2. The traditional quick-opening valve core is generally provided with two grooves on a valve rod and sealed by an O-shaped sealing ring, so that the part of the valve rod below the sealing ring is soaked in water for a long time in the using process, and the valve rod is easily oxidized to influence the service life.
3. Two shifting forks for positioning switch water are designed on a valve rod used by a traditional quick-opening valve core, and the two shifting forks are very difficult to process and very high in processing cost for metal materials with high hardness, so that the whole product is high in cost and difficult to popularize.
4. The traditional valve core is generally sealed by adopting an independent silica gel pad between the valve core and a faucet body, and in order to improve the sealing effect of silica gel, a plastic framework is added on the silica gel structure, which runs counter to the limit plastic order issued by the state.
