Electric ceramic ball valve

First, an overview of electric ceramic ball valve

Electric ceramic ball valve has superior corrosion resistance, high temperature resistance, wear resistance and erosion and other notable features. Widely used in petrochemical, metallurgy, papermaking, power plants, oil refining and other industries of all kinds of acid-base gas, liquid, high temperature steam and slurry delivery system. Is a strong corrosion of titanium valves, Monel valves ideal alternative. Zirconia ceramic ball valve with low cost, high operating economy and long life (titanium valve is 2 to 4 times) advantages. The driving methods are manual, pneumatic, pneumatic spring reset, electric and so on. And according to the requirements of users design all kinds of special ceramic valves. Applicable to all kinds of acid, alkali, salt liquid, gas medium environment, hard sealing valve is especially suitable for with granular, fibrous media environment.
 

Second, the performance of electric ceramic ball valve introduced

1, the ceramic ball valve spool with high performance structural ceramics, its excellent chemical stability and high hardness (≥ HRA88 above, second only to diamond) to ensure that the valve ball and valve seat sealing surface will not be medium corrosion and wear, In order to ensure good sealing performance of the valve.

2, ceramic seal valve with 99.5% alumina ceramic structure, sintering temperature of 1700 ℃. Therefore, ceramic valve is the best choice for high temperature valve conditions

3, The spherical sealing structure between the ceramic valve ball and the valve seat is made of the ceramic processing technology imported from Taiwan. The sealing performance is higher than other hard-sealing ball valves, achieving zero leakage (leakage level VI).

4, the structural ceramic thermal expansion coefficient is small, deformation in the high temperature conditions is minimal, there will be no change due to temperature sealing surface failure problems.

5, the ceramic sealing surface after precision grinding, the surface roughness is less than Ra0.2, the ball roundness error of less than 0.005, combined with the ceramic high hardness and self-lubricating properties, the sealing surface of the seal pressure is far less than ordinary soft-sealed ball valve , About ordinary hard seal ball valve 1/5 or even lower, so the valve opening and closing torque is small, the switch is smooth, adjust the valve when used as a high sensitivity.

6, the body shell using three-stage structure, the use of A105N / SS304 forgings, reasonable structural design effectively protect the internal ceramic spool.
 

Third, the characteristics of electric ceramic ball valve

Ceramic ball valve body for the three-stage structure, the use of carbon steel or stainless steel forgings, solid body, beautiful appearance. Valve internal media through the part of the ball, seat, take over the structure of ceramic materials. Structural ceramic chemical stability, high hardness (up to HRA88), resistant to most acid 堿 medium corrosion, and has excellent wear resistance, to solve the common metal and plastic valves can not wear and corrosion resistance can not The issue of employment. Valve ceramic inner parts by a ball, two seat, two take over a total of six rational composition, the overall structure is simple, smooth flow, medium flow resistance. Ball and valve seat sealing surface is hard-sealed spherical, using imported advanced spherical processing technology from Taiwan, the surface characteristics of a good, the ball is high, due to structural ceramics with self-cleaning and self-lubricating, so that the entire valve seal Excellent performance, zero leakage, and tight sealing without significant pressure, reducing stem torque and smooth switching.
 

Fourth, the application of electric ceramic ball valve conditions

Power plant desulfurization and denitrification, lime slurry, petrochemical pipelines, paper and printing wastewater treatment, sulfuric acid industry, chlorine and other industrial corrosive medium and contain solid particles, fibers and other harsh conditions.
