Description

Technical Field

[0001] The utility model relates to an angle valve, in particular to an angle valve that prevents water hammer. Background Art

[0002] Water hammer is a common phenomenon in pressure pipes. When water hammer occurs, the impact pressure can reach several or even dozens of times the normal water supply pressure, causing severe vibration in the pipes. This can lead to ruptures in water-using equipment and pipes throughout the house, or joints becoming loose and leaking. Existing methods for combating water hammer typically involve installing a water hammer mechanism directly within the water inlet of the valve body. These structures, consisting of a core and spring, are relatively simple and ineffective in preventing water hammer. Utility Model Content

[0029] The elastic buffer 2 and the fixed joint 3 can also be fixed for a second time by welding or chemical connection.

[0030] The fixed joint 3 is threadedly connected to the valve body 1, with a seal provided between the two. Specifically, the seal is a gasket 6.
