Lined fluorine valves are a type of valve. The opening and closing component of a lined fluorine valve is a gate plate, and the movement direction of the gate plate is perpendicular to the fluid flow direction. Lined fluorine gate valves can only be fully opened or closed, but cannot be adjusted or throttled. The gate has two sealing surfaces; the two sealing surfaces of common gate valves are wedge-shaped. The wedge angle varies with valve parameters and is 25°2' when the medium temperature is not high. The wedge-shaped gate plate of the gate valve can be made as a whole, called a rigid gate; to improve manufacturability, it can also be made with a slightly deformable gate to compensate for deviations in the sealing surface angle during processing. This type of gate is called an elastic gate.
Fluorine-lined valves are a type of valve. Fluorine-lined valves The opening and closing component is a gate plate, and the movement direction of the gate plate is perpendicular to the fluid direction. Fluorine-lined valves can only be fully opened or closed, but cannot regulate or throttle. The gate has two sealing surfaces; common gate valves have two wedge-shaped sealing surfaces. The wedge angle varies with valve parameters, and is 25° when the medium temperature is not high. The wedge-shaped gate plate of the gate valve can be made as a whole, called a rigid gate plate; to improve manufacturability, it can also be made with a slight deformation at the gate to compensate for angle deviations in the sealing surface during processing. This type of gate is called an elastic gate plate. Next, we will introduce some knowledge about Fluorine-lined valves it. Summarizing experience.
With the rapid economic development of modern Chinese industrial enterprises, fluorine-lined gate valves and various pipeline accessories can be rapidly applied in fields such as petroleum, dyeing, and chemical industries, showing strong vitality. As a priority project in construction engineering, it has attracted great attention and favor from engineering design and construction management units, and is a product with potential demand in the international market.
1. Low fluid resistance, and the sealing surface is less eroded and scoured by the medium.
2. Easier to open and close.
3. The direction of the medium flow is not restricted, causing no turbulence or pressure drop.
4. Simple shape, short structural length, good manufacturability, and wide applicability.
Flush valves, also known as fluoroplastic-lined corrosion valves, use polytetrafluoroethylene resin (or profile processing) or embedding methods to form steel or iron valve compression parts (the same method applies to various pressure vessels and pipeline accessory linings).
In pipeline valves, lining technology is used in places within the valve body where the medium can reach. The lining material is usually fluoroplastic, such as FEP (F46) or PCTFE (F3), suitable for sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, or various organic acids, strong acids, and strong oxidizers.
Fluorine valves are divided into the following categories:
Fluorine gate valves
Fluorine-lined butterfly valves
Fluorine-lined check valves, fluorine-lined globe valves, fluorine-lined plug valves, fluorine-lined diaphragm valves, fluorine-lined filters, fluorine-lined relief valves, fluorine-lined control valves, fluorine-lined pipes, and fluorine-lined sight glasses. The adhesive of this invention can give the lining rubber a strong affinity with the pipe wall, good corrosion resistance, anti-fouling performance, and long service life. In addition, the valve can be made with characteristics of metal strength and corrosion resistance.
All products are designed and manufactured according to chemical enterprise standard systems and can be adapted to various development situations and uses. Additionally, various fluorine-lined products are customized based on customer service needs.
