Title:
WEDGE-TYPE GATE PLATE AND SEAT RING MATING PROCESS AND MATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/052370
Kind Code:
A1
Abstract:
A wedge-type gate plate and seat ring mating process and mating device. The mating device comprises a vibration table; the vibration table comprises a vibration mechanism (2) and a positioning mechanism (3), and the positioning mechanism (3) is mounted on the vibration mechanism (2) and is adapted to fix a valve body (8) to be mated; the vibration mechanism (2) is suitable for starting vibration when said valve body (8) is fixed on the positioning mechanism (3) and the wedge-type gate plate (7) is placed in an interval between two seat rings (6), so that the wedge-type gate plate (7) falls under the action of its own gravity and vibration until the sealing surfaces of the two ends of the wedge-type gate plate (7) are attached to the sealing mating surfaces of the two seat rings (6). The mating efficiency is improved, the efficiency is improved by 80%, and technical requirements for operators are reduced.
