Problems solved by technology
[0002] Conventional valves only have V-shaped combined packing. In the case of frequent switching, they are easy to wear, cause leakage, troublesome replacement and maintenance, short service life, inconvenient production and operation, and bring great trouble to workers.
Conventional valve disc adopts mosaic structure, which is easy to fall off and cause leakage
The valve body and bonnet of conventional welded valves are all welded structures, with many solder joints and welds, which are prone to defects and leakage

Description
technical field [0001] The invention relates to a pipeline fluid control device, in particular to a valve. Background technique [0002] Conventional valves only have V-shaped combined packing. In the case of frequent switching, they are easy to wear, cause leakage, troublesome replacement and maintenance, short service life, inconvenient production and operation, and bring great trouble to workers. Conventional valve disc adopts mosaic structure, which is easy to fall off and cause leakage. The valve body and bonnet of conventional welded valves are all welded structures, with many solder joints and seams, which are prone to defects and leakage. Contents of the invention [0003] The technical problem solved by the present invention is to provide a valve to solve the above-mentioned shortcomings in the background technology. [0004] The technical problem solved by the present invention adopts following technical scheme to realize: [0005] Valves, including dust rings...
