How to choose the pressure reducing valve of the water bath vaporizer?
1. Clarify the use of the pressure reducing valve in the water bath vaporizer or device, and determine the working conditions of the valve: applicable medium, working pressure, working temperature, etc.
2. Determine the nominal diameter and connection method of the pipeline connected to the pressure reducing valve: flange, thread, welding, etc.
3. Determine the way to operate the pressure reducing valve: manual, electric, electromagnetic, pneumatic or hydraulic, electro-hydraulic linkage, etc.
4. According to the medium transported by the pipeline, working pressure and working temperature, determine the material of the shell and internal parts of the selected pressure reducing valve: cast steel, carbon steel, stainless steel, alloy steel, stainless acid-resistant steel, gray cast iron, malleable cast iron, Ductile iron, copper alloy, etc.
5. Select the type of pressure reducing valve; determine the type of pressure reducing valve.
6. Determine the parameters of the pressure reducing valve; for the automatic steam pressure reducing valve, first determine the allowable flow resistance, discharge capacity, back pressure, etc. according to different needs, and then determine the nominal diameter of the pipeline and the diameter of the valve seat hole.
The basis for choosing a water bath vaporizer pressure reducing valve:
1. The purpose, operating conditions and control mode of the selected pressure reducing valve.
2. The nature of the working medium: working pressure, working temperature, corrosion performance, whether it contains solid particles, whether the medium is harmful, whether it is flammable or explosive medium, the viscosity of the medium, etc.
3. Requirements for the fluid characteristics of the pressure reducing valve: flow resistance, discharge capacity, flow characteristics, sealing level, etc.
4. Requirements for the installation size and overall size of the pressure reducing valve: nominal diameter, connection method and connection size with the pipeline, overall size or weight limit, etc.
