The utility model has the advantages of easy fabrication, simple structure, large pressure reduction ratio, good tightness, no leakage and high sensitivity.
【技术实现步骤摘要】
本技术涉及一种高灵敏度可调式减压阀,属于阀门领域。
技术介绍
现有技术的减压阔基本上有两种,一种是将来自进口的介质流经主阀的阀芯和先导阀的阀椎通过弹簧受压大小打开主阀芯下的主阀口的开度大小使压力稳定的方式来调节压力,另 一 种是使高压介质流入带有活塞、膜片和主副阀瓣的阀的进口,通过介质作用在这些部件上面积不同所构成的 压力差和弹簧立的平衡关系,调节阀瓣开口大小,来调节压力。但是这些阀的阔杆和阀瓣基本上为一体,制造困难,结构复杂,灵敏度差,减压比小,阀瓣顶端为弧形或突起,密封差,容易造成泄漏,而且容易堵塞。
技术实现思路
为了克服现有的减压阀制造困难,结构复杂,灵敏度差,减压比小,密封差,容易造成泄漏,而且容易堵塞的不足,本技术的目的在于提供一种制造容易,结构简单,减压比大,密封性好,不容易泄漏的高灵敏度可调式减压阀。本技术解决其技术问题所采用的技术方案如下高灵敏度可调式减压阀,包括压盖、圆柱螺旋压縮弹簧、阀体、阀瓣、阀杆、压杆、膜片、下托盘、顶盖、调节弹簧、压板、限位螺帽,压盖位于阀体底端,与阀体嵌套,固定连接,阀瓣的底端嵌套在底盖的空腔顶端,阀杆和压杆连接为一体,穿过阀体中心,阀杆底端与阀瓣连接,压杆顶端与膜片接触,圆柱螺旋压縮弹簧位于阀瓣和底盖形成的空腔内,顶盖位于阀体顶端,顶盖内有空腔,调节弹簧位于空腔内,压板位于调节弹簧和顶盖之间,下托盘位于顶盖底端,与调节弹簧接触,膜片位于压杆顶端和下托盘底面之间。还包括安全帽,安全帽嵌套在顶盖顶端。还包括调节螺钉,调节螺钉位于安全帽内的空腔中,穿透顶盖顶端,与压板接触。还包括限位螺帽,限位螺帽嵌套在调节螺钉上,位于顶 ...
