Abstract

A water level self-closing valve that can be automatically closed when the water storage container is full is composed of a valve body and a casing with an upper cover, the valve body is vertically installed on the upper cover, and is hung outside the water storage container when in use , connected in series in the pipeline, has the characteristics of small size and easy installation.

Description

Water level self-closing valve

The utility model relates to a water level self-closing valve which can be automatically closed when the water storage container is full.

The known water level self-closing valve is also called float valve. When in use, it is installed horizontally on the side wall of the water storage container. A rod is fixed on the small shaft below the valve body. One end of the rod is equipped with a floating ball, and the other end is bent. Finally press on the fulcrum of the spool, when the water level rises, the floating ball presses the fulcrum of the spool through the support rod, so that the spool produces horizontal displacement and closes the valve.

This structure can only be directly installed and used in the water storage container due to its large volume, but cannot be installed and used in the container of airtight water storage.

The purpose of this utility model is to provide a small volume, which is installed in a special shell to form a separate part, which is connected in series in the water supply pipeline when in use, and can be suspended outside the airtight water storage container. valve.

The purpose of this utility model is achieved in that the valve body and the housing with the upper cover together form a part, the valve body is vertically fixed on the upper cover, and the upper part of the housing is in the same position as the valve body when the floating ball is in a horizontal position. The length of the outer shape is the maximum diameter. The lower part of the shell is made into an inverted conical shape with the arc-shaped trajectory when the floating ball falls. In order to increase the bonding area with the water storage container, the middle part of the shell is pressed with an arc-shaped groove. , the upper cover is equipped with a bracket, which is suspended on the upper part of the water storage container when in use, and in order to further reduce the volume, the small shaft of the fixed pole is designed to the side of the valve body close to the shell, so that the fulcrum of the valve core falls on the small shaft Between the float and the ball, the length of the pole is effectively shortened.

Due to the adoption of the above scheme, the overall size and movement space are reduced, so that it can be installed in a special casing, connected in series in the pipeline during use, and hung outside the water storage container, which is convenient to use.

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is a schematic sectional view of the utility model.

Fig. 2 is an embodiment of the utility model.

In Figure 1 1. Valve body 2. Nut 3. Upper cover 4. Valve core 5. Small shaft 6. Shell 7. Strut 8. Floating ball 9. Water outlet joint 10. Faucet

The part shown by the dotted line in Fig. 2 is a closed water storage container, and the part shown by the solid line is 11. the bracket 12. the arc-shaped groove on the housing.

In the structure shown in Figure 1, it is mainly composed of a valve body 1 with a floating ball 8, a rod 7, a valve core 4, and a housing 6 with an upper cover 3. The valve body 1 is covered by a nut 2 It is vertically fixed on the upper cover 3, one end of the pole 7 is fixed on the small shaft 5 under the valve body 1, and the other end is fixed on a floating ball 8, and the fulcrum of the valve core 4 is pressed against the floating ball 8 of the pole 7 and the small shaft 5. The position between the axis and .

Fig. 2 is an embodiment of the utility model, a support 11 is housed on the upper cover 3, and is fixed on the top of the water storage container during use, and the housing 6 is an inverted conical shape, and an arc-shaped groove 12 is pressed in the middle, for use When sticking on the outer wall of the water storage container, the lower part of the housing 6 has a water outlet joint 9 to connect with the water storage container, so that the housing 6 and the water storage container form a communicator. When the water surface in the water storage container is at the lower position, the housing The water surface in 6 is also at the lower position, the floating ball 8, the support rod 7 and the valve core 4 are also at the lower position, and the valve is in the open state. After the tap water enters from the upper part of the valve body 1, it is discharged from the water nozzle 10, and is injected into the housing 6 first. Then flow into the water storage container from the water outlet joint 9 at the bottom of the housing 6, and when the water in the water storage container was full, the water in the housing 6 floated and the floating ball 8 drove the pole 7 to lift the spool 4 upwards. Make the valve close.
