Description

一种具有调压安全泄气功能的耐高压进气阀 技术领域
本申请涉及进气阀领域，特别是涉及一种具有调压安全泄气功能的耐高压进气阀。
背景技术
目前，市面上常见的高压进气阀在使用时，需要打开防尘帽，手动挤压密封活塞，并通过一定的结构，按压到一定位置或是旋转固定住密封活塞，才能实现放气。这期间需要使用很大的外力才能推动密封活塞的露出部分。容易对产品造成损伤，同时易伤到手指。发生安全隐患。
此外，现有进气阀需要使用很大的外力才能推动密封活塞的露出部分，推动密封活塞后，将其固定到一定的位置上才能完成放气。在泄气完成后，很多客户会遗忘重新将密封活塞归位，造成异物进入活塞造成产品失效或者下次充气时因为气阀处于泄气状态造成第一次充气失败。这样也不利于实际使用。

请参考图1、图6及图7，所述进气阀主体4包括裸露在外侧的上平面41,上平面41上包括用于容置第一密封圈2的容置处411，装配后，把持部11位于容置处411上侧，密封部12通过第一密封圈2容置与容置处411内，旋转部13也容置于容置处411内。

具体的，活塞限位部44用于容置密封活塞主体6，活塞限位部44内包括容纳密封活塞限位部6的限位孔442，还包括限位密封活塞限位部6旋转的限位销441。
进气阀主体4外侧包括与进气阀外壳相适配的外螺纹45。
请参考图1、图8和图9，密封活塞主体6贯穿整个进气阀，所述密封活塞主体6包括最底侧与进气阀外壳7接触的活塞下底座63，活塞下底座63上侧包括活塞上底座61，活塞上底座61和活塞下底座63之间包括用于容置第二密封圈5的凹槽631，第二密封圈5容置于密封活塞主体6的凹槽631及进气阀外壳7之间。

请参考图1，所述进气阀外壳7包括与进气阀主体4的外螺纹45相适配的内螺纹71，内螺纹71和外螺纹45相适配使得进气阀外壳7和进气阀主体4咬紧在需充气产品的开口处。

图2为图1沿A-A线剖开的剖面示意图；图3为本发明所述的一种具有调压安全泄气功能的耐高压进气阀的泄气状态示意图；图4为图2沿B-B线剖开的剖面示意图；请参考图1～图4，以下，结合前述附图对本实施例中进气阀的使用过程进行简要说明。
如图1～图2所示，进气阀处于密封状态。
此时，旋转盖体1将排气孔43完全密封，旋转底部133位于底部空隙613处，旋转斜坡132和活塞斜坡612接触，旋转限位部134和凸起顶部611接触，弹性体3的张力作用使得密封活塞主体6和第二密封圈5紧紧与进气阀主体4结合，气体无法从进气阀外壳7上的孔隙72与外界交流。
如图3～图4所示，进气阀处于泄气状态。
此时，旋转旋盖盖体1，旋转盖体1处于可分离的状态，旋转盖体1并未遮住排气孔43，排气孔43可以与外界交流气体。
弹性体3被旋转盖体1压缩，旋转底部133位于凸起顶部611处，被密封活塞主体6的整向下移动，密封活塞主体6和第二密封圈5与进气阀主体4之间存在缝隙，气体可以从进气阀外壳7上的孔隙72通过密封活塞主体6和第二密封圈5与进气阀主体4之间的缝隙进入排气孔43与外界交流。
当需要给进气阀进行充气时，将旋转盖体1整体取下，此时弹性体3的张力作用使得密封活塞主体6和第二密封圈5紧紧与进气阀主体4结合。
充气装置的结构与旋转盖体1结构相似，将充气装置放置于进气阀主体4内，充气装置将密封活塞主体6按压向下进行充气。
当充气完成时，充气装置旋转拔出，弹性体3的的张力作用再次使得密封活塞主体6和第二密封圈5紧紧与进气阀主体4结合，放置气体泄出。
实施例二
本实施中所述的一种具有调压安全泄气功能的耐高压进气阀，其基本构造、工作过程及取得的技术效果与第一实施例提供的耐高压进气阀基本相同，不同之处在于：
图11为本发明所述的一种具有调压安全泄气功能的耐高压进气阀的安全密封装置结构示意图。请参考图1～图11，进气阀主体4内部包括位于最上层的上平面41，上平面41和进气阀主体4的边缘之间包括安全阀凹槽46，安全阀凹槽46内部包括若干个安全阀卡槽47，每个安全阀卡槽47上包括卡位部471，相邻的两个卡位部471之间可以包括安全透气部481和防脱盖限位孔482。
本实施例中所述的进气阀包括安全排气盖81，安全排气盖81容置于安全阀凹槽46内。
具体的，安全排气盖81顶部包括若干个透气孔811。
具有的，安全排气盖81和安全阀凹槽46固定连接，安全排气盖81和安全阀凹槽46接触的一侧设有螺纹，相对应的，安全阀凹槽46相对应的一侧也设有螺纹，安全排气盖81和安全阀凹槽46通过螺纹连接。
进气阀还包括安全排气盖密封圈82，安全排气盖密封圈82位于安全排气盖81的一侧，用于密封安全排气盖81和安全阀凹槽46。
具体的，安全排气盖密封圈82位于安全排气盖81螺纹的另一侧。
进气阀还包括压簧83和安全密封装置84，压簧83和安全密封装置84位于安全阀凹槽46和安全排气盖81形成的空间内部。具体的，安全密封装置84整体呈圆弧状，与安全阀卡槽47的形状相适配，安全密封装置84位于相邻的两个安全阀卡槽47之间。
具体的，安全密封装置84包括用于容置压簧83的压簧容置槽841。
具体的，安全密封装置84还包括容置于安全透气部481内的密封凸起842，当密封凸起842容置于安全透气部481内时，安全透气部481被密封凸起842密封。
具体的，安全密封装置84还包括连接柱844和防脱盖843，防脱盖843位于连接柱844顶部，连接柱844位于防脱盖限位孔482内且可以在防脱盖限位孔482内移动。
优选的，防脱盖843的直径大于连接柱844及防脱盖限位孔482，故而当连接柱844在防脱盖限位孔482内移动时，防脱盖843可以防止安全密封装置84脱出。
优选的，防脱盖843呈顶部尖的帽状，使得防脱盖843便于穿过防脱盖限位孔482。
优选的，本实施例中安全密封装置84的数量为三个，且三个安全密封装置84平均分布在安全阀凹槽46内，便于受力均匀。当然，安全密封装置84的数量也可以根据需要进行调整。
具体的，压簧83顶部与安全排气盖81接触，底部容置于压簧容置槽841和卡位部471内，使得压簧83在自然张力作用下，始终存在安全密封装置84和安全排气盖81相互远离的力，故而安全透气部481、防脱盖限位孔482被密封不会透气。
安全排气盖81是带有螺纹的，安全排气盖81通过和进气阀主体4对应螺纹进行契合，旋紧或是松 开安全排气盖81会导致压簧83的压缩量变化，从而调整压簧83压到安全密封装置84的压力。实现内部保护气压的增加或减小。安全排气盖密封圈82用来提供阻力，防止安全排气盖松脱。
请参考图1～图4，以下，结合附图对本申请的工作原理进行简要说明。
进气阀处于泄气状态时，进气阀连接的主体内部气压和外部气压压强接近，此时，压簧83的自然张力将安全密封装置84压紧，安全透气部481、防脱盖限位孔47不会泄气。
进气阀处于内部的气体属于密封状态时，当进气阀连接的主体内部气压和外部气压产生过大压强差是，内部压强过大，内部气压会将压簧83压缩，安全密封装置84被顶起，安全透气部481、防脱盖限位孔47可有气体通过，当气体从安全透气部481、防脱盖限位孔47通过再从安全排气盖81的透气孔811排出外部。
当内部压强减小后，压簧83的自然张力可以将安全密封装置84按压回安全透气部481、防脱盖限位孔47被堵住的状态，安全密封装置84再次压紧，气体不会通过安全透气部481、防脱盖限位孔47泄出。
充气装置给进气阀连接的主体充气时，当充气装置给进气阀连接主体充气过量时，主体内部压强过大，内部气压会将压簧83压缩，安全密封装置84被顶起，安全透气部481、防脱盖限位孔47可有气体通过，当气体从安全透气部481、防脱盖限位孔47通过再从安全排气盖81的透气孔811排出外部，防止造成因为充气过量发生意外。
以上对本发明的具体实施方式作了详细介绍，对于本技术领域的技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也属于本发明权利要求的保护范围。
