Legend description:

1. an on-off control tube; 2. an outlet; 3. an inlet structure; 4. sealing the rubber ring; 5. a ring plate; 6. a spring; 7. a filter screen; 8. a chute; 9. a sliding block.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples:

referring to fig. 1-2, the utility model provides a valve core of a stop valve, which comprises an on-off control pipe 1, wherein an outlet 2 is formed in one side of the bottom of the on-off control pipe 1, an inlet structure 3 is integrally communicated with the opposite side of the on-off control pipe 1 and the outlet 2, the inlet structure 3 is positioned above the outlet 2, a sealing rubber ring 4 is embedded and mounted at the upper end of the on-off control pipe 1, a ring plate 5 is integrally arranged in the inlet structure 3, a spring 6 is fixedly mounted on the ring plate 5 towards the outer opening surface of the inlet structure 3, and a filter screen 7 is fixedly mounted at the end part of the spring 6.

Specifically, as shown in fig. 1, the inner side of the inlet structure 3 located on the annular plate 5 is an oblique shrinkage structure, the outer side of the inlet structure 3 located on the annular plate 5 is a tubular structure, the water outlet end of the inlet structure 3 is kept consistent with the size of the outlet 2, meanwhile, the filter screen 7 is convenient to install, the filtering surface of the filter screen 7 is large, and attached filter materials can be shared.

Specifically, as shown in fig. 1, the tubular portion of the inlet structure 3 is provided with a chute 8 around the axis, the edge of the filter screen 7 is raised to form a sliding block 9, and the sliding block 9 is slidably mounted at the chute 8, so that the filter screen 7 can only move forward and backward when being impacted by water, and is relatively stable.
