Description

Technical Field

[0001] The utility model relates to the field of PPR pipe connectors, in particular to a PPR cold and hot water pipe connector. Background Art

[0002] As an indispensable and key part of the PPR piping system, PPR hot and cold water pipe connectors are crucial to the safety and reliability of the entire piping system. Therefore, when purchasing and using, regular brands and manufacturers should be preferred, and construction and installation specifications should be followed to ensure the smooth operation of the piping system and extend its service life. PPR hot and cold water pipe connectors are popular in modern home and construction fields, and their excellent durability, simple installation and economic benefits have won the favor of users. However, in practical applications, the control valve, as an important part of the connector, causes wear of the internal adapter due to frequent rotation when adjusting the water flow. Long-term friction and rotation will gradually wear out internal parts such as seals and bearings, which not only affects the normal operation of the control valve, but may also cause water leakage and even more serious safety problems. Once the internal adapter is severely worn and needs to be replaced, due to the structural characteristics of the PPR connector, it is often necessary to disassemble the entire connector, which not only increases the difficulty of maintenance, but also may cause damage to other parts. Therefore, many users have to choose to replace the entire connector, which undoubtedly increases the maintenance cost and may affect the user experience. Utility Model Content
