摘要：The invention relates to a gas control valve and a safety valve for burners of amodular gas heating device, which are used to adapt a changeable heat load and for theabrupt disconnection of the flow of combustible gas, in particular for heating living spaceand for the supply of warm water. According to the invention, the gas control valve andthe safety valve for burners of a modular gas heating device, comprising at least twoclosing elements which are arranged in an axial manner at a distance from each other, arepositioned in a coaxial manner in relation to each other in a housing (1) between an inletchannel (2) and an outlet channel (3), and close the gas control valve and the safety valvein an abrupt manner independently from each other, by means of an associated springelement (5, 9), when in an idle state. According to the conception of the invention, a flowchamber (2.1) and an annular gap extending at least partially in a concentric manneraround the flow chamber (2.1) are arranged between the inlet channel (2) and the outletchannel (3). The annular gap (3.1) and the flow chamber (2.1) can be used in an alternatingmanner for the admission and discharge of the gas into and out of the throttle area (10).The two closing elements are displaced in an axial manner in the same direction or in acounter direction in order to achieve an open position thereof and a closed positionthereof, according to the design options.
