Problems solved by technology

Existing reciprocating driving device 410 generally adopts motor to drive reciprocating driving door 460 through nut screw structure or rack and pinion to realize opening and closing of airtight doors 430, 440. If the airtight door 430, 440 is kept sealed for a long time by means of motor drive, it is easy to shorten the life of the motor (the motor burns out)
In order to solve this problem, people have designed a cylinder to replace the motor to drive the reciprocating drive door 400, ...

Abstract

The invention discloses a low drop-out transmission valve sealing control method and a low drop-out transmission valve. According to the method, a transmission valve arranged between two adjacent working boxes and used for enabling the working boxes to be connected or disconnected is arranged, a first pressure sensor used for measuring first pressure P1 is arranged in the first working box, a second pressure sensor used for measuring second pressure P2 is arranged in the second working box, a third pressure sensor used for measuring third pressure P0 is arranged in the transmission valve, and a control device is arranged for controlling the state of the third pressure P0 according to the state of the first pressure P1 and the second pressure P2; when P0 is larger than the maximum value (please see the formula in the specification) of P1 and P2, the third pressure P0 is kept unchanged, and a motor is shut off. By the adoption of the low drop-out transmission valve sealing control method and the low drop-out transmission valve, the motor can be protected, and the service life of the motor can be prolonged; meanwhile, the requirement for design of a sealing door opening and closing mechanism can be lowered, and cost can be reduced.

Description

technical field [0001] The invention relates to a sealing control method of a low-pressure differential transmission valve and a low-pressure differential transmission valve, in particular to a sealing control method of a low-pressure differential transmission valve suitable for use in a vacuum tunnel oven for lithium batteries or lithium battery pole pieces and Low differential transfer valve. Background technique [0002] At present, in the production process of new energy materials, it is necessary to bake the new energy materials to remove moisture. For example, the manufacture of lithium-ion battery pole pieces or lithium-ion batteries requires the lithium-ion battery pole pieces or Lithium-ion batteries are deep dried. The most common drying equipment is the internal circulation single box oven, which first puts the baked lithium battery or battery electrode into the vacuum oven, then seals the vacuum oven, and puts it under normal pressure. Next, first heat the bake...
