Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a high-temperature wear-resistant ball valve. Background Technology

[0002] A ball valve is a valve in which the ball, the opening and closing element, 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. In my country, ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceutical industry, water conservancy, power, municipal engineering, and steel, and occupy a pivotal position in the national economy.

[0003] Although some existing high-temperature wear-resistant ball valves are equipped with a filter structure, it is not convenient to automatically clean the filter structure during the fluid filtration process, and the filter structure is prone to clogging after long-term use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a high-temperature wear-resistant ball valve. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature wear-resistant ball valve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature wear-resistant ball valve, comprising a valve body, a wear-resistant sleeve, and a filter assembly. A base is installed below the valve body, and wear-resistant sleeves are protruding and fixed at the four outer corners of the valve body. The inner and outer sides of the valve body are coated with a high-temperature wear-resistant and anti-corrosion coating, and valve pipes are fixed on both sides of the valve body. A filter assembly is installed inside the valve pipe, and the filter assembly includes a filter screen, a connecting frame, a movable shaft, a rotating blade, and an anti-clogging scraper. A connecting frame is fixed to one side of the filter screen, and the connecting frame is bolted to the valve pipe. A movable shaft is rotatably arranged in the middle of the connecting frame, and a rotating blade is fixed to the outside of the movable shaft. An anti-clogging scraper is connected to one side of the upper and lower ends of the connecting frame, and the anti-clogging scraper has an arc-shaped structure.

[0007] Furthermore, a connector is provided above the valve body, and a handle is provided above the connector.

[0008] Furthermore, a connecting flange is installed on one side of the valve pipe, and wear-resistant protrusions are fixed around the outer perimeter of the connecting flange.

[0009] Furthermore, an external flange is installed on one side of the connecting flange, and a lip seal is provided between the connecting flange and the external flange.

[0010] Furthermore, a connecting assembly is installed on the outside of the connecting flange and the external flange, and the connecting assembly includes a positioning sleeve. The positioning sleeve is fixed at the four outer corners of the connecting flange and the external flange, and the positions of the positioning sleeve and the wear-resistant sleeve correspond one-to-one.

[0011] Furthermore, the connecting assembly also includes a positioning rod and a nut, with the positioning rod located inside the positioning sleeve and a nut installed on one side of the positioning rod.

[0012] Furthermore, the outer side of the anti-clogging scraper is in contact with the inner side of the filter screen, and the filter screen has a semi-circular structure.

[0013] This utility model provides a high-temperature wear-resistant ball valve, which has the following beneficial effects:

[0014] This utility model is equipped with a filter assembly, which facilitates the filtration of fluid flowing through the valve pipe and valve body. The semi-circular structure of the filter screen makes it easier to expand the filtration surface compared to a planar structure. During the water flow, it impacts the rotating blade and the movable shaft, which in turn enables the movable shaft to drive the rotation of the anti-clogging scraper. This allows the anti-clogging scraper to clean the inner side of the filter screen without the need for an additional drive structure, making it more convenient to use.

[0015] This utility model is equipped with a valve body, both of which are made of tungsten carbide material. It can maintain its hardness and strength at high temperatures and performs well in terms of wear resistance, corrosion resistance, high temperature resistance and hardness. The high temperature wear-resistant and anti-corrosion coating on the inner and outer sides of the valve body can enhance the high temperature wear resistance of the valve body. The wear-resistant protrusion can also provide wear-resistant protection for the exterior of the valve body. The connecting component facilitates the fastening connection between the external flange and the connecting flange. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-2 As shown, a high-temperature wear-resistant ball valve includes a valve body 1, a wear-resistant sleeve 3, and a filter assembly 11. A base 2 is installed below the valve body 1, and wear-resistant sleeves 3 are fixedly protruding at the four corners of the valve body 1. The inner and outer sides of the valve body 1 are coated with a high-temperature wear-resistant and anti-corrosion coating 12, and valve pipes 6 are fixed on both sides of the valve body 1. A connector 4 is provided on the top of the valve body 1, and a handle 5 is provided on the top of the connector 4. The valve body 1 and the base 2 are both made of tungsten carbide, which can maintain its hardness and strength at high temperatures and performs well in terms of wear resistance, corrosion resistance, high temperature resistance, and hardness. The high-temperature wear-resistant and anti-corrosion coating 12 on the inner and outer sides of the valve body 1 can enhance the high-temperature wear resistance of the valve body 1. The wear-resistant convex plate 8 on the outside of the valve body 1 has a protruding structure, and the hollow groove of the positioning rod 1002 is corresponding inside the wear-resistant sleeve 3, so that it can provide wear-resistant protection for the outside of the valve body 1 while being used with the connecting assembly 10.

[0023] like Figures 3-4As shown, a filter assembly 11 is installed inside the valve pipe 6. The filter assembly 11 includes a filter screen 1101, a connecting frame 1102, a movable shaft 1103, a rotating blade 1104, and an anti-clogging scraper 1105. The connecting frame 1102 is fixed to one side of the filter screen 1101, and the connecting frame 1102 is bolted to the valve pipe 6. The movable shaft 1103 is rotatably mounted in the middle of the connecting frame 1102, and the rotating blade 1104 is fixed to the outside of the movable shaft 1103. An anti-clogging scraper 1105 is connected to one side of the upper and lower ends of the connecting frame 1102, and the anti-clogging scraper 1105 has an arc-shaped structure to prevent clogging. The outer side of the anti-clogging scraper 1105 is in contact with the inner side of the filter screen 1101, and the filter screen 1101 has a semi-circular structure. The filter assembly 11 facilitates the filtration of fluid flowing through the valve pipe 6 and the valve body 1. The semi-circular structure of the filter screen 1101 makes it easier to expand the filtration surface compared to a planar structure. During the water flow, it will impact the rotating blade 1104 and the movable shaft 1103, which will enable the movable shaft 1103 to drive the anti-clogging scraper 1105 to rotate, so that the anti-clogging scraper 1105 can clean the inner side of the filter screen 1101 without adding a drive structure, making it more convenient to use.

[0024] like Figures 1-3 As shown, a connecting flange 7 is installed on one side of the valve pipe 6, and wear-resistant protruding plates 8 are fixed around the outer perimeter of the connecting flange 7. An external flange 9 is installed on one side of the connecting flange 7, and a lip seal is provided between the connecting flange 7 and the external flange 9. A connecting assembly 10 is installed on the outside of the connecting flange 7 and the external flange 9, and the connecting assembly 10 includes positioning sleeves 1001, which are fixed at the four outer corners of the connecting flange 7 and the external flange 9, and the positions of the positioning sleeves 1001 and the wear-resistant sleeves 3 correspond one-to-one. The connecting assembly 10 also includes positioning... The positioning sleeve 1001 has a positioning rod 1002 and a nut 1003 installed on one side of the positioning rod 1002. The external flange 9 is used to fix the external pipeline. The mating between the external flange 9 and the connecting flange 7 facilitates the connection between the external pipeline and the valve pipe 6. In addition to locking the two external flanges 9 and the connecting flange 7 with bolts, the positioning rod 1002 can also connect the positioning sleeve 1001 and the wear-resistant sleeve 3 and be locked with the nut 1003, so that the external flange 9 and the connecting flange 7 are connected and secured.

[0025] In summary, as Figures 1-4As shown, this high-temperature wear-resistant ball valve first fixes the external pipeline to the external flange 9. Then, the external pipeline is connected to the valve pipe 6 by mating the external flange 9 with the connecting flange 7. At this time, in addition to locking the two external flanges 9 and the connecting flange 7 with bolts, the positioning rod 1002 can be connected to the positioning sleeve 1001 and the wear-resistant sleeve 3, and locked with the nut 1003, thereby making the external flange 9 and the connecting flange 7 firmly connected. In use, the valve body 1 and the base 2 are both made of tungsten carbide, which can maintain its hardness and strength at high temperatures. It performs well in terms of wear resistance, corrosion resistance, high temperature resistance and hardness. The valve body 1 has high-temperature wear-resistant and corrosion-resistant coatings on both the inner and outer sides. The coating 12 enhances the high-temperature wear resistance of the valve body 1. The wear-resistant convex plate 8 on the outside of the valve body 1 has a protruding structure, which can provide wear protection for the outside of the valve body 1 while being used in conjunction with the connecting component 10. During use, the filter screen 1101 can filter the fluid flowing through the valve pipe 6 and the valve body 1. During the water flow, it will impact the rotating blade 1104 and the movable shaft 1103, which will cause the movable shaft 1103 to drive the rotation of the anti-clogging scraper 1105. This allows the anti-clogging scraper 1105 to clean the inner side of the filter screen 1101 without adding a drive structure. This completes the use process of the high-temperature wear-resistant ball valve.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
