Description

Technical Field

[0001] This utility model relates to the field of ceramic gate valve technology, and in particular to a double-sealed ceramic gate valve. Background Technology

[0002] A ceramic gate valve is an industrial gate valve that uses high-performance engineering ceramic materials as key sealing components or main flow-through components. It controls the flow of media in a pipeline by vertically raising and lowering the gate. Its core sealing surfaces (such as the gate and valve seat) are made of high-hardness, corrosion-resistant, and wear-resistant ceramic materials, making it suitable for pipeline systems that transport media containing solid particles, corrosive media, or under high-temperature or high-wear conditions.

[0003] A pneumatic double gate valve, as disclosed in CN213017803U, includes a valve body and a cylinder. The valve body has inlet and outlet ports and contains a valve plate driven by the cylinder. The valve plate is mounted on a piston cylinder, with an air outlet at the end furthest from the cylinder. The cylinder is connected to the piston cylinder via a first piston rod. The piston cylinder is coaxial with the first piston rod, and the end furthest from the cylinder is connected to the valve body via a second piston rod. The air outlet communicates with the inner cavity of the piston cylinder. According to the technical solution provided in this application, by installing the piston cylinder between the first piston rod and the valve body, while the valve plate is closed, the second piston rod is pressed into the piston cylinder, causing the gas inside the piston cylinder to be discharged through the air outlet. This gas discharge process removes particulate matter adsorbed on the inlet and outlet ports. However, because the valve plate of this pneumatic double gate valve is in close contact with the inner wall of the valve body when it moves, the friction is severe, which can easily cause wear between the valve body and the valve plate, thereby affecting the sealing performance, shortening the service life and increasing maintenance costs.

[0004] Therefore, a double-sealed ceramic gate valve has now been developed that can retract the valve plate inward, reduce friction between it and the valve body, and extend its service life. Utility Model Content

[0005] To overcome the shortcomings of existing pneumatic double gate valves, where the valve plate moves in close contact with the inner wall of the valve body, resulting in severe friction, wear between the valve body and the valve plate, and consequently affecting sealing performance, shortening service life, and increasing maintenance costs, this utility model provides a double-sealed ceramic gate valve that can retract the valve plate inward, reduce friction between it and the valve body, and extend service life.

[0006] Technical solution: A double-sealed ceramic gate valve includes a valve body, a mounting block, a cylinder, a connecting shaft, a mounting sleeve, a sleeve, an elastic element, a square tube, a valve plate, a sealing ring, a slide rail, and a detection component. The mounting block is connected to the upper side of the valve body's middle section. A cylinder is connected to the upper side of the mounting block. A connecting shaft is connected to the telescopic end of the cylinder. A mounting sleeve is connected to the lower side of the connecting shaft. A sleeve is connected to the mounting sleeve. Square tubes are slidably connected to both sides of the sleeve. Elastic elements connect the square tubes to the sleeves. A valve plate is connected to the side of the square tubes that are furthest from each other. A sealing ring is connected to the side of the valve plates that are furthest from each other. Two slide rails are connected to the inner side of the valve body's middle section. The slide rails pass through adjacent square tubes. A detection component capable of detecting fluid flow rate is provided on the mounting sleeve.

[0007] In addition, it is particularly preferred that flanges are provided on both the left and right sides of the valve body.

[0008] Furthermore, it is particularly preferred that the elastic element be a spring.

[0009] In addition, it is particularly preferred that the tube also includes auxiliary wheels, with two auxiliary wheels rotatably connected to the square tube on the left and right, and the auxiliary wheels contacting and engaging with the adjacent slide rail.

[0010] Furthermore, it is particularly preferred that the detection assembly includes a connecting sleeve, a flow rate sensor, and a mounting cylinder, with the connecting sleeve connected to the lower side of the mounting sleeve, the flow rate sensor connected to the lower side of the connecting sleeve, and the mounting cylinder connected to the lower side of the middle part of the valve body, with the flow rate sensor located inside the mounting cylinder.

[0011] Furthermore, it is particularly preferred that the cylinder, flow sensor, and processor are electrically connected via a control module.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a starting cylinder to drive the connecting shaft and mounting sleeve to move upward, so that the square tube moves upward along the slide rail. The auxiliary wheel assists the square tube to move on the slide rail. The slide rail guides the square tube to move towards the center. The spring is compressed and contracted, which causes the valve plate and sealing ring to move inward and not contact the inner wall of the valve body, thus achieving the effect of reducing friction with the valve body and extending service life.

[0013] 2. When the mounting sleeve of this utility model moves upward, it drives the flow rate sensor to move upward and detach from the mounting cylinder. When the fluid flows through, the flow rate sensor detects the fluid flow rate. After the mounting sleeve moves downward and resets, the flow rate sensor moves down into the mounting cylinder. Then, the sealing cover is removed to drain the fluid from the mounting cylinder. This achieves the effect of reducing the damage of the fluid to the flow rate sensor and extending the service life of the flow rate sensor. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] A double-sealed ceramic gate valve, such as Figures 1-4 As shown, the device includes a valve body 1, mounting block 2, cylinder 3, connecting shaft 4, mounting sleeve 5, sleeve 6, elastic element, square tube 8, auxiliary wheel 9, valve plate 10, sealing ring 11, slide rail 15, and detection assembly. The mounting block 2 is connected to the upper middle part of the valve body 1. Flanges are provided on both the left and right sides of the valve body 1 for easy pipe connection. A cylinder 3 is connected to the upper part of the mounting block 2. A connecting shaft 4 is connected to the telescopic end of the cylinder 3. A mounting sleeve 5 is connected to the lower part of the connecting shaft 4. A sleeve 6 is connected to the mounting sleeve 5. The sleeve 6 has two... Each part is slidably connected to a square tube 8, and each square tube 8 is connected to a sleeve 6 by an elastic element, which is a spring 7. Each square tube 8 is rotatably connected to two auxiliary wheels 9. Each square tube 8 is connected to a valve plate 10 on the side away from each other, and each valve plate 10 is connected to a sealing ring 11 on the side away from each other. The valve body 1 is connected to two slide rails 15 on the inner side of the middle part, and each slide rail 15 passes through the adjacent square tube 8. Each auxiliary wheel 9 contacts and cooperates with the adjacent slide rail 15. The mounting sleeve 5 is equipped with a detection component.

[0021] like Figure 1 and Figure 4 As shown, the detection assembly includes a connecting sleeve 12, a flow rate sensor 13, and a mounting cylinder 14. The connecting sleeve 12 is connected to the lower side of the mounting sleeve 5, and the flow rate sensor 13 is connected to the lower side of the connecting sleeve 12. The cylinder 3, the flow rate sensor 13, and the processor are electrically connected through a control module. The mounting cylinder 14 is connected to the lower side of the middle part of the valve body 1. The flow rate sensor 13 is located inside the mounting cylinder 14. A sealing cover is detachably provided on the lower side of the mounting cylinder 14.

[0022] When using this utility model, the valve body 1 is first installed between the pipes. When fluid needs to flow, the processor starts the cylinder 3 through the control module, which drives the connecting shaft 4 and the mounting sleeve 5 to move upward, so that the square tube 8 moves upward along the slide rail 15. The auxiliary wheel 9 assists the square tube 8 to move on the slide rail 15. Guided by the slide rail 15, the square tube 8 moves towards the middle, and the spring 7 is compressed and contracted, which causes the valve plate 10 and the sealing ring 11 to move inward and not contact the inner wall of the valve body 1, thereby reducing friction with the valve body 1 and extending service life. Then the fluid flows through the valve body 1 between the pipes. When the valve body 1 needs to be closed, the mounting sleeve 5 and the sleeve 6 move downward, the square tube 8 moves outward along the slide rail 15, and the spring 7 rebounds, causing the valve plate 10 and the sealing ring 11 to move outward and contact the valve body 1, thus providing a double seal for the valve body 1.

[0023] When the mounting sleeve 5 moves upward, it drives the flow rate sensor 13 to move upward away from the mounting cylinder 14. When the fluid flows through, the flow rate sensor 13 detects the fluid flow rate. After the mounting sleeve 5 moves downward to reset, the flow rate sensor 13 moves down into the mounting cylinder 14. Then the sealing cover is removed to drain the fluid from the mounting cylinder 14, thereby reducing the damage of the fluid to the flow rate sensor 13 and extending the service life of the flow rate sensor 13.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
