Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet valve core that is anti-reverse installation. Background Art

[0002] Traditional faucets are equipped with control components for controlling water flow and temperature. The control components are usually composed of accessories such as a steering seat, a valve stem, an eccentric seat, a ceramic cover, and a ceramic seat. There are many accessories, and it is very easy to install them in reverse during installation. Usually, the steering seat, eccentric seat and ceramic cover are rotated and installed in reverse, which causes the control component to be unable to discharge water normally. It needs to be disassembled and inspected again, wasting manpower and material resources. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the present invention is: an anti-reverse installation faucet valve core, including a valve seat and a valve cover connected to each other, and a control component arranged in the valve seat, the valve seat is provided with a water outlet, and a hot water inlet and a cold water inlet arranged on both sides of the water outlet, the control component includes a steering seat, a valve stem, an eccentric seat, a ceramic cover, a ceramic seat and a sealing ring distributed in sequence from top to bottom, the steering seat is rotatably connected to the valve cover, the steering seat is connected to the valve stem for controlling the opening and closing of the valve core through a pin, the valve stem is clamped with the eccentric seat, and the eccentric seat is clamped with the eccentric seat. There is a ceramic cover for controlling the temperature of the water outlet, and the ceramic seat is sealed to the valve seat by a sealing ring. The ceramic seat is provided with a center hole, a first special-shaped hole, and a second special-shaped hole corresponding to the water outlet, the hot water inlet, and the cold water inlet. The ceramic cover is provided with a control groove for controlling the connection between the center hole and the first special-shaped hole / the second special-shaped hole. The valve cover is provided with an upper block and a lower block for preventing reverse installation. Limit blocks for abutting the upper block / lower block are provided on both sides of the steering seat. The lower block is provided with a first protrusion for limiting the movement of the eccentric seat, and the eccentric seat is slidably connected to the first protrusion.

[0004] By adopting the above technical solution, when the steering seat is rotated and installed in reverse, the steering seat cannot be stuck in the valve cover through the limitation of the upper block and the lower block. When the eccentric seat is rotated and installed in reverse, the upper surface of the eccentric seat abuts against the first protrusion, so that the valve cover and the valve seat are installed in place, thereby preventing the control component from being installed in reverse and improving production efficiency.

[0005] The utility model is further configured as follows: the steering seat is provided with a rectangular groove for accommodating the valve stem, a pin hole passing through the rectangular groove, and side planes and arc surfaces located on the upper and lower sides of the rectangular groove; the valve stem is rotatably connected to the rectangular groove through the pin hole; the lower stopper is provided with an arc groove corresponding to the arc surface; the distance H from the side plane to the axis is greater than the distance h from the arc surface to the axis; when the steering seat is rotated in reverse, one side of the side plane will interfere with the upper stopper, making it impossible for the steering seat to be installed in place with the valve cover, thereby achieving the effect of preventing reverse installation.

[0006] The utility model is further configured such that a first rectangular cavity adapted to the first protrusion is provided on one side of the eccentric seat, and the eccentric seat is slidably connected to the valve cover through the first rectangular cavity. When the eccentric seat is reversed, the first protrusion cannot be inserted into the first rectangular cavity, resulting in a gap between the valve cover and the valve seat, so that the installation method of the valve cover and the eccentric seat is unique, which has the effect of preventing reverse installation. At the same time, when the valve stem controls the eccentric seat to move linearly, the first protrusion prevents the eccentric seat from rotating, thereby improving the stability of the valve core transmission assembly.

[0007] The utility model is further configured such that the eccentric seat is provided with a second protrusion distributed in an isosceles triangle, and the ceramic cover is provided with a second rectangular cavity corresponding to the second protrusion, and two groups of second protrusions are provided on one side of the first rectangular groove, so that the installation method of the eccentric seat and the ceramic cover is unique, that is, if the eccentric seat is installed correctly, the ceramic cover is also installed correctly, thereby improving the qualified rate of the installation.

[0008] The utility model is further configured such that the valve seat is respectively provided with card slots around it, the valve cover is provided with card blocks corresponding to the card slots, and a first positioning strip and a second positioning strip for preventing reverse installation. The length of the first positioning strip is greater than that of the second positioning strip. The valve cover is connected to the valve seat by the first positioning strip and the second positioning strip of different lengths, so that the connection method between the valve cover and the valve seat is unique, thereby avoiding the phenomenon of reverse installation.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] When the steering seat is rotated and installed in reverse, the steering seat cannot be stuck in the valve cover due to the limitation of the upper stop block and the lower stop block. When the eccentric seat is rotated and installed in reverse, the upper surface of the eccentric seat abuts against the first protrusion, so that the valve cover and the valve seat are installed in place, thereby preventing the control component from being installed in reverse and improving production efficiency.

The ceramic cover 7 is provided with a control groove 71 for controlling the connection between the center hole 14 and the first special-shaped hole 15 / the second special-shaped hole 16. The control groove 71 is in the shape of a water drop. The valve cover 2 is provided with an upper stopper 21 and a lower stopper 22 for preventing reverse installation. Limit blocks 41 for abutting the upper stopper 21 / the lower stopper 22 are provided on both sides of the steering seat 4. The lower stopper 22 is provided with a first protrusion 23 for limiting the movement of the eccentric seat 6, and the eccentric seat 6 is slidingly connected to the first protrusion 23.

[0023] Combine Figure 4-6As shown, in this embodiment, the steering seat 4 is provided with a rectangular groove 42 for accommodating the valve stem 5, and a pin hole 43 passing through the rectangular groove 42, and a side plane 44 and an arc surface 45 located on the upper and lower sides of the rectangular groove 42.
