<p>The invention relates to multiple valve with extra tough sealing perfonnance which consists of valve house, side valve house,control component (dynamoelectric, hand-operated, pneumatic), supporting, gearing and combinatorial valve seat, combinatorial valve member. Wherein said control component connects with two initiative gears and two passive gears of the gearing, all of these elements compose a linkage component.The control component controls the combinatorial valve member (a) directly and the two passive gears of the linkage component controls the combinatorial valve member (b) directly and independently , two independent seal elements are setted on the channel of valve house. Moreover, the sealing valve member is made of extra tough alloy or daubed by the alloy. The multiple valve can seal solely or complex, and protect each other. The multiple valve can be used in the electric and landification environment where the temperature and pressure are high.</p> |
