Description

Technical Field

[0001] The utility model belongs to the technical field of desuperheating water pressure reduction, and particularly relates to a pressure reduction mechanism for desuperheating water for steam direct injection. Background Technique

[0002] The pressure reduction mechanism of desuperheating water is a device used to regulate and reduce the pressure of desuperheating water in a steam direct injection system, ensuring that the desuperheating water can be injected into the steam direct injection system at an appropriate pressure and temperature to meet specific process requirements and safety standards.

[0003] Currently, when the water source of desuperheating water is transported into the steam direct injection system, the pressure of the desuperheating water itself is relatively high. Therefore, before entering the steam direct injection system, a regulating valve is needed to regulate the pressure of the desuperheating water so that the water pressure of the desuperheating water is suitable for the working pressure required by the system. However, when regulating the water pressure of the desuperheating water, manual regulation is required, and the response speed of manual regulation is slow. When the demand for the water pressure of the desuperheating water in the system changes, it takes a certain amount of time for manual regulation to sense this change and make corresponding adjustments, resulting in a certain lag in water pressure regulation and affecting the efficiency during water pressure regulation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pressure reduction mechanism for desuperheating water for steam direct injection to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A pressure reduction mechanism for desuperheating water for steam direct injection, comprising:

[0006] A base, on the top surface of the base is provided a water tank. One end of the bottom of the water tank is connected to a water pump through a water pipe. The other end of the water pump is connected to a water delivery pipe for transporting desuperheating water through a bracket. A pressure reduction component for reducing the water pressure of the transported desuperheating water is provided on the surface of the water delivery pipe. When the moving plate of the pressure reduction component disengages from the contact with the first induction block, the first induction block controls the cylinder on the surface of the water delivery pipe to work, pushing the plugging block to adjust the size of the water outlet in the water delivery pipe, thereby reducing the water pressure of the transported desuperheating water.

[0007] Preferably, the pressure reduction component includes a protective shell and a sliding shell. The protective shell is provided on the surface of the water delivery pipe and the sliding shell is provided inside the protective shell and is communicated with the water delivery pipe. A first floating rod is provided inside the sliding shell, and the top of the first floating rod slides through the sliding shell and is connected to the moving plate. One end of the first floating rod located inside the sliding shell is connected to a first floating plate.

[0008] Preferably, a spring is sleeved on the surface of the first floating rod and both ends of the spring are respectively connected to the sliding shell and the first floating plate, and both ends of the bottom of the movable plate are connected to second sensing blocks and the second sensing block and the cylinder are electrically connected to the first sensing block.

[0009] Preferably, an adjusting shell is provided on the surface of the water delivery pipe, an adjusting plate is slidably connected to the adjusting shell via a slider, and the bottom of the adjusting plate is connected to the blocking block.

[0010] Preferably, the cylinder is arranged at the top of the regulating shell and the piston rod of the cylinder is movably penetrated through the regulating shell and connected to the regulating plate, and an arc seat is provided in the water pipe and at the bottom of the blocking block.

[0011] Preferably, a window shell is provided on the surface of the water pipe and a transparent window is provided on the surface of the window shell, a float is provided in the window shell and a second float rod is connected to the bottom of the float, one end of the second float rod is movably inserted through the water pipe and connected to the second float plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) By starting the water pump, the water pump draws the cooling water in the water tank into the water pipe for transportation through the water pipe. When the water pressure of the cooling water transported in the water pipe is too high, the cooling water in the water pipe lifts up the first floating plate, and the first floating plate pushes the first floating rod upward to move. When the first floating rod moves, it pushes the moving plate upward. When the moving plate moves, it drives the second sensing blocks at the two ends of the bottom to break away from the contact with the first sensing block. At this time, the first sensing block controls the cylinder to start, and the piston rod of the cylinder extends to push the adjusting plate to move. When the adjusting plate moves, it drives the blocking block to move toward the arc seat, so that the water outlet in the water pipe is reduced by the blocking block, so that the flow rate of the water outlet is reduced, thereby reducing the water pressure of the cooling water. The water outlet in the water pipe is adjusted by the blocking block pushed by the cylinder, which is more convenient and faster to adjust, avoiding the problem of slow adjustment speed affecting the water pressure regulation efficiency.

[0014] (2) When the pressure is reduced by the blocking block, the workers can observe the height of the float in the window shell to observe the water flow intensity of the water pipe. When the water pressure in the water pipe is too high and the cooling water flow is large, the cooling water will lift the second float plate and the second float rod to move upward, thereby driving the float to rise. After the pressure is reduced by the blocking block, the water pressure in the water pipe decreases and the cooling water flow becomes smaller. The second float plate loses its buoyancy and drives the second float rod and the float to move downward, thereby lowering the height of the float in the window shell. This makes it easier for workers to observe the water pressure in the water pipe so that they can take corresponding measures in time. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0019] 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.

[0020] The present utility model provides a pressure reducing mechanism for desuperheating water of steam direct injection as shown in Figures 1-3 and includes:

[0021] Base 1, on the top surface of the base 1, there is a water tank 2, one end of the bottom of the water tank 2 is connected to a water pump 4 through a water pipe 3, the other end of the water pump 4 is connected to a water delivery pipe 5 for delivering desuperheating water through a bracket, and a pressure reducing assembly 6 for reducing the water pressure of the delivered desuperheating water is provided on the surface of the water delivery pipe 5. When the moving plate 7 of the pressure reducing assembly 6 is separated from the contact with the first induction block 8, the first induction block 8 controls the air cylinder 9 on the surface of the water delivery pipe 5 to work, and the plugging block 10 is pushed to adjust the size of the water outlet 24 in the water delivery pipe 5, thereby reducing the water pressure of the delivered desuperheating water.

[0022] The pressure reducing assembly 6 includes a protective shell 11 and a sliding shell 12. The protective shell 11 is provided on the surface of the water delivery pipe 5, and the sliding shell 12 is provided in the protective shell 11 and communicated with the water delivery pipe 5. A first floating rod 13 is provided in the sliding shell 12, and the top of the first floating rod 13 slides through the sliding shell 12 and is connected to the moving plate 7. One end of the first floating rod 13 located in the sliding shell 12 is connected to a first floating plate 14.

[0023] A spring 15 is sleeved on the surface of the first floating rod 13, and both ends of the spring 15 are respectively connected to the sliding shell 12 and the first floating plate 14. Two ends of the bottom of the moving plate 7 are connected with second induction blocks 16, and the second induction blocks 16 and the air cylinder 9 are both electrically connected to the first induction block 8. The second induction blocks 16 and the first induction block 8 are electromagnetic induction sensors. When the second induction blocks 16 are separated from the first induction block 8, the first induction block 8 generates an electromagnetic induction effect and sends a control signal to the air cylinder 9 to control the operation of the air cylinder 9.

[0024] An adjustment shell 17 is arranged on the surface of the water delivery pipe 5. An adjustment plate 18 is connected to the bottom of the adjustment shell 17 through a slider in a sliding manner, and a blocking block 10 is connected to the bottom of the adjustment plate 18. The piston rod of the air cylinder 9 drives the adjustment plate 18 to move, and the adjustment plate 18 can drive the blocking block 10 to move.

[0025] The air cylinder 9 is arranged at the top of the adjustment shell 17, and the piston rod of the air cylinder 9 movably penetrates through the adjustment shell 17 and is connected to the adjustment plate 18. An arc-shaped seat 19 is arranged in the water delivery pipe 5 and at the bottom of the blocking block 10. When the blocking block 10 contacts the arc-shaped seat 19, the water delivery pipe 5 can be closed.

[0026] A window shell 20 is arranged on the surface of the water delivery pipe 5, and a transparent window is arranged on the surface of the window shell 20. A floating ball 21 is arranged in the window shell 20, and a second floating rod 22 is connected to the bottom of the floating ball 21. One end of the second floating rod 22 movably penetrates through the water delivery pipe 5 and is connected to the second floating plate 23. When the water pressure in the water delivery pipe 5 decreases, the second floating plate 23 loses buoyancy and drives the second floating rod 22 and the floating ball 21 to move downward, so that the height of the floating ball 21 in the window shell 20 becomes lower.

[0027] For the decompression mechanism of desuperheating water for direct steam injection, by starting the water pump 4 to work, the water pump 4 pumps the desuperheating water in the water tank 2 into the water delivery pipe 5 through the water pipe 3 for transportation. When the water pressure of the desuperheating water transported in the water delivery pipe 5 is too high, the desuperheating water in the water delivery pipe 5 jacks up the first floating plate 14. The first floating plate 14 pushes the first floating rod 13 to move upward, and when the first floating rod 13 moves, it pushes the moving plate 7 to move upward. When the moving plate 7 moves, it drives the second induction blocks 16 at both ends of the bottom to be separated from the first induction block 8. At this time, the first induction block 8 controls the air cylinder 9 to start. The piston rod of the air cylinder 9 extends to push the adjustment plate 18 to move, and when the adjustment plate 18 moves, it drives the blocking block 10 to move towards the arc-shaped seat 19, so as to adjust the outlet 24 in the water delivery pipe 5 to be smaller through the blocking block 10, reduce the flow rate of the outlet 24, thereby decompressing the water pressure of the desuperheating water, and adjusting the outlet 24 in the water delivery pipe 5 through the air cylinder 9 pushing the blocking block 10 is more convenient and the adjustment is relatively rapid, avoiding the problem that the adjustment speed is slow and affects the water pressure adjustment efficiency.

[0028] When decompressing through the plugging block 10, the height of the floating ball 21 in the viewing window housing 20 of the worker can be observed to observe the water flow intensity of the water delivery pipe 5. When the water pressure in the water delivery pipe 5 is too high and the desuperheating water flow rate is large, the desuperheating water will push up the second floating plate 23 and the second floating rod 22 to move upward, thereby driving the floating ball 21 to rise. After decompressing through the plugging block 10, when the water pressure in the water delivery pipe 5 decreases and the desuperheating water flow rate becomes small, the second floating plate 23 loses buoyancy and drives the second floating rod 22 and the floating ball 21 to move downward, so that the height of the floating ball 21 in the viewing window housing 20 becomes lower, which is convenient for workers to observe the water pressure condition in the water delivery pipe 5. And when the worker observes that the height of the floating ball 21 in the viewing window housing 20 becomes lower and the water flow rate becomes smaller, the cylinder 9 can be manually controlled to close.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
