Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of faucets, and in particular relates to a faucet valve core. Background Art
[0002] The valve core is the device that controls the opening and closing of a faucet and regulates the flow rate and temperature of the water outlet. It is the heart of the faucet. In existing rotary valve cores, a rotating rod is inserted into the valve core body, with several sealing rings installed at the connection between the rotating rod and the valve core body. Typically, the valve core body is made entirely of cast iron or steel. The sealing rings can easily fail due to prolonged friction between the sealing ring and the inner wall of the valve core body, resulting in poor sealing performance. Therefore, a faucet valve core with wear resistance and good sealing performance is needed. Utility Model Content

[0004] An embodiment of the present utility model is implemented as follows: a faucet valve core, the faucet valve core includes a rotating rod, an outer valve core body, an inner valve core body, a movable valve plate and a fixed valve plate; the inner valve core body is inserted into the outer valve core body, the rotating rod is inserted into the inner valve core body, and a sealing ring is provided between the inner valve core body and the rotating rod; the movable valve plate and the fixed valve plate are arranged in sequence inside the inner valve core body; the rotating rod drives the movable valve plate to rotate; the inner valve core body is made of plastic.
[0005] Furthermore, the faucet valve core also includes a water sealing sleeve, which is arranged at the bottom of the inner valve core body to support the fixed valve plate.
[0006] Furthermore, the fixed valve disc is provided with a plurality of protrusions, and the inner valve core body is provided with a corresponding number of grooves. The fixed valve disc is installed in the inner valve core body, and the protrusions cooperate with the grooves.
[0007] Furthermore, the faucet valve core also includes a clamping piece, an annular groove is opened on the rotating rod, the annular groove is flush with the top of the inner valve core body, and the clamping piece is arranged on the top of the inner valve core body and is clamped into the annular groove.
[0008] Furthermore, the outer valve core body is fixedly connected to the inner valve core body, and the top of the outer valve core body is flush with the top of the inner valve core body.
[0009] Furthermore, the outer valve core body is made of cast iron or steel, and the inner valve core body is fixed inside the outer valve core body by plastic casting.
[0010] The present invention provides a faucet valve core with a split valve core body, comprising an outer valve core body and an inner valve core body, the inner valve core body being constructed of plastic. A sealing ring on the rotating rod contacts the inner valve core body, and the rubber material of the sealing ring contacts the plastic material of the inner valve core body. This prevents failure over time and maintains a good sealing effect. Furthermore, the split outer and inner valve core bodies reduce the use of cast iron and lower production costs.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0018] like Figure 1-4 As shown, a faucet valve core is provided, characterized in that the faucet valve core includes a rotating rod 1, an outer valve core body 2, an inner valve core body 3, a movable valve plate 4 and a fixed valve plate 5; the inner valve core body 3 is inserted into the outer valve core body 2, the rotating rod 1 is inserted into the inner valve core body 3, and a sealing ring is provided between the inner valve core body 3 and the rotating rod 1; the movable valve plate 4 and the fixed valve plate 5 are arranged in sequence inside the inner valve core body 3; the rotating rod 1 drives the movable valve plate 4 to rotate; the inner valve core body 3 is made of plastic.
[0019] In this embodiment, the valve core is designed as a split body, consisting of an outer valve core body 2 and an inner valve core body 3, with the inner valve core body 3 being made of plastic. The sealing ring on the rotating rod 1 contacts the inner valve core body 3, and the rubber material of the sealing ring contacts the plastic material of the inner valve core body 3. This prevents failure over long-term use and maintains a good sealing effect. Furthermore, the separation of the outer valve core body 2 and the inner valve core body 3 reduces the amount of cast iron used, lowering production costs.
[0020] Preferably, the faucet valve core also includes a water-sealing sleeve 6, which is disposed at the bottom of the inner valve core body 3 and supports the fixed valve disc 5. The water-sealing sleeve 6 is made of rubber. Inserted into the bottom of the inner valve core body 3, the water-sealing sleeve 6 secures the fixed valve disc 5 within the valve core. Furthermore, the rubber water-sealing sleeve 6, serving as the valve core base, improves the tightness of the connection between the valve core and the base of the valve core within the faucet.
[0021] Preferably, the fixed valve disc 5 is provided with a plurality of protrusions, and the inner valve core body 3 is provided with a corresponding number of grooves. The fixed valve disc 5 is installed in the inner valve core body 3, and the protrusions and the grooves cooperate with each other. The cooperation between the protrusions and the grooves plays a role in limiting and positioning, and facilitates the installation of the fixed valve disc 5 into the inner valve core body 3.
[0022] Preferably, the faucet valve core further includes a clamping member 7. An annular groove 8 is formed on the rotating rod 1, flush with the top of the inner valve core body 3. The clamping member 7 is disposed on the top of the inner valve core body 3 and engages within the annular groove 8. The rotating rod 1 is installed by inserting the inner valve core body 3 from the bottom up, so that the top of the rotating rod 1 extends out of the inner valve core body 3. To secure the rotating rod 1, this embodiment provides an annular groove 8 on the rotating rod 1 and secures it with the clamping member 7.
[0023] Preferably, the outer valve core body 2 is fixedly connected to the inner valve core body 3, and the top of the outer valve core body 1 is flush with the top of the inner valve core body 3. The outer valve core body 2 is made of cast iron or steel, and the inner valve core body 3 is fixed inside the outer valve core body 2 by plastic casting.
[0024] Installation method: The outer valve core body 2 and the inner valve core body 3 are combined into one by casting, and the rotating rod 1 is installed into the inner valve core body 3 from bottom to top, so that the top of the rotating rod 1 extends out of the inner valve core body 3, and the annular groove 8 of the rotating rod 1 is connected with the clamping part 7 to fix the rotating rod 1; the dynamic valve disc 4 and the fixed valve disc 5 are installed in the inner valve core body 3 in sequence, and the fixed valve disc 5 is fixed in the inner valve core 3 with the water sealing sleeve 6.
[0025] Working principle: When working, rotate the rotating rod 1, and the end of the rotating rod 1 drives the movable valve plate 4 to rotate, thereby increasing or decreasing the water passage between the movable valve plate 4 and the fixed valve plate 5, thereby controlling the water flow.
[0026] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
