Description

Technical Field

[0001] This utility model relates to the field of split mechanical seal technology, specifically, to a split mechanical seal. Background Technology

[0002] Split mechanical seals are a type of mechanical seal. The most significant feature of split mechanical seals is their split structure. Unlike traditional integral mechanical seals, they are designed to be split into two or more parts. This structure facilitates installation and disassembly, especially for large rotating equipment where integral sealing is difficult to install. Split mechanical seals are mainly composed of stationary ring assembly, rotating ring assembly, spring components, and sealing components. Sealing is achieved through the fit between the end faces of the stationary ring and the rotating ring.

[0003] In the existing technology, split mechanical seals are usually assembled by bolts. However, because the installation location of split mechanical seals is usually in a small space with many obstructions, it is not convenient to use tools to install or remove the bolts when assembling them by bolts, resulting in a long time consumption when assembling or disassembling split mechanical seals. Utility Model Content

[0004] This invention proposes a split mechanical seal to solve the problem that existing split mechanical seals, which are assembled with bolts, are not convenient for installation in small spaces or with many obstructions, resulting in long assembly or disassembly times.

[0005] The technical solution of this utility model is as follows: A split mechanical seal includes a body shaft, with a first housing and a second housing disposed on the outer side of the body shaft. It also includes an L-shaped splicing plate, a splicing seat, guide posts, a sliding plate, a positioning block, a first return spring, a mounting seat, a transmission seat, an adjusting rod, a mounting sleeve, and a spring-loaded actuating mechanism. Two L-shaped splicing plates are mounted on the outer side of the first housing, and two splicing seats are mounted on the outer side of the second housing. Multiple guide posts are installed inside the splicing seats, and a sliding plate is sleeved on each guide post, allowing the sliding plate to move along the guide post. The positioning block is mounted on... The first return spring is sleeved on the guide post and is mounted on the inner side of the sliding plate and moves synchronously with the sliding plate. The two ends of the first return spring are respectively connected to the splicing seat and the sliding plate. The mounting seat is mounted on the outer side of the sliding plate. A transmission seat is mounted on the outer side of the mounting seat through a connecting rod. The adjusting rod is inserted into the outer side of the splicing seat and can move inside the splicing seat. A mounting sleeve is installed on the lower side of the adjusting rod. Two sets of spring-loaded actuating mechanisms are provided on the outer side of the mounting sleeve. The spring-loaded actuating mechanisms are used to adjust the position of the transmission seat.

[0006] The spring-loaded actuation mechanism includes a mounting shell, a limiting rod, an actuation seat, and a second return spring. The mounting shell is installed on the outside of the mounting sleeve, the limiting rod is installed in the middle of the inner wall of the mounting shell, the actuation seat is sleeved on the limiting rod and can move along the limiting rod, and the second return spring is sleeved on the limiting rod. The two ends of the second return spring are respectively connected to the mounting shell and the actuation seat.

[0007] As a preferred embodiment of the split mechanical seal described in this utility model, in order to actuate the transmission seat through the actuating seat without affecting the normal movement of the actuating seat, the inner side of the actuating seat is shaped like a sloping triangle, and the transmission seat is shaped like a conical frustum.

[0008] In a preferred embodiment of the split mechanical seal described in this utility model, in order to achieve the insertion and positioning between the L-shaped splicing plate and the splicing seat, positioning slots are provided on the outer side of the L-shaped splicing plate and the inner side of the splicing seat, and the width of the positioning slots is adapted to the width of the positioning block.

[0009] In a preferred embodiment of the split mechanical seal described in this utility model, in order to limit the sliding of the sliding plate and ensure the stability of the sliding plate during sliding, limit slide rails are installed on both sides of the inner wall of the splicing seat, and the sliding plate is slidably connected to the limit slide rails.

[0010] In a preferred embodiment of the split mechanical seal described in this utility model, in order to detach the mounting sleeve from the transmission seat, a detachment slide is sleeved on the connecting rod, and the detachment slide can move along the connecting rod.

[0011] The working principle and beneficial effects of this utility model are as follows:

[0012] In this utility model, the positioning state of the positioning block on the L-shaped splicing plate and splicing seat is quickly adjusted by the cooperation between the mounting base, transmission base, adjusting rod, mounting sleeve and spring-loaded actuating mechanism. This allows the operator to adjust the positioning state of the positioning block according to the requirements. The operation is simple and the positioning state of the positioning block can be adjusted without the aid of tools, thereby enabling the rapid splicing or disassembly of the split mechanical seal.

[0013] By cooperating with the L-shaped splicing plate, splicing seat, guide post, sliding plate, positioning block and first return spring, the split mechanical seal can be quickly spliced ​​or disassembled, which speeds up the splicing or disassembly of the split mechanical seal, improves work efficiency, and can be adapted to different installation environments, thus increasing the application range of the split mechanical seal.

[0014] Compared to existing split mechanical seals, which use bolt assembly for splicing, making them inconvenient to operate in installation locations with limited space and many obstructions, resulting in long splicing or disassembly times, this split mechanical seal uses adjustable component splicing instead of bolt splicing. This enables rapid splicing or disassembly of the split mechanical seal, making it suitable for different installation environments, with a wider range of applications, convenient operation, and fast splicing or disassembly speed.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4As shown, this embodiment proposes a split mechanical seal, including a body shaft 1, a first housing 2 and a second housing 3 disposed on the outer side of the body shaft 1, and also includes an L-shaped splicing plate 4, a splicing seat 5, a guide post 6, a sliding plate 7, a positioning block 8, a first return spring 9, a mounting seat 10, a transmission seat 11, an adjusting rod 12, a mounting sleeve 13, and a spring-loaded actuating mechanism. Compared with the existing split mechanical seals, which use bolt assembly for splicing, making it inconvenient to operate in installation locations with limited space and many obstructions, resulting in long splicing or disassembly times, this embodiment addresses the problem by using the mounting seat 10, transmission seat 11, adjusting rod 12, mounting sleeve 13, and spring-loaded actuating mechanism... The coordinated operation enables rapid adjustment of the positioning status of the positioning block 8 relative to the L-shaped splicing plate 4 and the splicing seat 5. This allows operators to adjust the positioning status of the positioning block 8 according to their needs. The operation is simple and does not require tools to adjust the positioning status of the positioning block 8, thus enabling rapid assembly or disassembly of the split mechanical seal. Through the coordination between the L-shaped splicing plate 4, the splicing seat 5, the guide post 6, the sliding plate 7, the positioning block 8, and the first return spring 9, rapid assembly or disassembly of the split mechanical seal is achieved, accelerating the assembly or disassembly speed, improving work efficiency, and adapting to different installation environments, thus expanding the applicability of the split mechanical seal.

[0024] like Figure 1 and Figure 2 As shown, a first housing 2 and a second housing 3 are provided on the outer side of the body shaft 1. The interiors of the first housing 2 and the second housing 3 are provided with a stationary ring assembly 14, a moving ring assembly 15, a spring 16, and a seal 17. Two L-shaped splicing plates 4 are installed on the outer side of the first housing 2, and two splicing seats 5 are installed on the outer side of the second housing 3, as shown... Figure 3 As shown, multiple guide posts 6 are installed inside the splicing base 5, and sliding plates 7 are sleeved on the guide posts 6. Limit rails are installed on both sides of the inner wall of the splicing base 5. The sliding plates 7 are slidably connected to the limit rails, which limit the sliding of the plates 7, thus ensuring the stability of the sliding plates 7 during sliding. Limit baffles are installed on the inner side of the limit rails, and the outer side of the limit baffles is connected to the inner wall of the splicing base 5. The limit baffles block and limit the sliding of the plates 7, thus preventing the plates 7 from derailing. Positioning block 8 is installed on the inner side of sliding plate 7. Positioning slots are provided on the outer side of L-shaped splicing plate 4 and the inner side of splicing base 5. The width of the positioning slots is adapted to the width of positioning block 8. Positioning block 8 can be inserted into the interior of L-shaped splicing plate 4 and splicing base 5 through the positioning slots, thereby realizing the insertion and positioning of L-shaped splicing plate 4 and splicing base 5. First return spring 9 is sleeved on guide post 6. The two ends of first return spring 9 are respectively connected to splicing base 5 and sliding plate 7. Mounting base 10 is installed on the outer side of sliding plate 7, such as Figure 4As shown, a transmission seat 11 is mounted on the outer side of the mounting base 10 via a connecting rod. A release slide is sleeved on the connecting rod, allowing the release slide to move along the connecting rod. The actuating seat 103 inside the spring-loaded actuating mechanism can detach from the transmission seat 11 via the release slide. An adjusting rod 12 is inserted into the outer side of the splicing base 5. A mounting sleeve 13 is mounted on the lower side of the adjusting rod 12. Two sets of spring-loaded actuating mechanisms are provided on the outer side of the mounting sleeve 13. Each spring-loaded actuating mechanism includes a mounting shell 101, a limiting rod 102, an actuating seat 103, and a second return spring 104. The mounting shell 101 is mounted on the outer side of the mounting sleeve 13, and the limiting rod 102 is mounted on the outer side of the mounting base 10. In the middle of the inner wall of the housing 101, the actuating seat 103 is sleeved on the limiting rod 102, and the second return spring 104 is sleeved on the limiting rod 102. The two ends of the second return spring 104 are connected to the housing 101 and the actuating seat 103 respectively. The inner side of the actuating seat 103 is shaped like a sloping triangle, and the transmission seat 11 is shaped like a conical frustum. The special shape design of the actuating seat 103 and the transmission seat 11 allows the actuating seat 103 to move towards the square of the housing 101 when it contacts the outer side of the transmission seat 11. When the actuating seat 103 is inside the transmission seat 11, the actuating seat 103 can actuate the transmission seat 11.

[0025] Working principle:

[0026] When the split mechanical seal needs to be assembled, the operator gradually installs the stationary ring assembly 14, the rotating ring assembly 15, the spring 16, and the seal 17 on the outside of the shaft 1. Then, the first housing 2 and the second housing 3 are fitted onto the outside of the stationary ring assembly 14, the rotating ring assembly 15, the spring 16, and the seal 17. During the fitting process, the operator pushes the mounting sleeve 13 inward using the adjusting rod 12. The mounting sleeve 13 is fitted onto the transmission seat 11. During the movement of the mounting sleeve 13, the transmission seat 1... 03 contacts the outer side of the transmission seat 11. The transmission seat 11 pushes the actuating seat 103 to move outward along the limiting rod 102. The actuating seat 103 compresses the second return spring 104. When the actuating seat 103 moves to the inner side of the transmission seat 11, it moves inward under the action of the second return spring 104, so that the actuating seat 103 can actuate the transmission seat 11. Then, the operator pulls the adjusting rod 12 to move outward. The adjusting rod 12 passes through the mounting sleeve 13 and the actuating seat 103. Pull the transmission seat 11 outward. The transmission seat 11, through the connecting rod and mounting seat 10, drives the sliding plate 7 to move outward along the guide post 6. The sliding plate 7 compresses the first return spring 9, and the sliding plate 7 drives the positioning block 8 to move outward. Then, after the first housing 2 and the second housing 3 are docked, release the adjusting rod 12. Under the action of the first return spring 9, the sliding plate 7 drives the positioning block 8 to insert into the interior of the L-shaped splicing plate 4 and the splicing seat 5, realizing the splicing and installation of the split mechanical seal. After the splicing is completed, The operator pushes the adjusting rod 12 inward again, which moves the mounting sleeve 13 and the actuating seat 103 inward, so that the actuating seat 103 moves to the inside of the disengaged slide. Then the operator pulls the adjusting rod 12 outward, which moves the actuating seat 103 outward, so that the disengaged slide contacts the transmission seat 11. At this time, the actuating seat 103 disengages from the transmission seat 11 with the cooperation of the disengaged slide, so that the split mechanical seal is not affected by the adjusting rod 12 and the spring-loaded actuating mechanism after splicing.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
