Abstract

一种截止阀、上盖与阀体之间装有弧形密封橡胶垫,螺杆的下端面为弧面,阀体内设有隔板,密封橡胶垫与隔板充分吻合,所以截止效果好,实用性强。

Description

截止阀
本实用新型涉及一种供水管路终端控制水流的阀。
目前,市场使用的截止阀普遍使用球阀、闸阀,制动部分在液气体状态中截放,机械吻合精密,都无法阻挡高压下的液、气体的穿射,同时,随着使用周期增长,机械磨损增加,吻合度差,因而造成跑、冒、滴、漏现象严重,浪费宝贵资源。
本实用新型的目的是提供一种密封性好的截止阀。
本实用新型的目的是这样实现的:该截止阀包括阀体、上盖、螺杆,上盖与阀体之间装有弧形密封橡胶垫,紧杆头的下端面为弧形,阀体内设有隔板。
由于弧形密封垫将上盖完全密封,阻止水从上盖渗漏,且弧形密封垫与隔板充分吻合,截止效果好。
图1为本实用新型结构剖视图;
图2为阀体6的A-A剖视图。
下面结合附图和实施例对本实用新型作进一步描述。
如图1所示,螺杆1安装在上盖2内,螺杆3与上盖2之间用铜套3密封,密封橡胶垫5固定在上盖3与阀体6之间,螺杆2的下端面为弧形。如图2所示,隔板7为“U”型,当螺杆1向前推进时,推动密封挍胶垫5弧面向下移动,直至与隔板7的“U”型面相吻合,来达到截止目的;反之,螺杆1向上移动,密封橡胶垫5自身的弹性,弧面向上移动,与隔板7的“U”型面分离,使阀体6开通。
