What Are The Structural Advantages Of Hard Forged Steel Ball Valves?

Two-way isolation and discharge function, fire-fighting knowledge construction, emergency grease injection, emergency rescue, reliable valve stem seal.

1. Two-way barrier and charge and discharge function

Hard forged steel ball valve adopts a torsion spring torque fluctuation valve seat. Regardless of whether the valve is open or closed, the upstream and downstream valve seats block the liquid, and the retentate in the valve kidney tube is discharged through the discharge valve.

2. Fully automatic pressure relief function

When the working pressure rises abnormally due to the rise of the temperature of the substance remaining in the kidney tube of the hard forged steel ball valve, only the function of the valve seat can be used to automatically relieve the pressure without passing through the valve, which is very important for ensuring the stability of the valve when transporting liquid substances. important.

3. Structure of fire protection knowledge

The hard-forged steel ball valve has the function of fire protection knowledge, and its design and manufacture conform to API607 and API6FA.

4. Sealing emergency grease injection emergency rescue

Hard forged steel ball valves accidentally seal the seat due to dirt in the material or fire. The grease injection valve brings the interconnection with the grease injection gun, which can save time and labor to introduce the sealing grease into the sealing position of the valve seat and reduce leakage.

5. Adjective (abbreviation of the verb) Reliable valve stem seal and high operating torque

The addition of graphite packing and the introduction of sealing vegetable grease will reduce the leakage of the valve stem after a fire to a lower level. The rolling bearing and thrust ball bearing of the valve stem to make the valve easy to operate.

6. Linking verbs full aperture or reduced aperture

Hard forged steel ball valves can be selected according to the application of full diameter or reduced diameter structure. The product circulation diameter of the full-bore valve is consistent with the inner diameter of the pipeline, which is conducive to the dredging of the pipeline.

Seven, the valve stem can be extended.

Hard-forged steel ball valves can also extend the valve stem according to the needs of assembly or operation. The extension stem gate valve is especially suitable for places where pipelines need to be laid, such as town gas. The size of the extended valve stem is determined according to customer requirements.

Eight, flexible operation

The hard-forged steel ball valve uses rolling bearings on the seat and stem, which have low frictional resistance and good self-lubricating properties, which can reduce the operating torque of the valve. Therefore, even if no sealing grease is provided, the valve can operate flexibly for a long time.

Nine, there are many kinds of driving forms, which are convenient for completing the automatic control system.

Hard-forged steel ball valves have flexible drive forms, and the operation methods can be manual, pneumatic, electric, gas-liquid linkage, hydraulic press, etc. According to demand.
