Abstract

The invention discloses a pilot-operated type vacuum valve including a valve body, a lifting body and a screw rod driving mechanism. The valve body includes a valve framework and valve body vertical plates, wherein the valve body vertical plates and the valve framework are arranged at intervals front and back. A vacuum plate valve cavity is installed in the middle of the valve body. The lifting body is installed in the vacuum plate valve cavity and slidably connected with the valve body. The lifting body includes a lifting vertical plate, plate valve lifting doors and a plate valve opening andclosing mechanism. The lifting vertical plate is a horizontal and straight mounting plate. The top of the lifting vertical plate is connected with the screw rod driving mechanism. The plate valve lifting doors are symmetrically installed on the both sides of the lifting vertical plate separately. The plate valve opening and closing mechanism is installed between the plate valve lifting doors. According to the pilot-operated type vacuum valve, intermittent double-valve sealing is achieved by using single power, first closing and first passing of a pre-opening and pre-closing air leading hole can be completed through an automatic compaction mechanism, The pilot-operated type vacuum valve is stable in performance, and energy conservation and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a pilot-operated vacuum valve. Background technique [0002] At present, most of the airtight drying rooms use a hot blower to heat the drying object for a long time and dry the water. After the drying object itself removes part of the water, it needs to enter the next station for more effective drying, especially the more demanding This is especially true for high drying objects. For example, the drying object is a lithium-ion battery, and water, as a trace component in the electrolyte, has a certain influence on the formation of the selective permeable membrane of the lithium-ion battery and the performance of the battery. In the process, the humidity of the environment and the water content of the positive and negative materials and the electrolyte must be strictly controlled. Before or after the trolley equipped with drying objects on the automatic line goes to the...
