Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to stainless steel gaskets with positioning holes. Background Technology

[0002] In the fields of machinery, automotive industry, petrochemical industry, rail transportation, aerospace and hydraulic and pneumatic systems, gaskets are mainly used for sealing, preventing loosening and balancing pressure at the connection parts of equipment components. They are suitable for various complex working conditions such as high and low pressure, vibration and corrosion, and are key supporting components to ensure the sealing performance and structural stability of equipment.

[0003] Traditional stainless steel gaskets with positioning holes have a single function, providing only basic sealing and positioning. When faced with complex working conditions such as vibration and pressure fluctuations, they are prone to sealing failure and positioning misalignment due to a lack of adaptive adjustment capabilities, thus failing to ensure stable equipment operation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a stainless steel gasket with a positioning hole, which aims to improve the problem of traditional gaskets being unable to adapt to various complex working conditions, resulting in sealing failure and positioning misalignment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel washer with positioning holes, comprising a washer, a protrusion fixedly connected to the surface of the washer, a boss fixedly connected to the outer wall of the washer, an elastic lip fixedly connected to the surface of the boss, a piston slidably connected to the inner wall of the washer, a second spring provided on the inner wall of the washer, a bushing fixedly connected to the inner wall of the washer, a support column fixedly connected to the inner wall of the washer, a compensation ring fixedly connected to the inner wall of the washer, a sleeve fixedly connected to the inner wall of the washer, a positioning pin slidably connected to the inner wall of the sleeve, a first spring provided on the inner wall of the positioning pin, a limit pin slidably connected to the inner wall of the positioning pin, and a detection component provided inside the support column.

[0006] According to the above technical solution, grease is filled into the oil groove on the inner wall of the bushing to reduce wear between the bolt and the bushing. Simultaneously, as the bolt passes through the bushing, the grease can form an adhesion layer between the bolt and the bushing, preventing fluid from seeping out of the equipment. The protrusions on the gasket surface can form a multi-point contact seal with the equipment surface, enhancing adaptability to minor scratches on the sealing surface. The boss can enhance the fit with the sealing surface and adapt to different sealing groove depths. When the equipment is operating, the increased operating pressure leads to increased pressure on the gasket; the support column can disperse the pressure, preventing the gasket from undergoing excessive deformation and causing a decrease in sealing flatness. When the pressure increases, the contact area between the piston and the sealing surface increases, dispersing local stress and preventing damage to the gasket. When the operating pressure decreases, the second spring inside the piston chamber ensures sufficient contact between the piston and the sealing surface, achieving the required sealing effect. When equipment vibration causes the sealing surface to move, the compensation ring can compensate for the displacement gap in real time through the compression or rebound of the protruding part, preventing the sealing surface from detaching. The elastic lip can also vibrate with the equipment during vibration, maintaining the gasket's sealing effect. Through the above structure, adaptive sealing adjustment under various operating conditions can be achieved, improving the gasket's stability and adaptability to operating conditions.

[0007] Preferably, the detection component includes a warning pin, the outer wall of which is slidably connected to the inner wall of the support column, the inner wall of the support column is provided with a compression spring, the inner wall of the support column is provided with a third spring, the inner wall of the support column is slidably connected to a trigger pin, and the inside of the washer is slidably connected to a detection rod.

[0008] Preferably, the inner wall of the bushing is provided with an oil groove, the inner wall of the sleeve is provided with an L-shaped groove, and the surface of the limiting pin is slidably connected in the L-shaped groove.

[0009] Preferably, the surface of the washer is provided with a piston cavity, the surface of the second spring is slidably connected to the piston cavity, and the surface of the piston is slidably connected to the piston cavity.

[0010] Preferably, the surface of the washer is provided with a pressure balancing groove, the surface of the washer is provided with a first sliding groove, and the surface of the compensation ring is fixedly connected to the first sliding groove.

[0011] Preferably, the surface of the support column is provided with a second sliding groove, the surface of the trigger pin is slidably connected to the second sliding groove, and the surface of the warning pin is slidably connected to the second sliding groove.

[0012] Preferably, the inside of the washer is provided with a third sliding groove, and the surface of the detection rod is slidably connected in the third sliding groove.

[0013] Preferably, the surface of the washer has a tapered guide opening.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the oil groove on the inner wall of the bushing is filled with grease to prevent fluid leakage inside the equipment. The protrusions on the surface of the gasket achieve multi-point contact sealing. The support column disperses pressure to prevent excessive deformation of the gasket. The piston adjusts the contact area and sealing performance according to the increase or decrease of pressure. When the equipment vibrates, the compensation ring compensates for the displacement gap in real time to prevent the sealing surface from detaching, realizing multi-condition adaptive sealing and improving the stability and adaptability of the gasket.

[0016] 2. In this utility model, the trigger pin holds the warning pin in place. When the vibration amplitude of the equipment exceeds the elastic limit set by the third spring, the trigger pin shakes and disengages from the warning pin. The compression spring below the warning pin resets and lifts the warning pin. When fluid seeps into the equipment, it flows into the third chute and pushes out the detection rod under the action of the fluid, thereby realizing the detection of the equipment operation and ensuring stable operation of the equipment.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-3 An embodiment of this utility model provides a stainless steel washer with positioning holes, comprising washer 1, a protrusion 2 fixedly connected to the surface of washer 1, a boss 3 fixedly connected to the outer wall of washer 1, an elastic lip 4 fixedly connected to the surface of boss 3, a piston 5 slidably connected to the inner wall of washer 1, a second spring 14 provided on the inner wall of washer 1, a bushing 10 fixedly connected to the inner wall of washer 1, a support column 6 fixedly connected to the inner wall of washer 1, a compensation ring 12 fixedly connected to the inner wall of washer 1, a sleeve 9 fixedly connected to the inner wall of washer 1, a positioning pin 7 slidably connected to the inner wall of sleeve 9, a first spring 13 provided on the inner wall of positioning pin 7, a limit pin 8 slidably connected to the inner wall of positioning pin 7, and a detection component provided inside the support column 6.

[0027] Specifically, by filling the oil groove on the inner wall of bushing 10 with grease, the wear between the bolt and bushing 10 can be significantly reduced, extending the service life of gasket 1. The grease also forms a tight adhesion layer between the bolt and bushing 10, effectively preventing internal fluid leakage and providing double protection for the sealing performance. The boss 3 can adapt to various sealing groove depths, resulting in a higher fit between gasket 1 and the sealing surface. The protrusions 2 on the surface of gasket 1 can form multi-point contact seals with the equipment surface, adapting to minor scratches on the sealing surface and significantly improving sealing tolerance. When the equipment operating pressure increases, the support column 6 can promptly disperse the pressure, preventing excessive deformation of gasket 1 due to pressure. Piston 5... As the pressure increases, the contact area with the sealing surface increases, dispersing local stress to protect gasket 1. When the pressure decreases, the second spring 14 inside the piston chamber ensures that the piston 5 is in full contact with the sealing surface, maintaining a stable sealing effect. In the face of sealing surface movement caused by equipment vibration, the compensation ring 12 can compensate for the displacement gap in real time through the compression and rebound of the protruding part, preventing the sealing surface from detaching. The elastic lip 4 vibrates with the equipment during vibration, maintaining a continuous seal. The multi-structure collaborative design ultimately realizes the adaptive sealing adjustment of gasket 1 under various complex working conditions, enhancing the operational stability and working condition adaptability of gasket 1, and providing key guarantees for the long-term reliable operation of the equipment.

[0028] Reference Figure 6The detection component includes a warning pin 11, the outer wall of which is slidably connected to the inner wall of the support column 6. The inner wall of the support column 6 is provided with a compression spring 16 and a third spring 18. The inner wall of the support column 6 is slidably connected to a trigger pin 17. The inside of the washer 1 is slidably connected to a detection rod 15.

[0029] Specifically, the warning pin 11 is fixed by engaging the trigger pin 17 with the warning pin 11. When the vibration amplitude of the equipment exceeds the preset elastic limit of the third spring 18, the trigger pin 17 will disengage from the warning pin 11 with violent shaking, and the compression spring 16 below the warning pin 11 will quickly reset and lift the warning pin 11. If fluid leakage occurs in the equipment, the leaking fluid will flow precisely into the third chute, and the fluid pressure will push the detection rod 15 outward to quickly report the leakage problem. The system can monitor equipment vibration and potential fluid leakage in real time, provide early warning of fault risks, provide reliable protection for the continuous and stable operation of the equipment, and greatly reduce downtime losses caused by sudden failures.

[0030] Reference Figure 2 The inner wall of the bushing 10 is provided with an oil groove, and the inner wall of the sleeve 9 is provided with an L-shaped groove. The surface of the limiting pin 8 is slidably connected in the L-shaped groove.

[0031] Specifically, when the positioning pin 7 is inserted into the sleeve 9 to fix the washer 1, the limiting pin 8 precisely enters the L-shaped groove and locks in place, thus achieving precise and stable fixation of the washer 1.

[0032] Reference Figure 4 The surface of washer 1 is provided with a piston cavity, the surface of the second spring 14 is slidably connected to the piston cavity, and the surface of piston 5 is slidably connected to the piston cavity.

[0033] Specifically, when the operating pressure increases, the pressure inside the piston chamber increases, lifting piston 5 and dispersing local stress.

[0034] Reference Figure 1 The surface of washer 1 is provided with a pressure balance groove, and the surface of washer 1 is provided with a first sliding groove. The surface of compensation ring 12 is fixedly connected to the first sliding groove.

[0035] Specifically, the pressure balancing tank can be filled with fluid, and the pressure is dispersed through fluid flow to achieve pressure balance.

[0036] Reference Figure 1 The surface of the support column 6 is provided with a second sliding groove, the surface of the trigger pin 17 is slidably connected in the second sliding groove, and the surface of the warning pin 11 is slidably connected in the second sliding groove.

[0037] Specifically, the second groove on the surface of the support column 6 provides a precise sliding track for the trigger pin 17 and the warning pin 11, which can strictly limit the movement direction of the two, prevent them from deviating or getting stuck, and ensure that the vibration detection function works stably.

[0038] Reference Figure 5 The inside of the washer 1 is provided with a third groove, and the surface of the detection rod 15 is slidably connected in the third groove.

[0039] Specifically, the detection rod 15 is made of elastic material to adapt to the pressure changes of the washer 1, so that the detection effect can operate normally.

[0040] Reference Figure 1 The surface of washer 1 has a tapered guide opening.

[0041] Specifically, the tapered guide opening on the surface of washer 1 can guide the bolt or corresponding component to be precisely aligned with the assembly position during installation, reducing installation deviation and improving assembly efficiency.

[0042] Working principle: When the stainless steel washer with positioning hole is in use, the positioning pin 7 is inserted into the sleeve 9, and the limiting pin 8 engages along the L-shaped groove to achieve precise fixation. The tapered guide port auxiliary bolt is fixed to the bushing 10. During the sealing stage, the oil groove grease inside the bushing 10 reduces wear and prevents leakage. The protrusion 2 forms a multi-point sealing adaptation scratch. The pressure balance groove balances the pressure through fluid flow. When the working conditions change, the support column 6 disperses the pressure. The piston 5, combined with the second spring 14, adjusts the sealing contact area. The compensation ring 12 compensates for the displacement of the sealing surface caused by vibration, thus achieving adaptive sealing.

[0043] During fault detection, when the vibration exceeds the limit, the trigger pin 17 disengages from the warning pin 11. Under the action of the compression spring 16, the warning pin 11 is pushed up. The leaking fluid pushes the elastic detection rod 15 in the third slide to push out and report the leakage problem. Finally, the positioning, sealing, adaptive adjustment and fault warning functions are realized through the cooperation of multiple structures.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
