Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The all other embodiment obtained, shall fall within the protection scope of the present invention.
Refering to fig. 1 shown in -2, automatically reset sampling cock, including probe tube (3), cock valve (1) and out sample tube (4), takes
Sample pipe (3) and out sample tube (4) are sealingly fastened in the both ends of cock valve (1) respectively, and the cock valve (1) is by valve seat (11), valve block
(19), valve rod (121), ball nut (13), interconnecting piece, handle (22) and limit protrusion (15) composition, the handle (22) are
The body of rod of inner hollow, interconnecting piece include connecting plate (14) and branch sleeve (2), and connecting plate (14) is fixed with branch sleeve (2)
Connection；Valve block (19) is fixed in valve seat (11) inner cavity, and gasket is filled between valve block (19) and the internal chamber wall of valve seat (11)
