Poking rod control type valve core

Abstract

The invention discloses a poking rod control type valve core. The poking rod control type valve core comprises a base and a valve body, wherein a poking rod, a support, a poking disc, a ceramic rotor plate and a ceramic stator plate are sequentially arranged in the valve body from top to bottom, a containing hole is formed in the poking disc, the ceramic rotor plate is fixedly connected with the poking disc, the ceramic stator plate is fixed on the base, the bottom end surface of the base is provided with two water inlet passages which axially penetrate through the base, the side wall of the base is provided with a water outlet passage which stretches to the upper end surface of the base, water holes which correspond to the water inlet passages and the water outlet passage are formed in the ceramic stator plate, and a concave cavity which corresponds to the water holes in the ceramic stator plate is formed in the ceramic rotor plate; the poking rod is connected to the support in a pivoting way, the lower end of the poking rod stretches into the containing hole of the poking disc, the ceramic rotor plate is driven to move through the poking disc by the poking rod, and communicating or opening and closing states between the concave cavity in the ceramic rotor plate and the water holes can be realized; water inlet pipe connectors which are provided with threads are embedded into the water inlet passages, and the water outlet passage is a plastic threaded hole which is connected with a standard hose, so that water flow cannot pass through a faucet main body, and the requirement on the faucet main body is low.

Description

technical field [0001] The invention relates to a lever-controlled valve core. Background technique [0002] The bottom structure of the spool used in the sanitary ware industry is sealed with the main body of the faucet through a gasket. At the same time, the main body of the faucet needs to be connected to the water inlet hose through a threaded joint, and the water flows out through the main body of the faucet. As a result, the structure of the faucet will be relatively complicated, resulting in difficult casting, a high defect rate, a large amount of processing work, and high cost. [0003] In addition, in order to ensure the sealing, this requires high processing accuracy for the main body of the faucet; and in order to ensure the water quality, the requirement for the precipitation of metal pollutants on the inner surface of the main body of the faucet in contact with water is also relatively high. [0004] To sum up, the spool used in the traditional technology not o...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the spool used in the traditional technology not only makes the structure of the main body of the faucet complex and difficult to manufacture, but also has high requirements on the accuracy and material of the main body of the faucet, which ultimately leads to high costs.
