Electric transmission disc valve troubleshooting methods

Recently, (electric transmission disc valve) has the factory control mechanism Kai, closed stroke adjusted. To prevent the power is turned on the wrong direction, the user first connected to the power, the first open manually to the semi-open position. Pneumatic adjustment Two-way full-flow threaded ball valve DN50, ball valve test and debugging and common troubleshooting methods: Description: First, the installation of test and adjustment: 1, this product, whether manual, pneumatic, hydraulic, electric components are After rigorous commissioning, the user should check the sealing performance of the inlet and outlet evenly, close the valve disc, exert pressure on the inlet side and observe whether there is leakage on the outlet side. Before conducting strength test on the pipe, Plate open to prevent damage to the secondary air compressor safety valve, spring-loaded safety valve, micro-Kai safety valve, stainless steel safety valve, steam safety valve, power station safety valve. 2, Although the products are strictly inspected and tested before leaving the factory, there are also some screwdrivers on the way of transportation. To readjust, pneumatic, hydraulic and so on, please read the instruction manual of the drive unit. 3, (electric transmission disc valve) has been the factory control mechanism Kai, closed stroke adjusted. To prevent the power is turned on the wrong direction, the user first turn on the power, the first open manually to the semi-open position, press the electric switch to check the direction of the disc and valve closing direction can be consistent. Second, the common pneumatic ball valve failure and elimination methods 1, the installation front road to confirm the performance of our products and media flow arrow is consistent with the movement conditions, and plug the valve cavity clean, not allowed in the ring and the ball are attached There are foreign bodies, not clean before the ball must not be closed to avoid damage to the ring. 2, the flange plate supporting the installation of special disc flange recommended, that is HGJ54-91 socket welded steel flange. 3, installed in the pipeline location, the best position for the legislation, but can not flip. 4, the need to regulate the use of traffic, a worm gearbox control. 5, the number of open, close the ball valve, in about two months time, open the worm gear box cover, check the butter is normal, should maintain the right amount of butter. 6, check the connection parts require compression, that is, to ensure that the filler bees sex, but also to ensure flexible stem rotation. 7, metal seal ball valve is different from the pneumatic ball valve products are not suitable for installation at the end of the pipeline, such as must be installed at the end of the pipeline, the need to take the export package hair blue, to prevent the backlog seals, over.
