Abstract

单体气门针是一种用于自行车、三轮车及类似车辆内胎上的一种气门装置,它由主体、副体构成。在主体气体通道上有一个单向阀。具有结构简单、容易制造,使用性能可靠,寿命长等优点,由于不使用乳胶制造的组件,从而消除了现有气门装置所存在的缺陷和不足。

Description

本实用新型涉及一种充气轮胎气门装置,特别是一种自行车一类车辆内胎气门装置。
目前现有的自行车、三轮车,人力车及类似车辆车轮内胎气门均为金属芯柱外套乳胶管的结构型式。由于乳胶管高温时易变质胶粘,其强度、弹性下降以致完全丧失,气门气密性下降,故夏季车辆车胎充气次数频繁,气门胶管更换较勤,而在冬季则由于气温低,天气寒冷,气门胶管变硬,弹性下降,气门的气密性变差,内胎气压不能长久保持,故需要经常充气。再者,气门胶管长时间使用因其发生疲劳和老化也需要进行更换。以上种种缺陷给人们使用车辆带来了诸多不便,同时更换乳胶管使大量优质橡胶被消耗掉。
本实用新型的目的是为消除现有气门装置不足而提供一种使用功能可靠、寿命长,具有结构简单,制造容易,可省去大量优质橡胶的单体气门针。
单体气门针由主体、付体构成。主体气体通道上有一个单向阀。主、付体紧固连接,主、付体连接口处有弹性密封圈以防止充气内胎漏气减压。单向阀阀座与主体整体连接、制造。
单向阀阀座在气体通道环壁上呈环形阶台状,阀体为一可自由活动的曲面体,一般为球体。为保证其动作的可靠性和单向阀的气密性环形阶台台面与阀体相适应使其接触紧密,阀体有限位架对阀体限位。
单体气门针无乳胶组件,从而消除了因使用乳胶材料组件带来的诸多缺陷和不足,不仅省去了大量优质橡胶,而且气门的使用功能更加可靠。具有使用寿命长,结构简单,容易制造等优点。
附图是本实用新型的一种结构的结构示意图,下面结合附图进一步说明本实用新型。
如图所示,单体气门针由带有气体通道的主体(1)与付体(7)胀紧紧固连接而成。主体、付体连接接口处固定有弹性密封圈(2)以防止内胎充气后漏气减压。主体气体通道上有环形阶台与球形阀体(3)构成单向阀结构,球形阀体有一个弹簧制成的限位架(4)对阀体动作限位,付体上有出气口(5),充压气体由出气口进入内胎。主体上有整体连接的导块(6),以便气门针插入并联接在内胎芯座上时导向限位。单体气门针装配与动作过程与现有气门装置基本相同。

Claims (2)

1、一种充气轮胎气门装置,特别是一种自行车一类车辆内胎气门装置,其特征是由主体、付体构成,主体气体通道上有一个单向阀,主付体紧固连接,单向阀阀座与主体整体连接、制造。
2、按权利要求1所述的气门装置,其特征是所说单向阀阀座在气体通道环壁上呈环形阶台状,阀体为一可自由活动的曲面体,一般为球体,阀体有限位架。
