Abstract

本实用新型提供一种油田用新型调剖泵，以改善调剖泵的介质输送形式、提高输送效率。它具有作为壳体的缸体，在缸体内对称装有控制流体通过的阀组件，所述阀组件由阀座和阀芯构成，且阀座为锥面，阀芯上装有橡胶密封圈实现与阀座锥面的密封。本实用新型将阀座的装配形式改为锥面固定，优点是零部件减少，装配简单，外形轻巧，检修省时省力。将阀密封面改为橡胶软密封，改善了调剖泵的介质输送形式、提高了输送效率，结构简单，磨损小，寿命长。同时，由于是柔软界面，不会切断输送介质的分子链，不会破坏输送介质的物理特性。

Description

油田用新型调剖泵
技术领域
本实用新型属于液体输送装置，特别是一种油田用新型调剖泵。
背景技术
目前国内各大油田使用的调剖泵，阀座的装配形式为垂直固定式，零部件过多，装配繁琐，致使泵体积笨重，导致用户检修泵时困难多，耗工费时，维修费用过高，同时阀密封面为金属硬密封，阀组件寿命短，更换太频繁，生产成本高，更为关键的是金属面纸件剪切力很大，会严重破坏输送介质的大分子链，造成介质物理性能下降。
发明内容
本实用新型目的是提供一种油田用新型调剖泵，以改善调剖泵的介质输送形式、提高输送效率。
具体地说，油田用新型调剖泵，具有作为壳体的缸体，在缸体内对称装有控制流体通过的阀组件，所述阀组件由阀座和阀芯构成，且阀座为锥面，阀芯上装有橡胶密封圈实现与阀座锥面的密封。
本实用新型将阀座的装配形式改为锥面固定，优点是零部件减少，装配简单，外形轻巧，检修省时省力。将阀密封面改为橡胶软密封，改善了调剖泵的介质输送形式、提高了输送效率，结构简单，磨损小，寿命长。同时，由于是柔软界面，不会切断输送介质的分子链，不会破坏输送介质的物理特性。
附图说明
图为本实用新型结构示意图。
具体实施方式
如图所示，油田用新型调剖泵，具有作为壳体的缸体1，在缸体1内对称装有控制流体通过的阀组件，其特征是所述阀组件由阀座4和阀芯(3)构成，且阀座4为锥面，阀芯3上装有橡胶密封圈2实现与阀座4锥面的密封。
本实用新型与现有调剖泵比较，只是将阀座的装配形式改为锥面固定，同时将阀密封面改为橡胶软密封，其余结构都没有变化，这里对其详细结构和工作原理不再描述。
