Description

Technical Field

[0001] This utility model belongs to the field of vacuum valve technology, specifically relating to a vacuum valve cylinder cooling assembly with a split-type combined water cooling jacket. Background Technology

[0002] During the operation of a vacuum valve, its valve stem is usually driven by a hydraulic cylinder to achieve push-pull action. During this driving process, the connection between the hydraulic cylinder and the valve stem is prone to generating a large amount of local heat due to conduction from the mold. If this heat cannot be dissipated in time, it will cause the temperature of the hydraulic oil inside the cylinder to rise and the aging of the seals to accelerate, thereby affecting the operational stability and service life of the vacuum valve. Therefore, it is necessary to effectively cool the hydraulic cylinder and related heat-generating parts. In the existing technology, the cooling method for vacuum valve cylinders mostly adopts the idea of ​​setting up a cooling structure outside the cylinder. For example, adding a cooling water channel on the cooling plate next to the cylinder, or trying to directly put a cooling water jacket on the outside of the cylinder. In order to improve the cooling efficiency, some solutions are designed to make the cooling water flow in a spiral shape inside the water jacket, so as to extend the contact path between the water flow and the outer wall of the cylinder and enhance the heat exchange effect. However, the above-mentioned spiral cooling water jacket has significant technical bottlenecks in actual processing. The processing of the complete spiral channel inside the water jacket is extremely difficult. The traditional one-piece molding process not only requires special and complex equipment, but also easily leads to problems such as insufficient channel size accuracy and excessive inner wall roughness, resulting in increased water flow resistance and decreased cooling uniformity. At the same time, the processing cost is high and the yield rate is low. In summary, the current cooling structure of vacuum valve cylinders still has room for improvement in terms of processing feasibility and cooling efficiency. There is an urgent need for a cooling solution that can simplify the spiral water channel processing technology, improve the cooling effect, and is easy to implement, so as to solve the shortcomings of the existing technology. Utility Model Content

[0003] The purpose of this invention is to provide a vacuum valve cylinder cooling assembly with a split-type combined water cooling jacket. This assembly eliminates the need for complex equipment, reduces processing difficulty and cost, improves dimensional accuracy and yield, and overcomes the bottleneck of one-piece molding technology. It effectively dissipates heat, delays the aging of seals, improves the operational stability and service life of the vacuum valve, and meets high-load cooling requirements.

[0004] The specific technical solution adopted by this utility model is as follows: A vacuum valve cylinder cooling assembly with a split-type water-cooling jacket includes a mounting plate. A cylinder body is mounted on the top of the mounting plate, and a cooling plate is mounted on the bottom of the mounting plate. Both the mounting plate and the cooling plate have through grooves. The stroke rod of the cylinder body passes through the through grooves on the mounting plate and the cooling plate and extends to the lower part of the cooling plate. The cylinder body is wrapped with a water-cooling jacket body, and heat dissipation structures are respectively installed in the water-cooling jacket body and the cooling plate.

[0005] The heat dissipation structure includes a first heat dissipation structure and a second heat dissipation structure. The first heat dissipation structure is assembled inside the cooling plate, and the second heat dissipation structure is assembled inside the water cooling jacket body. The first heat dissipation structure includes a water channel disposed inside the cooling plate, the water channel being arranged around the stroke rod of the cylinder body; The second heat dissipation structure includes a spiral flow channel disposed inside the water cooling jacket body, the spiral flow channel being arranged around the oil cylinder body.

[0006] The cooling plate is provided with an annular flow channel, which is located on the outside of the output end of the cylinder body, and both ends of the annular flow channel are respectively connected to the water flow channel.

[0007] The water-cooling jacket body includes an outer mounting sleeve and an inner mounting sleeve. The inner mounting sleeve is located inside the outer mounting sleeve and is installed on the outside of the cylinder body. The outer mounting sleeve is fixed to the outside of the inner mounting sleeve. The spiral flow channel includes an inner half-flow channel and an outer half-flow channel. The inner half-flow channel is located outside the inner mounting sleeve, and the outer half-flow channel is located inside the outer mounting sleeve. When the outer mounting sleeve and the inner mounting sleeve are combined, the inner half-flow channel and the outer half-flow channel are combined to form the spiral flow channel.

[0008] Two sealing spiral rings are fixed on the inner side of the outer mounting sleeve, and the sealing spiral rings are arranged parallel to the outer half-flow channel. Two sealing spiral grooves are provided on the outer side of the inner mounting sleeve, and the sealing spiral grooves are arranged parallel to the inner half-flow channel. When the outer mounting sleeve and the inner mounting sleeve are combined, the two sealing spiral rings are respectively inserted into the sealing spiral grooves.

[0009] A sealing abutment ring is fixed inside the outer mounting sleeve and between the two sealing spiral rings, and the sealing abutment ring abuts against the inner mounting sleeve.

[0010] The sealing ring is made of flexible material, and the material of the sealing ring is rubber.

[0011] The technical effects achieved by this utility model are as follows: This invention processes the outer and inner mounting sleeves separately and then welds them together, eliminating the need for complex equipment, reducing processing difficulty and cost, improving dimensional accuracy and yield, solving the bottleneck of one-piece molding technology, and through the setting of water flow channels, it can dissipate heat from the stroke rod of the cylinder body, thereby effectively dissipating heat, delaying the aging of seals, improving the operational stability and service life of the vacuum valve, and meeting the high-load cooling requirements.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] like Figures 1-5 As shown, a vacuum valve cylinder cooling assembly with a split-type combined water-cooling jacket includes a mounting plate 1. A cylinder body 2 is mounted on the top of the mounting plate 1, and a cooling plate 3 is mounted on the bottom of the mounting plate 1. The cooling plate 3 and the mounting plate 1 can be a single plate, namely the mounting cooling plate. The first heat dissipation structure described below can be set inside the mounting cooling plate. Both the mounting plate 1 and the cooling plate 3 are provided with through grooves 7. The stroke rod of the cylinder body 2 passes through the through grooves 7 on the mounting plate 1 and the cooling plate 3 and extends to the lower part of the cooling plate 3. The outside of the cylinder body 2 is wrapped with a water-cooling jacket body 4, and heat dissipation structures are respectively installed inside the water-cooling jacket body 4 and the cooling plate 3. The vacuum valve uses the cylinder body 2 to control the up and down movement of its valve rod, thereby realizing the opening and closing of the vacuum valve.

[0016] See attached document Figures 3-5 The heat dissipation structure includes a first heat dissipation structure and a second heat dissipation structure. The first heat dissipation structure is assembled inside the cooling plate 3, and the second heat dissipation structure is assembled inside the water cooling jacket body 4. The first heat dissipation structure includes a water channel 5 disposed inside the cooling plate 3. The water channel 5 surrounds the stroke rod of the cylinder body 2. A water pipe is connected to the outside of the cooling plate 3. By assembling components such as a water pump on the water pipe, water is introduced into the water channel 5 through the water pipe, and the water channel 5 carries away the heat on the stroke rod of the cylinder body 2, thereby achieving the effect of heat dissipation for the stroke rod. An annular flow channel 6 is disposed inside the cooling plate 3, and the annular flow channel 6 is disposed outside the output end of the cylinder body 2. Both ends of the annular flow channel 6 are connected to the water channel 5. The arrangement of the annular flow channel 6 allows it to surround the stroke rod, and increases the path of the water channel 5 around the stroke rod of the cylinder body 2, thereby further increasing the heat dissipation effect and isolating the heat conducted from the mold. The second heat dissipation structure includes a spiral flow channel set inside the water cooling jacket body 4. The spiral flow channel surrounds the oil cylinder body 2. A water pipe is connected to the outside of the water cooling jacket body 4. By assembling components such as a water pump on the water pipe, water is introduced into the spiral flow channel through the water pipe. The spiral shape ensures a long flow path in the spiral flow channel, thereby achieving the effect of heat dissipation for the oil cylinder body 2.

[0017] See attached document Figure 5 The water-cooled jacket body 4 includes an outer mounting sleeve 41 and an inner mounting sleeve 42. The inner mounting sleeve 42 is located inside the outer mounting sleeve 41 and is installed on the outside of the cylinder body 2. The outer mounting sleeve 41 is fixed on the outside of the inner mounting sleeve 42. The spiral flow channel includes an inner half-flow channel 43 and an outer half-flow channel 44. The inner half-flow channel 43 is located outside the inner mounting sleeve 42, and the outer half-flow channel 44 is located inside the outer mounting sleeve 41. When the outer mounting sleeve 41 and the inner mounting sleeve 42 are combined, the inner half-flow channel 43 and the outer half-flow channel 44 merge to form a spiral flow channel. It is not convenient to directly machine the spiral flow channel inside the water-cooling jacket body 4. With this arrangement, the outer mounting sleeve 41 and the inner mounting sleeve 42 are machined separately. The inner half-flow channel 43 is machined on the outside of the inner mounting sleeve 42, while the outer half-flow channel 44 is machined on the outside of the outer mounting sleeve 41. 1. After completion, the outer mounting sleeve 41 and the inner mounting sleeve 42 are joined together through welding and other processes, forming a spiral flow channel between the inner semi-flow channel 43 and the outer semi-flow channel 44. This ensures the simplicity and convenience of the processing technology. Two sealing spiral rings 45 are fixed inside the outer mounting sleeve 41, and the sealing spiral rings 45 are arranged parallel to the outer semi-flow channel 44. Two sealing spiral grooves 46 are provided on the outer side of the inner mounting sleeve 42, and the sealing spiral grooves 46 are arranged parallel to the inner semi-flow channel 43. When the outer mounting sleeve 41 and the inner mounting sleeve 42 are joined together, the two sealing spiral rings 45 are respectively inserted into the sealing spiral channel 43. Within the sealing spiral groove 46, this arrangement allows the sealing spiral ring 45 to isolate the spiral flow channel formed by the inner half-flow channel 43 and the outer half-flow channel 44 from the remaining parts of the outer mounting sleeve 41 and the inner mounting sleeve 42, thereby increasing the sealing performance of the spiral flow channel. The sealing spiral ring 45 can be made of materials such as rubber, allowing it to deform when the outer mounting sleeve 41 is fitted onto the inner mounting sleeve 42. When the sealing spiral ring 45 corresponds to the sealing spiral groove 46, it can be inserted into the sealing spiral groove 46. Furthermore, the outer mounting sleeve 4... A sealing abutment ring 47 is fixed on the inner side and between the two sealing spiral rings 45. The sealing abutment ring 47 abuts against the inner mounting sleeve 42. The sealing abutment ring 47 abuts against the two sealing spiral rings 45, increasing the fit between the sealing spiral ring 45 and the inner wall at the edge of the sealing spiral groove 46, and further increasing the sealing effect. The sealing abutment ring 47 is made of flexible material, and the material of the sealing abutment ring 47 is rubber, which makes the deformation of the sealing abutment ring 47 greater, thereby ensuring the abutment effect of the sealing abutment ring 47 against the sealing spiral ring 45.

[0018] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
