稳压稳流阀
本专利技术涉及一种稳压结构,具体涉及一种稳压稳流阀。
技术介绍
流体管路中一般希望流体压力、流量都较稳定,现在技术要实现这一目标则需要的配置较为复杂。
技术实现思路
本专利技术针对现有技术的不足,提出一种通过简单结构就能稳定管路压力、流量的稳压稳流阀。本专利技术通过下述技术方案实现技术目标。稳压稳流阀,其改进之处在于:包括壳体、膜片、气门、阀座、下弹簧、上弹簧;所述膜片平置在壳体内腔中,膜片外壁与壳体内腔间隙配合,将壳体内腔隔成上、下腔;所述阀座设置在壳体内腔下腔中,阀座上设有中心轴线竖置、上下贯通的阀座孔,阀座孔下部设有大端朝下的锥孔;所述气门包括阀体、阀体上方的顶杆,所述气门阀体为与阀座阀座孔下部锥孔相对应的锥体;所述气门顶杆贯穿阀座阀座孔;所述上弹簧设置在膜片上端面与壳体内腔上端面之间;所述下弹簧设置在气门下方,将气门向上顶,使气门顶杆上端面与膜片下端面保持接触;所述阀座阀座孔的侧壁设有与阀座阀座孔相通的径向通孔,阀座径向通孔通过侧支路与壳体内腔上腔连通;所述壳体下部设有与壳体内腔下腔连通的进口端,壳体上部设有与壳体内腔上腔连通的出口端;所述侧支路中设有使气流只能从阀座径向通孔流向壳体内腔上腔的单向阀。上述结构中,所述侧支路中设有流量调节阀、流量剂。本专利技术与现有技术相比,具有以下积极效果:1、本专利技术设有气门、阀座,气门阀体与阀座阀座孔下部锥孔之间的间隙,控制进气管路的流量。膜片上方设有上弹簧,气门下方设有下弹簧,阀座阀座孔的侧壁设有与阀座阀座孔相通的径向通孔,阀座径向通孔通过侧支路与壳体内腔上腔连通;稳压稳流阀设有与壳体内腔下腔连通的 ...
