Abstract

一种自密封平板闸阀。主要解决现有闸阀的阀座及闸板易腐蚀的问题。其特征在于：阀座(2)与闸板(1)接触面分别固有尼龙(3)。该自密封平板闸阀不仅防腐性能好，而且使用寿命长。

Description

自密封平板闸阀
技术领域：
本实用新型涉及油田采油领域所用的闸门，尤其是自密封平板闸阀。
背景技术：
在油田采油及天然气、煤气、水及采暖过程中，井口均通过闸门与管道相连，通过闸门来控制液流的开启关闭或流量大小。而现有的闸门因阀座密封面与闸板的长期接触，使阀座及闸板腐蚀，造成闸阀关闭不严液体泄漏，并且缩短了闸阀的使用寿命，影响正常生产。
实用新型内容：
为了克服现有闸阀的阀座及闸板易腐蚀的不足，本实用新型提供一种自密封平板闸阀，该自密封平板闸阀不仅防腐性能好，而且使用寿命长。
本实用新型的技术方案是：该自密封平板闸阀包括阀座及闸板，阀座与闸板接触面分别固有尼龙。
本实用新型具有的有益效果是：该自密封平板闸阀由于采用了上述方案，在阀座与闸板接触面分别固有尼龙，这样可有效的解决了阀座密封面与闸板的长期接触，使闸板腐蚀，造成闸阀关闭不严产生液体泄漏的问题，而且提高闸门的使用寿命，适用性强，适宜推广应用。
附图说明：
附图1是本实用新型的结构剖视图。
图中1-闸板，2-阀座，3-尼龙。
具体实施方式：
下面结合附图将对本实用新型作进一步说明：
由图1所示，该自密封平板闸阀包括阀座2及闸板1，阀座(2)与闸板1接触面分别固有尼龙3。因闸板1与阀座2接触面分别固有尼龙3，尼龙3的抗腐蚀性强，这样可有效地防止闸板1及阀座2的腐蚀，解决了阀座2密封面与闸板1的长期接触，使闸板1及阀座2腐蚀，造成液体泄漏的问题，而且提高闸门的使用寿命，适用性强，适宜推广应用。
