Abstract

一种室内消火栓其阀体内的阀杆上连手轮下连阀瓣,阀瓣经密封垫与阀座配合,阀瓣和密封垫均与水平呈45度角,阀杆为双头T形螺纹,这种室内消火栓阻力小,密封性能好,开启速度快。

Description

室内消火栓
本实用新型涉及一种室内消火栓。
现有技术中,室内消火栓的阀杆是单头T形螺纹结构,启闭速度较慢,阀瓣和密封垫平面接触,阻力大,密封性能较差。
本实用新型的目的是提供一种阻力小、密封性能好、开启速度快的室内消火栓。
本实用新型的目的是这样实现的:室内消火栓,其阀体(4)上端有阀盖(2),阀体内有阀杆(3),阀杆上端连有手轮(1)阀杆下端连有阀瓣(5),阀瓣经密封垫(6)与阀座(7)相配合,所述的阀瓣(5)及其相配合的密封垫(6)是与水平呈45度角的,所述的阀杆(3)为双头T形螺纹。
同现有的室内消火栓相比,本实用新型由于阀瓣和密封垫采用45度角,所以提高了密封性能,此外还减少了阻力,双头T形螺纹式阀杆结构提高了开启速度。经实测,密封性能比现有结构提高了一倍。
下面结合附图详细叙述本实用新型的技术解决方案。
图1为本实用新型的结构示意图。
如图,室内消火栓,其阀体4上端有阀盖2,阀体内有阀杆3,阀杆上端连有手轮1阀杆下端连有阀瓣5,阀瓣经密封垫6与阀座7相配合,所述的阀瓣5及其相配合的密封垫6是与水平呈45度角的,所述的阀杆3为双头T形螺纹。
上述的室内消火栓的阀体4和阀盖2之间还设有O形圈9,阀体4上设有接扣8。
使用时,将水带接在接扣8上,开动手轮带动阀杆通过丝母启闭阀门。

Claims (2)
