[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2The utility model provides a technical solution: a pressure-resistant sealing valve specially used for a tank body, which has a unique structural design and mainly includes the tank body itself, as well as the upper valve tube, valve body, valve plate, cylinder, magnetic switch, upper inflatable sealing strip groove, lower inflatable sealing strip groove and inflatable sealing strip and other components. The upper valve tube 9 is tightly connected to the tank body to ensure the sealing of the entire system; the valve body is connected to the upper valve tube 9, and is composed of a three-layer structure of an upper template 2, an intermediate gasket 3 and a lower template 4. The intermediate gasket 3 is placed between the upper template 2 and the lower template 4 to form a cavity. This design makes the valve body more stable; the valve plate 6 is arranged in the cavity and can slide horizontally to realize the opening and closing of the valve; the cylinder 1 is installed on the lower side of the plate wall of the lower template 4, and its driving end is connected to the valve plate 6 to provide power for the lateral movement of the valve plate 6. At the same time, circular holes are provided on the plate walls of the upper template 2, the lower template 4 and the valve plate 6 to facilitate the internal Gas flows; the magnetic switch 5 is arranged on the lower side of the lower template 4 and is triggered as the valve plate 6 moves; the upper inflatable sealing strip groove 7 is located on the outer side of the upper valve tube 9, above the cavity, and penetrates the plate wall of the upper template 2; the lower inflatable sealing strip groove 8 is arranged on the lower side of the cavity and penetrates the plate wall of the lower template 4; the inflatable sealing strip is activated by the magnetic switch 5, and there are two of them, which are arranged inside the upper inflatable sealing strip groove 7 and the lower inflatable sealing strip groove 8 respectively. When the circular hole of the valve plate is aligned with the circular holes of the upper and lower templates, the magnetic switch is triggered at the same time, and the inflatable sealing strips installed in the upper inflatable sealing groove and the lower inflatable sealing groove are inflated, and the valve is in the open state. When the valve plate slides to the solid plate and is aligned with the circular holes of the upper and lower templates, the magnetic switch is triggered at the same time, and the inflatable sealing strips in the upper and lower inflatable sealing grooves are inflated, the valve plate is sealed, and the valve is in the closed state. The upper valve tube can be directly welded to the tank body, which can minimize the distance between the valve plate and the inner wall of the tank body, thereby minimizing the thickness of the material block formed by extrusion during the mixing process.

[0023] Specifically, the valve plate 6 is carefully designed in size, and its length and width are significantly larger than the diameter of the upper valve tube 9. This size advantage ensures that the valve plate 6 can fully cover and block the discharge end of the upper valve tube 9. In this way, during operation, it can effectively prevent the material or other media from accidentally leaking from the discharge end, thereby improving the sealing performance of the system. At the same time, this design also ensures that while the valve plate 6 blocks the discharge end of the upper valve tube 9, it will not cause unnecessary waste due to its oversized size, reflecting the economy and practicality of the design.

[0024] Specifically, the upper inflatable sealing strip groove 7 and the lower inflatable sealing strip groove 8 are of the same size and shape, and their positions correspond to each other. Such a design can ensure the sealing performance of the valve.

[0025] Specifically, a lower valve tube 10 is provided on the lower side of the lower inflation sealing strip groove 8, and the valve port of the lower valve tube 10 corresponds to the valve port of the upper valve tube 9. At the same time, the lower valve tube 10 and the upper valve tube 9 are separated by a cavity. Such a structure can effectively prevent leakage of the valve when opening and closing.

[0026] Specifically, the diameters of the upper valve tube 9 and the lower valve tube 10 are exactly the same, which means that the dimensions of the two are consistent, ensuring coordination during operation. At the same time, their longitudinal central axes completely overlap, which means that the center lines of the two are in a straight line. Such a layout is conducive to uniform force on the valve and improves the operating efficiency of the valve. Such a design takes into account the balance and stability of the valve, so that the valve can be opened and closed more smoothly, reducing additional wear and energy consumption caused by imbalance. This design not only improves the service life of the valve, but also improves the operating efficiency and economy of the entire system. Therefore, the design of the upper valve tube 9 and the lower valve tube 10 not only ensures the balance and stability of the valve, but also improves the reliability and economy of the system.

[0027] Specifically, at the connection between the valve and the tank body, high-precision welding technology is used, or the upper valve tube 9 is tightly combined with the tank body through an integrated molding process. This design method not only greatly improves the sealing performance between the valve and the tank body, effectively prevents safety hazards such as medium leakage, but also greatly simplifies the installation and maintenance process. In practical applications, this connection method can save a lot of time and labor costs, and also reduces the risk of equipment damage caused by improper maintenance. In addition, since the welding or integrated molding connection method has high stability and durability, it can significantly improve the operating efficiency and service life of the entire equipment. In general, this design takes into account multiple aspects of installation, maintenance and equipment performance, and embodies a high degree of industrial design and engineering practice wisdom.

[0028] Working principle: When the utility model is working, the upper valve tube is connected to the tank body and directly welded to the tank body, which reduces the distance between the valve plate and the inner wall of the tank body, and effectively prevents the material blocks formed by extrusion during the mixing process. The valve body is composed of an upper template, an intermediate gasket, and a lower template. The intermediate gasket is arranged between the upper template and the lower template to form a cavity. The valve plate slides laterally in the cavity, and is powered by a cylinder. When the valve needs to be opened, the cylinder drives the valve plate to move laterally in the cavity. When the circular hole on the valve plate is aligned with the circular holes of the upper template and the lower template, the magnetic switch is triggered. After the magnetic switch is started, the inflatable sealing strips located in the upper inflatable sealing strip groove and the lower inflatable sealing strip groove begin to inflate. The inflation of the inflatable sealing strip causes the valve to reach an open state, allowing materials to pass through.

[0029] When the valve needs to be closed, the cylinder drives the valve plate to move laterally in the cavity again. When the solid part of the valve plate is aligned with the circular holes of the upper template and the lower template, the magnetic switch is triggered. The triggering of the magnetic switch causes the inflatable sealing strips in the upper inflatable sealing strip groove and the lower inflatable sealing strip groove to be inflated again. The inflation of the inflatable sealing strip forms a seal between the valve plate and the upper template and the lower template, and the valve is in a closed state.

[0030] The setting of the upper and lower inflatable sealing strip grooves and the inflation of the inflatable sealing strips ensure good sealing performance of the valve in the closed state. The design of the valve and the selection of materials ensure its pressure resistance under high-pressure environment. The special pressure-resistant sealing valve for tank body realizes the opening and closing of the valve through its unique mechanical structure and air pressure control system, while ensuring good sealing performance and pressure resistance.
