Description

防混隔膜阀 技术领域
本发明涉及一种隔膜阀，尤其是一种防混隔膜阀。
 背景技术
隔膜阀是一种特殊形式的截断阀，常用于食品工业、制药工业等，传统的隔膜阀主要包括有内设阀腔的阀体，阀体内还设有分别导通阀腔的第一流体通道和第二流体通道，阀腔内位于第一流体通道和第二流体通道间设有阀座，阀腔内阀座相对位置设有隔膜，隔膜相对于阀座所在侧的另一侧设有与驱动机构联动的驱动轴，驱动机构可带动驱动轴沿轴向前后移动，然后驱动轴带动隔膜做朝向阀座的线性运动，并使隔膜的表面侧紧靠或离开所述阀座，从而构成第一流体通道和第二流体通道的打开和关闭。但是，由于受到现有技术的限制，传统隔膜阀上隔膜的使用年限和使用强度均有一定的寿命，故当隔膜出现损坏或其它原因造成隔膜无法完全和阀座闭合时，隔膜阀将出现内漏的现象，这种情况在食品工业和制药工业之类，对卫生和生产工艺有严格要求的行业来说都将会造成无法估计的巨额损失。
在食品工业和制药工业生产中，由于卫生要求，通常采用全封闭式生产，并需要对生产中的罐体需要进行必要的灭菌和消毒；同时又由于工艺要求经常需要对不同罐体内的材料进行混合。考虑到存在出现内漏时而无法察觉的情况，现采用的解决方案为：需要进行物料混合的罐体出料管处分别安设一隔膜阀，两隔膜阀之间通过一连接管相导通，连接管管身上再安设有用于灭菌的灭菌用副阀，以及对隔膜阀内进行排空和观察隔膜是否泄漏用的排空用副阀，其中隔膜阀和连接管上灭菌用副阀常闭，连接管上排空用副阀常开。当其中一侧隔膜阀出现内漏时，罐体内的物料就会进入连接管并从排空用副阀处排出，由此即可判断处由隔膜阀出现内漏，从而进行及时的更换，防止造成食品及药物的污染或混料。
虽然上述方案解决了相应的技术问题，但是所采用的技术方案较复杂，需要多个隔膜阀以及连接设备来实施，势必增加了生产成本和维护的费用。
 技术问题
为了克服现有技术的不足，本发明提供了一种结构简单，可及时观察是否发生内漏的防混隔膜阀。
 技术解决方案
本发明解决其技术问题所采用的技术方案是：一种防混隔膜阀，包括有阀体、以及安设于阀体上的驱动轴和驱动机构，所述阀体内设有阀腔、以及分别导通阀腔的第一流体通道和第二流体通道，阀腔内位于第一流体通道和第二流体通道间设有阀座，阀腔内阀座相对位置设有隔膜，隔膜相对于阀座所在侧的另一侧设有与驱动机构联动的驱动轴，驱动机构可带动驱动轴沿轴向前后移动，使隔膜的表面侧紧靠或离开所述阀座，以构成第一流体通道和第二流体通道的打开和关闭，其特征是：所述阀座上朝向隔膜的端面设有容置槽，容置槽贯穿阀腔，当阀座和隔膜处于闭合状态时，容置槽开口端与隔膜形成密封配合，容置槽与隔膜构成密闭的阀副腔，阀体上还设有灭菌用副阀和排空用副阀，灭菌用副阀和排空用副阀分别安设于阀体上阀副腔所在位置并构成导通阀副腔与阀体外部空间的通道。
 有益效果
采用上述技术方案，阀体内阀座左板和阀座右板与隔膜处于闭合状态时，分别形成了两道构成阀腔导通用的开关，当防混隔膜阀闭合时，隔膜分别与阀座左板和阀座右板构成密封配合。如果其中一道密封配合出现泄漏的情况时，管道内的物料将会进入阀副腔内，又由于与阀副腔导通的排空用副阀处于常开状态，则物料会经排空用副阀流出，故通过观察排空用副阀即可判断是否出现内漏情况，从而可对防混隔膜阀进行及时的监测，避免不必要的损失。
本发明的进一步设置为：所述阀座包括有阀座左板和阀座右板，阀座左板和阀座右板相互平行的安设于阀腔内并垂直于隔膜设置，阀座左板和阀座右板的两端贯穿阀腔阀座左板和阀座右板的一侧边为固定边，另一边位密封边，固定边均固定于阀腔内壁上，密封边均朝向隔膜设置，阀座左板和阀座右板间设有间隙并与阀腔内壁构成所述的容置槽，第一流体通道和第二流体通道均分别位于阀座左板和阀座右板的两侧。
采用上述技术方案，阀座左板和阀座右板为板状，避免过多占用原本就狭小的阀腔内的空间，且也相应增加了阀座左板和阀座右板间容置槽的空间，阀座垂直于隔膜的设置，提高了阀座和隔膜的密封性，增强密封效果。
本发明的进一步设置为：所述隔膜上与阀座左板和阀座右板上密封边相对的位置均设有与阀座左板和阀座右板长度相适配的密封条，密封条宽度与密封边的宽度相适配，当阀座和隔膜处于闭合状态时，密封条和密封边构成密封配合。
采用上述技术方案，密封条的设置可提高隔膜和阀座的密封性能，另外，密封条还可采用具有更好密封效果的材料制作并与工艺与隔膜一体设置，以此来进一步提高密封效果。
本发明的进一步设置为：所述阀体上还设有隔膜座，隔膜座中央设有供驱动轴穿过的轴孔，隔膜座的一侧与阀体固定，另一侧与驱动机构固定，隔膜安设于隔膜座上朝向阀腔所在侧的侧壁上，隔膜的外周边缘与轴孔边缘密封固定。
采用上述技术方案，隔膜座的设置提高了隔膜安设时的稳定性，也不容易出现隔膜的破口，同时也方便了隔膜的维护和更换。
本发明的再进一步设置为：所述阀体上设有与阀副腔位置相对应的灭菌口和排空口，灭菌口和排空口对称的安设于阀体上，灭菌口和 排空口均导通阀副腔与阀体外部空间，灭菌用副阀和排空用副阀分别安设于灭菌口和排空口上，灭菌用副阀和排空用副阀均采用传统隔膜阀。
采用上述技术方案，灭菌口和排空口的设置方便了后期更新时增加相应的连接管道，而灭菌用副阀和排空用副阀均采用传统隔膜阀的设置，则与防混隔膜阀的工作场所相适配，且提高了统一更换的快捷程度，也利于维护。
下面结合附图对本发明作进一步描述：

 本发明的最佳实施方式
如图1-6所示，本实施例包括有阀体1、以及安设于阀体1上的隔膜座2、驱动轴4和驱动机构3，阀体1为立方体状，阀体1上设有阀腔11、以及分别导通阀腔11的第一流体通道111和第二流体通道112，阀腔11位于第一流体通道111和第二流体通道112的交界处，第一流体通道111和第二流体通道112对称的设于阀体1两端并位于同一轴线上，阀体1上设有供隔膜5安设的安装口16。隔膜座2中央设有供驱动轴4穿过的轴孔，隔膜座2螺纹连接于阀体1上，隔膜座2上轴孔大小与阀体上安装口16大小相适配，故轴孔通过安装口16导通阀腔11和阀体1外部空间。隔膜5安设于隔膜座2上朝向阀腔11所在侧的侧壁上，隔膜5的外周边缘与轴孔边缘密封固定，隔膜座2与阀体1固定侧所对的另一侧与驱动机构3联动，驱动机构3输出端与驱动轴4联动，驱动机构3可带动驱动轴4沿轴向前后移动，从而驱动轴4使隔膜5的表面侧紧靠或离开所述阀座2，以构成第一流体通道111和第二流体通道112的打开和关闭。其中，驱动轴4与隔膜5联动的端部设有圆形的凸台41，凸台41的直径大于驱动轴4上轴身的直径，驱动轴4上的凸台41与隔膜5固定，故当驱动轴4与隔膜5联动时，凸台41与隔膜5的接触面积较大，则不容易造成隔膜5的破裂和疲劳。驱动机构3可以采用气动、机械或手动，而本发明中的驱动机构3采用气动方式联动驱动轴，由此开启或关闭隔膜阀。
本发明中，如图4、5、6所示，阀座12包括有阀座左板121和阀座右板122，阀座左板121和阀座右板122均为长条的板状，阀座左板121和阀座右板122相互平行且垂直于第一流体通道111和第二流体通道112所在的轴线，阀座左板121和阀座右板122的两端部贯穿阀腔11并分别与阀腔11内壁固定连接。阀座左板121和阀座右板122的一侧边固定于阀腔11内壁上为固定边，另一侧边朝向隔膜5设置为密封边124，阀座左板121和阀座右板122朝向隔膜5设置并与隔膜5所在面相垂直，阀座左板121和阀座右板122间相隔一定距离设置，使得阀座左板121和阀座右板122与阀腔11内壁构成所述的容置槽123。当阀座12和隔膜5处于闭合状态时，隔膜12与阀座左板121和阀座右板122构成密封配合，则容置槽123与隔膜5形成一个密闭的阀副腔13。隔膜5上与阀座左板121和阀座右板122上密封边124相对的位置设有密封条51，密封条51长度和宽度均与密封边124的相适配，当阀座2和隔膜5处于闭合状态时，密封条51紧贴于密封边124上并构成密封配合。防混隔膜阀还包括有灭菌用副阀6和排空用副阀7，阀体1上设有与阀副腔13位置相对应的灭菌口14和排空口15，灭菌口14和排空口15对称的安设于阀体1两侧，灭菌口14和排空口15均导通阀副腔13与阀体1外部空间，灭菌用副阀6和排空用副阀7分别安设于灭菌口14和排空口15上，灭菌用副阀6和排空用副阀7均采用传统隔膜阀。其中，灭菌口14和排空口15设置的位置可以互换，故灭菌用副阀6和排空用副阀7的位置同理可以互换，均不影响本发明的工作效果。
本发明中，阀体内阀座左板121和阀座右板122与隔膜5处于闭合状态时，分别形成了两道构成阀腔11导通用的开关，当防混隔膜阀闭合时，隔膜5分别与阀座左板121和阀座右板122构成密封配合。如果其中一道密封配合出现泄漏的情况时，管道内的物料将会进入阀副腔13内，又由于与阀副腔13导通的排空用副阀7处于常开状态，则物料会经排空用副阀7流出，故通过观察排空用副阀7即可判断是否出现内漏情况，从而可对防混隔膜阀进行及时的监测，避免不必要的损失。其中，阀座左板121和阀座右板122结构为板状，避免过多占用原本就狭小的阀腔11内的空间，且也相应增加了阀座左板121和阀座右板122间容置槽123的空间，阀座2垂直于隔膜5的设置，提高了阀座2和隔膜5的密封性，增强密封效果。隔膜5上密封条的设置可提高隔膜5和阀座2的密封性能，而密封条51也可采用具有更好密封效果的材料制作并与工艺与隔膜5一体设置，以此来进一步提高密封效果。本发明中，隔膜座2的设置提高了隔膜5安设时的密闭性和稳定性，并且不容易出现隔膜5的破口，同时也方便了隔膜5的维护和更换。另外，灭菌口14和排空口15的设置方便了后期更新时增加相应的连接管道，而灭菌用副阀6和排空用副阀7均采用传统隔膜阀的设置，则与防混隔膜阀的工作场所相适配，且提高了统一更换的快捷程度，也利于维护。本发明还可以有其他实施方式，凡采用同等替换或等效变换形成的技术方案，均落在本发明要求保护的范围之内。
