On the classification and characteristics of VCR joints, we have sorted out a few simple content, a simple understanding of the product characteristics of VCR joints, to help us better use VCR joints. Next, on the classification and characteristics of the VCR connector, jiangmen iresearch precision machinery for you to do the following.
VCR connector has the characteristics of strong connection, high pressure resistance, good tightness and repeatability, easy installation and maintenance, safe and reliable work, etc. It is widely used in semiconductor manufacturing, tft-lcd, solar energy, nuclear energy, LED, petrochemical, biomedical manufacturing, food, standard testing, laboratory and other fields. The classification and characteristics of VCR connector are briefly described. The characteristics of VCR connector are as follows:
1. The VCR connector has a high cleanliness, and the components are treated by electropolishing, cleaning and other processes with good tightness, which is especially suitable for the ultra-high purity system, ultra-high vacuum system and high-pressure system requiring no leakage. Because the metal sealing element, VCR joint rated working temperature range is wide, adopting SUS316L gasket VCR joint, temperature rating up to 537 ℃. The VCR connector is easy to install and has minimum disassembly clearance. It can be disassembled and assembled repeatedly. New gaskets need to be replaced after disassembly and reinstallation.
2. Welding is required between the Gland and TUBE of the VCR joint. In general, VCR joints should be used together with automatic welding joints. Automatic welding joints should be used in places that do not need to be removed, and VCR joints should be used in places that need to be removed, such as the joints of valves and equipment. Therefore, many manufacturers put the VCR joint and automatic welding joint together on the samples, and some manufacturers also call these two kinds of joint as clean pipe fitting.
VCR joints can be classified into long type and short type. According to the welding form can be divided into butt welding, shoulder welding, socket welding ; According to the matching nut can be divided into male and female.
