Description

Technical Field

[0001] The invention relates to the technical field of discharge valves, and in particular to a plunger-type ultra-high temperature corrosion-resistant discharge valve. Background Art

[0002] The plunger discharge valve is a device used to control the flow of liquid. It discharges substances through the interaction between the piston and the channel inside the valve. It mainly adopts manual, pneumatic, hydraulic and electric drive modes.

[0003] The closing of the plunger valve is generally composed of a plunger, two upper and lower elastic sealing rings and a metal partition frame. The sealing effect is achieved by the close cooperation between the plunger and the sealing rings. The plunger is inserted in the two sealing rings. When the plunger valve is opened and closed, the plunger moves slowly in the sealing rings, and the contact surface is almost not worn. When closing, the plunger is inserted into the lower sealing ring to cut off the flow channel. When opening, although the plunger is separated from the lower sealing ring, it is still hidden in the upper sealing ring, keeping it isolated from the outside world to prevent leakage.

[0004] However, most of the current plunger discharge valves are difficult to meet the special requirements of resistance to ultra-high temperatures and strong corrosion. Since the discharge valves made of ordinary metal materials will undergo chemical reactions after contacting with high-temperature and highly corrosive fluid materials, corroding the valve body, valve core, and valve stem to pollute the materials, the existing plunger valves used in high-temperature and highly corrosive environments are generally made of special materials. However, during the use of the plunger valve, the valve stem will be affected by the high temperature and will bend and deform, which will cause the plunger to get stuck in the valve body, affecting the normal operation of the plunger valve. At the same time, it will also increase the risk of material leakage due to poor sealing between the valve body and the plunger. Summary of the invention

[0005] The present invention proposes a plunger-type ultra-high temperature corrosion-resistant discharge valve, which solves the problem in the prior art that the high temperature and strong corrosion environment affects the plunger rod, which easily leads to deformation of the plunger rod, thereby causing the plunger to get stuck and affecting the sealing between the plunger and the valve body.

[0060] The working principle and beneficial effects of the present invention are:

[0061] 1. In the present invention, since the valve body is configured as a structure formed by splicing a left valve body and a right valve body, the processing difficulty is reduced. By providing an annular groove at the splicing portion and adding sealing rings in the two annular grooves, leakage of materials during the process of passing through the feeding pipe into the material discharge assembly can be avoided.

[0062] 2. In the present invention, the plunger body and the plunger cap are made of inorganic non-metallic materials, which will not affect the sealing due to the high temperature and corrosiveness of the material. In the entire movement process, no material will contact the upper plunger rod, which avoids corrosion of the upper plunger rod and increases the service life of the upper plunger rod. At the same time, due to the conical structure on the top of the plunger cap, the plunger cap can easily pass through the discharge port of the reactor without getting stuck and affecting its sealing performance.

[0063] 3. In the present invention, since the upper plunger rod goes deep into the sliding cavity, the upper plunger rod is bent by heat. At this time, the universal joint can prevent the plunger body from being stuck in the sliding cavity due to the bending of the upper plunger rod.

[0064] 4. In the present invention, the upper and lower ends of the plug-in block are respectively abutted against the corresponding plug-in blocks. When the upper plunger rod is bent by heat, the elastic block can be set to deform before the universal joint is automatically adjusted, thereby further reducing the impact of high temperature on the upper plunger rod and the lower plunger rod, making its operation more stable and smooth, and further reducing the possibility of the plunger body getting stuck.

[0065] 5. In the present invention, the possibility of material leakage is reduced by setting the sealing component. The material discharge component can prevent the material from solidifying due to cooling during the material discharge process, thereby improving the smoothness of the material discharge. The cooperation between the plunger sleeve and the plunger rod assembly can not only maintain reliable operation in a high-temperature and highly corrosive environment, but also reduce the occurrence of the plunger sleeve being stuck.

DETAILED DESCRIPTION

[0079] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0080] like Figures 1 to 11 As shown, this embodiment proposes a plunger-type ultra-high temperature corrosion-resistant discharge valve, including a valve body, which is installed at the discharge port at the bottom of the reactor 1, and also includes a sealing assembly, a material discharge assembly, a sliding chamber 4, a plunger sleeve and a plunger rod assembly, wherein the valve body is composed of a left valve body 2 and a right valve body 3, and the sealing assembly is installed between the left valve body 2 and the right valve body 3 for sealing. The sealing assembly includes a feeding pipe 5, an annular groove 6 and a sealing ring 7. The left valve body 2 and the right valve body 3 are both obliquely provided with a feeding pipe 5, and the two feeding pipes 5 are butt-jointed. An annular groove 6 is provided at the position where the left valve body 2 and the right valve body 3 are butt-jointed. The feeding pipe 5 is located inside the annular groove 6, and the two annular grooves 6 are fixedly installed with sealing rings 7.

[0081] Specifically, after the reaction of the material in the reactor 1 is completed, the material needs to be discharged. At this time, the plunger rod group is set to push the plunger sleeve to move. At this time, the material in the reactor 1 will enter the feeding channel through the sliding cavity 4, and finally enter the material discharge assembly in the right valve body 3, and the reacted material can be discharged. Since the valve body is set as a structure spliced ​​by the left valve body 2 and the right valve body 3, the processing difficulty is reduced. By opening an annular groove 6 at the splicing point and adding sealing rings 7 in the two annular grooves 6, leakage of the material in the process of passing through the feeding pipe 5 into the material discharge assembly can be avoided.

[0082] It should be added that the left valve body 2 and the right valve body 3 are made of inorganic non-metallic materials, which are resistant to high temperature and corrosion, and have good thermal insulation properties to prevent the material from solidifying when passing through the sliding cavity 4, the feeding pipe 5 and the discharge cavity 9.

[0083] like Figure 3 As shown, the material discharge component is installed inside the right valve body 3 for discharging materials. The material discharge component includes a pipe heater 8, a discharge cavity 9 and a discharge pipe 10. A discharge cavity 9 is opened inside the right valve body 3, and the discharge cavity 9 is connected with the feeding pipe 5. The discharge pipe 10 is fixedly installed at the discharge port of the right valve body 3, and the discharge pipe 10 is connected with the discharge cavity 9, wherein the pipe heater 8 is fixedly installed on the discharge pipe 10.

[0084] Specifically, when the material enters the discharge chamber 9 through the feeding pipe 5, the material entering the discharge chamber 9 will be discharged through the discharge pipe 10, thereby storing the material. When the material passes through the discharge pipe 10, the pipe heater 8 is turned on to heat the material passing through the discharge pipe 10, thereby avoiding the occurrence of material solidification.

[0085] like Figure 5 As shown, a sliding cavity 4 is opened inside the left valve body 2, and a plunger sleeve is installed in the sliding cavity 4 for controlling the discharge. The plunger sleeve includes a plunger body 11, a plunger cap 12 and a plug-in portion. The plunger body 11 is slidably and sealingly installed in the sliding cavity 4, and the plunger cap 12 is fixedly installed on the top of the plunger body 11. The top of the plunger cap 12 is set in a cone shape, wherein the plunger body 11 and the plunger cap 12 are made of inorganic non-metallic materials, and the plug-in portion is installed at the bottom of the plunger body 11 for connecting the plunger rod group.

[0086] Specifically, during the discharge process, the plug-in portion drives the plunger body 11 to slide in the sliding chamber 4, thereby driving the plunger cap 12 to slide, thereby realizing the discharge of the material. The plunger body 11 and the plunger cap 12 are made of inorganic non-metallic materials, which will not be affected by the high temperature and corrosiveness of the material. The plunger body 11 has a relatively long structure, and during the entire movement process, no material will contact the upper plunger rod 15, thereby avoiding corrosion of the upper plunger rod 15 and increasing the service life of the upper plunger rod 15. At the same time, due to the conical structure at the top of the plunger cap 12, the plunger cap 12 can easily pass through the discharge port of the reactor 1 without getting stuck and affecting its sealing performance.

[0087] The above, such as Figure 5 As shown, the plug-in portion includes a connecting block 13 and a plug-in slot 14 . The connecting block 13 is fixedly mounted on the bottom of the plunger body 11 , and a plug-in slot 14 is provided at the bottom of the connecting block 13 .

[0088] Specifically, when the plunger body 11 is driven to move, the plunger body 11 is driven to move through the effect of the plug-in slot 14 , that is, through the connecting block 13 .

[0089] like Figures 7 to 10 As shown, the plunger rod group is installed inside the left valve body 2 and is used to control the action of the plunger set. The plunger rod group includes an upper plunger rod 15, a socket frame 16, a lower plunger rod 17, a universal joint 18, a driving part and a connecting part. The upper plunger rod 15 is arranged at the lower part of the connecting block 13. There is a certain gap between the upper plunger rod 15 and the left valve body 2. The socket frame 16 is fixedly installed on the top of the upper plunger rod 15. The socket frame 16 and the socket slot 14 are slidably matched. The lower plunger rod 17 is arranged at the lower part of the connecting block 13. The universal joint 18 is fixedly installed between the lower plunger rod 17 and the upper plunger rod 15. The upper plunger rod 15 and the lower plunger rod 17 are both made of stainless steel. The driving part is installed at the bottom of the left valve body 2 to drive the lower plunger rod 17 to rotate. The connecting part is installed at the bottom of the lower plunger rod 17 to connect the driving part.

[0090] Specifically, through the arrangement of the plug-in frame 16, when the starting drive portion drives the lower plunger rod 17 to move upward, the lower plunger rod 17 rotates, and the lower plunger rod 17 drives the upper plunger rod 15 to rotate through the universal joint 18, and the upper plunger rod 15 drives the plug-in frame 16 to rotate, and the plug-in frame 16 rotates in the plug-in slot 14, thereby driving the connecting block 13 to move. Since the upper plunger rod 15 is never in contact with corrosive materials, the upper plunger rod 15 will not corrode. However, since the upper plunger rod 15 penetrates deep into the sliding cavity 4, the upper plunger rod 15 is bent by heat. At this time, through the action of the universal joint 18, the phenomenon of the plunger body 11 being stuck in the sliding cavity 4 due to the bending of the upper plunger rod 15 can be avoided.

[0091] The above, such as Figure 7 As shown, the driving part includes a housing 19, a mounting frame 20, an adjusting screw 21, a threaded block 22, a positioning frame 23 and a handwheel 24. The housing 19 is fixedly mounted on the bottom of the left valve body 2, the mounting frame 20 is detachably mounted on the bottom of the housing 19, the adjusting screw 21 is arranged at the bottom of the lower plunger rod 17, the threaded block 22 is threadedly sleeved on the adjusting screw 21, the threaded block 22 is fixedly connected to the mounting frame 20, the positioning frame 23 is fixedly mounted on the bottom of the adjusting screw 21, and the handwheel 24 is fixedly mounted on the positioning frame 23.

[0092] Specifically, when pushing the plunger body 11 to move, first hold the hand wheel 24 and turn the hand wheel 24, thereby driving the positioning frame 23 to rotate, and the positioning frame 23 drives the adjusting screw 21 to rotate, so that under the action of the threaded block 22, the adjusting screw 21 moves along the axial direction of the adjusting screw 21, thereby driving the lower plunger rod 17 to move.

[0093] The above, such as Figures 8 to 10 As shown, the connecting part includes a positioning groove 25, a connecting groove 26, a positioning cylinder 27, a plug-in block 28 and an elastic block 29. A positioning groove 25 is provided at the bottom of the lower plunger rod 17. Two connecting grooves 26 are symmetrically provided inside the positioning groove 25. The positioning cylinder 27 is fixedly installed on the top of the adjusting screw 21. The positioning cylinder 27 is adapted to the positioning groove 25. The plug-in blocks 28 are symmetrically and slidably installed on the positioning cylinder 27. The plug-in blocks 28 are adapted to the connecting groove 26. Elastic blocks 29 are fixedly installed on the upper and lower sides of the two connecting grooves 26. The elastic blocks 29 abut against the plug-in blocks 28. It also includes an elliptical wheel 30, a slide groove 31, a slider 32 and an adjusting rod 33. The elliptical wheel 30 is rotatably installed inside the positioning cylinder 27. The upper and lower ends of the elliptical wheel 30 are provided with slide grooves 31. Two sliders 32 are symmetrically and fixedly installed on the two plug-in blocks 28. The sliders 32 are slidably connected to the slide grooves 31. The adjusting rod 33 is fixedly installed at the bottom of the elliptical wheel 30.

[0094] Specifically, when the adjusting screw 21 is installed at the bottom end of the lower plunger rod 17, the positioning cylinder 27 is inserted into the positioning groove 25. At this time, the plug-in block 28 corresponds to the position of the connecting groove 26. At this time, the adjusting rod 33 is turned, and the adjusting rod 33 drives the elliptical wheel 30 to rotate. The elliptical wheel 30 pushes the slider 32 to move through the slide groove 31, so that the plug-in block 28 is moved out of the positioning cylinder 27 through the setting of the slider 32, so that the plug-in block 28 enters the connecting groove 26, thereby fixing the relative position of the lower plunger rod 17 and the adjusting screw 21. At this time, the upper and lower ends of the plug-in block 28 are respectively abutted against the corresponding plug-in blocks 28. When the upper plunger rod 15 is heated and bent, it can be deformed before the universal joint 18 is automatically adjusted through the setting of the elastic block 29, thereby further reducing the influence of high temperature on the upper plunger rod 15 and the lower plunger rod 17, making its operation more stable and smooth.

[0095] The above, such as Fig.11 As shown, it includes a positioning component, which is installed on the positioning frame 23 and is used to adjust the position of the adjustment rod 33. It includes an adjustment frame 34, a spring 35 and a fixing groove 36. The adjustment frame 34 is slidably installed at the bottom of the adjustment rod 33. The inner bottom wall of the adjustment frame 34 and the top of the adjustment rod 33 are fixedly installed with a spring 35. The bottom of the adjustment frame 34 is circularly provided with four fixing grooves 36 at equal angles. Every two opposite fixing grooves 36 are symmetrically arranged, and the fixing grooves 36 are adapted to the adjustment frame 34.

[0096] Specifically, when adjusting the position of the adjustment rod 33, the adjustment frame 34 is first pulled, and the adjustment frame 34 slides on the adjustment rod 33. At this time, the spring 35 is stretched, and the adjustment frame 34 is disengaged from the fixing groove 36. When the plug-in block 28 enters the connecting groove 26, the adjustment frame 34 corresponds to the position of the other two fixing grooves 36. At this time, the adjustment frame 34 is released, and the adjustment frame 34 is moved into the fixing groove 36 under the action of the spring 35, thereby fixing the position of the adjustment rod 33.

[0097] In summary, after the reaction of the materials in the reactor 1 is completed, the materials need to be discharged. At this time, the adjusting screw 21 is first connected to the lower plunger rod 17. When the adjusting screw 21 is installed at the bottom end of the lower plunger rod 17, the positioning cylinder 27 is inserted into the positioning groove 25. At this time, the plug-in block 28 corresponds to the position of the connecting groove 26. Then the adjusting frame 34 is pulled, and the adjusting frame 34 slides on the adjusting rod 33. At this time, the spring 35 is stretched, and the adjusting frame 34 is disengaged from the fixing groove 36. The elliptical wheel 30 can be driven to rotate through the adjusting rod 33, and the elliptical wheel 30 can be driven to rotate. The slide block 32 is pushed to move through the slide groove 31, so that the plug-in block 28 is moved out of the positioning cylinder 27 through the setting of the slide block 32, so that the plug-in block 28 enters the connecting groove 26, thereby fixing the relative position of the lower plunger rod 17 and the adjusting screw 21. At this time, the upper and lower ends of the plug-in block 28 are respectively abutted against the corresponding plug-in blocks 28, and the adjusting frame 34 corresponds to the position of the other two fixing grooves 36. At this time, the adjusting frame 34 is released, and the adjusting frame 34 is moved into the fixing groove 36 under the action of the spring 35, thereby fixing the position of the adjusting rod 33, and the material can be discharged.

[0098] First, hold the hand wheel 24 and rotate the hand wheel 24 to drive the positioning frame 23 to rotate, and the positioning frame 23 drives the adjusting screw 21 to rotate, so that under the action of the threaded block 22, the adjusting screw 21 moves along the axial direction of the adjusting screw 21, thereby driving the lower plunger rod 17 to move.

[0099] At this time, the lower plunger rod 17 drives the upper plunger rod 15 to rotate through the universal joint 18, and the upper plunger rod 15 drives the plug-in frame 16 to rotate, and the plug-in frame 16 rotates in the plug-in slot 14, thereby driving the connecting block 13 to move. Since the upper plunger rod 15 is never in contact with corrosive materials, the upper plunger rod 15 will not be corroded. However, since the upper plunger rod 15 is deeply inserted into the sliding cavity 4, the upper plunger rod 15 is bent due to heat. At this time, the universal joint 18 can be used to avoid the plunger body 11 being stuck in the sliding cavity 4 due to the bending of the upper plunger rod 15. At the same time, through the setting of the elastic block 29, it can be deformed before the universal joint 18 is automatically adjusted, thereby further reducing the influence of high temperature on the upper plunger rod 15 and the lower plunger rod 17, making its operation more stable and smooth.

[0100] During the discharge process, the plunger body 11 slides in the sliding cavity 4, thereby driving the plunger cap 12 to slide, thereby realizing the discharge of the material, and the materials of the plunger body 11 and the plunger cap 12 are both inorganic non-metallic materials, which will not be affected by the high temperature and corrosiveness of the material. The plunger body 11 has a long structure, and during the entire movement process, no material will contact the upper plunger rod 15, thereby avoiding corrosion of the upper plunger rod 15 and increasing the service life of the upper plunger rod 15. At the same time, due to the conical structure at the top of the plunger cap 12, the plunger cap 12 can easily pass through the discharge port of the reactor 1 without getting stuck and affecting its sealing performance.

[0101] At this time, the material in the reactor 1 will enter the feeding channel through the sliding cavity 4, and finally enter the discharge cavity 9 in the right valve body 3. The material entering the discharge cavity 9 will be discharged through the discharge pipe 10, so that the material is stored. When the material passes through the discharge pipe 10, the pipeline heater 8 is turned on to heat the material passing through the discharge pipe 10, so as to avoid the material solidification. By adding sealing rings 7 in the two annular grooves 6, the leakage problem in the process of the material passing through the feeding pipe 5 into the material discharge assembly can be avoided.

[0102] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
