Abstract

本实用新型是一种采用弹性波纹密封胶杯为隔 膜的全封闭无泄漏截止阀，由阀体(5)、旋动手轮(1)、 旋杆(2)、压盖(5)及密封胶杯(4)等构成。通过调节 密封胶杯(4)底平面与阀体(5)液(汽)体进口平面的 间隙，实现阀的导通关闭。由于密封胶杯(4)上缘被 压盖(3)紧压扣于阀体(5)上缘，阀内流通的液(汽)体 不能上冒泄漏。本实用新型结构简单，使用可靠，适 合装配在所有不允许液(汽)体泄漏的设备上使用。

Description

本实用新型涉及阀门，尤其是一种采用弹性波纹密封胶杯为隔膜的全封闭无泄漏截止阀。
在专利号为90220701的“全封闭无泄漏截止阀水龙头”专利文件中，向公众公开了一种能实现无泄漏的全封闭截止阀。但由于其仍存在着组成零件多，制造成本高的缺点，并因其操作间接部件多而直接影响产品的功能和耐用性。
本实用新型的目的在于提供一种结构简单，使用可靠，只由五个零件构成的全封闭无泄漏截止阀。
本实用新型的全封闭无泄漏截止阀包括阀体、旋动手轮、旋杆、压盖及弹性波纹密封杯等构成。
下面结合附图对本实用新型作进一步的说明。
图1是本实用新型的结构示意图。
如图1所示，本实用新型的全封闭无泄漏截止阀包括导流液（汽）体的阀体（5）；插入阀体（5）内，调节导通或关闭程度状态的旋杆（2）；嵌扣于旋杆（2）上端，正反向旋动旋杆（2）的旋动手轮（1）；置于阀体（5）内，上边缘搭扣于阀体（5）内腔上缘，内腔容纳插入的旋杆（2），底部外侧平盖于阀体（5）内腔进口端平面上的喉管状弹性波纹密封胶杯（4）；内圈螺纹与旋杆（2）外螺纹啮合，并将密封胶杯（4）上边缘扣压于阀体（5）内腔上缘的通孔压盖（3）等构成。
当顺时针旋动手轮（1），随手轮（1）转动的旋杆（2）通过固定的压盖（3）内螺纹作用而向下落，旋杆（2）下端面将密封胶杯（4）紧紧扣盖在阀体（5）液（汽）体进口端平面上，截断流通。当反时针旋动手轮（1）时，旋杆（2）随之上升。受流通液（汽）体压力作用，密封胶杯（4）底平面与阀体（5）液（汽）体进口端平面间隙逐渐打开，实现导通和流量调节的目的。由于密封胶杯（4）上缘被压盖（3）紧压扣于阀体（5）上缘，阀体内流通的液（汽）体不能上冒泄漏。密封胶杯（4）可采用橡胶、塑料、乃至金属等材料制成。
本实用新型的全封闭无泄漏截止阀具有结构简单，组成零件少，加工精度要求低，使用可靠等优点，适合装配在所有不允许液（汽）体泄漏的设备上使用。
