Description

Technical Field

[0001] The invention relates to the technical field of angle valves, and in particular to a quick-opening angle valve with adjustable gear positions. Background Art

[0002] The valve is a control component in the fluid delivery system and is widely used in sanitary ware. Its function is to control the opening and closing of cold water, hot water and mixed water, and it can switch between each other and control the size of the water flow under the water supply state. As an important plumbing accessory, the angle valve is mainly used to switch the internal and external water outlets, adjust the water pressure and switch the leakage. At present, the angle valves on the market generally have ceramic moving plates and ceramic fixed plates at the bottom of the valve stem to control the size of the water flow. However, even if this structure is opened to the maximum, the water flow is limited, and a gasket is usually set between the ceramic moving plate and the valve stem to reduce the water from the gap between the valve stem and the valve core sleeve. However, the existing gaskets are made of plastic. Plastic materials are easily worn and deformed during use. The deformed gasket may cause water to seep through the gap between the upper end of the valve core sleeve and the valve stem, resulting in leakage, and the use effect is poor. Although there are valve cores that use threaded rotation control to achieve large water flow, the valve core of this structure has a slow opening speed and cannot meet the use requirements. In addition, only the closed and open gears can be accurately selected, and other gears cannot be accurately selected to adjust the water flow. It cannot meet the multi-gear selection in the market, especially for kitchen water, which requires higher control of water flow. Valves without gear selection are very likely to cause waste of water resources. Summary of the invention

[0008] Furthermore, in order to achieve the quick opening function, shorten the stroke, and improve the structural strength of the valve core and the valve stem; there are two push rods, which are symmetrically arranged on the valve stem, and there are two corresponding abutment tops, which are centrally symmetrically arranged on the valve core.

[0009] Furthermore, in order to guide the water sealing member to move up and down in the water inlet pipe and avoid displacement deviation at the water outlet control port, the height of the water sealing member is greater than the diameter of the water outlet control port.

[0010] Furthermore, in order to limit the upward movement distance of the water sealing component and ensure that the installation structure of the spring component can realize the reset function; a limit seat is provided in the valve body, which is located in the water inlet pipe and above the water outlet control port. The distance between the limit seat and the upper end surface of the water outlet control port is greater than the height of the water sealing component, and the lower end of the spring component is connected to the upper side surface of the limit seat.

The rod diameter of the connecting rod is smaller than the diameter of the valve core, and the spring component is sleeved on the connecting rod.

[0012] Furthermore, in order to prevent the valve stem from rotating and driving the valve core to rotate, and to ensure the up and down movement of the valve stem, a stopper is provided between the valve core and the connecting rod, and the cross-section of the stopper is a cross-shaped structure, and a stopper is provided in the valve body, and the stopper extends radially inward from the side wall of the valve body and abuts against the stopper to limit the rotation of the valve core.
