Description

Technical Field

[0001] This utility model relates to the field of valve core technology, specifically a quick-release material valve. Background Technology

[0002] The discharge valve is mainly used to control and regulate the discharge process of powdery and granular materials. It acts like a "switch" for materials and is installed at the bottom of storage equipment such as silos. It can accurately control the speed and flow rate of materials flowing out of the silo.

[0003] There are various structural forms of valve bodies, and one important type is the integrated valve body. The integrated valve body is formed into a whole by casting or forging the various parts of the valve, such as the valve seat and valve cavity. It has relatively high strength and can withstand greater pressure.

[0004] The valve body is usually manufactured as a single piece with the valve cover. However, this process is too complicated when it is necessary to disassemble the internal rotor, which increases the difficulty of operating the rotor and thus increases the disassembly time.

[0005] Therefore, a quick-release material valve is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A quick-release material valve of this utility model includes a valve body with a support rod fixedly connected to its side wall; a cover plate is rotatably connected to the middle of the support rod; multiple bolts are threadedly connected inside the cover plate; multiple threaded grooves are formed on the surface of the valve body; the threaded grooves and bolts are correspondingly arranged and threadedly connected; the ends of the bolts are circular; a rotor is disposed inside the valve body. Separating the cover plate from the valve body increases the flexibility of the cover plate and facilitates the removal of the rotor. When operating the rotor, the bolts are rotated out of the valve body, and then the cover plate is opened to operate the rotor. The bolts allow for quick disassembly of the cover plate, reducing disassembly time and simplifying the disassembly process. The circular end of the bolt increases the holding area during rotation, reducing slippage and increasing the rotation speed of the bolt.

[0008] Preferably, a plurality of telescopic sleeves are fixedly connected to the top of the valve body; the telescopic sleeves and bolts are correspondingly arranged; a compression spring is fixedly connected to the end of the telescopic sleeve; the bottom of the compression spring and the valve body are fixedly connected; by adding telescopic sleeves to hold the bolt in the gap, the impact of vibration generated when the rotor rotates on the bolt can be reduced. When the bolt is subjected to vibration from the rotor, the bolt and the end of the telescopic sleeve come into contact. At this time, the telescopic sleeve will hold the bolt in place, thereby reducing bolt shaking and increasing the stability of the bolt when fixing the cover plate and the valve body.

[0009] Preferably, an elastic cloth is fixed to the end of the telescopic sleeve; the elastic cloth and the telescopic sleeve are correspondingly arranged; by adding the elastic cloth, the resistance during the rotation of the bolt can be reduced, thereby increasing the smoothness of the contact between the telescopic sleeve and the bolt. Before the bolt and the telescopic sleeve contact, the elastic cloth will press down the telescopic sleeve a part in advance to reduce the resistance when the bolt and the telescopic sleeve contact.

[0010] Preferably, a guide plate is fixedly connected to the top of the valve body; the guide plate and the threaded groove are correspondingly arranged; the guide plate and the bolt are in sliding fit; by adding the guide plate to guide the movement of the bolt, the limit can be added when the cover plate and the valve body contact, thereby reducing the misalignment when the cover plate and the valve body are fitted together. When the valve body and the cover plate are fitted together, the guide plate will enter the interior of the cover plate, thereby reducing the gap between the bolt and the cover plate and increasing the accuracy of the bolt entering the threaded groove.

[0011] Preferably, a suction cup is fixed to the outer wall of the guide plate; the suction cup is located in the lower middle part of the guide plate; by adding the suction cup, the cover plate can be adsorbed after it comes into contact with the valve body, so that the cover plate is initially fixed, thereby reducing the shaking when the bolts are not fixed to the cover plate.

[0012] Preferably, a plurality of damping springs are fixedly connected to the middle of the cover plate; a slider is fixedly connected to the end of the damping spring; by increasing the absorption of the impact force of the cover plate falling when the cover plate falls by increasing the slider, the collision between the cover plate and the valve body is reduced, thereby increasing the protection of the cover plate and the valve body.

[0013] The utility model is beneficial in that:

[0014] 1. The quick-release material valve of this utility model increases the flexibility of the cover plate by separating the cover plate and the valve body, and also makes it easier to remove the rotor. When operating the rotor, the bolt is turned out of the valve body and then the cover plate is opened to operate the rotor. The use of bolts allows for quick removal of the cover plate, reducing the time required for removal and simplifying the disassembly process. By setting the bolt end as a ring, the holding area is increased when the bolt is rotated, thus reducing slippage during rotation and increasing the speed of bolt rotation.

[0015] 2. The quick-release material valve of this utility model reduces the impact of rotor vibration on the bolt by adding a telescopic sleeve to hold the bolt in the gap. When the bolt is subjected to rotor vibration, the ring and the end of the telescopic sleeve come into contact. At this time, the telescopic sleeve will hold the ring in place, thereby reducing bolt shaking and increasing the stability of the bolt when fixing the cover plate and valve body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6As shown in the embodiment of this utility model, a quick-release valve includes a valve body 1. A support rod 11 is fixedly connected to the side wall of the valve body 1. A cover plate 12 is rotatably connected to the middle of the support rod 11. Multiple bolts 13 are threadedly connected inside the cover plate 12. Multiple threaded grooves 15 are formed on the surface of the valve body 1. The threaded grooves 15 and bolts 13 are correspondingly arranged and threadedly connected. The ends of the bolts 13 are annular. A rotor 14 is disposed inside the valve body 1. During operation, when it is necessary to remove the rotor 14, the multiple bolts 13 need to be rotated to loosen them until they are disengaged from the threaded grooves 15. At this time, the cover plate 12 can be rotated to open the valve body 1. Then, the rotor 14 can be removed from the inside of the valve body 1 using a tool. When it is necessary to insert the rotor 14, the rotor 14 is first installed into the valve body. The valve body 1 is then closed by rotating the cover plate 12 inside the valve body 1. Multiple bolts 13 are then rotated to insert into the valve body 1, thus securing the valve body 1 and the cover plate 12. Separating the cover plate 12 from the valve body 1 increases the flexibility of the cover plate 12 and facilitates the removal of the rotor 14. When operating the rotor 14, the bolts 13 are rotated out of the valve body 1, and the cover plate 12 is opened to operate the rotor 14. The bolts 13 allow for quick disassembly of the cover plate 12, reducing disassembly time and simplifying the process. The circular end of the bolt 13 increases the holding area during rotation, reducing slippage and increasing the rotation speed of the bolt 13.

[0027] like Figure 3 As shown, multiple telescopic sleeves 2 are fixedly connected to the top of the valve body 1; the telescopic sleeves 2 and bolts 13 are correspondingly arranged; a compression spring 21 is fixedly connected to the end of the telescopic sleeve 2; the bottom of the compression spring 21 and the valve body 1 are fixedly connected; during operation, when the bolt 13 is rotated, the ring at the end of the bolt 13 will contact the top of the telescopic sleeve 2. At this time, the end of the telescopic sleeve 2 will retract to reduce the impact on the rotation of the bolt 13. After the bolt 13 has finished rotating, the ring will be stuck in the gap between the telescopic sleeves 2, thereby limiting the bolt 13. At the same time, the telescopic sleeves 2 can also be retracted. Pressing down prevents the bolt 13 from contacting the other bolt 13 during rotation. After the bolt 13 has finished rotating, the telescopic sleeve 2 is released. At this time, the compression spring 21 will extend the telescopic sleeve 2 to its longest position, which will also limit the bolt 13. By adding the telescopic sleeve 2 to hold the bolt 13 in the gap, the impact of the vibration generated by the rotor 14 during rotation on the bolt 13 can be reduced. When the bolt 13 is subjected to the vibration of the rotor 14, the ring and the end of the telescopic sleeve 2 will contact each other. At this time, the telescopic sleeve 2 will hold the ring, thereby reducing the shaking of the bolt 13 and increasing the stability of the bolt 13 when fixing the cover plate 12 and the valve body 1.

[0028] like Figure 3 As shown, an elastic cloth 3 is fixedly connected to the end of the telescopic sleeve 2; the elastic cloth 3 and the telescopic sleeve 2 are correspondingly arranged; during operation, when the bolt 13 contacts the telescopic sleeve 2, it will squeeze the telescopic sleeve 2 one by one. At this time, when the bolt 13 leaves the previous telescopic sleeve 2 and reaches between the telescopic sleeves 2, the bolt 13 will bend the elastic cloth 3. Since the elastic cloth 3 will generate tension when it bends, the elastic cloth 3 will drive the next telescopic sleeve 2 to move slightly downward, thereby increasing the smoothness of the contact between the bolt 13 and the telescopic sleeve 2 during rotation; by adding the elastic cloth 3, the resistance during the rotation of the bolt 13 can be reduced, thereby increasing the smoothness of the contact between the telescopic sleeve 2 and the bolt 13. Before the bolt 13 and the telescopic sleeve 2 contact, the elastic cloth 3 will press down the telescopic sleeve 2 a part in advance to reduce the resistance when the bolt 13 and the telescopic sleeve 2 contact.

[0029] like Figure 3 As shown, a guide plate 4 is fixedly connected to the top of the valve body 1; the guide plate 4 and the threaded groove 15 are correspondingly arranged; the guide plate 4 and the bolt 13 are in sliding fit; during operation, when the cover plate 12 rotates and contacts the valve body 1, the end of the bolt 13 will first enter the interior of the guide plate 4. After the bolt 13 enters the interior of the guide plate 4, it will move along the guide plate 4 and contact the threaded groove 15. At this time, the bolt 13 is rotated into the threaded groove 15 for fixing. By adding the guide plate 4 to guide the movement of the bolt 13, a limit can be added when the cover plate 12 and the valve body 1 contact, thereby reducing the misalignment when the cover plate 12 and the valve body 1 are fitted together. When the valve body 1 and the cover plate 12 are fitted together, the guide plate 4 will enter the interior of the cover plate 12, thereby reducing the gap between the bolt 13 and the cover plate 12 and increasing the accuracy of the bolt 13 entering the threaded groove 15.

[0030] like Figure 2 As shown, a suction cup 5 is fixed to the outer wall of the guide plate 4; the suction cup 5 is located in the lower middle part of the guide plate 4; during operation, when the valve body 1 and the cover plate 12 come into contact, the guide plate 4 will vent its internal air, thereby forming an air pressure difference with the outside air, and then adsorb the cover plate 12. At this time, when the bolt 13 is rotated, the stability of the cover plate 12 will be increased; by adding the suction cup 5, the cover plate 12 can be adsorbed after it comes into contact with the valve body 1, so that the cover plate 12 is initially fixed, thereby reducing the shaking when the bolt 13 is not fixed to the cover plate 12.

[0031] like Figure 4As shown, a plurality of damping springs 6 are fixedly connected to the middle of the cover plate 12; a slider 61 is fixedly connected to the end of the damping spring 6; during operation, when the cover plate 12 is rotated, the cover plate 12 will move closer to the valve body 1. When the valve body 1 and the cover plate 12 come into contact, an impact will occur. When the cover plate 12 and the valve body 1 collide, a shaking will occur. At this time, the slider 61 will contact the rotor 14 before the cover plate 12, thereby absorbing the impact force when the cover plate 12 falls. Then, the cover plate 12 can be pressed down to make it fall slowly or the cover plate 12 can be left to fall freely and merge with the valve body 1. By increasing the absorption of the impact force of the cover plate 12 falling when the slider 61 falls, the collision between the cover plate 12 and the valve body 1 is weakened, thereby increasing the protection of the cover plate 12 and the valve body 1.

[0032] Working principle: When the rotor 14 needs to be removed, multiple bolts 13 need to be loosened by rotating them until they are disengaged from the threaded groove 15. At this time, the cover plate 12 can be rotated to open the valve body 1. Then, the rotor 14 can be removed from the valve body 1 using a tool. When the rotor 14 needs to be inserted, the rotor 14 is first installed into the valve body 1, and then the cover plate 12 is rotated to close the valve body 1. Then, multiple bolts 13 are rotated to insert the bolts 13 into the valve body 1, thereby fixing the valve body 1 and the cover plate 12. When the bolts 13 are rotated, the rings at the ends of the bolts 13... When the bolt 13 comes into contact with the top of the telescopic sleeve 2, the end of the telescopic sleeve 2 will retract to reduce the impact on the rotation of the bolt 13. After the bolt 13 has finished rotating, the ring will be stuck in the gap between the telescopic sleeves 2, thus limiting the bolt 13. At the same time, the telescopic sleeves 2 can be pressed down uniformly so that the bolt 13 does not come into contact with the telescopic sleeve 2 when it rotates. When the bolt 13 has finished rotating, the telescopic sleeve 2 is released. At this time, the compression spring 21 will extend the telescopic sleeve 2 to its longest state, which will also limit the bolt 13. When the bolt 13 comes into contact with the telescopic sleeve 2, it will squeeze the telescopic sleeve 2 one by one. At this time, the elastic cloth 3 will be on the bolt 1. When bolt 13 leaves the previous telescopic sleeve 2 and reaches the space between the telescopic sleeves 2, it will bend the elastic cloth 3. Because the elastic cloth 3 generates tension when bent, it will cause the next telescopic sleeve 2 to move slightly downwards, thus increasing the smoothness of contact between bolt 13 and the telescopic sleeve 2 during rotation. When cover plate 12 rotates and contacts valve body 1, the end of bolt 13 will first enter the interior of guide plate 4. After entering the interior of guide plate 4, bolt 13 will move along guide plate 4 and contact the threaded groove 15. At this time, bolt 13 will be rotated into the threaded groove 15 for fixing. When valve body 1 and cover plate 12... After contact, the guide plate 4 will expel the air inside itself, thus creating a pressure difference with the outside air, and then it will attract the cover plate 12. At this time, rotating the bolt 13 will increase the stability of the cover plate 12. When the cover plate 12 is rotated, the cover plate 12 will move closer to the valve body 1. When the valve body 1 and the cover plate 12 come into contact, an impact will occur. When the cover plate 12 and the valve body 1 collide, a shaking will occur. At this time, the slider 61 will contact the rotor 14 before the cover plate 12, thereby absorbing the impact force when the cover plate 12 falls. Then, the cover plate 12 can be pressed to make it fall slowly or the cover plate 12 can be left to fall freely and merge with the valve body 1.
