Embodiment 1

[0023] First, refer to Figure 1 ~ Figure 3 The valve connector and the connection structure of two valve connectors involved in Embodiment 1 of the present invention will be described as follows.

[0024] As shown in the figure, the valve connector 1 has a main pipe 11 connected by a fluid pipeline, a connecting head 12 connected to the main pipe, a connecting port 121 on the connecting head, and a sealing structure is arranged on the inner wall of the connecting port 121, and is installed inside the connecting head 12 The valve 13; wherein the valve 13 has a valve core 131, a valve seat 132 and a control structure valve handle 133; the control structure valve handle 133 includes making the valve 13 when the valve connector 1 is not connected to another valve connector 2 2 o'clock keep the reset device (not shown) that closes, and it can be magnetic force or elastic force etc. When the valve connector one 1 is connected to another valve connector two 2 , the force bearing me...

Embodiment 2

[0029] as attached Figure 4 As shown, the two valve connectors 1 and 2 in Embodiment 2 of the present invention are generally in the same structure as the valve connectors 1 and 2 involved in Embodiment 1, and the only difference lies in the structure of the valve 13 and the force-bearing part 134 There are differences in the settings. Meanwhile, the structures of the connected valve connectors 1 and 2 are exactly the same.

[0030]First, the force-bearing part 134 of the valve connector 1 is located at the end of the valve handle 133, on which the permanent magnet 136 is arranged, and the permanent magnet 141 is also arranged on the force-applying part 14, while another valve connector 2 2 is connected to the valve Device 1 has exactly the same structure. When the valve connector one 1 is connected with another valve connector two 2, the force-applying parts 14, 15 can drive the force-bearing parts 134, 234 in contact or non-contact through the attraction or repulsion forc...

Embodiment 3

[0033] as attached Figure 5 As shown, the two valve connectors 1 , 2 in Embodiment 3 of the present invention are substantially identical in structure to the valve connectors 1 , 2 involved in Embodiment 1, and the only difference lies in the structure of the valve 13 . Meanwhile, the structures of the connected valve connectors 1 and 2 are exactly the same. Any one of the ones described in Embodiments 1 and 2 can be used as the force-bearing part of the valve connector.

[0034] Compared with Embodiment 1, the valve handle shaft in Embodiment 3 is no longer directly connected to the valve core through the swing arm, but is directly arranged on the inner wall of the connecting head. as attached Figure 5 As shown, the valve handle 133 of the valve connector 1 is directly connected to the valve core 131 , and the end of the valve core 131 is rotatably connected to the inner wall of the connector 12 through the valve handle shaft 135 . Correspondingly, the shape of the valve...

Abstract

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.

Description

technical field [0001] The invention relates to the field of valve connectors, in particular to a valve connector for preventing mis-closing and its application on an angled cock. Background technique [0002] The angle cock is installed on the train pipe at both ends of the locomotive and the vehicle, and is located between the train pipe and the brake hose. The angled cock is actually a switch that uses a handle to manipulate the air passage between the train and the brake hose, so as to close the passage at the rear of the train and safely remove and hang the vehicle. When the train is running, except for the two corner cocks at the front and rear of the train, which should be in the closed position, each corner cock in the rest of the construction should be in the open position, so that the train pipe can realize the delivery of pressure air and control the train braking and release. The two major tasks of action, when the handle of the angle plug door is parallel to th...
