Description

Technical Field

[0001] This utility model relates to the field of coaxial valve technology, specifically a high-temperature resistant coaxial valve. Background Technology

[0002] A coaxial valve is an industrial valve, and the piston rod is the key component that realizes the opening and closing action of the valve. A pneumatic coaxial valve uses compressed air to force the piston to reciprocate, thereby opening and closing the valve. The medium pressure acts on the valve seat, and the piston is almost unaffected by resistance, so the valve can be opened or closed quickly. With the improved internal structure of the valve, the medium flow can be better and the pressure loss can be smaller.

[0003] However, existing technologies still have the following problems:

[0004] Most existing coaxial valves have limited high-temperature resistance. Many existing coaxial valves are not equipped with a cooling circulation system. When working in high-temperature environments, they cannot dissipate the heat generated by the valve body and side pipe in a timely and effective manner, causing the valve temperature to rise continuously. Excessive temperature will accelerate the aging and damage of internal sealing materials, valve cores and other components. Rubber seals are prone to losing elasticity at high temperatures, resulting in a decrease in sealing performance and leakage problems. Metal parts may also deform due to high temperatures, affecting the normal opening and closing and precision control of the valve.

[0005] To address the aforementioned problems, the inventors proposed a high-temperature resistant coaxial valve to solve them. Utility Model Content

[0006] In order to solve the problem of limited high-temperature resistance of coaxial valves, the purpose of this utility model is to provide a high-temperature resistant coaxial valve.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a high-temperature resistant coaxial valve, including a base plate, a valve body fixedly provided on the upper side of the base plate, and a side tube provided on the side of the valve body. A cooling sleeve is fitted on the outer surface of the valve body and the side tube. A cylinder is provided on one side of the valve body, and a piston rod is fixedly provided at the output end of the cylinder. The piston rod passes through the valve body and extends into the valve body.

[0008] Preferably, a circulating water tank is provided inside the cooling sleeve, and an inlet pipe and an outlet pipe are provided on one side of the outer surface of the cooling sleeve. A water pump and a water tank are fixedly provided on the upper surface of the base plate. One end of the inlet pipe is fixedly connected to the water pump, and the water pump is connected to the water tank. One end of the outlet pipe is fixedly connected to a radiator, and a cooling fan is provided on the upper surface of the radiator. The radiator is connected to the water tank.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention utilizes a cooling circulation system composed of a cooling sleeve, a water pump, and a radiator to effectively dissipate the heat generated by the valve body and side pipes, reducing the valve temperature and enabling the valve to operate stably in high-temperature environments. This significantly improves the valve's high-temperature resistance and service life. Attached Figure Description

[0016] 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.

[0017] Example: Figure 1-3As shown, this utility model provides a high-temperature resistant coaxial valve, including a base plate 1, a valve body 2 fixedly mounted on the upper side of the base plate 1, and a side tube 21 mounted on the side of the valve body 2. A cooling sleeve 4 is fitted onto the outer surfaces of the valve body 2 and the side tube 21. A cylinder 3 is mounted on one side of the valve body 2, and a piston rod 31 is fixedly mounted on the output end of the cylinder 3. A support tube 33 is fixedly mounted on the upper surface of the base plate 1, and the support tube 33 is fixedly connected to the cylinder 3. The output end of the cylinder 3 passes through the support tube 33. The support tube 33 enhances the stability of the cylinder 3, enabling it to output power more stably during operation, ensuring the movement accuracy of the piston rod 31 and the piston head 32, and further improving the valve's performance. To ensure overall stability and reliability, the piston rod 31 passes through the valve body 2 and extends into the valve body 2. A piston head 32 is fixedly provided at the end of the piston rod 31. In this high-temperature coaxial valve, the cylinder 3 is the key component for controlling the opening and closing of the valve. When it is necessary to open or close the valve, the cylinder 3 starts to work and outputs power to push the piston rod 31 to move linearly. Since the piston rod 31 passes through the valve body 2 and extends into the valve body 2, and a piston head 32 is fixedly provided at the end, the movement of the piston rod 31 drives the piston head 32 to move within the valve body 2. When the piston head 32 moves to the appropriate position, the valve opening or closing action is realized, thereby controlling the flow of fluid in the valve body 2 and the side pipe 21.

[0018] The piston rod 31 is relatively long, which allows the piston head 32 to have a greater stroke within the valve body 2. This means the valve can achieve a wider range of opening adjustment, from slight opening to full opening. The flow rate of the fluid can be precisely controlled according to actual working needs. In some industrial production processes with strict flow control requirements, the piston head 32 can be moved by the longer piston rod 31 to more accurately meet the flow requirements at different stages. The valve opening and closing is achieved by using a cylinder 3 to control the movement of the piston rod 31 and the piston head 32. This control method can accurately control the degree of valve opening and closing, ensuring that the flow rate and velocity of the fluid in the pipeline are accurately controlled, thus improving the control accuracy and reliability of the valve.

[0019] A circulating water tank 41 is provided inside the cooling sleeve 4. An inlet pipe 43 and an outlet pipe 45 are provided on one side of the outer surface of the cooling sleeve 4. The ends of the inlet pipe 43 and the outlet pipe 45 both penetrate the cooling sleeve 4 and extend into the circulating water tank 41. A water pump 44 and a water tank 42 are fixedly mounted on the upper surface of the base plate 1. One end of the inlet pipe 43 is fixedly connected to the water pump 44, and the water pump 44 is connected to the water tank 42. One end of the outlet pipe 45 is fixedly connected to a radiator 46. A cooling fan 47 is provided on the upper surface of the radiator 46. The lower surface of the radiator 46 is fixedly connected to the base plate 1, and the radiator 46 is connected to the water tank 42. The main function of the cooling sleeve 4 is to cool the valve body 2 and... The side pipe 21 is cooled to ensure that the valve can work normally in a high-temperature environment. After the water pump 44 starts, it draws water from the water tank 42 and delivers it to the circulating water tank 41 in the cooling sleeve 4 through the water inlet pipe 43. The water flows in the circulating water tank 41, absorbing the heat generated by the valve body 2 and the side pipe 21 due to the high temperature. The hot water after absorbing the heat flows out from the water outlet pipe 45 and enters the radiator 46. The cooling fan 47 on the radiator 46 starts to work, accelerates the air flow, and cools down the hot water in the radiator 46. The water after cooling flows back to the water tank 42, forming a complete cooling cycle system that continuously dissipates heat for the valve and ensures the valve's high-temperature resistance.

[0020] The upper surface of the water tank 42 is provided with a water exchange pipe 48, and a pipe cover 49 is attached to the upper surface of the water exchange pipe 48. The water exchange pipe 48 on the water tank 42 allows for water exchange and maintenance when the water in the water tank 42 needs to be replaced or maintained. The pipe cover 49 can be opened to perform the relevant operations through the water exchange pipe 48, ensuring good water quality in the water tank 42 and thus ensuring the normal operation of the cooling circulation system. The water exchange pipe 48 and pipe cover 49 on the water tank 42 facilitate the replacement and maintenance of the water in the water tank 42, ensuring the water quality of the cooling circulation system, reducing equipment failures caused by water quality problems, and lowering the maintenance cost and difficulty of the equipment.

[0021] Working principle: In this high-temperature coaxial valve, cylinder 3 is the key component for controlling the opening and closing of the valve. When it is necessary to open or close the valve, cylinder 3 starts to work and outputs power to push piston rod 31 to move linearly. Since piston rod 31 passes through valve body 2 and extends into valve body 2, and piston head 32 is fixed at the end, the movement of piston rod 31 drives piston head 32 to move in valve body 2. When piston head 32 moves to the appropriate position, the valve opening or closing action is realized, thereby controlling the flow of fluid in valve body 2 and side pipe 21.

[0022] The main function of the cooling sleeve 4 is to cool the valve body 2 and the side pipe 21 to ensure that the valve works normally in a high-temperature environment. After the water pump 44 starts, it draws water from the water tank 42 and delivers it to the circulating water tank 41 in the cooling sleeve 4 through the water inlet pipe 43. The water flows in the circulating water tank 41 and absorbs the heat generated by the valve body 2 and the side pipe 21 due to the high temperature. The hot water after absorbing the heat flows out from the water outlet pipe 45 and enters the radiator 46.

[0023] The cooling fan 47 on the radiator 46 starts to work, accelerates the air flow, and cools down the hot water in the radiator 46. After being cooled down, the water flows back to the water tank 42, forming a complete cooling cycle system that continuously cools the valve and ensures the valve's high temperature resistance.

[0024] The water tank 42 is equipped with a water exchange pipe 48. When it is necessary to replace or maintain the water in the water tank 42, the pipe cover 49 can be opened and the relevant operations can be carried out through the water exchange pipe 48 to ensure that the water quality in the water tank 42 is good, thereby ensuring the normal operation of the cooling circulation system.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
