摘要
A bottom deflection valve uses a fixed tube casing that defines an internal bullet seat. When a blow -up ball is fixed,the differential fluid pressure shall be diverted to a ring area adjacent to a first sliding tube housing. The sliding tube casing slides in response to differential pressure when dividing a test piece.and opens doors to the drilling ring. Processing or maintenance operations may then be carried out through doors which may be equipped with nozzles. A second sliding tubea casing independent of the first operates in response to the fall of a second bullet inside the device. The second bullet displaces the differential fluid pressure in a ring region adjacent to the second tube casingand movement occurs when a division experiment is submitted to a division. The second tube casing covers the doors to the drilling ring and closes the valve. After moving a sliding tube housingthe pressure along the tubular casing is balanced by allowing the reverse flow without the risk of accidental activation of the tubular casing; Bullet.
