Electric valve manufacturers: Matters needing attention in the assembly of electric gate valve
For the automatic control system that has been designed and installed, before using the new valve, check whether the factory nameplate in the valve meets the design points. The electric gate valve can ensure the normal operation of the regulating valve during operation and ensure the safe operation. The following new items should also be adjusted.
1. Basic error limit; Full trip arrangement error; Backward; Blind area; Leakage (under strict management).
2. If the pressure regulating valve in the system is maintained, in addition to the above new items, the tightness of the stuffing box and the connection of the old valve should be checked.
When used on site, many of them are not caused by the product quality problems of the pressure regulating valve itself, but because the assembly of the pressure regulating valve is unreasonable, such as the use environment, the assembly position and direction are unreasonable, or the pipeline stains. Therefore, the installation and application of electric control valve should pay attention to the following aspects:
⑴ The regulating valve is an on-site instrument with a working temperature within the range of -25-60 ℃ and an air humidity ≤ 95%. If installed in the outdoor or high heat site, to take moisture and refrigeration countermeasures.
(2) regulating valve should generally be vertical assembly, the case can be tilted assembly.
(3) assembly control valve pipe spacing road or ground can not be too high. When the relative height of the pipeline exceeds 2m, the service platform should be set as much as possible, which is conducive to the operation and maintenance of the spindle.
④ Before assembling the regulating valve, the pipeline should be cleaned to remove stains and welding scars. During installation, in order to ensure that there is no impurity residue in the valve body, the valve should be cleaned again, and all valves should be opened when introducing substances to avoid residue adhesion. After applying the spindle organization, return to the original neutral position. If you want to process again when the regulating valve fails or is repaired, the regulating valve should be provided with a bypass pipe, and you need to pay attention to whether the installation method of the regulating valve meets the conditions of the whole process.
(6) electric control valve part of the installation of electrical equipment must comply with the relevant power distribution equipment construction standards. For explosion-proof equipment, assembly shall be carried out in accordance with the Code for Installation of Electrical Equipment in Explosion Hazardous Places. During the operation and maintenance, it is forbidden to open the bottle cap, repair or pry up the explosion-proof surface layer at the explosive position. At the same time, do not knock or scratch the explosion-proof surface layer during disassembly and assembly, and restore the original explosion-proof condition after maintenance.
