Technical Field

[0001] The utility model relates to the technical field of electric valves, in particular to a high-temperature and high-pressure electric valve with anti-leakage function. Background Art

[0002] The high-temperature and high-pressure electric valve with anti-leakage function plays a key role in industrial applications. It can accurately control the fluid flow in the pipeline, and at the same time maintain the sealing performance under high-temperature and high-pressure environments to prevent leakage. This kind of valve usually adopts special materials and designs, and can withstand the pressure and temperature under extreme conditions to ensure the safe and stable operation of the system.

[0003] In the prior art, the utility model with the publication number of CN217328700U provides a high-temperature and high-pressure electric valve with anti-leakage function, which can effectively solve the problems that the existing electric valve in the background art is easily impacted by large flow rates during use, resulting in loose closing of the electric valve, affecting the use effect of the electric valve, and prone to leakage.

[0004] However, it is found in the actual use process that the above valve is only connected to the pipeline through a flange, which may cause the electric valve to bear too high internal pressure. This not only easily causes damage between the valve and the pipeline, but also cannot effectively reduce the pressure inside the valve body, reducing the operation flexibility and safety, and increasing the maintenance difficulty and cost. The present application provides a high-temperature and high-pressure electric valve with anti-leakage function to meet the requirements. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and provide a high-temperature and high-pressure electric valve with anti-leakage function.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A high-temperature and high-pressure electric valve with anti-leakage function, including a first pipeline, on which a second flange is provided. Inside the first pipeline, a first inner ring is provided, on which an inner ring groove is opened. Inside the inner ring groove, a blocking ball is provided. Outside the first inner ring, a second spring is provided, and outside the second spring, an outer plate is provided.

[0007] As a preferred embodiment, on the second flange, a fixing rod is provided, on which a third spring is provided. At both ends of the fixing rod, nuts are provided. On the side of the fixing rod away from the second flange, a first flange is provided.

[0008] The technical effects of adopting the above technical solution are as follows: A fixing rod is provided on the second flange. Elastic support is provided by the third spring on the fixing rod to maintain the stability and shock absorption of the structure. Nuts two at both ends of the fixing rod are used to adjust the position and pre-tightening force of the fixing rod to adapt to different working conditions, making the connection between the first flange and the second flange more reliable, capable of withstanding certain external forces and vibrations, and ensuring the normal operation of the system.

[0009] As a preferred embodiment, a fixing collar is provided on the second inner ring, and a clamping groove is provided on the side of the second inner ring away from the fixing collar.

[0010] The technical effects of adopting the above technical solution are as follows: A fixing collar is provided on the second inner ring. This design realizes the stable positioning of the second inner ring through the fixing collar, enhancing the firmness of the overall structure. The setting of the clamping groove provides a clamping method, making the equipment more stable after connection.

[0011] As a preferred embodiment, the pressure relief component includes a pressure relief housing. A support plate is provided inside the pressure relief housing. A fixing shaft is provided on the support plate. A blocking plate is provided on the fixing shaft. A first spring is provided at the top of the blocking plate. A first spring is provided at the top of the fixing shaft away from the first spring. A nut one is provided at the top of the fixing shaft away from the pressure plate.

[0012] The technical effects of adopting the above technical solution are as follows: When the internal pressure increases, the first spring is compressed, and the blocking plate will move along the fixing shaft to release the pressure, ensuring the stability of the pressure inside the system. The nut one is used to adjust the pre-tightening force of the first spring to set the pressure relief threshold. This design ensures that the equipment operates within a safe pressure range, preventing equipment damage or danger caused by excessive pressure.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0014] The present utility model is provided with a first pipe, a second pipe, a second spring, a first inner ring, an inner ring groove, a blocking ball, a fixing collar, a clamping groove, a second inner ring, and an outer plate. By providing the first pipe and the second pipe as fluid channels, the outer plate is ejected by the elastic force of the second spring, so that the clamping groove inside the outer plate is firmly clamped with the fixing collar to form a stable connection. At the same time, the first inner ring and the second inner ring realize the rapid positioning and locking between the inner rings through the interaction between the blocking ball in the inner ring groove and the clamping groove, not only improving the assembly efficiency of the equipment, but also enhancing the sealing performance and anti-vibration ability of the connection part, ensuring the safety of the equipment under high pressure, and being able to solve the problems mentioned in the background technology.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Such as Figure 1 - Figure 3As shown in the figure, this embodiment provides a technical solution: a high-temperature and high-pressure electric valve with anti-leakage function, including a first pipeline 1, on which a second flange 10 is provided. Inside the first pipeline 1, a first inner ring 6 is arranged, and an inner ring slot 7 is opened on the first inner ring 6. A blocking ball 8 is arranged in the inner ring slot 7. A second spring 5 is arranged outside the first inner ring 6, and an outer plate 16 is arranged outside the second spring 5. By setting the first pipeline 1 and the second pipeline 2 as fluid channels, the outer plate 16 is ejected by the elastic force of the second spring 5, so that the clamping slot inside the outer plate 16 is firmly clamped with the fixed collar 13, forming a stable connection. At the same time, through the interaction between the blocking ball 8 in the inner ring slot 7 of the first inner ring 6 and the clamping slot 14, the first inner ring 6 and the second inner ring 15 achieve rapid positioning and locking between the inner rings. These designs work together to not only improve the assembly efficiency of the equipment, but also enhance the sealing performance and anti-vibration ability of the connection, ensure the safety of the equipment under high pressure, and solve the technical problem of unstable pipeline fixation.

[0025] Further, as Figure 2 - Figure 3 shown: A fixed rod 9 is arranged on the second flange 10, a third spring 11 is arranged on the fixed rod 9, nuts 12 are arranged at both ends of the fixed rod 9, and a first flange 3 is arranged on the side of the fixed rod 9 away from the second flange 10. By providing elastic support through the third spring 11 on the fixed rod 9, the stability and shock absorption of the structure can be effectively maintained. The nuts 12 at both ends of the fixed rod 9 can be used to adjust the position and pre-tightening force of the fixed rod 9 to adapt to different working conditions, making the connection between the first flange 3 and the second flange 10 more reliable, capable of withstanding certain external forces and vibrations, and thus ensuring the normal operation of the system.

[0026] To solve the problem of excessive pressure inside the valve body, as Figure 4 shown: In this solution, the pressure relief component 4 includes a pressure relief housing 41, a support plate 42 is arranged inside the pressure relief housing 41, a fixed shaft 43 is arranged on the support plate 42, a blocking plate 44 is arranged on the fixed shaft 43, a first spring 45 is arranged on the top of the blocking plate 44, a first spring 45 is arranged on the top of the fixed shaft 43 away from the first spring 45, and a nut 47 is arranged on the top of the fixed shaft 43 away from the pressure plate 46. When the internal pressure of the system rises, the first spring 45 is compressed, causing the blocking plate 44 to move along the fixed shaft 43, thereby opening the pressure relief port to release excessive pressure and ensuring that the pressure inside the system is maintained within a safe range. The pre-tightening force of the first spring 45 can be adjusted through the nut 47, so as to set an accurate pressure relief threshold, which not only improves the safety of the equipment, but also ensures the stability and reliability during continuous operation.

[0027] Working principle:

[0028] As Figure 1 - Figure 4 shown below:

[0029] In use: During the installation of the device, by setting the first pipe 1 and the second pipe 2 as the channels for the fluid, the fluidity of the fluid and the normal operation of the system are ensured. Utilizing the elastic force of the second spring 5, the outer plate 16 is ejected, causing the card slot inside the outer plate 16 to firmly engage with the fixed collar 13, forming a stable connection. At the same time, the first inner ring 6 and the second inner ring 15 interact with the clamping slot 14 through the blocking ball 8 in the inner ring slot 7, achieving rapid positioning and locking between the inner rings. These designs work together not only to improve the assembly efficiency of the device but also to enhance the sealing performance and anti-vibration ability at the connection, ensuring the safety and stability of the device under high pressure or complex working conditions. Through the elastic support provided by the third spring 11 on the fixed rod 9, the stability and shock absorption of the structure can be effectively maintained. The nuts 12 at both ends of the fixed rod 9 can be used to adjust the position and pre-tightening force of the fixed rod 9 to adapt to different working conditions. This design makes the connection between the first flange 3 and the second flange 10 more reliable, capable of withstanding certain external forces and vibrations, thus ensuring the normal operation of the system. When the internal pressure of the system increases, the first spring 45 is compressed, causing the blocking plate 44 to move along the fixed shaft 43, thereby opening the pressure relief port to release excessive pressure and ensuring that the pressure inside the system is maintained within a safe range. The pre-tightening force of the first spring 45 can be adjusted through the nut 47, thereby setting an accurate pressure relief threshold. This design not only improves the safety of the device but also ensures the stability and reliability during continuous operation.

[0030] The above is only a preferred embodiment of the present invention and is not a limitation to the present invention in any other form. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
