Description

Technical Field

[0001] The utility model belongs to the technical field of globe valves, and particularly relates to a desuperheating water throttling globe valve. Background Technique

[0002] A desuperheating water throttling globe valve is a valve used to control the flow of fluid. Especially in water treatment and water supply systems, the main function of this valve is to control the flow rate of fluid by adjusting the flow velocity, so as to achieve the purpose of energy conservation and reduction of water resource waste. However, there are some problems in the use of traditional desuperheating water throttling globe valves. Water hammer effect is likely to occur, which may cause damage to the pipeline system. The water hammer effect refers to the pressure fluctuation generated due to the inertial effect of the fluid when the fluid suddenly stops or changes direction in the pipeline. This pressure fluctuation may cause vibration or damage to equipment such as pipelines and valves, and even may lead to safety accidents. Therefore, we propose a desuperheating water throttling globe valve. Content of the Utility Model

[0003] The purpose of the utility model is to provide a desuperheating water throttling globe valve. By setting a pressure reducing mechanism, when water flows through, it can only flow out through the arc holes on the surfaces of the first buffer ring and the second buffer ring, thereby dispersing the impact force of the water flow, and solving the problems that there are some problems in the use of existing traditional desuperheating water throttling globe valves, and water hammer effect is likely to occur, which may cause damage to the pipeline system.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

A connecting pipe is arranged on the right side of the hollow ring. A connecting cylinder is connected and fixed to the top of the hollow ring. It also includes a pressure reducing mechanism. The pressure reducing mechanism includes a rotating ring rotatably connected between the connecting pipe and the hollow ring. A first buffer ring is fixedly connected to the right inner surface of the connecting pipe. A flow dividing cone is fixedly connected to the center of the left side of the first buffer ring. A second buffer ring is rotatably connected to the right side of the first buffer ring. <9000014>Furthermore, a connecting plate is fixedly connected to the outer surface of the second buffer ring. A second spring is fixedly connected to the bottom of the connecting plate. One end of the second spring away from the connecting plate is fixedly connected to a support plate.

[0007] Furthermore, the support plate is fixedly connected to the outer surface of the first buffer ring. One end of the connecting plate away from the second buffer ring is fixedly connected to a shifting ring. A second baffle is fixedly connected to the outer surface of the connecting pipe.

[0008] Furthermore, the number of the second baffles is four, and a baffle is provided at the bottom of each of the four second baffles, and the four baffles are rotatably connected to the outer wall of the connecting pipe.

[0009] Furthermore, a cut-off mechanism is provided on the inner wall of the hollow ring, and the cut-off mechanism comprises a cylinder which is sleeved and movably connected to the inner wall of the water pipe, the top of the cylinder is rotatably connected to a torsion ring, and the bottom of the cylinder is fixedly connected to a ball.

[0010] Furthermore, a circular hole is opened on the left side of the sphere, a first circular groove is opened at the bottom end of the outer wall of the cylinder, a second circular groove is opened on the inner surface of the first circular groove, and sleeves are fixedly connected to the left and right sides of the second circular groove close to the cylinder.

[0012] Furthermore, a retaining ring is fixedly connected to the middle end of the inner surface of the connecting tube, a plurality of inclined blocks are fixedly connected to the inner surface of the connecting tube, and a first baffle is fixedly connected to the inner surface of the connecting tube, and the number of the first baffles is four.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a pressure reducing mechanism. When cooling water is injected, the water flow impacts the left side of the first buffer ring and moves from the leaks on both sides of the first buffer ring. When the cooling water pressure is too high, in order to prevent the water hammer effect, the dial ring drives the connecting plate to be pressed down, and the dial connecting plate drives the rotating ring to rotate, and the connecting plate drives the second buffer ring to rotate at the same time. When the two leaks of the first buffer ring and the second buffer ring are blocked by each other, the water flow can only flow out from the arc holes on the surfaces of the first buffer ring and the second buffer ring when passing through, thereby dispersing the impact force of the water flow, preventing the water valve of the shut-off mechanism from being impacted for a long time, causing damage to the water valve, and improving the practicality of the device.

[0015] 2. In this utility model, by setting a cut-off mechanism, when controlling the water flow rate when desuperheating water passes through, rotate the torsion ring to drive the cylinder to rotate, the cylinder drives the spherical ball to rotate, and the spherical ball controls the angle between the circular hole and the water pipe according to the rotation angle, thereby achieving the control of the water flow rate. While rotating the torsion ring, the cylinder rotates to drive the sleeve to rotate, the sleeve drives the piston plate to rotate, and the piston plate drives the scraper to rotate. When the scraper rotates, it scrapes on the surface of the connecting pipe. When the scraper passes through the inclined block, the scraper is pushed back into the sleeve by the inclined block, and the piston plate squeezes the first spring. At this time, a vibration prompt will be received when rotating the torsion ring, reminding the staff of the current angle of the circular hole, so as to control the water flow rate. After passing through the inclined block, the scraper is reset by the first spring and then rotates and is blocked by the first baffle, which reminds the staff that the valve is in the closed state, thereby achieving the cut-off control of desuperheating water and improving the practicability of the device.

[0016] Of course, it is not necessary for any product implementing this utility model to achieve all the above-mentioned advantages simultaneously. Brief Description of the Drawings

[0036] A specific application of this embodiment is as follows: By providing a pressure reducing mechanism 6, when injecting desuperheating water, the water flow impacts on the left side of the first buffer ring 602 and moves through the leakage gaps on both sides of the first buffer ring 602. When the water pressure of the desuperheating water is too high, in order to prevent the occurrence of water hammer effect, the dial ring 608 drives the connecting plate 605 to press down, the connecting plate 605 drives the rotating ring 601 to rotate, and the connecting plate 605 drives the second buffer ring 604 to rotate at the same time.

[0037] By setting the cut-off mechanism 5, when desuperheating water passes through and the water flow rate needs to be controlled, rotate the torsion ring 502 to drive the cylinder 501 to rotate.

According to the rotation angle, the spherical ball 505 controls the angle between the circular hole 506 and the water pipe 2, so as to control the water flow rate. While rotating the torsion ring 502, the rotation of the cylinder 501 drives the sleeve 507 to rotate. The sleeve 507 drives the piston plate 509 to rotate. The piston plate 509 drives the scraper 510 to rotate. When the scraper 510 rotates, it scrapes on the surface of the connecting pipe 3. When the scraper 510 passes through the inclined block 513, the scraper 510 is pushed back into the sleeve 507 by the inclined block 513, and the piston plate 509 squeezes the first spring 508. At this time, when rotating the torsion ring 502, a vibration prompt will be received to remind the staff of the current angle of the circular hole 506, so as to control the water flow rate. After passing through the inclined block 513, the scraper 510 is reset by the first spring 508, and then rotates and is blocked by the first baffle 514, which reminds the staff that the valve is in the closed state, so as to cut off the desuperheating water and improve the practicability of the device.
