Abstract
Description
Technical Field
[0001] The utility model relates to the field of semiconductor processing, in particular to a water leakage prevention mechanism. Background Art
[0002] In modern industry and life, the sealing performance and water leakage prevention ability of pipeline connection systems are important factors affecting the safety and reliability of the systems. Especially in liquid transportation systems, the sealing performance at pipeline joints is directly related to the normal operation and maintenance cost of the systems. Traditional pipeline connection methods mainly rely on clamps and sealing rings to achieve sealing. However, during long-term use, due to factors such as material aging, environmental changes, and mechanical vibrations, the sealing rings may age, deform, or be damaged, resulting in leakage at pipeline joints.
[0003] In the prior art, to solve the problem of water leakage at pipeline joints, methods such as adding sealing rings at the joints or using higher-strength clamps are usually adopted. However, these methods still have certain limitations when facing long-term use and complex working conditions. For example, the material selection and installation method of the sealing rings have a great impact on the sealing effect, and in environments with high pressure, high temperature, or corrosive media, the performance of traditional sealing materials may significantly decline, resulting in sealing failure.
[0004] In addition, traditional water leakage prevention designs mainly focus on single sealing structures and lack multiple protection mechanisms. Once the primary seal fails, it often leads to relatively serious water leakage problems, increasing the maintenance difficulty and cost of the system. Therefore, it is particularly important to develop a water leakage prevention mechanism with multiple protection functions that can provide secondary protection when the primary seal fails. Summary of the Invention
[0005] (1) Technical Problems to be Solved
[0006] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a water leakage prevention mechanism, which solves the problems existing in the prior art. By designing an overflow groove and inner and outer overflow rings between the lower joint and the upper joint, a multiple protection structure is formed, effectively solving the water leakage problem existing in traditional pipeline connection methods. This design not only improves the sealing performance at pipeline joints but also, when the primary seal fails, through the design of the overflow groove and the overflow ring, guides the seepage water to flow back, preventing the spread of water leakage and ensuring the stable operation of the system.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1 - 5 Drawings of the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0025] A leak - prevention mechanism includes an inlet hose 1. The upper end of the inlet hose 1 is provided with an outlet hose 2. It is characterized in that a lower joint 3 is sleeved inside the inlet hose 1, a lower clamp 4 is fixed outside the joint of the inlet hose 1 and the lower joint 3, an upper joint 5 fixed by bolts is provided at the upper end of the lower joint 3, an outlet hose 1 is sleeved outside the upper joint 5, and an upper clamp 6 is fixed outside the joint of the outlet hose 2 and the upper joint 5;
[0026] Among them, the inlet hose 1 is the inlet part of the entire anti-leakage mechanism, used to guide the liquid into the system. The outlet hose 2 is the outlet part of the anti-leakage mechanism, used to guide the liquid out of the system, and cooperate with the upper joint (5) to form a seal at the outlet. The lower joint 3 is a cylinder with a flange, internally sleeved in the inlet hose 1, and its upper end is fixed to the upper joint 5 by bolts. The lower joint 3 plays a role in connecting the inlet hose 1 and the upper joint 5, forming a stable connection structure, and providing secondary protection through the designed overflow groove 32 to prevent leakage. The lower clamp 4 is fixed on the outside of the joint between the inlet hose 1 and the lower joint 3. The lower clamp 4 is used to fasten the inlet hose and the lower joint to ensure a tight connection between them and prevent liquid from leaking from the joint. The upper joint 5 is fixed to the upper end of the lower joint 3 by bolts and is externally sleeved with the outlet hose 2. The upper joint 5 is used to connect the lower joint and the outlet hose to form a seal at the outlet part and provides a stable connection through bolt fixation. The upper clamp 6 is fixed on the outside of the joint between the outlet hose 2 and the upper joint 5. The upper clamp 6 is used to fasten the outlet hose 2 and the upper joint 5 to ensure a tight connection between them and prevent liquid from leaking from the joint.
[0027] The lower joint 3 is a cylinder with a flange as a whole. The lower end of the lower joint 3 is the first clamping part 31, and an overflow groove 32 is provided at the upper end of the lower joint 3. The lower joint 3 is a cylinder with a flange as a whole. As an intermediate component connecting the inlet hose 1 and the upper joint 5, the lower joint 3 provides a stable mechanical connection and a primary seal. The lower end of the lower joint 3 is designed as the first clamping part 31. The first clamping part 31 is used to clamp with the inlet hose 1 to ensure a tight connection between the lower joint 3 and the inlet hose 1. Through the design of the clamping part, the sealing performance between the joint and the hose is ensured, and liquid leakage from the joint is prevented. An overflow groove 32 is provided at the upper end of the joint 3. The overflow groove 32 is used to collect the liquid leaking from the primary seal (i.e., the connection between the lower joint and the inlet hose). Through the designed shape and position of the overflow groove, the leaking liquid is guided back to prevent liquid overflow. In the case of the failure of the primary seal, the overflow groove provides secondary protection to further prevent liquid from leaking into the external environment.
[0028] An outer overflow ring 321 is provided at the upper outer end of the overflow tank 32, and an inner ring 322 is provided at the upper inner end of the overflow tank 32. The height of the outer overflow ring 321 is twice that of the inner ring. The outer overflow ring 321 is provided at the upper outer end of the overflow tank 32 and has a height twice that of the inner ring. Through its height and position design, the outer overflow ring 321 guides the leaked liquid back into the overflow tank 32 to prevent the liquid from overflowing outside the overflow tank. The height of the outer overflow ring being twice that of the inner ring provides a higher protective wall, further enhancing the leak prevention ability of the overflow tank. In the case of a large amount of liquid leakage, the outer overflow ring effectively prevents the liquid from overflowing into the external environment through its height and design. The inner ring 322 is provided at the upper inner end of the overflow tank 32. The inner ring cooperates with the outer overflow ring to form a multiple protection structure, further enhancing the leak prevention ability of the overflow tank. The presence of the inner ring increases the sealing performance of the overflow tank, ensuring that the leaked liquid can be effectively collected and guided back.
[0029] A disc-shaped fixing seat 51 is provided at the lower end of the upper joint 5, and a second clamping portion 52 is provided at the upper end of the fixing seat 51. A disc-shaped fixing seat 51 is provided at the lower end of the upper joint 5. The fixing seat 51 provides a stable support surface to ensure a firm connection between the upper joint and the lower joint 3. Through the design of the fixing seat 51, the contact area between the upper joint and the lower joint is increased, further enhancing the sealing performance. A second clamping portion 52 is provided at the upper end of the fixing seat 51. The second clamping portion 52 is used to clamp with the lower joint 3 to ensure a tight connection between the upper joint 5 and the lower joint 3. Through the design of the clamping portion, the sealing performance between the joints is ensured, preventing the liquid from leaking from the joint seam.
[0030] A gasket 7 is provided between the lower joint 3 and the upper joint 5. The gasket 7 is used to fill the gap between the lower joint 3 and the upper joint 5, providing an additional sealing layer to prevent liquid leakage. The gasket 7 can absorb vibrations and impacts in the mechanical connection, prevent the joints from loosening during use, and ensure the stability of the connection. The gasket 7 can also prevent direct contact and wear between the joints, extending the service life of the assembly.
[0031] Working principle:
[0032] The water inlet hose 1 is fixed to the lower joint 3 through the lower clamp 4. The water outlet hose 2 is fixed to the upper joint 5 through the upper clamp 6. The gasket 7 is assembled between the lower joint 3 and the upper joint 5, and the lower joint 3 and the upper joint 5 are locked by screws.
[0033] When water flows from the water inlet hose 1 to the water outlet hose 2, since the water outlet hose 2 is sleeved on the outer wall of the upper joint 5, water may seep at the contact surface between the water outlet hose 2 and the upper joint 5. When there is seepage, the water will flow along the outer wall of the upper joint 5 into the overflow tank 32 in the lower joint. When the water level in the lower overflow tank 32 is higher than the inner ring 322, the water will seep through the gasket 7, turn over the inner ring and flow back into the water inlet hose 1, thus preventing water leakage.
[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
