Requirements for the use of burner control valves

Control valve, with the help of power operation to change the medium flow, pressure, temperature, level and other process parameters of the final control element. Burner control valves often consist of an actuator and a valve. Follow our senior commissioning engineers to learn the requirements for the use of burner control valves.

Ensure the quality of control valves

The selection of control valves should be strictly calculated; the type, caliber, and performance should meet the requirements; the materials of various important parts of control valves should be strictly selected; they should have sufficient strength and stiffness; they should pass the pressure resistance test, gas tightness test, etc. in accordance with national standards; the manufacturing technology and testing methods of manufacturers must meet the standards, and they should be identified and approved by the competent authorities.

Ensure reliable operability

To prevent misoperation, the operator must pay attention to the notes marked on the nameplate: manufacturer's name, product model, rated flow coefficient, design bit number, product number and year of manufacture. The valve body should be cast or punched out to indicate the direction of media flow arrows and "DN" values and "PN" words and values, important valves are equipped with sufficient accessories, such as valve positioners, limit switches, etc.. There should be enough installation space and operation space, enough lighting, and strict operation procedures.

Have emergency devices

When an accident occurs in high-pressure gas equipment, in order to prevent direct damage to other equipment, a cut-off device must be installed in the pipeline connecting the equipment, and a quick cut-off valve if necessary. In the occasion of fire-prone, the fire resistance of the regulating valve should be considered from the structure, or with fireproof coating and other methods. Emergency devices are fireproof bags, but also the method of connecting rod protection, clamping elements can be used some fusible linkage, electro-thermal linkage, these rods are activated when heated, disconnected in the dangerous moment of fire, so that the valve moves to an insurance position.

The above is the requirements for the use of burner regulating valve, have you learned it? For more knowledge about burner regulating valve, welcome to visit the website of EBICOl https://cn.ebico.com/.
