一、 Using:
The didlink check valve is installed in the pipeline system, and its main function is to prevent the medium from flowing back. The check valve is an automatic valve that depends on the pressure of the medium to open and close. Wafer check valve is suitable for various pipelines with nominal pressure PN1.0MPa~42.0MPa,Class150~25000,nominal diameter DN15~1200mm,NPS1/2~48, working temperature -196~540℃, to prevent The medium flows back. By selecting different materials, it can be applied to a variety of media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and uric acid.
二、Structural features:
1. The structure length is short, and its structure length is only 1/4~1/8 of the traditional flange check valve;
2. Small size and light weight, its weight is only 1/4~1/20 of the traditional flange check valve;
3. The valve flap closes quickly and the water hammer pressure is small;
4. Both horizontal pipes and vertical pipes can be used, and the installation is convenient;
5. The flow channel is unobstructed and the fluid resistance is small;
6. Sensitive action and good sealing performance;
7. The valve disc has short stroke and small closing impact;
8. The overall structure is simple and compact, and the appearance is beautiful.
9. Long service life and reliable performance.
