Installation and Commissioning of Regulating Valve

With the progress of science and technology, the production process automation to control the flow of fluid control valve has been widely used in various industries. For thermal, chemical control system, control valve as the ultimate medium of the quality control process and safety indexes, plays an important role in the stable production, optimal control, maintenance and repair cost control. In the application of the control valve, the calculation and selection is the prerequisite, installation and commissioning is the key, use and maintenance is the purpose. If the sanitary check valve is not installed properly, or debugging is not good, it can not play the role of regulation, and even become a system of drag.

Basic principles of installation
The installation of the control valve should comply with the relevant national standards, in strict accordance with the design drawings and design documents. For example, construction and installation engineering quality inspection and evaluation standards, industrial construction and acceptance of automation, electrical equipment installation engineering construction and acceptance specification; comply with relevant provisions of applicable national standards required for the installation of equipment, auxiliary equipment and materials should be the main material.

Regulating valve and accessories from the factory to the installation before, all kinds of impact of random vibration and handling in transit vehicles, and during transportation and storage, environmental temperature and humidity changes, which can result in the performance of control valve and accessories change. Therefore, it is necessary to carry out part of the performance test before installation.

Sanitary regulating valve is installed before the test include the following: appearance, static characteristics, leakage, load the whole journey time, compressive strength, insulation performance, air tightness and sealing and so on, of which the first 5 will check for the project.

Of course, there are some requirements for the inspection site. For example: the requirement of environmental temperature at 10 ~ 35 DEGC; air relative humidity is less than 75%; the venue has sufficient space and adequate lighting or lighting conditions; around the local oscillator can not have sharp and strong magnetic field interference; power supply, gas supply to meet the requirements.
