1. The structure adopts eccentric tightening principle to achieve the purpose of gate tightening, regulating and closing through transmission mechanism. The sealing pair is metal face ring with hard face contact seal. When the double eccentric structure is opened, the valve core is located in the Tibetan sphere chamber, the circulation section is large, and the valve core is not washed out when the valve is closed, and the sphere surface of the valve core is along the valve when the valve is opened. Seat gradual, effective removal of scaling obstacles, to achieve reliable sealing. It is especially effective for mixed-flow transportation of two-phase mixed flow and easy scaling solid precipitation. 2. Valve hemispherical bimetal, base metal surfacing different alloys, valve seat also for the corresponding surfacing after special treatment, sealing surface combination into anti-corrosion, wear resistance, high strength and other types, to meet the needs of different occasions. 3. Close sealing and zero leakage of harmful gases 4. The spool of the sealing pair retains compensation. When the valve is worn out, it rotates a little when it is closed, so that it can seal reliably and prolong its service life. In addition, the user will tighten the nut off, adjust or replace the seat is still available, to avoid the valve seal failure, the whole set scrapped malpractice. |
