The present invention relates to a safety valve (1) having a valve housing (2), in the housing interior of which there is provided a shut-off body (3) which is held in an open position of the safety valve (1) by at least one elastic retention element (4) counter to the force of a medium flowing through the valve housing (2), in which open position the medium flows through a valve opening (5) in the shut-off body (3). Here, the shut-off body (3) is displaceable in the valve housing (2) such that the shut-off body (3), in the event of a pressure drop on its outflow side, moves against a closing body (7) into a closed position of the safety valve (1) in which the closing body (7), which is acted on by at least one resilient pressing element (8), sealingly closes off the valve opening (5) in the shut-off body (3), wherein at least one bypass duct is provided which, in the closed position of the safety valve (1), can be opened to connect the inflow side of the shut-off body (3) to the outflow side thereof until the shut-off body (3), when the pressure has been equalized by the at least one bypass duct, is moved into the open position of the safety valve (1).
A safety valve (1) comprising a valve housing (2) having a housing interior in which a shut-off body (3) is provided, said shut-off body (3) is held by at least one retaining element (4) against a force of a fluid traversing through the valve housing (2) in an open position of the safety valve (1) in which the fluid traverses a valve opening (5) in the shut-off body (3) and said shut-off body (3) is displaceable in the valve housing (2) in such a manner that, in case of a pressure drop on an outflow side, said shut-off body (3) is moved against a closing body (7) into a closed position of the safety valve (1) in which the closing body (7), which is acted upon by at least one pressing element (8), closes the valve opening (5) in the shut-off body (3), at least one bypass duct which, in the closed position of the safety valve (1), is openable such that the at least one bypass duct connects an inflow side of the shut-off body (3) with the outflow side thereof until the shut-off body (3), when the pressure has been equalized by the at least one bypass duct, is moved into the open position of the safety valve (1), the at least one pressing element (8) is guided displaceably by a subregion of said at least one pressing element that faces away from the shut-off body (3) located in a guide sleeve (16) arranged in the housing interior of the valve housing (2).
