Supply SQ647FM Coal Injection Ball Valve carbon steel flange hard seal pneumatic ash discharge fixed ball valve

Ball valves are commonly used in oil, natural gas, coal and ore mining, refining and processing and pipeline transportation system to cut off or connect the medium. Coal injection ball valves are suitable for blast furnace pulverized coal blowing and pulverizing system, dusty solid powder pipeline system, air pipeline and lance pipeline in ironmaking plant, etc. Coal injection system of blast furnace pulverized coal blowing valve, coal delivery valve, safety valve, nitrogen charging valve, charging valve, make-up valve, fluidizing valve, equalizing valve, etc. Applicable temperature:-28°C~300°C.

1. The valve seat of the ball valve for coal injection is equipped with an automatic compensation device for wear, which ensures the sealing performance of the ball valve more reliably.

2. The sealing ring of the ball valve for coal injection is made of carbon fiber material, which has the characteristics of temperature resistance, abrasion resistance and long service life.

3. The valve stem can be made of A182F (1Cr13) integral forging and modulation treatment, the hardness reaches HB220-250, the valve stem adopts the design of anti-blowout structure, and the valve stem can be lengthened according to the need for buried places. 4. According to the customer's need, the coal injection ball valves can be designed into an anti-static structure, and conductive springs can be set up between the sphere and the valve stem and the valve stem and the valve body, to avoid static ignition ignition of inflammable substances, and ensure the safety of the system. System safety.

5. Various sealing vice forms can be selected according to different working conditions, such as soft sealing structure, hard sealing structure, fireproof valve seat structure and other structural designs.

6. According to the needs of the auxiliary sealing structure can be set up to inject grease, in the valve seat and valve stem parts of the installation of grease injection valve can be temporarily sealed in emergencies.

7. Coal injection ball valve also has a compact valve structure, opening and closing flexible, easy to install and maintain and so on. 8. Manual part can be used to press the steel handle or stainless steel casting of the handle. The handle is equipped with a limit structure, in the valve open, closed position set limit, when the valve is used in the key device, the limit block is equipped with a lock hole can lock the switch position to avoid misoperation. The handle is clearly marked open and closed.
