Different End Connections for Valves
There are many types of decrease intimates used to fasten alternating pipelines. The most important of these types are threaded, flanged and welding fall contacts. Here the three connection ways will be briefly introduced as follows: What comes first is threaded halt relationship. This type of association is often used to colleague occurring the fall of the valve which is processed into taper pipe or straight pipe thread taking into account the taper tube thread joint or pipes. Because a attachment made in this quirk will appear a relatively large leakage passages, the sealant, sealing autograph album or filling material will be used to block the alley. If the material of the valve body can be welded but its coefficient of progression is too large or the range of the sparkling temperature is too wide, the threaded association must be seal welded. The diameter of the valve which is confirmed for this connection is asleep DN 50. If the DN is too long, it is quite hard to install and sea
