Description

Technical Field

[0001] This invention relates to the field of unloading valve technology, and in particular to an installation method for unloading valves that facilitates installation and maintenance. Background Technology

[0002] The discharge valve, also known as a discharge device, is a key component of dust removal equipment for ash discharge, air supply, and feeding of other equipment. It is suitable for powdery and granular materials.

[0003] There are many structural forms of unloading valves, among which gate valves are the most commonly used. Their structure mainly consists of valve body, gate, valve stem, and transmission mechanism. The gate and the valve seat in the inner cavity of the valve body cooperate with each other to control the opening or closing of the gate for the material.

[0004] Traditional unloading valves and feeders are fixed with bolts, and the valve body is a single unit. The internal gate is inconvenient to remove after installation. If the unloading valve needs maintenance or the valve plate needs to be replaced, professional personnel are required to disassemble and install it, which increases the difficulty of installation and disassembly.

[0005] Therefore, it is necessary to provide an installation method for the unloading valve that is easy to install and maintain to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides an installation method for a discharge valve that is easy to install and maintain. It solves the problem that if an integral discharge valve is installed on a feeding machine with fixing bolts, professional personnel are required to disassemble and install it later when maintenance or replacement of the valve plate is needed, which increases the difficulty of disassembly and installation.

[0007] To solve the above-mentioned technical problems, the present invention provides an easy-to-install and maintain unloading valve comprising: a valve body;

A sealing plate is fixedly connected to one end of each slide rod. A sealing plug is fixedly connected to the back of the sealing plate. A servo motor is fixedly connected to the front of the sealing plate. A valve stem is fixedly connected to the output end of the servo motor. Multiple valve plates are fixedly connected to the outer surface of the valve stem. A mating block is fixedly connected to one end of the back of the valve stem.

[0009] Two connecting strips are fixedly connected to the front of the valve body near the top and bottom. Each of the two connecting strips is threaded with a first threaded bolt at opposite positions. A rotating port is opened on the back of the inner wall of the valve body, and a bearing is installed inside the rotating port. A feed pipe is fixedly connected to the top of the valve body. Both sides of the feed pipe at the top position are fixedly connected with retaining strips. A connecting pipe is provided at the top of the feed pipe. Both sides of the connecting pipe are fixedly connected with mounting buckles. The bottom of each mounting buckle is threaded with two second threaded bolts.

[0010] The sliding rod passes through the mounting ring, and the mating block is inserted into the inner ring of the bearing. The front of the valve body has an opening for the valve plate to be pulled out. After the valve plate is installed, it is sealed with a sealing plug. The top and bottom of the sealing plate have holes for threaded connection with the first threaded bolts. The first threaded bolts are located at the top and bottom of the two connecting strips, respectively. The two connecting strips are located at the top and bottom of the sealing plate. See reference [link / reference needed] for details. Figure 1 The retaining strip is inserted from the front of the mounting buckle, and two holes are opened at the bottom of the retaining strip for threaded connection with the second threaded bolt.

[0011] Preferably, a connecting frame is fixedly connected to the top of the connecting pipe, and four mounting holes are provided on the top of the connecting frame.

[0012] The mounting holes are located at the four corners of the top of the connecting frame.

[0013] Preferably, a first support spring is fixedly connected to the back of the inner wall of each of the two mounting buckles, and a contact plate is fixedly connected to one end of the front of each of the first support springs.

[0014] The back of the contact plate and the card strip make contact.

[0015] Preferably, the other end of each of the two slide bars is fixedly connected to a limit block, and the bottom of the valve body is fixedly connected to a feed pipe.

[0016] The limit block prevents the slide bar from being fully pulled out.

[0017] Preferably, a mounting base is fixedly connected to the front side of the sealing plate, and a control switch is fixedly connected to the front side of the mounting base.

[0018] The control switch can control the start and stop of the servo motor.

[0019] Preferably, a protective shell is fixedly connected to the front of the sealing plate, and ventilation holes are provided on both sides of the protective shell.

[0020] Preferably, the outer surface of the valve stem is fixedly connected to a plurality of fixing rods, and the front side of the inner wall of each fixing rod is fixedly connected to a mounting plate.

[0021] The front of the fixing rod has a groove that allows the mounting block to be inserted.

[0022] Preferably, a second support spring is fixedly connected to the back of each mounting plate, and a support plate is fixedly connected to the other end of each second support spring.

[0023] The second support spring also provides support to the front of the mounting block.

[0024] Preferably, each of the fixed rods has an installation block inside, and a valve plate is fixedly connected to the other side of each installation block. An installation disc is installed on one end of the back of the valve rod by bolts.

[0025] The mounting plate can seal the groove on the back of the fixing rod, thereby allowing the mounting block to be snapped inside the fixing rod. A mating block is fixedly connected to one end of the back of the mounting plate.

[0026] Preferably, the easy-to-install and maintain unloading valve requires an installation method that includes the following steps;

[0027] S1: First, manually remove the internal retaining strips of the four second threaded bolt mounting buckles. Then, pull the valve body to pull the retaining strips out from inside the mounting buckles, which will separate the feed pipe and the connecting pipe. After removing the valve body, it can be inspected or maintained. After the inspection is completed, simply insert the retaining strips from the front of the mounting buckle, so that the back of the retaining strips contacts the contact plate. Then, compress the first support spring and fix the retaining strips inside the mounting buckle through the second threaded bolts to complete the disassembly and assembly of the valve body.

[0028] S2: If the valve plate needs to be replaced, simply remove the two first threaded bolts after removing the valve body to release the restriction on the sealing plate. Then, pull the sealing plate outward to remove the valve plate from the valve body on the valve stem. During the outward movement of the sealing plate, the slide rod will slide inside the mounting ring. After removing the valve plate, simply remove it from one end of the servo motor output shaft for replacement. Then, reinsert the replaced valve plate into the valve body and seal the front of the valve body with the sealing plug and sealing plate. Finally, secure the sealing plate with the first threaded bolts.

[0029] Simply fix it between the two connecting strips;

[0030] S3: When replacing a single valve plate, first release the restriction on the sealing plate, then pull the valve plate out of the valve body. After the other end of the valve stem is completely pulled out of the valve body, simply use a tool to remove the bolts, and you can remove the mounting plate from the other end of the valve stem. Then, remove the valve plate to be replaced from the fixed rod. The mounting block of the valve plate is stuck inside the fixed rod. When pulling the valve plate, you can remove the mounting block from the fixed rod, and then remove the valve plate to be replaced from the valve stem. Then, simply insert the mounting block at the bottom of the new valve plate into the fixed rod and push it inward to make the mounting block contact the support plate. By compressing the second support spring through the support plate, the valve plate can be installed on the outer surface of the valve stem. Finally, simply use bolts to install the mounting plate on one end of the valve stem to complete the replacement of a single valve plate.

[0031] Compared with related technologies, the installation method for the unloading valve provided by this invention, which facilitates installation and maintenance, has the following advantages:

[0032] This invention provides a discharge valve that is easy to install and maintain. When the discharge valve and valve plate need to be disassembled for inspection and maintenance, first manually remove the internal retaining strips of the four second threaded bolt mounting buckles. Then, pull the valve body to pull the retaining strips out of the mounting buckles, allowing the feed pipe and connecting pipe to separate. The valve body can then be removed for inspection or maintenance. If the valve plate needs to be replaced, simply remove the two first threaded bolts after removing the valve body to release the restriction on the sealing plate. Then, pull the sealing plate outward to remove the valve plate from the valve body. During the outward movement of the sealing plate, the sliding rod will slide inside the mounting ring, which can provide a locking mechanism between the valve plate and the servo motor. The structure provides support and reduces the difficulty of removing the valve plate. After removing the valve plate, it can be simply removed from one end of the servo motor output shaft for replacement. After inspection or maintenance, simply insert the retaining clip into the mounting buckle. After connecting the connecting pipe and the feed pipe, simply fix the retaining clip inside the mounting buckle with the second threaded bolt to complete the installation. This structure allows for quick disassembly and installation of the discharge valve without the need for professional operation when inspection or maintenance is required. Furthermore, when the valve plate needs to be replaced, the sliding rod and mounting ring work together to reduce the difficulty of removing the valve plate from the valve body, thus lowering the difficulty of valve body disassembly and installation.

[0045] The slide bar 19 passes through the mounting ring 2, and the mating block 25 is inserted into the inner ring of the bearing 23. The front of the valve body 1 has an opening for the valve plate 21 to be pulled out. After the valve plate 21 is installed, it is sealed by the sealing plug 27. The top and bottom of the sealing plate 8 have holes for threaded connection with the first threaded bolt 10. The first threaded bolt 10 is located at the top and bottom of the two connecting strips 9, respectively. For details, please refer to [reference needed]. Figure 1 The retaining strip 12 is inserted from the front of the mounting buckle 16. Two holes are opened at the bottom of the retaining strip 12 for threaded connection with the second threaded bolt 13. Both the first threaded bolt 10 and the second threaded bolt 13 can be manually removed. The connecting pipe 11 is connected to the feeding machine.

[0046] The top of the connecting pipe 11 is fixedly connected to a connecting frame 15, and the top of the connecting frame 15 has four mounting holes 14.

[0047] Mounting holes 14 are located at the four corners of the top of the connecting frame 15, and the connecting frame 15 is connected to the pipe of the feeding machine.

[0056] The easy-to-install and maintain unloading valve requires an installation method that includes the following steps;

[0057] S1: First, manually remove the internal retaining strips 12 of the four second threaded bolts 13 and mounting buckles 16. Then, pull the valve body 1 to pull the retaining strips 12 out of the mounting buckles 16. This will separate the feed pipe 17 and the connecting pipe 11. After removing the valve body 1, it can be inspected or maintained. After the inspection is completed, simply insert the retaining strips 12 from the front of the mounting buckles 16, so that the back of the retaining strips 12 contacts the contact plate 30. Then, compress the first support spring 29 and fix the retaining strips 12 inside the mounting buckles 16 through the second threaded bolts 13 to complete the disassembly and assembly of the valve body.

[0058] S2: If valve plate 21 needs to be replaced, simply remove the two first threaded bolts 10 after removing valve body 1 to release the restriction on sealing plate 8. Then, pull sealing plate 8 outward to remove valve plate 21 from valve body 1 on valve stem 28. During the outward movement of sealing plate 8, slide rod 19 will slide inside mounting ring 2. After removing valve plate 21, simply remove it from one end of the output shaft of servo motor 20 for replacement. Then, reinsert the replaced valve plate 21 into valve body 1, and seal the front of valve body 1 with sealing plug 27 and sealing plate 8. Finally, use the first threaded bolts 10 to secure the sealing plate 21.

[0059] 8 can be fixed between the two connecting strips 9;

[0060] S3: When a single valve plate 21 needs to be replaced, first release the restriction on the sealing plate 8, then pull the valve plate 21 out of the valve body 1. After the other end of the valve stem 28 is completely pulled out of the valve body 1, simply use a tool to remove the bolt 32, and the mounting plate 31 can be removed from the other end of the valve stem 28. Then, remove the valve plate 21 to be replaced from the fixing rod 34. The mounting block 33 of the valve plate 21 is stuck inside the fixing rod 34. When pulling the valve plate 21, the mounting block 33 can be removed from the fixing rod 34, and the valve plate 21 to be replaced can be removed from the valve stem 28. Then, simply insert the mounting block 33 at the bottom of the new valve plate 21 into the fixing rod 34 and push it inward to make the mounting block 33 contact the support plate 22. By compressing the second support spring 35 through the support plate 22, the valve plate 21 can be installed on the outer surface of the valve stem 28. Then, simply use the bolt 32 to install the mounting plate 31 on one end of the valve stem 28 to complete the replacement of a single valve plate 21.

[0061] The working principle of the installation method for the unloading valve provided by this invention, which facilitates installation and maintenance, is as follows:

[0062] First, manually remove the internal retaining strips 12 of the four second threaded bolts 13 and mounting clips 16. Then, pull the valve body 1 to pull the retaining strips 12 out of the mounting clips 16, allowing the feed pipe 17 and the connecting pipe 11 to separate. Removing the valve body 1 allows for inspection or maintenance. If the valve plate 21 needs replacement, simply remove the two first threaded bolts 10 after removing the valve body 1 to release the restriction on the sealing plate 8. Then, pull the sealing plate 8 outwards to remove the valve plate 21 from the valve body 1 on the valve stem 28. During the movement, the slide bar 19 will slide inside the mounting ring 2, which can provide some support for the valve plate 21 and the servo motor 20, reducing the difficulty of removing the valve plate 21. After removing the valve plate 21, it can be removed from one end of the output shaft of the servo motor 20 for replacement. After inspection or maintenance, simply insert the clip 12 into the mounting buckle 16. After the connecting pipe 11 and the feed pipe 17 are connected, simply fix the clip 12 inside the mounting buckle 16 with the second threaded bolt 13 to complete the installation.

[0063] Compared with related technologies, the installation method for the unloading valve provided by this invention, which facilitates installation and maintenance, has the following advantages:

[0064] When the unloading valve and valve plate 21 need to be disassembled for maintenance, first manually remove the internal retaining strips 12 of the four second threaded bolts 13 mounting buckles 16. Then pull the valve body 1 to pull the retaining strips 12 out of the mounting buckles 16, which will separate the feed pipe 17 and the connecting pipe 11. The valve body 1 can then be removed for maintenance or repair. If the valve plate 21 needs to be replaced, simply remove the two first threaded bolts 10 after removing the valve body 1 to release the restriction on the sealing plate 8. Then pull the sealing plate 8 outward to remove the valve plate 21 from the valve body 1 on the valve stem 28. During the outward movement of the sealing plate 8, the sliding rod 19 will slide inside the mounting ring 2, which can provide some support for the valve plate 21 and the servo motor 20. The function is to reduce the difficulty of removing the valve plate 21. After removing the valve plate 21, it can be replaced by simply removing it from one end of the output shaft of the servo motor 20. After inspection or maintenance, simply insert the retaining strip 12 into the mounting buckle 16. After connecting the connecting pipe 11 and the feed pipe 17, simply fix the retaining strip 12 into the mounting buckle 16 with the second threaded bolt 13 to complete the installation. With this structure, when the unloading valve needs to be inspected or maintained, it can be quickly disassembled and installed without the need for professional operation. Furthermore, when the valve plate 21 needs to be replaced, the sliding rod 19 and the mounting ring 2 work together to reduce the difficulty of removing the valve plate 21 from the inside of the valve body 1, thus reducing the difficulty of disassembling and installing the valve body 1.

[0073] Compared with related technologies, the installation method for the unloading valve provided by this invention, which facilitates installation and maintenance, has the following advantages:

[0074] When a single valve plate 21 needs to be replaced, first release the restriction on the sealing plate 8, then pull the valve plate 21 out of the valve body 1. After the other end of the valve stem 28 is completely pulled out of the valve body 1, simply use a tool to remove the bolt 32, and the mounting plate 31 can be removed from the other end of the valve stem 28. Then, remove the valve plate 21 to be replaced from the fixing rod 34. The mounting block 33 of the valve plate 21 is stuck inside the fixing rod 34. When pulling the valve plate 21, the mounting block 33 can be removed from the fixing rod 34, and the valve plate 21 to be replaced can be removed from the valve body 1. After removing the valve stem 28, simply insert the mounting block 33 at the bottom of the new valve plate 21 into the inside of the fixing rod 34 and push it inward to make the mounting block 33 contact the support plate 22. The valve plate 21 can be installed on the outer surface of the valve stem 28 by compressing the second support spring 35 through the support plate 22. Then, simply install the mounting plate 31 on one end of the valve stem 28 with the bolt 32 to complete the replacement of a single valve plate 21. With this structure, when a single valve plate 21 is worn and needs to be replaced, it can be quickly replaced. The operation is simple and the cost is reduced.
