Safety device arrangement of water heating system

摘要

The safety device arrangement of a water heating system, in particular of solid fuel-burning heating systems, comprises a temperature-dependent actuator (3) that is disposed in a hot water circuit so that an extensible shaft (4) thereof bears against a sliding closing member (2) mounted within a distribution device body (1) to thereby enabling in its functional position simultaneous interconnection of hot water circuit with discharge and opening of cold water supply into the system. The distribution device body (1) is fastened within hot water discharge pipe in such a manner that the shaft (4) of the temperature-dependent actuator (3) thereof bears against pressure of a spring (8) against said sliding closing member (2) of a slide valve, the body of which is connected to both the discharge and the heater cold water supply pipe. Said temperature-dependent actuator (3), the temperature sensor of which is freely accommodated in a cavity (10) of an end portion being provided with external thread for connection to the hot water heater circuit, is fastened in the distribution device body (1) through the mediation of an intermediate ring (5) having holes for passage of hot water into the slide valve space, wherein said distribution device body (1) is further provided with a coupling sleeve (14) for connecting to the discharge and coupling sleeves (15) for supply of cold water into the heater, whereby said extensible shaft (4) of the temperature-dependent actuator (3) bears against said sliding closing member (2) of the slide valve counter pressure of the spring (8), arranged within a housing (9), screwed in the distribution device body (1) second end portion. It is described an arrangement of a water heating system safety device, particularly for solid-fuel-burning heating systems comprising a temperature-dependent actuator (3), that is disposed within a hot water circuit so that an extensible shaft (4) thereof bears against a sliding closing member (2) mounted within a distribution device body (1) to thereby enabling in its functional position passage of cold water through a heat-exchange apparatus located at the system hot water discharge or directly in the heating system. The distribution device body (1) is fastened within or behind the hot water heater discharge so that said distribution device sliding closing member (2) forced against seat of the distribution device body (1) against pressure of a spring (8), interconnects in extended functional position of said extensible shaft (4) of the temperature-dependent actuator (3) a pressurized cold water source via a heat-exchange apparatus being disposed at the hot water outlet, with a discharge.
