Description

可调节定量取样阀
技术领域
本发明属于阀门领域，尤其涉及一种取样阀。本发明适用于抗生素等生物制药管道介质的在线定量取样装置。
背景技术
取样阀安装于介质输送管道上实现对介质的取样、检测、分析，在线取样阀是直接将取样阀体安装于介质输送管道上，在介质输送管道正常流体的情况下，对管道内介质进行取样。现有取样阀的阀体与介质管道之间存在残留死角，不易清洗，对批间介质产生污染，而且取样的定量精度差。
发明内容
本发明的目的是针对现有技术存在的缺点，提供一种清洗容易、批间污染少、可定量取样的可调节定量取样阀。
本发明的技术方案包括阀体、阀芯、阀杆，阀芯外圆柱面与阀体通道内壁动密封配合构成柱塞式结构，阀体水平安装于介质管道一侧，取样口设置在阀体下侧，阀芯一端与阀杆固定连接，阀杆通过阀杆螺母与手轮连接；主要是阀芯另一端制有与介质管道通孔相同弧度的圆弧面，在取样阀全关状态时，阀芯端部的圆弧面与介质管道通孔构成完整的圆孔；阀芯中心制有定量取样装置，该定量取样装置由阀芯取样孔、活塞和活塞杆组成，活塞外圆面与阀芯取样孔动密封配合，活塞杆的一端与活塞端面中心连接，活塞杆的另一端制有取样标尺，在取样标尺内侧的活塞杆外圆面与阀杆中心孔之间螺纹配合，活塞杆与阀杆端面之间由锁紧螺母固定；阀芯取样孔连通径向进料口和径向出料口，在取样阀全关状态时，径向出料口与取样口对齐，径向进料口与阀体通道内壁密封配合；在取样阀全开状态时，径向进料口与介质管道通孔连通，径向出料口与阀体通道内壁密封配合。
本发明的优点是阀芯端部与介质管道通孔相同弧度的圆弧面，在取样阀全关状态时，阀芯端部的圆弧面与介质管道通孔构成完整的圆孔，防止介质积留造成样品污染；阀芯中心制有定量取样装置，调节定量取样装置中活塞在阀芯取样孔内的位置，设定取样数量，实现可调节定量取样。
附图说明
图1是本发明取样状态的结构示意图。
图2是本发明全关状态的结构示意图。
具体实施方式
如图1所示的可调节定量取样阀，包括阀体1、阀芯2、阀杆3，阀芯2外圆柱面与阀体1通道内壁动密封配合构成柱塞式结构，阀体1水平安装于介质管道4一侧，取样口5设置在阀体下侧，阀芯2一端与阀杆3固定连接，阀杆3通过阀杆螺母6与手轮7连接，阀杆螺母6由轴承安装在支架内，支架与阀杆3设置防转装置；阀芯2另一端制有与介质管道4通孔相同弧度的圆弧面，在取样阀全关状态时，阀芯2端部的圆弧面与介质管道4通孔构成完整的圆孔，清洗容易，较小污染；阀芯2中心制有定量取样装置，该定量取样装置由阀芯取样孔8、活塞9和活塞杆10组成，活塞9外圆面与阀芯取样孔8动密封配合，活塞杆10的一端与活塞9端面中心连接，活塞杆10的另一端制有取样标尺11，该取样标尺11的刻度显示取样数量，在取样标尺11内侧的活塞杆10外圆面与阀杆3中心孔之间螺纹配合，使取样标尺11在阀杆3中心孔可移动，调节活塞9在阀芯取样孔8内的位置，实现对取样样品数量的调节，活塞杆10与阀杆3端面之间由锁紧螺母12固定，锁定取样样品数量的设定值；阀芯取样孔8连通径向进料口13和径向出料口14；在取样阀全开状态时，径向进料口13与介质管道4通孔连通，径向出料口14与阀体1通道内壁密封配合；在取样阀全关状态时，径向出料口14与取样口5对齐，径向进料口13与阀体1通道内壁密封配合，如图2所示。取样时，打开取样阀，使其径向进料口13与介质管道4通孔连通，介质进入阀芯取样孔8内，关闭取样阀即可将阀芯取样孔8内的介质通过取样口5装入取样容器，完成取样操作。
