Title: Valve for aggressive media - having flanged, elastic tubular seal of fluorinated resin sepg valve housing and valve operating parts
Inventor: DETTMANN HEINRICH DIPL ING
IPC: F16K11/044
Filed: 1974-12-03
Abstract: Valve for aggressive media has connected valve housing and valve-operating parts sepd. by an elastic tubular seal having a circular cross section, and produced by rotational casting/sintering an acid-resistant fluorinated resin, esp. PTFE, PFA, FEP or "TEFZEL" (RTM). Between the valve-operating part and the valve housing, the outer edge of an elastic flange is supported against a flat or concave plate and stretched by the axial force caused by the inner pressure of the valve, this acting on the annular supporting face of the flange, when the tube is in the central position, or portionwise on the centre of rotation formed by the curved transition of the seal, when the tube is moved out of the central position. An operating lever, pref. in the form of a flexible spring engages within the tube in the central point of its conical end, and this lever is mounted in the support plate in the same plane as the centre of rotation of the tube. The free end of the tube, which is pref. in the form of a ball-and-socket joint, transmits the movements of the valve-operating part onto a slide produced from PTFE or a similar resin, and placed in the axis of the valve seating, the longitudinal ribs of this slide sliding within a boring of the valve housing to form sealing seatings, and enabling one valve seating to be closed, and the other valve seating to be opened. The device has excellent resistance to aggressive media; contains components easily produced by injection moulding or similar methods; is easily operated, esp. as a three-way valve, without requiring large, expensive operating parts, and can be operated at high pressures.
