Description

主阀座及四通阀 技术领域
本申请涉及四通阀技术领域，具体而言，涉及一种主阀座及四通阀。
背景技术
对于现有技术中的四通阀的主阀座，第一直边、第二直边和底边所成内角的角度大于等于90度，这样设置，导致底边长度较短，降低了主阀座材料的利用率，增加了加工成本，而且由于主阀座上其他尺寸的限定要求，使得主阀座的第一直边、第二直边不能再被二次加工，使主阀座的适用范围受限。
申请内容
本申请提供了一种主阀座及四通阀，以提高主阀座材料的利用率，降低加工成本。
为了实现上述目的，根据本申请的一个方面，本申请提供了一种主阀座，在主阀座的径向截面上，主阀座包括第一直边、圆弧边、第二直边和底边，圆弧边的两端分别和第一直边、第二直边的一端连接，底边的两端分别和第一直边、第二直边的另一端连接，第一直边和第二直边位于圆弧边所在的圆内，其中，第一直边和底边之间内角为α、第二直边和底边之间的内角为β，α＜90°，β＜90°。
进一步地，主阀座沿预设方向延伸，主阀座的端面垂直于预设方向，主阀座沿预设方向间隔设置有多个安装孔，安装孔包括相互连通的第一孔段和第二孔段，第一孔段和第二孔段同轴设置，第一孔段的径向尺寸为D1，第二孔段的径向尺寸为D2，D2＞D1。
进一步地，底边的长度为A，D1+4≥1.5D1时，A≥D1+4；D1+4<1.5D1时，A＝((D1+4)～1.5D1)mm。
进一步地，底边的长度为A，圆弧边距底边的最大距离为H，圆弧边的半径为R，(2R-D1-2)mm≤H≤(2R-D1-9)mm，R＝√((A/2)^2+(R-H)^2)。
进一步地，圆弧边距底边的最大距离为H，圆弧边的半径为R，第二孔段的深度为h，(D2-D1)/2＝t，h＝H-1.5-√(R^2+(D2/2)^2)，h>3t。
进一步地，在垂直于预设方向且过安装孔的轴线的截面上，第一直边和第二直边相对于安装孔的轴线对称设置，安装孔和圆弧边的其中一个交点为E点，E点和第一直边位于安装孔轴线同一侧，圆弧边位于E和第一直边之间的弧线的长度为L，2mm≤L≤5mm。
进一步地，α＝β，第一直边的长度等于第二直边的长度。
进一步地，第一直边、第二直边和底边的连接处均具有倒角。
根据本申请的另一方面，提供了一种四通阀，四通阀包括阀套和上述的主阀座，主阀座设置在阀套内。
进一步地，在阀套的径向截面上，第一直边和阀套的内壁之间的区域为第一储料区，第二直边和阀套的内壁之间的区域为第二储料区，第一储料区和第二储料区用于储存焊料。
应用本申请的技术方案，提供了一种主阀座，在主阀座的径向截面上，主阀座包括第一直边、圆弧边、第二直边和底边，圆弧边的两端分别和第一直边、第二直边的一端连接，底边的两端分别和第一直边、第二直边的另一端连接，第一直边和第二直边位于圆弧边所在的圆内，其中，第一直边和底边之间内角为α、第二直边和底边之间的内角为β，α＜90°，β＜90°。采用该方案，在主阀座的其他尺寸，如主阀座的高度、圆弧边的半径和长度相同的前提下，本方案中的限定内角α＜90°、β＜90°与现有技术中的内角α、内角β均≥90°相比，本方案的设置方式增加了底边的长度，进而提高了主阀座的材料的利用率，降低了加工成本。而且这样设置，可以先使主阀座的内角α和内角β的角度取值较大，之后在根据实际情况对第一直边和第二直边进行二次加工，从而减小对应的内角α和内角β的角度取值，增加主阀座的可调性。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何 限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1至图6所示，本申请的实施例提供了一种主阀座，在主阀座10的径向截面上，主阀座10包括第一直边11、圆弧边12、第二直边13和底边14，圆弧边12的两端分别和第一直边11、第二直边13的一端连接，底边14的两端分别和第一直边11、第二直边13的另一端连接，第一直边11和第二直边13位于圆弧边12所在的圆内，其中，第一直边11和底边14之间内角为α、第二直边13和底边14之间的内角为β，α＜90°，β＜90°。
在本实施例中，在主阀座10的其他尺寸，如主阀座10的高度、圆弧边12的半径和长度相同等前提下，本方案中的限定内角α＜90°、β＜90°与现有技术中的内角α、内角β均≥90°相比，本方案的设置方式增加了底边14的长度，进而提高了主阀座10的材料的利用率，降低了加工成本。而且这样设置，可以先使主阀座10的内角α和内角β的角度取值较大，之后在根据实际情况分别对第一直边11和第二直边13进行二次加工，从而减小对应的内角α和内角β的角度取值，增加主阀座10的可调性。
如图1和图2所示，主阀座10沿预设方向20延伸，主阀座10的端面垂直于预设方向20，主阀座10沿预设方向20间隔设置有多个安装孔15，安装孔15包括相互连通的第一孔段151和第二孔段152，第一孔段151和第二孔段152同轴设置，第一孔段151的径向尺寸为D1，第二孔段152的径向尺寸为D2，D2＞D1。这样设置，通过第一孔段151和第二孔段152之间的台阶来对***主阀座10内的外接管进行限位，保证主阀座10和外接管连接的可靠性。
具体地，底边14的长度为A，D1+4≥1.5D1时，A≥D1+4；D1+4<1.5D1时，A＝((D1+4)～1.5D1)mm。这样设置，保证在垂直于预设方向20且过安装孔15的轴线的截面上，第一孔段151的最大开口尺寸，即D1和底边14的长度A之间始终有一个安全差值，以保证第二孔段152的最大开口尺寸D2不会过大而导致最大开口两端的两侧的圆弧边12过短，进而影响主阀座10的密封性。
进一步地，底边14的长度为A，圆弧边12距底边14的最大距离为H，圆弧边12的半径为R，(2R-D1-2)mm≤H≤(2R-D1-9)mm，R＝√((A/2)^2+(R-H)^2)。这样设置，对R、H、A和D1之间的关进行界定，使R、H、A和D1之间能够相互限制，保证了主阀座的可靠性。
进一步地，圆弧边12距底边14的最大距离为H，圆弧边12的半径为R，第二孔段152的深度为h，(D2-D1)/2＝t，h＝H-1.5-√(R^2+(D2/2)^2)，h>3t。这样设置，通过对第二孔段152深度h的限定，进一步防止了第二孔段152的最大开口位置两端的两侧剩余的圆弧边12过短，保证了主阀座10的密封性和可靠性。而且通过对h的限定，对H、R、D2、t等尺寸作出了进一步限定，保证主阀座10的可靠性。
进一步地，如图2所示，在垂直于预设方向20且过安装孔15的轴线的截面上，第一直边11和第二直边13相对于安装孔15的轴线对称设置，安装孔15和圆弧边12的其中一个交 点为E点，E点和第一直边11位于安装孔15轴线同一侧，圆弧边12位于E和第一直边11之间的弧线的长度为L，2mm≤L≤5mm。
在本实施例中，L即为，在垂直于预设方向20且过安装孔15的轴线的截面上，第二孔段152的最大开口位置的两端两侧剩余的圆弧边12的弧长，通过对L进行限定，能进一步保证主阀座10的密封性，同时通过对L的限定，间接地对主阀座10其他尺寸，如H、R、A、h等尺寸作出了进一步限定，保证主阀座10的可靠性。
在本实施例中，α＝β，第一直边11的长度等于第二直边13的长度。这样设置，使α＝β，同时由于第一直边11的长度和第二直边13的长度相等，使得与第一直边11、第二直边13连接的圆弧边12也为对称结构，进而保证主阀座10整体为对称结构，便于加工，降低了加工成本。
具体地，第一直边11、第二直边13和底边14的连接处均具有倒角。通过设置倒角，去除加工成型的主阀座10的边沿的毛刺，同时便于零件的装配，其中，两侧的倒角相同，便于加工，降低加工成本。
具体地，底边的长度A为第一直边11远离圆弧边12的一端、第二直边13远离圆弧边12的一端的距离和削去的在底边延长线上的两个倒角的长度和之间的差值。
本申请的另一实施例提供了一种四通阀，四通阀包括阀套30和上述的主阀座10，主阀座10设置在阀套30内。其中，主阀座10的圆弧边12延伸形成的圆弧面和阀套30的内侧壁限位配合。具体地，阀套30和主阀座10之间的连接为焊接，连接可靠，连接方式简单。
如图6所示，在阀套30的径向截面上，第一直边11和阀套30的内壁之间的区域为第一储料区41，第二直边13和阀套30的内壁之间的区域为第二储料区42，第一储料区41和第二储料区42用于储存焊料。这样设置，通过第一储料区41和第二储料区42来储存焊料，保证焊接位置能够容纳足够的焊料，保证焊接的稳定性和质量，同时还能防止焊料进入阀套的腔体内从而影响内部其他零部件之间的配合，保证四通阀的可靠性。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
