Description

Technical Field

[0001] This utility model is a flat-footed three-hole idling valve core, belonging to the field of valve core technology. Background Technology

[0002] The valve core is a valve component that enables the valve body to perform basic functions such as directional control, pressure control, or flow control by moving its body. According to its shape, it can generally be divided into ball (ball valve), conical (plug valve), disc (butterfly valve and gate valve), round cover type (gate valve and check valve) and cylindrical (directional valve).

[0003] In existing flat-footed three-hole idling valve cores, wear occurs on the dial and the inside of the valve core housing during repeated use, resulting in gaps between the dial and the valve core housing. When the faucet is turned on, water flows out through these gaps, wasting water and causing corrosion to the pins. There is an urgent need for a flat-footed three-hole idling valve core to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a flat-footed three-hole idling valve core to solve the problems mentioned in the background art. This utility model has good practicality. The sleeve covers the bottom of the handle and tightly attaches the waterproof extrusion frame to the surface of the handle. When wear occurs inside the flat-footed three-hole idling valve core housing, creating gaps, the waterproof extrusion frame and sleeve can limit the water flow to the flat-footed three-hole idling valve core housing, preventing water from corroding the pin and avoiding water waste.

[0007] Furthermore, the two sleeves respectively cooperate with the front and rear frustums of the handle.

[0008] Furthermore, the waterproof extrusion frame is made of food-grade silicone material.

[0009] Furthermore, the waterproof elastic layer is made of food-grade elastic material.

[0010] Furthermore, the cover and the handle are connected in conjunction.

[0011] Furthermore, a smooth layer is provided in the circular groove on the upper surface of the dial.

[0012] The beneficial effects of this utility model: This utility model provides a flat-footed three-hole idling valve core.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Please see Figures 1-13This utility model provides a technical solution: a flat-footed three-hole idling valve core, including a flat-footed three-hole idling valve core housing 1, a rotor 4 disposed inside the flat-footed three-hole idling valve core housing 1, a pin 3 passing through and rotatably connected to both ends of the circumference of the rotor 4 and the flat-footed three-hole idling valve core housing 1, a handle 2 fixedly connected to the circumferential surface of the pin 3, a dial 5 slidably connected inside the rotor 4, an upper ceramic plate 6 disposed at the lower end of the dial 5, a flat-footed three-hole idling valve core base 8 fixedly connected to the lower end of the flat-footed three-hole idling valve core housing 1 by a snap-fit ​​block, a lower ceramic plate 7 disposed at the upper end of the flat-footed three-hole idling valve core base 8, small through-tubes 9 fixedly connected to the two small round holes of the flat-footed three-hole idling valve core base 8, and a large round hole of the flat-footed three-hole idling valve core base 8. The inner fixed connection is a large through pipe 10, and the inner walls of the rotor 4 are fixedly connected to an edge connecting frame 13. The middle of the edge connecting frame 13 is fixedly connected to a waterproof elastic layer 14. The upper end of the waterproof elastic layer 14 is fixedly connected to a wrapping sleeve 11. Both the left and right ends of the wrapping sleeve 11 are fixedly connected to sleeves 12. The inner walls of the wrapping sleeve 11 are fixedly connected to waterproof extrusion frames 15. This design solves the problem in the original device where the flat-footed three-hole idling valve core wears down inside the dial 5 and the flat-footed three-hole idling valve core housing 1 during repeated use, resulting in gaps between the dial 5 and the flat-footed three-hole idling valve core housing 1. When the faucet is turned on, water will flow out through the gaps, resulting in water waste and easy corrosion of the pin 3.

[0030] In the first embodiment of this utility model: two sleeves 12 respectively cooperate with the front and rear frustums of the handle 2. By fitting the sleeves 12 around the ends of the handle 2, the fit between the sleeves 12 and the handle 2 is enhanced, preventing water from flowing out from the gap between the handle 2 and the cover 11. The waterproof extrusion frame 15 is made of food-grade silicone material, whose elasticity effectively isolates water flow without affecting it. The waterproof elastic layer 14 is made of food-grade elastic material, which can isolate water flow and deforms according to the swing angle of the handle 2, allowing the cover 11 to fit the handle 2. The cover 11 and the handle 2 are connected and cooperate with each other. By wrapping the handle 2, the cover 11 can prevent water from flowing out from the gap between the handle 2 and the rotor 4, effectively limiting the water source. A smooth layer is provided in the circular groove on the upper surface of the dial 5, increasing the smoothness of the connection between the dial 5 and the handle 2. When the handle 2 swings, the dial 5 can make corresponding displacement according to the pressure.

[0031] As a second embodiment of this utility model: First, when assembling the handle 2 into the rotor 4, the cover 11 needs to be opened first, and then the handle 2 is placed into the cover 11. The two sleeves 12 are respectively fitted onto the protruding frustum surfaces at the front and rear ends of the handle 2. When the user turns on the faucet, the handle 2 will release the dial 5, and then the water pressure will push the upper ceramic piece 6 upward, flowing out through the through hole on the surface of the lower ceramic piece 7. When a gap appears between the dial 5 and the flat-foot three-hole idling valve core housing 1, the water will flow through the gap to the rotor 4. The waterproof elastic layer 14 and the waterproof extrusion frame 15 inside the rotor 4 can block the water flow to prevent overflow.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
