The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of relief valve that is used for pressure cooker, comprise weight and the valve gap that is positioned at the weight outside, described weight is cylindrical, the outer surface of described weight has the draw-in groove that circumferentially extends along described weight, described valve gap has the cavity of accommodating described weight, the inwall of described cavity is provided with the back-off adaptive with described draw-in groove, has the gap between the inwall of described cavity and the described weight.
At the relief valve that is used for pressure cooker described in the utility model, described draw-in groove is the annular groove around described one week of weight.
At the relief valve that is used for pressure cooker described in the utility model, described back-off is two projectioies that are arranged on the inwall of described cavity, and two described projectioies are symmetrically distributed.
At the relief valve that is used for pressure cooker described in the utility model, described back-off is a plurality of projectioies that are arranged on the inwall of described cavity, and a plurality of described projectioies circumferentially evenly distribute along the inwall of described cavity.
At the relief valve that is used for pressure cooker described in the utility model, described projection has guiding surface, and described guiding surface is positioned at the downside of described projection.
At the relief valve that is used for pressure cooker described in the utility model, described weight has the host cavity of the blast pipe that is used to accommodate described pressure cooker, and the top of described host cavity has the thimble that is used for the described blast pipe of shutoff.
At the relief valve that is used for pressure cooker described in the utility model, the top of described weight is provided with the steam vent that is communicated with described host cavity.
At the relief valve that is used for pressure cooker described in the utility model, have venthole on the described valve gap over against described steam vent.
At the relief valve that is used for pressure cooker described in the utility model, described valve gap is provided with handle.
Implement the relief valve that is used for pressure cooker of the present utility model, has following beneficial effect: at the relief valve that is used for pressure cooker of the present utility model, weight is provided with draw-in groove, valve gap is provided with the back-off adaptive with draw-in groove, has the gap between weight and the valve gap, overcome the defective of the easy spalling of valve gap of the relief valve of prior art, relief valve of the present utility model has advantages such as simple in structure, safe and reliable, with low cost.
