Due to the high pressure of natural gas, the use requirements of forged steel ball valves are high, the structure is relatively complex, and the material requirements are high. Therefore, high-quality forged steel ball valves need to be used to ensure the safe operation of natural gas pipelines. Our company's forged steel ball valves for natural gas have the following characteristics:
1. Unique valve seat sealing structure
The valve seat adopts a front seal design structure, which has two-way sealing and automatic pressure relief functions in the middle cavity. The sealing seat inlaid with sealing material is floating and loaded by spring. When in the closed position, the sealing surface always maintains close contact with the ball, ensuring that the valve can achieve leakage sealing under high and low pressure differences.
2. Automatic pressure relief structure
When the pressure in the middle cavity rises abnormally, the ball valve with a single seal structure has an automatic pressure relief function, while the ball valve with a double seal structure has an additional pressure relief device on the valve body to relieve pressure.
3. Sealed emergency protection function
The valve is designed with an auxiliary seat emergency sealing system. Once the sealing surface is damaged, the corresponding sealant can be injected through the auxiliary sealing system for emergency rescue. If necessary, the valve seat area can also be flushed and lubricated through the auxiliary system.
4. Anti-static device
When the valve is operated, an electrostatic charge is generated and accumulated in the ball rows due to friction between the ball seats. In order to prevent the generation of static sparks, an anti-static device is installed on the valve to discharge the generated static electricity.
5. Fireproof structure
Our company's fixed ball valve seat adopts a unique structure. When a fire occurs and the non-metallic sealing surface material is burned, the metal ring uses the elastic force of the spring to push the valve seat and the ball to seal, thereby preventing the spread of fire and the outflow of the medium.
