Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and specifically relates to a ball valve. Background Technology

[0002] A ball valve is a valve in which the ball is driven by the valve stem and rotates around the axis of the ball valve. It can be used for the regulation and control of fluids.

[0003] However, existing ball valves have the following drawbacks: 1. Although existing ball valves can control the flow of water, impurities contained in the water will flow out with the water. Existing ball valves cannot effectively filter impurities in the water, and a large amount of impurities flowing through the ball valve cannot be processed.

[0004] 2. Most existing ball valves are simply designed. Even if they are equipped with filters to remove impurities, they cannot effectively remove the impurities adhering to the filters quickly. Most of the time, the ball valve needs to be opened manually to clean the impurities, which is cumbersome, time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a valve with a filtering function.

[0006] The objective of this utility model can be achieved through the following technical solution: A ball valve, comprising a valve body, a flow channel provided inside the valve body, and a valve ball for controlling the flow channel provided inside the valve body, characterized in that a mounting base is provided at the lower end of the valve body, and a filtering device for filtering is provided between the valve ball and the mounting base, the filtering device comprising a fixing frame and a positioning frame, the positioning frame having a plurality of water passage holes for water passage, and a filter screen being installed on each water passage hole, the lower end of the valve ball having a slot for mounting the fixing frame, a plurality of ball bearings being provided on the side wall of the slot, a sliding groove for the ball bearings to slide left and right being provided inside the valve ball and relative to each ball bearing, a positioning ring being provided on the mounting base, the positioning ring extending into the valve ball and fixing the filtering device inside the valve ball by the action of the ball bearings, and a snap-fit ​​groove for the ball bearings to snap into the outer wall of the fixing frame.

[0007] In the ball valve described above, the positioning ring and the mounting base are integrally formed, and the valve ball has a groove for the positioning ring to extend into.

[0008] In one of the ball valves described above, the upper end of the valve ball is provided with a positioning groove for fixing a positioning frame. One end of the positioning frame is connected to the fixing frame, and the other end extends into the positioning groove at the upper end of the valve ball.

[0009] Compared with existing technologies, this valve has a filtering effect by incorporating a filter device inside the valve ball and fixing it with a mounting base. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 As shown, this valve includes a valve body 1, a flow pipe inside the valve body 1, a valve ball 2 for controlling the flow pipe inside the valve body 1, a mounting base 3 at the lower end of the valve body 1, and a filter device 4 for filtration between the valve ball 2 and the mounting base 3. The filter device 4 includes a fixing frame 5 and a positioning frame 6. The positioning frame 6 has several water passage holes for water passage, and each water passage hole is equipped with a filter screen 7. The lower end of the valve ball 2 has a slot for mounting the fixing frame 5. Several balls 8 are provided on the side wall of the slot. The valve ball 2 has a sliding groove for the balls 8 to slide left and right relative to each ball 8. The mounting base 3 has a positioning ring 9. The positioning ring 9 extends into the valve ball 2 and fixes the filter device 4 inside the valve ball 2 through the action of the balls 8. The outer wall of the fixing frame 5 has a snap-fit ​​groove for the balls 8 to snap into place.

[0014] To elaborate further, when the flow channel inside the valve ball 2 is in a flow state, the liquid passes through the flow channel inside the valve ball 2 and is filtered by the filter screen 7 of the positioning frame 6 inside the valve ball 2, thereby purifying the water source.

[0015] To elaborate further, when installing the filter device 4, the mounting bracket 5 is installed in the slot of the valve ball 2, and then the mounting seat 3 at the lower end of the valve body 1 is installed. The positioning ring 9 on the mounting seat 3 extends into the groove and pushes the ball 8 towards one side of the mounting bracket 5. One side of the ball 8 is in contact with the side wall of the positioning ring 9, and the other side extends into the snap-fit ​​groove of the mounting bracket 5, thereby fixing the mounting bracket 5. The setting of the fixing ring enhances the sealing between the valve ball 2 and the mounting seat 3.

[0016] To elaborate further, the positioning ring 9 and the mounting base 3 are integrally formed, and the valve ball 2 has a groove for the positioning ring 9 to extend into.

[0017] To elaborate further, the upper end of the valve ball 2 is provided with a positioning groove for fixing the positioning frame 6. One end of the positioning frame 6 is connected to the fixing frame 5, and the other end extends into the positioning groove at the upper end of the valve ball 2.

[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0019] Although this document frequently uses terms such as valve body 1, valve ball 2, mounting base 3, filter device 4, fixing frame 5, positioning frame 6, filter screen 7, ball bearing 8, and positioning ring 9, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
