[0038] Secondly, the present invention is described in detail with reference to the schematic diagrams.

[0039] Example 1

[0040] Reference Figure 1 - Figure 5 This first embodiment of the invention provides a valve protection device. The device includes an installation assembly 100, comprising a receiving member 101, a moving member 102, an auxiliary member 103, and a locking member 104. The moving member 102 is disposed on the receiving member 101, the auxiliary member 103 is disposed on the moving member 102, and the locking member 104 is disposed on the auxiliary member 103. Through the interaction between the receiving member 101, the moving member 102, the auxiliary member 103, and the locking member 104, the initial process of installing the device on the valve is simplified. The assembly is easy to operate, making installation faster and more accurate, and providing a good foundation for subsequent reinforcement and diversion measures.

[0041] Specifically, the receiving component 101 includes a lower valve body 101a, a sealing point 101b, a connecting pipe 101c, an actuator 101d, and a mounting groove 101e. The sealing point 101b is located on the lower valve body 101a, the connecting pipe 101c is located on the sealing point 101b, and the actuator 101d is located on the connecting pipe 101c. The lower valve body 101a, the sealing point 101b, the connecting pipe 101c, and the actuator 101d constitute the structural components of the valve. The sealing point 101b is self-sealing, and the static sealing position such as the packing is also the location where leakage may occur during valve use. The actuator 101d is susceptible to high-temperature steam leakage from the sealing point 101b. If the valve actuator 101d is burned out, it will be rendered unusable, causing the valve in a critical part to be uncontrollable. This will drastically reduce the safety performance of the equipment system, making it impossible to guarantee safety. The mounting groove 101e is set on the connecting pipe 101c. The mounting groove 101e is located on the connecting pipe 101c between the actuator 101d and the seal 101b. Two "+" structures are set on both sides of the connecting pipe 101c, and the "|" part is longer than the "I" part. This makes it easier for other objects to initially enter the mounting groove 101e. When the "I" part enters the mounting groove 101e, it can improve the stability of the object after it enters.

[0042] Furthermore, the movable component 102 includes an adapter post 102a, a mounting block 102b, a disassembly / assembly groove 102c, and a disassembly / assembly post 102d. The adapter post 102a is disposed on the mounting groove 101e, and the number of adapter posts 102a is the same as the number of mounting grooves 101e. The adapter post 102a is movably connected to the mounting groove 101e. The adapter post 102a is composed of a rectangular block with short rectangular blocks connected to both sides. The adapter post 102a can be embedded into the mounting groove 101e to achieve the function of being installed onto the connecting pipe 101c. The mounting block 102b is disposed on the adapter post 102a and is movably connected to the adapter post 102a. The mounting block 102b is composed of two semi-circular rings. The mounting block 102b can... To match the connecting pipe 101c, the disassembly groove 102c is set on the mounting block 102b. The disassembly groove 102c is an "L" structure, with extended grooves on both sides of the "one" part, forming a cross structure. This allows it to connect with the adapter post 102a and improves the stability of the object installed in the disassembly groove 102c. The disassembly post 102d is set on the disassembly groove 102c and is embedded in the disassembly groove 102c. The disassembly post 102d is fixedly connected to the adapter post 102a. This allows the mounting block 102b to be stably and conveniently disassembled and installed onto the connecting pipe 101c by the disassembly post 102d and the adapter post 102a.

[0043] Furthermore, the auxiliary component 103 includes a first pushing groove 103a, a second pushing groove 103b, a first extension groove 103c, a second extension groove 103d, and a double-sided groove 103e. The first pushing groove 103a and the second pushing groove 103b are disposed on the mounting block 102b. The first pushing groove 103a and the second pushing groove 103b are respectively formed on two mounting blocks 102b. The first pushing groove 103a and the second pushing groove 103b are two "7" structures of different heights and the two slots interlock. Each mounting block 102b has a first pushing groove 103a and a second pushing groove 103b on both sides, which allows the two mounting blocks 102b to interlock and splice, improving the stability of the mounting block 102b installation. The first extension groove 103a... 3c is set on the first pushing groove 103a. The first extension groove 103c is opened on the first pushing groove 103a and is connected to the first pushing groove 103a. The first extension groove 103c is composed of horizontal grooves and arc grooves on both sides. The second extension groove 103d is set on the second pushing groove 103b and is connected to the second pushing groove 103b. The second extension groove 103d is the same as the first extension groove 103c, but their heights are different. The double-sided groove 103e is set on the mounting block 102b and is opened on the mounting block 102b. It is located in the middle of the first extension groove 103c and the second extension groove 103d. The auxiliary parts 103 are all for providing a place for subsequent object movement.

[0044] Furthermore, the fastening element 104 includes a pushing block 104a, an upper post 104b, a connecting post 104c, a spring arc plate 104d, a rotating post 104e, and a positioning post 104f. The pushing block 104a is disposed on the first pushing groove 103a and is movably connected to the first pushing groove 103a and the second pushing groove 103b. It also moves within the first extension groove 103c and the second extension groove 103d respectively. A pushing block 104a is provided on both sides of the first extension groove 103c and the second extension groove 103d. The push block 104a, located on one side of the mounting block 102b, moves into the groove of the other mounting block 102b for easy insertion. The upper post 104b and connecting post 104c are mounted on the push block 104a. The upper post 104b is fixedly connected to the push block 104a and is positioned on one side of the push block 104a. This allows the movement of the push block 104a to move the upper post 104b. When the two mounting blocks 102b are fully inserted, the push block 104a can move along with the upper post. 104b moves to the notch left after the mounting block 102b has been fitted with a matching groove, serving as a positioning element after the push block 104a moves. Connecting post 104c is movably connected to the push block 104a. The number of connecting posts 104c is the same as the number of push posts. Connecting posts 104c have a certain length on either the first extension groove 103c or the second extension groove 103d. Spring arc plate 104d is disposed on the connecting post 104c and is movably connected to it. The spring arc plate 104d is formed by connecting two connecting posts. The plate with a certain curvature formed by the column 104c is fixedly connected to the spring on the outside. One side of the spring is fixedly connected to the double-sided groove 103e. The two sides of the spring arc plate 104d and the push block 104a are connected to the two sides of the connecting column 104c. In this way, when one side of the connecting column 104c is pushed, the other side will also be pushed. When the spring arc plate 104d is installed with the mounting block 102b, it will be squeezed and moved to the first extension groove 103c or the second extension groove 103d, which will cause the push block 104a to move as well.

[0045] The rotating column 104e and the positioning column 104f are disposed on the connecting column 104c. The first extension groove 103c on one side of the mounting block 102b has two rotating columns 104e. The connection of one rotating column 104e makes one side of the connecting column 104c and the push block 104a rotatably connected, and the connection of the other rotating column 104e makes the other side of the connecting column 104c rotatably connected to the spring arc plate 104d. The positioning column 104f is fixedly connected to the first extension groove 103c or the second extension groove 103d and is located in the middle of the connecting column 104c. In this position, the pushing blocks 104a and the spring arc plate 104d on both sides of the connecting column 104c move in opposite directions. This makes it easy for the spring arc plate 104d to be pushed towards the double-sided groove 103e when the two mounting blocks 102b are connected. When there is no pushing force, the spring arc plate 104d will return to its original shape under the reverse action of the spring on its own, which is convenient for reuse next time. Since the positions of the pushing blocks 104a and the mounting positions of the adapter column 102a are presented on four surfaces, it is convenient to further strengthen the installation stability of the mounting blocks 102b.

[0046] During operation, the adapter column 102a and the disassembly column 102d are first moved and embedded into the mounting slot 101e. This causes the adapter column 102a to first position between the actuator 101d and the seal 101b. Then, the movable mounting block 102b is installed onto the disassembly column 102d through the disassembly slot 102c, allowing the mounting block 102b to be installed in the corresponding position. Alternatively, the mounting block 102b can be used to move and embed the adapter column 102a and the disassembly column 102d into the mounting slot 101e to complete the installation. In this case, the two mounting blocks 102b will move towards each other. The movement causes the spring arc plate 104d to move on the first extension groove 103c and the second extension groove 103d, so that the spring arc plate 104d moves into the mounting block 102b. This causes the pushing block 104a in one mounting block 102b to move with the upper side post 104b into the groove in another mounting block 102b under the reverse push of the connecting post 104c, thus fixing the installation position of the mounting block 102b. When the embedded installation is released, the two mounting blocks 102b can move towards each other to complete the disassembly, which also facilitates the replacement operation.

[0047] Example 2

[0048] Reference Figure 1 - Figure 7This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the device includes a reinforcement component 200, which includes a component 201 and a clamping component 202. The component 201 is disposed on the movable component 102, and the clamping component 202 is disposed on the component 201. The interaction between the component 201 and the clamping component 202 provides a stable foundation and a convenient replacement method for subsequent operations, ensuring the replacement of the valve protection device under high temperature and high pressure environments. The multi-module design facilitates rapid replacement for damage at any location.

[0049] Specifically, component 201 includes a follower post 201a, an upper ring block 201b, a lower ring block 201c, and an observation window 201d. The follower post 201a is mounted on the disassembly / assembly post 102d and is fixedly connected to it, located below the disassembly / assembly post 102d. The upper ring block 201b is mounted on the follower post 201a and is fixedly connected to it. The upper ring block 201b is a semi-circular ring structure with two components, moving with the disassembly / assembly post 102d. The lower ring block 201c is mounted on the upper ring block 201b. 01c is fixedly connected to the upper ring block 201b. The lower ring block 201c has the same number of structures as the upper ring block 201b, and a groove of a certain width is provided between the upper ring block 201b and the lower ring block 201c to allow objects to be placed in it. The upper ring block 201b and the lower ring block 201c are spliced ​​and wrapped around the sealing part 101b, so that the steam leaking from the sealing part 101b is on the lower ring block 201c. The observation window 201d is set on the lower ring block 201c, which is convenient for observing the operation of the valve. The observation window 201d can be set to be transparent for easy observation.

[0050] Furthermore, the clamping member 202 includes a bearing groove 202a, a lower arc-shaped column 202b, a spring piece 202c, and an upper arc-shaped column 202d. The bearing groove 202a is disposed on the upper ring block 201b, and is located on both sides of the upper ring block 201b at different positions, which facilitates the placement of objects of different heights within it. The lower arc-shaped column 202b is disposed on the bearing groove 202a and is movably connected to the bearing groove 202a. The lower arc-shaped column 202b is disposed on one side of the upper ring block 201b, and one side of the upper ring block 201b is an arc surface, which facilitates contact as the upper ring block 201b moves. The spring piece 202c is disposed on the lower arc-shaped column 202b, and one side of the spring piece 202c is fixed. The upper arc column 202d is connected to the lower arc column 202b, and the spring piece 202c is in a "Z" shape, which is suitable for connecting objects of different heights and also has a certain tensile displacement function. The upper arc column 202d is set on the spring piece 202c and is fixedly connected to the spring piece 202c, forming a structure with a height difference with the lower arc column 202b. The lower arc column 202b is also movably connected to the bearing groove 202a. As the upper ring block 201b and the lower ring block 201c are installed, the upper arc column 202d and the lower arc column 202b will move into the bearing groove 202a, and the spring piece 202c will also be stretched, so that the upper arc column 202d and the lower arc column 202b contact the valve. When the movement is released, the upper arc column 202d and the lower arc column 202b will return to their original shape under the action of the spring piece 202c.

[0051] The remaining structure is the same as that in Example 1.

[0052] Operation process: When the follower column 201a, along with the upper ring block 201b and lower ring block 201c, is installed along with the disassembly and assembly column 102d, the lower arc column 202b and upper arc column 202d on the upper ring column will adhere to the valve body under the action of the spring piece 202c. When the installation is not removed, they will not move in the opposite direction, thus strengthening the stability under the mounting block 102b. It is also a multi-module design that facilitates disassembly and replacement.

[0053] Example 3

[0054] Reference Figure 1 - Figure 10This is the third embodiment of the present invention, which differs from the second embodiment in that: the device includes a diversion assembly 300, including a rotating member 301, an adjusting member 302, and a dispersing member 303. The rotating member 301 and the adjusting member 302 are disposed on the component 201, and the dispersing member 303 is disposed on the adjusting member 302. Through the interaction between the rotating member 301, the adjusting member 302, and the dispersing member 303, and in conjunction with the reinforcement assembly 200, even if leakage occurs at the static sealing position of the valve, the steam can be effectively dispersed. This not only reduces the direct damage to the valve actuator 101d, but also avoids a larger-scale system runaway caused by the damage to the actuator 101d.

[0055] Specifically, the rotating component 301 includes a rotating handle 301a, an eccentric disk 301b, and a push plate 301c. The rotating handle 301a is mounted on the upper ring block 201b and is rotatably connected to the upper ring block 201b. The rotating handle 301a passes through the upper ring block 201b and can rotate on the outer surface of the upper ring block 201b. The eccentric disk 301b is mounted on the rotating handle 301a and is fixedly connected to the rotating handle 301a. The disc 301b is located at an eccentric position on the rotating handle 301a, which allows the eccentric disc 301b to move at a certain distance as the rotating handle 301a rotates. The push plate 301c is set on the eccentric disc 301b and is fixedly connected to the eccentric disc 301b. The rotation of the eccentric disc 301b drives the push plate 301c to rotate, and the push plate 301c has a certain length, which allows the rotating handle 301a to achieve a certain distance difference when rotating.

[0056] Furthermore, the adjusting component 302 includes an upper adjusting groove 302a, an upper adjusting block 302b, a lower adjusting groove 302c, a lower adjusting block 302d, and a diverting block 302e. The upper adjusting groove 302a is disposed on the upper ring block 201b, and is formed on both sides of the upper ring block 201b. The upper adjusting block 302b is disposed on the upper adjusting groove 302a and is movably connected to the upper adjusting groove 302a. The upper adjusting block 302b consists of a spring and a connecting block, allowing the connecting block to move flexibly under the action of the spring. The lower adjusting groove 302c is located on the lower ring block 201c, with openings on both sides of the lower ring block 201c. The lower adjusting block 302d is located on the lower adjusting groove 302c and is movably connected to the lower adjusting groove 302c. The lower adjusting block 302d consists of a spring and a connecting block. The connecting block, similar in composition to the upper adjusting block 302b, also possesses a certain degree of mobility. The diverting block 302e is positioned on the upper ring block 201b and is movably connected in the slot between the upper ring block 201b and the lower ring block 201c. The diverting block 302e has a certain upward inclination and is composed of a semi-circular structure. The range of the diverting block 302e is larger than that of the actuator 101d, which facilitates the coverage of a certain area of ​​the actuator 101d. The cover facilitates subsequent protection. It is installed simultaneously with the upper ring block 201b and the lower ring block 201c. The rotating handle 301a is positioned in the middle of the diverter block 302e. As the rotating handle 301a rotates, it drives the eccentric disk 301b and the push plate 301c to move. This causes the push plate 301c to contact one side of the diverter block 302e and press it down, allowing the diverter block 302e to be adjusted to a certain extent, thus achieving operational adjustability.

[0057] Furthermore, the dispersing component 303 includes a lower partition groove 303a, an upper partition groove 303b, a support block 303c, a first diverting groove 303d, a second diverting groove 303e, and a third diverting groove 303f. The lower partition groove 303a, upper partition groove 303b, support block 303c, first diverting groove 303d, second diverting groove 303e, and third diverting groove 303f are disposed on the diverting block 302e. The lower partition groove 303a is formed on the diverting block 302e, and the lower part of the diverting block 302e forms several fan-shaped blocks with a certain spacing. The upper partition groove 303a... 3b is located in the middle of the diversion block 302e, and is positioned slightly above the lower partition groove 303a with a certain spacing and staggered arrangement. The upper partition groove 303b is wider than the lower partition groove 303a. The upper partition groove 303b causes the diversion block 302e to form several fan-shaped blocks with a certain spacing. The support block 303c is located inside the diversion block 302e, between the fan-shaped blocks left after the lower partition groove 303a and the upper partition groove 303b are opened, and plays a supporting and blocking role for certain objects. The first diversion groove 303d, the second diversion groove 303e, and the third diversion groove 303d are also present. All 03f are located on the innermost side of the diversion block 302e and run through the entire diversion block 302e. The first diversion groove 303d is closest to the inner side of the diversion block 302e and there is a certain gap between them. This allows the corresponding position on the outer side of the diversion block 302e to have a groove to facilitate steam flow. The second diversion groove 303e is opened on one side of the first diversion groove 303d and is composed of an annular groove and a fan-shaped groove. The fan-shaped block left after the lower partition groove 303a corresponding to the fan-shaped groove is opened leaves a certain rectangular groove on the outer side of the diversion block 302e so that steam can pass through. Steam flows out through the second diversion channel 303e. The third diversion channel 303f is opened between the two fan-shaped slots of the two second diversion channels 303e. The third diversion channel 303f corresponds to the fan-shaped block left after the upper partition channel 303b is opened, so that steam can flow out through the third diversion channel 303f. The three diversion channels are in different positions, have different opening sizes, and have different flow paths, which can greatly disperse the leaked steam. As the diversion block 302e is adjusted by the push plate 301c, the flow direction of the diverted steam is different, reducing the direct damage to the valve actuator 101d.

[0058] The remaining structure is the same as that in Example 2.

[0059] Operating steps: The gas leaking from the seal 101b concentrates and impacts the actuator 101d upwards. The steam is effectively dispersed by the first diversion groove 303d, the second diversion groove 303e, and the third diversion groove 303f opened on the diversion block 302e. The different outlet positions of the three diversion grooves prevent the steam from directly impacting the actuator 101d. The diversion block 302e can disperse the steam to a range outside the actuator 101d. In addition, by rotating the handle 301a and its push plate 301c to adjust the angle of the diversion plate, it can be adjusted at any time according to the position of the steam, increasing the operability and adjustability.
