Description

Technical Field

[0001] The utility model relates to the field of valve cores, in particular to a valve core. Background Art

[0002] The valve core is a component on the faucet used to control the flow of water. For example, in the Chinese patent CN 201496591U, there is a water outlet, two downwardly protruding water inlet interfaces and two supporting feet at the bottom of the valve core housing. In order to prevent the water valve from leaking out of the water outlet cavity, a rubber ring valve core fixing groove is set on the outer edge of the upper opening of the valve core housing for installing the upper water sealing ring. In addition, there is a pit on the valve cavity interlayer that matches the limiting protrusions at the top of the two supporting feet at the bottom of the valve core housing to achieve positioning with the limiting protrusions on the supporting feet and the pit. However, if the pit is improperly processed and causes a penetration from top to bottom, the water in the water outlet cavity below the upper water sealing ring will leak downward through the pit, causing the faucet to leak.

[0003] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0004] The main purpose of the utility model is to provide a valve core, which solves the problem of water leakage at the connection between the limiting protrusion and the pit mentioned in the background technology.

[0009] Furthermore, the inner ring of the first sealing ring groove and the inner ring of the second sealing ring groove are both provided with a plurality of protrusions.

[0010] Furthermore, the water inlet sealing ring and the boss sealing ring are independently and separately arranged.

[0011] Furthermore, the water inlet sealing ring is connected to the outer wall of the boss sealing ring.

[0012] Furthermore, the water inlet includes a cold water inlet and a hot water inlet; the water inlet sealing ring includes a cold water sealing ring and a hot water sealing ring which are respectively sleeved on the outer circumference of the cold water inlet and the hot water inlet.

[0015] Furthermore, the lateral water outlet is located between the first convex column and the second convex column.

[0016] After adopting the above structure, the valve core of the utility model has at least the following features:

[0017] Beneficial effects:

[0018] 1. By setting a convex column sealing ring on the periphery of the positioning convex column, the pit where the positioning convex column is located is sealed, and the water flow around the valve core will not leak from the pit where the positioning convex column is located. The water inlet sealing ring is set on the periphery of the water inlet, so that the water inlet can also achieve a sealed connection of the waterway by the abutment of the water inlet sealing ring.

[0019] Second, by providing the first sealing ring groove and the second sealing ring groove, it is convenient to fix the water inlet sealing ring and the convex column sealing ring to prevent the sealing ring from shifting. The convex point enables the sealing ring to be clamped in the sealing ring groove to prevent the sealing ring from falling when the valve core is installed.

[0020] 3. The water inlet sealing ring is connected to the outer wall of the boss sealing ring to form an integrated structure, which is convenient for production and assembly. Preferably, the first boss sealing ring is connected to the cold water sealing ring to form an integrated structure, and the second boss sealing ring is connected to the hot water sealing ring to form an integrated structure. The left and right sets of sealing rings have the same structure and can be produced using the same mold, saving production costs.

[0021] 4. The number of the positioning bosses can be one or two. Preferably, the number of the positioning bosses is two to reduce the shaking of the positioning bosses and the pit after the valve core is installed. At this time, the lateral water outlet is set to be located between the first boss and the second boss.

[0022] Compared with the prior art, the utility model blocks the water leakage at the pit where the positioning boss is located by sleeve-arranging a boss sealing ring on the outer periphery of the positioning boss, and even if the pit is opened, it will not affect the normal use of the valve core.
