Gu of triumphal oil field east factory 3 collect a center to develop a balance successfully recently type is low cut end control valve, make oil field is noted get together pump is noted to much mouth well at the same time get together become a possibility. Because polymer suffers machinery to cut viscosity loss big, when requirement polymer medium is carried, adjust ball valve must a standard-sized sheet or close completely, can cause very big polymer to cut otherwise, because this is noted normally,get together pump can be noted to only get together the well offers polymer mother solution. For this, this center used round cone-shaped design, v alloy data is used in the sealed place of core of a powerful person and valve base, such having stronger be able to bear or endure erode quality, can assure the sealing of valve. Valve transmission system is sealed use step-down technology, can assure valve to adjust agile. The experiment makes clear, this a powerful person has precision of mother liquor adjustment reservation of convenient, viscosity leads tall, field work tall characteristic. Control valve leaves degree when a standard-sized sheet, 2/3, 1/2, 1/4, viscosity reservation rate all is in 98% above. Current, this control valve already declared national patent.
