Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
[0028] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are merely used to facilitate the description of the present application and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present application.
[0029] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," and the like should be interpreted broadly. For example, these terms may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will readily understand the specific meanings of these terms in this application based on the specific circumstances.
[0030] like Figure 1-6The discharge valve for chemical production shown includes an upper valve body assembly 1 and a lower valve body assembly 2. The upper valve body assembly 1 and the lower valve body assembly 2 are fixedly connected. The upper valve body assembly 1 is also provided with an upper valve body discharge port 103, and the lower valve body assembly 2 is also provided with a lower valve body discharge port 205.
[0031] Combine Figure 2 、 Figure 4 as well as Figure 5 As shown, the upper valve body assembly 1 includes an upper valve body 101 and an upper valve body switch 102. The upper valve body 101 is provided with an upper valve body cone 1011 and a fan-shaped recess 1012. A plurality of positioning ball grooves 1013 are provided on the fan-shaped surface of the fan-shaped recess 1012. The positioning ball grooves 1013 are evenly distributed within a range of 90° with the axis of the switch mounting hole 1015 as the center. A switch mounting hole 1015 is also provided on the upper valve body 101, and the switch mounting hole 1015 is located on the fan-shaped recess 1012.
[0032] The upper valve body switch 102 includes an upper switch plate 1021, and the upper switch plate 1021 is provided with a rotating shaft 1024. The rotating shaft 1024 is fixed with an upper switch handle 1022. A ball spring locating pin 1023 is installed on the switch handle 1022. The ball spring locating pin 1023 abuts against the fan-shaped surface of the fan-shaped recess 1012, and the ball spring locating pin 1023 works in conjunction with the positioning ball groove 1013.
[0033] The rotating shaft 1024 of the upper valve body switch 102 is rotatably connected to the switch mounting hole 1015 on the upper valve body 101. The switch handle 1022 is rotated to make the ball of the ball spring locating pin 1023 roll on the fan-shaped surface of the fan-shaped recess 1012. The ball spring locating pin 1023 moves to the positions of multiple positioning ball grooves 1013 for positioning, which is used to control the opening and closing of the switch plate 1021 of the upper valve body switch 102.
[0034] Combine Figure 2 、 Figure 3 as well as Figure 6As shown, a lower valve body sealing plate 202 is mounted on the lower valve body 201, and a sealing member 203 is fixed to the inner circumference of the lower valve body sealing plate 202. The lower valve body 201 is provided with a gas annular groove 2012 and an air inlet 2011. The air inlet 2011 is radially arranged and communicates with the gas annular groove 2012. The lower valve body 201 is also provided with a plurality of air blowing holes 2013. The air blowing holes 2013 are arranged horizontally and downwardly, with one end communicating with the gas annular groove 2012 and the other end communicating with the lower valve body discharge port 205. The end communicating with the lower valve body discharge port 205 is aligned with the bottom of the lower valve body discharge port. Compressed air entering from the air inlet 2011 can enter the air blowing holes 2013 through the gas annular groove 2012. The compressed air in the air blowing holes 2013 acts on the valve plate of the lower valve body switch 204.
[0035] The lower valve body 201 is mounted with a lower valve body sealing plate 202. The lower valve body 201 is also provided with a lower valve body sealing groove 2014. A sealing strip is installed within the lower valve body sealing groove 2014 to seal the gas ring groove 2012 and prevent compressed air leakage. The upper valve body truncated plate 1011 of the upper valve body 101 extends into the lower valve body discharge port 205 of the lower valve body assembly 2. A sealing member 203 is fixed to the inner circumference of the lower valve body sealing plate 202. The upper valve body truncated plate 1011 abuts against the sealing member 203, sealing the upper valve body truncated plate 1011 and the lower valve body discharge port 205. The upper valve body 101 is also provided with an upper valve body sealing groove 1014, which acts as a seal when the discharge valve is connected to production equipment.
[0036] The lower valve body switch 204 is a butterfly valve switch, and all parts that are in direct contact with the material are made of 304 material, which is corrosion-resistant and durable.
[0037] Combine Figure 1 and Figure 2 As shown, when the production is completed and the material needs to be discharged, the upper valve body switch 102 is first rotated so that the ball spring positioning pin 1023 on the upper valve body switch 102 moves to the positioning ball groove 1013 in the middle position of the fan-shaped recess 1012, and the switch plate 1021 closes the upper valve body discharge port 103, and then the compressed air is turned on. The compressed air enters the gas ring groove 2012 from the air inlet 2011, and enters the blowing hole 2013 from the gas ring groove 2012. The material falling into the lower valve body switch 204 is blown into the storage bin of the next-level equipment through the joint action of multiple blowing holes 2013, and then the lower valve body switch 204 is closed. At this time, the valve plate of the lower valve body switch 204 can be completely closed without blockage or powder leakage.
[0038] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
