Abstract

The invention relates to sanitary engineering and is intended for use, for example, in garden areas. The aim of the invention is to improve ease of operation. The installation includes a housing, a spray nozzle, a valve that controls the temperature of the outgoing water, a check valve installed at the entrance to the housing, a drain valve and a heating element. A piston with a membrane is installed in the housing, on which a slider having a through hole, a stop sleeve with a window and a partition wall are rigidly fixed. A channel is made in the housing that connects the supply line with the sub-membrane cavity formed by a septum, a spray nozzle and a piston membrane. The overmembrane cavity is formed by a slide membrane, body walls and a valve and is connected to the spray nozzle cavity by a slide hole. 1 il.

Description

The invention relates to sanitary engineering, is intended for use in garden plots, and is additional to the author. St. Ns 4705579.

The purpose of the invention is to improve ease of operation by maintaining the set temperature of the outgoing water when the pressure in the supply line changes.

The drawing shows the shower head, a longitudinal section.

The installation includes a housing 1, a spray nozzle 2, a valve 3 regulating the temperature of the outgoing water, a check valve 4 installed at the entrance to the housing 1 in which the drain valve 5 and the heating element 6 are mounted. In the housing 1 there is a piston 7 with a membrane 8, on which the slider 9 is rigidly fixed, having a through hole 10, a stop sleeve 11 with windows 12 and a partition 13.

The housing 1 has a channel 14 connecting the supply line 15 with a sub-membrane cavity 16, which is formed by a partition 13, a spray nozzle 2 and a piston membrane 8 8. The submembrane cavity 17 is formed by a membrane 8 of the slide 9, housing 1 and valve 3 and is connected the through hole 10 of the slide 9 with the cavity 18 of the spray nozzle 2.

The spray head is equipped with a heating element 6,

The water from the supply line 15 flows through the check valve 4 into the housing 1 with the drain valve 5 open. After the appearance of water from the drain valve 5, the latter is closed manually (the housing is filled with water). By means of the heating element b, water is heated in the housing 1. The valve 3, which controls the temperature of the outgoing water, is set to a response pressure greater than the pressure in the supply line 15. When the water in the housing 1 is heated, i.e. . in a closed volume bounded by a check valve 4, a drain valve 5, a regulating valve 3, its pressure increases, valve 3 opens and heated water under pressure enters the permembrane cavity 17, then through the opening 10 in the slider 8 into the cavity 18 of the spray nozzle 2 and sprayed. A new portion of the water enters the emptied housing 1 from the supply line 15 through the check valve 4 and the cycle repeats.

The temperature of the outgoing water depends, other things being equal, on the heating time determined by the setting of the control valve 4.

Adjusting the spray head to the desired temperature is carried out by axial movement of the spray nozzle 2 relative to the housing 1. Moving the spray nozzle 2 causes

moving the piston 7 with the membrane 8 fixed on it, the latter changing the setting of the adjustable valve 3.

The change in water pressure in the supply

line 15, after adjusting the spray head to the required temperature in the manner described above, channel 14 is transmitted to the submembrane cavity 16 and acts on the membrane 8, and the last

changes the setting of the control valve 3 depending on the pressure change in the supply line 15. Thus, the temperature of the outgoing water is maintained constant.
