Abstract

本实用新型公开了一种新型控制球阀，包括执行器、方形阀门轴头、阀球、配流盘，所述的方形阀门轴头连接执行器，配流盘与阀球连接，配流盘的内侧为凹形，与阀球紧密配合，水流通过阀芯开孔与配流盘V型开口之间的开度得到精确控制。通过配流盘，球阀的Kvs值减小到形同规格座阀的Kvs值。安装不同形状开口的配流盘，同一尺寸的阀门还可有不同的Kvs，避免了水管变径的麻烦。

Description

一种新型控制球阀 
技术领域
本实用新型涉及一种球阀，尤其是涉及一种在球阀的入口处增加配流盘，使其流量特性转变成等百分比特性的一种新型控制球阀。 
背景技术
已有技术的控制球阀，流量激增过快；流量系数过大；流量控制部分负载，造成这种现象的原因是由于传统球阀在阀门刚刚开启时，流量增加过快，即呈现快开特性。同时传统球阀的流量系数值很大，数倍于相同公称直径的座阀。 
发明内容
本实用新型的目的在于克服现有技术之不足，提供一种新型控制球阀。本实用新型结构简单，成本低，具有更好的控制力。 
实现本实用新型发明目的的技术方案如下： 
一种新型控制球阀，包括执行器、方形阀门轴头、阀球、配流盘，所述的方形阀门轴头连接执行器，配流盘与阀球连接，配流盘的内侧为凹形，与阀球紧密配合，水流通过阀芯开孔与配流盘V型开口之间的开度得到精确控制。通过配流盘，球阀的Kvs值减小到形同规格座阀的Kvs 值。安装不同形状开口的配流盘，同一尺寸的阀门还可有不同的Kvs，避免了水管变径的麻烦。 
附图说明
图1为本实用新型结构示意图 
图中标号说明： 
1-执行器 
2-方形阀门轴头 
3-阀球 
4-配流盘 
5-内螺纹 
具体实施方式 
下面结合附图进一步说明本实用新型是如何实现的： 
如图1所示，一种新型控制球阀，包括执行器、方形阀门轴头、阀球、配流盘、内螺纹，所述的方形阀门轴头2连接执行器1，配流盘4与阀球3连接，内螺纹5连接法兰，配流盘4的内侧设为凹形，与阀球3紧密配合，水流通过阀芯开孔与配流盘V型开口之间的开度得到精确控制。通过配流盘4，球阀的Kvs值减小到形同规格座阀的Kvs值。安装不同形状开口的配流盘，同一尺寸的阀门还可有不同的Kvs，避免了水管变径的麻烦。
