Eccentric hemispherical valve structure features:
En light eccentric hemispherical valve and flanged valve are the same type of valve, the difference is that its closing part is a sphere, the sphere rotates around the center line of the valve body to achieve a valve that opens and closes. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Two ball valve, three-valve, widely used in recent years is a new type half ball valve eccentric <br> <br> range:
1. Universal valve: reasonable design, compact structure, low flow resistance, good sealing, light and flexible operation, especially suitable for low pressure pipe network of water, sewage, steam, pulp and other media, can be formulated with electric and pneumatic devices, can be realized Automatic operation. (Water, steam, sewage, pulp, mud and other non-corrosive media).
2. Pulverized coal injection: The ideal equipment for controlling the solid transport of dust-laden gas and particulate fluid such as pulverized coal injection. It is widely used in metallurgy, beneficiation, electricity and other production processes for blast furnace pulverized coal injection and pulverizing system. And various piping controls in the dust removal system. It adopts a straight-through structure, the flow channel is unblocked, and there is no clogging. The sealing pair is made of Co-Cr-W alloy. After special heat treatment, the valve is resistant to erosion and abrasion, and the eccentric spherical surface of the valve has automatic compensation performance. By adjusting the bolts on the worm gear, the sealing pair can still achieve the effect of resealing under a certain degree of wear. (dust-laden gas, particulate fluid).
3ã€Specialty for petrochemical industry: For the petrochemical industry, the use of high pressure, high temperature, full of flammable, explosive, general weak acid weak base corrosion-friendly medium, with good sealing, corrosion resistance, open and close light, can automatically remove the valve surface The features such as fouling materials are applicable to the transportation of crude oil, heavy oil and other mediums, petroleum cracking, and food production processes. (oil, natural gas, gas, water, etc.).
4. Blast furnace gas and gas special: The sealing pair adopts Cr—Mn—Si cemented carbide, fire-resistant explosion-proof and anti-static, and the sealing anti-high temperature is 560°C. Its corrosion resistance and anti-biting ability are all more than 6 times that of the stainless steel sealing pair. Suitable for use in gas pipelines, coke oven gas, water gas, liquefied gas, natural gas pipelines and pressurized gate stations.
