Uses/application of manual butterfly valve:
Used in the gas pipeline in the sulfuric acid industry: the inlet and outlet of the blower in front of the furnace, the inlet and outlet of the relay fan, the electric demisting series and the connecting valve, the inlet and outlet of the S02 main blower, the adjustment of the converter, the inlet and outlet of the preheater, etc. and
the use of cut-off gas.
It is used in the sulfur burning, conversion and dry absorption sections of the sulfur-burning sulphuric acid plant. It is the preferred brand of valves for the sulphur-burning sulphuric acid plant. It is regarded by the majority of users as: good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient operation, The flexible, safe and reliable butterfly valve has been widely used.
It is also widely used in: SO2, steam, air, gas, ammonia, CO2, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid in the chemical, petrochemical, smelting, pharmaceutical, food and other industries It is used as a regulating and intercepting device on the pipeline of other medium.
Structural features of manual butterfly valve:
- The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve.
- Elastic seal is produced by torque.
- The clever wedge-shaped design enables the valve to have an automatic sealing function that is tighter and tighter, and the sealing surfaces are compensated and leak-free.
- Small size, light weight, light operation and easy installation.
- Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
- The material of replacement parts can be applied to various media, and can be lining anti-corrosion (lining F46, GXPP, PO, etc.).
- Diversified continuous structure: wafer, flange, butt welding.
