Description

Technical Field

[0001] This utility model belongs to the field of gate valve technology, specifically an anti-clogging gate valve. Background Technology

[0002] Gate valves are a common type of shut-off valve, primarily controlling the flow of fluid by the vertical movement of a gate. Their core feature is the use of a flat plate perpendicular to the fluid direction to insert into or detach from the flow path, achieving opening and closing with minimal alteration to the fluid's direction and pressure.

[0003] When the existing gate valve is not in use and is about to be closed, the end of the middle gate will push the material at the valve plate through hole to the end, causing material to accumulate at the end. As a result, the gate cannot be completely closed and will always be in a state of leakage. This not only wastes raw materials, but also easily causes problems with the gate valve, leading to repair and replacement. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an anti-clogging gate valve, which has the advantages of preventing blockages and regulating the discharge speed. This invention solves the problem of easy blockage during material discharge, reduces the hassle of subsequent cleaning, improves the performance of the gate valve, and adds the function of freely adjusting the discharge speed, thereby increasing the practicality of the gate valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging gate valve, comprising a hopper body, a fixed seat fixedly disposed on the inner bottom side of the hopper body, a rotating ring slidably disposed on the top surface of the fixed seat, a plurality of elongated grooves being formed on the top surface of the rotating ring, a connecting shaft being movably disposed inside each elongated groove, a valve being fixedly disposed on the bottom surface of the connecting shaft, and the valve being fitted against the fixed seat, a discharge hole being formed in the middle of the fixed seat, and the valve being located outside the discharge hole.

[0006] Preferably, the top inner side of the fixed base is provided with a discharge hole, and the sliding block slides inside the sliding groove.

[0007] Preferably, limit strips are fixedly provided on both sides of the sliding block, and the limit strips slide inside the sliding groove on both sides.

[0008] Preferably, a fixing ring is fixedly provided at the bottom of the fixing base, and multiple screw holes are provided on the outer side of the fixing ring.

[0009] Preferably, a connecting sleeve is fixedly provided at the bottom of the rotating ring, and the connecting sleeve is rotatably connected to the fixed base.

[0010] Preferably, a pusher position is fixedly provided on the outer side of the rotating ring, and multiple reinforcing ribs are fixedly provided on the outer side of the pusher position.

[0011] Preferably, a base is fixedly provided on the bottom surface of the hopper body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention involves the operator rotating a pusher, which in turn drives a rotating ring. The rotating ring drives a long groove, which in turn drives a connecting shaft inside the groove. The connecting shaft then causes the valve to move linearly along the sliding groove. The limiting strips on both sides of the sliding block slide inside the fixed seat, thus limiting its movement. As the valve moves, it gradually opens the discharge port, allowing material to be discharged. The operator can also freely adjust the discharge speed as needed. Furthermore, since the discharge port is located at the center of the circle, there is no need to worry about material blockage. Attached Figure Description

[0023] 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 protection scope of the present utility model.

[0024] likeFigures 1 to 6 As shown, this utility model provides an anti-clogging gate valve, including a hopper body 1. A fixed seat 2 is fixedly installed on the inner bottom of the hopper body 1. A rotating ring 3 is slidably installed on the top surface of the fixed seat 2. Multiple long grooves 4 are opened on the top surface of the rotating ring 3. A connecting shaft 5 is movably installed inside each long groove 4. A valve 6 is fixedly installed on the bottom surface of the connecting shaft 5 and is in contact with the fixed seat 2. A discharge hole 8 is opened in the middle of the fixed seat 2, and the valve 6 is located outside the discharge hole 8. The rotating ring 3 drives the long grooves 4 to rotate, the long grooves 4 drive the connecting shaft 5 inside them, and the connecting shaft 5 drives the valve 6. As the valve 6 moves, it gradually opens the discharge hole 8, at which point the material can be discharged. The operator can also freely adjust the discharge speed as needed. At the same time, since the discharge port is set at the center, there is no need to worry about material blockage. This solves the problem of easy blockage during material discharge, reduces the trouble of subsequent cleaning, improves the use effect of the gate valve, and adds the function of freely adjusting the discharge speed, thereby increasing the practicality of the gate valve.

[0025] Specifically, the top inner side of the fixed base 2 is provided with a discharge hole 8, and the sliding block 7 slides inside the sliding groove 9. Multiple sliding blocks 7 drive multiple valves 6 to move in a straight line along the edge of the sliding groove 9, thereby avoiding material leakage gaps while opening the discharge hole 8.

[0026] Furthermore, limit bars 71 are fixedly provided on both sides of the sliding block 7, and the limit bars 71 slide inside the sliding groove 9 on both sides. The limit bars 71 mainly limit the sliding block 7 and the valve 6.

[0027] Furthermore, a fixing ring 10 is fixedly installed at the bottom of the fixing base 2, and multiple screw holes are opened on the outer side of the fixing ring 10. The gate valve can be installed in the designated position through the fixing ring 10, which facilitates the installation of the gate valve.

[0028] It is worth noting that a connecting sleeve 11 is fixedly provided at the bottom of the rotating ring 3, and the connecting sleeve 11 is rotatably connected to the fixed base 2. The connecting sleeve 11 covers the top of the fixed base 2, thereby ensuring the connection between the fixed base 2 and the rotating ring 3, and also facilitating the sliding of the rotating ring 3.

[0029] It is worth noting that a push handle 12 is fixedly provided on the outer side of the rotating ring 3, and multiple reinforcing ribs are fixedly provided on the outer side of the push handle 12. The operator rotates the rotating ring 3 by pushing the push handle 12, and the reinforcing ribs can increase the friction.

[0030] It is worth mentioning that a base 13 is fixedly installed on the bottom surface of the hopper body 1.

[0031] The hopper body 1 is existing technology and will not be described in detail here. Additionally, this utility model also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail here. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle:

[0033] When using the anti-clogging gate valve, firstly, the fixed seat 2 and its management components are installed inside the hopper body 1 through the fixed ring 10. The base 13 is used to support the hopper body 1. When material needs to be discharged, the pusher position 12 is rotated. The pusher position 12 drives the rotating ring 3, the rotating ring 3 drives the long groove 4, the long groove 4 drives the connecting shaft 5 inside it, and the connecting shaft 5 drives the valve 6 to move linearly along the position of the sliding groove 9. The limiting strips 71 on both sides of the sliding block 7 slide inside the fixed seat 2 to limit it. As the valve 6 moves, the discharge hole 8 is gradually opened. The operator can freely adjust the discharge speed as needed. At the same time, since the discharge port is set at the center, the rotating ring 3 here is connected to the fixed seat 2 through the connecting sleeve 11, so there is no need to worry about material blockage. This utility model solves the problem of easy blockage during material discharge, reduces the trouble of subsequent cleaning, improves the use effect of the gate valve, and also adds the function of freely adjusting the discharge speed, thereby increasing the practicality of the gate valve.
