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 making the premise of creative work
Lower obtained every other embodiment, belong to the scope of protection of the present utility model.
As shown in Figure 1 and Figure 2, a kind of gravity-held check valve, the gravity-held check valve have first component 1 and second
Part 2, the first component 1 are provided with entrance 11, and second component is provided with outlet 21, and the outlet 21 is positioned at the upper of entrance 11
Side, the second component 2 are provided with stopper 22；
The first component 1 is connected with each other with second component 2 and is collectively forming an inside die cavity, the outlet 21 and entrance 11
Being communicated with the die cavity, the stopper 22 is located in the die cavity, and the sealing part 3 of an activity is additionally provided with inside the die cavity,
When the gravity-held check valve is in sealing state, the sealing part 3 is located at the entrance 11 by self gravitation, and complete
The entrance 11 is blocked entirely, and when the gravity-held check valve is in boiling water state, the sealing part 3 relies on the impact band of water
It is dynamic to be resisted against on the stopper 22.
The first component 1 has a U-typed die cavity, and its bottom is in dome-type, and the U-typed cavity bottom is provided with described
Entrance 11, the second component 2 have a valve pipe, and one end of the valve pipe is provided with some stoppers 22, each stopper
Between there is gap, the valve pipe is provided with one end of the stopper 22 and the opening of the U-typed die cavity of the first component 1 connects
