Description

一种球阀的空气弹簧
技术领域
本发明涉及阀门领域，特别是一种球阀的空气弹簧。
背景技术
球阀被广泛的应用在石油炼制、长输管线、化工、造纸、制药、水利、电力、市政、钢铁等行业，在国民经济中占有举足轻重的地位。球阀具有结构简单、可靠、全开情况下流动阻力小等特点，因此，把球阀的性能继续完善对社会的生产也有很大的积极作用。
一般的普通球阀都是由金属与金属互相挤压形成的密封面，在开、闭球阀过程中，需要的力矩较大，特别是在较大型的球阀开启中需要很大的力矩才能顺利开、闭球阀，这样在生产中就显得格外笨重，当阀球卡柱时，球阀在开闭时很可能会造成阀门更大损坏；而阀门的密封而球阀在多次开启后，容易出现球阀密封不严的情况，特别是在输送的液体含有微小的固体颗粒，这些固体颗粒就会使得阀芯与阀座互相摩擦更厉害，由此而需要经常更换阀座，这样就会耽误企业的正常生产。由此，很多厂家在阀座后安装有弹簧，使得弹簧能够减缓阀球对阀座的冲击，同时阀座在磨损后，弹簧能够推动阀座前移，避免密封效果减弱，但是普通的钢弹簧在较久的使用后，弹簧会被腐蚀，弹簧的弹性容易受到影响，降低密封的效果。
发明内容
针对上述密封弹簧存在的问题，本发明的技术目的在于提供一种使得球阀密封效果更好、耐腐蚀、弹性的保持性好的球阀的空气弹簧，在球阀上安装有这种空气弹簧，使得球阀的阀座使用时间更长。
本发明通过以下技术方案实现：
一种球阀的空气弹簧，所述球阀的空气弹簧包括：前承压板、后承压板、弹簧筒、波纹气囊、气嘴，所述弹簧筒包括内筒和外筒，所述前承压板和后承压板分别设于内筒和外筒的圆面上，所述波纹气囊设于弹簧筒的内部，所述波纹气囊内充有空气。
进一步地，所述前承压板的形状为圆形，所述前承压板上设有四个沉头孔，所述沉头孔圆形均匀布置，所述前承压板与内筒螺钉连接，所述螺钉的数量为4个。
进一步地，所述内筒为一端开口的圆筒，所述内筒的开口段安装在外筒内，所述内筒开口的外圆面上设有锁环a，所述内筒的圆面上设有四个螺孔，所述四个螺孔圆形均匀布置。
进一步地，所述外筒为一端开口的圆筒，所述设于外筒上的后承压板上设有四个沉头孔，所述沉头孔圆形均匀布置，所述后承压板与外筒螺钉连接，所述螺钉的数量为4个，所述外筒的圆筒壁面上设有安装气嘴的气嘴孔，所述外筒的开口处的内圆面上设有锁环b，所述锁环b与锁环a互相配合安装，锁环a与锁环b能限制内筒远离外筒的最大移动距离。
进一步地，所述后承压板的形状为圆形，所述后承压板上设有四个沉头孔，所述沉头孔圆形均匀布置，所述前承压板与内筒螺钉连接，所述螺钉的数量为4个。
进一步地，所述波纹气囊的截面形状为波浪形，所述波纹气囊上设有气嘴，所述波纹气囊的材质为聚酰胺纤维或聚酯纤维。
本发明的有益效果是:
1、通过在波纹气囊内充有空气，在波纹气囊的外部安装有弹簧筒，用空气作为弹簧介质，使得弹簧的弹性保持好，弹簧更耐腐蚀，弹簧的可靠性更高；
2、通过在内筒与外筒的圆面上分别安装有前承压板与后承压板，使得空气弹簧在安装时更方便，同时通过在前承压板与后承压板对弹簧筒的保护作用，使得空气弹簧更加耐用，承压板与弹簧筒通过沉头的螺钉，安装空气弹簧时更方便；
3、通过将波纹气囊的截面形状为波浪形，使得气囊在压缩时能够有规律地收缩，使得波纹气囊不会再弹簧筒内扭曲。
