Abstract

本实用新型是一种用于热水供暖系统及液体管道系统的自动排气针阀。是由阀体,气体隔离室,导向阀座、密封垫、排气口、阀针、浮球构成。其特征是阀体内浮球半球以上部分的气体始终保留在阀内,从而达到气体隔离的目的,使介质接触不到导向阀座。

Description

隔离式针阀
本发明用于热水供暖系统及液体管道系统的自动排气阀门。
本人发明的隔离式自动排气阀,专利号ZL93241494·X。经过几年的实施应用,气体隔离技术效果很好,但是功能件结构较复杂易损,为此需要改进。
设计本实用新型的目的是简化原专利技术的结构,延长排气阀的使用寿命。
本隔离式针阀是这样实现的,由阀体,气体隔离室,导向阀座,密封垫,排气嘴,阀针,浮球构成。其特征是阀体上部设有气体隔离室,导向阀座设在气体隔离室上,导向阀座内镶有密封垫,导向阀座上设有排气嘴。阀针与浮球固定为一体,作为动作件。
由于采取上述方案,当浮球浮起时,阀针首先与密封垫封闭,阀体内浮球半球以上部分的气体始终保留在阀内,从而达到气体隔离的目的,使介质接触不到导向阀座。
下面结合附图为实施例进一步说明:
图中阀体(1)上部设有气体隔离室(2),导向阀座(3)设在气体隔离室上。导向阀座(3)内镶有密封垫(4),导向阀座(3)上设有排气嘴(5)。阀针(6)与浮球(7)固定为一体,阀针(6)装配在导向阀座(3)内进行工作。工作时阀针(6)与密封垫(4)闭合分开。
工作原理是阀体内的水位高低变化来进行自动排气。

Claims (3)
