Description

一种燃气压力调节装置 技术领域
本发明涉及燃气压力调节领域，具体地说是一种燃气压力调节装置。
背景技术
燃气压力调节装置(也称为燃气调压阀)是直杆式和杠杆式压差反馈控制调压的装置。气瓶里的燃气是液态的，压力太高，必须减压才适合通往炉具燃烧。原理是：高压介质通过一个小孔充到一个相对较大的腔里实现减压，实际上是靠截流减压，膜片或活塞的两面一面是出口腔，一面是人为给的压力，并且控制小孔大小的阀杆和膜片(活塞)相连，这样只要给一个固定的压力，那么出口腔的压力就会一直等于这个压力，这个认为给定的压力可以有弹簧或气源或液压源来提供。
目前国内外厂家采用的多为杠杆式减压结构来驱动膜片组件的移动，从而实现调压腔的压力调整，最终使得出口端以稳定的压力输出，即实现燃气的减压功能。现有的杠杆式结构如图1所示，其结构中的调节机构中包括杠杆垫100、杠杆销110、杠杆120、膜片螺钉130、压紧螺母140等众多内部控制零件，由此可见现有的调压器结构存在以下缺点：
1、产品零件多，零件采购成本和零件组装成本相对技术方案偏高。
2、零件相互配合存在误差，造成产品性能偏差。也会因零件尺寸偏差、装配误差等原因造成产品泄漏，功能失效等现象。
发明内容
本发明所要解决的技术问题是：克服现有技术的缺陷，提供一种燃气压力调节装置，其结构简单、零部件数量少，并且能够有效降低因零件失效导致产品泄漏等不安全情况发生的风险，有效保证稳定的调压性能。
本发明所采取的技术方案是：提供一种燃气压力调节装置，包括上壳体和下壳体，所述上壳体与下壳体之间设有调压腔，所述调压腔内设有膜片组件，所述下壳体的一端设有进气口以及用于连通进气口与调压腔的阀口，所述下壳体的另一端设有与调压腔连通的出气口，所述下壳体近阀口的一端设有第一支点，所述上壳体与第一支点相对的位置设有第二支点，所述膜片组件的一端穿过第一支点与第二支点之间的通道连接在调压腔一端侧壁 上，所述膜片组件的另一端连接在调压腔另一端的侧壁上；所述膜片组件可绕着第一支点或第二支点转动，以实现阀口开度的调节，所述膜片组件远离阀口的一端与上壳体之间设有弹性复位件。

作为改进的，所述下壳体近进气口的一端设有朝着调压腔延伸的安装台阶，所述阀口外凸的设在安装台阶近进气口的一端；所述第一支点凸设在安装台阶的另一端。此改进结构中在下壳体内设置了相应的安装台阶，使得阀口以及第一支点的加工更加的方便，保证膜片组件的翻转更加的灵活，提高调压稳定性。
再改进的，所述第一支点与第二支点沿着进气方向上错位设置，且所述第二支点沿进气方向位于阀口与第一支点之间。此改进结构中通过对第一支点与第二支点进行错位的设计，使得膜片组件能够以最佳的状态实现往上翻转或往下翻转运动。
优选的，所述的膜片组件包括橡胶膜片和膜片垫，所述膜片垫覆装在橡胶膜片的上端；所述膜片垫的面积小于橡胶膜片的面积，所述橡胶膜片的周向外边缘连接在调压腔的侧壁上。此结构中的橡胶膜片主要用于实现调压腔中的上下两个区域的压力传递以及压力平衡作用，而膜片垫用于支撑橡胶膜片，有助于整个膜片组件绕着支点的翻转。
再改进的，所述膜片垫近出气口一端的下表面外凸的设有限位凸台，所述橡胶膜片上设有与限位凸台相配合的限位凹槽；且所述橡胶膜片与膜片垫之间设有至少一个定位组件。此改进结构使的橡胶膜片与膜片垫配装后结构更加的稳定，并且使得整个膜片组件的绕着对应支点翻转时更加的稳定，灵活。
优选的，所述的定位组件包括一体成型在橡胶膜片上的定位柱，所述膜片垫上设有与定位柱相配合的定位孔。此结构中的定位结构简单，定位稳定，加工方便，成本低。
再改进的，所述膜片垫背离橡胶膜片一侧的周向外边缘往上翻折形成挡边，且所述膜片垫上位于挡边内部设有加强凸筋。此结构中设置的挡边以及加强凸筋均是为了有效提高膜片垫的结构强度，从而保证整个膜片组件能够稳定的绕着相应的支点翻转运动。
再改进的，所述限位凸台背离橡胶膜片的一侧内凹形成第一定位槽，所述上壳体的内侧壁上设有与第一定位槽相对应的第二定位槽，所述弹性复位件的两端分别配合在第一定 位槽、第二定位槽内。此改进结构使得弹性复位件的安装定位更加的稳定、可靠，从而保证膜片组件的翻翘转动更加的平稳。
优选的，所述的弹性复位件为圆柱弹簧。此结构中采用圆柱弹簧作为复位件，结构简单，弹性力稳定，能够实现膜片组件对于调压腔上下两个区域的稳定调压。

如图2、3、6所示，本发明提供了一种燃气压力调节装置，包括上壳体1和下壳体2， 在下壳体2上设有一个上部开口的安装腔，上壳体1覆装在安装腔的上部，以使得在上壳体1与下壳体2之间形成一个调压腔3，在调压腔3内设有膜片组件4；另外的，在下壳体2的一端设有进气口2.1以及用于连通进气口2.1与调压腔3的阀口2.3，且该阀口2.3的开口部朝上，下壳体2的另一端设有与调压腔3连通的出气口2.2，下壳体2近阀口2.3的一端设有第一支点5，具体的，第一支点5也是朝上外凸设置；上壳体1与第一支点5相对的位置设有第二支点6，第二支点6朝下外凸设置，并且在第一支点5与第二支点6之间设有通道；膜片组件4的一端穿过第一支点5与第二支点6之间的通道连接在调压腔3一端侧壁上，膜片组件4的另一端连接在调压腔3另一端的侧壁上；膜片组件4近阀口的一端可绕着第一支点5或第二支点6转动，以实现阀口2.3开度大小的调节，并且膜片组件4远离阀口2.3的一端与上壳体1之间设有弹性复位件7。如图1所示，在实际使用过程中，在下壳体2的进气口2.1处通常连接有一个专用的进气接头20，用于与气罐快速连接。
具体的调压过程为：
当进气口2.1无进气压力时，弹性复位件7用于驱动膜片组件4远离阀口2.3的一端绕着第一支点5往下翻转，以使得膜片组件4近靠阀口2.3的一端朝着远离阀口2.3的方向运动，直至阀口2.3处于最大开启状态，如图6所示；
当进气口2.1有燃气进入，且出气口2.2有燃气输出时，燃气会通过阀口2.3进入到调压腔3，调压腔3内气压升高，但此时调压腔3中的气压小于弹性复位件7的弹力，不足以将整个膜片组件4往上顶起，这时膜片组件4远离阀口2.3的一端绕着第一支点5往上翻转，以使得膜片组件4近阀口2.3的一端朝着阀口2.3位置运动，阀口2.3的开度减小，从而降低了燃气进入调压腔3的流量；当进气流量持续下降后，调压腔3内的压力随之减小，这时在弹性复位件7作用下，膜片组件4远离阀口2.3的一端又绕着第一支点5往下翻转，以使得膜片组件4近靠阀口2.3的一端朝着远离阀口2.3的方向运动，使得阀口2.3开度逐渐被打开，这样循环往复动作就实现了燃气的减压功能，实现出气口2.2燃气的稳定输出，如图7所示；
当进气口2.1有进气压力，出气口2.2无燃气输出时，调压腔3内气压升高达到设定压力值后，此时调压腔3中的气压足以将整个膜片组件3往上顶起，并且膜片组件4远离阀口2.3的一端绕着第二支点6往上翻转，以使得膜片组件4近阀口2.3的一端朝着阀口2.3位置运动直至膜片组件4完全封堵住阀口2.3上端面，此时阀口2.3处于关闭状态，调压腔3内压力不再升高，如图8所示。
如图6所示，在下壳体2近进气口2.1的一端设有朝着调压腔3延伸的安装台阶8， 阀口2.3外凸的设在安装台阶8近进气口2.1一端的上端面；相应的，第一支点5凸设在安装台阶8的另一端的上端面，从而保证膜片组件4绕着第一支点5翻转运动时，能够更好的实现对于阀口2.3开度的控制。
再一方面的，本实施例中，第一支点5与第二支点6沿着进气方向上是错位设置的，即，第一支点5与第二支点6在竖直方向上不在同一平面内，且第二支点6沿进气方向位于阀口2.3与第一支点5之间。本实施例的结构中，第一支点5和第二支点6呈错位的角度设置，当出气口2.2有燃气输出时，膜片组件4翻转动作起作用的是第一支点5，可以根据流量需求调整第一支点5和阀口2.3之间的位置使其开阀幅度更大，以满足流量输出要求，此结构中，第一支点5距离阀口2.3的位置越远，理论上当膜片组件4远离阀口2.3一端往下翻转时，阀口2.3的开度可以达到更大，可以更好的满足流量输出要求。当阀口2.3需要关闭时，膜片组件4翻转动作起作用的是第二支点6，调整第二支点6和阀口2.3之间的位置使其达到最佳杠杆比例，(第二支点6离阀口2.3越近理论其关闭压力越低)，使关闭压力尽可能的控制的更低，这种情况下，当实现流量和关闭压力能够满足要求并有余量时，可以尽可能的减小壳体尺寸，达到材料以及各方面成本的降低。
本实施例中，优选的，如图3、6所示，膜片组件4包括橡胶膜片4.1和膜片垫4.2，膜片垫4.2覆装在橡胶膜片4.1的上端；膜片垫4.2的面积小于橡胶膜片4.1的面积，并且橡胶膜片4.1的周向外边缘连接在调压腔3的侧壁上。
膜片垫4.2近出气口2.1一端的下表面外凸的设有限位凸台4.2.1，橡胶膜片4.1上设有与限位凸台4.2.1相配合的限位凹槽4.1.1；且橡胶膜片4.1与膜片垫4.2之间设有至少一个定位组件。具体的，定位组件包括一体成型在橡胶膜片4.1上的定位柱4.1.2，膜片垫4.2上设有与定位柱4.1.2相配合的定位孔4.2.2。限位凸台4.2.1背离橡胶膜片4.1的一侧内凹形成第一定位槽9，上壳体1的内侧壁上设有与第一定位槽9相对应的第二定位槽10，弹性复位件7的两端分别配合在第一定位槽9、第二定位槽10内。优选的，弹性复位件7为圆柱弹簧。在其他的实施例中，弹性复位件7也可以是橡胶波纹管或者弹簧板。
上述结构中，膜片垫4.2近出气口2.2的一端往下凹陷形成第一定位槽9，此时该下沉式的第一定位槽9的外侧壁即形成了限位凸台4.2.1，这中结构中膜片垫4.2主体、第一定位槽9以及限位凸台4.2.1一体式加工成型即可。此结构中的膜片垫4.2可以是金属材质，也可以采用高强度的塑料材质，当采用塑料材质时，直接一次性注塑成型即可，加工方便，可以批量化生产，降低成本。
再一方面的，由于膜片垫4.2的整体厚度比较薄，为了保证膜片垫4.2的结构强度，在膜片垫4.2背离橡胶膜片4.1一侧的周向外边缘往上翻折形成环形的挡边4.2.3，并且在膜片垫4.2上位于挡边4.2.3内部设有加强凸筋4.2.4，如图2所示，在挡边4.2.3的内壁凸设有多根加强凸筋4.2.4，并且多根加强凸筋4.2.4是互相交错设置的，有效保证膜片垫4.2的底部强度。
以上就本发明较佳的实施例作了说明，但不能理解为是对权利要求的限制。本发明不仅局限于以上实施例，其具体结构允许有变化，凡在本发明独立要求的保护范围内所作的各种变化均在本发明的保护范围内。
