Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing gaskets, specifically a sealing gasket for fluid machinery equipment. Background Technology
[0002] A gasket is a component used to fill the space between two objects, increase sealing, prevent leakage, and maintain system stability. It is typically placed between two flanges or other connecting parts and forms a sealing barrier by compression or tightening. It is indispensable in many industrial applications, especially where it is necessary to prevent fluid leakage or maintain system pressure.
[0003] Fluid machinery refers to mechanical devices used to handle fluid motion and energy conversion, including pumps, compressors, turbines, fans, jet engines, mixers, and agitators. Gaskets are indispensable components in fluid machinery to improve the sealing performance of the equipment and prevent leakage.
[0004] When installing gaskets in fluid machinery, multiple bolts are typically used to secure the gaskets. However, during operation, the drive end of the fluid machinery exerts a certain tensile force on the gaskets, causing the perforations in the gaskets to press against the bolts. Over time, this can lead to tearing between the perforations and bolts, resulting in gasket misalignment. Therefore, those skilled in the art have provided a gasket for fluid machinery to address the problems mentioned in the background section. Utility Model Content
[0005] The purpose of this invention is to provide a sealing gasket for fluid machinery equipment, which can solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing gasket for fluid machinery equipment, comprising a device body and a drive end mounted on the top of the device body, and further comprising: a gasket body disposed on the outside of the drive end, which improves the sealing performance of the device body; a mounting base plate disposed at the bottom of the gasket body; a mounting cylinder fixedly mounted on the outside of the mounting base plate; and a mounting cover disposed at the top of the mounting cylinder; an insertion mechanism for positioning and mounting the gasket body on the outside; and a fixing mechanism for buffering and assisting in resetting the gasket body, which is mounted between the mounting base plate and the mounting cover.
[0007] Preferably, the insertion mechanism includes an extension ring fixedly installed on the outside of the gasket body. The extension ring and the gasket body are made of the same material, and the thickness of the extension ring is greater than that of the gasket body. Multiple insert blocks are provided at equal intervals in a ring shape at the top and bottom of the extension ring. The insert blocks at the top of the extension ring are fixedly installed at the bottom of the mounting cover, and the insert blocks at the bottom of the extension ring are fixedly installed at the top of the mounting base plate. The top and bottom of the extension ring are provided with slots for the insert blocks to be inserted and positioned. The mounting cover and the mounting base plate are respectively fitted onto the top and bottom of the gasket body, and the insert blocks are inserted into the slots of the extension ring, increasing the contact surface with the gasket body and improving the firmness of the gasket body installation, thereby enhancing the durability of the gasket body.
[0008] Preferably, the gasket fixing mechanism includes two retaining rings symmetrically installed inside the extension ring. Multiple pressure posts distributed equidistantly in a ring are fixedly connected to the inner side of each retaining ring. The surface of the gasket body has an elongated groove for the pressure posts to be inserted and positioned. The elongated groove extends to the inner side of the gasket body, facilitating fluid retention on the gasket body. The bottom of the mounting cover and the top of the mounting base plate both have sliding cavities for the pressure posts to be slidably positioned. A spring is fixedly connected between the sliding cavity and the pressure post to hold it in place. When the gasket body is installed, the elasticity of the spring allows the pressure post to hold against the elongated groove of the gasket body, and the retaining rings can support the inner side of the extension ring, increasing the rebound force of the gasket body during use and thus improving the elasticity of the gasket body.
[0009] Preferably, the inserts on the mounting cover and the inserts on the mounting base are distributed in a cross-symmetrical manner to improve the stability of the insert installation.
[0010] Preferably, both the inner side of the slot and the outer side of the insert are inclined structures, which facilitates the insertion of the insert into the slot.
[0011] Preferably, the pressure column has a hollow top structure, and a guide column is provided on the inner side of the pressure column for limiting sliding. The guide column is fixedly installed on the inner side of the sliding cavity to prevent the pressure column from tilting.
[0012] Preferably, the outer diameter of the retaining ring is the same as the inner diameter of the extension ring, and is used to support the inner side of the extension ring.
[0013] Preferably, the bottom of the mounting cover is fixedly connected to a plug cylinder, and the top of the mounting cylinder is provided with an annular groove for the plug cylinder to be inserted into and limited, thereby improving the sealing performance between the mounting cover and the mounting cylinder.
[0014] Preferably, the end of the insert away from the mounting cover is made of rubber to facilitate insert installation.
[0015] Preferably, a bolt cylinder is fixedly installed on the outer side of the mounting cylinder. The outer side of the bolt cylinder has a prismatic structure, and the outer side of the bolt cylinder is movably sleeved on the outer sleeve of the bolt cylinder, which facilitates the quick installation of the mounting cover and the mounting cylinder onto the equipment body.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model uses an insertion mechanism to fit the mounting cover and mounting base plate onto the top and bottom of the gasket body, respectively, and inserts the insert block into the slot of the extension ring, increasing the contact surface with the gasket body and improving the firmness of the gasket body installation, thereby improving the durability of the gasket body.
[0018] 2. This utility model, through the fixed plate mechanism, can utilize the elasticity of the spring to make the pressure column abut against the long groove of the gasket body when installing the gasket body, and the retaining ring can support the inner side of the extension ring, thereby improving the rebound force of the gasket body during use and thus achieving the effect of improving the elasticity of the gasket body.

[0026] 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.
[0027] Example 1
[0028] Please see Figure 1 and Figure 2 The diagram shows a sealing gasket for fluid machinery, comprising a device body 1 and a drive end 2 mounted on top of the device body 1. It also includes: a gasket body 5 disposed on the outside of the drive end 2, which improves the sealing performance of the device body 1; a mounting base plate 6 at the bottom of the gasket body 5; a mounting cylinder 7 fixedly mounted on the outside of the mounting base plate 6; and a mounting cover 8 at the top of the mounting cylinder 7; an insertion mechanism 3 for positioning and mounting the gasket body 5 on the outside; and a fixing mechanism 4 for buffering and assisting in resetting the gasket body 5, which is installed between the mounting base plate 6 and the mounting cover 8.
[0029] Please see Figures 3-5 The insertion mechanism 3 shown in the figure includes an extension ring 301 fixedly installed on the outside of the gasket body 5. The extension ring 301 and the gasket body 5 are made of the same material. The thickness of the extension ring 301 is greater than that of the gasket body 5. Multiple insertion blocks 302 are provided at the top and bottom of the extension ring 301 in a ring and equidistant arrangement. The insertion blocks 302 at the top of the extension ring 301 are fixedly installed on the bottom of the mounting cover 8. The insertion blocks 302 at the bottom of the extension ring 301 are fixedly installed on the top of the mounting base plate 6. The top and bottom of the extension ring 301 are provided with slots 303 for the insertion blocks 302 to be limited and inserted.
[0030] The user will insert the gasket body 5 into the mounting cylinder 7 and insert the mounting cover 8 and the insert block 302 on the mounting base plate 6 into the slot 303 of the extension ring 301 to increase the contact surface for the gasket body 5 and improve the firmness of the installation. When the drive end 2 is running, the friction between the drive end 2 and the gasket body 5 is absorbed by the extension ring 301 and the insert block 302, which improves the stability of the gasket body 5 and enhances its durability.
[0031] Please see Figures 4-6The fixed plate mechanism 4 shown in the figure includes two retaining rings 401 symmetrically installed inside the extension ring 301. Multiple pressure columns 402 distributed in a ring are fixedly connected to the inner side of the retaining rings 401. The surface of the gasket body 5 is provided with a long groove for the pressure columns 402 to be inserted and limited. The long groove extends to the inner side of the gasket body 5 to facilitate fluid retention on the gasket body 5. The bottom of the mounting cover 8 and the top of the mounting base plate 6 are both provided with sliding cavities for the pressure columns 402 to be limited and slid. A spring 403 is fixedly connected between the sliding cavity and the pressure column 402 to hold the pressure column 402 in place.
[0032] When the user installs the gasket body 5, the pressure post 402 on the mounting base plate 6 and mounting cover 8 comes into contact with the gasket body 5. The spring force of the spring 403 causes the pressure post 402 to press against the long groove on the gasket body 5, and the retaining ring 401 can support the inner side of the extension ring 301, thereby increasing the rebound force of the gasket body 5 during use and improving the elasticity of the gasket body 5.
[0033] The working principle for improving the durability of the gasket body 5 is as follows: First, the user inserts the gasket body 5 into the mounting cylinder 7, and inserts the mounting cover 8 and the insert block 302 on the mounting base plate 6 into the slot 303 of the extension ring 301, increasing the contact surface for the gasket body 5 and improving the firmness of the installation. At the same time, the pressure post 402 on the mounting base plate 6 and the mounting cover 8 contacts the gasket body 5. The elastic force of the spring 403 makes the pressure post 402 press against the long groove on the gasket body 5, and the retaining ring 401 can support the inner side of the extension ring 301, improving the rebound force of the gasket body 5 during use. When the drive end 2 is running, the friction force generated between the drive end 2 and the gasket body 5 is absorbed by the extension ring 301 and the insert block 302, improving the stability of the gasket body 5 and preventing tearing. This achieves the effect of improving the durability of the gasket body 5 and facilitating installation and disassembly.
[0034] Example 2
[0035] Please see Figures 3-6 This embodiment further illustrates Example 1. In the figure, the insert 302 on the mounting cover 8 and the insert 302 on the mounting base plate 6 are symmetrically distributed to improve the firmness of the insert 302 installation. The inner side of the slot 303 and the outer side of the insert 302 are both inclined structures, which facilitates the insertion of the insert 302 into the slot 303. The pressure post 402 has a hollow top structure. The inner side of the pressure post 402 is limited by a guide post 9. The guide post 9 is fixedly installed on the inner side of the sliding cavity to prevent the pressure post 402 from tilting. The outer diameter of the retaining ring 401 is the same as the inner diameter of the extension ring 301, which is used to support the inner side of the extension ring 301.
[0036] In this embodiment, the cross-distributed inserts 302 can increase the thickness of the extension ring 301 and improve its toughness. The guide post 9 can support the inner side of the pressure post 402 and prevent the pressure post 402 from tilting when it moves.
[0037] Example 3
[0038] Please see Figures 1-5 This embodiment further illustrates other embodiments. In the figure, the bottom of the mounting cover 8 is fixedly connected to the insert 10. The top of the mounting cylinder 7 is provided with an annular groove for the insert 10 to be inserted and positioned, which improves the sealing performance between the mounting cover 8 and the mounting cylinder 7. The end of the insert 10 away from the mounting cover 8 is made of rubber, which facilitates the installation of the insert 10. A bolt cylinder 11 is fixedly installed on the outside of the mounting cylinder 7. The outside of the bolt cylinder 11 has a prismatic structure. The outside of the bolt cylinder 11 is movably sleeved on the sleeve 12 on the outside of the bolt cylinder 11, which facilitates the quick installation of the mounting cover 8 and the mounting cylinder 7 on the equipment body 1.
[0039] In this embodiment, the purpose is that when the mounting cover 8 is installed, the insert 10 is inserted into the annular groove on the mounting cylinder 7, and at the same time, the sleeve 12 is put on the bolt cylinder 11, so that the mounting cover 8 and the mounting cylinder 7 can be fixed to the equipment body 1 by bolts, which facilitates the installation and removal of the gasket body 5.
