Description

Technical Field

[0001] The present application relates to the technical field of ball valves, and in particular to a ball valve with a filtering function. Background Art

[0002] A ball valve is a valve whose opening and closing member (ball) is driven by a valve stem and rotates around its axis. It can also be used for regulating and controlling fluids. The hard-sealed V-shaped ball valve, with its V-shaped core and carbide-clad metal seat, creates a strong shear force, making it particularly suitable for media containing fibers and tiny solid particles. Multi-way ball valves, on the other hand, can flexibly control the confluence, diversion, and direction of media in pipelines and can also close any channel while connecting the other two. These valves should generally be installed horizontally in pipelines.

[0003] At present, existing ball valves generally have a filtering function, which causes particulate matter in the water flow to remain inside the ball valve after the water flow is transmitted. Long-term accumulation will cause particulate matter to accumulate inside the ball valve, making it difficult for the ball valve to control the effect of the water flow, and even causing blockage inside the ball valve. To this end, we propose a ball valve with a filtering function to solve the above problem. Utility Model Content

[0023] See also Figure 1-4 , this utility model provides a technical solution of a ball valve with filtering function:

[0024] A ball valve with a filtering function includes a valve housing 1, to which a ball 15 is rotatably connected inside the valve housing 1, a through hole 16 is opened on the upper surface of the valve housing 1, and a transmission rod 11 is fixedly connected to the upper surface of the ball 15, and the top of the transmission rod 11 passes through the through hole 16 and extends to the top of the valve housing 1, and the top of the transmission rod 11 is fixedly connected to the operating handle 12, which constitutes the control mechanism of the device, which is convenient for controlling the water flow rate, and a filter housing 2 is provided on the left side of the valve housing 1, and the right side of the filter housing 2 and the left side of the valve housing 1 are fixedly connected with a connecting plate 7, and the two connecting plates 7 are fixedly installed together by bolts on the side close to each other, which is convenient for disassembly of the filter housing 2, thereby facilitating cleaning of the interior, and a group of equidistantly arranged mounting brackets 18 are fixedly connected to the inner wall of the filter housing 2, and a pre-filter bag 19, a high-efficiency filter layer 20 and an activated carbon granular layer 14 are fixedly installed on the left sides of the three mounting brackets 18, respectively, forming the filtering mechanism of the device, so that the ball valve has a filtering function.

[0025] In this embodiment, the right side of the valve housing 1 is fixedly connected to a first flange 8, and the right side of the first flange 8 is fixedly connected to a first sealing gasket 10. The right side of the first flange 8 and the right side of the first sealing gasket 10 are both provided with a group of equidistantly arranged mounting holes 9, which are convenient for installing and fixing the position of the ball valve. The outer surface of the operating handle 12 is fixedly connected to a protective sleeve 13, and the outer surface of the protective sleeve 13 is provided with a group of equidistantly arranged anti-slip grooves to avoid harm to the user during the operation of the control mechanism. The inner wall of the through hole 16 is fixedly connected to a sealing ring 17, and the inner wall of the sealing ring 17 is in contact with the outer surface of the transmission rod 11, thereby enhancing the sealing effect of the device and avoiding water leakage.

[0026] In this embodiment, an indicator mark 5 is fixedly connected to the upper surface of the filter housing 2, and a guide arrow is fixedly connected to the upper surface of the indicator mark 5, which can help users understand the direction of water flow, thereby facilitating the installation of the device. The left side of the filter housing 2 is fixedly connected to a second flange 3, and the left side of the second flange 3 is fixedly connected to a second sealing gasket 4.

[0027] Working principle: When the ball valve with filtering function is used, the user first installs the ball valve using the first flange 8 and the mounting hole 9, and connects the ball valve to the transmission pipe using the second flange 3 and the fixing hole 6. Then, by rotating the operating handle 12, the operating handle 12 drives the transmission rod 11 to rotate through the through hole 16, and the transmission rod 11 drives the ball 15 to rotate, so as to achieve the effect of regulating the water flow rate. Then, when the water flows through the ball 15 and enters the interior of the filter housing 2, the pre-filter bag 19 is used to block the larger particulate matter in the water flow, and the high-efficiency filter layer 20 is used to block the fine particulate matter in the water flow. Finally, the activated carbon granular layer 14 is used to adsorb micromolecules and microorganisms in the water flow. At the same time, the odor in the water flow is adsorbed, so as to achieve the effect of filtering the water flow.
