1. Equipment for regulating valves
1.1 Basic principles of equipment
The equipment of the regulating valve shall comply with the relevant national standards and be strictly implemented in accordance with the planning drawings and planning documents. For example, construction equipment engineering quality inspection and appraisal standards, industrial automation appearance construction and inspection standards, electrical equipment and equipment construction and inspection standards, etc.; equipment, auxiliary equipment and primary materials required for equipment should comply with the relevant provisions of the current national standards.
1.2 Inspection before equipment
Valves and accessories manufactured by Valve Manufacturing Co., Ltd. are subjected to random vibrations caused by transportation tools during transportation and various shocks during loading and unloading, as well as environmental temperature during transportation and storage. Changes in humidity, etc., may change the function of the regulating valve and accessories. Therefore, it is necessary to perform a partial function check in front of the device.
The inspection before the regulating valve equipment mainly includes the following contents: appearance, static characteristics, leakage, no-load full stroke time, pressure resistance, insulation function, air tightness and sealing, etc. The first five items are required items. Of course, there are also certain requirements for the place to be inspected. For example: the ambient temperature is required to be 10 to 35 ° C; the relative humidity of the air is not more than 75%; the field has enough space, and the light is sufficient or there are lighting conditions; there is no strong vibration source and strong magnetic field disturbance around; the power source and the gas source are in accordance with Request and so on.
1.3 Equipment attention matters
For the valve control equipment, it is necessary to ensure safety, ensure the use of functions, easy operation and maintenance, and save equipment costs. Here are some specific questions about the needs of the equipment for these four points.
