Description

Technical Field

[0001] This utility model relates to the field of spiral gate valve technology, specifically a one-way manual spiral gate valve for a smart loading system for bulk materials. Background Technology

[0002] The intelligent loading system for bulk materials is mainly used for the quantitative loading of bulk materials and other powdery materials. The system has advanced principles, simple structure, accurate measurement, reliable operation and convenient maintenance. In order to ensure the reliability of the intelligent loading system for bulk materials, two types of valves, electric valves and manual valves, are usually connected in series inside the material conveying pipeline to make the material conveying process more controllable. The manual valve used in the intelligent loading system for bulk materials is usually a screw gate valve.

[0003] The existing one-way manual spiral gate valve closes by rotating the handwheel clockwise to drive the valve stem to lift the gate, and opens by rotating it counterclockwise.

[0004] When closing existing one-way manual screw gate valves, the thickness of the gate can cause material to accumulate between the gate and the inner wall of the valve body, preventing the gate from closing completely. To avoid this, some one-way manual screw gate valves have a sharp angle on the lower side of the gate to facilitate cutting into the material and prevent the gate from not closing completely. However, when opening the gate, the narrowing of the lower side of the gate can cause gaps to appear between the gate and the sealing rubber gasket, resulting in poor sealing between the gate and the valve body. We propose a one-way manual screw gate valve for intelligent loading systems for bulk materials. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a one-way manual spiral gate valve for a smart loading system for bulk materials. By adjusting the mechanism, the deflector moves towards the inside of the valve body during the upward movement of the gate, thereby applying pressure to the sealing rubber gasket and preventing gaps from appearing between the gate and the sealing rubber gasket. This improves the sealing performance between the gate and the valve body and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a one-way manual spiral gate valve for an intelligent loading system for bulk materials, comprising a valve body, a sealing rubber gasket fixedly connected inside the valve body, a gate plate slidably connected inside the sealing rubber gasket, and an adjustment mechanism;

[0007] Adjustment mechanism: It includes a fixed rod, a lever, a connecting rod, and a torsion spring. The fixed rod is fixedly connected to the upper inner side of the valve body. A sleeve is rotatably connected to the outer surface of each fixed rod. A lever is fixedly connected to the lower outer surface of each sleeve. A connecting rod is fixedly connected to the upper outer surface of each sleeve. A torsion spring is sleeved on the left side of the outer surface of each fixed rod. The left end of each torsion spring is fixedly connected to the outer surface of the horizontally adjacent fixed rod. The right end of each torsion spring is fixedly connected to the outer surface of the horizontally adjacent sleeve. Through the adjustment mechanism, the lever moves towards the inside of the valve body during the upward movement of the gate, thereby applying pressure to the sealing rubber gasket and preventing gaps from appearing between the gate and the sealing rubber gasket, thus improving the sealing performance between the gate and the valve body.

[0008] Furthermore, a screw is rotatably connected to the upper inner side of the valve body, and a threaded sleeve is fixedly connected to the front surface of the gate. The lower end of the screw is threaded into the inside of the threaded sleeve, driving the gate to move.

[0009] Furthermore, a handwheel is fixedly connected to the upper end of the screw to facilitate rotation of the screw.

[0010] Furthermore, the right surface of the valve body is provided with an avoidance groove, and an indicator block is slidably connected inside the avoidance groove. The left end of the indicator block is fixedly connected to the upper side of the right surface of the gate. The right surface of the valve body is provided with evenly distributed scale lines to indicate the opening degree of the gate.

[0011] Furthermore, the upper inner surface of the valve body is fixedly connected with uniformly distributed limit rods, and the gate is slidably connected between the four limit rods to provide additional sliding support for the gate, thereby sharing the stress borne by the gate and the service life of the gate.

[0012] Furthermore, the lower edge of the gate is a sharp acute angle, and the upper edge of the gate is a wide sealing surface, which facilitates the closure of the gate and prevents the gate from failing to close completely due to the compression of materials when closing.

[0013] Furthermore, the valve body has evenly distributed threaded holes on both its front and rear surfaces to facilitate connection with an external material conveying system.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This one-way manual screw gate valve for intelligent loading system of bulk materials has the following advantages:

[0015] By adjusting the mechanism, the pawl moves towards the inside of the valve body as the gate moves upward, thereby applying pressure to the sealing rubber gasket and preventing gaps from forming between the gate and the sealing rubber gasket, thus improving the sealing performance between the gate and the valve body.

[0021] 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.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a one-way manual spiral gate valve for an intelligent loading system for bulk materials, including a valve body 1. A sealing rubber gasket 11 is fixedly connected inside the valve body 1, and a gate plate 2 is slidably connected inside the sealing rubber gasket 11. The lower edge of the gate plate 2 is a sharp acute angle, and the upper edge of the gate plate 2 is a wide sealing surface. A screw 4 is rotatably connected to the upper side inside the valve body 1. A threaded sleeve 3 is fixedly connected to the front surface of the gate plate 2 (the lower surface of the threaded sleeve 3 is between the inner wall of the valve body 1 and the screw...). A bellows is fixedly connected between the threaded sleeve 3 and the inner upper surface of the valve body 1. The bellows are fitted onto the outer surface of the screw 4 to protect it and prevent external impurities from adhering to its outer surface and causing it to jam. The lower end of the screw 4 is threaded into the inside of the threaded sleeve 3, and a handwheel 5 is fixedly connected to the upper end of the screw 4. When material needs to be conveyed, rotating the handwheel 5 rotates the screw 4, causing the threaded sleeve 3 to move upwards, which in turn moves the gate plate 2 upwards. The valve body 1 is designed to allow material transport by opening the lower inner side of the valve body 1. A clearance groove 8 is provided on the right surface of the valve body 1. An indicator block 9 is slidably connected inside the clearance groove 8. The left end of the indicator block 9 is fixedly connected to the upper right surface of the gate plate 2. The right surface of the valve body 1 is provided with evenly distributed scale lines 10. When the gate plate 2 moves, it will drive the indicator block 9 to move inside the clearance groove 8. By matching the position of the indicator block with the scale lines, the degree of opening of the one-way manual screw gate valve can be determined (assuming the maximum movement distance of the gate plate is a, the length of the scale line is also a, the scale line is 50 divisions, the length of each division is a / 50, and each division is two percent). The upper inner surface of the valve body 1 is fixedly connected with evenly distributed limit rods 6. The gate plate 2 is slidably connected between the four limit rods 6. The front and rear surfaces of the valve body 1 are provided with evenly distributed threaded holes. The one-way manual screw gate valve is connected to the conveying pipeline of the external bulk material intelligent loading system through the threaded holes on the front and rear sides. The valve body 1 also includes an adjustment mechanism 7.

[0023] Adjustment mechanism 7 includes a fixed rod 71, a lever 72, a connecting rod 73, and a torsion spring 74. The fixed rod 71 is fixedly connected to the upper inner side of the valve body 1. A sleeve is rotatably connected to the outer surface of each fixed rod 71. The lever 72 is fixedly connected to the lower outer surface of each sleeve. The connecting rod 73 is fixedly connected to the upper outer surface of each sleeve. A torsion spring 74 is sleeved on the left side of the outer surface of each fixed rod 71. (The fixed rod 71 is fixedly connected to the inside of the valve body 1 by bolts. The bolts can be removed to disassemble the entire adjustment mechanism 7, allowing for periodic replacement of the torsion spring 74 and preventing long-term use of the torsion spring 74.) (The problem of reduced torque or failure after use occurs). The left end of the torsion spring 74 is fixedly connected to the outer surface of the horizontally adjacent fixed rod 71, and the right end of the torsion spring 74 is fixedly connected to the outer surface of the horizontally adjacent sleeve. During the upward movement of the gate plate 2, the upper end of the gate plate 2 presses the connecting rod 73 upward, causing the connecting rod 73 to rotate around the central axis of the rotating rod 71 in a direction away from the valve body 1. When the sleeve rotates, it drives the paddle 72 to move closer to the inside of the valve body 1. The paddle 72 presses the sealing rubber pad 11, so that the sealing rubber pad is tightly attached to the gate plate 2, thereby ensuring the sealing between the gate plate 2 and the valve body 1.

[0024] The working principle of the one-way manual screw gate valve for a smart bulk material loading system provided by this utility model is as follows: When using this one-way manual screw gate valve for a smart bulk material loading system, the valve is connected to the conveying pipeline of the external smart bulk material loading system through the threaded holes on both the front and rear sides. When material needs to be conveyed, the handwheel 5 is turned. The rotation of the handwheel 5 drives the screw 4 to rotate, causing the threaded sleeve 3 to move upward, which in turn moves the gate plate 2 upward, thus making the lower part of the valve body 1 a passage, thereby conveying the material. During the upward movement of the gate plate 2, the upper end of the gate plate 2 presses upward against the connecting rod. 73. The connecting rod 73 rotates around the central axis of the rotating rod 71 in a direction away from the valve body 1. When the sleeve rotates, it drives the paddle 72 to move closer to the inside of the valve body 1. The paddle 72 squeezes the sealing rubber pad 11, so that the sealing rubber pad is tightly attached to the gate 2, thereby ensuring the sealing between the gate 2 and the valve body 1. When the gate 2 moves, it will drive the indicator block 9 to move inside the clearance groove 8. By corresponding the position of the indicator block with the scale line, the opening degree of the one-way manual spiral gate valve can be determined (let the maximum moving distance of the gate be a, the length of the scale line be a, the scale line be 50 divisions, the length of each division be a / 50, and each division be two percent).

[0025] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
