Abstract

本发明涉及一种管道配件,特别是介质为液体的阀门。目前的阀门推进装置——螺纹完全或部分埋进液体内。易受侵蚀,而阀门一旦咬牙烂牙,就不能开闭,不打开盖就无法排故。本发明提供一种螺纹避开液体,发生故障可用应急开关开闭,不打开盖即可迅速检修的阀门。提高了使用可靠性、安全性,避免不必要损失,延长了使用寿命。

Description

螺纹可整体移动的阀
本发明涉及一种管道配件,特别是介质为液体的阀门。目前所有的阀门,其推进装置——螺纹完全或部分埋进液体内。易受侵蚀,发生咬牙烂牙就不能开闭,不打开阀盖就无法修理。
为解决这个问题通常的做法,是定期试试。如消防拴、自来水的总阀……但即使试过了,到用时还有打不开、关不死造成不必要的损失。
本发明提供一种不同结构的阀,螺纹避开液体,发生故障可用应急开关开闭又可不打开盖排故,延长了阀的寿命,提高了使用可靠性、安全性。
本发明是这样实现的:将密闭圈设置在螺纹前,使螺纹与介质分开。将与阀盖一体的螺母或螺杆与盖分开。用锁定帽,紧固在阀盖上。发生咬牙烂牙情况时,螺纹失去推进功能了。旋转锁定帽,就会牵动螺母或螺杆与阀盖分离、整体与盖作相对运动,牵动阀门开闭。如将锁定帽打开,便可检修。将螺母分开二半检修更方便。
本发明因为只改动了螺纹结构,所以不复杂。因为螺纹避开了液体,所以延长了阀使用寿命,因为发生故障照样可开闭,又可以在使用状态下打开阀盖修理,所以提高了使用可靠性、安全性。
本发明的具体结构,由以下的实施例及其附图给出
图1是根据本发明提出的,螺纹可整体移动的阀。
下面结合图1,详细说明。依据本发明提出的具体结构及工作情况。
该装置包括被锁紧帽(1);紧锁在阀盖(2)上的螺母(3)、被螺母(3)夹在中间的螺杆(4)。当螺纹失去推进功能时,旋动锁定帽(1),螺母(3)与螺杆(4)整体相对与阀盖(3)作运动,开闭阀门。当打开锁紧帽(1),螺母(3)即与阀盖(2)分开。螺母(3)与螺杆(4)松开。接受检修。
如结构以螺杆代替螺母作用。比如闸阀,则螺母(3)与螺杆(4)合为螺杆(4)。阀门(5)改成为螺母(3)工作情况一样,略。

Claims (2)

1)本发明涉及介质为液体的阀门,其特征在于螺母、螺杆与阀盖分体,都可相对运动。
2)根据权力要求1所述阀门,其特征是,相对运动的目的是达到,阀具备更多的开闭手段。
