1. Double blocking and discharging function: The fixed ball valve adopts a spring preloading floating valve seat. When the valve is in the fully open or fully closed state, the valve seat on the upstream and downstream sides blocks the fluid, and the retentate in the valve body is discharged through the discharge valve. .
2. Automatic pressure relief function: When the valve body cavity stays in the medium temperature and causes abnormal pressure rise, it does not need to pass the safety valve, but the valve seat function can automatically release pressure, which ensures the safety of the valve when conveying liquid medium. Sex is very important.
3, fire safety structure: the valve has fire safety function, its design, manufacture are in accordance with API 607 ​​and API 6FA specifications. Fixed ball valve picture fixed ball valve structure diagram fixed ball valve picture
1. Sealed emergency grease injection: Due to the accidental failure of the valve seat seal due to foreign matter or fire in the medium, the grease injection valve provides a quick connection with the grease gun, which can quickly and easily inject the sealing grease into the seat sealing portion to relieve leakage. .
2. Reliable stem seal and low operating torque: In addition to the standard sealing ring, the “O†seal is also installed on the packing gland. The double seal ensures the reliability of the stem seal; the added graphite packing and Sealant injection minimizes valve stem leakage after a fire. The stem sliding bearing and the thrust bearing make the valve easy to operate.
3, full diameter or reduced diameter: can be selected according to the need for full diameter or reduced diameter structure. The full-bore valve flow orifice diameter is consistent with the inner diameter of the pipeline to facilitate pipeline cleaning.
4, the valve stem can be lengthened: according to the needs of installation or operation, the valve stem can be lengthened. The extended rod ball valve is especially suitable for occasions where underground gas pipelines need to be buried. The length of the stem is determined according to customer needs.
5, flexible operation: the use of a small friction coefficient and good self-lubricating valve seat and stem bearings, greatly reducing the operating torque of the valve. Therefore, the valve can be operated flexibly and freely for a long period of time even without providing sealing grease.
2. In the usual form and method of ingestion.
3. Marked with a label biological adjustment functions.
