Description

一种带内螺纹平头阀盖
技术领域
本实用新型涉及阀门阀盖,特别涉及一种带内螺纹平头阀盖。
背景技术
阀门是流体输送系统中的控制部件，具有截止、调节、导流、防止逆流、稳压、分流或溢流泄压等功能。用于流体控制系统的阀门，从最简单的截止阀到极为复杂的自控系统中所用的各种阀门，其品种和规格相当繁多。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。
阀盖是阀门的主要零件之一，常见的阀盖与阀体中头是螺栓连接，在工作时阀盖浸泡在介质中，特别是一些腐蚀性介质中如泥浆、油品、液态金属和放射性介质等类型介质极易对螺栓腐蚀导致连接失效对阀门的工作和寿命产生影响。为了提高阀门的实用寿命，因此需要提供一种不易生锈的螺栓连接，阀盖的结构进行改进，使得螺栓与腐蚀介质之间脱离接触避免过快生锈。
实用新型内容
本实用新型的目的就是解决阀盖与压盖螺栓易生锈的问题。
本实用新型采用的技术方案是：一种带内螺纹平头阀盖，它包括阀盖体，阀盖体开设有阀杆孔，所述阀杆孔内设置有与压盖螺纹连接的内螺纹。
本实用新型有益效果是：由于本实用新型在阀盖上设有内螺纹，与压盖螺纹联接后，确保了连接螺丝不与外界环境接触，不易生锈，保证了产品质量，延长了使用寿命，给企业带来效益。
附图说明
如图1为本实用新型的结构示意图。
具体实施方式
    如图1所示，一种带内螺纹平头阀盖，它包括阀盖体1，阀盖体1开设有阀杆孔2，阀杆孔2内设置有与压盖螺纹连接的内螺纹3。
