Forged steel ball valve is mainly used in oil, gas of long distance pipeline transfer and city gas pipeline system. Because of long distance pipeline with the specific characteristics, so the valve in the design has fully considered the bear pipe stress ability, as well as safety, weathering resistance, long-term use of reliability, etc; Sealing structure design of stunt company. Operation mode has unique worm worm gear drive, manual – pneumatically, electrically, gas, electricity liquid linkage liquid linkage, as well as all kinds of special control form.
Forged steel ball valves feature
1. Double truncated and emission (2) security decompression 3. Reliable seal 4. Fireproofing design 5. Clean pipe 6. Emergency seal 7. Special valves 8.influencing bonnet combined sealing 9. Blowdown 10. After long stem 11. Antistatic design 12. Bear pipe stress safety
Some forging steel ball valve body says on the arrow, if not accompanied by an English FIOW handwriting, is direction, not seal seat as the flow direction of medium reference, the valve from discharge in opposite directions. Normally, two-seater sealing ball valves with two-way flow.
The design of the main characteristics are: full size/shrink diameter, 90 degrees positioning and locking structure, Special form of “Y” head hilt, Fire prevention and antistatic design; A pair of wing spring; cheung Blow-out proof stem, Stem central double seal structure, Bolts, threaded gasket seal bonnet.
Valve installation:
Valve installations and other mechanical equipment installation as, there is an attitude problem, install valve is installed correctly attitude should be internal structure types accord with medium flow, install valve posture accord with structural type of specific requirements and operational requirements. In addition, correct posture contains neat and tidy, beautiful and easy feeling, it is modern art modelling, the technical and artistic both organic union.
Applicable scope
Forged steel fixed ball valve is mainly used in chemical industry, metallurgy, petroleum, pharmaceutical sectors of high-pressure medium pipeline, applicable temperature: – 196 ~ 450 ℃; Drive mode: manual, pneumatic, electric, hydraulic, turbine move etc; Nominal size: 1/2 “~ 12″, Nominal pressure: 150LB ~ 1500LB; Applicable medium: water, gas, oil, gas and alkali corrosion medium.
