(充气,气囊)进口膨胀式蝶阀性能描述 Performance description

锂电专用(充气,气囊)膨胀式蝶阀 采用气体压力使阀座向着阀板伸展，以便于随时为密封提供均匀分布的压力。由于在阀门的开启和关闭期间，阀板和阀座只会民生瞬时接触，从而使阀板仅受到轻微的摩擦 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

阀座设计特点 Valve seat design features

当阀板打开时，阀座舒展，介质完全通过 When the valve plate is opened, the valve seat stretches and the medium passes through completely

当阀板向关闭位置运动时，阀座仍然保持舒展状态，阀板与阀座之间摩擦很小，介质少量通过 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

阀板关闭时，阀座仍然保持舒展状态，阀板与阀座之间摩擦很小，介质微量通过 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

阀板关闭后，阀座与阀体间的气囊充气膨胀，阀座向阀板收缩，从而提供阀座与阀板之间更紧密的密封 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

阀板关闭，阀座保持绷紧收缩状态，直至接收到阀板打开指令时，阀体与阀座之间气囊放气，阀座先从收缩绷紧状态变为舒展状态，阀板再轻松打开 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

膨胀式密封系统 Expansion sealing system

阀座的设计使得阀体和阀座有一个连续、可变形空腔。当阀板关闭后，阀座在外部气源的压力下，慢慢膨胀并抱紧阀板以达到密封的效果。需要开启式，空腔内的压力会快速排空让阀座收缩以释放阀板，然后再行打开阀板。因而，在启闭过程中，阀座和阀板的接触时间和接触面积都非常之少。阀门的操作扭矩比传统蝶阀降低85%，阀板和阀座之间的磨损率减少了约98%，同时，阀门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

关闭，未密封状态 Closed, unsealed

当阀门运动到关闭位置时，阀板只瞬间接触阀座，从而减低摩擦、磨损和扭矩的需求 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

关闭，密封状态 Closed, sealed

阀门关闭后，阀座向着阀板迅速膨账，从而提供了更大密封面，并对阀板形成包围式密封 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

打开，未密封状态 Open, unsealed

打开阀门前，阀座先排气收缩，然后阀板自由转动至开启位置 Before opening the valve, the valve seat shall exhaust and contract, and then the valve plate shall rotate freely to the open position
