Abstract

一种隔膜式大导程消火栓由阀体1,阀盖4、耐腐橡胶隔膜2、阀杆8、阀杆螺母5、轴销7组成,其特点是阀体的内腔设有台阶与隔膜接触,使传动件与介质通道密封。传动件不与介质接触,无任何填料,防锈蚀,阀杆和阀杆螺母设计为梯形螺纹,具有导程大,启闭扭矩小,速度快,能自锁,安全可靠。

Description

隔膜式大导程消火栓
本实用新型属一种阀门,用于各种介质,特别适用于室内外、地上地下的消火栓。
我国目前已有的消火栓,一般是角式截止阀,阀的主要传动零件是阀杆、阀杆螺母等,因与介质直接接触,容易被锈蚀,阀上的密封填料易被磨损而产生介质的渗漏,增大了启闭扭矩,又因传动件采用单线梯形螺纹,导程小,开启速度慢,不能自锁,给消火工作带来不利。
本实用新型的目的是针对现有消火栓存在的不足而提供一种传动件不与介质接触,且导程大,启闭扭矩小,能自锁和启闭迅速的隔膜式大导程消火栓。
隔膜式大导程消火栓由阀体1、阀盖4、耐腐橡胶隔膜2、阀杆8、阀杆螺母5、轴销7等所组成,其特征是阀体1的内腔设有台阶10为密封面与隔膜2接触,使其传动件与介质通道密封,隔膜2用轴销7与阀瓣9和阀杆8固定,阀体1和阀盖4用螺栓3连接,开启时旋转手柄6,隔膜2随阀杆8上升而离开密封台阶10,使介质经通道流出,阀杆8和阀杆螺母5的设计为多线梯形螺纹,其螺旋升角小于材料所产生的摩擦角,能自锁。
图1是本实用新型的正视剖面图;
下面按附图对本实用新型作进一步说明:
根据图1所示,隔膜式大导程消火栓由阀体1,阀盖4、隔膜2、阀杆8、阀杆螺母5、阀瓣9和轴销7等所组成、阀体1的内腔设有台阶10为密封面与隔膜2接触,使传动件阀杆8与介质通道密封。隔膜2用轴销7与阀瓣9和阀杆8固定,阀盖4和阀体1用螺栓3连接,当旋转手柄6时,隔膜2随阀杆8上升而离开密封台阶10,使介质经过通道流出。
本实用新型与现有消火栓比较有如下优点:
1.导程大、启闭扭矩小、速度快,能自锁,安全可靠。
2.采用隔膜,传动件与介质不接触无锈蚀。
3.取消了填料、无泄漏问题。
