Gate Valve Repair

Gate valve repair technologies will have a direct relevance to the maintenance of basic knowledge of valve gate, Jiangyin City, Oulei Si gate valve repair in the accumulation of knowledge is very seriously! Maintenance valve gate valve gate to make it clear how the maintenance of the gate valve repair must have a basic understanding of: gate valve can be fully open and fully closed, is not suitable for regulation and cut costs, but the gate valve is the gate open and close cases board, ram direction of motion perpendicular to the direction of the fluid. Gate valve gate has two sealing surface, which is indispensable to the maintenance gate valve repair content. The most commonly used wedge gate valve sealing surface to form two wedge-shaped, wedge-shaped angle with the valve parameters vary, typically 5 degrees, which is Jiangyin Oulei Si gate valve repair the results of the most frequently encountered form. Wedge gate valve wedge gate valve repair according to the different institutions and not a wedge-type gate valve gate can be made into a whole, called the rigid damper; also be made to produce small quantities of deformation gate in order to improve nature of their craft to make up for the sealing surface angle generated in the process in the processing error, this gate is called the flexible gate, Jiangyin City, Ou Leisi call this as: flexible gate valve repair. Self-sealing Gate Valve Repair Structure: gate valve closed, the sealing surface can only rely on media pressure to seal, that is, to rely on media pressure to ram pressure to the other side of the sealing surface of the valve seat to ensure the sealing surface of the seal. Most of mandatory sealed valve is used, namely, the valve is closed, we must rely on outside pressure to force the gate to the seat in order to ensure the sealing surface of the seal. In the gate valve repair, it can be very clearly valve has the following advantages: 1. Fluid resistance is small, the sealing surface by the media, a small scouring and erosion. 2. Open and close more effort. 3. Medium flows unrestricted, non-spoiler, without reducing pressure. 4. A simple shape, structure, length short, good manufacturing processes applicable to a wide range. Jiangyin Oulei Si maintenance of the valve gate range: nominal pressure or stress level: PN1.0-100MPa, ANSI CLASS 150-300LB, JIS10-20K Nominal diameter or caliber: DN10 ~ 1800mm, NPS 1 / 2 ~ 36 " Gate valve maintenance program in the selection of a different material, may be separately applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. valve gate valve repair materials: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. valve gate repair connections: flange, butt welding, thread and other valve repair for temperature: -196 ℃ ~ 700 ℃ Gate valve repair, drive mode: Manual, bevel gear, pneumatic, electric, hydraulic, Pneumatic, electro-hydraulic valve linkage, and so the door repair.
