The sealing oil vacuum tank float valve PYF-100 is a mechanical float level controller. It automatically controls the oil replenishment of the oil tank or other containers to keep the oil tank within the specified liquid level range. It is mainly used for the liquid level control of the vacuum oil tank of the single-flow ring oil seal control system of the hydrogen-cooled steam turbine generator. It can also be used for the medium replenishment of other similar oil tanks or water tanks. The sealing oil vacuum tank float valve is mainly composed of a valve body, a piston, a needle plug, a transmission mechanism, and a ball valve. When the oil level in the oil tank drops, the buoyancy of the float decreases, and the force of the needle plug to the right is greater than the force of the buoyancy of the float to the left, the needle plug moves to the right, opens the center hole of the piston, and the pressure oil in the upper chamber of the piston is discharged to the vacuum oil tank. The pressure oil in the middle chamber of the piston pushes the piston to the right, and the valve opens to replenish oil to the tank. |
Technical Specification "Type: Float valve Material: Stainless steel Size range: DN40~DN80 Nominal pressure: 0.5~1.6MPa Work itinerary: 10mm Applicable temperature: -196~425ºC Applicable medium: Various fluid media such as water, steam, oil, gas, acid, alkali, etc Sealing type: Metal sealing Structural style: L-shaped Executive standards: Complies with international standards Accessaries: Floating ball, handle, etc Function: Check, adjust, etc" |
Product Features: 1. Automatic control and adjustment: By automatically opening and closing the float valve, precise control and adjustment of the flow and liquid level of lubricating oil can be achieved. 2. Hydraulic amplification principle: By using hydraulic amplification to adjust the piston, it can achieve large displacement and force output under small force, improving the sensitivity and response speed of the valve. 3. Simple and reliable structure: The structure of the floating ball valve is relatively simple, consisting of a few key components, which improves its reliability and maintainability. |
Applications of Float Valve: 1. Liquid level control of the sealing oil tank of the steam turbine generator. 2. Liquid level control of petrochemical oil tanks, storage tanks, and separators. 3. Liquid level control of metallurgical industry equipment. 4. Liquid level control of water tanks in the pulp and paper industry. 5. Level control and flow regulation of process engineering and automation systems. |
