The invention discloses an opening and closing mechanism of an aerodynamic valve. Key points of the technical scheme are as follows: the mechanism comprises a first valve cavity formed in a valve body; a first piston is connected into the first valve cavity in a sliding manner; a first return spring is connected between the first piston and the top of the first valve cavity; a first sliding rod and a second sliding rod are fixed to the two end sides of the first piston correspondingly; a first sliding cavity and a second sliding cavity for the first sliding rod and the second sliding rod to slide are further formed in the valve body; a first air inlet, a second air inlet, a first air outlet and a second air outlet which are communicated with the first valve cavity are further formed in thevalve body, and a flow channel is formed in the first sliding rod and the first piston jointly. Therefore, the opening and closing mechanism of the aerodynamic valve can directly disconnect the two paths when the pressure is lower, and can simultaneously connect the two paths when the pressure is higher than a certain condition.
本发明公开了一种空气动力阀的开合机构,其技术方案要点是:包括开设在阀体内的第一阀腔,所述第一阀腔内滑移连接有第一活塞,所述第一活塞和所述第一阀腔腔顶之间连接有第一回位弹簧,所述第一活塞的两端侧分别固定有第一滑动杆和第二滑动杆,所述阀体内还开设有供所述第一滑动杆与所述第二滑动杆滑动的第一滑动腔和第二滑动腔,所述阀体内还开设有与所述第一阀腔相互连通的第一进气口、第二进气口、第一出气口和第二出气口,所述第一滑动杆和所述第一活塞内共同开设有流道;故本空气动力阀的开合机构可以在压力较小时直接将两路通路断开,当压力大于一定条件时将两路同时导通。
