Embodiment Construction

[0017] The present invention can be explained in detail through the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Such as figure 1 As shown, the ball valve includes an end shell 2, a main shell 3, an O-ring 4, a tail shell 5, a ball core 8, a rotation key 9, and a handle 10; the end shell 2 is located at the front end of the ball valve, and the tail shell 5 is located at At the tail end of the ball valve, the main shell 3 is arranged outside the ball valve; O-rings 4 are respectively arranged between the ball core 8 and the end face shell 2, between the ball core 8 and the tail shell 5, and the handle 10 is connected with the rotation key 9, The turning key 9 is connected with the ball core 8, and the ball core 8 is driven to rotate by turning the handle 10 to realize opening or closing of the ball valve. The hermaphroditic ball valve adds a locking device th...

Abstract

The invention discloses a female-male integrated fluid ball valve capable of preventing mistaken pulling operation. The female-male integrated fluid ball valve capable of preventing the mistaken pulling operation comprises an end face shell, a main shell, an O-shaped ring, a tail shell, a ball core, a rotating key, a handle, a locking device and a locking pin. The female-male integrated ball valvewith the mistaken pulling prevention function not only inherits the characteristics of the small volume and the strong through-current capability specifically own by the ball valve, but also integrates the functions of quick connection and disconnection of a quick connector, meanwhile, through the female-male integration design, the difference of a male head and a female head of the traditional quick connector is complemented, the manufacturing cost is saved, and the connection efficiency is improved; and in addition, the structure integrates the mistaken pulling prevention function, when a medium passes in a pipeline, the situation that connected two valves are disconnected due to misoperation is avoided, and the reliability of connection is ensured.

Description

technical field [0001] The invention relates to a ball valve, in particular to a hermaphroditic fluid ball valve capable of preventing mis-extraction operation. Background technique [0002] The existing ball valve has the function of connecting or disconnecting pipelines. The two ends of the ball valve mostly use threaded joints, and the two ends are connected to the pipeline. When the ball valve is in the disconnected state, the ball valve is sealed by the O-ring between the inner ball core and the interface shell at both ends, so that the pipeline is in the disconnected state. When the handle on the upper end of the ball valve is turned 90°, the transmission key in the middle is driven, and the transmission key drives the ball core to rotate, the internal flow path of the ball core is consistent with the interface flow path, and the ball valve is in an open state. The ball valve of this structure is connected to the pipeline to achieve the purpose of connecting or disco...
