The d671x pneumatic clamp butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switch, 90 ° reciprocating rotation, and small driving torque. It is used to cut off, connect, and regulate the medium in the pipeline, and has good fluid control characteristics and closing sealing performance,D671x Pneumatic Clamp Butterfly ValveHow to maintain it properly during use?
1、 Firstly, confirm whether there are any foreign objects in the clean pipeline. If there are foreign objects, they may damage the sealing surface of the valve and even hinder the operation of the valve core, ball or butterfly plate, making it impossible for the valve to close normally. It is necessary to clean all pipelines before installing valves. Confirm that there are no foreign objects inside the pipeline. Additionally, it is necessary to inspect the pipeline flange to ensure a smooth gasket surface. If the valve has a threaded connection end solenoid valve, a high-grade pipeline sealant should be applied to the male thread of the pipeline. Do not apply sealant on the female thread, as residual sealant on the female thread will be squeezed into the valve body. Excess sealant can cause blockage of the valve core or accumulation of foreign objects, resulting in the valve being unable to function properly.
2、 Check the d671x pneumatic clamp butterfly valve, which has been installed with damaged valves. Before installation, check and remove all transport stops, protective plugs, or covers on the surface of gaskets, and inspect the interior of the valve body to ensure that there are no foreign objects.
3、 The vast majority of control valves can be installed in any position, but the most commonly used method is to place the actuator vertically and at the top of the valve. If the actuator must be installed horizontally, consider adding an additional vertical support to the actuator. Ensure that the valve body is installed in such a way that the fluid flow direction is consistent with the direction indicated by the flow arrow or instruction manual.
4、 Ensure that there is sufficient space above and below the valve for inspection and maintenance. For valve bodies connected by flanges, ensure that the flange faces are accurately aligned to ensure even contact of the gasket table and prevent leakage.
The above is an introduction to the maintenance method of the d671x pneumatic clamp butterfly valve.
