Selection of various types of needle valve principle

1, low temperature medium piping systems and devices, should use the valve cover with a low temperature needle valve. 2, oil refining unit of the catalytic cracking unit piping system, optional lifting rod needle valve. 3, acid and alkali chemical systems and other corrosive media and piping systems, should be made of austenitic stainless steel, PTFE valve seat ring all-stainless steel needle valve. 4, Metallurgical systems, power systems, petrochemical plants, urban heating systems in high temperature medium piping systems or devices, the choice of metal to metal seal needle valve. 5, the need for flow control, the choice of worm-driven, pneumatic or electric with V-shaped opening of the needle valve. 6, oil, natural gas pipeline delivery, need to clean the pipeline, but also need to be buried in the ground, the choice of full diameter, all-welded needle valve structure; buried in the ground, the choice of full-diameter welding connection or flange connection Ball valve 7, refined oil pipeline and storage equipment, the choice of flanged needle valve. 8, city gas and natural gas pipeline, the choice of flange connection and internal thread connection needle valve. 9, oxygen pipeline system in the metallurgical system, should be adopted after strictly degreasing, flanged needle valve.

Warp Knitting Machine Spare Parts

Warp knitting machines are used for the production of high-quality fabrics with intricate designs. These machines require various spare parts to ensure smooth and efficient operation. Here are some of the most common Warp Knitting Machine spare parts and their applications:

1. Needles: Needles are one of the most critical spare parts of a warp knitting machine. They are used to form the loops that create the fabric. Needles come in different sizes and shapes, depending on the type of fabric being produced, e.g., compound needle, slider needle, guide needle, threading comb and so on.

2. Sinkers: Sinkers are used to hold the fabric down as the needles form the loops. They come in different shapes and sizes and are made of various materials, including steel and plastic.

3. Guide bars: Guide bars are used to control the movement of the yarn as it is fed into the machine. They are available in different configurations, depending on the desired fabric design.

4. Electronic components: Modern warp knitting machines often require electronic components such as sensors, controllers, motors and EBC/EL device. These parts help to automate the machine and improve its efficiency.

5. Others like Piezo Jacquard, Warp Knitting Bellow, KFD tension device are also important to the machines.

In conclusion, warp knitting machine spare parts are essential for the smooth operation of these machines. They come in various shapes, sizes, and materials, and their selection depends on the type of fabric being produced and the machine's design.
