Abstract

本实用新型涉及一种泄压阀，包括阀体、弹性件、阀芯和阀盖，阀体上设有输入通道，输出通道和泄压通道，输入通道与输出通道之间设有将两者连通的第一通孔，输入通道与泄压通道之间设有将两者连通的第二通孔，阀芯安装在输入通道一侧将第二通孔封闭，输入通道一侧开口由阀盖封闭，阀芯由塑料制成，所述阀体和阀盖均由塑性材料一次注塑成型制成。与现有技术相比，本实用新型的阀体和阀盖均由非金属的塑性材料一次注塑成型制成，具有加工简便、一致性好、工艺质量可靠和价格低廉的优点。

Description

一种泄压阀
技术领域
本实用新型涉及一种阀门，特别涉及一种泄压阀。 
背景技术
现有的泄压阀，包括阀体、弹性件、阀芯和阀盖，阀体上设有输入通道，输出通道和泄压通道，阀体和阀盖为金属材质，生产成本高，不易加工。 
实用新型内容
本实用新型旨在解决现有技术的上述缺陷，提供一种加工简便、一致性好、工艺质量可靠和价格低廉的泄压阀。 
本实用新型所采用的技术方案为：一种泄压阀，包括阀体、弹性件、阀芯和阀盖，阀体上设有输入通道，输出通道和泄压通道，输入通道与输出通道之间设有将两者连通的第一通孔，输入通道与泄压通道之间设有将两者连通的第二通孔，阀芯安装在输入通道一侧将第二通孔封闭，输入通道一侧开口由阀盖封闭，阀芯由塑料制成，所述阀体和阀盖均由塑料一次注塑成型制成。 
所述弹性件为一弹簧，固定在阀芯与阀盖之间。 
所述阀芯套接一密封帽。 
所述阀盖设有一可带动阀芯移开而使第二通孔开启的旋钮。 
与现有技术相比，本实用新型的阀体和阀盖均由非金属的塑性材料一次注塑成型制成，具有加工简便、一致性好、工艺质量可靠和价格低廉的优点。 
附图说明
图1是本实用新型泄压阀的剖视图； 
图2是图1中阀芯移动使第二通孔开启的剖视图。 
具体实施方式
如图1所示：本实用新型的一种泄压阀，包括阀体1、弹性件2、阀芯3 和阀盖4，阀体1上设有输入通道11，输出通道12和泄压通道13，输入通道11与输出通道12之间设有将两者连通的第一通孔14，输入通道11与泄压通道13之间设有将两者连通的第二通孔15，阀芯3安装在输入通道11右侧将第二通孔15封闭，输入通道11右侧开口由阀盖4封闭，阀芯3由塑料制成，阀体1和阀盖4均由非金属的塑性材料如塑料一次注塑成型制成。 
弹性件2为一弹簧，弹性件2固定在阀芯3与阀盖4之间；阀芯3套接一密封帽5，阀盖4设有一可带动阀芯3移开而使第二通孔15开启的旋钮41。 
如图2所示，当输出通道12堵塞后，阀芯3在压力作用下克服弹性件2弹力移开使第二通孔15开启，也可以手动旋转旋钮41使阀芯3克服弹性件2弹力移开使第二通孔15开启。
