Problems solved by technology
[0002] As a medium conveying channel, the flow channel can be seen everywhere in people's life. However, when the flow channel is in use, one of the positions is prone to breakage. When the flow channel breaks, the medium in the flow channel will leak from the broken part of the flow channel. , causing unnecessary trouble, if the medium is a toxic substance, it will cause huge losses

The invention relates to a cut-off apparatus for a medium in a flow channel, comprising an ejection piece, a spacer and a support seat, wherein the ejection piece, the spacer and the support seat are arranged successively along medium flow direction. A through hole A, a through hole B and a through hole C for medium passing are respectively arranged on the support seat, the spacer and the ejection piece. The through hole B and the through hole C are staggered arranged. The ejection piece extends toward one side of the support seat and forms a push rod. A hole for push rod passing is arranged on the spacer, and the spacer forms an axial sliding match with the push rod. A limit structure is arranged between the ejection piece and the spacer, wherein the limit structure is used to limit circumferentially relative rotations of the ejection piece and the spacer. A position on the support seat is extended toward one side of the ejection piece and forms a bracing piece, wherein the position is corresponding to the push rod, and the bracing piece abuts against the push rod. A gap is arranged between the spacer and the ejection piece. Adopting the above technical scheme, the invention provides a cut-off apparatus for the medium in the flow channel. The apparatus can timely cut-off the medium when the flow channel fractures, with the apparatus, occurrence of the medium escaping from the fracture position of the flow channel can be effectively avoided.
Description
technical field [0001] The invention relates to a medium cut-off device in a flow channel. Background technique [0002] As a medium conveying channel, the flow channel can be seen everywhere in people's life. However, when the flow channel is in use, one of the positions is prone to breakage. When the flow channel breaks, the medium in the flow channel will leak from the broken part of the flow channel. , causing unnecessary trouble, if the medium is a toxic substance, it will cause huge losses. Contents of the invention [0003] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a medium cut-off device in the flow channel, which can cut off the medium in time when the flow channel breaks, thereby effectively preventing the medium from leaking from the break of the flow channel phenomenon occurs. [0004] The technical solution of the present invention: a medium cut-off device in the flow channel, which is...
