RU2042892C1 - High-pressure through-flow water heater - Google Patents

Abstract

FIELD: electrical plants. SUBSTANCE: high-pressure through-flow water heater has pipe 1 with valve 3 on its outlet end accommodating electric water-heating element 2. Actuating mechanism is mounted on pipe and has cylinder 4 with piston 5 whose rod 6 actuates limit switch 7 whenever necessary. Strip 8 mounting limit switch 7 provides for displacement of the latter over it to facilitate heating control. EFFECT: facilitated heating control, improved design. 1 dwg

Description

 The invention relates to electrical installations of residential buildings.

Known flow electric high-pressure heater containing a pipe with a valve at its output end, in the cavity of which there is an electric heating element [1]
In this instantaneous high-pressure electric heater, there are no devices for switching off the electric heating element at the moment of stopping the water intake and until the moment when heated water flows from the nozzle, it is necessary to drain some cold.

Known flow high-pressure electric water heater containing a pipe with a valve at its output end, an electric heating element located in the cavity of the pipe, as well as an actuator fastened to the pipe, interacting with a limit switch [2]
A disadvantage of the known device is the inability to control the temperature of the heating water.

 The aim of the invention is the provision of temperature control of water heating. For this, the high-pressure electric heater contains a bar on which the indicated switch is mounted with the possibility of movement.

 To achieve this goal, an actuator consisting of a cylinder is welded to the nozzle, in the cavity of which the piston freely moves with the rod acting on the limit switch, opening the power supply circuit of the electric heating element.

 The drawing shows a flowing electric high-pressure heater at the time of termination of water intake.

 The flowing high-pressure electric water heater contains a pipe 1, in the cavity of which there is an electric heating element 2 with a valve 3 at its output end and an actuator attached to it, consisting of a cylinder 4, in the cavity of which the piston 5 freely moves with the rod 6 acting on the end switch 7, the moment of operation of which is regulated by moving it on the bar 8.

 The device operates as follows.

 When the valve 3 is open, the water flowing around the electric heating element 2 located in the pipe 1 is heated, since the actuator rod 6 does not act on the limit switch 7 and the power circuit of the electric heating element 2 is not open by the limit switch 7.

 When closing valve 3 and the operation of the electric heating element 2, the pressure in the pipe 1 increases due to an increase in the volume of water and pressure in the line, which in turn causes the piston 5 to rise in the cylinder 4 and the action of the rod 6 on the limit switch 7, which opens the power circuit of the electric heating element 2.

 By moving the limit switch 7 along the bar 8 and covering the valve 3, it is possible to control the temperature of the water heating by the heater.
