Additive butterfly valve
The pneumatic additive butterfly valve of the CPD mixing plant is mainly used for the open action of corrosive additives and liquid scales, hoppers, etc. It adopts gear and rack transmission, with high torque, standardized configuration of dedicated cylinders, and switch signal output. The sealing rubber ring is made of wear-resistant rubber, which is corrosion-resistant and has good sealing performance. The pneumatic additive butterfly valve of CPD6 mixing plant has the characteristics of anti leakage, corrosion resistance, fast installation, and stable quality. It is widely used in powder and liquid industries such as building materials, chemical industry, and cement plants. There are two types of device forms: clamp type and flange type; The main material can be selected from various specifications such as cast aluminum and iron.
1. Structural and functional characteristics
Rotating jet design: By using a rotating tube and blade structure to maintain the movement of the additive, sedimentation is prevented and homogeneity is ensured.
Pneumatic control: using pneumatic butterfly valves (such as CPD series) to achieve rapid opening and closing, suitable for the precise feeding requirements of automated mixing plants.
Sealing forms: There are two common types of seals: soft seals (such as rubber or PTFE valve seats) and hard seals (metal valve seats). The former is suitable for room temperature media, while the latter is resistant to high temperature and high pressure.
2. Typical product models
CPD series: such as CPD6-40WF, CPD6-65WF, etc., with a nominal pressure of 1.0-1.6MPa, suitable for water, gas, and oil media.
GTD6-65WF: Pneumatic drive, clamp type installation, commonly used in mixing plant additive pipelines.
3. Selection and maintenance suggestions
Material selection: Fluorine lined butterfly valves (such as PTFE material) can be selected for corrosive environments, and nylon coatings or metal hard seals can be selected for conventional working conditions.
Maintenance points: Regularly check the wear of the sealing surface, and clean the air supply pipeline of the pneumatic valve to prevent impurities from sticking.
4. Application scenarios
The intelligent temperature control system of the nuclear power concrete mixing plant, combined with the admixture pump, achieves closed-loop control.
Transportation of slurry or corrosive media in municipal engineering and chemical fields.
