Description

Split ceramic-sealed high-pressure-resistant quick-opening valve core

Technical Field

The utility model belongs to the technical field of the valve, more specifically relates to a high pressure resistant quick-opening valve core that split type valve rod is not water ceramic direct seal excessively.

Background

The existing quick-opening valve core mainly comprises a valve rod, a valve core main body, a ceramic movable sheet, a ceramic static sheet, a valve rod lubricating gasket, a valve rod O-shaped sealing ring, a main body O-shaped sealing ring, a sealing silica gel pad and a silica gel pad.

Such a cartridge has a number of drawbacks:

1. because the traditional silica gel pad is used, the silica gel is soft, and the silica gel used in the traditional valve core is thicker, although the silica gel pad is additionally arranged, the product is easy to leak because of the deformation of the silica gel under the condition of high pressure, and particularly under the condition of reverse water inlet, the situation is more easy to occur and is more serious, so the pressure resistance of the traditional valve core is very limited.

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.

At present, the existing related research is relatively lack due to the fact that a plurality of problems such as a plurality of uncertain factors are caused by the fact that application scenes are relatively few and accurate information is difficult to obtain.
