Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically a high-strength shock-resistant valve. Background Technology
[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Their types and specifications are quite numerous. Valves can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.
[0003] The prior art disclosed on the Chinese Patent Network (CN220523378 U) discloses a high-strength, shock-resistant valve. This valve utilizes the end face of a sealing body to tightly fit the end face of a water pipe. Even if vibration occurs due to excessive water flow velocity in the pipe, the end face of the sealing body can still provide excellent sealing between the water pipe and the connecting plate, preventing leakage due to vibration. However, the above technical solution has certain defects. The valve is connected to the pipeline by flanges at both ends. The threads required for the flanges will rust due to moisture (water overflowing during maintenance and disassembly), which makes it difficult to manually rotate the bolts, or even impossible to rotate them, requiring cutting. Therefore, a high-strength shock-resistant valve is proposed. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a high-strength, shock-resistant valve to solve the technical problems mentioned in the background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength shock-resistant valve, comprising a valve body, with fixing rings fixed at both ends of the valve body, a connecting ring connected to the end of each set of fixing rings, a positioning block fixed to the curved outer wall of the fixing ring, and two sets of semi-arc strips rotatably provided on the surface of the positioning block; Two sets of conical arc strips are fixed to the inner wall of the curved surface of each set of semi-arc strips. The outer wall of the curved surface of the connecting ring is provided with a second conical ring groove for the conical arc strips to enter. The outer wall of the curved surface of the fixing ring is provided with a first conical ring groove that matches the conical arc strips. The end face of the fixing ring is provided with a sealing rubber cylinder extending into the valve body. The front and rear surfaces of each set of semi-arc strips are rotatably connected with constraint arms. A positioning post is fixed on the inner side of each set of constraint arms near the lower end. The constraint arm is located at the end of the semi-arc strip away from the positioning block. The surface of the other set of semi-arc strips is provided with a notch at the position corresponding to the constraint arm.
[0006] As a preferred technical solution for a high-strength, shock-resistant valve according to this utility model, the end face of the fixing ring is provided with a mating ring groove, the inner wall of the mating ring groove is attached with a rubber pad, and the end face of the connecting ring is provided with a conical ring extending into the mating ring groove.
[0007] As a preferred technical solution for a high-strength, shock-resistant valve of this utility model, the inner side of the two sets of constraint arms is provided with a base shaft extending into the semi-arc strip, and the outer wall of the base shaft is connected to the semi-arc strip by a torsion spring.
[0008] As a preferred technical solution for a high-strength, shock-resistant valve according to this utility model, a chamfer is provided at the contact position between the inner edge of the connecting ring end face and the sealing rubber cylinder.
[0009] As a preferred technical solution for a high-strength, earthquake-resistant valve according to this utility model, the two sets of semi-arc strips form a ring and wrap around the outer wall of the joint between the connecting ring and the fixed ring. The two sets of semi-arc strips are rotatably set by a damping shaft and a positioning block.
[0010] As a preferred technical solution for a high-strength, shock-resistant valve according to this utility model, the curved outer wall of the sealing rubber cylinder is connected to the inner wall of the valve body by threads.
[0011] In summary, the present invention has the following main advantages: This invention utilizes two sets of semi-arc strips to complete the connection with the pipeline, making the connection process simple and efficient. At the same time, it generates relative forces between the two, making the connection more tightly sealed. In addition, with the cooperation of sealing rubber cylinder and rubber gasket, it can absorb the vibration generated by the water flow in the pipeline, ensuring that the valve body and pipeline connection does not vibrate and leak.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0015] The embodiments of this utility model will be described below based on its overall structure.
[0016] A high-strength, shock-resistant valve, such as Figures 1 to 5 As shown, the valve body 100 includes a valve body, with fixed rings 110 fixed at both ends. Each set of fixed rings 110 is connected to a connecting ring 120 at its end. A positioning block 112 is fixed to the curved outer wall of the fixed ring 110. Two sets of semi-arc strips 140 are rotatably provided on the surface of the positioning block 112. Two sets of conical arc strips 141 are fixed to the inner curved wall of each set of semi-arc strips 140. The outer curved wall of the connecting ring 120 is provided with a second conical ring groove 122 for the conical arc strips 141 to enter. The outer curved wall of the fixing ring 110 is provided with a first conical ring groove 113 that matches the conical arc strips 141. The end face of the fixing ring 110 is provided with a sealing rubber cylinder 130 extending into the valve body 100. The front and rear surfaces of each set of semi-arc strips 140 are rotatably connected with constraint arms 150. A positioning post 151 is fixed on the inner side of each set of constraint arms 150 near the lower end. The constraint arm 150 is located at the end of the semi-arc strip 140 away from the positioning block 112. The surface of the other set of semi-arc strips 140 is provided with a notch 142 at the position corresponding to the constraint arm 150. The end face of the fixing ring 110 is provided with a mating ring groove 111, and a rubber pad is attached to the inner wall of the mating ring groove 111. The end face of the connecting ring 120 is provided with a conical ring 123 extending into the mating ring groove 111.
[0017] When docking the valve body 100, first rotate the sealing rubber cylinder 130 into the valve body 100, with part of its end face located at the end of the fixing ring 110. At this time, the connecting ring 120 located at the end of the pipe is brought into contact with the fixing ring 110 and aligned, with its conical ring 123 located in the docking ring groove 111. Then, rotate the two sets of semi-arc strips 140 around the contact point with the positioning block 112. The conical arc strips 141 on their inner walls enter the first conical ring groove 113 and the second conical ring groove 122 respectively, generating a lateral squeezing force on the connecting ring 120, driving the connecting ring 120 closer to the end of the fixing ring 110. The conical ring 123 will squeeze the rubber pad in the docking ring groove 111 to deform, so that the two are in a sealed state until the ends of the two sets of semi-arc strips 140 are in contact. Before the two sets of semi-arc strips 140 come into contact, an external force needs to be applied to the constraint arm 150 toward the end away from the semi-arc strip 140. When the ends of the two sets of semi-arc strips 140 come into contact, the constraint arm 150 is pushed to reverse and return to its original position, and the positioning pin 151 rotates into the notch 142, thus locking the ends of the two sets of semi-arc strips 140. This ensures that the fixing ring 110 and the connecting ring 120 are stably connected. Together with the sealing rubber cylinder 130 and the rubber pad, the vibration generated by the water flow is absorbed, so that the valve body will not easily leak due to vibration.
[0018] Please refer to this carefully. Figure 5 The inner side of the two sets of constraint arms 150 is provided with a base shaft extending into the semi-arc strip 140, and the outer wall of the base shaft is connected to the semi-arc strip 140 by a torsion spring.
[0019] This causes the constraint arm 150 to rotate around the base axis as the base point. As the rotation occurs, the torsion spring is compressed, which can self-drive the constraint arm 150 to reverse and return to its original position.
[0020] Please refer to this carefully. Figure 4 A chamfer 121 is provided at the contact position between the inner edge of the end face of the connecting ring 120 and the sealing rubber cylinder 130.
[0021] The chamfer 121 fits tightly against the end face of the sealing rubber cylinder 130, ensuring a tight seal at the joint and preventing leakage.
[0022] Please refer to this carefully. Figure 1 and Figure 3 Two sets of semi-arc strips 140 form a ring and wrap around the outer wall of the joint between the connecting ring 120 and the fixed ring 110. The two sets of semi-arc strips 140 are rotatably set by the damping shaft and the positioning block 112.
[0023] This ensures a sealing effect on the outer wall of the joint, while the damping shaft stabilizes the semi-arc strip 140 at a specified position, thus making it convenient to connect the two sets of semi-arc strips 140 to the outer wall of the connecting ring 120 and the fixing ring 110.
[0024] Please refer to this carefully. Figure 2 The curved outer wall of the sealing rubber cylinder 130 is connected to the inner wall of the valve body 100 by threads.
[0025] The use of threaded connection makes it easy to assemble and disassemble the sealing rubber cylinder 130 and the valve body 100.
[0026] When using the valve body 100, first rotate the sealing rubber cylinder 130 into the valve body 100, with part of its end face located at the end of the fixing ring 110. At this time, the connecting ring 120 located at the end of the pipe is brought into contact with the fixing ring 110 and aligned, with its conical ring 123 located in the docking ring groove 111. Then, rotate the two sets of semi-arc strips 140 around the contact point with the positioning block 112. The conical arc strips 141 on their inner walls enter the first conical ring groove 113 and the second conical ring groove 122 respectively, generating a lateral squeezing force on the connecting ring 120, driving the connecting ring 120 closer to the end of the fixing ring 110. The conical ring 123 will squeeze the rubber pad in the docking ring groove 111 to deform, so that the two are in a sealed state until the ends of the two sets of semi-arc strips 140 are in contact. Before the two sets of semi-arc strips 140 come into contact, an external force needs to be applied to the constraint arm 150 toward the end away from the semi-arc strip 140. When the ends of the two sets of semi-arc strips 140 come into contact, the constraint arm 150 is pushed to reverse and return to its original position, and the positioning pin 151 rotates into the notch 142, thus locking the ends of the two sets of semi-arc strips 140. This ensures that the fixing ring 110 and the connecting ring 120 are stably connected. In conjunction with the sealing rubber cylinder 130 and the rubber pad to absorb the vibration generated by the water flow, the valve body will not easily leak due to vibration. The parts not involved in this device are the same as or can be implemented using existing technology.
