Description

Technical Field

[0001] This utility model relates to the field of steam pipeline technology, specifically a steam pipeline pressure stabilizing mechanism. Background Technology

[0002] Steam pipeline pressure stabilization refers to the technical means of controlling pressure fluctuations in steam during transmission and supply within the allowable range of the process through specific mechanisms (such as multi-stage pressure reducing valves, U-tubes, solenoid valves, etc.). Its core principle is to address the characteristic of steam being susceptible to pressure fluctuations caused by factors such as temperature, flow rate, and pipeline resistance. Through the synergistic effects of pressure reduction regulation, gas-liquid separation, and flow control, pressure fluctuations are offset to stabilize the output pressure within the target value.

[0003] In the production of foamed flat sheet materials, the vulcanizing machine requires a stable steam supply. Existing steam pipeline pressure stabilization mechanisms mostly use U-shaped tubes to separate gas and liquid to ensure steam dryness. However, after long-term use, a single U-shaped tube is prone to internal scale buildup, requiring machine shutdown and disassembly for cleaning, which leads to production interruption and affects efficiency. It is difficult to adapt to the requirements of continuous production for equipment stability and continuity. Therefore, we propose a steam pipeline pressure stabilization mechanism. Utility Model Content

[0007] The pressure stabilizing mechanism includes a first pressure reducing valve fixedly connected to the top surface of the mounting plate. The outlet end of the first pressure reducing valve is fixedly connected to a first three-way pipe. Both ends of the first three-way pipe away from the first pressure reducing valve are fixedly connected to a first isolation valve. The outlet end of the first isolation valve is fixedly connected to a first L-shaped pipe.

The inlet end of the solenoid valve is fixedly connected to a second three-way pipe. Both ends of the second three-way pipe away from the solenoid valve are fixedly connected to a second isolation valve. The inlet end of the second isolation valve is fixedly connected to a second L-shaped pipe.

A U-shaped pipe is provided between the first L-shaped pipe and the second L-shaped pipe.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4As shown, a steam pipeline pressure stabilizing mechanism includes a mounting plate 1. A pressure stabilizing mechanism 4 is disposed on the upper surface of the mounting plate 1. The pressure stabilizing mechanism 4 includes a first pressure reducing valve 41 fixedly connected to the top surface of the mounting plate 1. A first tee pipe 42 is fixedly connected to the outlet end of the first pressure reducing valve 41. A first isolation valve 43 is fixedly connected to both ends of the first tee pipe 42 away from the first pressure reducing valve 41. A first L-shaped pipe 44 is fixedly connected to the outlet end of the first isolation valve 43. A first flange 45 is fixedly connected to the end of the first L-shaped pipe 44 away from the first isolation valve 43. A solenoid valve 404 is also fixedly connected to the top surface of the mounting plate 1. A second tee pipe 403 is fixedly connected to the inlet end of the solenoid valve 404. A second isolation valve 402 is fixedly connected to both ends of the second tee pipe 403 away from the solenoid valve 404. The inlet end of the second isolation valve 402 is fixedly connected to a second L-shaped pipe 401. The end of the second L-shaped pipe 401 away from the second isolation valve 402 is fixedly connected to a fourth flange 49. The side walls of the first flange 45 and the fourth flange 49 that are close to each other are respectively movably connected to a second flange 46 and a third flange 48. The side walls of the second flange 46 and the third flange 48 that are close to each other are jointly fixedly connected to a U-shaped pipe 47. The first flange 45 and the second flange 46, as well as the third flange 48 and the fourth flange 49, are all fixed with external bolts and nuts. The outlet end of the solenoid valve 404 is fixedly connected to a connecting pipe 405. The end of the connecting pipe 405 away from the solenoid valve 404 is fixedly connected to a second pressure reducing valve 406. The bottom end of the second pressure reducing valve 406 is fixedly connected to the top surface of the mounting plate 1.

[0024] It should be noted that the walls of both U-shaped tubes 47 are lined with high-temperature resistant glass to facilitate observation of the internal condition of the U-shaped tubes 47.

[0025] In specific implementation, by closing the first isolation valve 43 and the second isolation valve 402 on one side of the first three-way pipe 42, gas is transmitted through the U-shaped pipe 47 on the other side of the first three-way pipe 42. The first flange 45, the second flange 46, the third flange 48, and the fourth flange 49 on the closed side are disassembled, and the U-shaped pipe 47 can be removed for internal cleaning. This achieves the effect of cleaning the U-shaped pipe 47 without stopping the machine, which is convenient for use.

[0026] The high-pressure steam is first initially reduced in pressure by the first pressure reducing valve 41, which weakens the upstream pressure fluctuations. Then it flows into the U-shaped pipe 47, where the condensate and impurities settle under gravity, achieving gas-liquid separation and improving the dryness of the steam. At the same time, the curved structure buffers minor pressure fluctuations. The purified steam enters the solenoid valve 404, which precisely controls the on / off timing according to the vulcanizing machine process requirements, adjusting the steam supply rhythm. Subsequently, the steam enters the second pressure reducing valve 406 for secondary pressure stabilization, ultimately providing stable and dry steam to the vulcanizing machine and ensuring the vulcanization quality of the foamed flat material.

[0027] As a technical optimization of this utility model, a base plate 2 is provided below the mounting plate 1, and a lifting mechanism 3 is provided on the top surface of the base plate 2. The lifting mechanism 3 includes an electric push rod 31 fixedly connected to the middle of the top surface of the base plate 2. The telescopic end of the electric push rod 31 is fixedly connected to the bottom surface of the mounting plate 1. The lifting mechanism 3 also includes two telescopic rods 32 fixedly connected to both sides of the top surface of the base plate 2. The telescopic ends of the two telescopic rods 32 are both fixedly connected to the bottom surface of the mounting plate 1.

[0028] In practice, by adjusting the telescopic end of the electric push rod 31 to drive the telescopic rod 32 to extend and retract, the device can be adjusted to a specified height for use, thus enhancing the practicality of the device.

[0029] In use, this utility model adjusts the telescopic rod 32 by adjusting the telescopic end of the electric push rod 31 to extend or retract, thus adjusting the device to a specified height for use. The first pressure reducing valve 41 and the second pressure reducing valve 406 are connected to the steam pipeline. High-pressure steam is first initially reduced in pressure by the first pressure reducing valve 41, weakening upstream pressure fluctuations. It then flows into the U-shaped pipe 47, where condensate and impurities settle under gravity, achieving gas-liquid separation and improving steam dryness. Simultaneously, the curved structure buffers minor pressure fluctuations. The purified steam enters the solenoid valve 404, which is precisely adjusted according to the vulcanizing machine process requirements. The timing of the on / off switch is precisely controlled to adjust the steam supply rhythm. Subsequently, the steam enters the second pressure reducing valve 406 for secondary pressure stabilization, ultimately providing stable and dry steam to the vulcanizing machine to ensure the vulcanization quality of the foamed flat material. When it is necessary to clean the U-tube 47, the first isolation valve 43 and the second isolation valve 402 on the same side of the U-tube 47 to be cleaned are closed. Gas is transmitted through the U-tube 47 on the other side of the first tee pipe 42. The first flange 45, the second flange 46, the third flange 48, and the fourth flange 49 on the closed side are disassembled, and the U-tube 47 is removed for internal cleaning.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
