Valve element assembly

Abstract

The invention relates to a novel valve element assembly. The valve element assembly alone has main functions such as the water controlling function, the water guiding function, the support function and the like of a water faucet, thereby enabling the shell (the body) of the faucet to be unnecessary to be in contact with water flow and is used only for configuration decoration. The valve element assembly mainly comprises a pedestal, valve plates, a valve element pressing cap and an extended water guiding hose, and optionally comprises an added component (a filter, an electric heater or the like) at a water outlet end of the valve element assembly or the like. The valve plates (or together with the valve element pressing cap) control the water flow and form an independent sealed water channel, and the functions of switching and changing the water flow can be realized by only using movable valve plates to seal a switching rotating shaft between water inlet valve plates and water outlet valve plates. The water flow is guided to the faucet through the connection of the extended water guiding hose and a water outlet of the valve element assembly (or a water outlet of the added component)and flows out. To add multiple functions and meet other design requirements, the added component (such as, the filter, the electric heater or the like) can be additionally connected to the water outlet end of the valve element assembly. Then a water outlet of the same type (a lug boss type water outlet or a connection hole type water outlet) is designed on the added component, which facilitates the connection with the extended water guiding hose. The valve plates are designed into tri-dimensional valve plates, planar valve plates and double acting valve plates, all of which are applicable toa bathroom faucet and a basin faucet.

Description

technical field [0001] The invention belongs to a valve core assembly of a mechanical faucet product. Background technique [0002] The faucet spools disclosed in the market generally just switch the water flow. There are several defects in this product: [0003] 1. Since the valve core only switches the water flow, it has no diversion function. Therefore, the faucet body or other parts must contact the water flow, making the design and processing of these parts quite difficult. [0004] 2. The rotational torque is too long, so that the moment arm parts of the spool are under too much force and are easily damaged. [0005] 3. Plastic housing parts for ceramic chips. Water pressure is very limited. [0006] 4. The two water inlet holes of the water inlet valve plate are located side by side, so that the rotation angle of the moving valve plate is too large, and the valve plate is easy to wear. [0007] 5. The water inlet and outlet of the valve core are connected with t...

Problems solved by technology

So the faucet body or other parts must contact the water flow, making the design and processing of these parts quite difficult

[0004] 2. The rotation torque is too long, so that the arm parts of the spool are under too much force and are easily damaged

Can withstand water pressure very limited

[0006] 4. The two water inlet holes of the water inlet valve are located side by side, so that the rotation angle of the moving valve is too large, and the valve is easy to wear

Gasket aging is prone to water leakage
