Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically a three-way valve pipeline switching device for water-based coating production. Background Technology

[0002] With the deepening of environmental protection concepts and the vigorous development of the coatings industry, water-based coatings, with their low pollution and low volatility characteristics, are gradually becoming the mainstream in the market. In the production process of water-based coatings, the precise delivery of coatings and pipeline switching are key links to ensure production continuity, stability, and product quality.

[0003] However, traditional pipeline switching methods are cumbersome and inefficient, making it difficult to meet the stringent requirements of modern large-scale water-based coating production. Furthermore, the pipeline switching process requires the use of two sets of valves to work together, increasing installation costs. Utility Model Content

[0004] The purpose of this utility model is to provide a three-way valve pipeline switching device for water-based coating production, so as to solve the problem mentioned in the background art that two sets of valve bodies are required to cooperate with each other during the pipeline switching process, which increases the installation cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A three-way valve pipeline switching device for water-based coating production includes: a three-way pipe, one set of pipes of the three-way pipe being connected to a water-based coating conveying pipeline, and a semi-circular plate being fixedly installed on the outer surface of the other two sets of pipes of the three-way pipe, a semi-annular groove being formed in the semi-circular plate, and a sealing mechanism being slidably installed in the semi-annular groove.

[0007] Preferably, the semi-annular groove is connected to two sets of pipes in the tee pipe, so that the sealing mechanism can slide into one set of pipes in the tee pipe through the semi-annular groove to seal it.

[0008] Preferably, the sealing mechanism includes a sealing ring plate, which is slidably installed in a semi-annular groove, so that the sealing ring plate can be slidably inserted into one of the sets of pipes through the semi-annular groove to seal it.

[0009] Preferably, the outer surface of the sealing ring plate is fitted with a sealing ring.

[0010] Preferably, a toothed ring is embedded and fixedly installed at the lower end of the outer surface of the sealing ring plate. The toothed ring meshes with a gear, which is rotatably installed in a rotating groove. The rotating groove is opened in a semi-circular plate and communicates with a semi-annular groove.

[0011] Preferably, the gear rotating in the slot is fixedly connected to the output shaft of the motor, the motor is fixedly mounted on the semi-circular plate, and the output shaft of the motor rotates through the slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the design of the three-way pipe, semi-circular plate, rotating groove, semi-annular groove, and sealing mechanism, the three-way pipe switching is based on the change of valve core position of the three-way valve to achieve pipe switching. When it is necessary to switch water-based coating from one pipe to another, the sealing mechanism can be activated to slide to one end in the semi-annular groove until it slides into the pipe, thereby sealing one set of pipes, cutting off the connection with the original pipe, and thus changing the direction of coating flow. When it is necessary to seal another set of pipes to switch the direction of coating flow, the sealing mechanism can be reversed to seal the other set of pipes. It allows the traditional two sets of valve bodies to be replaced by a single three-way pipe and sliding sealing mechanism, thereby reducing the number of valves and connecting parts, thus reducing installation costs. Moreover, this sliding sealing is more suitable for the sealing control of high viscosity water-based coatings than traditional plug valves.

[0014] 2. Through the design of the motor, gears, sealing ring plate, and toothed ring, when switching water-based coatings from one pipeline to another, the motor is started to drive the gear to rotate in the rotating groove and simultaneously engage the toothed ring. The toothed ring is embedded and fixedly installed at the lower end of the sealing ring plate. This allows the rotating gear to drive the sealing ring plate to slide to one end in the semi-annular groove until the sealing ring plate slides into the pipeline, thus blocking one set of pipelines and cutting off the connection with the original pipeline, thereby changing the direction of coating flow. When it is necessary to block another set of pipelines to switch the direction of coating flow, the motor can be reversed to drive the sealing ring plate to block the other set of pipelines. The forward and reverse rotation of the motor can achieve the operation of blocking the pipeline and switching the direction of coating flow. This design greatly simplifies the system architecture, not only reducing the complexity of equipment design and manufacturing, but also making the installation process more convenient. It eliminates the need for repeated debugging of the coordinated operation of multiple valve bodies, saving a lot of manpower and time costs. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-4 This embodiment provides the following technical solution:

[0022] like Figures 1-3 As shown, a three-way valve pipeline switching device for water-based coating production includes: a three-way pipe 1, one set of pipes of the three-way pipe 1 being connected to a water-based coating conveying pipeline, and a semi-circular plate 101 fixedly installed on the outer surface of the other two sets of pipes of the three-way pipe 1. A semi-circular groove 103 is provided in the semi-circular plate 101, and a sealing mechanism 2 is slidably installed in the semi-circular groove 103. The semi-circular groove 103 is connected to two sets of pipes in the three-way pipe 1, so that the sealing mechanism 2 can slide into one set of pipes in the three-way pipe 1 through the semi-circular groove 103 to seal it.

[0023] Through the design of the three-way pipe 1, semi-circular plate 101, rotating groove 102, semi-annular groove 103, and sealing mechanism 2, the switching of the three-way pipe 1 is based on the change of the valve core position of the three-way valve to achieve pipeline switching. When it is necessary to switch the water-based coating from one pipeline to another, the sealing mechanism 2 can be activated to slide to one end in the semi-annular groove 103 until it slides into the pipeline, thereby achieving the operation of sealing one set of pipelines, cutting off the connection with the original pipeline, and thus changing the flow direction of the coating. When it is necessary to seal another set of pipelines to switch the flow direction of the coating, the sealing mechanism 2 can be reversed to achieve the sealing of the other set of pipelines. The traditional two sets of valve bodies can be replaced by a single three-way pipe 1 and sliding sealing mechanism 2, thereby reducing the number of valves and connecting parts, thus reducing the installation cost. Moreover, this sliding sealing is more suitable for the sealing control of high viscosity water-based coatings than traditional plug valves.

[0024] like Figure 4As shown, the sealing mechanism 2 includes a sealing ring plate 203, which is slidably installed in a semi-annular groove 103, allowing the sealing ring plate 203 to slide into one of the sets of pipes for sealing. A sealing ring 205 is embedded in the outer surface of the sealing ring plate 203. A toothed ring 204 is embedded in the lower end of the outer surface of the sealing ring plate 203 and meshes with a gear 202. The gear 202 is rotatably installed in a rotating groove 102, which is located within a semi-circular plate 101 and communicates with the semi-annular groove 103. The gear 202, rotating within the rotating groove 102, is fixedly connected to the output shaft of a motor 201, which is fixedly installed in the semi-circular plate 101, while the output shaft rotatably passes through the rotating groove 102.

[0025] Through the design of the motor 201, gear 202, sealing ring plate 203, and toothed ring 204, when switching water-based coatings from one pipeline to another, the motor 201 is started to drive the gear 202 to rotate within the rotating groove 102 and simultaneously engage the toothed ring 204. The toothed ring 204 is embedded and fixedly installed at the lower end of the sealing ring plate 203, allowing the rotating gear 202 to drive the sealing ring plate 203 to slide to one end within the semi-annular groove 103 until the sealing ring plate 203 slides into the pipeline, thus achieving the application of coatings to one set of pipelines. The blocking operation cuts off the connection with the original pipeline, thereby changing the direction of paint flow. When it is necessary to block another set of pipelines to switch the direction of paint flow, the motor 201 can be reversed to drive the sealing ring plate 203 to block the other set of pipelines. The blocking of pipelines and the switching of paint flow direction can be achieved by the forward and reverse rotation of the motor 201. This design greatly simplifies the system architecture, reduces the complexity of equipment design and manufacturing, and makes the installation process more convenient. It eliminates the need for repeated debugging of the coordinated operation of multiple valve bodies, saving a lot of manpower and time costs.

[0026] Based on the above technical solution, the working steps of this solution are summarized as follows: When it is necessary to switch the water-based coating from one pipeline to another, the motor 201 can be started to drive the gear 202 to rotate in the rotating groove 102 and simultaneously mesh with the toothed ring 204. The toothed ring 204 is embedded and fixedly installed at the lower end of the sealing ring plate 203. This allows the rotating gear 202 to drive the sealing ring plate 203 to slide to one end in the semi-annular groove 103 until the sealing ring plate 203 slides into the pipeline, thereby sealing one set of pipelines, cutting off the connection with the original pipeline, and thus changing the direction of the coating flow. When it is necessary to seal another set of pipelines to switch the direction of the coating flow, the motor 201 can be reversed to drive the sealing ring plate 203 to seal the other set of pipelines. The forward and reverse rotation of the motor 201 can achieve the operation of sealing the pipeline and switching the direction of the coating flow.

[0027] In summary: By replacing the traditional two sets of valve bodies with a single three-way pipe 1 and a sliding sealing ring plate 203, the number of valves and connecting parts are reduced, thereby reducing installation costs. Moreover, this sliding plug type is more suitable for sealing control of high-viscosity water-based coatings compared to traditional plug valves.
