Metal elastic sealing butterfly valveUse and structural characteristics
Metal elastic sealing butterfly valveuse:
The eccentric butterfly plate is installed on the valve stem, and the edge of the metal elastic sealing butterfly valve is conical and spherical, and is matched with the elastic sealing ring.
It is used for gas pipelines 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 series and connection valves of the electric demister, 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 incineration, conversion and dry suction sections of the sulfuric acid system. It is the preferred brand of valves for sulfuric acid plants. It is considered by the majority of users as: good sealing performance, light operation, secondary corrosion, high temperature resistance, and easy operation. , flexible, safe and reliable butterfly valve, has been widely used.
It is also widely used in: SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid in chemical, petrochemical, smelting, pharmaceutical, food and other industries It is used as a regulating and shut-off device on pipelines such as medium.
Metal elastic sealing butterfly valveStructural features:
1. An elastic seal is produced by torque.
2. Diversification of continuous structure: wafer, flange, butt welding.
Three, small size, light weight, light operation, easy to install.
4. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
5. The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve.
6. The material of replacement parts can be applied to various media, and can be lined with anti-corrosion (lining with F46, GXPP, PO, etc.).
7. The ingenious wedge-shaped design enables the valve to have an automatic sealing function of tighter and tighter closure, with compensatory and zero leakage between the sealing surfaces.
The above has shared the use and structural characteristics of the metal elastic sealing butterfly valve.clearly for everyoneThe characteristics of the seven-point metal elastic sealing butterfly valve are expounded.
