The invention belongs to the technical field of sealing valves, in particular to a silent type fully closed horizontal pressure reducing valve, which comprises a transmission shaft arranged in the shell of the pressure reducing section, a bell valve spool arranged at the end of the transmission shaft, and a valve seat fixed to the shell of the pressure reducing section. The valve seat is characterized in that a pair is arranged outside the inner cavity of the shell of the pressure reducing section. A sealing combination is arranged at the end of the shell of the pressure reducing section and the end of the transmission shaft, and the end of the shell of the pressure reducing section is successively connected with a corrugated compensator, an axial sealing compensation adjustment combination and a silencing chamber, and the axial sealing compensation adjustment combination is connected with the valve seat. The invention adopts the axial adjustment of the opening degree of single valve instead of the original parallel adjustment structure of multiple butterfly valves, and the transmission shaft head is all sealed, so as to eliminate the defects of lax closure, internal leakage and inaccurate regulation, etc. fundamentally. A muffling chamber is arranged behind the valve, and the noise can be reduced by 20 DB-30 db.
【技术实现步骤摘要】
消音型全封闭卧式减压阀
本专利技术属于密封阀
,尤其是涉及一种消音型全封闭卧式减压阀。
技术介绍
减压阀作为一种常规工业用阀被广泛应用,在高炉煤气中,减压阀组被安装在高炉煤气进入煤气管网的位置,用于调节炉顶压力,以保证冶炼的正常操作,所以需承受炉顶压力,不得泄露。目前高炉煤气中减压阀组的结构均是用几个蝶阀组合通过调节开口度调节阀前后压差,这种结构普遍存在关闭不严,内泄外漏和调节不准确,及阀组出口风的噪音较大等弊病。
技术实现思路
本专利技术的目的是提供一种能够从根本上杜绝阀体关闭不严、内泄外漏、调节不准确和噪音较大等问题的消音型全封闭卧式减压阀。本专利技术的目的是通过下述技术方案来实现的:本专利技术的消音型全封闭卧式减压阀,包括设置在减压段壳体内部的传动轴,设置在此传动轴端头处的钟阀阀芯,与所述减压段壳体固定连接的阀座,其特征在于在所述减压段壳体内腔的外部设置有对中导向组合,在所述减压段壳体端部且位于所述传动轴端部设有密封组合,与所述减压段壳体端部依次连接有波纹补偿器、轴向密封补偿调整组合和消音室,所述的轴向密封补偿调整组合与所述的阀座相连接。所述的消音室为锥形开口的密封腔隔音室。所述的波纹补偿器内设有调节螺栓。本专利技术的优点:(1)本专利技术的消音型全封闭卧式减压阀采用单阀开口度轴向调节代替原有多个蝶阀并联调节结构,传动轴头全部密封,从根本上杜绝轴头外泄问题;(2)本专利技术的消音型全封闭卧式减压阀采用钟阀代替蝶阀及与阀座的对中装置,使密封更加可靠,避免了煤气泄漏和调节不准确等弊病;(3)本专利技术的消音型全封闭卧式减压阀在阀后设置了消音室,在煤气流 ...
