The bottom sealing member 142 can be easily mounted to the inner valve cover 130 to form one assembly, and the assembly formed by the bottom sealing member 142 and the inner valve cover 130 is interposed between the upper valve cover 110 and the lower valve cover 120 when the steam valve 100 is assembled, resulting in higher assembly efficiency.

The inner side of the top cover sidewall 112 may abut the outer side of the bottom seal 142. Thereby, a seal can be formed there, thereby improving the sealability of the steam valve 100. Of course, the inside surface of the upper cap sidewall 112 may also have a gap with the outside surface of the bottom seal 142 in view of manufacturing tolerances and/or mounting gaps. I.e., there may be a small gap between the bottom seal 142 and the upper cap sidewall 112, which does not form a seal.

As shown in fig. 4 and 5, one of the lower and upper cover sidewalls 122 and 112 may be provided with a catch 160 protruding in a radial direction at intervals. The catch 160 projects radially from the surface of the side wall on which it is located. For example, three circumferentially spaced snaps 160 may be provided. The other of the lower cover sidewall 122 and the upper cover sidewall 112 may be provided with a catching groove 170 at intervals. For example, three circumferentially spaced snap grooves 170 may be provided. For example, in the illustrated embodiment, the lower lid side wall 122 is provided with a catch 160, and the upper lid side wall 112 is provided with a catch groove 170; if needed and/or desired, the lower lid side wall 122 is provided with a snap groove 170 and the upper lid side wall 112 is provided with a snap 160.

The catching groove 170 is configured as an elongated groove extending in the circumferential direction. One end of the catch groove 170 may be provided with an opening for the catch 160 to enter, so that the catch 160 enters and moves in the catch groove 170 through the opening. In this embodiment, the valve upper cover 110 or the valve lower cover 120 can be rotated to move the latch 160 from one end of the latch groove 170 to the other end thereof, and the latch 160 is limited by the latch groove 170, so that the valve upper cover 110 and the valve lower cover 120 are fixed in position in the axial direction and do not move relative to each other in the axial direction.

The other end of the catching groove 170 opposite to the one end may be provided with a protrusion 171 protruding in a radial direction. The protrusion 171 protrudes in a radial direction from a side surface of the catching groove 170. The clip 160 can move in the clip groove 170 past the tab 171 and then clip to the tab 171. The catch 160 is accessible from the opening of the cavity 124 and is circumferentially movable within the cavity 124, the catch 160 circumferentially engaging the stud 171 when moving past the stud 171. The upper valve cover 110 and the lower valve cover 120 are circumferentially fixed in position by the engagement of the snap 160 and the male snap 171, and are not circumferentially movable relative to each other. Thereby, the rotary clamping of the valve upper cover 110 and the valve lower cover 120 is realized.

The catch 160 may be configured in an elongated shape extending in the circumferential direction. In other words, the catch 160 is an elongated block. An end of the catch 160 corresponding to the position of the male catch 171 may be provided with a groove 161 recessed in the radial direction. The male clasp 171 can snap into the groove 161. Thus, by means of the elongated clip 160, the area in which the axially facing surfaces of the clip 160 and the clip groove 170 abut against each other can be increased, so that the valve upper cover 110 and the valve lower cover 120 are more stably connected in the axial direction, thereby improving the structural stability of the steam valve 100. This end of the catch 160 has an end face facing in the circumferential direction. The end surface may be provided with a guide surface 162 inclined in the circumferential direction. Thereby, the catch 160 can be easily moved past the convex catch 171.

The valve upper cover 110 is made of a transparent material. As shown in fig. 6, an upper surface of the inner valve cover 130 facing the upper valve cover 110 may be provided with a cubic pattern 134. The user can see the three-dimensional pattern 134 on the valve inner cover 130 through the valve upper cover 110, and the three-dimensional pattern 134 can be arbitrarily set according to the user's needs, which improves the degree of freedom in designing the steam valve 100. Thus, while ensuring the basic function of the steam valve 100 of exhausting gas over-spill prevention, the steam valve 100 may also have a novel and aesthetic appearance, which brings a novel visual impression to the user, improving the user experience. Optionally, the relief 134 is configured as a spiral about the centerline of the valve inner cover 130. Therefore, the valve inner cover 130 with the three-dimensional patterns 134 can be conveniently produced and manufactured.

As shown in fig. 7, the inner surface of the valve inner lid 130 may be provided with a spill prevention rib 135 extending downward. The spill prevention rib 135 is located on a side of the air outlet 131 away from the center line of the valve inner cover 130. The spill prevention rib 135 may be arranged around the air outlet 131, for example, in a ring shape. Referring back to fig. 2 and 4, the bottom wall of the valve lower cover 120 may be integrally configured with a semi-closed air intake passage portion 125. The top of the air intake passage portion 125 can be close to the spill prevention rib 135, and the inlet 126 of the air intake passage portion 125 is located on the side of the spill prevention rib 135 away from the center line of the valve inner cover 130. The inlet 126 of the intake passage portion 125 faces outward, i.e., away from the center of the lower valve cover 120. The steam introduced from the inlet 126 flows in a space between the intake passage portion 125 and the valve inner cover 130.

In this embodiment, a narrow vapor flow passage may be formed between the overflow preventing rib 135 and the top of the air intake passage portion 125, and thus, if vapor is entrained with liquid or foam, the vapor can flow through the narrow vapor flow passage substantially smoothly even under the influence of air flow fluctuations, and the vapor entrained with the liquid or foam is prevented from overflowing the air outlet 131, and the overflow preventing effect is good.

The intake passage portion 125 may be disposed away from the center of the valve lower cover 120. The intake passage portion 125 may include an inside intake portion 127 and an outside intake portion 128. The inner intake portion 127 extends upward from the bottom wall of the valve lower cover 120 and is provided with an inlet 126. The inside air intake portion 127 is configured as a semi-cylindrical body having a top wall. The outside air intake portion 128 extends downward from the bottom wall of the valve lower cover 120 and is provided with an air intake port 121. The outside air intake portion 128 is configured as a cylindrical body with an open bottom. Thereby, the steam flowing path may be extended to allow the steam to smoothly enter the inside of the steam valve 100, and the air inlet passage part 125 may have an anti-overflow and flow-stabilizing function.
