Description

Technical Field

[0001] This utility model is an integrated 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 the existing integrated valve core technology, the pin inside the integrated valve core is affected by the moisture from the faucet during use, which causes corrosion on its surface and makes the pin surface prone to rust. There is an urgent need for an integrated valve core to solve the above-mentioned problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated valve core to solve the problems mentioned in the background technology. This utility model has good practicality. By introducing food-grade lubricating oil into the handle, when the handle is turned to turn on the water source, the lubricating oil will be introduced into the surface of the pin. When the handle is not in use, the rolling sealing ball will restrict the lubricating oil, so that the pin is in a lubricated state.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated valve core, comprising an integrated valve core cover and an integrated valve core shell, wherein a rotor is disposed inside the integrated valve core cover, a pin is fixedly connected inside the circular hole of the rotor, a handle is rotatably connected to the circumferential surface of the pin, a dial is disposed inside the integrated valve core shell, an upper ceramic plate is slidably connected to the lower end of the dial, a lower ceramic plate is fixedly connected to the integrated valve core shell, and an inner sealing ring is fixedly connected to the circular groove inside the lower ceramic plate;

[0006] The handle has a conical groove and a sealing circular groove. The lower inner wall of the conical groove has an oil guide hole. A rolling sealing ball is rotatably connected in the conical groove. A filter screen is fixedly connected in the oil guide hole. Two oil guide ring grooves are formed on the surface of the circular hole of the handle.

[0007] Furthermore, an O-ring is fixedly connected to the lower end of the integrated valve core housing.

[0008] Furthermore, a sealing head is fixedly connected to the threaded surface inside the handle.

[0009] Furthermore, the surface of the rolling sealing ball is provided with a rubber layer.

[0010] Furthermore, the filter screen is made of stainless steel.

[0011] Furthermore, the inner sealing ring and the integrated valve core housing are made of rubber material.

[0012] The beneficial effects of this utility model are as follows: This utility model is a one-piece valve core. Because this utility model adds a conical groove, a rolling sealing ball, a sealing circular groove, a filter screen, an oil guide hole, and an oil guide ring groove, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. By introducing food-grade lubricating oil into the handle, when the handle is turned on to open the water source, the lubricating oil will be introduced into the surface of the pin. When the handle is not in use, the rolling sealing ball will restrict the lubricating oil, so that the pin is in a lubricated state. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] Please see Figures 1-14 This utility model provides a technical solution: an integrated valve core, including an integrated valve core cover 1 and an integrated valve core housing 9. A rotor 4 is disposed inside the integrated valve core cover 1, and a pin 3 is fixedly connected to the circular hole of the rotor 4. A handle 2 is rotatably connected to the circumferential surface of the pin 3. A dial 5 is disposed inside the integrated valve core housing 9, and an upper ceramic plate 6 is slidably connected to the lower end of the dial 5. A lower ceramic plate 7 is fixedly connected to the integrated valve core housing 9, and an inner sealing ring 8 is fixedly connected to the circular groove within the lower ceramic plate 7. The handle 2 has an opening... The conical groove 14 has a sealing circular groove 17 inside the handle 2. The lower inner wall of the conical groove 14 has an oil guide hole 12. A rolling sealing ball 15 is rotatably connected inside the conical groove 14. A filter screen 16 is fixedly connected inside the oil guide hole 12. Two oil guide ring grooves 13 are opened on the surface of the circular hole of the handle 2. This design solves the problem that in the original device, the pin 3 inside the integrated valve core is affected by the moisture of the faucet during use, which will cause corrosion on its surface and make the pin 3 prone to rust.

[0031] As the first embodiment of this utility model: an O-ring 10 is fixedly connected to the lower end of the integrated valve core housing 9. The O-ring 10 installed at the lower end of the integrated valve core housing 9 can increase the sealing performance of the integrated valve core housing 9 and prevent water from flowing out from the gaps. A sealing head 11 is fixedly connected to the threaded surface inside the handle 2, which can block the food-grade lubricating oil, reduce the contact of air with the food-grade lubricating oil, and prevent dust and water from entering the food-grade lubricating oil. The surface of the rolling sealing ball 15 is provided with a rubber layer, which stays on the surface of the sealing groove 17 to prevent food-grade lubricating oil from entering the oil guide ring groove 13. The filter screen 16 is made of stainless steel, which has corrosion resistance and effectively increases service life. The inner sealing ring 8 and the integrated valve core housing 9 are made of rubber material, which can seal the water flow and prevent water leakage.

[0032] As a second embodiment of this utility model: When using the integrated valve core, first pinch the sealing head 11 and unscrew it, then introduce food-grade lubricating oil into the conical groove 14. When the handle 2 stands in the integrated valve core cover 1 and its bottom restricts the dial 5, the rolling sealing ball 15 blocks the sealing circular groove 17 under its own weight, preventing the lubricating oil from flowing out. When the user turns the faucet switch to push the handle 2, the rolling sealing ball 15 will roll towards the surface of the conical groove 14. At the same time, the lubricating oil will flow through the sealing circular groove 17 to the oil guide hole 12, and then move through the oil guide ring groove 13 to evenly coat the surface of the pin 3. When the user turns the faucet switch to reset, the handle 2 will stand in the integrated valve core cover 1, and the rolling sealing ball 15 will roll into the sealing circular groove 17, so that the rolling sealing ball 15 blocks the oil guide hole 12.
