Abstract

本发明公布一种减少汽蚀、降低噪声的新型流量调节阀。阀体内安装有阀座，阀体上还连接有出口法兰和进口法兰；所述阀体内安装有芯杆组件和阀盖；所述阀座上开有与芯杆组件配合的节流孔，节流孔与芯杆组件配合的一端是外宽内窄的圆锥形；所述芯杆组件包括芯杆和固定在芯杆端部的阀芯；所述阀芯包括均匀固定在芯杆端部的多个弧形叶片，多个弧形叶片的下端面为与节流孔端面配合的圆锥形；多个弧形叶片朝同侧弯曲，相邻弧形叶片之间留有间隙。由于流体是从弧形叶片间的月牙形缝隙中流出来，相对于传统阀利用单一环形缝隙调节流量，其能够减少汽蚀产生，降低噪音。所以，与现有技术相比，本发明具有噪声低、结构简单、不易磨损、易调节控制等优点。

Description

一种新型流量调节阀
技术领域
本发明涉及一种控制阀，具体是一种减少汽蚀、降低噪声的新型流量调节阀。
背景技术
调节阀是工业管道输运装置中重要的设备。调节阀是通过执行机构推杆的位移，改变调节阀的节流面积，达到调节的目的，同时它也是噪声的主要发生源。噪声污染已经成为世界公认的4大污染源之一，各国都投入巨资治理噪声，人们对噪声控制提出了更高的要求。调节阀常常是管路系统中的噪声源，当压差增大，流速增加，压力降低，当压力降到一定临界值时，容易引起气穴、气蚀现象，并伴有流体噪声和振动。调节阀流道结构是影响调节阀产生噪声的关键因素；因此，对调节阀结构的研究是很有必要的。
发明内容
为了克服上述现有技术的缺点，本发明提供一种新型流量调节阀。
本发明是以如下技术方案实现的：一种新型流量调节阀，包括阀体，阀体内安装有阀座，阀体上还连接有出口法兰和进口法兰；所述阀体内安装有芯杆组件和阀盖；所述阀座上开有与芯杆组件配合的节流孔，节流孔与芯杆组件配合的一端是外宽内窄的圆锥形；所述芯杆组件包括芯杆和固定在芯杆端部的阀芯；所述阀芯包括均匀固定在芯杆端部的多个弧形叶片，多个弧形叶片的下端面为与节流孔端面配合的圆锥形；多个弧形叶片朝同侧弯曲，相邻弧形叶片之间留有间隙。
其进一步是：所述多个弧形叶片的上端面呈外宽内窄的圆锥形。
阀芯在插入阀座的圆锥形的节流孔的过程中，弧形的月牙形缝隙逐渐变小，直至完全闭合，通流量有大变小，实现流量调节作用；同样，阀芯从阀座中离开过程中，弧形叶片间的月牙形缝隙由小变大，流量也由小变大，实现流量调节。
由于流体是从弧形叶片间的月牙形缝隙中流出来，相对于传统阀利用单一环形缝隙调节流量，其能够减少汽蚀产生，降低噪音。所以，与现有技术相比，本发明具有噪声低、结构简单、不易磨损、易调节控制等优点。

具体实施方式
以下是本发明的一个具体实施例，现结合附图对本发明做进一步说明。
如图1至图4所示，一种新型流量调节阀，阀体1下部分呈圆形，上部分呈扁圆形；在阀体1内中部部位安装有阀座1-1，阀座1.1上开有与芯杆组件3配合的节流孔，节流孔与上端是外宽内窄的圆锥形。在阀体1下部分上连接有进口法兰1-3，阀体1上部分上连接有出口法兰1-2。阀盖2安装在阀体1上端。芯杆组件3包括芯杆3-1和固定在芯杆3-1端部的阀芯3-2，芯杆3-1穿过阀盖2，阀芯3-2与节流孔相对布置；阀芯3-2包括均匀固定在芯杆3-1端部的具有弹性的多个弧形叶片，多个弧形叶片的下端面为与节流孔端面配合的圆锥形；多个弧形叶片朝同侧弯曲，相邻弧形叶片之间留有间隙。多个弧形叶片的上端面呈外宽内窄的圆锥形，以便提高弧形叶片的弹性和通油稳定性。
工作过程：
将出口法兰1-2和进口法兰1-3与输运管道主体连接固定一起；通过推拉芯杆3-1带动阀芯3-2进出阀座1-1的圆锥形的节流孔；当推动芯杆3-1使阀芯3-2进入阀座1-1的圆锥形的节流孔时，阀芯3-2弧形叶片构成的月牙缝隙逐渐缩小，流量也逐渐缩小；当推动芯杆3-1时，阀芯3-2退出阀座1-1的圆锥形的节流孔，该过程中的阀芯3-2弧形叶片构成的月牙缝隙逐渐增大，流量也逐渐增大；实现流量调节作用。
