Abstract: The closing device (16) moves between a position that opens a valve and a position that closes a valve (14), which is specifically a drainage valve used on a chemical reactor (1), a storage vat, a column or other container, and it comprises an interior housing (30) designed to hold a measurement or detection probe (27). It has an opening (38) that is accessible when it is in the operating position inside the valve and which provides access to its interior housing, allowing the probe to be inserted or removed without the need for prior disassembly of either the valve or the closing device. This invention is of interest to the chemical industry, particularly manufacturers and users of temperature measurement devices.

Abstract: A valve seating (23) is made from a fluoridated polymer, for example, solid glass-coated PTFE or reinforced PFA. At least one electrode (24) is attached to or integral with the valve seating and made of conductive material, such as graphite-TEFLON®, that is compatible with the valve seating. The valve seating is especially for use in conjunction with a device for verifying the integrity of an enamel coating of the “enamel-test” type. The valve seating is then used on the waste valve (11) of the container to be checked and two electrodes (24) are disposed so as to be in contact with the contents (8).

It comprises at least one electrode (24) attached to or integral with said seating and made of conductive material that is compatible with the seating, for example, graphite-Teflon. The valve seating according to the invention is especially for use in conjunction with a device for verifying the integrity of an enamel coating, of the <<enamel-test>> type. The seating is then used on the waste valve (11) of the container to be checked and it comprises two electrodes (24) disposed so as to be in contact with the contents (8). This invention is of interest to the chemical industry, particularly manufacturers and users of <<enamel-test>> devices.
