Description

流量调节阀 技术领域
本申请涉及流量调节阀技术领域,具体而言,涉及一种流量调节阀。
背景技术
在流量调节阀中,通过阀头在阀体内的移动来打开或关闭阀口。现有技术中,通常是阀头端部的周缘和阀口的内壁接触形成密封面,从而实现密封以关闭阀口。但阀头和阀体都是金属结构,在关闭阀口时两者硬接触,导致接触面积小,密封性较差。
发明内容
本申请提供了一种流量调节阀,以提高流量调节阀的密封性。
为了实现上述目的,本申请提供了一种流量调节阀,包括:阀体结构,所述阀体结构包括主体和与所述主体连接的密封座,所述密封座具有阀口,所述密封座由非金属材料制成;阀头,可移动地设置在所述主体的腔体内,以关闭或打开所述阀口,所述阀头由金属材料制成,所述密封座的硬度小于所述阀头的硬度。
采用该方案,由于密封座由硬度比阀头小的非金属材料制成,在关闭阀口时,阀头和密封座接触,密封座产生弹性变形,这样密封座和阀头接触面积大,从而提高了阀口的密封效果。
进一步地,所述密封座由塑料制成。采用塑料材质,密封座弹性变形量大,从而可提高密封效果,并且制造成本低。
进一步地,所述主体包括相互连接的阀座和筒体,所述阀座和所述筒体之间具有安装腔,所述密封座的一部分位于所述安装腔内。通过上述设置,便于密封座的布置和安装。
进一步地,所述阀座的内侧具有第一限位台阶,所述密封座的一端具有第二限位台阶,所述第二限位台阶和所述第一限位台阶抵接;所述密封座的另一端和所述筒体抵接。这样通过第一限位台阶和第二限位台阶的配合,可对密封座进行精确定位和限位。
进一步地,所述阀座的外侧具有第一配合台阶,所述筒体具有第二配合台阶,所述第二配合台阶和所述第一配合台阶配合。通过第二配合台阶和第一配合台阶的配合,实现了阀座和筒体的精确定位,从而便于两者的装配和连接。
进一步地,所述筒体和所述阀座均为金属材料,所述筒体和所述阀座焊接固定并夹持所述密封座。具体地,可采用激光焊接。采用焊接的方式,连接牢固,可靠性好。
进一步地,所述流量调节阀还包括:第一阀管,所述第一阀管和所述阀座连接;第二阀管,所述第二阀管和所述筒体连接。通过第一阀管和第二阀管可实现流量调节阀和其他管路的连接。阀口打开后,第一阀管和第二阀管连通。
进一步地,所述阀口的内壁具有锥形面。通过锥形面和阀头的配合,便于进行流量调节。
进一步地,所述流量调节阀还包括:导向套,设置在所述主体的腔体内,所述阀头可移动地设置在所述导向套内;驱动部,所述驱动部和所述阀头驱动连接,以驱动所述阀头移动。导向套用于对阀头进行导向。驱动部可采用电磁驱动的方式。
进一步地,所述流量调节阀为电子膨胀阀。
应用本申请的技术方案,提供了一种流量调节阀,流量调节阀包括阀体结构和阀头,阀体结构包括主体和与主体连接的密封座,密封座具有阀口,密封座由非金属材料制成;阀头可移动地设置在主体的腔体内,以关闭或打开阀口,阀头由金属材料制成,密封座的硬度小于阀头的硬度。采用该方案,由于密封座由硬度比阀头小的非金属材料制成,在关闭阀口时,阀头和密封座接触,密封座产生弹性变形,这样密封座和阀头接触面积大,从而提高了阀口的密封效果。
