Abstract

水暖丝堵放风阀,丝堵的中心螺孔底部是锥形 的;丝堵的侧壁上有一个径向的放心孔和销钉孔,销 钉孔中装有限位销钉,在丝堵的中心螺孔中拧有一个 阀杆,阀杆的中部周缘上有凹形的环槽;该放风阀有 结构简单、成本低,不易被拧下丢失的特点。

Description

本实用新型属于水暖器材类。
现有的水暖放风阀,是在暖气片的丝堵的中心螺孔中拧有一个由阀体和阀杆组成的针阀,在阀体的壁上有一个放风孔。这种放风针阀的不足之处是:用金属铜量较多,成本较高,阀体和阀杆很容易被拧下丢失。
本实用新型的目的是:提供一种结构简单的,用铜量少成本低的、不易被拧下丢失的水暖丝堵放风阀。
本实用新型的技术方案是:丝堵的中心螺孔底部是锥形的;丝堵的侧壁上有一个径向的放风孔和销钉孔,销钉孔中装有限位销钉;在丝堵的中心螺孔中拧有一个阀杆,阀杆的中部周缘上有凹形的环槽。
图1是本实用新型的结构示意图。
图中4是拧在暖气片上的丝堵,丝堵的中心螺孔底部是锥形的,侧壁上有一径向的放风孔1和径向的销钉孔,销钉孔中装有限位销钉了;在丝堵的中心螺孔中拧有一个阀杆2,阀杆中部周缘上有凹形的环槽。拧松阀杆2,便进行放风,但阀杆2在销钉3的阻挡下不能被卸掉;当拧紧阀杆2时便停止放风。
该放风阀有结构简单、用铜量少成本低、不易丢失的积极效果。
