant 4 is opened with a screw locking mechanism 3 by the pressure of water entering the connecting column, the end sealing lip 12 of the cuff 11 presses against the end surface 6 of the hydrant and seals the connection of the column with the hydrant. Thus, the horizontal surface is working for the sealing cuff. The use of the device reduces the metal content of hydrants, eliminates the failure of sealing cuffs, reduces the energy intensity of closed irrigation systems by increasing the flow area of hydrants and reducing hydraulic losses. The invention The device for connecting the sprinklers to a closed irrigation network, including a hydrant with a locking mechanism, a connecting column and a cuff holder with a sealing lobe lip, characterized in that, in order to reduce metal intensity and increase reliability, the hydrant is designed as a flange having an end groove, and the manhattaderzhatel is fixed on the subconnecting column and is made with a corresponding groove in an annular protrusion, the npji of this cuff is installed in the cuff holder e chance reacting it with the end surface of the flange.
