Abstract

本实用新型提供一种阀,它是在原“全封闭无泄 漏胶控水龙头”专利的基础上,将开关部件阀芯改成 连体式的全封闭无泄漏阀。改进的开关部件阀芯由 旋钮螺杆3、“干”字形圆连体螺杆5穿过倒扣圆胶碗 6、活塞块7、密封片10中心连成一体构成。
经改进后本阀,加工易,性能更可靠,适用各种流 体介质范围广。

Description

本实用新型涉及各种流体介质的控制阀,特别是全封闭无泄漏阀(水龙头)。它是在“ZL90220701.6全封闭无泄漏胶控水龙头”专利的基础上,加以改进而成,经此改进,更适于各种液、气、油等流体介质中应用。
原我们设计的“全封闭无泄漏胶控水龙头”专利,虽适于无粘性的流体用,无泄漏,但用于含粘性的液、油、蒸汽时,开关部件会有被粘性流体介质粘着,而使控制启闭不够灵活,影响正常使用。
本实用新型的任务,所提供的是在“全封闭无泄漏胶控水龙头”专利的基础上,加以改进,将开关部件改成连体式的全封闭无泄漏阀,解决了上述的粘着问题,保持原“全封闭无泄漏胶控水龙头”的优点,适用范围广、更可靠。
其任务由下面给出的附图结构实现:
图1是本实用新型的开状态结构示意图,图中:1、螺钉,2、手柄,3、旋钮螺杆,4、阀体盖,5、“干”字形圆连体螺杆,6、倒扣圆胶碗,7、活塞块,8、阀体,9、螺母,10、密封片,11、限定提升螺钉;
其开关部件改进的结构如图1所示:旋钮螺杆3上端用螺钉1固定手柄2,下端内径两侧有限定提升螺钉11,“干”字形圆连体螺杆5穿过倒扣圆胶碗6、活塞块7、密封片10中心,“干”字上端一短横套入旋钮螺杆3下端内径中,以螺钉11卡住限定作辅助提升作用,“干”字一长横抵住倒扣圆胶碗底伸出的短凸柱圈,连体螺杆5下端有螺纹与活塞块7接合,活塞块上凸出部分套在倒扣圆胶碗中伸出的长凸柱圈上,密封片10嵌入活塞块下的凹面,并用螺母9紧固而连成一体;倒扣圆胶碗周边装在阀体8与阀体盖4空隙之间,沿其周边外弧面一部分与阀体盖内壁弧面一致,这样,保持密封性好,又增强倒扣圆胶碗的启闭能力。
按上述设计的全封闭无泄漏阀,也可设计成水龙头,在广西南宁化学工业集团公司试用,时间四个多月,使用流体介质是三酸二碱,结果:启闭灵活轻巧,性能可靠,无跑、冒、滴、漏现象,耐酸、碱、油、热,不污染环境,价格低,经济效益显著,深受公司工程技术人员和工人的一致好评。
本阀根据用于不同的流体介质,其开关部件阀芯采用不同的质材即可。
