The utility model discloses a bottle valve structure, which comprises a valve body, a valve rod and a valve core assembly. The valve core of the valve core assembly is connected with the inner wall of the valve body, and the valve rod and the valve core are circumferentially fixed and axial sliding connection. The valve core is arranged in threaded connection with the valve body, and the opening and closing of the valve core is driven by the valve rod to rotate and rotate the spool, and the valve core can move up and down in the valve body, thereby opening and closing the valve hole in the valve body, thereby realizing the switch of the bottle valve. Because the valve core and valve body are threaded connection, the valve core after closing is very stable and has good sealing performance. Open state, seal between the stem and the body only by the conventional seals can achieve good sealing, but also in the process of using the stem just rotate without axial movement, can reduce the seal wear, thus effectively prolonging the service life of the cylinder valve. It can be seen that the bottle valve of the utility model has the advantages of reasonable structure, good sealing performance and long service life.

瓶阀结构
本技术涉及瓶阀
技术介绍
目前社会上经常出现由于液化石油气泄漏造成的安全事故发生,而此类事故的罪魁祸首是瓶阀。此类瓶阀一般都存在结构不合理、密封性能差、使用寿命短等特点,导致容易出现液化石油气泄漏问题。因此,有必要研发一种结构合理、密封性能好、使用寿命长的瓶阀。
技术实现思路
本技术要解决的技术问题是提供一种结构合理的密封性能好的使用寿命长的瓶阀结构。为解决上述技术问题所采用的技术方案:一种瓶阀结构,包括有阀体、轴向固定在阀体内转动的阀杆以及于阀体内用以封堵阀孔的阀芯组件,其特征在于:所述阀芯组件的阀芯与阀体的内壁螺纹连接,阀杆与阀芯周向固定且轴向滑动连接。在上述基础上,所述阀杆的连接阀芯的端部形成方形插柱,阀芯形成容置插柱插接的插槽。在上述基础上,所述阀芯的底部安装有阀垫,阀杆与阀体之间安装有密封圈。采用本技术所带来的有益效果:本技术的阀芯设成与阀体螺纹连接,阀芯的启闭由阀杆驱动其转动,转动阀芯,阀芯就可在阀体内上下升降,从而打开和关闭阀体内的阀孔,以此实现瓶阀的开关。由于阀芯和阀体是螺纹连接,关闭后的阀芯状态是非常稳定的,密封性能好。开启状态下,阀 ...
