SP429型小流量自力式微压调节阀.PDF

Instruction Manual Type SP429 阀在大多数工况中执行器膜室可完全承受阀前最高使用压力而不会损坏。 Overload SafetyTo reduce the influence of the parts gravity for control pressure. The whole regulating device of the pressure regulating valve should be designed as light and precise as far as possible. The downstream pressure is very low during normal operation. The force on the regulating device is very small. The overload is unavoidable in actual operation. The downstream pressure can reach the upstream pressure at abnormal state. At this time, the push force generated by the diaphragm assembly is very destructive to the regulation device. The overload device of the pressure regulating valve can effectively uninstall the overload force and avoid damage to the regulation device. Namely when the pressure regulating valve is operating. In most case, the diaghragm case of the actuator can fully withstand the maximum operation pressure of upstream and it will not be damaged. 调压方便螺杆式调节机构使调压更轻松，方便，迅速。 Easy Pressure RegulationThe screw regulation device can realize easy, convenient and quick pressure regulation. 软密封阀芯为软密封结构，在阀芯关闭时能轻松切断流体。 Soft SealingThe valve plug designed as soft sealing structure and can easily shut off the flow. 不锈钢执行器执行器作为调压阀的重要部件，采用不锈钢板成形 ，有很高的耐压强度和使用寿命。 Stainless ActuatorAs an important part of the reguator, the actuator is made of stainless plate to ensure its high pressure-strength and long service life. 安装方便 门出厂时无法预估现场管线走向和安装空间 ，安装后经常会发现由于周边设备的影 响使调压阀的调校 ，观察很不方便，SP429调压阀的执行器连同调节机构可在不解体状态下做360度旋 转 ，且调整后不影响其原有的性能参数。 Easy InstallationThe direction of pipeline and installation space can not be estimated when the valve is outputted. It is not convenient to calibrate and watch the pressure regulating valve due to influences from the surrounding devices after installation. The actuator and regulation device of the SP429 pressur
