Description

立式高压天然气疏水阀
所属技术领域
本发明涉及一种高压天然气疏水阀，尤其是用于天然气采集、加压、输送的汽液分离的高压疏水阀。
背景技术
目前，市场上普遍使用的高压天然气疏水阀，经常出现杠杆浮球扁了，杠杆浮球抗压力不够，无法使高压杠杆浮球正常工作。为了提高杠杆浮球浮力，用网袋捆了很多小浮球，各种情况都见过。
发明内容
为了解决杠杆浮球浮力小，抗压强度差的难题，本发明公开了一种立式高压天然气疏水阀，其特征是根据阀体的直径空间，把浮球尽量做大，在杠杆浮球内焊上环形板条加强筋和连接管加强筋，提高杠杆浮球的浮力和抗压强度，在有限的空间里，经过三级杠杆转换，把浮球的行程转换在阀体的中轴线上，节省空间，提高杠杆浮球的临界开启力。

具体实施方式
下面结合附图和实施例对本发明进一步说明。如图所示，立式高压天然气疏水阀主要是由上阀体(1)天然气混合液入口(2)压力表接口(3)平衡管口(4)天然气出口(5)螺母(6)杠杆浮球(7)浮球连接杆(8)环形板条加强筋(9)杠杆2(10)轴销3(11)连接板1(12)轴销2(13)杠杆1(14)阀芯(15)陶瓷珠(16)阀座法兰(17)陶瓷阀座(18)O型橡胶圈(19)凝结水出口(20)法兰垫(21)阀座套(22)排污堵头(23)阀座连接法兰(24轴销1(25)杠杆支架1(26)杠杆支架2(27)轴销4(28)轴销5(29)轴销8(30)连接板2(31)轴销6(32)轴销7(33)下阀体(34)杠杆3(35)法兰垫(36)螺栓/螺母(37)浮球连接管(38)共同组成。该疏水阀主要特征是根据阀体(1)的直径空间把杠杆浮球(7)尽量做大，在杠杆浮球(7)内焊上环形板条加强筋(9)和浮球连接管(38)加强筋，提高杠杆浮球(7)的浮力和抗压强度，在有限的空间里，经过三级杠杆转换把杠杆浮球(7)的行程转换在阀体(1)的中轴线上，节省空间，提高杠杆浮球(7)的临界开启力。
当天然气混合液进入时，天然气上升，经平衡管口(4)回流，凝结水不断进入，凝结水液位上升，杠杆浮球(7)随液位上浮，带动三级转换杠杆开启疏水阀芯陶瓷珠(16)，凝结水靠压差经陶瓷阀座(18)由凝液出口排出。当凝结水停止进入时，杠杆浮球(7)随液位升降调节疏水阀工作。该疏水阀结构紧凑，杠杆浮球浮力大，抗压强度高，疏水量大，工作性能稳定，能满足各种工况的高压天然气疏水阀要求。
