TECHNICAL FIELD

[0001] The utility model relates to a testing fixture for faucet valve core seat. BACKGROUND

[0002] The valve core is a basic function valve part for realizing flow control of the faucet. When the handle of the faucet is rotated, the position of the valve core relative to the valve core seat changes, thereby controlling the size and flow direction of the water flow. The structure of the valve core seat is shown in Figures 9-11 In order to enable the valve core seat to cooperate with the valve core to accurately control the water flow, it is crucial to ensure that the machining precision of the valve core seat, especially the precision of the multiple machining positions of the side surface and the top of the valve core seat, is within the required range. Therefore, after the valve core seat is machined, the multiple machining positions of the valve core seat need to be detected.
