Specific embodiment

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 making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment

Fig. 1-Fig. 6 is please referred to, the utility model provides a kind of technical solution: a kind of combustion gas low-temperature safety valve, including main body, It further include safety device and clamping device, main body includes venthole 6 and protective shell 8, and safety device includes valve 4, and valve 4 is located at The top of protective shell 8, the top surface of valve 4 offer limiting tooth 2, and the top center of valve 4 is fixedly connected with outer tube sleeve 9, The inside of outer tube sleeve 9, which is connected together, second spring 13, and the top engaging of second spring 13 is connected with inner tube set 12, outer tube sleeve 9 Outside be connected together and have the first spring 10, the top of valve 4 is provided with capstan 3, and the inside fixation of capstan 3 offers limiting slot 11。

For the ease of guaranteeing the normal use of clamping device, in the present embodiment, it is preferred that clamping device includes upper ring cap 5 With lower ring set 7, upper ring cap 5 and lower ring set 7 are located at the two sides up and down of venthole 6, and the side of protective shell 8 is fixedly connected with Determine bolt 14, being connected together inside the side of upper ring cap 5 and lower ring set 7 has third spring 15, and the inside of third spring 15 is fixed It is connected with limited post 16.

For the ease of guaranteeing the normal use of connecting tube 1, in the present embodiment, it is preferred that main body further includes connecting tube 1, is protected The side integral type of protective case 8 is connected with connecting tube 1, and the other side integral type of protective shell 8 is connected with venthole 6.
