For example, a second sealing member 42 may be disposed between the edge of the upper cover 200 and the edge of the lower cover 10. The second seal 42 may be any type of seal known in the art or that may occur in the future, including but not limited to a seal ring or gasket, etc. The second seal 42 may be the same as or different from the first seal 41. By providing the second sealing member 42, gas leakage and entry of dirt such as dust from the external environment between the upper cover 200 and the lower cover 10 can be prevented, and the sealing performance of the micro-pressure valve 1 is improved, thereby ensuring good performance of the micro-pressure valve 1.

Illustratively, the stopper portion may include a stopper protrusion 110. The limit fitting may include a limit groove 210. The stopper groove 210 may be engaged with the stopper protrusion 110. So set up, the structure of minute-pressure valve 1 is succinct, low in manufacturing cost. In an embodiment not shown in the drawings, the spacing portion may include a spacing groove, and the spacing mating portion may include a spacing protrusion, as long as the spacing portion and the spacing mating portion are in adaptive connection to limit the position of the upper cover assembly 500 along the circumferential direction.
