Description

Technical Field

[0001] The utility model relates to a moving porcelain piece and a rotating valve core, which are suitable for angle valves for cold and hot water and quick-opening faucets. Background Art

[0002] For the equipment that switches the fluid on and off, we used a ball valve or valve core structure. Although the ball valve can ensure a large flow rate when the fluid is flowing, it is easily affected by extremely cold weather, resulting in sealing failure, water seepage and leakage, so everyone still tends to use a regulating valve core. The switch valves on the market, especially the rotating valve cores, basically use the valve stem to drive the movable porcelain to rotate, so as to realize the switch or other functions. However, the existing movable porcelain plates are made relatively thick as a whole because they need to be grooved to connect with the valve core operating rod, that is, the basic plate body is thickened again. If it is not thickened, the strength of the plate body will be insufficient. Please refer to the attached figure of the instruction manual for details. This will easily occupy the space of the water outlet cavity of the valve core and affect the water outlet flow of the valve core. Because the movable porcelain plate is made relatively thick as a whole, a groove is opened at both ends above the movable porcelain plate, and there are two plug rods on the operating rod of the valve core. These two rods cooperate with the two grooves to drive the movable porcelain plate to rotate. The plug rod and the groove are on the outer peripheral side of the water outlet cavity. When the plug rod drives the movable porcelain plate to rotate, the outer peripheral wall of the plug rod is tightly matched with the inner peripheral wall of the valve body, so that the plug rod will be affected by the water pressure when it rotates, and the overall cannot offset each other, resulting in the need to overcome the water pressure when rotating the operating rod, which is relatively laborious.
