故障现象 The breakdown phenomenon |
产生原因Cause reason | 排除方法remove the method |
阀后压力不稳定随着阀前压力变动而变动 After the valve the pressure does not stabilize along with the valve in front of the pressure oscillation but changes |
1、阀芯被异物卡住 2、阀杆、推杆卡住 3、进液管道堵塞 1 valve core is caught by the foreign matter 2 valve lever, the throw out lever catches 3 enters the fluid pipeline to stop up |
1、重新拆装排除异物 2、重新调整 3、疏通 1 redisassembles and assembles removes the foreign matter 2 readjusts 3 dredges |
阀后压力降不下来,始终在需求值上方变动 After the valve the pressure does not get down, in needs above the evaluation to change throughout |
1、设定弹簧刚度太大 2、阀口径过大 3、阀前压力过高,减压比过大 1 establishes spring steel too to be big 2 valves calibers oversized 3 valves the pressure excessively is high, reduced pressure compared to oversized |
1、更换弹簧 2、更换较小口径 3、阀前压:阀后压超过10:1应2级降压 1 replaces the spring 2 replacements compares the small caliber 3 in front of valves: After the valve the pressure surpasses 10:1 should levels fall the pressure |
阀后压力升不上去,始终在需求之下方变动 After the valve the pressure con not rise, in needs underneath the evaluation to change throughout |
1、设定弹簧刚度太小 2、阀口径过小 3、减压比过小 1 establishes spring steel too to be small 2 valves calibers excessively are small reduced pressure excessively are smaller than |
1、更换弹簧 2、更换较大口径 3、阀前压:阀后压低于1:25,应提高阀前压 1 replaces the spring 2 replacements heave-caliber 3 in front of valves presses: After the valve pulls down in 1:25 should enhance in front of valve to press |
阀前压力升不下来,始终在需求值下方变动 After the valve the pressure con not rise, in needs underneath the evaluation to act throughout |
1、设定弹簧刚度太小 2、阀芯被异物卡住 3、阀杆、推杆卡住 4、阀芯、阀座损坏、泄漏量过大 5、阀口径太大 1 establishes spring steel too to be small 2 valve cores are caught by the foreign matter 3 valve lever, the throw out lever catches 4 valve core, valve seat damage, spillage oversized 5 valves calibers oversized |
1、更换弹簧 2、重新拆装 3、重新调整 4、重新研磨或更换 5、更换较小口径 1 replaces the spring 2 redisassembles and assembles 3 readjusts 4 regrinds or the replacement 5 replacements compares the small caliber |
阀前压力降不下去,始终在需求值上方变动 After the valve the pressure con not rise, in needs above the evaluation to act throughout |
1、设定弹簧刚度太大 2、阀口径过小 3、阀芯、阀杆、推杆卡住 1 establishes spring steel too to be big 2 valves calibers excessively are small 3 valve core, valve lever, deactivation and so throw out lever |
1、更换弹簧 2、更换较大口径 3、排除卡死原因,重新调整 1 replaces the spring 2 replacements heave-caliber 3 removes the deactivation reason, readjusts |
阀后压或阀前压波动过于频繁 After the valve the presses or in front of the presses the undulation too to be frequent |
1、阀口径过大 2、执行机构膜室容量太小 1 valve caliber oversized 2 implementing agencies membrane room capacity too is small |
1、选择恰当的阀口径 2、在进液口管道内增设阻尼器 1 choice appropriate valve caliber 2 in enters in the fluid pipeline to additionally build the attenuator |
