Technical Field
[0001] The utility model relates to the technical field of feed valves, in particular to a double-gate air-lock wear-resistant ceramic feed valve. Background Art
[0002] Valves are control components in pipeline fluid delivery systems. They are used to change the pipeline cross-section and the flow direction of the medium. They have functions such as diversion, shutoff, throttling, non-return, diversion or overflow pressure relief. Valves used for fluid control come in a wide variety of varieties and specifications, from the simplest shutoff valves to various valves used in extremely complex automatic control systems. The nominal diameter of the valves ranges from extremely small instrument valves to industrial pipeline valves with a diameter of 10m. They can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids. The working pressure of the valve can range from 0.0013MPa to ultra-high pressure of 1000MPa, and the working temperature can range from ultra-low temperature of c-270°C to high temperature of 1430°C.
[0003] The gate plates of traditional metal gate valves are rectangular or knife-shaped, and the valve seats are made of non-metallic materials such as polytetrafluoroethylene and various rubbers. The actuator pushes the valve stem and the gate plate up and down to realize the opening and closing action of the valve. However, the sealing surface of the metal gate valve is easily subject to collision and wear during use, resulting in poor sealing and leakage. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the sealing surface of the metal gate valve is easily impacted and worn during use, resulting in poor sealing and leakage.
[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: a double-gate air-lock wear-resistant ceramic feed valve, comprising a valve body, a fixing bolt is threadedly connected to the surface of the valve body, a water inlet channel is arranged on one side of the valve body, and a water outlet channel is arranged on the side of the valve body away from the water inlet channel, and a plurality of mounting holes are arranged on the surfaces of the opening ends of the water inlet channel and the water outlet channel, and the plurality of mounting holes are arranged in a circular array, a cavity is arranged inside the valve body, the cavity is through-connected with the water inlet channel and the water outlet channel, and a double-gate valve is installed on the inner wall of the cavity.
[0006] The utility model is further configured as follows: the double gate valve includes a connecting body, a limiting cavity is arranged in the middle of the connecting body, both sides of the limiting cavity penetrate the surface of the connecting body, a spring is slidably connected to the inner wall of the limiting cavity, sliding grooves are arranged at both ends of the connecting body, a sliding rail is slidably connected to the inner side of the sliding groove, and the sliding rail is fixedly connected to the inner wall of the cavity.
[0007] Through the above technical solution, the design of the slide groove and the slide rail enables the connection body to slide flexibly in the cavity, thereby realizing the opening and closing of the double gate valve. The cooperation of the slide groove and the slide rail can also ensure the stability of the connection body during the sliding process, avoiding poor sealing effect caused by shaking.
[0008] The utility model is further configured as follows: sealing doors are provided on both sides of the connecting body, a limiting column is fixedly connected to the middle of the sealing door, the limiting column and the limiting cavity are slidably connected, the limiting column is fixedly connected to both ends of the spring respectively, the bottom end of the sealing door is fixedly connected to a first connecting groove, a second connecting plate is rotatably connected between the first connecting grooves, and the top end of the second connecting plate is fixedly connected to the connecting body.
[0009] Through the above technical solution, the design of the spring enables the limiting column to remain in the middle position of the limiting cavity when no external force is applied, thereby ensuring that the sealing door can fit tightly against the inner wall of the cavity to achieve a good sealing effect. At the same time, the spring can also provide a certain buffer when the sealing door is subjected to external force, thereby preventing the sealing door from being damaged due to excessive impact force.
[0010] The utility model is further configured such that a fixed plate is slidably connected to the top of the connecting body, first connecting plates are rotatably connected to both sides of the fixed plate, a second connecting groove is rotatably connected to the side of the first connecting plate away from the fixed plate, and the second connecting groove is fixedly connected to the top of the sealing door.
[0011] Through the above technical solution, the design of the fixing plate enables the connection body to be fixed in a specific position, thereby maintaining the closed state of the double-gate valve. The rotational connection between the fixing plate and the first connecting plate and the rotational connection between the first connecting plate and the second connecting groove enable the entire double-gate valve to move smoothly during the opening and closing process, avoiding jamming or collision. At the same time, this connection method can also reduce the friction of the double-gate valve during the opening and closing process, thereby extending the service life of the double-gate valve.
[0012] The utility model is further configured as follows: a cylinder is fixedly connected to the middle part of the top end of the fixed plate, the top end of the cylinder is slidably connected to the valve body, the through end of the cylinder is fixedly connected to a push rod, the top end of the push rod is slidably connected to the telescopic end of the hydraulic pump, the bottom end of the hydraulic pump is fixedly connected to a fixing frame, and the bottom end of the fixing frame is fixedly connected to the valve body.

[0015] Through the above technical solution, the design of the sliding column and the sliding cavity can ensure the stability of the cylinder when pushing the fixed plate and the double-gate valve to operate. The sliding of the sliding column in the sliding cavity can effectively reduce the friction between the cylinder and the fixed plate, making the double-gate valve smoother during opening and closing, and improving its service life.
[0016] The utility model is further configured such that an inner liner is installed on the inner wall of the water inlet channel and the water outlet channel, a sealing ring is fixedly connected to one end of the inner liner close to the cavity, the sealing ring is made of rubber material, the sealing ring is inclined, and the sealing ring is slidingly fitted with the sealing door.
[0017] Through the above technical solution, the design of the inner tank and the sealing ring can further improve the sealing performance of the double gate valve. The installation of the inner tank can effectively reduce the scouring and corrosion of the inner wall of the water inlet channel and the water outlet channel by the medium, and extend the service life of the channel. The inclined rubber sealing ring can form a tighter sealing effect when the sealing door fits the inner wall of the cavity, preventing the medium from leaking out from the gap between the sealing door and the inner wall of the cavity.
[0018] The beneficial effects of the utility model are as follows:
[0019] 1. The utility model adopts wear-resistant ceramic material to make the sealing door, which has excellent wear resistance and corrosion resistance, and can effectively resist the wear and erosion of the valve by particles and corrosive substances in the medium. The design of the limit column can ensure the stability of the sealing door during opening and closing, and avoid poor sealing effect due to shaking.
[0020] 2.
