Description

Technical Field

[0001] The invention relates to the technical field of pipeline compensation, and in particular to a steam pipeline compensator. Background Art

[0002] At present, some steam pipes in thermal power plants that are frequently switched on and off often suffer from problems such as pipe fatigue, aging and fracture due to steam shock, pipe shrinkage and expansion. It is necessary to install compensators at some pipe sections to reduce shock and compensate for shrinkage and expansion. The existing square compensators are generally made of one to three pipes simmered into a "J" shape, mainly composed of a straight pipe section, two vertical pipe sections, two end pipe sections and other curved pipe connections, and their main function is to compensate for the thermal deformation of the pipeline.

[0003] The square compensator transports steam during operation. Due to thermal expansion and contraction inside the pipeline, the straight pipe section at the top is subjected to the greatest stress, which is prone to deformation and structural damage. Therefore, the present invention designs a steam pipeline compensator to solve the above problems. Summary of the invention

[0008] Further, both sides of the semicircular ring are fixedly connected with reset rods, the upper surface of the semicircular ring is fixedly connected with a spring rod, and the top of the spring rod is fixedly connected with a collar.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. This device limits the tilting of the straight pipe section through the spring belt and the auxiliary ring. When the straight pipe section tilts upward, the spring belt and the auxiliary ring transfer the stress of the straight pipe section to the fixed seat to prevent the straight pipe section from tilting upward to a large extent and causing damage to the straight pipe section. Through the rotation of the connecting rod and the elastic coordination of the rubber rod, the contraction of the vertical pipe sections on both sides can be limited, and the contraction pressure can be transferred to the pressure sensor. When the pressure is too high, it is convenient for outside personnel to repair and avoid the vertical pipe sections on both sides from shrinking too much to the middle, resulting in excessive deformation and damage, which further affects the compensation function of the subsequent compensator.

[0016] 2. This device allows the end pipe section of the compensator to be stressed through the slide and the limit rod, and can move an appropriate distance in the lateral direction. The setting of the extrusion spring can prevent the end pipe sections of the compensator from being damaged due to excessive movement when the end pipe sections on both sides are close to each other. At the same time, the cooperation between the semicircular ring and the slide allows the end pipe section to slide back and forth under the elasticity of the reset rod after being vibrated or shaken, which can reduce the vibration stress of the end pipe section during operation and avoid the compensator from vibrating for a long time and causing wear.

[0017] 3. This device drives the rotation of a small gas detector through a sliding table, and can perform air tightness detection on the connection between the two ends of the compensator and the external pipeline to avoid poor sealing at the connection, steam leakage, and energy waste and safety hazards when steam is transported inside the compensator.

[0018] 4. When the connection between the two ends of the compensator and the external pipeline is not sealed tightly, steam leaks from the connection and condenses into water in contact with the outside air, which may then drip into the pipeline or the external environment. The device drives the water-absorbing sponge to rotate in contact with the outer surface of the connection between the two ends of the compensator and the pipeline through the sliding table. It can wipe off part of the condensed water formed to avoid the leaked condensed water dripping into the pipeline system and causing subsequent impacts. It also prevents water from dripping onto the outer surface of the circular guide rail and causing damage to the circular guide rail.

[0019] 5. Through the reciprocating motion of the absorbent sponge, the device can make the water release plate squeeze the absorbent sponge after absorbing water, and then squeeze out the water inside the absorbent sponge, so that the squeezed absorbent sponge can be reused, avoiding the problem that the absorbent sponge cannot effectively absorb the condensed water at the connection after absorbing a certain degree of water.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0030] For example, see Figure 1-Figure 4 The present invention provides a technical solution for a steam pipe compensator: a steam pipe compensator, comprising a straight pipe section 1, an auxiliary mechanism 2 is fixedly connected to the outer surface of the straight pipe section 1, a first elbow 3 is fixedly connected to both ends of the straight pipe section 1, a vertical pipe section 4 is fixedly connected to the bottom end of the first elbow 3, a second elbow 5 is fixedly connected to the bottom end of the vertical pipe section 4, an end of the second elbow 5 away from the vertical pipe section 4 is fixedly connected to an end pipe section 6, and a detection mechanism 7 is fixedly connected to the outer surface of the end pipe section 6; the auxiliary mechanism 2 can limit the up and down movement of the straight pipe section 1 during the operation of the square compensator to avoid a large deformation of the straight pipe section 1 due to thermal expansion and contraction. The square compensator consists of a straight pipe section 1 and a first elbow 3, a vertical pipe section 4, a second elbow 5, and an end pipe section 6, and is used to transport hot steam inside.

[0031] First, when the square compensator is working, the up and down movement of the straight pipe section 1 of the compensator is limited by the auxiliary mechanism 2 to prevent the straight pipe section 1 from being deformed and damaged due to excessive force. At the same time, the contraction of the vertical pipe sections 4 at both ends of the straight pipe section 1 is limited to prevent the vertical pipe section 4 from being compressed inward due to thermal expansion and contraction, resulting in increased deformation and damage. The gas leakage detection is carried out at the connection between the two ends of the square compensator and the external pipeline through the detection mechanism 7 to prevent steam leakage from the connection.

[0032] The auxiliary mechanism 2 includes an auxiliary ring 21, the bottom end of the auxiliary ring 21 is fixedly connected with a spring belt 22, the bottom end of the spring belt 22 is fixedly connected with a fixing seat 23, both sides of the fixing seat 23 are fixedly connected with an anti-vibration component 24, the inner wall of the fixing seat 23 is fixedly connected with a pressure sensor 25, the side of the pressure sensor 25 close to the anti-vibration component 24 is fixedly connected with a rubber rod 26, the end of the rubber rod 26 away from the pressure sensor 25 is fixedly connected with a connecting rod 27, the inner wall of the connecting rod 27 is rotatably connected with a first rotating shaft 28, the side of the connecting rod 27 away from the first rotating shaft 28 is rotatably connected with a second rotating shaft 29, and the outer surface of the second rotating shaft 29 is fixedly connected with a soft ring 201. The auxiliary ring 21 is a ring of soft material, which can be deformed to a certain extent and limit the up and down movement of the straight pipe section 1, the spring belt 22 has an elastic stretching function, and the soft ring 201 is sleeved on the outer surface of the vertical pipe section 4 and has a deformation effect. The pressure sensor 25 can withstand a sufficiently large pressure.

[0033] The inner wall of the auxiliary ring 21 is fixedly connected to the outer surface of the straight pipe section 1 , both ends of the first rotating shaft 28 are fixedly connected to the outer surface of the fixing seat 23 , and the inner surface of the soft ring 201 is fixedly connected to the outer surface of the vertical pipe section 4 .

[0034] When the compensator is working, the internal pipeline transports steam, and the straight pipe section 1 is slightly warped upward due to thermal expansion and contraction. The auxiliary ring 21 limits the warping of the straight pipe section 1. When the auxiliary ring 21 is pulled upward by the straight pipe section 1, the spring belt 22 pulls the auxiliary ring 21 and the straight pipe section 1 to prevent the straight pipe section 1 from warping upward too much, causing damage to the straight pipe section 1 and affecting the continued use of the subsequent square compensator.

[0035] At the same time, when steam is transported inside the compensator, the riser sections 4 on both sides will shrink toward the middle due to thermal expansion and contraction. During the shrinkage process of the riser sections 4, the riser sections 4 drive the soft ring 201 to move toward the side close to the connecting rod 27, and push the upper end of the connecting rod 27 to rotate around the outer surface of the second rotating shaft 29 toward the side close to the spring belt 22. When the lower end of the connecting rod 27 rotates around the outer surface of the first rotating shaft 28 toward the side close to the spring belt 22, it will squeeze the bottom end of the rubber rod 26, and the rubber rod 26 will squeeze the outer surface of the pressure sensor 25 after being squeezed by the connecting rod 27. When the pressure sensor 25 feels that the pressure is too large and is about to exceed the critical value, it can transmit the signal to the outside staff to check and repair the square compensator. Through the rotation setting of the soft rings 201 on both sides and the connecting rod 27, the stress of the riser sections 4 on both sides can be transmitted through the connecting rod 27.

[0036] The anti-vibration component 24 includes a limiting rod 241, one end of the limiting rod 241 away from the fixed seat 23 is fixedly connected to a slide seat 242, a side of the slide seat 242 close to the limiting rod 241 is fixedly connected to an extrusion spring 243, and the inner surface of the slide seat 242 is slidably connected to a semicircular ring 244. The limiting rod 241 provides a limiting effect for the sliding of the slide seat 242, and the semicircular ring 244 can slide back and forth along the inner wall of the slide seat 242.

[0037] Both sides of the semicircular ring 244 are fixedly connected with a reset rod 245, the upper surface of the semicircular ring 244 is fixedly connected with a spring rod 246, and the top of the spring rod 246 is fixedly connected with a collar 247. The collar 247 is attached to the upper surface of the semicircular ring 244 under the elasticity of the spring rod 246.

[0038] One end of the limiting rod 241 away from the sliding seat 242 is fixedly connected to the side of the fixing seat 23 close to the connecting rod 27, one end of the extrusion spring 243 away from the sliding seat 242 is fixedly connected to the side of the fixing seat 23 close to the connecting rod 27, and one end of the reset rod 245 away from the semicircular ring 244 is fixedly connected to the inner wall of the sliding seat 242. The upper surface of the semicircular ring 244 is fixedly connected to the lower surface of the end pipe section 6.

[0039] When the square compensator is working, the end pipe sections 6 on both sides are subjected to stress and will move toward the side close to the fixed seat 23, driving the semicircular ring 244 and the slide 242 to move toward the side close to the fixed seat 23. The slide 242 will slide along the outer surface of the limiting rod 241 and squeeze the extrusion spring 243. The limiting rod 241 limits the movement of the slide 242, so that the slide 242 and the end pipe section 6 can move laterally along one side of the limiting axis. The elasticity of the extrusion spring 243 can be used to avoid the problem of excessive movement of the end pipe sections 6 on both sides, which may cause damage.

[0040] When the end pipe sections 6 on both sides move towards each other, the upper surface of the end pipe section 6 will be lifted to a certain extent. The lifted end pipe section 6 will squeeze the ring 247 and the spring rod 246, so that the spring rod 246 is stretched and the ring 247 will move upward a certain distance. The function of the spring rod 246 is to prevent the end pipe section 6 from moving upward too far, which will cause damage to the lifting.

[0041] When the square compensator expands due to heat or contracts due to cold, the square compensator will deform accordingly to absorb the change in length of the pipeline. This deformation process may cause the compensator to shake during operation. When the end pipe section 6 shakes, it will drive the semicircular ring 244 to slide back and forth along the inner wall of the slide 242 and squeeze the reset rod 245. The cooperation between the semicircular ring 244 and the slide 242 allows the end pipe section 6 to have the freedom to slide back and forth. The reset rod 245 has elasticity and reset functions, which can reduce the stress of the end pipe section 6 being subjected to shaking, and avoid the end pipe section 6 from shaking or oscillating, which may cause the compensator to fail to work normally later, thereby weakening its compensation function for thermal expansion and contraction of the pipeline.

[0042] For example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution for a steam pipeline compensator: on the basis of the first embodiment, the detection mechanism 7 comprises a sealing box 71, the inner wall of the sealing box 71 is fixedly connected with a connecting rod 72, the end of the connecting rod 72 away from the sealing box 71 is fixedly connected with a circular guide rail 73, the outer surface of the circular guide rail 73 is rotatably connected with a slide 74, the lower surface of the slide 74 is fixedly connected with a small gas detector 75, and the outer surface of the slide 74 is fixedly connected with a water absorbing component 76. The slide 74 can rotate along the outer surface of the circular guide rail 73 and drive the rotation of the small gas detector 75, and the small gas detector 75 can detect whether there is steam leakage at the connection between the two ends of the square compensator and the pipeline.

[0043] When the inside of the compensator is connected to the external pipeline to transport steam, the slide 74 can rotate along the outer surface of the circular guide rail 73 and drive the rotation of the small gas detector 75. When the small gas detector 75 rotates around the connection between the compensator and the external pipeline, it will perform an airtightness test on the connection to detect whether there is steam leakage.

[0044] The water absorbing component 76 includes a bent plate 761, a telescopic rod 762 is fixedly connected to the inner wall of the bent plate 761, a clamping plate 763 is fixedly connected to the output end of the telescopic rod 762, a water absorbing sponge 764 is fixedly connected to the inner surface of the clamping plate 763, and water squeezing components 765 are fixedly connected to both sides of the clamping plate 763. The water absorbing sponge 764 can absorb the condensed water that may exist at the connection between the two ends of the square compensator and the bent pipe.

[0045] When the slide 74 drives the small gas detector 75 to rotate to detect the air tightness of the pipeline connection, the slide 74 will also drive the rotation of the bent plate 761 and the telescopic rod 762. When the connection is not sealed tightly, the extension of the telescopic rod 762 will push the clamping plate 763 and the water-absorbing sponge 764 to move to the side close to the end pipe section 6 until the water-absorbing sponge 764 is attached to the outer surface of the end pipe section 6. If hot steam leaks out from the connection and encounters the cold air outside, the steam will condense into water when it encounters the cold air, and then leak from the connection, which may affect the pipeline system and the surrounding environment. During the rotation process, the sponge rod will fit the surface of the connection between the end pipe section 6 and the external pipeline, wipe off the condensed water formed, avoid the leakage of condensed water and affect the pipeline system, and prevent the condensed water from dripping onto the surface of the circular guide rail 73, causing damage to the circular guide rail 73 and causing it to be unable to operate subsequently.

[0046] The water squeezing component 765 includes a flexible rod 7651, a connection block 7652 is fixedly connected to the bottom end of the flexible rod 7651, a support shaft 7653 is rotatably connected to the inner wall of the connection block 7652, an elastic rope 7654 is fixedly connected to the side of the connection block 7652 away from the clamping plate 763, a limiting tube 7655 is slidably connected to the upper surface of the elastic rope 7654, a water discharge plate 7656 is fixedly connected to the side of the connection block 7652 close to the clamping plate 763, a through hole 7657 is provided on the upper surface of the water discharge plate 7656, and a water outlet pipe 7658 is fixedly connected to the side of the water discharge plate 7656 close to the connection block 7652. The limiting tube 7655 limits the elongation and sliding of the elastic rope 7654, a plurality of through holes 7657 are provided, and the elastic rope 7654 can pull the connection block 7652 to rotate around the outer surface of the support shaft 7653.

[0047] When there is steam leakage at the connection between the square compensator and the external pipe, and the water-absorbing sponge 764 is needed to wipe the condensed water, the telescopic rod 762 drives the water-absorbing sponge 764 to move toward the side close to the end pipe section 6. When the clamping plate 763 moves toward the side of the end pipe section 6, the elastic rope 7654 is stretched, and the connecting block 7652 is pulled around the outer surface of the support shaft 7653 to rotate toward the side close to the flexible rod 7651, and squeezes the bottom end of the flexible rod 7651. The connecting block 7652 also drives the rotation of the drain plate 7656. Therefore, after the clamping plate 763 moves a certain distance, the drain plate 7656 will completely break away from the lower surface of the water-absorbing sponge 764. At the same time, when the drain plate 7656 is opened at a certain angle, it will not touch the connection between the end pipe section 6 and the external pipe. The water-absorbing sponge 764 can absorb condensed water.

[0048] When the water-absorbing sponge 764 absorbs a certain amount of water and cannot absorb any more water, the slide 74 drives the water-absorbing sponge 764 and the telescopic movement to the top of the end pipe section 6, and the telescopic rod 762 contracts to drive the clamping plate 763 and the water-absorbing sponge 764 to move and reset to the side away from the end pipe section 6, and the clamping plate 763 moves to the side close to the curved plate 761. At this time, the elastic rope 7654 is loosened, gradually reducing the pulling force on the connecting block 7652, and the connecting block 7652 revolves around the supporting rod 7651 under the elasticity of the soft rod 7651. The support shaft 7653 rotates toward the side close to the clamping plate 763, and drives the drain plate 7656 to rotate toward the side close to the bottom of the water-absorbing sponge 764. The drain plates 7656 are symmetrically arranged on both sides of the clamping plate 763. Therefore, after the drain plates 7656 on both sides are reset, they can squeeze the water-absorbing sponge 764 to squeeze out the water inside the water-absorbing sponge 764. The squeezed water will enter the inside of the drain plate 7656 from the through hole 7657 on the surface of the drain plate 7656 to complete the collection of water.

[0049] When the water inside the water-absorbing sponge 764 is squeezed out, the slide 74 drives the drain plate 7656 and the water outlet pipe 7658 to rotate counterclockwise. During the rotation, the water inside the drain plate 7656 slides to the lowest point inside the drain plate 7656 and flows out from the inside of the water outlet pipe 7658. The port of the water outlet pipe 7658 is at a certain distance from the drain plate 7656, and the water flowing out of the water outlet pipe 7658 will not flow to the pipe connection and the outer surface of the circular guide rail 73.

[0050] The inner surface of the sealing box 71 is fixedly connected to the outer surface of the end pipe section 6, the side of the bent plate 761 close to the small gas detector 75 is fixedly connected to the outer surface of the slide 74, the end of the flexible rod 7651 away from the connecting block 7652 is fixedly connected to the side of the splint 763 close to the support shaft 7653, both ends of the support shaft 7653 are fixedly connected to the inner surface of the splint 763, the top end of the elastic rope 7654 is fixedly connected to the lower surface of the bent plate 761, and the top end of the limiting tube 7655 is fixedly connected to the lower surface of the bent plate 761.

[0051] The specific working process of the present invention is as follows:

[0052] First, the auxiliary mechanism 2 is used to limit the up and down movement of the straight pipe section 1 of the compensator to prevent the straight pipe section 1 from being deformed and damaged due to excessive force. At the same time, the contraction of the vertical pipe sections 4 at both ends of the straight pipe section 1 is limited by the rotation of the connecting rod 27 to prevent the vertical pipe sections 4 from being compressed inward due to thermal expansion and contraction, resulting in increased deformation and damage.

[0053] The cooperation between the inner semicircular ring 244 of the anti-vibration component 24 and the sliding seat 242 allows the end pipe section 6 to have the freedom to slide back and forth. The elasticity and reset function of the reset rod 245 are utilized to reduce the shaking stress on the end pipe section 6, thereby preventing the end pipe section 6 from shaking or oscillating for a long time in the working state, which may cause wear of the compensator.

[0054] By rotating the slide 74 inside the detection mechanism 7 and the small gas detector 75, the air tightness of the connection between the compensator and the external pipeline is tested to detect whether there is steam leakage.

[0055] The absorbent sponge 764 inside the absorbent component 76 is rotated in close contact with the connection between the compensator and the external pipeline to wipe off the condensed water, thereby preventing the hot steam from leaking out of the connection, condensing into water, and then dripping to the outside.

[0056] Finally, the water inside the water-absorbing sponge 764 is squeezed out by rotating the water-discharging plate 7656 inside the water-squeezing component 765, so as to prevent the water-absorbing sponge 764 from absorbing too much water and being unable to absorb water subsequently.
