Description

Technical Field

[0001] The utility model relates to the technical field of valve core installation, in particular to a valve core pre-installed component. Background Art

[0002] In water outlet equipment, such as faucets and shower controllers, the valve core is an indispensable and important component. For the installation of the valve core, a sufficiently deep installation cavity is usually set in the main body of the water outlet equipment for the valve core to be fully installed, leaving only the valve stem to extend out, and finally, the valve core is pressed by screwing the pressure ring into the opening of the installation cavity. The traditional valve core installation structure has the following problems: 1. In the water flow state, the valve core often bears the hydraulic force at the bottom, and has a tendency to be pushed out of the installation cavity. The thrust may cause the pressure ring to break, so the pressure ring needs to have a higher strength; 2. Some larger water outlet equipment, in order to reduce storage pressure and transportation costs, are often sold in a dispersed manner, and then assembled on-site by users or door-to-door installation masters. However, the dispersed parts will not only cause inconvenience during on-site assembly, but also there is the possibility of insufficient parts, assembly errors and component damage; 3. In the second case, the water flow test of the product needs to be assembled and then completely disassembled, and the testing process is cumbersome. To this end, the utility model provides a valve core installation structure that can solve the above technical problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a modular valve core assembly structure.

[0004] A valve core pre-installed assembly includes a pre-installed seat, a valve core and a pressing piece, wherein:

[0005] The pre-installation seat is provided with a mounting hole, one end of which is a loading port, the other end is a clearance port, and a limiting step is provided in the mounting hole toward the loading port. An assembly structure is provided around one end of the pre-installation seat near the loading port for the pre-installation seat to be installed on the water outlet device for use.

[0006] The valve core is provided with one end of a valve stem which is installed in the mounting hole through the installation port, and the valve stem is exposed through the clearance port and can be connected to an external handle. After being installed in place, the limit step supports the top or periphery of the valve core to limit the valve core from further entering the mounting hole.

[0007] The pressing piece is installed at the loading port of the pre-installed seat and presses the valve core to prevent the valve core from falling out.

[0008] The valve core pre-installed component is installed at the end of the installation cavity of the water outlet device through an assembly structure, and the part of the valve core exposed from the installation inlet extends into the installation cavity of the water outlet device.

[0009] The valve core pre-installed component provided by the utility model can ship the valve core as a module product after preliminary assembly. During on-site assembly, it only needs to install the module on the water outlet equipment, eliminating the assembly process of the valve core and its various supporting small parts, and avoiding the problems of excess parts, assembly errors, and repeated disassembly and assembly after assembly. In addition, the pressing piece provided by the utility model is not subject to the top thrust of the valve core when water is passed, and is not easy to be damaged, so its strength requirement is not high. At the same time, the top thrust of the valve core is transferred to the pre-installed seat with a larger size, and the overall strength is high.

[0010] Preferably, the limiting step is an annular step, and the supporting force is balanced and reliable.

[0011] Preferably, the limiting step has two layers, and the periphery of the valve core is also correspondingly provided with two layers of supporting surfaces, thereby increasing the force-bearing area and reducing the problem of mutual squeezing and damage of the valve core or the pre-installed seat under the action of hydraulic pressure.

[0012] Preferably, in order to guide the installation direction of the valve core during assembly, at least one limiting protrusion is provided in the installation port, and a corresponding limiting notch is provided on the periphery of the valve core.

[0013] Preferably, there are two pairs of limiting protrusions and limiting notches with different sizes, forming a fool-proof structure, which can further avoid the problem of reverse installation of the valve core.

[0014] Preferably, the outer ring of the clearance opening adopts a conical surface, which can reduce the gap formed during the subsequent assembly of the handle.

[0015] Preferably, the assembly structure is a seat body arranged at the end of the pre-installed seat, and the periphery of the seat body is provided with mounting holes and screws, so that the mounting structure is stable and reliable.

[0016] Preferably, a limiting groove is provided at one end of the seat body facing outward, which can avoid the problem of reverse installation when the pre-installed seat is assembled with the water outlet device, and at the same time, it also has the function of preventing rotation.

[0017] Preferably, the end of the valve core exposed from the loading port is provided with a water inlet and a water outlet.

[0018] Preferably, the pressing piece is annular and is assembled in the loading port by means of threads, and has a simple structure.

[0019] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0020] The valve core pre-assembled assembly provided by the utility model can ship the valve core as a module product after preliminary assembly. During on-site assembly, it is only necessary to install the module on the water outlet device, thereby eliminating the assembly process of the valve core and its various supporting small parts, and avoiding the problems of excess parts, assembly errors, and repeated disassembly and assembly after assembly.

[0021] The pressing piece provided by the utility model is not subjected to the top thrust of the valve core when water is passed, and is not easy to be damaged, so the strength requirement thereof is not high. At the same time, the top thrust of the valve core is transferred to the pre-installed seat with a larger size, so the overall strength is high and it is less likely to be damaged;

[0022] The limiting step has two layers, thereby increasing the force-bearing area and reducing the problem of mutual squeezing and damage of the valve core or the pre-installed seat under the action of hydraulic pressure;

[0023] The outer ring of the clearance opening adopts a conical surface, which can reduce the gap formed when the handle is assembled later and prevent the valve stem from being exposed. BRIEF DESCRIPTION OF THE DRAWINGS
