Description

斜面中法兰小口径固定球阀
技术领域
本发明涉及一种球阀，具体涉及一种固定球阀。
背景技术
球阀是一种阀杆带动阀球转动并绕球阀轴线作旋转运动的阀门。球阀包括有阀体、阀球、阀杆以及阀座，如图3所示，一般现有球阀的阀座也是由左阀体与右阀体连接而成的，只是两者安装的面是垂直面，这种结构适合阀球与阀杆分体式结构，而对于阀球与阀杆一体式结构，就无法安装到这种阀体内。然而，对于小口径固定球阀来说，由于阀球较小，除了在上面开流通孔外，还需要在上面开用于连接阀杆的凹槽，这在工艺上很难实现，即使实现了，由于凹槽基面太小，导致阀球容易损坏。因此最好的方式是阀球与阀杆一体成型，然而阀球与阀杆一体成型后，现有普通的阀门结构又无法正常安装。
发明内容
鉴于现有技术存在的不足，本发明创新提供了一种适于阀球与阀杆一体成型安装的斜面中法兰小口径固定球阀。
这种斜面中法兰小口径固定球阀，包括有阀体、阀杆、阀座、阀球以及固定轴，其特征在于：所述阀体由左阀体与右阀体通过螺栓组装而成，所述左阀体具有左安装斜面，所述右阀体具有右安装斜面，所述左阀体的左安装斜面与右阀体的右安装斜面相贴合，所述阀杆位于左阀体上，所述固定轴位于右阀体上，所述阀球位于左阀体与右阀体之间，所述左阀体与右阀体上均螺纹连接有调节座，所述阀座位于阀球与调节座之间，所述调节座可作用于阀座上，所述调节座上具有供工具进入的凹槽。
所述阀体与阀杆一体成型。
所述右阀体的右安装斜面上设有定位凸起，所述左阀体的左安装斜面上设有定位凹槽，所述定位凸起匹配设置于定位凹槽内。
所述调节座与阀座之间设有碟簧。
所述阀座上设有O型密封圈，所述O型密封圈作用在阀体上。
所述阀座上设有柔性石墨盘根。
按照本发明提供的一种斜面中法兰小口径固定球阀，由于左阀体与右阀体通过斜面安装，这样一体成型的阀球与阀杆也实现安装。
附图说明
图1为本发明的结构示意图；
图2为图1为A处的局部放大图；
图3为现有球阀的结构示意图。
1、左阀体；2、右阀体；3、阀球；4、阀杆；5、阀座； 6、调节座；7、固定轴；8、螺栓； 9、碟簧；10、O型密封圈；11、柔性石墨盘根；60、凹槽。
具体实施方式
如图1与图2所示，这种斜面中法兰小口径固定球阀，包括有阀体、阀杆4、阀座5、阀球3以及固定轴7，阀体由左阀体1与右阀体2通过螺栓8组装而成，左阀体1具有左安装斜面，右阀体2具有右安装斜面，左阀体1的左安装斜面与右阀体2的右安装斜面相贴合，阀杆4位于左阀体1上，固定轴7位于右阀体2上，而阀球3位于左阀体1与右阀体2之间，左阀体1与右阀体2上均螺纹连接有调节座6，阀座5位于阀球3与调节座6之间，调节座6可作用于阀座5上，调节座5上具有供工具进入的凹槽60。
安装时，由于左阀体1具有左安装斜面，这样就可以将阀杆4从下往上穿过左阀体1，而阀杆4一体成型的阀球3就靠近左阀体1上的阀座5，之后将右阀体2的右安装斜面与左阀体1的左安装斜面贴合，然后用多个螺栓8将两者固定，阀体安装好后，左阀体1与右阀体2上的两个阀座5均靠近阀球3，接着通过工具进入调节座6的凹槽60，并转动调节座6，由于调节座6是螺纹连接，这样调节座6就推着阀座5向内侧移动，并驱使阀座5作用在阀球3上，这样就完成安装。
这种阀体采用斜面分体结构，适合阀体与阀杆4一体成型结构的安装。当然，阀体与阀杆4分体结构也能安装。
为了方便左阀体1与右阀体2的合并，本发明在右阀体2的右安装斜面上设有定位凸起，而在左阀体1的左安装斜面上设有定位凹槽，合并左阀体1与右阀体2时，只要将定位凸起匹配设置于定位凹槽内就能完成定位，之后拧上螺栓8即可。
为了使阀座5具有一定的弹性，本发明在调节座6与阀座5之间设有碟簧9。碟簧9能使阀座5具有一定的浮动效果，从而与阀球3形成良好的密封效果。
为了使阀座5与阀体之间形成密封，阀座5上设有O型密封圈10，O型密封圈10作用在阀体上。
为了使阀座5与阀体之间形成更好的密封效果，在阀座5上设有柔性石墨盘根11，柔性石墨盘根11能使球阀在高温高压下也能实现良好的部位密封。
