Bellows gate Industrial Valves stem is opened or closed travel relatively short, and it is very reliable detection function, and due to changes in his seat and disc stroke proportional relation, very suitable for the flow of control. Therefore, this type of valve is very suitable for block or toning and save as to apply. 1, all kinds of manual valve device on the thermal insulation pipe, handle shall be down. 2, installation location, altitude, direction of import and export is necessary to conform to the requirements of the planning, tight connection should be strong. 3, corrugated pipe gate Industrial Valves device is necessary before the appearance inspection, the valve nameplate should be consistent with existing national standards 'universal signal Industrial Valves GB12220 rules. For the working pressure is greater than 1. 0 mpa and block effect on backbone pipe valves, before the device should be strength and tight function experiment, qualified rear must use. Strength experiment, experiment pressure for the nominal pressure of 1. 5 times, duration of not less than 5 min, shell and packing shall be no leakage of valve shall be qualified. Rigor experiment, experiment pressure for the nominal pressure of 1. 1 times; Pressure in the duration of the experiment should conform to the requirements of the standard GB50243, with no leakage for qualified for valve sealing surface.
