A high-pressure resistant valve plate structure for a ship

Abstract

This utility model discloses a marine high-pressure resistant valve plate structure, specifically relating to the field of valve plate technology. It includes a valve plate mechanism and external components. The external components are mounted on the outer diameter surface of the valve plate mechanism. The valve plate mechanism comprises a body component, a connecting component, and a positioning component. The connecting component is mounted on the side of the body component, and the positioning component is placed below the connecting component. The body component employs a three-layer valve plate structure and a reinforcing rib design, which not only strengthens the valve plate's resistance to high pressure but also, because the inner valve plate uses a resilient rubber material, it can absorb pressure waves, thereby reducing the risk of cracking due to excessive local pressure caused by stress concentration. The outer valve plate of the three-layer structure is made of stainless steel, which has good mechanical strength and corrosion resistance, allowing it to directly withstand external pressure and resist seawater erosion.

Description

Technical Field

[0001] This utility model relates to the field of valve plate technology, and more specifically, to a marine high-pressure resistant valve plate structure. Background Technology

[0002] A valve plate is a key component widely used in fluid control systems. It is usually a metal or non-metal plate with a specific shape and various holes, channels and mounting grooves of different sizes and shapes. These structures are usually used to install other valve components such as valve cores, valve seats and sealing rings, and through the cooperation of these components, the precise control of parameters such as fluid direction, pressure and flow rate can be achieved.

[0003] A search revealed that publication number CN202302018U discloses a valve plate for a lifting valve of a bag filter, comprising an upper plate and a lower plate stacked together, the diameter of the upper plate being smaller than the diameter of the lower plate. This design is simple in structure, low in manufacturing cost, structurally stable, and ensures a tight seal between the valve plate and the valve seat. During the development of this invention, the inventors discovered the following problems with the existing technology:

[0004] Traditional valve plates are typically designed for low-pressure applications and have a limited pressure tolerance range. When the system pressure exceeds their rated pressure, ordinary valve plates may deform or crack, leading to valve failure and inability to control fluid properly. Furthermore, the sealing materials used in existing valve plates are relatively weak in terms of high pressure resistance, high temperature resistance, and chemical corrosion resistance. Under high pressure and corrosive media conditions, the sealing materials are prone to aging, deformation, and damage, thus affecting the overall sealing performance of the valve plate. Therefore, a marine high-pressure resistant valve plate structure is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a marine high-pressure resistant valve plate structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a marine high-pressure resistant valve plate structure, comprising a valve plate mechanism and an external component, wherein the external component is mounted on the outer diameter surface of the valve plate mechanism, and the valve plate mechanism includes a body component, a connecting component and a positioning component, wherein the connecting component is mounted on the side of the body component, and the positioning component is placed below the connecting component.

[0007] Preferably, the body assembly includes a first outer valve plate, an inner valve plate, a second outer valve plate, and a reinforcing rib. The inner valve plate is placed on the side of the first outer valve plate, and the second outer valve plate is placed on the side of the inner valve plate away from the first outer valve plate. The reinforcing rib is installed on the side of the second outer valve plate away from the inner valve plate.

[0008] Preferably, the connecting assembly includes a double-ended bolt, a nut, and a washer, with the washer placed on the outer diameter surface of the double-ended bolt and the nut placed on the side of the washer.

[0009] Preferably, the positioning component includes a positioning pin, a first positioning hole block, and a second positioning hole block, wherein the first positioning hole block is placed on the outer diameter surface of the positioning pin, and the second positioning hole block is placed on the side of the first positioning hole block.

[0010] Preferably, the external component includes a first sealing ring, a second sealing ring, and a valve stem connection hole block, wherein the second sealing ring is placed on the side of the first sealing ring, and the valve stem connection hole block is placed on top of the second sealing ring.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Compared with the prior art, this marine high-pressure resistant valve plate structure adopts a three-layer valve plate structure and a reinforcing rib design in the main body component. This not only strengthens the valve plate's resistance to high pressure, but also reduces the risk of rupture caused by excessive local pressure due to stress concentration because the inner valve plate is made of rubber with good toughness. The outer valve plate of the three-layer valve plate structure is made of stainless steel, which has good mechanical strength and corrosion resistance, and can directly withstand external pressure and resist seawater erosion.

[0013] 2. Compared with existing technologies, this marine high-pressure resistant valve plate structure uses a combination of lip seal and O-ring seal for the sealing ring. This not only allows it to better fit the sealing surface under high pressure to prevent media leakage, but also plays an auxiliary sealing and buffering role, thereby improving the reliability of the seal. The sealing ring is made of fluororubber, because fluororubber has excellent oil resistance and chemical corrosion resistance, and can maintain good elasticity and sealing performance in high-pressure environments with corrosive media, enabling it to operate normally at sea.

The external component 2 is mounted on the outer diameter surface of the valve plate mechanism 1. The valve plate mechanism 1 includes a body component 3, a connecting component 4, and a positioning component 5. The connecting component 4 is mounted on the side of the body component 3, and the positioning component 5 is placed below the connecting component 4.

[0022] When assembling the valve plate, the worker first needs to assemble the valve plate mechanism 1. When assembling the valve plate mechanism 1, the worker needs to position the main body component 3 using the positioning component 5, and then fix it using the connecting component 4. After assembly, the worker needs to install the external component 2 onto the outer diameter surface of the valve plate mechanism 1 to ensure that when the valve plate is installed inside the valve, it can fit tightly against the inner wall of the valve when it is in the closed state.

[0023] Example 2

[0024] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0025] In a preferred embodiment, the body assembly 3 includes a first outer valve plate 6, an inner valve plate 7, a second outer valve plate 8, and a reinforcing rib 9. The inner valve plate 7 is placed on the side of the first outer valve plate 6, and the second outer valve plate 8 is placed on the side of the inner valve plate 7 away from the first outer valve plate 6. The reinforcing rib 9 is welded onto the side of the second outer valve plate 8 away from the inner valve plate 7. When the worker assembles the body assembly 3, the reinforcing rib 9 is welded to the outer valve plate, and then the first outer valve plate 6 and the second outer valve plate 8 are placed on both sides of the inner valve plate 7 by the positioning assembly 5.

[0026] In a preferred embodiment, the connecting assembly 4 includes a double-ended bolt 10, a nut 11, and a washer 12. The washer 12 is placed on the outer diameter surface of the double-ended bolt 10, and the nut 11 is placed on the side of the washer 12. When the worker fixes the main body assembly 3, the worker needs to insert the double-ended bolt 10 into the connecting hole of the main body assembly 3, then put the washer 12 into the outer diameter surface of the double-ended bolt 10 on both sides, and finally use the nut 11 to fix it.

[0027] In a preferred embodiment, the positioning component 5 includes a positioning pin 13, a first positioning hole block 14, and a second positioning hole block 15. The first positioning hole block 14 is placed on the outer diameter surface of the positioning pin 13, and the second positioning hole block 15 is placed on the side of the first positioning hole block 14. When fixing the body component 3, the worker needs to pass the body component 3 with the positioning pin 13 through the first positioning hole block 15 and the second positioning hole block 16 respectively to achieve the positioning of the body component 3.

[0028] In a preferred embodiment, the external component 2 includes a first sealing ring 16, a second sealing ring 17, and a valve stem connecting hole block 18. The second sealing ring 17 is placed on the side of the first sealing ring 16, and the valve stem connecting hole block 18 is placed on top of the second sealing ring 17. After the main body component 3 is connected, the worker needs to put the first sealing ring 16 and the second sealing ring 17 on both sides of the main body component 3, and then fix the valve stem connecting hole block 18 on top of the main body component 3 with bolts.

[0029] The working process of this utility model is as follows: First, when the worker assembles the valve plate, the valve plate mechanism 1 needs to be assembled first. When assembling the valve plate mechanism 1, the reinforcing rib 9 is first welded to the outer valve plate. Then, the worker needs to pass the first outer valve plate 6 with positioning pin 13 through the first positioning hole block 15 of the inner valve plate 7 and the second positioning hole block 16 of the second outer valve plate 8 to achieve the positioning of the main body component 3. Then, it is fixed by the connecting component 4. When the worker fixes the main body component 3, the worker needs to insert the double-ended bolt 10 into the connecting hole of the main body component 3, and then put the washer 12 into the outer diameter surface of the exposed sides of the double-ended bolt 10. Finally, it is fixed with the nut 11. After the main body component 3 is connected, the worker needs to put the first sealing ring 16 and the second sealing ring 17 on the outer diameter surface of the first outer valve plate 6 and the second outer valve plate 8 respectively. Then, the valve stem connecting hole block 18 is fixed to the top of the inner valve plate 7 by bolts. The above is the working principle of this marine high-pressure resistant valve plate structure.
