Description

Technical Field

[0001] This utility model relates to the technical field of pressure reducers, specifically a de-temperature pressure reducer with a multi-hole valve core. Background Technology

[0002] The main function of a desuperheating and pressure reducing device is to reduce high-temperature and high-pressure steam to the low-temperature and low-pressure steam required by the customer. It usually consists of a pressure reducing system, a desuperheating system, a safety protection device, and an automatic control device. However, existing desuperheating and pressure reducing devices have certain defects in use. In particular, under the action of the pressure reducing system and the desuperheating system, some steam pressure still exceeds the specified value, causing this steam to be discharged into the atmosphere by the spring safety valve in the safety protection device, resulting in a waste of resources.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese Patent No. CN 217108367 U, published on August 2, 2022) provides a novel high-efficiency desuperheating and pressure reducing device, comprising a pipe 1 and a pipe 2 connected by a pressure reducing and throttling pipe. A circular plate is fixedly connected inside the pressure reducing and throttling pipe, and a trapezoidal groove is opened on the right side of the circular plate. A sleeve is fixedly connected to the center of the right wall of the trapezoidal groove, and a fixing rod is inserted into the sleeve. A baffle is fixedly connected to the left end of the fixing rod. A spring is fitted over the sleeve and the fixing rod, with one end of the spring fixed to the inner right wall of the trapezoidal groove and the other end fixed to the right wall of the baffle. Several throttling holes penetrate the right side of the trapezoidal groove. By adding a pressure reducing and throttling pipe, the steam after pressure reduction and desuperheating is subjected to secondary pressure reduction, ensuring that all steam remains within the allowable value. This improves the pressure reducing effect of the desuperheating and pressure reducing device, and prevents the generation of steam with pressure exceeding the specified value. Consequently, the steam is no longer discharged into the atmosphere, thus avoiding resource waste and promoting energy conservation and environmental protection.

[0004] Existing technologies perform pressure reduction operations using pressure-reducing throttling tubes, circular plates, trapezoidal grooves, sleeves, fixed rods, and spring assemblies. However, these materials require high precision machining and are difficult to manufacture, thus increasing production and maintenance costs. Furthermore, springs are prone to fatigue or damage under high temperature and pressure conditions, affecting the pressure reduction effect. The overall pressure reduction relies on a fixed spring and sleeve structure, making it impossible to flexibly adjust the pressure reduction effect according to different working conditions, which limits the overall adaptability and pressure reduction efficiency.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing desuperheater and pressure reducer with a multi-hole valve core. Therefore, we proposed that a desuperheater and pressure reducer with a multi-hole valve core can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a depressurizing and pressure reducing device with a multi-hole valve core, in order to solve the problems mentioned in the background art. Currently, the depressurization operation in the market is carried out by depressurizing throttling tubes, circular plates, trapezoidal grooves, sleeves, fixed rods and spring assemblies. However, these materials require high precision machining and are difficult to manufacture, which increases production and maintenance costs. In addition, the springs are prone to fatigue or damage under high temperature and high pressure conditions, affecting the depressurization effect. The overall depressurization relies on a fixed spring and sleeve structure, which cannot flexibly adjust the depressurization effect according to different working conditions, thus limiting the overall adaptability and depressurization efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a desuperheating and pressure reducing device with a multi-hole valve core, comprising a valve body and a delivery pipe, wherein the delivery pipe is connected to the side end of the valve body, a maintenance component is provided at the bottom of the valve body, a driving component is installed inside the valve body, a valve core is connected below the driving component, the valve core is located inside the valve body, two pairs of through holes are symmetrically opened on the valve core, and the two pairs of through holes have different diameters, and a pressure gauge is installed on the valve body.

[0008] Preferably, a cooling component is provided on the outside of the conveying pipe. The cooling component includes a protective cover installed on the outside of the conveying pipe, and a second pipe is provided inside the protective cover. The second pipe is arranged in a spiral shape.

[0013] Preferably, the baffle is provided with a transmission hole, and a conveying component is connected to the end of the baffle, the conveying component being provided with a transmission hole.

[0014] Preferably, the side end of the conveyor box is provided with an arc-shaped opening, which is adapted to the conveyor component.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This depressurizer with a multi-hole valve core can precisely adjust the medium pressure by controlling the rotation angle and speed of the driving component to meet the pressure requirements under different working conditions. It also reduces energy loss and equipment wear that may occur with traditional pressure reduction methods. The valve core has two pairs of symmetrically arranged through holes of different diameters, enhancing the adjustment range and accuracy of pressure reduction. It can adapt to changes in the pressure of various media, improving the applicability and versatility of the equipment, and reducing the problem of increased production and maintenance costs caused by the use of auxiliary structures. The specific details are as follows:

[0016] (1) By controlling the rotation angle and speed of the drive components, the medium pressure can be precisely adjusted to meet the pressure requirements under different working conditions, reducing the energy loss and equipment wear that may be caused by traditional pressure reduction methods. The through holes on the valve core enhance the adjustment range and accuracy of pressure reduction, and improve the applicability and versatility of the equipment.

[0017] (2) Cooling water is transported through the cooling water delivery valve. The cooling water is transported to the delivery box through the first pipeline, which facilitates the mixing of the cooling water with the transported medium for cooling operation. This can quickly reduce the temperature of the medium and improve product quality and production efficiency.

[0018] (3) Cooling water is transmitted through the second pipe. The spiral second pipe increases the contact area and contact time between the cooling water and the conveying pipe, enhances the cooling effect on the conveying pipe, improves the service life of the second pipe and the reliability of equipment operation, and the noise reduction components inside the protective cover can improve the working environment.

[0019] (4) When the cooling water pressure is less than the spring force on the guide rod, the cooling water is transported to the inside of the conveying box through the transmission hole on the baffle on the outside of the guide rod, and flows out through the transmission hole on the conveying component and the arc-shaped opening on the side of the conveying box, which facilitates the cooling operation.

[0020] (5) When the cooling water pressure is greater than the spring force on the guide rod, the water pressure pushes the baffle on the guide rod, causing the baffle to squeeze the spring on the outside of the guide rod to move, which facilitates the baffle to move the conveying part into the arc-shaped opening, so that the cooling water is sprayed out from the conveying hole on the conveying part, thus improving the automation level of the equipment.

[0030] 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.

[0031] Example 1: In this example, the combination of through holes 6 with different diameters enhances the adjustment range and accuracy of pressure reduction, enabling it to adapt to changes in the pressure of various media, thus improving the applicability and versatility of the equipment. Figures 1-4The technical solution shown includes a valve body 1 and a conveying pipeline 2. The conveying pipeline 2 is connected to the side of the valve body 1, and a maintenance component 3 is located at the bottom of the valve body 1. A drive component 5 is installed inside the valve body 1, and a valve core 4 is connected below the drive component 5. The valve core 4 is located inside the valve body 1 and has two pairs of symmetrical through holes 6 with different diameters. A pressure gauge 7 is installed on the valve body 1. The valve body 1 is conveniently connected to the conveying pipeline 2. The maintenance component 3 is located below the valve body 1, which facilitates maintenance operations by personnel without the need for complicated disassembly, greatly reducing maintenance difficulty and improving the maintainability and service life of the equipment. The drive component 5 drives the valve core 4 to rotate inside the valve body 1, and the pressure of the conveyed medium is reduced through the interaction of the through holes 6 on the valve core 4. This is an overall pressure reduction operation. The device is simple to operate. By controlling the rotation angle and speed of the drive component 5, the medium pressure can be precisely adjusted to meet the pressure requirements under different working conditions. At the same time, it reduces the energy loss and equipment wear that may be caused by traditional pressure reduction methods. The valve core 4 has two pairs of through holes 6 symmetrically opened, and the two pairs of through holes 6 have different diameters. The combination of through holes 6 with different diameters enhances the adjustment range and accuracy of pressure reduction, which can adapt to the changes in the pressure of various media, improves the applicability and versatility of the equipment, and has a simple overall structure. This reduces the problem of increased production and maintenance costs caused by the use of auxiliary structures. In addition, the pressure gauge 7 set on the valve body 1 allows for quick and easy viewing of the internal pressure of the valve body 1. The operator can monitor the internal pressure status of the equipment in real time, promptly detect abnormal pressure conditions, and take corresponding measures to ensure the safety and stability of the equipment operation.

[0032] Example 2: In this example, the spiral-shaped second pipe 12 increases the contact area and contact time between the cooling water and the conveying pipe 2, further enhancing the cooling effect on the conveying pipe 2, specifically as follows: Figures 2-6As shown, a cooling assembly is installed on the outside of the conveying pipe 2. The cooling assembly includes a protective cover 13 installed on the outside of the conveying pipe 2. A second pipe 12 is installed inside the protective cover 13. The second pipe 12 is spirally arranged. A first pipe 10 is connected through the protective cover 13. A cooling water conveying valve 9 is installed on the first pipe 10. A conveying box 11 is installed at the end of the first pipe 10 that passes through the inside of the conveying pipe 2. The second pipe 12 passes through the protective cover 13 and is connected to the first pipe 10. A noise reduction component 14 is installed inside the protective cover 13. A thermometer 8 for temperature measurement is installed on the conveying pipe 2. The thermometer 8 is located at the side end of the protective cover 13. Cooling water is conveyed through the cooling water conveying valve 9. The cooling water is conveyed through the first pipe 10 to the conveying box 11 and then conveyed inside the conveying box 11 to facilitate the mixing of the cooling water with the conveyed medium, thereby performing a cooling operation. This can quickly reduce the temperature of the medium, meet the temperature requirements of the production process, and improve product quality and production efficiency. The temperature sensor 8 on the conveying pipe 2 facilitates monitoring of the overall temperature and adjustment of the cooling water delivery, thereby achieving precise cooling and avoiding over- or under-cooling, thus improving energy efficiency. When cooling water is delivered through the first pipe 10, a portion is transmitted through the second pipe 12. The second pipe 12 is located inside the protective cover 13 outside the conveying pipe 2 and is spirally arranged. This spiral shape increases the contact area and contact time between the cooling water and the conveying pipe 2, further enhancing the cooling effect. Simultaneously, the protective cover 13 protects the second pipe 12 from external damage, improving its service life and the reliability of equipment operation. Noise reduction components 14 are installed inside the protective cover 13, effectively reducing noise generated during equipment operation, improving the working environment, and reducing the harm of noise to workers.

[0033] Example 3: In this example, the water flows out through the conveying hole 19 on the conveying component 18 and the arc-shaped opening 20 on the side of the conveying box 11, facilitating cooling operations. Specifically, as shown below... Figure 2 and Figures 5-8As shown, the conveying box 11 is equipped with an auxiliary component, which includes a guide rod 15 installed inside the conveying box 11. A baffle 16 is movably connected to the outside of the guide rod 15, and a spring 17 is sleeved on the outside of the guide rod 15. A transmission hole is opened on the baffle 16, and a conveying component 18 is connected to the end of the baffle 16. A conveying hole 19 is opened on the conveying component 18. An arc-shaped opening 20 is provided on the side end of the conveying box 11, which is adapted to the conveying component 18. When cooling water is transported into the conveying box 11 through the first pipe 10, when the cooling water pressure is less than the elastic force of the spring 17 on the guide rod 15, the cooling water is transported into the conveying box 11 through the transmission hole on the baffle 16 outside the guide rod 15. The cooling water flows out through the conveying hole 19 on the conveying component 18 and the arc-shaped opening 20 on the side of the conveying box 11, facilitating cooling operations. The overall structure is simple and easy to maintain. When the cooling water pressure is greater than the spring force of the spring 17 on the guide rod 15, the water pressure pushes the baffle 16 on the guide rod 15, causing the baffle 16 to press the spring 17 on the outside of the guide rod 15 and move. This allows the baffle 16 to move the conveying component 18 into the arc-shaped opening 20, so that the cooling water is sprayed out from the conveying hole 19 on the conveying component 18. This improves the accuracy and effectiveness of cooling and enhances the automation level of the equipment. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
