Claims

1. The water supply device containing a base, a ring of elastic material and a flange, tightened by connecting elements, for the installation on a casing pipe, a hydraulic accumulator with a housing and a working chamber with a connecting fitting mounted on its inlet, as well as a distribution manifold made with two oppositely located connecting parts, with an end-to-end internal channel and an outlet internal channel, while the latter is made with the possibility of connection to the major pipeline of the consumer on the one side, and is connected on the other side with the aforementioned end-to-end internal channel that is connected via a connecting fitting with the working chamber of the hydraulic accumulator, while the manifold is provided with means for draining water from the device. One connecting part is used to rigidly fix the manifold to the housing of the hydraulic accumulator, while the other connecting part is used to rigidly fix it to the base. The manifold is provided with a compression fitting for connecting the end-to-end internal channel with a pressure pipe of the submersible pump.

2. The water supply device according to p. 1 , characterized in that the clamping flange is designed to be installed around the casing pipe, while the base - at the end of the casing pipe.

3. The water supply device according to any of p. 1, 2, characterized in that the water draining means is made in the form of a drain plug installed with the possibility of draining through internal channels from the working chamber of the hydraulic accumulator and from the consumer major pipeline into the well.

4. The water supply device according to any of p. 1, 2, characterized in that the manifold is fixed with one connecting part made in the form of an annular belt in a cylindrical bore made on the base.

4. The water supply device according to any of p. 1, 2, characterized in that the manifold is fixed by another connecting part made in the form of an annular recess to the flange on the hydraulic accumulator housing.

5. The water supply device according to any of p. 1,2, characterized in that the manifold is formed with a threaded part of a compression fitting including a collet, a clamping ring, a sealing ring and a nut to be screwed onto the threaded part of the fitting and compression of the collet with the clamping ring and sealing ring.

6. The water supply device according to p. 1, characterized in that it is provided with a pressure relay fixed to the manifold, connected to the outlet internal channel and made with the ability to generate signals to turn on and off the submersible pump when the pressure in the consumer's major pipeline decreases and increases, respectively.

7. The water supply device according to any of p. 1, 2, characterized in that it is equipped with a pressure gauge mounted on the manifold for visual pressure monitoring.

8. The water supply device according to any of p. 1, 2, characterized in that the manifold is made with a pad eye for fastening the safety hook of a cable from the casing pipe.
