corrugated pipe cut-off valve before installation should be adjusted to be put into use, so you know how to adjust the corrugated pipe cut-off valve is! ! ! ! What matters need attention and adjust?

opening pressure adjustment

, corrugated pipe cut-off Industrial Valves before shipment should be by Taiwan to adjust its opening pressure to the setting value of the user requirements. If users spring pressure level, the general should be adjusted by the lower limit of pressure level of the factory.

the user in the corrugated pipe cut-off Industrial Valves installed to the protected equipment before or before installing, adjustment must be installed in the scene, to ensure the setting of bellows globe valve pressure value meets the requirements.

indicated on the nameplate of the spring within the scope of work stress level, by rotating adjustment screw to change the spring compression, the opening pressure can be regulated.

before rotating adjusting screw, should make the Industrial Valves inlet pressure is reduced to below 90%, opening pressure to prevent rotation adjustment screw when the disc is driven to rotate, so that damage the sealing surface.

to guarantee the accuracy of the opening pressure value, should be adjusted when the medium conditions, such as the type of medium, and the liquid temperature as close as possible to the actual operating conditions. Medium type change, especially when the accumulated state of the medium is not at the same time, Example

if from liquid to gas phase) , the opening pressure often change. Working temperature

when opening pressure generally reduced. Reason at room temperature adjustment and used in high temperature, the temperature of the set pressure value should be slightly higher than the requirements of opening pressure values. To what extent with the valve structure and material choose

has relationship with, should be according to manufacturer's instructions.

conventional corrugated pipe cut-off valve for fixed additional back-pressure occasions, when opening pressure adjustment after the inspection, The back pressure to atmospheric pressure) , the setting value shall be the requirements of opening pressure value minus the superimposed back pressure.
