Warp Knitting Related Technologies Warp knitting is a type of knitting where the yarns are fed in parallel to the fabric's length. This type of knitting requires specialized equipment and technologies to produce high-quality fabrics. Some of the related technologies used in warp knitting include:
2. Tumbling machine: This machine is used to soften the fabric and improve its texture. The tumbling machine is ideal for producing fabrics that require a soft and smooth feel.
4. Antipilling machine: This machine is used to prevent the fabric from pilling. The antipilling machine is ideal for producing fabrics that require a long lifespan and durability.
5. Mother yarn and mono yarn: These are the two types of yarn used in warp knitting. The mother yarn is used to create the base structure of the fabric, while the mono yarn is used to create the pattern or design on the fabric.

1. Slitting machine: This machine is used to cut the fabric into smaller widths. The slitting machine is essential in producing fabrics with different widths for various applications.
3. Scutching Machine: This machine is used to remove impurities from the fabric. The scutching machine is essential in producing high-quality fabrics that are free from impurities.
In summary, the above technologies are essential in producing high-quality fabrics using warp knitting. They help to improve the texture, durability, and overall quality of the fabric.
Gate valve opening and closing pieces is the gate, the direction of movement of the gate and fluid perpendicular to the gate valve can only be fully open and closed, unsuitable for regulation and throttling. The gate has two sealing surfaces. The two most commonly used wedge gate valves form a wedge on the two sealing faces. The wedge angle varies with the valve parameters, typically 5 °. Wedge gate valve gate can be made as a whole, called the rigid gate; can also be made to produce a small amount of deformation of the gate, to improve its technology to make up for sealing surface angle in the process of deviation, this gate The board is called a flexible gate. Gate valve is closed, the sealing surface can only rely on medium pressure to seal, that is, rely on media pressure to the sealing surface of the gate pressure to the other side of the valve seat to ensure that the sealing surface of the seal, which is self-sealing. Most of the gate valve is forced seal, that is, when the valve is closed, it must rely on external force to force the gate to the valve seat to ensure the sealing surface of the seal. On the role of industry sites play to promote the industry information work of the notice gate valve has the following advantages: 1 fluid resistance, sealing surface erosion by the media and small erosion. 2. Opening and closing more effort. 3 medium flow unrestricted, no spoiler, does not reduce the pressure. 4. Simple shape, short structure length, good manufacturability and wide range of application. Nominal pressure or pressure level: PN1.0-16.0MPa, ANSI CLASS 150-300LB, JIS10-20K Nominal diameter or diameter: DN10 ~ 1000, NPS 1/2 ~ 36 "Connection: flange, butt welding, thread, etc. Applicable temperature: -196 ℃ ~ 700 ℃ Driving mode: manual, bevel gear, pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage Valve body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 ), CF8M (316), CF3M (316L), Ti. Choose different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media. (Valve) moves along the valve seat center line valve.According to the valve disc in this form of movement, valve seat opening changes in proportion with the valve stroke is proportional to the valve stem opening or closing stroke relative to Short and very reliable cut-off, and because valve seat openings vary in direct proportion to valve flap travel, making it ideal for regulating flow rates.Thus, this type of valve is ideally suited for shut-off or adjustment as well as section Flow use. Its selection It is: 1, high temperature, high pressure medium pipe or device should use the cut-off valve, such as thermal power plants, nuclear power plants, petrochemical systems, high-temperature, high pressure pipeline. 2, pipeline convection resistance requirements on the pipeline, Where pressure loss is not considered
