DETAILED DESCRIPTION OF THE INVENTION

(6) The water-supply device (industrial designationCRAB) contains the vertically oriented hydraulic accumulator 1 with the membrane 16, the inlet and outlet connections 6, 7, accordingly and the filter 13, conjoint to the hydraulic accumulator, with the removable cartridge 18 located in the casing. The hydraulic accumulator 1 is made in the suspended manner and equipped with the multifunctional commutator 5, fixed in its lower part, with the flange in its upper part, for the attachment to the hydraulic accumulator 1. The commutator 5 (its casing part) is made with the channels, connected with the inlet and outlet connections 6, 7, and with the holes 8, 9 for the controlling and regulating equipment attachment, and the casing of the filter 13 is installed on the thread made at the commutator 5, which functionally serves as the cover of the casing of the filter 13.

(7) The casing of the filter 13 is installed vertically (coaxially to the accumulator 1), and the inlet and outlet connections 6, 7 are located horizontally by both sides of the filter 13 and oppositely directed: the connection 6 is to the pump, and the connection 7to the water consumer.

(8) The casing of the filter 13 is fixed on the thread, made at the collector 5, by means of the removable nut 12.

(9) The hydraulic accumulator 1 is made welded, of the metal sheet, in the geometrical shape of a cylinder with the round edges, and equipped with the bracket 2 for hanging to the support (without image) and with the worm drive clamp 2 on the hydraulic accumulator 1.

(10) The device is equipped with the sign 4 of the month of change of the filter 13 cartridge 18, which is fixed on the clamp 3.

(11) The controlling and regulating equipment of the commutator 5 is made in the form of the manometer 11 and the pressure relay 10, connected with the commutator 5 channel with a possibility to be rearranged and connected to any of connections 6, 7 through the holes 8, 9 (unused holes 8, 9 are blinded off):

(12) The collector 5 is equipped with the built-in return valve 17, installed in front of the inlet connection 6 and built-in globe valve 15 with the rotation plug, installed in front of the inlet connection 7.

(13) The filter 13 has the cartridge (filtering element) 18, leaking from the periphery to the central channel, and is equipped with dismountable-mountable plug 14 for the nut 12 rotation during the filter 13 casing assembling on the commutator 5.

(14) So, the basis of the CRAB proposed device is the multifunctional part commutator 5, to which such elements as listed below can be connected without additional transition members: Hydraulic accumulator 1 (the upper part of the commutator 5 is the flange of the hydraulic accumulator; The casing of the cartridge filter 13 (the lower part of the commutator 5 is the cover of the cartridge filter 13, the filter 13 casing is fixed to the commutator 5 by the nut 12); Pressure relay 10; Manometer 11; Inlet connection 6, the built-in return valve 17 is located behind the inlet connection 6; The outlet connection 7, the built-in globe valve 15, which is controlled by the plug, is located in front of the outlet connection.

Preferred Embodiment

(15) The water-supply device is operated as follows.

(16) The device is supplied to the operation area in the assembled condition and requires the fixation on the wall of the bracket 2 with the further fixation of the hydraulic accumulator 1 on the bracket 2 by means of the worm drive clamp 3. The water comes through the connection 6 to the filters, as well as through the cartridge 18 to the hydraulic accumulator 1 and to the connection 7 to the consumer, in case of the opened globe valve 15. The return valve 17 prevents spontaneous water leakage. The rated direction of the water supply is shown with the arrows at the external surface of the commutator 5.

(17) The holes (outlets) 8 and 9, unused for the manometer 11 and the pressure relay 10, shall be blinded with the blind joints. It is also possible to assemble additional automatic elements on free holes 8, 9, in particular, such as the flow, liquid temperature control, etc.

(18) The system is completed with the plug 14 for the nut 12 rotation when changing the filter 13 cartridge. The sign 4 with the month of the filter element 4 changing with help of the worm drive clamp 3 is also fixed on the hydraulic accumulator 1.

(19) The main advantage of the device is that the consumer is provided a possibility to locate compactly the constructively and functionally joint in one item (product) integrated functions of: The return valve 17; Automatic control of the pump by the pressure relay 10 signals; Visual control of current pressure in the system by means of the manometer 11; Water filtering by the filter 13; Regulating of the manifold flow passage by the globe valve 15; Accumulating of a certain water volume; Recording of the month of the filter 13 cartridge changing; Equipping, if necessary, with the additional elements of automatics (shall be connected to the unused holes 8, 9 instead of the blind joints).

(20) The consumer has a possibility to configure the device equipment, control it visually and operate from one place, at one operational fieldcommutator 5. During the volumetric flow and/or pressure rate regulating, the consumer has a possibility to control effectively the result of the regulating and make the gradual regime selection.

(21) As a result, the dimensions have been reduced and the device structure has been simplified at the cost of the number of transferring and connecting parts minimizing, with the simultaneous improvement of the conditions of the control and operation over the water-supply regimes from one working placefrom a commutator 5 that presents constructively and functionally the combined unit of the water-supply device in the whole.
