Pneumatic ball valves in industrial applications is a widely used type of general-purpose valves, the use of large quantities, consumption is also fast, the need for regular and reasonable maintenance and repair, so that the efficiency can be improved, the cost can be saved, and reduce the time of maintenance. How to make the pneumatic ball valve longer service life, stable performance, the following points need to pay attention to the factors: 1, before using the pneumatic valve debris and iron filings with water for cleaning. 2, pneumatic valve in the closed state, the valve will also have some residual media, to cut off the power supply and gas source and then clean up, the pressure in the valve body to be completely released. 3, the valve will generally use sealing materials to prevent leakage and wear, the need for regular cleaning of sealing materials into. 4, flange nuts and bolts should be fixed tight, in order to prevent uneven acceptance between the flange surface leads to gasket damage or rupture, resulting in the valve flange docking out of the media leakage. 5, if the valve is a long-term open-air work will lead to the valve and parts of the rust may make the valve can not be used normally, so the need for maintenance and testing, in order to ensure the stable operation of the performance.
Pneumatic butterfly valve in the pipeline industry is familiar with a device system, how the quality of the product determines the quality of the project, so good quality pneumatic valve meets which requirements, performance when how to test it? Manufacturers in the production of engineering required specifications and models of valves, first of all, the product performance to authoritative testing to ensure product quality. Product quality testing: valve flow resistance coefficient testing: valve to go into the pipeline water. Valve opening and closing torque only valve in the normal operating pressure state, to ensure that the valve opening and closing times normal, close tight and continuity. Pre-shipment testing: internal pressure testing should be opened in the pneumatic valve operation
Dragon pneumatic butterfly valve product features: 1, the use of nylon pinless butterfly plate, with excellent wear reduction, self-lubricating, operating torque than ordinary pinned butterfly valve to reduce forty percent; 2, good abrasion resistance of the sealing surface (nylon abrasion resistance is seven times as much as copper), which can significantly extend the service life of the butterfly valve, and the service life can be significantly extended by a factor of three compared with the ordinary centerline butterfly valve; 3, nylon materials without any toxicity, and anti-bacterial, anti-mildew, in line with people's increasing attention to the requirements of the green environmental protection; 4, nylon has excellent alkali resistance, salt performance, resistance to erosion of weak acids, inert to organic compounds, wide range of adaptability; 5, the advanced pinless
How to well maintain the AT pneumatic actuator?1, AT pneumatic actuator and valve connection in accordance with ISO5211 standard, can be directly connected with the valve. It can also be connected with any valve through transition bracket and connector.2. The coaxiality of the pneumatic actuator and rotary shaft with the valve shaft must be ensured during installation.3. The inside of pipe joints and conduits should be cleaned and free from excesses, dust and grease, etc..4. For the connection of pneumatic actuators with solenoid valves, positioners, filters, pressure-reducing valves and so on, copper or nylon pipes can be used, and for the purpose of preventing dust and reducing noise, muffler or muffling throttle valve should be installed in the exhaust port.5. For dustproof and noise reduction, muffler or muffling throttle valve should be installed at the exhaust port. 5. Adjustment screw on pneumatic actuator
