Seat production processing
In order to achieve good product quality,every step of production goes through strict procedures.Take ball valve seat for example,The production process is as follows：
- Roughing Machining
- Heat treatment
- Finishing Machining
- Drilling
- Pressure seal ring
- Polishing
1.Roughing Machining
In the Rough machining production process,we could detect some situations timely,such as the defects in blank material,or material margin is in sufficient and so on.Then it is convenient for us to repair or scrap raw materials in a timely manner;
2.Heat treatment
In the heating processing,it could improve the mechanical properties of materials,such as hardness, tensile strength, seismic resistance, ductility, and corrosion resistance.And the heating processing consists of three stages:
- heat the material slowly;
- The material is maintained at a specific temperature for a specified period of time;
- Cool the material at room temperature.
3.Fihishing Machining
In the precision machining process,the product will be processed strictly according to the dimensions on the drawing within the allowable tolerance range ,and it will become smoother than before.
4.Drilling
According to the design requirements of the product, we will drill holes for the valve seat:Spring hole, threaded hole, grease injection hole and so on,different holes will be made by different drilling tools.
5.Pressure seal ring
We use a dedicated embedding press to embed the valve seat as symmetrically as possible into the valve seat,the valve seat provides initial preload force through its own elasticity.Sealing materials generally include:RPTFE、PEEK、PEFE and so on.
