Part is connected.
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.
As Figure 1-Figure 5, the present invention provides a kind of check valve with heat preservation mechanism, including valve body, valve deck and
Flap, is covered with heat preservation mechanism outside the check valve, the heat preservation mechanism includes babinet and lock ring, and the babinet includes symmetrical junction
The first half and lower half that structure is set, the first half includes pars intermedia and the extension of both sides, the pars intermedia cover on valve
Portion outdoors, extension are covered on the outside of the pipeline being connected, and the pars intermedia and extension are arcuate structure, the first half
It is used in combination with lower board unit, is fixed outside the extensions of both sides using lock ring, the lock ring lower ending opening and is provided with
