VALVE AND DIAPHRAGM FOR A VALVE

摘要

A valve has a valve housing with a first port and a second port, and has a closing member movable along an axial direction. When in a closed position, the closing member interacts sealingly with a valve seat to block a fluid connection between the first and second ports. An fluid-impermeable diaphragm comprises a central opening through which a closing member arrangement including the closing member extends, and a clamping section that runs in a clamping gap. The diaphragm is held with sealing action between the closing member arrangement and a holding arrangement on the housing. The diaphragm has a first section and a second section adjoining the first section. The first section is held in the holding arrangement with a force fit, the second section is guided in the holding arrangement, and the first and second sections are arranged at an angle relative to one another. A form fit is generated by the first section, second section and holding arrangement.

主权项

1. A valve with a valve housing, the valve comprising:
a first port and a second port; a closing member is movable along an axial direction and can be brought into a closed position in which the closing member interacts sealingly with a valve seat arranged between the first port and the second port to block a fluid connection between the first port and the second port; and a fluid-impermeable diaphragm that comprises a central opening penetrated by a closing member arrangement comprising the closing member and a clamping section in a clamping gap aligned obliquely to the axial direction; wherein: the diaphragm is held with a sealing effect on the closing member arrangement and on a valve-housing-side holding arrangement; the diaphragm has a first section located on an outer edge, a second section abutting the first section radially to the inside and a third section corresponding to the clamping section abutting the second section radially to the inside; the first section is held in a force fit in the holding arrangement; the second section is guided in the holding arrangement; the first section and the second section are arranged at an angle relative to each other; and the holding arrangement is configured such that the first section, the second section and the holding arrangement form a form fit.
