Embodiment 2

[0108] Most of the structure of the fire cover of embodiment 2 of the present invention is identical with embodiment 1, and difference is:

[0109] like Figure 10 As shown, the radial distance between the inner surface 421 of the vertical stop 42 and the axis of the outer ring 1 gradually decreases along the direction away from the upper cover surface 2, that is, the inner surface 421 of the vertical stop 42 gradually approaches the axis of the outer ring 1 . When the fire cover 100 was installed on the fire cover mounting seat 200, the inner surface 421 of the vertical baffle 42 had a certain inclination, so that the dripping speed of the liquid attached to the inner surface 421 of the vertical baffle 42 would slow down, and the liquid dripped The impact force is reduced when falling.

[0110] like Figure 10 As shown, the radial distance between the outer surface 422 of the vertical stop 42 and the axis of the outer ring 1 gradually increases along the direction away fro...

Abstract

The invention discloses a burner cap. The burner cap comprises an annular outer ring, an upper cap face, a waterproof eave and a plurality of flame stabilizing holes; the upper end face is located onthe end face of the outer ring, and a gas mixing chamber is formed between the inner circumferential face of the outer ring and the upper cap face; the waterproof eave is arranged along the outer circumferential face of the upper cap face; and the flame stabilizing holes are formed in the mode of penetrating the outer ring and enable the gas mixing chamber to communicate with an external space, and the extension line of at least one flame stabilizing hole extends to the waterproof eave. According to the burner cap, the waterproof eave is arranged along the outer circumferential face of the upper cap face, the extension lines of the flame stabilizing holes are made to extend to the waterproof eave, that is, outlets of the flame stabilizing holes are located in a safe space formed between the waterproof eave and the outer circumferential face of the outer ring, thus flames in the flame stabilizing holes can keep stable and cannot be extinguished by overflowing liquid, the flame stabilizing holes are also not blocked due to entering of the liquid, and the flame stabilizing effect is good.

Description

technical field [0001] The present invention relates to a fire cover. Background technique [0002] The flame-stabilizing methods adopted by the existing fire covers on the market can basically be divided into the flame-stabilizing methods of large and small holes or flame-stabilizing grooves. The way of stabilizing the flame with large and small holes, that is, setting small diameter stabilizing holes around the main flame hole, but the stabilizing holes used for stabilizing the flame will be disturbed by cold air, and the combustion of the stabilizing holes is unstable, so the flame stabilizing effect is general ; The flame-stabilizing way of the flame-stabilizing groove, because the flame-stabilizing groove is used under bad conditions for a long time, it is easy to cause the flame-stabilizing groove to be blocked. [0003] The way of stabilizing the flame with large and small holes, because the diameter of the flame stabilizing hole is small, the stabilizing flame hole ...
