Description

一种旋塞阀
技术领域
本发明涉及一种阀门,特别是涉及一种旋塞阀。 
背景技术
旋塞阀是一种通过旋塞实现与相连管道联通或关闭功能的阀门,普通旋塞阀的阀体与阀塞的连接处密封性较差,容易造成气体或液体的泄露,无法满足人们的需求。
发明内容
为解决现有技术的不足,本发明的目的在于,提供一种密封性较好的旋塞阀。
本发明的技术方案为:一种旋塞阀,包括阀体,所述阀体的上、下两端设有阀盖,其特征是,所述阀体的中部设有柱形旋塞,所述柱形旋塞的上方设有腔体,所述腔体的外壁为橡胶材质,所述腔体的内部设有推进活塞,所述推进活塞的上端连接有旋转螺钉。
前述的一种旋塞阀,其特征是,所述腔体的外周设有填料。
前述的一种旋塞阀,其特征是,所述填料的上方设有填料压套,所述填料压套的上方设有填料压板。
前述的一种旋塞阀,其特征是,所述填料的下方设有填料垫。
前述的一种旋塞阀,其特征是,所述阀盖与阀体之间设有密封圈。
前述的一种旋塞阀,其特征是,所述上端阀盖上设有限位块,所述限位块上连接有卡圈。
本发明所达到的有益效果:柱形旋塞的上方设有腔体,腔体的外壁为橡胶材质,腔体的内部设有推进活塞,推进活塞的上端连接有旋转螺钉,通过螺钉旋转,带动推进活塞向下运动,从而可以压缩气体,起到很好的密封作用。
附图说明
图1是本发明的结构示意图。
具体实施方式
下面结合附图对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案,而不能以此来限制本发明的保护范围。
如图1所示,一种旋塞阀,包括阀体1,所述阀体1的上、下两端设有阀盖2,所述阀体1的中部设有柱形旋塞3,所述柱形旋塞3的上方设有腔体4,所述腔体4的外壁为橡胶材质,所述腔体4的内部设有推进活塞5,所述推进活塞5的上端连接有旋转螺钉6。
优选地,所述腔体4的外周设有填料7。
优选地,所述填料7的上方设有填料压套8,所述填料压套8的上方设有填料压板9。
优选地,所述填料7的下方设有填料垫10。
优选地,所述阀盖2与阀体1之间设有密封圈11。
优选地,所述上端阀盖上设有限位块12,所述限位块12上连接有卡圈13。
本发明柱形旋塞的上方设有腔体4,腔体4的外壁为橡胶材质,腔体4的内部设有推进活塞5,推进活塞5的上端连接有旋转螺钉6,通过螺钉6旋转,带动推进活塞5向下运动,从而可以压缩气体,起到很好的密封作用。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明技术原理的前提下,还可以做出若干改进和变形,这些改进和变形也应视为本发明的保护范围。
