Electric large-diameter full-bore eccentric semi-ball valve products are divided into six series according to their uses: general valves, pipeline valves, special valves for slurry, special valves for gas, special valves for petrochemical industry, and special valves for pulverized coal injection. There are three types of transmission modes: manual, pneumatic and electric, eight pressure levels (PN0.25~10.0Mpa) and hundreds of specifications (40~1000) of semi-ball valve products. In petroleum, chemical industry, metallurgy, electric power, gas and other industries, it is an updated product of gate valves, globe valves, Y-type valves and ball valves. At present, it has been widely used in pulverized coal injection in the steel industry, slurry, mother liquor and alumina powder transportation in the alumina industry, hydraulic (or dry) ash removal in the power industry, petrochemical industry, gas industry and other occasions.
Scope of application of electric large-diameter full-bore eccentric semi-ball valve
Universal valve: reasonable design, compact structure, small flow resistance, good sealing, light and flexible operation, especially suitable for low-pressure pipe networks of water, sewage, steam, pulp and other media, can be equipped with electric and pneumatic devices, and can realize long-distance automation operate. (Water, steam, sewage, pulp, mud and other non-corrosive media)
Special for pulverized coal injection: Ideal equipment for controlling pulverized coal injection of dust-containing gases and granular fluids and other solid transportation. It is widely used in blast furnace pulverized coal injection, pulverizing systems and dust removal in metallurgy, mineral processing, electric power and other production processes. Various pipeline controls in the system. It adopts a straight-through structure, the flow channel is smooth, and there will be no dust accumulation and blockage. The sealing pair is made of Co-Cr-W alloy. After special heat treatment, the valve is resistant to erosion and wear. At the same time, the eccentric spherical surface of the valve has automatic compensation performance. By adjusting the bolt on the worm gear, the sealing pair can still achieve re-sealing effect even if the sealing pair is worn to a certain extent. (Dust-containing gas, particulate fluid)
Uses of electric large-diameter full-bore eccentric semi-ball valve:
Special for petrochemical industry: For the petrochemical industry, which uses high pressure, high temperature, and is full of flammable, explosive, generally weak acid and weak alkali corrosive media, it has good sealing, corrosion resistance, easy opening and closing, and can automatically remove scaling on the valve surface. It is suitable for the transportation of crude oil, heavy oil and other media as well as petroleum cracking, food production and other processes. (Oil, natural gas, gas, water, etc.)
Special for blast furnace gas and natural gas: the sealing pair is made of Cr-Mn-Si cemented carbide, which is fire-proof, explosion-proof and anti-static. The sealing pair can withstand high temperatures of 560°C. Its corrosion resistance and anti-seizure capabilities are more than 6 times that of stainless steel sealing pairs. It is especially suitable for use in Used for pipeline transportation and pressurized door stations of coal gas, coke oven gas, water gas, liquefied gas, and natural gas. (Blast furnace gas, natural gas, dusty gas, etc.)
Special for slurry mixed fluids: It is the most ideal process valve for transporting two-phase mixed fluid media in processes such as solution slurry and slurry ash that are prone to sedimentation, scaling, and crystallization. It can break through the obstacles of scale formation during closing and achieve smooth closing. It has a novel structure and unique design, and has the advantages of high efficiency, energy saving, good wear resistance, reliable sealing, light operation, rapid opening and closing, and long service life. (Transportation of particulate matter such as process slurry, slurry ash and slag)
Special for pipelines: It is a straight-through semi-ball valve with no diameter reduction. The valve body channel is connected to the pipe connected to the pipeline as a straight pipe. The cross-sectional area is equal and the resistance is less than the diameter reduction. Full opening and full closing can be achieved by turning 90 degrees, which is convenient for long valves. Distance pipeline transportation control. (Pulverized coal injection and gas transportation)
Electric full-bore eccentric semi-ball valve has the following advantages:
1. The side-mounted type has a compact structure and light valve weight, and is suitable for occasions where the valve installation space is required.
2. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.
3. It has simple structure, small size and light weight.
4. It has a cutting function and can cut off debris (branches, textile bags, etc.) in the medium when closed.
5. Tight and reliable, the sealing surface material of the ball valve is widely made of plastic, which has good sealing performance and has also been widely used in vacuum systems.
6. It is easy to operate and opens and closes quickly. It only needs to be rotated 90° from fully open to fully closed, which is convenient for long-distance control.
7. It is easy to maintain. The ball valve has a simple structure and the sealing ring is generally movable, making it easy to disassemble and replace.
8. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface.
9. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should all present a spherical surface at the inlet and outlet, thus cutting off the flow.
