Description

Technical Field

[0001] This utility model relates to the field of six-way valve technology, specifically a novel integrated six-way valve structure for gas turbine lubricating oil. Background Technology

[0002] When a gas turbine is running, the lubrication system needs to continuously provide lubrication and cooling for core components such as rotors and bearings. As a key component for controlling the flow and direction of the system, the sealing performance of the valve island body and the connector of the six-way valve directly affects the stability of the system.

[0003] However, traditional six-way valves for gas turbine lubricating oil mostly use a single planar sealing structure for the valve island body and connector, relying on ordinary sealing rings to achieve sealing. This makes it difficult to adapt to the slight surface deviations between components, resulting in limited sealing effect. At the same time, the traditional structure lacks a compression force adjustment mechanism, and the sealing ring is prone to gaps due to fatigue deformation after long-term use, leading to sealing failure. Furthermore, the lack of an isolation and protection structure allows high-pressure lubricating oil to directly impact the sealing ring, accelerating its aging and damage, and further shortening the service life of the sealing components. Therefore, a new integrated six-way valve structure for gas turbine lubricating oil is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a novel integrated six-way valve structure for gas turbine lubricating oil, in order to solve the problems mentioned in the background art, such as the single sealing method of the valve island body and the connector of the traditional six-way valve for gas turbine lubricating oil and the lack of a squeezing force adjustment mechanism.

[0014] 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.

[0015] Please see Figure 1 - Figure 3 The present invention provides a novel integrated six-way valve structure for gas turbine lubricating oil, including a valve island body 1, the inner wall of which is provided with multiple connectors 2, and also includes; A sealing assembly is disposed between the valve island body 1 and the connector 2, and is used to perform a curved seal on the gap between the valve island body 1 and the connector 2. An adjustment component is provided on the surface of the connector 2 for flexibly adjusting the squeezing force between the valve island body 1 and the connector 2; An isolation component is disposed between the valve island body 1 and the connector 2 to provide secondary isolation between the valve island body 1 and the connector 2.

[0016] Furthermore, the sealing assembly includes multiple double-convex sealing rings 301, which are disposed between the connector 2 and the valve island body 1. The inner wall of the valve island body 1 has a connecting groove 302, and one end of the connector 2 has a limiting groove 303. The two ends of the double-convex sealing rings 301 are respectively matched with the inner walls of the connecting groove 302 and the limiting groove 303. Through the sealing assembly, the limiting groove 303 is disposed between the valve island body 1 and the connector 2, so that when the connector 2 is connected to the valve island body 1, the double-convex sealing rings 301 are squeezed, thereby sealing the connector 2 and the valve island body 1 through the double-convex sealing rings 301. At the same time, the upper and lower ends of the double-convex sealing rings 301 are both convex. The double-convex sealing rings 301 with both ends protruding cooperate with the connecting groove 302 and the limiting groove 303 to facilitate curved surface sealing between the valve island body 1 and the connector 2, thereby improving the sealing effect.

[0017] Furthermore, the adjusting component includes multiple hexagonal threaded rings 401, which are disposed on the surface of the connector 2. The surface of the connector 2 is provided with threads 402, which are threadedly connected to the hexagonal threaded rings 401. A wear-resistant ring 403 is fitted onto the surface of the connector 2. The lower end of the wear-resistant ring 403 abuts against the top surface of the valve island body 1, and the upper end of the wear-resistant ring 403 abuts against the lower end of the hexagonal threaded ring 401. Through the adjusting component, rotating the hexagonal threaded ring 401 allows for flexible adjustment of the compression force between the valve island body 1 and the connector 2, thereby preventing the double-convex sealing ring 301f from developing gaps due to fatigue and affecting the seal. For sealing effect, rotating the hexagonal threaded ring 401 clockwise allows the connector 2 to continuously pre-tighten the double convex sealing ring 301, thus ensuring that the double convex sealing ring 301 maintains a good sealing effect. The wear-resistant ring 403 increases the friction between the hexagonal threaded ring 401 and the valve island body 1, preventing the hexagonal threaded ring 401 from rotating on its own and affecting the sealing effect. At the same time, the wear-resistant ring 403 itself has elastic properties and deforms after being compressed. When the wear-resistant ring 403 recovers its elasticity, it can continuously push the hexagonal threaded ring 401 to the connector 2, thus maintaining a good sealing effect between the connector 2 and the valve island body 1.

[0018] Furthermore, the isolation assembly includes an isolation plate 501, which is slidably connected to the inner wall of the valve island body 1. Multiple compression springs 502 are fixedly connected to the bottom surface of the isolation plate 501, with the lower ends of each compression spring 502 fixedly connected to the inner wall of the valve island body 1. Multiple sealing gaskets 503 are fixedly connected to the top surface of the isolation plate 501, with the upper ends of the sealing gaskets 503 abutting against the lower end of the connector 2. Through this isolation assembly, the compression springs 502 push the isolation plate 501, thereby causing the top surface of the isolation plate 501 to... The surface abuts against the lower end of multiple connectors 2, thereby facilitating secondary isolation between the lubricating oil and the gap between the valve island body 1 and the connector 2. This reduces the impact on the double convex seal 301 when the lubricating oil pressure directly contacts the double convex seal 301, ensuring that the double convex seal 301 maintains a good sealing effect. At the same time, through the elastic properties of the compression spring 502, it is easy for the double convex seal 301 to maintain a good isolation effect between the isolation plate 501 and the connector 2 after fatigue and continuous pre-tightening.

[0019] Working principle: During use, the limiting groove 303 is set between the valve island body 1 and the connector 2 through the sealing component. When the connector 2 is connected to the valve island body 1, the double convex sealing ring 301 is squeezed, thereby sealing the connection between the connector 2 and the valve island body 1 through the double convex sealing ring 301. At the same time, the upper and lower ends of the double convex sealing ring 301 are both convex. The double convex sealing ring 301 with both convex ends cooperates with the connecting groove 302 and the limiting groove 303 to facilitate curved surface sealing between the valve island body 1 and the connector 2, thereby improving the sealing effect.

[0020] Secondly, by adjusting the components, the squeezing force between the valve island body 1 and the connector 2 can be flexibly adjusted by rotating the hexagonal threaded ring 401, thereby avoiding the gap caused by fatigue of the double convex sealing ring 301f, which affects the sealing effect. Rotating the hexagonal threaded ring 401 clockwise will allow the connector 2 to continuously pre-tighten the double convex sealing ring 301, thereby ensuring that the double convex sealing ring 301 maintains a good sealing effect.

[0021] Furthermore, the isolation component allows the isolation plate 501 to be pushed by the compression spring 502, causing the top surface of the isolation plate 501 to abut against the lower ends of the multiple connectors 2. This facilitates secondary isolation between the lubricating oil and the gap between the valve island body 1 and the connectors 2, thereby reducing the impact on the double convex seal 301 when the lubricating oil pressure comes into direct contact with it, thus ensuring that the double convex seal 301 maintains a good sealing effect.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
