Abstract
A sealing diaphragm for a fluid valve is provided. The fluid valve includes a valve housing and a drive unit, the sealing diaphragm being of hat-like design and being configured for enclosing, on the free-end side, a portion of a valve-closing body which projects into the valve housing of the fluid valve. The sealing diaphragm can include a base portion which is configured to be rotationally asymmetrical on the outer circumferential side, the base portion being provided to abut in a form-fitted manner against an opening of the valve housing, and the base portion of the sealing diaphragm being configured to be received between the valve housing and the drive unit in such a way that the opening of the valve housing is sealed in a fluid-tight manner towards the drive unit.
Claims14
A sealing diaphragm for a fluid valve, the sealing valve comprising:
- a valve housing;
- and
- a drive unit having a valve housing carrier configured to couple to the valve housing,
- wherein the sealing diaphragm has a hat-like design and is configured to enclose, on the free-end side, a portion of a valve closing body which projects into the valve housing of the fluid valve,
- wherein the sealing diaphragm has a base portion which is formed in a rotationally asymmetrical fashion on the outer circumferential side,
- wherein the base portion is configured to abut in a form-fitted manner against an opening of the valve housing,
- wherein the valve housing carrier comprises an extension which is form-fitted to the inner opening of the base portion of the sealing diaphragm, and
- wherein the base portion of the sealing diaphragm is configured to be received between the valve housing and the drive unit in such a way that the opening of the valve housing is sealed in a fluid-tight manner towards the drive unit.
A fluid valve, comprising:
- a magnetic drive unit for a valve closing body,
- wherein the drive unit comprises a core, a coil partially surrounding the core, and an armature movable by the energization of the coil and the resulting magnetic force,
- wherein the valve closing body partially projects into a valve housing,
- wherein the valve closing body is in operative connection with the armature,
- wherein the valve closing body can be pivoted about a pivot axis in at least a first and a second pivot position by the movement of the armature,
- wherein a fluid connection in the valve housing is switched by the pivot position of the valve closing body,
- wherein the portion of the valve closing body projecting into the valve housing is surrounded on the free-end side by a sealing diaphragm,
- wherein the sealing diaphragm is of hat-like design and surrounds the portion of the valve closing body projecting into the valve housing in a fluid-tight manner,
- wherein the sealing diaphragm has a base portion, which is formed to be rotationally asymmetrical on the outer circumferential side and abuts in interlocking manner against an opening of the valve housing,
- wherein the drive unit further comprises a valve housing carrier configured to couple to the valve housing,
- wherein the valve housing carrier comprises an extension which is form-fitted to the inner opening of the base portion of the sealing diaphragm, and
- wherein the base portion of the sealing diaphragm is received between the valve housing and the drive unit in such a way that the opening of the valve housing is sealed in a fluid-tight manner towards the drive unit.
