Abstract

A conduit slider for chemical and petrochemical systems, comprising a slider housing (10) which has a blockable conduit (20) and at least one slider plate (30) which can be moved into an open position and a closed position and vice versa. A sealing seat (40) is paired with the conduit (20), said sealing seat extending along the circumference of the conduit (20) and sealing against the slider plate (30) at least in the closed position during operation. The conduit slider ensures the seal between the sealing seat (40) and the slider plate (30) and allows the slider plate (30) to be installed into and removed from the slider housing (10) with a compact, portable, simple, and inexpensive design. This is achieved in that at least one circumferential groove (42) is formed in the sealing seat (40), a molded metal ring (50) with a media filling being arranged in said groove.

Abstract

A triple sealing seat is provided in a conduit gate valve having at least one shut-off plate which is displaceable between an open and closed position with respect to the conduit. The triple sealing seat forms a substantially annular sealing surface. In order to increase the tightness, the annular sealing surface comprises a radial interior sealing and scraping edge which can be contacted with the shut-off plate during operation. Also provided is a first circumferential groove located radially further outside which is in communication with a first gas channel and to which a sealing gas pressure can be applied. Also provided is a second circumferential groove located radially further outside which is in communication with a second gas channel and to which a sealing gas pressure can be applied. Moreover a single-plate gate valve and a double-plate gate valve comprising the triple sealing seat are disclosed, along with a method for sealing a shut-off plate of a conduit gate valve by using the triple sealing seat.

Abstract

The invention relates to a slide valve, especially for regulating a catalyser flow or similar high temperature media, said valve comprising a tubular section (10) and a diaphragm (11) which is arranged therein and comprises an inlet and an outlet (12a, 12b) through which a medium flows during operation. Said valve also comprises a slide plate (13) which interacts with the outlet (12b) in order to regulate the catalyst flow and can be displaced into an open or closed position I, II. The slide plate (13) is displaceably mounted by means of meshed guiding elements (14, 15) arranged on the tube side and on the plate side. The invention is characterised in that the tube-side guiding elements (14) are arranged upstream of the outlet (12b) in the flow direction.
