Description

一种高密封性蝶阀
技术领域
本发明涉及一种高密封性蝶阀，属于阀门筑技术领域。
背景技术
蝶阀又叫翻板阀，是一种结构简单的调节阀，可用于低压管道介质的开关控制。蝶阀是指关闭件(阀瓣或蝶板)为圆盘，围绕阀杆旋转来达到开启与关闭的一种阀，阀门可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。蝶阀的优点主要表现在启闭方便迅速、省力、流体阻力小，可以经常操作；启闭力矩较小，由于转轴两侧蝶板受介质作用基本相等，而产生转矩的方向相反，因而启闭较省力。
蝶阀的使用非常广泛，其使用的品种和数量仍在继续扩大，并向高温、高压、大口径、高密封性、长寿命、优良的调节特性，以及一阀多功能发展，其可靠性及其他性能指标均达到较高水平。蝶阀的结构原理尤其适合制作大口径阀门，常用的蝶阀有对夹式蝶阀和法兰式蝶阀两种。对夹式蝶阀是用双头螺栓将阀门连接在两管道法兰之间，法兰式蝶阀是阀门上带有法兰，用螺栓将阀门上两端法兰连接在管道法兰上使用过程。现市场上现有蝶阀结构，只由阀杆、蝶阀板、密封垫圈相互组合形成密封。但是，现有的蝶阀一般采用橡胶环密封或者金属环密封，长时间使用后会导致蝶阀的密封性能下降，影响蝶阀的正常使用。因此，现有的技术存在着密封性能较差的问题。
发明内容
本发明主要解决的技术问题，针对目前蝶阀密封性能差的问题，提供了一种高密封性蝶阀。
为了解决上述技术问题，本发明所采用的技术方案是：
一种高密封性蝶阀，包括阀体、阀轴，其特征在于，所述阀体内部连接密封圈，所述密封圈与气圈进行连接，所述阀轴贯穿阀体与连接轴进行连接，所述连接轴与蝶板进行连接，所述阀轴两侧设有固定片，所述阀体底部连接阀座，所述阀座中间设有缓冲弹簧，缓冲弹簧底部与橡胶垫进行连接。
所述密封圈是硅胶圈、橡胶圈中的任意一种。
所述密封圈内部设有连接管，连接管一侧连接斜管，连接管另一端与气圈进行连接。
所述斜管贯穿气圈，且斜管的倾斜方向与水流向相同，且倾斜40～45°。
所述蝶板外圈为凹圈。
所述气圈在充满后，与凹圈进行匹配。
所述阀体、密封圈及气圈可以通过粘结进行结合，也可以通过连接杆进行连接。
本发明的有益技术效果是：
本发明在蝶阀底部设定了缓冲弹簧并且连接了橡胶垫，可以很好的在流体流动过程中，减缓震动，避免对蝶阀由于晃动，造成的密封性能的损伤，其次，本发明在使用过程中，在液体进行流动至蝶阀时，由于蝶板的关闭，对液体进行了阻隔，使液体静置，并且顺着连接斜管、连接管进入气圈，对气圈进行填充，通过气圈的微量的膨胀，使其增加与蝶板表面凹圈的契合程度，进一步增加了密封性能，同时，在蝶板打开后，由于连接斜管的倾斜方向使顺着液体流动方向，因此在液体流动时，由于流速产生的吸力，可以将里面的液体进行吸出来，避免液体的残留。
