(充氣,氣囊)進口膨脹式蝶閥性能描述 Performance description

鋰電專用(充氣,氣囊)膨脹式蝶閥 采用氣體壓力使閥座向著閥板伸展，以便于隨時為密封提供均勻分布的壓力。由于在閥門的開啟和關閉期間，閥板和閥座只會民生瞬時接觸，從而使閥板僅受到輕微的摩擦 RETZ The expansion butterfly valve (inflatable, air bag) specially used for lithium battery uses gas pressure to extend the valve seat toward the valve plate, so as to provide uniform pressure distribution for sealing at any time. During the opening and closing of the valve, the valve plate and valve seat will only contact with each other instantaneously, so that the valve plate will only suffer slight friction

閥座設計特點 Valve seat design features

當閥板打開時，閥座舒展，介質完全通過 When the valve plate is opened, the valve seat stretches and the medium passes through completely

當閥板向關閉位置運動時，閥座仍然保持舒展狀態，閥板與閥座之間摩擦很小，介質少量通過 When the valve plate moves to the closed position, the valve seat remains in a stretched state, the friction between the valve plate and the valve seat is very small, and a small amount of medium passes through

閥板關閉時，閥座仍然保持舒展狀態，閥板與閥座之間摩擦很小，介質微量通過 retz品牌 When the valve plate is closed, the valve seat remains in a stretched state, the friction between the valve plate and the valve seat is very small, and the medium passes slightly

閥板關閉后，閥座與閥體間的氣囊充氣膨脹，閥座向閥板收縮，從而提供閥座與閥板之間更緊密的密封 After the valve plate is closed, the air bag between the valve seat and the valve body inflates and expands, and the valve seat shrinks towards the valve plate, thus providing a tighter seal between the valve seat and the valve plate

閥板關閉，閥座保持繃緊收縮狀態，直至接收到閥板打開指令時，閥體與閥座之間氣囊放氣，閥座先從收縮繃緊狀態變為舒展狀態，閥板再輕松打開 When the valve plate is closed, the valve seat remains tight and contracted. When the valve plate opening command is received, the air bag between the valve body and the valve seat deflates. The valve seat first changes from the tight and contracted state to the extended state, and then the valve plate is opened easily

膨脹式密封系統 Expansion sealing system

閥座的設計使得閥體和閥座有一個連續、可變形空腔。當閥板關閉后，閥座在外部氣源的壓力下，慢慢膨脹并抱緊閥板以達到密封的效果。需要開啟式，空腔內的壓力會快速排空讓閥座收縮以釋放閥板，然后再行打開閥板。因而，在啟閉過程中，閥座和閥板的接觸時間和接觸面積都非常之少。閥門的操作扭矩比傳統蝶閥降低85%，閥板和閥座之間的磨損率減少了約98%，同時，閥門的密封可靠性得到了大幅提高 The design of valve seat makes the valve body and valve seat have a continuous and deformable cavity. When the valve plate is closed, the valve seat slowly expands under the pressure of the external air source and encloses the valve plate to achieve the sealing effect. Open type is required. The pressure in the cavity will be quickly drained to make the valve seat shrink to release the valve plate, and then open the valve plate. Therefore, in the opening and closing process, the contact time and contact area between the valve seat and the valve plate are very small. The operating torque of the valve is 85% lower than that of the traditional butterfly valve, the wear rate between the valve plate and the valve seat is reduced by about 98%, and the sealing reliability of the valve is greatly improved

關閉，未密封狀態 Closed, unsealed

當閥門運動到關閉位置時，閥板只瞬間接觸閥座，從而減低摩擦、磨損和扭矩的需求 When the valve moves to the closed position, the valve plate only contacts the valve seat instantaneously, thus reducing the need for friction, wear and torque

關閉，密封狀態 Closed, sealed

閥門關閉后，閥座向著閥板迅速膨賬，從而提供了更大密封面，并對閥板形成包圍式密封 After the valve is closed, the valve seat rapidly expands towards the valve plate, providing a larger sealing surface and forming a enveloping seal for the valve plate

打開，未密封狀態 Open, unsealed

打開閥門前，閥座先排氣收縮，然后閥板自由轉動至開啟位置 Before opening the valve, the valve seat shall exhaust and contract, and then the valve plate shall rotate freely to the open position
