Pressing valve and water discharging faucet

Abstract

The invention discloses a pressing valve and a water discharging faucet. The pressing valve comprises a valve shell, a valve rod and a pressing assembly, the valve rod is driven by the pressing assembly to slide between a first position and a second position in the axial direction of the valve shell so as to switch the water discharging state or the water filling state of the valve shell, and thevalve rod is provided with two sets of pressure bearing structures in the axial direction of the valve rod. Each set of pressure bearing structures comprises two pressure bearing surfaces which are oppositely arranged and have the same pressure-bearing area; and when the valve rod is positioned at the first position or the second position, the corresponding set of pressure bearing structures bearwater. By adopting the pressing valve and the water discharging faucet with the structure, the pressure of water pressure on the valve rod can form balance, so that the resistance during pressing operation is reduced, and the pressing hand feeling of the pressing valve is ensured.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a push valve and a water outlet faucet. Background technique [0002] Existing push valves generally include a valve housing, a valve stem, a diaphragm, and a push assembly. The push assembly is usually a ballpoint pen press structure. Through the cooperation of the ratchet and ratchet teeth, the ratchet is pushed to rotate at a certain angle and stops at two positions when pressing. Between, so that the valve stem can be positioned at the preset position, the pilot hole is set on the diaphragm, and the water flow is pre-injected through the pilot hole to make the water pressure of the chambers on both sides of the diaphragm consistent, thereby reducing the resistance when pressing , to ensure the pressing feel, but this kind of pilot-operated pressing valve is prone to failure due to the blockage of the pilot hole, and it is impossible to switch the waterway. In order to solve th...

[0002] Existing push valves generally include a valve housing, a valve stem, a diaphragm, and a push assembly. The push assembly is usually a ballpoint pen press structure. Through the cooperation of the ratchet and ratchet teeth, the ratchet is pushed to rotate at a certain angle and stops at two positions when pressing. Between, so that the valve stem can be positioned at the preset position, the pilot hole is set on the diaphragm, and the water flow is pre-injected through the pilot hole to make the water pressure of the chambers on both sides of the diaphragm consistent, thereby reducing the resistance when pressing , to ensure the pressing feel, but this kind of pilot-operated pressing valve is prone to failure due to the blockage of the pilot hole, and it is impossible to switch the waterway. In order to solve this problem of the pilot-operated pressing valve, there is a direct use of pressing components to push the valve stem The push valve structure slides to switch the waterway, but this structure leads to the need to overcome the water pressure when pressing, resulting in poor pressing feel
