Characteristics of electric stainless steel ball valve

Electric stainless steel ball valve is a new type of valve which appeared in the 1950s. In a short period of more than 30 years, it is one of the valve types with rapid development trend in recent ten years. In the pipeline, it is used to disconnect, distribute and change the direction of medium flow. The V-shaped electric stainless steel ball valve also has excellent function of total flow adjustment. The electric stainless steel ball valve can be closed tightly only with the actual operation of turning 90 degrees and small rotating torque. The completely fair inner wall of the oil way plate shows a direct flow passage with little friction resistance for the medium. Electric stainless steel ball valve not only has simple structure and good sealing performance, but also has small volume, light weight, less loss of raw materials, small installation specifications under certain nominal pressure. Moreover, it has small drive torque, simple practical operation, easy to complete quick opening and closing, convenient for actual operation and maintenance, and can be used in general working media such as strong electrolyte, organic solvent, acid and gas It is also suitable for standard extreme media such as CO2, hydrogen peroxide, methane and butadiene. Electric stainless steel ball valve oil way plate can be overall, can also be integral.

Characteristics of electric stainless steel ball valve:

1. Electric stainless steel ball valve has low liquid friction resistance and low fluid density (zero in fact)

2. The electric stainless steel ball valve can open and close the power switch quickly and conveniently.

3. Electric stainless steel ball valve has good sealing performance.

4. Electric stainless steel ball valve has a long service life.

5. The high stability of electric stainless steel ball valve is mainly due to:

① A pair of seal pairs of ball and high-pressure gate valve are not easy to cause common faults such as abrasion and great damage, and are not easy to be stuck in work (when there is no lubricating fluid), so they can be reliably used in corrosive media and low melting point liquid. ；

② The built-in valve seat structure eliminates the potential safety hazard that the valve seat may fly out due to the loosening of the filler cap under the effect of liquid working pressure;

③ The electric stainless steel ball valve with antistatic and fireproof structure is suitable for transportation of crude oil, gas and liquefied gas.

6. The safety passage of valve body is smooth and smooth, which is more suitable for transporting viscous fluid, slurry and solid particles.

7. Because it is not easy to get stuck in work (when there is no lubricating fluid), it can be reliably used in corrosive medium and low melting point liquid.

8. The spherical closing part can be positioned automatically and accurately in the position, and can bear the high pressure difference when closing.

9. In a very large working pressure and temperature range, can complete the complete double seal.

10. When the valve is fully opened and fully closed, the sealing surface of the ball and high-pressure gate valve is protected from the medium, so it is not easy to cause corrosion of the sealing surface according to the medium of the valve at high speed.
