The invention relates to a valve connector capable of preventing mistaken closing, which is technically characterized by comprising a main pipe communicated with a fluid pipeline, a connector connected onto the main pipe and a valve mounted inside the connector, and the valve is provided with a control structure. The valve connector is characterized in that the control structure comprises a resetdevice enabling the valve to be kept closed when the valve connector is not connected, and a stress component enabling the valve of the valve connector to be opened through a force application component on the other valve connector when the valve connector is connected with the other valve connector. The valve connector is further provided with a force application component capable of applying force to the stress component of the other same valve connector, and the valve in the other valve connector can be opened through the stress component by applying force. Therefore, the valve connector disclosed by the invention can ensure that the valve is kept in an open state when the valve is connected; when the valve is disconnected, the valve is kept in a closed state. By adopting the valve connector to replace an angle cock in the prior art, a valve of the angle cock of a train can be prevented from being closed by mistake, and safety accidents caused by the fact that the angle cock is closed by mistake in the running process of the train are avoided.

    本发明涉及一种防止误关的阀门连接器,所述阀门连接器其包含如下技术特征:与流体管道连通的主管,连接在主管上的连接头,安装在连接头内部的阀门,其中该阀门具有控制结构;其特征在于所述控制结构包含使该阀门在该阀门连接器不连接时保持关闭的复位装置,以及在该阀门连接器与另一阀门连接器进行连接时,通过另一阀门连接器上的施力部件使该阀门连接器的阀门打开的受力部件。其中该阀门连接器上还具有可以对另一相同的阀门连接器的受力部件进行施力的施力部件,通过施力可以通过受力部件使另一阀门连接器中的阀门打开。因此,本发明的阀门连接器可以保证阀门连接时,阀门保持着打开的状态;阀门断开时,阀门保持关闭的状态。通过采用本发明阀门连接器替代现有技术中的折角塞门,可以防止列车的折角塞门的阀门被误关,避免列车行驶过程中因为折角塞门被误关而造成的安全事故。
