The invention discloses a device for controlling the opening and closing of a flow channel by using the air pressure of an air spring rubber air bag, which comprises an air pressure control part and a valve part, the air pressure control part is provided with an air pressure space and a pressure conduction part, a communication air channel is arranged between the air pressure space and the rubber air bag, and the air pressure in the air pressure space is equal to the air pressure in the rubber air bag. The valve part is arranged on the liquid filling flow channel and is provided with a gate valve piece enabling the liquid filling flow channel to be in a closed or opened state, one end of the pressure conduction component bears the air pressure of the air pressure space, the other end of the pressure conduction component acts on the gate valve piece, and when the pressure conduction component is applied, the air pressure of the air pressure space controls the gate valve piece to be closed or opened through the pressure conduction component. The device has the advantages that the device replaces a conventional automatic control system to control the opening and closing of the flow channel, so that the arrangement is simplified, and the cost is reduced; the application reliability is enhanced; the device is small in size and does not need to occupy a large installation space.
本发明公开了一种利用空气弹簧橡胶气囊的气压控制流道关开的装置,包括气压控制部和阀门部,所述气压控制部具有气压空间和压力传导部件,所述气压空间与橡胶气囊之间有连通气道,气压空间与橡胶气囊内的气压压力相等,所述阀门部设在充液流道上,其具有使充液流道处于关闭或打开状态的闸阀件,所述压力传导部件的一端承受气压空间的气压压力,另一端作用在闸阀件上,应用时,由气压空间的气压压力通过压力传导部件控制闸阀件的关闭或打开。其优点在于:由本装置替代惯用的自动控制系统控制流道关、开,简化了设置,降低了成本;增强了应用的可靠性;装置体积小,不需占用大的安装空间。
