Description

一种压差旁通阀
技术领域
本发明涉及一种旁通阀，具体提供一种压差旁通阀。
背景技术
现有技术下的旁通阀，尤其是应用于低暖设备中的旁通阀，其在应用时往往存在密封不严、可调节性较差等情况。
发明内容
本发明是针对以上不足，提供一种压差旁通阀，其具有止回流性、可调节性、设计合理性等优点，当部分房间达到温度要求时，会使得部分地暖分发管路关闭，这时自力式压差旁通阀启动，使得多余的水量旁通回锅炉，保证系统安全运行。
本发明解决其技术问题所采用的技术方案是：
一种压差旁通阀，包括阀体，所述阀体上方连接有阀帽，所述阀体内设置有阀芯组件，所述阀芯组件上方连接设置于阀帽内部的阀杆，所述阀杆顶部通过螺钉连接手柄，所述阀杆外部设置有弹簧。
阀帽和阀体之间设置有O形圈。
阀杆上部设置有阀杆帽，顶部设置有弹簧卡圈。
阀杆与阀帽之间设置有O形圈。
本发明的一种压差旁通阀与现有技术相比，具有止回流性、可调节性、设计合理性等优点，当部分房间达到温度要求时，会使得部分地暖分发管路关闭，这时自力式压差旁通阀启动，使得多余的水量旁通回锅炉，保证系统安全运行。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1为本发明的一种压差旁通阀的结构俯视图；
图2为图1的A-A向剖视图。
具体实施方式
下面结合附图和具体实施例对本发明的压差旁通阀作进一步的描述。
如附图所示，一种压差旁通阀，包括阀体1，所述阀体1上方连接有阀帽4，所述阀体1内设置有阀芯组件2，所述阀芯组件2上方连接设置于阀帽4内部的阀杆6，所述阀杆6顶部通过螺钉11连接手柄8，所述阀杆6外部设置有弹簧5。
阀帽4和阀体1之间设置有O形圈3。
阀杆6上部设置有阀杆帽7，顶部设置有弹簧卡圈10。
阀杆6与阀帽4之间设置有O形圈9。
本发明的压差旁通阀，其阀芯组件2上端伸出阀帽4与手柄8固定连接，阀芯组件2下端设置有橡胶垫片可与阀体1形成密封面接触，通过手柄8与弹簧5或进、出水口中的压力差可调节旁通阀的开度和流量。当手柄8调到开度最大时，弹簧5处于自然伸长或压缩状态，此时进水口要开启密封面的压力就设置在了某一个数值，当手柄8调到开度最小时弹簧5处于压缩状态，此时进水口要开启密封面的压力又设置在了某一个数值。本发明具有止回流性、可调节性、设计合理性等优点。当部分房间达到温度要求时，会使得部分地暖分发管路关闭。这时自力式压差旁通阀启动，使得多余的水量旁通回锅炉，保证系统安全运行。
以上所述的实施例，只是本发明较优选的具体实施方式的一种，本领域的技术人员在本发明技术方案范围内进行的通常变化和替换都应包含在本发明的保护范围内。
