Description

双板式调节阀
技术领域
本发明涉及阀门领域，尤其是一种双板式调节阀。
背景技术
以往使用的流量控制阀存在以下不足：1、调节流量时，由于用来调节流量的套筒受到介质的不平衡力，致使转动力矩大，尤其是大口径阀门，依靠人力有时根本无法转动调节手柄；2、弹簧及阀门直径等设计不尽合理，致使启动压差、流量控制精度及工作压差范围等重要指标达不到使用要求；3、容易受到水锤撞击，噪声大，使用寿命较低。
发明内容
本发明要解决的技术问题是：为了提供一种结构简单、调节灵活方便、没有水锤撞击、没有噪音的双板式调节阀。
本发明解决其技术问题所采用的技术方案是：一种双板式调节阀，包括阀体、转轴、转板、定轴及弹簧，所述转轴固定在阀体内腔，转轴一端伸出阀体外，转轴包括外转轴及内转轴，所述外转轴套设在内转轴外，所述转板设置在阀体内腔，转板包括相对称的第一转板及第二转板，所述第一转板与外转轴固定连接，所述第二转板与内转轴固定连接，外转轴、内转轴可分别通过控制第一转板、第二转板的旋转以实现阀体内腔的开启或关闭，所述弹簧套设在内转轴上，弹簧包括上弹簧及下弹簧，所述上弹簧一端与内转轴固定连接，另一端与第二转板固定连接，所述下弹簧一端与外转轴连接，另一端与固定在阀体内的定轴固定连接。 
在本发明的一较佳实施例中，所述定轴与转轴相平行。 
在本发明的一较佳实施例中，所述上弹簧与下弹簧相抵靠。
本发明的有益效果是：本发明的双板式调节阀通过转轴及弹簧能够有效地控制转板的开合，控制灵活方便，不会有水锤撞击，也不会产生噪音，大大提高了阀门的使用寿命。 
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明双板式调节阀的结构示意图；
图中：1.内转轴，2.外转轴，3.第一转板，4.上弹簧，5.下弹簧，6.第二转板，7.阀体，8.定轴。 
具体实施方式
现在结合附图对本发明作进一步详细的说明。这些附图均为简化的示意图，仅以示意方式说明本发明的基本结构，因此其仅显示与本发明有关的构成。
如图1所示，一种双板式调节阀，包括阀体7、转轴、转板、定轴8及弹簧，所述转轴固定在阀体7内腔，转轴一端伸出阀体7外，转轴包括外转轴2及内转轴1，所述外转轴2套设在内转轴1外，所述转板设置在阀体7内腔，转板包括相对称的第一转板3及第二转板6，所述第一转板3与外转轴2固定连接，所述第二转板6与内转轴1固定连接，外转轴2、内转轴1可分别通过控制第一转板3、第二转板6的旋转以实现阀体7内腔的开启或关闭，所述弹簧套设在内转轴1上，弹簧包括上弹簧4及下弹簧5，上弹簧4与下弹簧5相抵靠，所述上弹簧4一端与内转轴1固定连接，另一端与第二转板6固定连接，所述下弹簧5一端与外转轴2连接，另一端与固定在阀体7内的定轴8固定连接。 
所述定轴8与转轴相平行，定轴8设置在转轴一侧，可以使下弹簧5产生较大扭矩。 
阀门在工作的时候，介质推开第一转板3及第二转板6，由于下弹簧5产生的扭矩M1通过第一转板3与外转轴2连接部位传递给外转轴2，扭矩方向为逆时针，与此同时，介质推动第二转板6形成另一个扭矩M2，通过上弹簧4传递给内转轴1，扭矩方向为顺时针，此时介质产生的扭矩与两弹簧产生的扭矩分别是相等的，如果我们需要对两转板的开启程度进行控制，那么我们就需要外加一个载荷，这个载荷形成扭矩M3与M4，分别作用在外转轴2和内转轴1上面，通过克服或者增加M1以及M2的大小实现双板开启程度的控制。
与现有技术相比，本发明的双板式调节阀通过转轴及弹簧能够有效地控制转板的开合，控制灵活方便，不会有水锤撞击，也不会产生噪音，大大提高了阀门的使用寿命。 
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
