Abstract

泥状轴封，属节能、低碳、高端装备领域，包括：密封泥，内、外挡环，加注接口，推环，弹簧，端盖，轴套。密封腔里头是内挡环，内挡环外是密封泥，密封泥外是外挡环，密封泥上部是加注接口，外挡环外是推环，推环外是弹簧，弹簧外是端盖，密封轴有轴套。此密封技术不仅能耗小，而且可大大延长设备密封时间，减少加注密封泥工作量。

Description

泥状轴封
技术领域
本技术属节能、低碳、高端装备领域，应用于各种泵、釜、透平压缩机等需要密封的机器设备上。
背景技术
现在设备上普遍使用的有：填料密封、机械密封、泥状密封等，泥状密封是新兴技术，其密封好、能耗小，它主要是在密封腔内加入密封泥，密封泥两头有挡环，密封腔开有密封泥加注接口，密封泥有一定预压，当设备运转时密封泥起密封作用，随着设备的运转，密封泥磨损、流失，密封介质开始泄漏，这时用加注抢通过密封泥加注接口补注密封泥，密封介质又不漏了。
 这种密封需要特别关注密封介质泄露，隔段时间，密封介质再次泄漏，又得再次加注密封泥，加注频率较高，这样就导致维护成本高，工作量大。
  为了改进泥状密封维护成本高，工作量大的问题，本发明提供了一种能使密封介质较长时间不漏、加注频率较低、维护成本低、工作量小的泥状密封装置。
发明内容
本发明的技术方案是：密封腔里头有内挡环，内挡环外是密封泥，密封泥外是外挡环，密封泥上部开有加注接口，外挡环外有推环，推环外有弹簧，弹簧外是端盖。
 本发明由于加装了弹簧，当设备运转密封泥磨损、流失时，弹簧会自动补尚密封泥磨损、流失失去的压力，这样就大大延长了设备密封时间，减少了密封泥加注工作量。
附图说明：图示为本技术方案的结构剖视图
下面结合附图做进一步说明，图中1、密封腔里头软密封环，2、轴套，3、密封泥，4、密封泥注射管接口，5、密封腔外口软密封环，6、推环，7、弹簧，8端盖。
 具体实施方式 
       图中密封腔里头是密封泥3内挡环1，内挡环1外是密封泥3，密封泥3外是外挡环5，密封泥3上开有加注接口4，外挡环5外是推环6，推环6外是弹簧7，弹簧7外是端盖8，密封轴有轴套2。设备通过加注接口4加注预压密封泥3，弹簧7压缩，随着设备的运转，密封泥3磨损、流失，内压减小，将造成密封介质泄漏，此时弹簧7伸张释放压力，密封泥3内压得以补尚，使密封泥3内压保持基本不变，密封介质也就不会泄漏。
