实施例一：Embodiment 1:

如图1至图6所示，根据本发明一些实施例提供的一种蒸汽阀，包括：阀座10、阀盖20和栅格30。As shown in FIGS. 1 through 6, a steam valve according to some embodiments of the present invention includes a valve seat 10, a valve cover 20, and a grid 30.

A thorough problem, and the problem that the steam chamber of the steam valve is blocked, the defoaming effect is not good, and the cooking time is prolonged due to difficulty in cleaning or incomplete cleaning of the grid 30, that is, the grid 30 is detachably mounted on the valve seat 10 In the above, the cleaning of the grid 30 and the valve seat 10 is facilitated, and the use effect of the steam valve is ensured.

另外，栅格30支撑在阀盖20和阀座10之间，起到对阀盖20良好的支撑作用，有效增强蒸汽阀的结构强度，防止阀盖20因受热而变形，尤其对于尺寸相对较大的蒸汽阀，随着阀盖20的尺寸增大会导致阀盖20的强度降低、易受热变形，通过在阀盖20和阀座10之间增设栅格30，防止阀盖20受热变形的效果更明显。In addition, the grid 30 is supported between the valve cover 20 and the valve seat 10 to provide a good support for the valve cover 20, effectively enhancing the structural strength of the steam valve, and preventing the valve cover 20 from being deformed by heat, especially for relatively large dimensions. The large steam valve, as the size of the valve cover 20 increases, causes the strength of the valve cover 20 to decrease and is susceptible to thermal deformation. By adding a grid 30 between the valve cover 20 and the valve seat 10, the valve cover 20 is prevented from being thermally deformed. More obvious.

拆卸栅格30时，利用塑料栅格30自身变形，向栅格30上第二卡扣304凸出的反方向挤压栅格30，使第二卡扣304向内移动、并从第一卡扣103的下方脱出，实现栅格30从阀座10上拆下进行清洗，解决栅格30在阀座10上安装后不好拆下的问题。When the grid 30 is disassembled, the plastic grid 30 is deformed by itself, and the grid 30 is pressed against the opposite direction of the second buckle 304 on the grid 30, so that the second buckle 304 moves inward and from the first card. The lower portion of the buckle 103 is disengaged, and the grid 30 is removed from the valve seat 10 for cleaning, and the problem that the grid 30 is not removed after being mounted on the valve seat 10 is solved.

换言之，利用第一卡扣103和第二卡扣304的配合余量和栅格30自身变形，实现栅格30容易装配和拆卸的效果，解决了栅格30安装过程中难装配且耗时的问题及安装好后不好拆下的问题。In other words, by utilizing the mating margin of the first buckle 103 and the second buckle 304 and the deformation of the grid 30 itself, the effect of the grid 30 being easily assembled and disassembled is achieved, and the assembly and the time-consuming process of the grid 30 are solved. Problems and problems that are not easy to remove after installation.

在本发明的一个实施例中，如图2和图3所示，栅格30的一端部设有两个第二卡扣304，栅格30的另一端部设有至少一个第二卡扣304，阀座10上设有分别与第二卡扣304对应的第一卡扣103；其中，位于栅格30的一端部的两个第二卡扣304的大小不同，与两个第二卡扣304一一对应的两个第一卡扣103的大小分别与两个第二卡扣304的大小相适配。In one embodiment of the present invention, as shown in FIGS. 2 and 3, one end of the grid 30 is provided with two second buckles 304, and the other end of the grid 30 is provided with at least one second buckle 304. The valve seat 10 is provided with a first buckle 103 corresponding to the second buckle 304 respectively; wherein the two second buckles 304 located at one end of the grid 30 are different in size, and two second buckles The sizes of the two first buckles 103 corresponding to one another are matched with the sizes of the two second buckles 304, respectively.

由于蒸汽阀一般设计为左右对称结构，因此安装在阀座10上的栅格30通常设计成与阀座10的形状相适配的左右对称结构，这样在栅格30的装配过程中容易出现栅格30装反的情况，为了避免栅格30装反，在栅格30的一端部设置一大一小两个第二卡扣304，在阀座10上设置与之对应的一大一小两个第一卡扣103，实现栅格30装配过程中的防呆效果，解决栅格30装配过程中容易装反的问题。Since the steam valve is generally designed to be a bilaterally symmetrical structure, the grid 30 mounted on the valve seat 10 is generally designed to have a bilaterally symmetrical structure that matches the shape of the valve seat 10, such that the grid 30 has been assembled. In the process, the grid 30 is easily reversed. In order to avoid the reverse of the grid 30, two large and two second buckles 304 are disposed at one end of the grid 30, and the valve seat 10 is provided with a corresponding one. One large and one small first buckle 103 realizes the foolproof effect in the assembly process of the grid 30, and solves the problem that the grid 30 is easy to be reversed during assembly.

在本发明的另一个实施例中，栅格30的一端部设有两个第二卡扣304，栅格30的另一端部设有至少一个第二卡扣304，阀座10上设有分别与第二卡扣304对应的第一卡扣103；其中，栅格30整体呈轴对称结构，位于栅格30的一端部的两个第二卡扣304到栅格30的对称轴线的距离不等。In another embodiment of the present invention, one end of the grid 30 is provided with two second buckles 304, and the other end of the grid 30 is provided with at least one second buckle 304, and the valve seat 10 is provided with a separate a first buckle 103 corresponding to the second buckle 304; wherein the grid 30 has an axially symmetric structure as a whole, and the distance between the two second buckles 304 at one end of the grid 30 to the axis of symmetry of the grid 30 is not Wait.

由于蒸汽阀一般设计为左右对称结构，因此安装在阀座10上的栅格30通常设计成与阀座10的形状相适配的左右对称结构，这样在栅格30的装配过程中容易出现栅格30装反的情况，为了避免栅格30装反，在栅格30的一端部设置距栅格30的对称轴线距离不等的两个第二卡扣304，在阀座10上设置与之对应的两个第一卡扣103，实现栅格30装配过程中的防呆效果，解决栅格30装配过程中容易装反的问题。Since the steam valve is generally designed to be a bilaterally symmetrical structure, the grid 30 mounted on the valve seat 10 is generally designed to have a bilaterally symmetrical structure that matches the shape of the valve seat 10, so that the grid is prone to occur during assembly of the grid 30. In the case where the grid 30 is reversed, in order to prevent the grid 30 from being reversed, two second buckles 304 having different distances from the axis of symmetry of the grid 30 are provided at one end of the grid 30, and are disposed on the valve seat 10 Corresponding two first buckles 103 realize the foolproof effect in the assembly process of the grid 30, and solve the problem that the grid 30 is easy to be reversed during the assembly process.

在本发明的又一个实施例中，栅格30的一端部设有一个第二卡扣304，栅格30的另一端部设有至少一个第二卡扣304，阀座10上设有分别与第二卡扣304对应的第一卡扣103；其中，栅格30整体呈轴对称结构，位于栅格30的一端部的第二卡扣304偏离栅格30的对称轴线。In another embodiment of the present invention, one end of the grid 30 is provided with a second buckle 304, and the other end of the grid 30 is provided with at least one second buckle 304, and the valve seat 10 is respectively provided with The first buckle 103 corresponding to the second buckle 304; wherein the grid 30 has an axisymmetric structure as a whole, and the second buckle 304 located at one end of the grid 30 is offset from the axis of symmetry of the grid 30.

由于蒸汽阀一般设计为左右对称结构，因此安装在阀座10上的栅格30通常设计成与阀座10的形状相适配的左右对称结构，这样在栅格30的装配过程中容易出现栅格30装反的情况，为了避免栅格30装反，在栅格30的一端部设置一个第二卡扣304，并使第二卡扣304偏离栅格30的对称轴线设置，在阀座10上设置与之对应的一个第一卡扣103，实现栅格30装配过程中的防呆效果，解决栅格30装配过程中容易装反的问题。Since the steam valve is generally designed to be a bilaterally symmetrical structure, the grid 30 mounted on the valve seat 10 is generally designed to have a bilaterally symmetrical structure that matches the shape of the valve seat 10, so that the grid is prone to occur during assembly of the grid 30. In the case where the grid 30 is reversed, in order to prevent the grid 30 from being reversed, a second buckle 304 is disposed at one end of the grid 30, and the second buckle 304 is disposed away from the axis of symmetry of the grid 30, at the valve seat 10 A first buckle 103 corresponding thereto is disposed thereon to realize the foolproof effect during assembly of the grid 30, and solve the problem that the grid 30 is easy to be reversed during the assembly process.

在本发明的一个实施例中，如图1所示，阀座10上开设有进汽口101，阀盖20上开设有出汽口203，栅格30包括多个环绕进汽口101的挡筋301，相邻挡筋301之间围设出蒸汽通道302，挡筋301上设有连通相邻蒸汽通道302的栅格缺口(图中未示出)。In an embodiment of the present invention, as shown in FIG. 1, the valve seat 10 is provided with an inlet port 101, and the valve cover 20 is provided with a steam outlet 203. The grid 30 includes a plurality of blocks surrounding the inlet port 101. A rib 301, a steam passage 302 is disposed between the adjacent ribs 301, and a rib (not shown) communicating with the adjacent steam passages 302 is disposed on the ribs 301.

栅格30包括多个环绕进汽口101的挡筋301，相邻两个挡筋301之间围设出蒸汽通道302，相邻两个蒸汽通道302通过设在挡筋301上的栅格缺口相连通，以增长蒸汽进入蒸汽腔后在蒸汽腔内的流动距离，达到良好的脱泡效果，并使蒸汽中夹杂的米粒、粥汤等能够与蒸汽充分分离、并回落至蒸汽腔内，从而达到良好的防溢出效果。The grid 30 includes a plurality of ribs 301 surrounding the inlet port 101, and a space between two adjacent ribs 301 a steam passage 302 is provided, and two adjacent steam passages 302 are communicated through a grid notch provided on the retaining rib 301 to increase the flow distance of the steam into the steam chamber and to achieve a good defoaming effect, and The rice grains, porridge soup and the like which are mixed in the steam can be sufficiently separated from the steam and fall back into the steam chamber, thereby achieving a good anti-overflow effect.

在上述实施例中，优选地，如图1和图2所示，相邻挡筋301之间的间隙宽度不小于7mm，以保证成人手指能够伸入相邻两个挡筋301之间，对挡筋301内的杂物进行清洗，从而解决栅格3030难清洗完全的问题。In the above embodiment, preferably, as shown in FIG. 1 and FIG. 2, the gap width between the adjacent retaining ribs 301 is not less than 7 mm to ensure that the adult fingers can extend between the adjacent two retaining ribs 301, The debris in the retaining rib 301 is cleaned, thereby solving the problem that the grid 3030 is difficult to clean completely.

在上述实施例中，优选地，如图1和图2所示，相邻挡筋301之间的间隙宽度不大于10mm，这样在相同大小的空间内，可有效增加挡筋301的数量，进而增加挡筋301所围设出的蒸汽通道302的数量，从而进一步增长蒸汽在蒸汽通道302内的流动距离，达到良好的脱泡及防溢出效果。In the above embodiment, preferably, as shown in FIG. 1 and FIG. 2, the gap width between the adjacent retaining ribs 301 is not more than 10 mm, so that the number of the retaining ribs 301 can be effectively increased in the same size space. The number of steam passages 302 surrounded by the retaining ribs 301 is increased to further increase the flow distance of the steam in the steam passages 302 to achieve good defoaming and anti-spilling effects.

优选地，如图2所示，将相邻挡筋301之间的间隙宽度控制在7mm～10mm的范围内，既解决了栅格30难清洗完全的问题，又保证了蒸汽阀具有良好的防溢出效果。当然，相邻挡筋301之间的间隙不限于上述具体范围的限定，可根据实际情况进行合理调整，只要不脱离本发明的设计构思，均应在本发明的保护范围内。Preferably, as shown in FIG. 2, the gap width between the adjacent retaining ribs 301 is controlled within a range of 7 mm to 10 mm, which not only solves the problem that the grid 30 is difficult to clean completely, but also ensures that the steam valve has good protection. Overflow effect. Of course, the gap between the adjacent retaining ribs 301 is not limited to the above specific range, and can be reasonably adjusted according to the actual situation, as long as it does not deviate from the design concept of the present invention, and should be within the protection scope of the present invention.

在上述实施例中，优选地，挡筋301的厚度为1mm～2mm，既能保证栅格30的强度，又不影响栅格30的可变形度。In the above embodiment, preferably, the thickness of the retaining rib 301 is 1 mm to 2 mm, which can ensure the strength of the grid 30 without affecting the deformability of the grid 30.

进一步地，如图1和图2所示，相邻挡筋301之间连接有连接筋303，连接筋303的竖直高度小于挡筋301的竖直高度；或，连接筋303上开设有供蒸汽通过的通汽孔(图中未示出)。Further, as shown in FIG. 1 and FIG. 2, connecting ribs 303 are connected between the adjacent retaining ribs 301, and the vertical height of the connecting ribs 303 is smaller than the vertical height of the retaining ribs 301; or, the connecting ribs 303 are opened for A steam passage through which steam passes (not shown).

在相邻挡筋301之间连接有连接筋303，以增强栅格30的整体结构强度；连接筋303的竖直高度小于挡筋301的竖直高度，或，连接筋303上开设有供蒸汽通过的通汽孔，保证连接筋303的设置不会影响蒸汽在相邻挡筋301之间围设出的蒸汽通道302内流动。Connecting ribs 303 are connected between adjacent retaining ribs 301 to enhance the overall structural strength of the grid 30; the vertical height of the connecting ribs 303 is smaller than the vertical height of the retaining ribs 301, or the connecting ribs 303 are provided with steam for opening The passing steam holes ensure that the arrangement of the connecting ribs 303 does not affect the flow of steam in the steam passages 302 enclosed between the adjacent retaining ribs 301.

在本发明的一个实施例中，如图6所示，阀盖20的顶壁的内壁面上设有多个加强筋201，加强筋201的形状与蒸汽通道302的形状相适配，相邻加强筋201之间限定出下端开口的限位凹槽202，挡筋301的上端部限位在限位凹槽202内。 In an embodiment of the present invention, as shown in FIG. 6, a plurality of reinforcing ribs 201 are disposed on the inner wall surface of the top wall of the valve cover 20, and the shape of the reinforcing rib 201 is adapted to the shape of the steam passage 302, adjacent to each other. A limiting recess 202 is defined between the reinforcing ribs 201 to define a lower end opening. The upper end of the retaining rib 301 is limited to the limiting recess 202.

通过在蒸汽阀的阀盖20上增设加强筋201，有效增强阀盖20的强度，防止阀盖20在工作过程中因温度过高而变形，尤其对于尺寸相对较大的蒸汽阀，随着阀盖20的尺寸增大会导致阀盖20的强度降低、易受热变形，通过在阀盖20上设置加强筋201，防止阀盖20受热变形的效果更明显；将挡筋301的上端部限位在相邻加强筋201之间限定出的限位凹槽202内，达到固定栅格30的作用，解决栅格30在蒸汽腔内固定不牢、易活动的问题。By adding a reinforcing rib 201 to the valve cover 20 of the steam valve, the strength of the valve cover 20 is effectively enhanced, and the valve cover 20 is prevented from being deformed due to excessive temperature during operation, especially for a relatively large-sized steam valve, along with the valve. The increase in the size of the cover 20 causes the strength of the valve cover 20 to be lowered and is susceptible to thermal deformation. By providing the rib 201 on the valve cover 20, the effect of preventing the bonnet 20 from being thermally deformed is more conspicuous; the upper end portion of the rib 301 is limited to The fixing groove 30 defined between the adjacent reinforcing ribs 201 reaches the role of the fixed grid 30, and solves the problem that the grid 30 is not firmly fixed in the steam chamber and is easy to move.

实施例二：Embodiment 2:

如图1和图6所示，根据本发明一些实施例提供的一种蒸汽阀，包括：阀座10和阀盖20。As shown in FIGS. 1 and 6, a steam valve according to some embodiments of the present invention includes a valve seat 10 and a valve cover 20.

其中，阀盖20盖设在阀座10上，并与阀座10相连接围成蒸汽腔，阀盖20的顶壁上设有加强筋201。The valve cover 20 is disposed on the valve seat 10 and connected to the valve seat 10 to form a steam chamber. The top wall of the valve cover 20 is provided with a reinforcing rib 201.

本发明上述实施例提供的蒸汽阀，通过在蒸汽阀的阀盖20上增加加强筋201，有效增强阀盖20的强度，防止阀盖20在工作过程中因温度过高而变形，尤其对于尺寸相对较大的蒸汽阀，随着阀盖20的尺寸增大会导致阀盖20的强度降低，通过在阀盖20上设置加强筋201，防止阀盖20受热变形的效果更明显。The steam valve provided by the above embodiment of the present invention effectively increases the strength of the valve cover 20 by adding a reinforcing rib 201 to the valve cover 20 of the steam valve, thereby preventing the valve cover 20 from being deformed due to excessive temperature during operation, especially for the size. With a relatively large steam valve, as the size of the valve cover 20 increases, the strength of the valve cover 20 is lowered. By providing the rib 201 on the valve cover 20, the effect of preventing the bonnet 20 from being thermally deformed is more remarkable.

在本发明的一个实施例中，如图1和图6所示，加强筋201为阀盖20的顶壁的外壁面向下凹陷形成。In one embodiment of the present invention, as shown in FIGS. 1 and 6, the reinforcing rib 201 is formed such that the outer wall of the top wall of the valve cover 20 is recessed downward.

The structure is simple and the processing is convenient.

在本发明的另一个实施例中，加强筋201为阀盖20的顶壁的内壁面向下凸出形成。In another embodiment of the present invention, the reinforcing rib 201 is formed such that the inner wall of the top wall of the valve cover 20 is convex downward.

为了提高阀盖20的结构强度，在阀盖20的顶壁的内壁面上直接设置向下凸出的凸筋，同样能够达到提升阀盖20的结构强度的目的。In order to increase the structural strength of the valve cover 20, the downwardly projecting ribs are directly provided on the inner wall surface of the top wall of the valve cover 20, and the structural strength of the bonnet 20 can be improved.
