Description

Technical Field

[0001] This utility model relates to the field of saturated steam supplement turbine technology, specifically a saturated steam supplement turbine with a pressure regulating mechanism. Background Technology

[0002] Steam turbines are one of the most important power units in power plants, mainly responsible for driving generators. However, during the operation of a steam turbine, the various components around its rotor are affected by huge rotational forces. Therefore, it is necessary to ensure proper levelness during installation to avoid affecting the normal operation of the rotor.

[0003] In existing technologies, most saturated steam turbines cannot accurately adjust according to real-time changes in steam pressure. They typically use a simple fixed pressure threshold control method. Once the steam pressure exceeds the range that the equipment can withstand, it is very easy to cause equipment failure. When the steam flow suddenly increases or the external operating conditions change suddenly, causing a sudden rise in pressure, the inability to adjust the pressure in time may cause the internal components of the turbine to be subjected to excessive pressure, resulting in damage. This not only affects the normal operation of the equipment, but also significantly increases the equipment maintenance cost and downtime. Moreover, the sealing effect is poor, making it difficult to effectively prevent steam leakage.

[0004] In view of this, we introduce a saturated steam supplement turbine with a pressure regulating mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a saturated steam supplement turbine with a pressure regulating mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a saturated steam supplement turbine with a pressure regulating mechanism, comprising: a base plate, pipes, and a pressure detector;

[0007] Support seats are provided on both sides of the top of the base plate. The support seats are fixedly installed to the base plate. There are two sets of support seats, and a steam turbine is connected between the two sets of support seats.

[0008] The pipe is located on one side of the steam turbine, the pipe passes through the support base, and through holes are opened at the upper and lower ends of the surface of the pipe. The through holes and the pipe are integrally formed.

[0009] The pressure detector is installed on the inner top wall of the pipeline. The model of the pressure detector 9 is: CWY300 digital pressure calibrator.

[0010] The pipeline is equipped with an adjustment mechanism. The threaded rod of the adjustment mechanism drives the sealing block to move inside the pipeline, releasing the seal on the through hole and allowing pressure to be discharged from the inside of the turbine and the pipeline, thus forming pressure regulation.

[0011] Preferably, the adjusting mechanism includes a turntable connected to one side of a threaded rod, the turntable and the threaded rod being fixedly disposed together, the sealing block being slidably disposed inside the pipe, the threaded rod being connected to one side of the sealing block, a bearing being sleeved on one side of the threaded rod and embedded inside the sealing block, the threaded rod passing through the pipe and connected to the turntable, a fixed cylinder being connected to one side of the inside of the pipe, the fixed cylinder being integrally formed with the pipe, an internal threaded portion being connected inside the fixed cylinder, the internal threaded portion being integrally formed with the fixed cylinder, an external threaded portion being connected to the surface of the threaded rod, the external threaded portion being integrally formed with the threaded rod, and the external threaded portion and the internal threaded portion being matched and screwed together.

[0012] Preferably, the upper and lower ends of the sealing block are respectively connected to sealing gaskets. The sealing gaskets are used to seal the through hole. The sealing gaskets can better seal the through hole and prevent external or internal gas from entering and escaping.

[0013] Preferably, a limiting rod is connected to one side of the sealing block, and one end of the limiting rod passes through the pipe and is connected to a limiting block. A spring is sleeved on the surface of the limiting rod. During the movement of the sealing block, the limiting rod slides inside the pipe. The limiting block at one end can prevent the limiting rod from coming out of the pipe. At the same time, the spring sleeved on the limiting rod plays a role in buffering and assisting in resetting.

[0015] Preferably, the leveling mechanism includes a leveling block connected to the surface of the positioning tube, and a leveling monitor is connected to the top of the leveling block. The leveling monitor on the leveling block connected to the surface of the positioning tube monitors the level status of the steam turbine in real time. If the leveling monitor detects that the steam turbine is tilted or otherwise not level, the steam turbine can be kept level through corresponding adjustment measures to ensure its stable operation.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) By setting up a pressure regulating mechanism, the pressure inside the steam turbine and the pipeline can be adjusted in a timely and effective manner according to the changes in the steam pressure inside the pipeline, so as to avoid damage to the equipment due to excessive pressure, and improve the safety and stability of equipment operation. The pressure regulation is achieved by rotating the turntable, which is simple in structure and easy to operate, reducing the difficulty and labor intensity of the operators.

[0018] (2) The sealing gaskets at the upper and lower ends of the sealing block can effectively seal the through hole, ensuring the sealing of the turbine and pipeline when pressure regulation is not required, reducing steam leakage and improving energy utilization efficiency.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a saturated steam supplement turbine with a pressure regulating mechanism, comprising: a base plate 1, and support seats 2 respectively provided on the top two sides of the base plate 1, the number of support seats 2 being two sets, and a turbine 3 connected between the two sets of support seats 2;

[0026] Pipeline 7 is located on one side of the steam turbine 3. Pipeline 7 passes through the support base 2. Through holes 8 are provided at the upper and lower ends of the surface of pipeline 7.

[0027] Pressure detector 9, which is installed on the inner top wall of pipe 7, is a CWY300 digital pressure calibrator.

[0028] An adjustment mechanism is provided inside the pipe 7. The threaded rod 15 of the adjustment mechanism drives the sealing block 10 to move inside the pipe 7, thereby releasing the seal on the through hole 8 and allowing pressure to be discharged from the turbine 3 and the inside of the pipe 7 to form pressure regulation.

[0029] The adjusting mechanism includes a turntable 17 connected to one side of a threaded rod 15, with the turntable 17 and the threaded rod 15 fixedly disposed. The sealing block 10 is slidably attached inside the pipe 7. The threaded rod 15 is connected to one side of the sealing block 10, and a bearing is sleeved on one side of the threaded rod 15. The bearing is embedded inside the sealing block 10. The threaded rod 15 passes through the pipe 7 and is connected to the turntable 17. A fixed cylinder 18 is connected to one side of the inside of the pipe 7. The fixed cylinder 18 and the pipe 7 are integrally formed. An internal threaded portion 20 is connected inside the fixed cylinder 18. The internal threaded portion 20 and the fixed cylinder 18 are integrally formed. An external threaded portion 16 is connected to the surface of the threaded rod 15. The external threaded portion 16 and the threaded rod 15 are integrally formed. The external threaded portion 16 and the internal threaded portion 20 are matched and screwed together.

[0030] The upper and lower ends of the sealing block 10 are respectively connected to sealing gaskets 19. The sealing gaskets 19 are used to seal the through hole 8. The sealing gaskets 19 can better seal the through hole 8 and prevent external or internal gas from entering and exiting.

[0031] One side of the sealing block 10 is connected to a limiting rod 11. One end of the limiting rod 11 passes through the pipe 7 and is connected to a limiting block 13. A spring 12 is sleeved on the surface of the limiting rod 11. During the movement of the sealing block 10, the limiting rod 11 slides in the pipe 7. The limiting block 13 at one end can prevent the limiting rod 11 from coming out of the pipe 7. At the same time, the spring 12 sleeved on the limiting rod 11 plays a role in buffering and assisting in resetting.

[0032] The surface of the steam turbine 3 is connected to a positioning tube 4, and the surface of the positioning tube 4 is provided with a horizontal adjustment mechanism.

[0033] The leveling mechanism includes a leveling block 5 connected to the surface of the positioning tube 4. A leveling monitor 6 is connected to the top of the leveling block 5. The leveling monitor 6 on the leveling block 5 connected to the surface of the positioning tube 4 monitors the level status of the steam turbine 3 in real time. If the leveling monitor 6 detects that the steam turbine 3 is tilted or not level, it can maintain the level of the steam turbine 3 through corresponding adjustment measures to ensure its stable operation.

[0034] Specifically, during operation, when the saturated steam turbine with pressure regulating mechanism is running, the pressure detector 9 inside the pipeline 7 monitors the steam pressure inside the pipeline 7 in real time. In the initial state, the sealing block 10 is tightly fitted to the through hole 8 on the pipeline 7 under the action of the sealing gasket 19, preventing steam from being discharged from the through hole 8. At this time, a relatively closed pressure environment is formed inside the turbine 3 and the pipeline 7. When the pressure detector 9 detects that the pressure inside the pipeline 7 exceeds the set threshold, pressure regulation is required. The operator rotates the turntable 17, which drives the threaded rod 15 connected to it to rotate. Since the external thread 16 on the surface of the threaded rod 15 matches and engages with the internal thread 20 inside the fixed cylinder 18, the threaded rod 15 will move axially while rotating. The movement of the threaded rod 15 drives the sealing block 10 to slide inside the pipeline 7, so that the sealing block 10 gradually moves away from the through hole 8, releasing the seal on the through hole 8. At this time, the steam inside the turbine 3 and the pipeline 7 can be discharged through the through hole 8, thereby reducing the internal pressure and achieving pressure regulation.

[0035] During the movement of the sealing block 10, the limiting rod 11 slides inside the pipe 7. The limiting block 13 at one end of the limiting rod 11 can prevent the limiting rod 11 from coming out of the pipe 7. At the same time, the spring 12 sleeved on the limiting rod 11 plays the role of buffering and assisting in reset.

[0036] During the operation of the steam turbine 3, the level monitoring instrument 6 on the level block 5 connected to the surface of the positioning tube 4 monitors the level status of the steam turbine 3 in real time. If the level monitoring instrument 6 detects that the steam turbine 3 is tilted or not level, it can maintain the level of the steam turbine 3 through corresponding adjustment measures to ensure its stable operation.

[0037] When the pressure inside the steam turbine 3 decreases and air needs to be replenished, the pressure inside the steam turbine 3 can be replenished through the through hole 8, making the operation more convenient.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
