Description

调温阀
本申请要求于2016年05月31日提交中国专利局、申请号为201610373952.7、发明名称为“调温阀”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及流体控制领域，具体涉及一种调温阀。
背景技术
汽车在行驶过程中各部件之间需要及时以润滑油润滑来保证汽车的正常运行。如果润滑油润滑性能不够好会影响汽车使用寿命。而润滑油的润滑性能和其自身的温度有很大的关联，当润滑油温度过高或者过低时，润滑油的润滑性能会受到影响。
润滑油温度一般在正常行驶时不会过高，当车辆超负荷或在四驱模式设定在雪地行驶或越野时，车辆在液力变矩器过渡打滑状况下行驶，则可能造成变速箱油温度过高，从而失去润滑性能。
现有的变速箱油主要通过调温阀和外部冷却装置组成的冷却流路来实现温度调节功能。当变速箱油路的温度上升时，热动元件的热敏物质受热膨胀，变速箱油直接流回变速箱的通道被封住，高温油进入外部冷却装置进行降温再流回变速箱外部冷却装置。反之，当油温过低时，热动元件的热敏物质开始凝固收缩，顶杆复位，变速箱油直接流回变速箱的通道被打开。变速箱油路的油在流动过程中与发热的变速箱元器件发生热交换，使油温控制在适宜范围。
但在实际使用过程中，当发生由于外部冷却装置阻塞等原因而导致冷却油的流体压力过大时，随着冷却油温度的不断升高，变速箱油直接流回变速箱的通道被封住，会导致变速箱冷却油的流体压力过高、供油不足的问题。

具体实施方式
本发明的技术方案提供一种调温阀，通过在阀体的腔内设置可在压力差和弹簧回复力作用下活动的泄压环，在腔内还设置有能通过泄压环上下活动而打开或关闭的内部通道，正常情况下泄压环关闭内部通道，当泄压 环两端的压力差高于设定值时，流体能够推动泄压环压缩弹簧，从而使内部通道打开，实现第一流道和第二流道同时连通，可以防止系统流体压力过大而造成损害。
本说明书所述的初始形变力是指产品在未使用时处于压缩状态的弹簧受到外力作用要产生形变时产生的压力。
下面结合附图和具体实施方式，对技术方案进行具体说明，本说明书所述的顶部、底部、左侧、右侧等方位名词皆按照附图相应方位关系来阐述的。
图1至图7揭示了本发明的一实施例，调温阀包括内设腔15的阀体1和安装在腔15内的热动元件，腔15的一端开口，热动元件通过腔15的开口端插入腔15内。阀体1还设置有分别可与外部连通的第一接口11、第二接口12、第三接口13和第四接口14。腔15包括第一腔151和第二腔152，第一接口11和第二接口12分别与第一腔151连通，第三接口153和第四接口154分别与第二腔152连通。
其中第一接口11和第二接口12可以设置在阀体的对向位置，第三接口13和第四接口14可以是设置在阀体的对向位置。
这里应当指出，也可以不设置第四接口14，第三接口13与第二腔152连通，并且第三接口13可以是与第二腔152对向设置，也可以是如附图2所示的相交设置。在本实施例中，设置第四接口便于调温阀的管路连接和安装。
这里腔15是指阀体1这一部件上通过一系列钻孔形成的腔体，该腔体内可以设置安装零部件。
热动元件包括热动元件本体22、顶杆21和填充在热动元件本体内的热敏物质，热敏物质能够随着温度的变化而产生体积变化，热敏物质的体积变化推动顶杆21动作，从而能够促使热动元件本体与顶杆相对运动。
腔15的开口端安装有端盖6，端盖6的至少一部分穿过开口端伸入腔15，端盖6与腔15的内壁之间可以通过设置密封圈(图中未示出)进行密封，端盖6可以通过挡圈64固定。
端盖6包括端盖主体65、端盖连接柱66和第二阀座63，其中端盖6通过端盖主体65与腔15的内壁之间设置的密封圈进行密封。第二阀座63 与腔的第一接口11与第二接口12之间部分的内壁间隙配合，第二阀座63中设置有第三阀口631，第三阀口631与热动元件本体22的一端部相配合，当热动元件本体22的该端部与第二阀座63相抵接或者靠接时，热动元件本体22能够关闭第三阀口631，当热动元件本体22的该端部与第二阀座63远离时，第三阀口631打开，第一接口11可以通过第三阀口631与第二接口12连通，此时，调温阀内形成第三流道，第三流道包括第一接口11、第三阀口631和第二接口12。
这里应当说明：1、间隙配合的间隙不大，当调温阀内流入润滑油时，润滑油在该间隙内可以形成油封；2、第二阀座63也可以与端盖6分体设置，第二阀座63可以通过螺纹连接或者铆接等阀室设置在第一腔内，在本实施例中，第二阀座63与端盖6一体设置，端盖6和第二阀座63之间通过端盖连接柱66连接，这种设置方式结构简单，且便于安装，较为容易满足内漏要求。
端盖本体65内还开设有一开口朝向腔15的容纳腔61，从所述容纳腔61朝向腔15的方向或者说从所述容纳腔61开口端向内的方向，容纳腔61内依次设置有弹簧座62和第三弹簧33，弹簧座62呈帽状结构，弹簧座62套设在顶杆21伸入容纳腔61部分顶部的端部，顶杆伸入容纳腔61部分顶部的端部位于弹簧座的内腔。第三弹簧33的一端与容纳腔61的底部相抵接，另一端与弹簧座的外延相抵接，此时第三弹簧33处于压缩状态，第三弹簧33的初始形变力大于等于第一阀口41关闭时第一弹簧31产生的弹性形变力。
这里应当提出，顶杆也可以直接与第三弹簧33相抵接，例如顶杆上一体成型弹簧座，或者第三弹簧套设于顶杆。并且也可以不设置第三弹簧和弹簧座，顶杆直接与端盖相抵接或者靠接。
热动元件2可以通过腔15的开口端装入腔15内，如图所示，热动元件2位于第一腔151内。热动元件2的远离端盖6的一端还设置有第一密封部23，热动元件2通过第一密封部23与设置在腔15内的第一弹簧31相抵接。
如图所示，在腔15中还设置有阀座组件4和泄压环5，其中阀座组件4的一部分位于第一腔151，阀座组件4的另一部分位于第二腔152并且与 第二腔152的内壁之间螺纹连接。
阀座组件4包括第一阀座42、连接柱43、弹簧支撑座44和配合部45，第一阀座42中设置有一贯穿第一阀座42的第一阀口41。
为了便于阀座组件4的安装，第一阀口41至少靠近上端口的部分为一多边形结构的安装部47，例如六边形或者五边形，可以方便通过工具使阀座组件4与第二腔152内壁螺纹连接固定。这里应当指出，也可以通过其它的结构来安装阀座组件4，例如安装部47为在第一阀座42的上端面设置至少两个盲孔，或者安装部47为从第一阀座42的上端面沿第一阀口41的内壁开设有至少两个凹槽，又或者安装部47为从第一阀座42的上端面沿第一阀座42的外壁切削后形成部分。
第一阀座42位于第一腔152，并且第一阀座42的外径小于第一腔152的内径，第一阀座42的外壁与第一腔152的内壁之间形成有一内部通道154。第一阀口41的内径或者第一阀口41的内切圆的直径大于第一弹簧31的外径，第一弹簧31能够穿过第一阀口41且能够自由的被压缩和回复。并且，热动元件2的第一密封部23的外径大于第一阀口41的内壁中任意两点间的最大距离，使第一密封部23能够完全覆盖第一阀口，即当第一密封部23与第一阀座42相抵接时，第一阀口41被关闭。当第一阀座42与第一密封部23相远离时，第一接口11可以通过第一阀口41和通孔46与第三接口13连通，此时调温阀内形成有第二流道，第二流道包括第一接口11、第一阀口41、通孔46和第三接口13。
第一阀座42和弹簧支撑座44之间通过至少两个连接柱43连接，连接柱43的外壁面和内壁面可以为光滑圆弧曲面，且连接柱43的外径小于第一阀座42的外径，两连接柱43之间保持一定的空间。
弹簧支撑座44用于支撑第一弹簧31，第一弹簧31的一端与第一密封部23相抵接，第一弹簧31的另一端与弹簧支撑座44相抵接。为了防止第一弹簧31发生偏移，弹簧支撑座44的与连接柱43相连接部分的端部还可以设置有一凹槽441，凹槽441与所述第一弹簧相配合来防止第一弹簧产生偏移，凹槽441的底部与第一弹簧31的一端相抵接。进一步的，为了便于加工，第一阀口41、连接柱43和凹槽441通过同一工序加工而成，第一阀口41的内壁、连接柱43的内壁和凹槽441的内壁光滑连接，或者第 一阀口41除安装部以外部分的内径、连接柱43的圆弧内壁面的直径和凹槽441的内径相同。
连接柱43的圆弧外壁面的直径与弹簧支撑座44的外径相同，且连接柱43的圆弧外壁面的直径和弹簧支撑座44的外径小于第一阀座42的外径，使第一阀座42相对连接柱43形成有外沿。
配合部45的外壁设置有外螺纹，第二腔152的一部分内壁设置有内螺纹1521，配合部45的外螺纹与第二腔152的内螺纹相配合，从而使阀座组件4安装在腔15内。第一腔151的内径大于第二腔152的内径，使第一腔151与第二腔152连接处形成有肩部。配合部45的外径小于等于弹簧支撑座44的外径，在本实施例中，配合部45的外径小于弹簧支撑座44的外径，这种设置方式便于阀座组件4的安装定位，防止配合部45过度伸入第二腔152内。
阀座组件4中还开设有通孔46，通孔46从凹槽441的底部延伸至配合部45远离凹槽441的端部，通孔46与第三接口13相连通，通孔的内径小于第一弹簧的外径。
阀座组件通过螺纹固定安装在腔15内，可以便于腔的机加工，也便于阀座组件的安装，还能够降低成本。
在第一腔151内还设置有泄压环5，泄压环5的外壁与第一腔151的内壁之间滑动配合，在泄压环5与第一腔151和第二腔152之间的形成的肩部之间还设置有第二弹簧32。第二弹簧32的一端与泄压环5的弹簧支撑部53相抵接，另一端与第一腔151和第二腔152之间的形成的肩部相抵接，第二弹簧32处于压缩状态。
如图5所示，泄压环5为一底部贯通的筒状结构，泄压环5包括底部(图中未示出)、弹簧容纳腔54和侧壁部(图中未示出)，泄压环5的底部包括朝向第一腔151的上端部52和朝向弹簧容纳腔54的弹簧支撑部53。泄压环5的底部还开设有贯穿底部52的第二阀口51，弹簧容纳腔54的内径大于第二阀口51的内径，从而形成有弹簧支撑部53。
第二阀口51的内径小于第一阀座42的外径且大于第一阀口41的内径，这样可以使泄压环5的上端部52与第一阀座42的外沿的下端面在第二弹簧32的作用下相抵接，当泄压环5的上端部52与第一阀座42的外沿 的下端面相抵接时，内部通道154被截断。当泄压环上下两面的压力差大于第二弹簧32的初始形变力时，泄压环5的上端部52远离第一阀座42的外沿的下端面，第一接口11可以通过内部通道154、第二阀口51和通孔46与第三接口13连通。此时调温阀内形成有第一流道，第一流道包括第一接口11、内部通道154、第二阀口51、通孔46和第三接口。
进一步的，为了提高泄压环5的稳定性，第二阀口51的内壁与连接柱43的外壁滑动配合。这种设置方式可以有效的防止泄压环5发生倾斜从而导致泄压环5卡死的问题。
下面介绍调温阀的具体工作方式。图2示出了调温阀正常状态下的润滑油流动路径。在图2所示的状态下，第一阀口打开，第二阀口和第三阀口关闭，调温阀内形成第二流道，润滑油从第一接口流入调温阀后经过第一阀口和通孔后，从第三接口13流出调温阀。这里应当指出，由于润滑油流向油冷器的流阻大于润滑油直接流回变速箱的流阻，在调温阀中也可以不设置第三阀口，当内漏要求较高时，通过设置第三阀口可以有效的降低内漏。
图6示出了调温阀在温度较高时润滑油的流动路径。在图6所示的状态下，第一阀口和第二阀口关闭，第三阀口打开，调温阀内形成第三流道，润滑油从第一接口流入调温阀后经过第三阀口后，从第二接口12流出调温阀。
图7示出了调温阀在故障状态下，例如油冷器堵塞等情况时润滑油的流动路径。在图7所示的状态下，第一阀口关闭，第二阀口和第三阀口打开，调温阀内形成第一流道，润滑油从第一接口流入调温阀后，一部分润滑油穿过第三阀口后，从第二接口12流出调温阀，另一部分润滑油穿过第二阀口和通孔后，从第三接口13流出调温阀。
以上所述，仅是本发明的具体实施例而已，并非对本发明作任何形式上的限制，并且文中所出现的上下左右等方位性词汇均以附图进行描述，并非对其方位进行限制。虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明。任何熟悉本领域的技术人员，在不脱离本发明技术方案范围情况下，都可利用上述揭示技术内容对本发明技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本发 明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均仍属于本发明技术方案保护的范围内。
