Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a double-ruler ball valve structure. Background Technology

[0002] In the field of industrial fluid transportation, valves are key components for controlling fluid flow. Their performance and reliability directly affect the operating efficiency and safety of the entire system. As the requirements for fluid control in various industries continue to increase, the types and technologies of valves are also constantly developing. Whether it is petrochemical, natural gas transportation, water supply and drainage, or pharmaceutical industries, there is a need for efficient, stable and easy-to-maintain valve products to meet the flow regulation and on / off control needs under different working conditions.

[0003] A dual-ruler ball valve is a specific type of valve designed to allow fluid to pass through a ball with one or more orifices. Rotating the ball controls the alignment of these orifices with the pipeline, thus controlling fluid flow. Dual-ruler ball valves are characterized by their simple structure, ease of operation, good sealing performance, and low maintenance costs. They also offer fast opening and closing speeds, enabling rapid shut-off or opening of fluid passages, which is particularly important in emergency situations. However, traditional ball valve structures struggle to maintain optimal performance over long-term use, leading to surface wear and seat leakage. This not only wastes resources but also poses safety hazards. Therefore, a dual-ruler ball valve structure is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dual-ruler ball valve structure, which aims to improve the problem that the ball valve structure in the prior art is difficult to maintain in optimal condition during long-term use, resulting in wear on the ball valve surface and subsequent valve seat leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-rudder ball valve structure, comprising a housing, a valve mounted on the top of the outer wall of the housing, a knob rotatably connected to the top of the valve, a ball valve component fixedly connected to the bottom end of the knob, a through hole opened on the front side of the outer wall of the ball valve component, fixing rings fixedly connected to the left and right sides of the inner wall of the housing, multiple connecting rods slidably connected to the opposite ends of the two fixing rings, adjacent ends of the multiple connecting rods passing through the outer side of the fixing rings and fixedly connected to a compression ring, springs fixedly connected to the outer walls of the multiple connecting rods, wear-resistant rings fixedly connected to adjacent sides of the two compression rings, rubber rings fixedly connected to the inner walls of the wear-resistant rings, and sealing mechanisms provided on the left and right sides of the housing, the sealing mechanisms being used to provide good sealing performance during installation.

Pressure sensors are installed on the opposite sides of each mounting base. An air pipe is connected to the bottom of each mounting base. Connecting pipes are connected to the left and right ends of the housing. A cavity is formed inside each connecting pipe, and an air ring plate is fixedly connected to the inner wall of the cavity. Multiple expansion rings are connected to the outer wall of the air ring plate, and one end of the air pipe is connected to the outer wall of the air ring plate.

[0008] As a further description of the above technical solution:

[0009] The outer walls of the shell are fixedly connected to the left and right ends of the shell, and the outer walls of the two shells are fixedly connected to the flanges.

[0010] As a further description of the above technical solution:

[0011] Multiple threaded holes are provided on adjacent sides of both flanges, and bolts are threaded onto the inner walls of the multiple threaded holes.

[0012] As a further description of the above technical solution:

[0013] The diameter of the bolt is matched with the inner diameter of the screw hole, and the multiple screw holes are arranged at equal intervals.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the ball valve is rotated, the through hole and the shell are connected to each other, allowing the liquid to flow smoothly. Multiple connecting rods are connected by a fixing ring. The connecting rods allow the extrusion ring to slide left and right. With the help of the spring on the outer wall of the connecting rod, the wear-resistant ring is made to fit against the surface of the ball valve, which can improve the service life of the extrusion ring. At the same time, the rubber ring on the inner wall can effectively seal the outer wall of the ball valve after it is closed, further improving the sealing performance between the ball valve and the shell after the ball valve is closed.

The air inlet is closed by controlling the shut-off valve, and the gas enters the gas ring plate through the gas pipe, causing the expansion ring to expand, thereby completing the multi-segment sealing treatment between the connecting cavity walls. Finally, the flanges are fitted together and reinforced by multiple bolts, which improves the installation efficiency and sealing performance. Attached Figure Description

[0033] Reference Figure 1 , Figure 2 and Figure 4The sealing mechanism 2 includes two mounting seats 201, the bottom ends of which are connected to the top of the outer wall of the housing 1. An air inlet 202 is connected to the front of each mounting seat 201, and the mounting seats 201 and air inlets 202 are interconnected, allowing gas to be injected. A shut-off valve 203 is installed at the top of each mounting seat 201. Pressure sensors 204 are installed on the opposite sides of each mounting seat 201, and these sensors monitor the gas pressure within the internal sealing mechanism in real time.

The multiple screw holes 15 are arranged at equal intervals.

[0034] Specifically, the bottom of each mounting base 201 is connected to the top of the outer wall of the housing 1. Each mounting base 201 has an air inlet 202 on its front side, and the air inlet 202 is interconnected with the mounting base 201, allowing gas to be injected. A shut-off valve 203 is installed at the top of each mounting base 201 to control the gas flow. Pressure sensors 204 are installed on the relatively distant sides of both mounting bases 201 to monitor the gas pressure in the internal sealing mechanism in real time. By precisely controlling the shut-off valve 203, the air inlet 202 can be closed. In operation, the bottom of each mounting base 201 is connected to an air pipe 205, and the left and right ends of the housing 1 are connected to connecting pipes 206.

[0037] Working principle: First, when the ball valve 5 is rotated, the through hole 6 is connected to the housing 1, allowing the liquid to flow smoothly. The fixing ring 7 is fixed on both sides of the inner wall of the housing 1. Multiple connecting rods 8 are connected through the fixing ring 7. One end of the connecting rod 8 is fixed to the compression ring 10. The compression ring 10 can slide left and right through the connecting rod 8. With the help of the spring 9 on the outer wall of the connecting rod 8, the wear-resistant ring 12 is made to fit against the surface of the ball valve 5, which can improve the service life of the compression ring 10. At the same time, the rubber ring 11 on the inner wall can effectively seal the outer wall of the ball valve 5 after it is closed. This design improves the sealing performance between the ball valve 5 and the housing 1 after the ball valve 5 is closed. Gas is injected through the air inlet 202, and the gas pressure of the internal sealing mechanism is monitored in real time by the pressure sensor 204. The air inlet 202 is closed by controlling the shut-off valve 203, and the gas enters the gas ring plate 208 through the air pipe 205, causing the expansion ring 209 to expand, thereby completing the multi-segment sealing treatment between the connecting cavity walls. Finally, the flanges 14 are fitted together and reinforced by multiple bolts 16, which improves the installation efficiency and sealing performance.
