The invention relates to a large caliber air valve, which is used for opening and closing waste gas in the waste gas treatment and emission system. Large caliber air valve, including valve box and valve plate, valve gate through the valve box; the valve plate on skid; valve plate connected with the operating lever; wherein the valve plate is composed of a main valve plate and the auxiliary valve plate; the valve plate and the main valve plate side pin is connected through a connecting rod; operating lever the valve plate is connected with the vice. The door has a valve closing process secondary valve plate drives the connecting rod pin of the connecting rod around the main valve plate on the rotation of the pin to push the main valve plate to the valve frame (or seal plate) positive pressure applied several times in the operating force between the valve frame and the main valve plate tight sealing, high reliability; implementation of operation the equipment has the advantages of small volume, low power; open the valve operating force gate valve plate along the rail traction side movement, the connecting rod rotates, the valve plate thickness is less than the valve box (or sealing plate) and the distance between the slide rails, thereby opening the valve has the advantages of small resistance etc..
【技术实现步骤摘要】
大口径风阀
本专利技术涉及大口径风阀,应用于废气治理及排放系统中打开或关闭废气。
技术介绍
大通风量的阀门需要大口径。大口径的阀门要保证密封性,密封面上的弹性体需要有足够的正压力以得到足够的压缩量。现行风阀包括阀门框及阀板,不足是开启阀门的操作力要求很大,用于实现操作力的设备体积和功率都要求很大。
技术实现思路
本专利技术的目的是提供一种开启阀门操作力小的大口径风阀。本专利技术的技术方案是:(a)大口径风阀,包括阀门框和阀板,阀门口穿过阀门框;阀板位于滑轨上;阀板与操作杆相连;其特征是所述阀板由主阀板和副阀板组成;主阀板和副阀板通过连杆销轴相连接;操作杆与副阀板相连。(b)a所述的大口径风阀,其特征是阀门框和阀板之间装有密封板。(c)a或b所述的大口径风阀,其特征是连杆销轴至少有两组。(d)c所述的大口径风阀,其特征是每组连接销轴位于主阀板(3)和副阀板(9)的两个侧面上。(e)a、b或d所述的大口径风阀,其特征是操作杆(13)为液压缸活塞杆、气压缸活塞杆、机械连杆、机械杆、螺杆五者之一。(f)a、b或d所述的大口径风阀,其特征是操作杆(13)与气动、电动或手动的机械力作直线运动的输出轴相连。(g)b所述的大口径风阀,其特征是密封板(2)为弹性材料。(h)g所述的大口径风阀,其特征是弹性材料为耐油橡胶板或耐腐的硅胶板或弹性金属材料。本专利技术具有如下优点:1、当阀板在滑轨上运动到阀门口时,主阀板与阀门框(或密封板)相叠合将阀门口关闭,并因静摩擦力的作用主阀板停止运动;此时,副阀板继续运动并带动连杆销轴各连杆绕着主阀板上的销轴转动推动主阀板向阀门框(或密封板)施 ...
