Description

Technical Field

[0001] The utility model relates to a valve for controlling the water level in a container, in particular to an intermittent water control valve with a float rigidly connected. Background Art

[0002] The water control valve is a valve used to control the water level in a container. The opening and closing of the water inlet of the valve is controlled by the rise and fall of the float. When the water level in the container reaches the set water level, the float automatically closes the valve flap under the action of buoyancy. When the water in the container is lower than the set water level, the float sinks under the action of its own gravity, the valve flap opens, the valve automatically opens, and water enters the container. The existing water control valve is mainly composed of a valve body, a float chamber and a diaphragm valve core assembly. The lower end of the valve body is provided with a lever to control the opening or closing of the diaphragm valve core assembly. Generally, the installation height of the float is the set water level height. When the water level drops, the float also drops, the lever falls, the valve flap opens, and water enters the container; when the water level rises, the float also rises, and the lever is lifted, the valve flap closes, and water stops entering the container. Since the stroke of the lever is small, the water level in the container will drop a little, and the valve flap will open to replenish water. However, some working conditions require that the water level in the container drop to a certain level before replenishing water. In order to meet the above working conditions, Chinese patent CN111486265A discloses an intermittent automatic water control valve, which uses a first bayonet and a second bayonet to control the valve flap opening lock and valve flap closing lock respectively, and uses the first unlocking inclined guide column and the second unlocking inclined guide column on the rope retaining block to unlock. When the water level drops, the second bayonet locks the top pin. When the water level drops to a certain height or the water is completely drained, the top pin is subjected to downward gravity to unlock the second bayonet. The valve flap is automatically closed after the water level rises to a certain height, and water is replenished only after the water level drops to a certain height or the water is completely drained, which can meet the working conditions. This intermittent automatic water control valve has the following technical defects: in order to achieve the purpose of automatically closing the valve disc after the water level rises to a certain height and replenishing water only after the water level drops to a certain height or the water is completely drained, a first bayonet, a second bayonet, a first unlocking inclined guide column, a second unlocking inclined guide column and other relatively complex structures are set, and a rope is used to connect the float. The structure is relatively large, occupies a large space, and is not suitable for use in smaller containers. In addition, there are also problems of difficulty in processing and high cost.

[0010] The technical solution of the utility model is clearly and completely described below in conjunction with the accompanying drawings.

[0011] like Figures 1-2As shown, an intermittent water control valve with a float rigid connection comprises a valve body 1, a lever 2 for controlling the opening or closing of a diaphragm valve core assembly is provided at the lower end of the valve body 1, a slider seat 3 is connected to the lower end of the valve body 1, a slider 4 capable of sliding up and down is installed on the slider seat 3, a top column 5 corresponding to the lever 2 is provided at the upper end of the slider 4, a rigid guide rod 6 is fixed to the lower end of the slider 4, the rigid guide rod 6 passes through the bottom of the slider seat 3 and can slide up and down relative to the slider seat 3, and the lower end of the rigid guide rod 6 is fixed to a float 7; A delayed inclined guide column 8 is provided on one side of the slider 4, and an inclined section 81 is provided above the delayed inclined guide column 8, and a straight section 82 is provided below the delayed inclined guide column 8. A guide column seat 9 is provided on one side of the slider seat 3, and a bayonet 10 and a spring 11 for pushing the bayonet 10 to move toward the lever 2 are installed in the guide column seat 9. The bayonet 10 has a through hole 12, and the upper end of the delayed inclined guide column 8 is located in the through hole 12. When the bayonet 10 is extended, it can be blocked under the lever 2, and when the delayed inclined guide column 8 moves downward, it can push the bayonet 10 to disengage from the lever 2.

[0012] Due to the adoption of the above technical solution, when there is no water in the container, the float 7 moves downward under its own gravity, the lever 2 falls, the diaphragm valve core assembly is in an open state, and water begins to flow into the container. The float 7 rises with the water level and drives the slider 4 to rise. When the water level reaches a certain height, the top column 5 above the slider 4 lifts the lever 2, so that the diaphragm valve core assembly is closed and water stops flowing in. At the same time, the delayed inclined guide column 8 rises and releases the limit of the bayonet 10. The bayonet 10 pops out and blocks under the lever 2 under the action of the spring 11. When the water level drops, the float 7 drives the slider 4 to drop. At this time, the bayonet 10 blocks the lever 2, and the lever 2 cannot fall. The diaphragm valve core assembly is still in a closed state. The float 7 continues to drop and drives the delayed inclined guide column 8 to drop. When the inclined section 81 above the delayed inclined guide column 8 enters the through hole 12, it pushes the bayonet 10 to disengage from the lever 2, and the lever 2 can fall. The position of the lowest water level can be adjusted by setting the length of the straight section 82. The utility model adopts a float rigid connection structure, cancels the complex structures such as the first bayonet, the second bayonet, the first unlocking inclined guide column and the second unlocking inclined guide column, and sets a delayed inclined guide column 8, simplifies the float structure, occupies a small space, is easy to process and has a low cost.

[0013] The side wall of the slider seat 3 is provided with a vertical guide groove 13, the slider 4 and the delay oblique guide pillar 8 are an integral structure, and the lower end of the delay oblique guide pillar 8 is located in the guide groove 13. When the slider 4 moves up and down, the delay oblique guide pillar 8 can slide up and down in the guide groove 13.
