Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler feedwater technology, and in particular to a boiler feedwater pressure stabilizing device. Background Technology
[0002] In chemical production, boilers are crucial equipment, providing the necessary heat energy for the production process. Traditional boiler feedwater systems typically rely on boiler feedwater pumps to directly deliver water to the boiler feedwater network. In actual operation, this method can lead to pressure fluctuations in the boiler feedwater network due to changes in production conditions and equipment failures. When pressure fluctuations are too large, they can easily affect the normal operation of the boiler, causing unstable steam output, which in turn affects the continuity of the production process and product quality. On the other hand, frequent pressure fluctuations can also impact the boiler, accelerating wear and damage, shortening its service life, and increasing maintenance costs and replacement frequency. Traditional feedwater systems lack effective buffering and pressure stabilization measures when dealing with water flow impacts and pressure changes, resulting in uneven water flow in the network and exacerbating damage to pipelines and equipment. Therefore, we have introduced a boiler feedwater pressure stabilizing device. Utility Model Content
[0003] The main objective of this invention is to provide a boiler feedwater pressure stabilizing device that can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A boiler feedwater pressure stabilizing device includes a fixed base and a boiler feedwater pump. A carbon steel pressure stabilizing tank is fixedly connected to the inner wall of the fixed base. An inlet pipe is fixedly installed through the upper part of the outer surface of the boiler feedwater pump. An input pipe is fixedly installed through the middle of the right end of the boiler feedwater pump, and the right end of the input pipe is fixedly connected through the lower left end of the carbon steel pressure stabilizing tank. A check valve is movably installed through the right part of the outer surface of the input pipe. A feedwater pressure stabilizing assembly is fixedly connected to the middle of the inner wall of the carbon steel pressure stabilizing tank. An output pipe is fixedly connected through the upper right end of the carbon steel pressure stabilizing tank. A boiler feedwater network is fixedly connected through the right end of the output pipe. A flow regulating valve is movably installed through the right part of the outer surface of the output pipe.
[0006] The water supply pressure stabilizing assembly includes a left pressure buffer assembly, a middle pressure buffer assembly is fixedly connected to the middle of the right end of the left pressure buffer assembly, a right pressure buffer assembly is fixedly connected to the right end of the middle pressure buffer assembly, and the right pressure buffer assembly and the left pressure buffer assembly have the same structure. The outer surfaces of the left pressure buffer assembly, the middle pressure buffer assembly and the right pressure buffer assembly are all fixedly connected to the inner wall of the carbon steel pressure stabilizing tank.
[0007] Preferably, the left pressure buffer assembly includes a left stainless steel partition and a right stainless steel partition, and a stainless steel spiral guide plate is fixedly connected between the left and right stainless steel partitions. Both the lower right end of the left stainless steel partition and the lower right end of the right stainless steel partition have elliptical guide holes that pass through to the left and right.
[0008] By adopting the above technical solution: when water flows in through the elliptical guide hole of the left stainless steel partition, it will flow along the spiral path under the guidance of the stainless steel spiral guide plate. This spiral flow method can greatly increase the flow path length of the water, so that the water consumes more kinetic energy in a limited space, thereby effectively slowing down the flow velocity. Compared with the traditional straight cylinder or simple partition buffer structure, the spiral guide plate design can make fuller use of space and efficiently decelerate the water flow, thereby stabilizing the water pressure entering the carbon steel pressure tank and avoiding instantaneous fluctuations in pipeline pressure caused by excessive water flow impact.
[0009] Preferably, the outer surfaces of the left stainless steel partition, the right stainless steel partition, and the stainless steel spiral guide plate are all fixedly connected to the inner wall of the carbon steel pressure stabilizing tank.
[0010] By adopting the above technical solution, the outer surfaces of the left stainless steel partition, the right stainless steel partition, and the stainless steel spiral guide plate are tightly attached to the inner wall of the carbon steel pressure tank, so that the left pressure buffer assembly can be perfectly matched with the internal space of the carbon steel pressure tank, thereby optimizing the water flow guidance path.
[0011] Preferably, the medium pressure buffer assembly includes a connecting rod, a medium stainless steel partition is fixedly sleeved on the middle of the outer surface of the connecting rod, the medium stainless steel partition has several Y-shaped guide grooves that pass through from left to right at its right end, the left end of the connecting rod is fixedly connected to the right end of the right stainless steel partition, and the right end of the connecting rod is fixedly connected to the left end of the right pressure buffer assembly.
[0012] By adopting the above technical solution: when the water flow, after being initially buffered by the left pressure buffer component, impacts the middle stainless steel baffle, the unique bifurcated structure of the Y-shaped guide channel can further disperse the water flow. Compared with a simple straight hole or single-channel structure, the Y-shaped guide channel can make the water flow form multiple branches when passing through. These branches interact and collide, further consuming the kinetic energy of the water flow and slowing down the flow rate, thereby achieving a more refined and efficient buffering of the water flow, which helps to further stabilize the water pressure.
[0013] Preferably, the outer surface of the stainless steel partition is fixedly connected to the inner wall of the carbon steel pressure stabilizing tank.
[0014] By adopting the above technical solution, after the water flows into the medium-pressure buffer assembly, due to the fixed connection between the stainless steel partition and the carbon steel pressure stabilizing tank, the water flow is precisely guided to the Y-shaped guide channel. There will be no water leakage or bypass phenomenon caused by the gap between the stainless steel partition and the carbon steel pressure stabilizing tank wall. This ensures that the water flow can fully interact with the Y-shaped guide channel, maximize the dispersion, deceleration and buffering functions of the Y-shaped guide channel on the water flow, significantly improve the overall device's ability to regulate water flow pressure, and provide a strong guarantee for outputting stable pressure water supply.
[0015] Preferably, several of the Y-shaped guide channels are arranged in a circular array around the center of the stainless steel partition and extend from the inside out.
[0016] By adopting the above technical solution, Y-shaped guide channels distributed in a circular array around the center of the stainless steel partition plate are used to ensure that the water flow entering the medium-pressure buffer component can be guided and flowed evenly.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] In this invention, by setting up a carbon steel pressure stabilizing tank and an internal water supply pressure stabilizing group, the incoming water flow is buffered and regulated in multiple ways. The left pressure buffer component, the middle pressure buffer component, and the right pressure buffer component in the water supply pressure stabilizing group decelerate, disperse, and change the flow direction of the water flow in sequence, making the water flow more stable in the carbon steel pressure stabilizing tank, effectively reducing the impact and fluctuation of the water flow, thereby stabilizing the pressure output to the boiler feedwater network and reducing the impact of network pressure fluctuations on the production process system.
[0019] In this invention, the check valve installed on the right side of the outer surface of the input pipe effectively prevents water in the carbon steel pressure stabilizing tank from flowing back to the boiler feed pump, avoiding damage to the boiler feed pump and pressure imbalance caused by backflow, thus ensuring the normal operation of the system and equipment safety. The flow regulating valve on the right side of the outer surface of the output pipe can flexibly adjust the water flow according to actual needs and control the amount of water entering the boiler feed network. This not only helps to stabilize the pressure of the boiler feed network, but also allows for water volume adaptation according to different production conditions, improving the flexibility and adaptability of the system operation.

[0029] Example 1
[0030] A boiler feedwater pressure stabilizing device includes a fixed base 10 and a boiler feedwater pump 2. A carbon steel pressure stabilizing tank 1 is fixedly connected to the inner wall of the fixed base 10. An inlet pipe 3 is fixedly installed through the upper part of the outer surface of the boiler feedwater pump 2. An input pipe 4 is fixedly installed through the middle of the right end of the boiler feedwater pump 2, and the right end of the input pipe 4 is fixedly connected through the lower left end of the carbon steel pressure stabilizing tank 1. A check valve 5 is movably installed through the right part of the outer surface of the input pipe 4. A feedwater pressure stabilizing assembly 6 is fixedly connected to the middle of the inner wall of the carbon steel pressure stabilizing tank 1. An output pipe 7 is fixedly connected through the upper right end of the carbon steel pressure stabilizing tank 1. A boiler feedwater network 8 is fixedly connected through the right end of the output pipe 7. A flow regulating valve 9 is movably installed through the right part of the outer surface of the output pipe 7.
[0031] In this embodiment, the water supply pressure stabilizing assembly 6 includes a left pressure buffer assembly 61, a middle pressure buffer assembly 62 fixedly connected to the middle of the right end of the left pressure buffer assembly 61, and a right pressure buffer assembly 63 fixedly connected to the right end of the middle pressure buffer assembly 62. The right pressure buffer assembly 63 and the left pressure buffer assembly 61 have the same structure. The outer surfaces of the left pressure buffer assembly 61, the middle pressure buffer assembly 62, and the right pressure buffer assembly 63 are all fixedly connected to the inner wall of the carbon steel pressure stabilizing tank 1. The left pressure buffer assembly 61 includes a left stainless steel partition 611 and a right stainless steel partition 612. A stainless steel spiral guide plate 613 is fixedly connected between the left stainless steel partition 611 and the right stainless steel partition 612. Both the lower right end of the left stainless steel partition 611 and the lower right end of the right stainless steel partition 612 have left and right through openings. Elliptical guide hole 614; the outer surfaces of the left stainless steel partition 611, the right stainless steel partition 612, and the stainless steel spiral guide plate 613 are all fixedly connected to the inner wall of the carbon steel pressure stabilizing tank 1; the medium pressure buffer assembly 62 includes a connecting rod 621, a medium stainless steel partition 622 is fixedly sleeved on the middle of the outer surface of the connecting rod 621, the right end of the medium stainless steel partition 622 has several Y-shaped guide grooves 623 that pass through left and right, the left end of the connecting rod 621 is fixedly connected to the right end of the right stainless steel partition 612, and the right end of the connecting rod 621 is fixedly connected to the left end of the right pressure buffer assembly 63; the outer surface of the medium stainless steel partition 622 is fixedly connected to the inner wall of the carbon steel pressure stabilizing tank 1; the several Y-shaped guide grooves 623 are distributed in a ring array around the center of the medium stainless steel partition 622 and extend from the inside to the outside.
[0032] It should be noted that this utility model is a boiler feedwater pressure stabilizing device. During use, the valve on the inlet pipe 3 is opened to allow water to enter the boiler feedwater pump 2. At this time, under the action of the boiler feedwater pump 2, the water is transported to the carbon steel pressure stabilizing tank 1 through the input pipe 4. The check valve 5 on the right side of the outer surface of the input pipe 4 prevents the water in the carbon steel pressure stabilizing tank 1 from flowing back to the boiler feedwater pump 2, ensuring that the water flows into the carbon steel pressure stabilizing tank 1 in a one-way manner. After the water enters the carbon steel pressure stabilizing tank 1, it first impacts the left pressure buffer component 61. The water flows through the elliptical guide hole 614 on the left stainless steel partition 611 into the stainless steel spiral guide plate 613. The stainless steel spiral guide plate 613 between the left stainless steel partition 611 and the right stainless steel partition 612 changes the direction of the water flow, causing it to flow along a spiral path and slowing down the flow rate. Then, the water continues to flow to the right through the elliptical guide hole 614 on the right stainless steel partition 612. The water flow, after initial buffering, reaches the medium pressure buffer component 62, where it impacts... The stainless steel baffle 622 in the middle, and the Y-shaped guide grooves 623 arranged in a ring array and extending from the inside to the outside on its right end, further change the direction, disperse the water flow, reduce the flow velocity, and play a second buffering role. After the second buffering, the water flow enters the right pressure buffer assembly 63. The right pressure buffer assembly 63 has the same structure as the left pressure buffer assembly 61, repeating the buffering process of the left pressure buffer assembly 61, and slowing down and dispersing the water flow again, making the water flow more stable in the carbon steel pressure stabilizing tank 1. After the water pressure stabilizing group 6 has fully buffered and stabilized the water, it flows out from the output pipe 7 at the upper right end of the carbon steel pressure stabilizing tank 1. The flow regulating valve 9 on the right side of the outer surface of the output pipe 7 adjusts the water flow according to actual needs, controls the amount of water entering the boiler feed water network 8, thereby stabilizing the pressure of the boiler feed water network 8. Finally, the water enters the boiler feed water network 8 and then the boiler through the part where the right end of the output pipe 7 is inserted and fixedly connected to the boiler feed water network 8, completing the entire pressure stabilizing water supply process.
