Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a wear-resistant ball valve. Background Art

[0002] A ball valve is a fluid control element that controls the flow of fluid media by rotating the ball. It is widely used in petroleum, chemical, construction, water supply and drainage, thermal power, fire protection, electricity, food and other industries. Its main working principle is to use the rotation of the ball to achieve opening and closing. When the ball rotates to be parallel to the axis of the pipeline, the ball valve is in an open state, and the fluid medium can flow unimpeded; when the ball rotates to be perpendicular to the axis of the pipeline, the ball valve is in a closed state, and the fluid medium is effectively cut off. The ball valve has the advantages of simple structure, small size, light weight, small fluid resistance, fast opening and closing, easy operation, easy installation and maintenance, etc. At the same time, it has good sealing performance and applicability, and can meet the needs of various working conditions.

[0003] The patent document with application number CN202222339076.X discloses a ball valve which is easy to install, which includes a ball valve body and a connector; the connector is fixedly connected to the pipeline in advance, a threaded groove matching the pipeline is opened on the connector, and then after the connection is completed, sealant or sealing tape can be added to the connection between the two as needed, and then the first connecting ring and the second connecting ring of the ball valve body are provided to connect, so that the positioning column passes through the through groove, and in this process, the first connecting ring and the second connecting ring are limited to each other, that is, the conical block is retracted into the limiting groove under pressure, and at the same time, the conical block applies pressure to the positioning spring through the sliding block, and when the positioning column After completely passing through the through groove, the pressure on the tapered block disappears, and then under the action of the positioning spring, the tapered block pops up and resets, thereby completing the limit fixation between the ball valve body and the pipeline. The installation process is quick and can be operated by one person without special tools. Based on the search of the above patents and in combination with the ball valves in the prior art, it is found that in the long-term conveying work of the ball valve, the debris in the conveyed liquid constantly hits the pipeline and the inner wall of the valve body, which will cause wear and damage to the pipeline. Especially when conveying high-pressure and high-flow rate fluids, this wear will be more serious. This is because high pressure and high flow rate will cause the ball valve to withstand greater pressure and impact force, which may cause damage to the seals and structure of the ball valve.

The second buffer bin 602 and the first buffer bin 601 work together to further reduce the pressure and speed of the water flow.

[0032] The filter mechanism 5 includes a docking flange 501, a filter block 502 and a filter mesh slot 503. The docking flange 501 is fixedly installed at the left end of the liquid inlet pipe 4. The filter block 502 is arranged on the inner side of the docking flange 501. The filter mesh slot 503 is opened on the filter block 502. The filter block 502 is threadedly connected to the docking flange 501.

[0033] The filter block 502 is the core part of the filter mechanism 5, which can effectively filter out debris in the water flow. The filter mesh slot 503 is used in conjunction with the filter block 502 to form an efficient filtering system, which can guide the water flow through the filter block 502 and effectively block debris.

[0034] The working principle of the utility model is as follows: the ball valve is additionally provided with a filtering mechanism 5 and a buffer mechanism 6. Before using the wear-resistant ball valve, it is necessary to pre-connect the electric control valve body 1 to electricity and the control terminal, and then connect the valve body to the pipeline system. When using the ball valve, the water flows through the liquid inlet pipe 4 and the valve bin 2, and goes out through the liquid outlet pipe 3. In this process, when the water flows through the filtering mechanism 5, it will be blocked and filtered by the filtering round block 502 and the filtering mesh groove 503, so as to achieve the effect of buffering the water flow and filter out the debris in the water flow. Then the water flow will move into the buffer mechanism 6, and the water flow will first be cut off by the liquid cutting plate 603 to flow upward or downward respectively. A part of the water flow will hit the first buffer plate 604, and be buffered in the first buffer bin 601, and then pass through the first buffer bin 601 is transported to the valve bin 2. At the same time, another part of the water flow will hit the second buffer plate 605 and be buffered in the second buffer bin 602. Then, it is transported to the valve bin 2 through the second buffer bin 602. The water flow intensity is greatly reduced through multiple buffering, and the pressure and speed of the water flow are also greatly reduced. The water flow will no longer damage the valve bin 2, thereby achieving the effect of protecting the valve bin 2. In summary, the filtering mechanism 5 adopts a trough filtering method, which can effectively buffer the water flow intensity and block a certain amount of debris, thereby achieving an efficient filtering effect. The buffer mechanism 6 adopts a fluid guiding structure, which can effectively slow down the water flow intensity and guide the water flow to slowly pass through the inside of the ball valve, thereby achieving the effect of protecting the ball valve and improving the wear resistance of the ball valve.
