Description

氟塑料全衬切断球阀
技术领域
本发明涉及一种阀门，具体涉及一种用于强酸、强碱管路上使用的切断球阀的制造技术领域。
背景技术
目前，氯碱化工行业的阀门，通常为密封性能一般的普通远程切断阀门。普通阀门无论从材料还是结构都不具备专用的特点，一方面这种阀门隔膜片密封性能不好，隔膜易损坏，并不能很好地阻止介质的泄漏；另一方面在强酸强碱场合、有毒有害的工艺条件下，往往密封性能差，易泄漏，壳体易穿孔，膜片易破裂，使用寿命短，不能满足设备管路长期有效输送有毒、有害介质的特殊要求。
发明内容
为了克服现有技术存在的问题，本发明提供一种氟塑料全衬切断球阀。
本发明包括阀体、阀座、阀盖、阀杆、阀球，所述阀体设有进口、出口、上端连接口，所述进出口分别连接有进出口法兰，所述阀盖通过螺栓、螺母固定在所述阀体的上端连接口处，所述阀杆穿过所述阀盖固定，所述阀杆与所述阀盖之间设置填料密封；所述阀球设置在所述阀体内，所述阀杆与所述阀球通过铸造一体设置，所述阀体内侧壁全衬氟塑料层，所述阀球内、外表面、设置于阀体内的阀杆上分别设置氟塑料层，所述阀盖内侧表面设置氟塑料层。
本发明所述球体上部设置阀杆，与球体整体锻造后经专用机床加工而成，解决以往球体与阀杆焊接后，阀杆受力容易与球体断裂的问题，阀杆与球体断裂，阀门无法启闭，杜绝事故的发生；阀体、阀球全衬氟塑料，使得发明在强酸、强碱环境下的可靠运行，具有很强的耐腐蚀性。
本发明所述阀球进出端部与所述阀体之间设置密封垫，所述阀球进出侧的阀体上分别设有环形台阶，所述密封垫配合在所述环形台阶内。密封垫保证了阀体的密封性能，无泄漏，安全可靠。
本发明所述阀球基体上设置若干分布均匀的通孔，氟塑料层融入所述通孔内与阀球内外表面的氟塑料层熔为一体。通孔中熔入的氟塑料与球体内、外表面的氟塑料熔为一体，连接球体内外的塑料层，解决了起层、鼓包、脱落的问题。
本发明所述进出口法兰上分别衬氟塑料层，进出口法兰上的氟塑料层与阀体内表面的氟塑料层一体设置。法兰面衬塑料进一步保证了阀门的耐腐蚀性能，更为安全可靠。
本发明在所述阀体内表面、进出口法兰端面分别设置分别均匀的燕尾槽，所述氟塑料层熔入各所述燕尾槽内。通过设置燕尾槽，使得阀体内表面、法兰面的氟塑料层不起层，杜绝了衬里鼓包，有毒、有害介质泄漏的问题。
本发明所述阀体由左、右阀体组成，左右阀体之间通过螺栓、螺母固定连接，左右阀体内侧壁、连接端面分别全衬氟塑料层。两端阀体的设置方便部件的安装，同时便于阀体的制造。
本发明在所述阀杆的开启端连接防爆智能气装，所述防爆智能气装通过支撑架固定在所述阀体上。防爆智能气装为STI防爆切断型气动执行器，可实现远程控制的可靠性。
本发明所述防爆智能气装为气动执行器，所述气动执行器为阀门专用气动执行器。
附图说明
