二、進口彈簧微啟式安全閥結構優點：

1.排量較小，節約能源；

2.整定壓力偏差小，可達±3%；

3.啟閉壓差≤15%；

4.選用優質的彈簧鋼，保證彈簧的壽命和穩定性；

5.平面結構的閥瓣和閥座易于維修和重新加工；

6.整定壓力范圍大:0.1～42.0MPa

二、 Advantages of imported spring micro open safety valve structure:
1. Small displacement, energy saving;
2. The setting pressure deviation is small, up to ± 3%;
3. Opening and closing pressure difference ≤ 15%;
4. Select high quality spring steel to ensure the service life and stability of the spring;
5. The disc and seat with plane structure are easy to repair and reprocess;
6. Wide range of setting pressure: 0.1 ~ 42.0mpa

三、進口彈簧微啟式安全閥描述：

德國《DE LOCKE》洛克進口彈簧微啟式安全閥適用于工作溫度≤350℃的蒸汽、水等介質的設備和管路上。作為超壓保護裝置。是一種安全保護用閥，它的啟閉件受外力作用下處于常閉狀態，當設備或管道內的介質壓力升高，超過規定值時自動開啟，通過向系統外排放介質來防止管道或設備內介質壓力超過規定數值。

三、 Description of inlet spring micro open safety valve:
German "de lock" imported spring micro open safety valve is suitable for steam, water and other media equipment and pipelines with working temperature ≤ 350 ℃. As overpressure protection device. It is a kind of valve for safety protection. Its opening and closing parts are normally closed under the action of external force. When the medium pressure in the equipment or pipeline rises and exceeds the specified value, it will automatically open. By discharging medium to the outside of the system, it can prevent the medium pressure in the pipeline or equipment from exceeding the specified value.
