Patent CA-2077808-A1 (CA)
Title: Directional gate valve
Inventor: GROTENHUIS JOSEF A
IPC: F16K11/065
Filed: 1992-09-09
Abstract: ABSTRACT OF THE DISCLOSURE            In the present valve, the valve housing consists of two parts, namely a block (10) having a through-hole (11) which is preferably conical and a sleeve (20) which fits, with at least the essential part of its lateral surface, tightly and in a self-sealing manner in this hole and contains the cylindrical through-hole for the control piston (35) of the valve and, in its lateral surface, at least one groove (33 and 34) connecting to one another the two windows (27 and 29) furthest away from one another.  This design makes it possible on the one hand  for the  connecting  line between  the two windows   furthest  apart  to  be  produced   in  a substantially simpler manner than in the past.  Since the life of a valve is limited by the leakage resulting from the wear between the slide and the longitudinal hole, in the valve according to the invention it is possible on the other hand, after leakage occurs, of replace the sleeve and the slide so that the expensive replacement of the entire valve can be dispensed with, permitting a substantial reduction in the maintenance costs.
