Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of safety valve for pressure pipeline, including pipeline 1 and valve
Shell 3, the both ends of pipeline 1 have been fixedly connected with ring flange, and the upside of pipeline 1 offers pressure conduction mouth 2, pressure conduction mouth 2
Outside is provided with valve casing 3, and the bottom of valve casing 3 is fixedly connected with connecting plate 4, and valve casing 3 and connecting plate 4 are formed in one structure, connection
The madial wall of plate 4 is equal with the lateral wall radian of pipeline 1, and the lateral wall of connecting plate 4 and pipeline 1 welds；Identical radian can
It is the firmer of the lateral wall welding of connecting plate 4 and pipeline 1.
The inside of valve casing 3 is provided with pressure sensitive spring 5, and the bottom of pressure sensitive spring 5 is fixedly connected with sealing sliding block 6,
