Description

放气安全阀
技术领域
本实用新型涉及液压隔膜计量泵部件,具体涉及放气安全阀。
背景技术
在目前国内众多的液压隔膜计量泵中,安全阀、放气阀是确保液压隔膜计量泵安全工作必不可少的组成部件之一。当液压腔压力超过规定的允许压力时,安全阀可迅速打开,排出部分液压油,起到保护整个***的作用;而放气阀具有将柱塞工作时带入液压腔的气体排出腔体。目前的安全阀、放气阀为分别独立的阀,使得液压隔膜计量泵结构复杂,生产成本高。
实用新型内容
为克服现有技术中存在的问题,本实用新型旨在提供一种将安全阀、放气阀功能合二为一的安全放气阀。
所述的放气安全阀,包括阀体,阀体底部配合设有阀座,阀座分别设置轴向通孔、径向通孔,阀体腔内设有安全阀芯,安全阀芯上套设有导杆,该导杆上设有弹簧座及相应的安全弹簧,阀体顶部设有调节螺母,安全阀芯腔内配合设置放气阀芯、放气阀簧和阀球。
所述的放气安全阀,其放气阀芯下方设置间隙调整垫及挡圈。
所述的放气安全阀,其阀体的上端面设有锁紧螺母。
所述的放气安全阀,其调节螺母顶端设置示窗。
所述的放气安全阀,结构设计巧妙,结构精简,将安全阀、放气阀功能合二为一,大大精简了液压隔膜计量泵的结构,缩小了体积,降低了生产成本,同时提高了安全阀的控制性能。
附图说明
图1为本实用新型一较佳实施例的纵向剖视结构示意图。
具体实施方式
现结合,详细说明本实用新型的一较佳实施例。
图1所示的放气安全阀,包括阀体5,阀体5外侧配合设置上O型密封圈12,阀体5底部配合设有阀座1,阀座1底端设有下O型密封圈16,阀座1分别设置轴向通孔18、径向通孔15,阀体5腔内设有安全阀芯2,安全阀芯2上套设有导杆4,导杆4与安全阀芯2之间设有球垫3,该导杆4上设有弹簧座9及相应的安全弹簧11,阀体5的上端面设有锁紧螺母6,阀体5顶部设有调节螺母7,用于调节安全弹簧11的压缩强度,调节螺母7顶端设置示窗8,用于查看放气安全阀的内部情况,安全阀芯2腔内配合设置放气阀芯14、放气阀簧13和阀球10,放气阀芯14下方设置间隙调整垫19及挡圈17,放气阀芯14的开启高度可由间隙调整垫17及挡圈19来调节。
所述的放气安全阀的工作过程:当液压隔膜计量泵***油压超过安全阀芯2上的安全弹簧11的压紧力时,油液通过轴向通孔18将安全阀芯2顶起,从而,油液能够经径向通孔15流出,卸荷***油压,起到保护整个***的作用;由于液压隔膜计量泵的油压是随柱塞往复运动而产生脉动的,在柱塞吸液过程中,放气阀芯14被放气阀簧13推开,此时,存在油腔内的气体顺着放气阀芯被推的间隙缝排出,并顶开阀球10排出泵外;而当柱塞排液时,因油腔压力逐渐增大,放气阀芯14压紧放气阀簧13,关闭排气。
