When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, the anti-blocking ball valve 100 disclosed in the present invention, the anti-blocking ball valve 100 includes: the rotary cleaning valve comprises a valve body 1 penetrating through a pipeline 11, a first connecting pipe 2 and a second connecting pipe 3 respectively arranged at two ends of the pipeline 11, a valve ball 4 arranged between the first connecting pipe 2 and the second connecting pipe 3, a valve rod 5 fixedly connected with the valve ball 4, and a bottom cover 6 arranged at the bottom of the valve body 1, wherein the valve ball 4 is in sealing fit with the first connecting pipe 2 and the second connecting pipe 3, the on-off of the ball valve can be controlled by rotating the valve rod 5, the rotary cleaning valve further comprises a rotary cleaning piece 7 arranged in the valve ball 4 and a driving bevel gear 8 fixedly arranged on the bottom cover 6, the rotary cleaning piece 7 comprises an annular bevel gear 71 and a scraper 72 fixedly connected to the inner side of the annular bevel gear 71, an annular groove 41 is formed in the valve ball 4, the annular bevel gear 71 is arranged in the annular groove 41, and the scraper 72 is attached to the flow passage surface of the valve ball 4, the annular bevel gear 71 is meshed with the driving bevel gear 8, and the driving bevel gear 8 can drive the annular bevel gear 71 to rotate through rotating the valve ball 4, so that the scraper 72 is driven to move along the surface of the flow passage of the valve ball 4.
It should be noted that by providing the annular groove 41, the annular bevel gear 71 can be completely immersed into the flow passage of the valve ball 4, so as to avoid blocking the fluid flowing through the valve ball 4, and at the same time, the annular bevel gear 71 can be closer to the driving bevel gear 8, thereby facilitating the engagement between the annular bevel gear 71 and the driving bevel gear 8.
Preferably, two scrapers 72 are symmetrically arranged inside the annular bevel gear 71.
Preferably, the driving bevel gear 8 is fixedly connected to the bottom cover 6 by bolts.
Further, the bottom of the valve ball 4 is provided with an installation groove 42, the installation groove 42 is formed by stacking a plurality of cylindrical installation cavities, the centers of the cylindrical installation cavities and the axis of the valve rod 5 are located on the same vertical axis, a limiting part 9 is fixedly arranged between the drive bevel gear 8 and the bottom cover 6, the limiting part 9 and the drive bevel gear 8 are both located in the installation groove 42, the limiting part 9 is provided with a cylindrical surface, and the cylindrical surface is tightly attached to the installation groove 42 and can be used for positioning the valve ball 4.
Preferably, the upper end of the valve rod 5 is provided with a handle 51.
