在中国发明专利说明书CN 105351538 A中公开了一种上装式蝶阀，其主要包括：阀体，具有空腔，空腔的两端具有供介质流通的入口和出口，顶部具有开口，底部设有安装槽，阀体内壁出口上设置有阀座密封圈；阀盖(3)，通过紧固件固定安装在阀体上，阀体与阀盖(3)之间设有金属缠绕垫(10)密封；阀杆(4)，垂直于阀体内介质流向，通过阀盖(3)、限位组件与阀体成轴向固定，轴向转动配合联接；蝶板，通过键连接固定于阀杆(4)上；蝶板密封圈通过压板固定在蝶板上；限位组件，套于阀杆(4)外侧，并安装于阀盖(3)与阀体围成的空腔内；
上述的上装式蝶阀安装时需要先将第二限位块安装于阀体内，然后将阀杆(4)、蝶板、蝶板密封圈等的组合件装入到阀体内，再将第一限位块装于阀盖(3)与阀杆(4)组件之间，最后将阀盖(3)套于阀杆(4)外侧并通过紧固件与阀体固定连接。由于阀座密封圈设置在出口阀体内壁上，当阀座出现损伤需要更换时，只能切割管道，做修复处理，维修难度大、成本高；其次限位组件与阀杆(4)组件轴向紧密配合，还要保证与阀座密封圈的位置相对准确，尺寸精度要求极高，增加了加工及装配难度；另外若要调整阀座密封圈与蝶板密封圈之间的密封比压，只能多次拆装，现场试压，因此对现场操作条件要求苛刻。因此设计一种上装式蝶阀以解决上述问题是十分有必要的。
发明内容
本发明的目的在于提供一种上装式蝶阀，降低加工、装配、试压的整体难度，提升密封圈的密封性能，真正做到阀内件整体拆装，蝶板密封圈和阀座密封圈均可维修更换；另外内阀体可以线下试压无误后再安装到现场管道上，大大提高维修效率。
为了解决上述技术问题，本发明提供如下技术方案：一种上装式蝶阀，包括外阀体、内阀体、阀盖、阀杆、蝶板、阀座密封圈、蝶板密封圈、压盘、压盘垫片、金属缠绕垫、阀盖缠绕垫、弹性调整垫片、对开环、丝堵、圆柱销和轴套，所述外阀体和内阀体均具有空腔，且空腔的两端均开设有供介质流通的入口、出口，所述外阀体和内阀体的入口、出口外侧各设有角度为5°的斜平面，且内阀体的入口侧设有卸压孔，所述内阀体的出口侧5°斜平面上设有凹槽，且凹槽内装有金属缠绕垫，所述内阀体前后两侧设有相互平行的两个平面，所述内阀体通过入口、出口5°斜平面和前后相互平行的两平面装于外阀体上，所述内阀体的上端同时留有数个凹槽，且凹槽内设置有弹性调整垫片；所述阀盖套于阀杆外侧，并通过紧固件固定在外阀体的顶部，所述阀盖底部设有凸台，且凸台与外阀体顶部凹槽相互压紧阀盖缠绕垫形成密封；所述阀杆底部设有台阶，且外侧设有轴套与内阀体配合连接。
作为本发明进一步的方案：所述外阀体的顶部具有开口和凹槽，且底部开设有安装槽和吹扫孔，所述外阀体前后面上设置有相互平行的凸条，且外阀体的底部设置有丝堵。
作为本发明进一步的方案：所述内阀体顶部和底部分别开设有孔和安装槽，且空腔的出口端设置台阶。
作为本发明进一步的方案：所述内阀体的上下两端预留有螺纹孔。
作为本发明进一步的方案：所述阀杆还通过对开环和紧固件装于内阀体上。
作为本发明进一步的方案：所述阀座密封圈通过压盘、压盘垫片和紧固件利用内阀体出口端的台阶固定在内阀体上。
作为本发明进一步的方案：所述蝶板密封圈通过紧固件安装于蝶板上，且蝶板通过圆柱销安装于阀杆上。
与现有技术相比，本发明所达到的有益效果是：该上装式蝶阀，可以整体一次性拆卸，只需打开上盖即可，同时可方便的更换蝶板密封圈和阀座密封圈，并调整密封圈的相对位置，保证足够的密封比压；另外可利用内阀体上下两端预留的螺纹孔在线下试压，大大提高安装及检修效率。

蝶板密封圈7通过紧固件安装于蝶板5上，且蝶板5通过圆柱销15安装于阀杆4上。
基于上述，本发明安装时，先将阀杆4穿过内阀体2和蝶板5，用圆柱销15将蝶板5固定于内阀体2上；将蝶板密封圈7固定于蝶板5上；阀座密封圈6通过压盘8、压盘垫片9和紧固件固定在内阀体2上；将组装并试压完成的内阀体2装于外阀体1围成的空腔内，通过5°斜平面保证外阀体1与内阀体2之间的密封；将弹性调整垫片12和金属缠绕垫10装于内阀体2与阀盖3之间和外阀体1与阀盖3之间，调整外阀体1与内阀体2垂直方向的相对位置，并使用标准件紧固，最后安装填料函填料并紧固即可完成安装；拆卸蝶阀各部件的顺序与安装各部件的顺序相反。
