Water faucet capable of water inlet and outlet from valve core inside

Abstract

The invention relates to a water tap in a valve core for water flow and water in, comprising a tap and a valve core arranged in a three-way channel of the tap. The valve core consists of a septum, a fixing plate, a moving plate, a valve rod, a rotation limiting plate, and a gland cap that are sequentially connected; the moving plate is driven by the valve rod and can rotate in a space confined by the rotation limiting plate, and the other parts are fixed on a side wall of the channel; the septum and the fixing plate are both provided with an axial water inlet hole and an axial water outlet hole that are separated with a separating strip and respectively and correspondingly communicated with each other; the side of the moving plate neighboring to the fixing plate is provided with an axial water inlet trough and an axial water outlet trough that are separated with the separating strip , and the separating strips of the moving plate and the fixing plate can rotate with the moving plate and overlap or interlace; the water inflow channel and the water outlet channel are respectively communicated with a water inflow hole and a water outlet hole of the separating plate through the water inflow mouth and the water outlet mouth that are respectively arranged beside the axial direction of the water inflow hole and the water outlet hole of the septum. The invention can control water flow to flow in and flow out through the interior of the valve core in a direction parallel the axial line, thus overcoming the disadvantages of the existing water tap of too much sealing surfaces, being easy to seep and be oxidated and less water flow, etc.

Description

Technical field [0001] The invention relates to a faucet, in particular to a faucet with water in and out of a valve core. Background technique [0002] At present, the universal quick-opening faucet valve core on the market basically adopts the structure of axial water in the valve core and radial water out of the side wall. This structure makes the inner wall of the three-way channel of the faucet and the outer wall of the valve core full of water when the water is discharged. Therefore, this structure requires multiple sealing rings (such as between the gland cap and the channel wall, between the channel water inlet and the valve core water inlet, between the valve core rod and the rotating surface of the valve core seat) to avoid water leakage. On the one hand, it reduces the sealing performance and increases the complexity and difficulty of installation and processing. On the other hand, the sealing ring is prone to oxidize and cause water leakage when it is used for a long ...

Problems solved by technology

[0002] At present, the common quick-opening faucet spools on the market basically adopt the structure of axial water inlet inside the spool and radial water outlet on the side wall. , so the structure needs to use multiple sealing rings (such as between the gland cap and the channel wall, between the channel water inlet and the valve core water inlet, between the valve core rod and the rotating surface of the valve core seat) to avoid water leakage. On the one hand, it reduces the sealing performance and increases the complexity and difficulty of installation and processing. On the other hand, the sealing ring is easy to oxidize and cause water leakage after a long time of use.

In addition, because the switch part of this faucet uses two contact surfaces with butterfly holes to rotate relative to each other to achieve on-off, the friction contact surface of the switch is large, which not only limits the size of the hole for water in and out, but also makes the water in and out It is small, and when the faucet is turned on and off, it will wear a lot, and it is easy to scratch the friction surface due to impurities in the water, which will affect the water quality and even cause water leakage.
