Description

Technical Field

[0001] This utility model relates to the field of water-cooled butterfly valve technology, specifically a detachable water-cooled butterfly valve with replaceable valve core. Background Technology

[0002] A butterfly valve is a type of valve that controls the flow and cut-off of media in a pipeline by rotating a disc-shaped butterfly plate. When the butterfly plate is perpendicular to the pipeline axis, the valve is closed. When the butterfly plate rotates, it forms an angle with the pipeline axis, allowing the media to flow through the gaps on both sides of the butterfly plate. The larger the opening, the greater the flow rate. When the butterfly plate is parallel to the pipeline axis, the valve is fully open, allowing unobstructed flow of the media. A water-cooled butterfly valve is a type of butterfly valve specifically designed for high-temperature environments. It uses a built-in cooling system to ensure the normal operation of the valve under high-temperature conditions. The opening and closing element of the water-cooled butterfly valve is a circular butterfly plate that rotates around its own axis within the valve body to achieve opening, closing, or regulation functions. At the same time, through circulating coolant, it directly acts on the heat-sensitive area of ​​the butterfly plate, absorbing and dissipating the heat generated during operation, ensuring that the valve material is not deformed or damaged by high temperatures.

[0003] During the cooling process, the newly introduced cooling water does not have enough time to absorb heat because the flow time of the cooling water in the valve core is short, resulting in an unsatisfactory cooling effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model achieves this through the following technical solution: a detachable, replaceable valve core water-cooled butterfly valve, comprising:

[0005] A valve body, wherein a heightening block is fixedly installed on the top of the valve body, and a motor is fixedly installed on the top of the heightening block, the output end of the motor passing through the heightening block and extending into its interior;

[0006] A valve shaft and a valve core, wherein the valve shaft is installed inside the valve body and the valve core is installed outside the valve shaft;

[0007] The valve core includes a semi-circular plate. A water collection chamber is formed inside the semi-circular plate near the valve shaft. The water collection chamber is symmetrically installed along the center of the axis of the semi-circular plate. An outer arc cavity is formed inside the semi-circular plate and is located outside the water collection chamber. The outer arc cavity and the water collection chamber cooperate with each other and are connected by a connecting cavity. During operation, water first enters the upper water collection chamber, and then flows through the connecting cavity, passing through the outer arc cavity and entering the lower water collection chamber. This allows the cooling water to flow in a tortuous manner inside the valve core, increasing the residence time of the cooling water in the valve core and improving the water cooling effect. A connecting cavity is formed between the outer arc cavity and the water collection chamber, and the outer arc cavity and the water collection chamber are connected by the connecting cavity.

[0008] Preferably, the semicircular plate has symmetrical through grooves on the side near the valve shaft, and the through grooves are connected to the water accumulation chamber. A connecting plate is fixedly installed on the outer side of the semicircular plate, and the semicircular plate is fixedly connected to the valve shaft through the connecting plate.

[0009] Preferably, the valve shaft includes a slotted shaft, the top end of which is fixedly connected to the output end of the motor via a coupling, and a sealing ring is fixedly installed on the outer side of the slotted shaft. The outer side of the sealing ring has an annular groove, and the sealing ring is symmetrically installed along the center position of the slotted shaft. The sealing ring is rotatably adapted to the inner wall of the valve body through the annular groove, and the opposite face of the sealing ring is fixedly connected to the non-opposite face of the connecting plate. Both ends of the outer side of the slotted shaft have arc-shaped slots, and an outer ring cover is rotatably installed at each arc-shaped slot of the slotted shaft. An inlet pipe is fixedly installed on the outer side of the upper outer ring cover, and an outlet pipe is fixedly installed on the outer side of the lower outer ring cover.

[0010] Preferably, the outer side of the through-slot shaft is symmetrically provided with side through-slots, and the side through-slots of the through-slot shaft correspond one-to-one with the through-slots of the semi-circular plate. The inner wall of the side through-slots is symmetrically provided with water guiding cavities. The water guiding cavities cooperate with the side through-slots, and the water guiding cavities are not directly connected to each other. During the flow process, the cooling water introduced into the valve shaft must flow through the valve core and absorb the heat of the valve core before entering the water guiding cavity below. This avoids the cooling water being directly discharged after being introduced, without enough time to absorb heat, resulting in an unsatisfactory cooling effect. The water guiding cavities are not connected to each other, and the water guiding cavities are connected to the inside of the outer ring cover through arc through-slots.

[0011] This utility model provides a detachable, replaceable valve core water-cooled butterfly valve. It has the following advantages:

[0012] (I) This split-type replaceable valve core water-cooled butterfly valve uses the outer arc cavity and the water accumulation cavity to cooperate and use the connecting cavity to connect the outer arc cavity and the water accumulation cavity. During operation, water first enters the upper water accumulation cavity, and then flows through the connecting cavity to enter the lower water accumulation cavity after passing through the outer arc cavity. This allows the cooling water to flow in a tortuous manner inside the valve core, increasing the residence time of the cooling water in the valve core and improving the water cooling effect.

[0013] (II) This split-type replaceable valve core water-cooled butterfly valve uses a water guide cavity and a side passage groove to cooperate. At the same time, the water guide cavities are not directly connected. During the flow process, the cooling water introduced into the valve shaft must flow through the valve core and absorb the heat of the valve core before entering the water guide cavity below. This avoids the cooling water that has just been introduced being directly discharged without enough time to absorb heat, resulting in an unsatisfactory cooling effect. Attached Figure Description

[0026] Valve shaft 2 and valve core 3 are installed inside valve body 1 and valve core 3 is installed outside valve shaft 2.

[0027] The valve core 3 includes a semi-circular plate 31. A water accumulation chamber 34 is provided inside the semi-circular plate 31 on the side near the valve shaft 2. The water accumulation chamber 34 is symmetrically installed along the center of the axis of the semi-circular plate 31. An outer arc cavity 33 is provided inside the semi-circular plate 31. The two semi-circular plates 31 form a circle to control the flow path of the valve body 1. At the same time, during cooling, cooling water is introduced into the upper water accumulation chamber 34 through the upper through groove of the valve shaft 2, so that the water first accumulates in the upper water accumulation chamber 34. The outer arc cavity 33 is located outside the water accumulation chamber 34. A connecting cavity 35 is provided between the outer arc cavity 33 and the water accumulation chamber 34. The outer arc cavity 33 and the water accumulation chamber 34 are connected through the connecting cavity 35.

[0028] The semicircular plate 31 has symmetrical through grooves on one side near the valve shaft 2, and the through grooves are connected to the water accumulation chamber 34. A connecting plate 32 is fixedly installed on the outer side of the semicircular plate 31. The connecting chamber 35 connects the water accumulation chamber 34 and the outer arc chamber 33 to absorb the heat of the semicircular plate 31 during operation and reduce the temperature of the valve core 3. Then, the water is introduced back into the valve shaft 2 for discharge through the connecting chamber 35 and the water accumulation chamber 34 below. The semicircular plate 31 is fixedly connected to the valve shaft 2 through the connecting plate 32.

[0029] The valve shaft 2 includes a slotted shaft 21. The top end of the slotted shaft 21 is fixedly connected to the output end of the motor 5 via a coupling. A sealing ring 23 is fixedly installed on the outer side of the slotted shaft 21. The outer side of the sealing ring 23 has an annular groove. The sealing ring 23 is symmetrically installed along the center position of the slotted shaft 21. The sealing ring 23 is rotatably adapted to the inner wall of the valve body 1 through the annular groove. The opposite face of the sealing ring 23 is fixedly connected to the non-opposing face of the connecting plate 32. Both ends of the outer side of the slotted shaft 21 have arc-shaped through grooves, and the water inlet pipe 2... 2. A cooling pipe is connected to the outlet pipe 24, so that water is introduced into the upper outer ring cover 25 through the inlet pipe 22, and then introduced into the upper water guide cavity 27 through the arc groove at the top. Then, the water guide cavity 27 cooperates with the side groove 26 to introduce water into the valve core 3 to cool the valve core 3. The outer ring cover 25 is rotatably installed at the arc groove of the through groove shaft 21. The inlet pipe 22 is fixedly installed on the outer side of the upper outer ring cover 25, and the outlet pipe 24 is fixedly installed on the outer side of the lower outer ring cover 25.

[0030] The outer side of the through shaft 21 is symmetrically provided with side through grooves 26. The side through grooves 26 of the through shaft 21 correspond one-to-one with the through grooves of the semi-circular plate 31. After the water completes heat absorption in the valve core 3, it is introduced into the water guide cavity 27 below through the lower side through groove 26, and finally discharged through the water outlet pipe 24. The inner wall of the side through groove 26 is symmetrically provided with water guide cavities 27. The water guide cavities 27 are not connected to each other, and the water guide cavities 27 are connected to the inside of the outer ring cover 25 through the arc through groove.

[0031] In use, the cooling pipe is connected to the valve shaft 2, and the motor 5 drives the valve shaft 2 to rotate. During the rotation of the valve shaft 2, the valve core 3 rotates inside the valve body 1, controlling the operation of the flow path of the valve body 1. At the same time, during operation, the cooling pipe introduces coolant into the valve shaft 2, and then into the valve core 3 through the valve shaft 2 for water cooling and to ensure the normal operation of the butterfly valve.

[0032] In the valve core 3, two semicircular plates 31 form a circle to control the flow path of the valve body 1. At the same time, during cooling, cooling water is introduced into the upper water accumulation chamber 34 through the upper through groove of the valve shaft 2, so that the water first accumulates in the upper water accumulation chamber 34. Then, the water accumulation chamber 34 is connected to the outer arc chamber 33 through the connecting chamber 35, absorbing the heat of the semicircular plates 31 during operation and reducing the temperature of the valve core 3. Then, the water is introduced back into the valve shaft 2 for discharge through the lower connecting chamber 35 and the water accumulation chamber 34.

[0033] In valve shaft 2, a cooling pipe is connected to water inlet pipe 22 and water outlet pipe 24, so that water is introduced into the upper outer ring cover 25 through water inlet pipe 22, and then into the upper water guide cavity 27 through the arc groove at the top. Then, the water guide cavity 27 cooperates with the side groove 26 to guide the water into valve core 3 to cool the valve core 3. After the water absorbs heat in the valve core 3, it is introduced into the lower water guide cavity 27 through the lower side groove 26, and finally discharged through water outlet pipe 24.
