Abstract
A valve (101) that can be used as a pressure limiter, for example in a sanitary supply line. The valve (101) according to the invention includes a valve housing (1), a fluid line piece (2) being provided in the housing interior thereof, the downstream side circumferential edge area thereof forming a valve seat (3) for a valve body (4), wherein the valve body (4) can be displaced between an open position and a closed position, in which closed position the valve body (4) acts on the downstream circumferential edge area of the fluid line piece (2), by the pressure of the fluid flowing in through the fluid line piece (2) on one side, and a downstream side pressure acting on the valve body (4) opposite to the regular flow-through direction on the other side.

A valve comprising a valve housing (1), having an interior space in which a fluid line piece (2) is provided having an outflow-side circumferential edge region that forms a valve seat (3) for a valve body (4), said valve body (4) can be moved between an open position and a closed position firstly by a pressure, which acts on the valve body (4), of the fluid flowing in through the fluid line piece (2) and secondly by a counterpressure, in said closed position the valve body (4) acts on the outflow-side circumferential edge region of the fluid line piece (2), the counterpressure is adapted to act on the valve body (4) counter to a regular throughflow direction, a sliding guide having a guide path is assigned to the valve body (4) and is bounded by a housing inner circumference of the valve housing (1) and an outer circumference of the fluid line piece (2), the valve body (4) has at least one annular sliding piece (5), which is displaceably guided in the sliding guide, and a closure piece (7) which acts on the valve seat (3) in the closed position, and the closure piece (7) and the sliding piece (5) are connected to one another by connecting webs (6) which delimit throughflow openings therebetween wherein the sliding travel of the valve body (4) is delimited by at least one stop in the valve housing (1), the stop interacts with a counterpart stop on the valve body (4), and at least one of the stop is formed as an annular shoulder (8) provided on the housing inner circumference, or the counterpart stop is arranged on the connecting webs (6).
A valve comprising a valve housing (1) having an interior space in which a fluid line piece (2) is provided having an outflow-side circumferential edge region that forms a valve seat (3) for a valve body (4), said valve body (4) can be moved between an open position and a closed position firstly by a pressure, which acts on the valve body (4), of the fluid flowing in through the fluid line piece (2) and secondly by a counterpressure, in said closed position the valve body (4) acts on the outflow-side circumferential edge region of the fluid line piece (2), the counterpressure is adapted to act on the valve body (4) counter to a regular throughflow direction, a sliding guide having a guide path is assigned to the valve body (4) and is bounded by a housing inner circumference of the valve housing (1) and an outer circumference of the fluid line piece (2), the valve body (4) has at least one annular sliding piece (5), which is displaceably guided in the sliding guide, and a closure piece (7) which acts on the valve seat (3) in the closed position, and the closure piece (7) and the sliding piece (5) are connected to one another by connecting webs (6) which delimit throughflow openings therebetween wherein at least one ring seal (9, 10;
- 11, 12) or slide ring seal is provided at least one of between the housing inner circumference and the valve body (4) or between the valve body (4) and the outer circumference of the fluid line piece (2).
A valve comprising a valve housing (1) having an interior space in which a fluid line piece (2) is provided having an outflow-side circumferential edge region that forms a valve seat (3) for a valve body (4), said valve body (4) can be moved between an open position and a closed position firstly by a pressure, which acts on the valve body (4), of the fluid flowing in through the fluid line piece (2) and secondly by a counterpressure, in said closed position the valve body (4) acts on the outflow-side circumferential edge region of the fluid line piece (2), the counterpressure is adapted to act on the valve body (4) counter to a regular throughflow direction, a sliding guide having a guide path is assigned to the valve body (4) and is bounded by a housing inner circumference of the valve housing (1) and an outer circumference of the fluid line piece (2), the valve body (4) has at least one annular sliding piece (5), which is displaceably guided in the sliding guide, and a closure piece (7) which acts on the valve seat (3) in the closed position, and the closure piece (7) and the sliding piece (5) are connected to one another by connecting webs (6) which delimit throughflow openings therebetween wherein two ring seals (9, 10;
- 11, 12) or slide ring seals, which are spaced apart from one another, are provided at least one of on the sliding piece (5) or on the outer circumference of the fluid line piece (2), between said ring seals or slide ring seals there is provided at least one annular groove (13, 14) formed as a grease chamber.
A valve comprising a valve housing (1), having an interior space in which a fluid line piece (2) is provided having an outflow-side circumferential edge region that forms a valve seat (3) for a valve body (4), said valve body (4) can be moved between an open position and a closed position firstly by a pressure, which acts on the valve body (4), of the fluid flowing in through the fluid line piece (2) and secondly by a counterpressure, in said closed position the valve body (4) acts on the outflow-side circumferential edge region of the fluid line piece (2), the counterpressure is adapted to act on the valve body (4) counter to a regular throughflow direction, a sliding guide having a guide path is assigned to the valve body (4) and is bounded by a housing inner circumference of the valve housing (1) and an outer circumference of the fluid line piece (2), the valve body (4) has at least one annular sliding piece (5), which is displaceably guided in the sliding guide, and a closure piece (7) which acts on the valve seat (3) in the closed position, and the closure piece (7) and the sliding piece (5) are connected to one another by connecting webs (6) which delimit throughflow openings therebetween wherein the valve housing (1), in an inflow-side partial region of the sliding guide, is open to the environment.
