Seven, tight metal sealing butterfly valve product uncomfortable or installed on the end of the line, such as must be installed in the end of the pipe, fittings export flange, should also be taken to avoid the backlog of tightly closed circle, too. 3, installed in the pipeline position, the best location for the vertical loading, but you can't flip. 4, apply needs to adjust flow, has the worm gear box of stem. 。 2, disc plate installation of flange suggested that a set of suitable and use disc valve, namely HGJ54 - The type 91 socket welding steel flange. 3, electric drive disc valve factory has will curb institutions opening and closing of the trip. 6, seizing the connection parts required pressure, namely guarantee packing tightly closed, but also guarantee the valve stem flexible rotation. 2, pneumatic butterfly valve factory is through strict investigation and experiment, but there are also individual products in transit semi-automatic screw dislocation, need new debugging, pneumatic, hydraulic, etc. , please read the form a set of device drivers use descriptive text. 8, install use echo regularly seizing the valve stem effect, find fault out early. Q: a: the common failures pneumatic butterfly valve, pneumatic butterfly valve to debug 1, butterfly either manual, pneumatic, hydraulic and electric devices before the factory after strict debugging, the user when the re-inspection tightly closed performance, on both sides of the import should be fixed on average, close the disc valve, pressure on inlet side Marine valve, in the export side carefully check whether leakage phenomenon, in pipeline strength before the trial, disc plate should be open and avoid destroying tightly closed. To avoid power on is the direction to make wrong, the user first, after turning on the power supply first, open the manual to half open position, in according to the electric switch seizing orders set direction can be exactly the same direction with the valve closed. 2, pneumatic butterfly valve of the common faults and alleviation measures 1, before installation way can recognize this factory product quality, and the character and the medium flow arrow is consistent with the working condition of yun xing, and the body will wash clean, not allowed in tightly closed circle and butterfly plate with foreign impurities, before cleaning is not allowed to close the butterfly plate, lest destroy tightly closed circle. 5, back to the opening and closing more disc valve, in 2 months time, open the worm gear case cover, seizing ghee is normal, should maintain the appropriate number of trades. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
