Description

Technical Field

[0001] This invention relates to the field of compressor technology, specifically to an integrated booster and air lift compressor. Background Technology

[0002] The integrated booster and gas lift compressor is a core skid-mounted device for improving and restoring oil well production in the oil and gas extraction field. Its core function is to integrate gas boosting and gas lift functions to improve crude oil recovery efficiency and extraction economy. Natural gas associated with oil extraction is the most economical gas source and enters the compressor for boosting and gas lift. However, before entering the compressor, it needs to undergo gas-liquid separation and filtration purification. An additional natural gas filter dehydrator is connected in series with the integrated booster and gas lift compressor to perform gas-liquid separation and filtration purification of the natural gas.

[0003] When extracting natural gas oil wells rich in heavy hydrocarbons, heavy hydrocarbons, colloids, and asphaltene enter the liquid accumulation area in the form of tiny droplets. Due to the adhesion and surface tension of the droplets, the liquid does not flow. After a long time, the droplets solidify, adhere and bind together, forming viscous residues or even coking. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an integrated booster air lift compressor, including a device housing, a compressor unit fixedly connected to the inner wall of the device housing, a filter barrel fixedly connected to the inner wall of the device housing, an air outlet and an air inlet on the outer wall of the filter barrel, a filter assembly fixedly connected to the inner wall of the filter barrel, and further comprising: The flow diversion mechanism is fixedly installed at the bottom of the filter barrel; The drainage mechanism is fixedly installed on top of the drainage mechanism; Auxiliary mechanism, which is fixedly installed on the inner wall of the filter barrel; In this process, the natural gas from the wellhead is lifted by the compressor unit and then enters the filter barrel from the inlet. After the filter group filters out most of the droplets and solid impurities, it passes through the filter screen to filter out the tiny droplets. The clean natural gas then enters the compressor unit through the outlet and is compressed by the compressor unit before being used for gas lifting again.

[0005] Preferably, the traffic diversion mechanism includes: The flow guiding component is fixedly installed at the bottom of the filter canister; There are two floating components, both of which are rotatably mounted on the inner wall of the flow guide component. The liquid left by the natural gas after passing through the filtration group flows into the guide assembly through the floating component, and then is discharged to the outside of the device through the delivery pipeline.

[0006] Preferably, the leakage mechanism includes: There are two spring assemblies, both of which are fixedly installed on the inner wall of the flow guide assembly. There are two spring clip assemblies, and the two spring clip assemblies are fixedly connected to the outer wall of the floating assembly. The floating component is affected by the liquid accumulation inside the filter tank, which controls the up-and-down movement of the spring component and also affects the state of the spring assembly.

[0007] Preferably, the auxiliary mechanism includes: There are two blocking components, both of which are fixedly installed on the inner wall of the flow guiding component. The guide component is fixedly installed on the inner wall of the filter barrel; The blocking component is used to restrict the movement of the spring assembly, and the guiding component is used to guide the flow.

[0008] Preferably, the flow guiding component includes a water collection tank fixedly connected to the outer wall of the filter bucket, with two water pipes connected to the top of the water collection tank, and several fixing rods fixedly connected to the inner wall of the filter bucket. Two water pipes are connected to the filter bucket, and four fixed rods are provided. Each pair of fixed rods forms a group, and each group of fixed rods is adapted to the water pipes.

[0009] Preferably, the floating assembly includes two connecting rods 1 rotatably connected to the outer wall of the fixed rod, each of the two connecting rods 1 having a float fixedly connected to its outer wall, and each of the two connecting rods 1 having a connecting rod 2 rotatably connected to its side away from the float. The two connecting rods are mirror images of each other, and the two floats are made of lightweight foam. The distance between the floats and the fixed rod is less than the distance between the connecting rod and the fixed rod.

[0010] Preferably, the spring assembly includes a sleeve 1 fixedly connected to the bottom of the connecting rod 2, a sleeve 2 slidably connected to the outer wall of the sleeve 1, and a baffle ring fixedly connected to the outer wall of the sleeve 2; Among them, the diameter of sleeve two is larger than that of sleeve one, and a sealing ring is provided between sleeve one and sleeve two.

[0011] Preferably, the spring assembly includes a spring fixedly connected to the inner wall of sleeve one, and a limit plate fixedly connected to the bottom of sleeve two; The side of the spring away from the sleeve is fixedly connected to the limiting plate, and the outer side of the limiting plate is provided with an inclined surface. The spring is initially in a free state.

[0012] Preferably, the blocking component includes several spring pieces fixedly connected to the inner wall of the water pipe, several blocking blocks fixedly connected to the inner wall of the water pipe, and a sealing ring fixedly connected to the inner wall of the filter bucket. Among them, several spring pieces are arranged in a circular array, the spring pieces are initially in a free state, several blocking blocks are arranged in a circular array, and the sealing ring is made of rubber.

[0013] The guiding components include several guide ribs that are fixedly connected to the inner wall of the filter barrel; Among them, the guide ribs are grouped into groups of five, with the guide ribs on the side closer to the second connecting rod being close to each other, and the side farther away from the second connecting rod being far apart from each other.

[0014] The present invention has the following beneficial effects: (1) This invention utilizes the gradual rise of the liquid level in the accumulation zone. At this time, the float is affected by buoyancy and rises, causing the sleeve to move downwards. When the liquid level in the accumulation zone rises to a certain height, the float floats to a certain height, the limiting plate breaks through the spring plate's restriction, and the flow-blocking ring quickly separates from the water pipe. The accumulated liquid above can flow out through the gap between the flow-blocking ring and the water pipe, and then flow into the collection tank. After a portion of the liquid in the accumulation zone flows out, the liquid level in the accumulation zone drops, the float moves downwards, causing sleeve one and sleeve two to move upwards. When the liquid level drops to a certain height, the limiting plate breaks through the spring plate's restriction, and the flow-blocking ring can... The device is in close contact with the water pipe, preventing the liquid in the accumulating area from flowing out until the liquid level in the accumulating area reaches a certain height. Once a certain liquid level is reached, the device can quickly drain the water, thus achieving rapid and frequent drainage. This keeps the liquid in the accumulating area constantly agitated. Through the application of the above components, the problem of heavy hydrocarbons, colloids, and asphaltene entering the accumulating area as tiny droplets during the extraction of natural gas oil wells rich in heavy hydrocarbons is effectively prevented. Due to the adhesion and surface tension of the droplets, the liquid does not flow. Over a long period of time, the droplets solidify, adhere, and form viscous residues or even coking.

[0015] (2) When draining water, the present invention first drains the liquid and solid impurities near the water pipe and the upper surface of the liquid accumulation area. Impurities and heavier droplets close to the inner wall of the filter bucket and far from the water pipe are difficult to flow. The inner wall of the filter bucket is not horizontal. The inner wall of the filter bucket tends to tilt towards the water pipe. The two water pipes are tilted towards the water pipe on both sides. The middle part of the inner wall of the filter bucket between the two water pipes is raised, so that the liquid in the liquid accumulation area gathers above the water pipe and does not accumulate at the raised part of the inner wall of the filter bucket. At the same time, the guide ribs are set on the inner wall of the filter bucket. The liquid and solid impurities can flow along the inclined surface and along the guide ribs to the liquid accumulation area, so that the liquid far from the water pipe is more easily drained. Through the application of the above components, the problem of the droplets and solid impurities far from the water pipe being difficult to drain when draining water is effectively prevented.

[0016] (3) In this invention, a liquid seal is formed above the baffle ring in the liquid area. There is a certain air pressure on the inner wall of the filter bucket. The air pressure fluctuation will cause the baffle ring to move up and down. By setting the sealing ring, when there is no drainage, the sealing ring is in close contact with the sleeve, so the liquid gathers above the sealing ring. When drainage begins, the sleeve separates from the sealing ring, and the liquid can flow out through the sealing ring. When the liquid level drops, the sleeve does not contact the sealing ring when the baffle ring does not contact the water pipe. When the baffle ring contacts the water pipe, the sleeve can also contact the sealing ring, so the liquid cannot be drained. At this time, the liquid between the sealing ring and the baffle ring cannot be filled. After the liquid seal is formed above the sealing ring, the gas pressure fluctuation presses on the liquid seal and then transmits to the sealing ring. The sealing ring has a certain elasticity. The pressure fluctuation generated by the gas pressure fluctuation is converted into the force of the sealing ring. Through the application of the above components, the problem of the baffle ring moving up and down due to the pressure fluctuation inside the filter bucket after the liquid seal is formed above the water pipe is effectively prevented.

[0017] (4) This invention utilizes the feature of the above-mentioned equipment to drain water when the liquid accumulation area reaches a certain height. When the limiting plate disengages from the spring, the limiting plate is located below the spring. At this time, the spring quickly releases the elastic potential energy accumulated before, and the limiting plate drives the sleeve to move downward quickly. At this time, the float will disengage from the liquid surface at the liquid accumulation point, and the float will quickly rise to a very high height. At this time, the liquid surface at the liquid accumulation point needs to reach a very high height to trigger the float, making it difficult to return to its original position. By setting a blocking block, when the limiting plate drives the sleeve to move downward quickly, it is blocked by the blocking block, and the limiting plate is difficult to rise to the height at which the float is difficult to reset. Through the application of the above components, the problem of the float rising to a height at which it is difficult to reset due to the influence of the spring when drainage begins is effectively prevented, which would cause the device to be difficult to work.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-6 This invention relates to an integrated booster air lift compressor, comprising a housing 13, a compressor unit 14 fixedly connected to the inner wall of the housing 13, a filter barrel 15 fixedly connected to the inner wall of the housing 13, an air outlet 16 and an air inlet 17 on the outer wall of the filter barrel 15, and a filter assembly 18 fixedly connected to the inner wall of the filter barrel 15. The invention also includes: The flow diversion mechanism 1 is fixedly installed at the bottom of the filter barrel 15; Drainage mechanism 2 is fixedly installed on top of drainage mechanism 1; Auxiliary mechanism 3 is fixedly installed on the inner wall of filter barrel 15; In this process, the natural gas from the wellhead is lifted by the compressor unit 14 and then enters the filter barrel 15 through the inlet 17. After passing through the filter group 18 to remove most of the droplets and solid impurities, it passes through the filter screen 19 to remove the tiny droplets. The clean natural gas then enters the compressor unit 14 through the outlet 16 and is compressed by the compressor unit 14 before being used for gas lifting again.

[0023] Traffic generation agency 1 includes: The flow guiding component 11 is fixedly installed at the bottom of the filter barrel 15; There are two floating components 12, and both floating components 12 are rotatably disposed on the inner wall of the flow guiding component 11.

[0024] The leakage mechanism 2 includes: Spring assembly 21, two spring assemblies 21 are provided, and both spring assemblies 21 are fixedly installed on the inner wall of the flow guide assembly 11; There are two spring clip assemblies 22, and the two spring clip assemblies 22 are fixedly connected to the outer wall of the floating assembly 12 respectively. The floating component 12 is affected by the liquid accumulation inside the filter tank 15, which controls the up and down movement of the spring component 21 and also affects the state of the spring component 22.

[0025] Auxiliary mechanism 3 includes: There are two blocking components 31, and both blocking components 31 are fixedly installed on the inner wall of the flow guiding component 11. The guide component 32 is fixedly installed on the inner wall of the filter barrel 15; The blocking component 31 is used to restrict the movement of the spring component 21, and the guiding component 32 is used to guide the flow.

[0026] Example 2, please refer to Figures 4-11 The present invention is a booster air lift integrated compressor. Based on Example 1, the flow guiding component 11 includes a water collection tank 111 fixedly connected to the outer wall of the filter barrel 15. Two water pipes 112 are connected to the top of the water collection tank 111. Several fixing rods 113 are fixedly connected to the inner wall of the filter barrel 15. Two water pipes 112 are connected to the filter bucket 15. Four fixed rods 113 are provided, with each pair of fixed rods 113 forming a group. Each group of fixed rods 113 is adapted to the water pipes 112.

[0027] The floating assembly 12 includes two connecting rods 121 rotatably connected to the outer wall of the fixed rod 113. A float 122 is fixedly connected to the outer wall of each of the two connecting rods 121. A connecting rod 123 is rotatably connected to the side of each of the two connecting rods 121 away from the float 122. Among them, the two connecting rods 121 are arranged in a mirror image, the two floats 122 are made of lightweight foam, and the distance between the floats 122 and the fixed rod 113 is less than the distance between the connecting rod 123 and the fixed rod 113.

[0028] Spring assembly 21 includes a sleeve 211 fixedly connected to the bottom of connecting rod 2 123, a sleeve 212 slidably connected to the outer wall of sleeve 211, and a baffle ring 213 fixedly connected to the outer wall of sleeve 212. Among them, the diameter of sleeve 212 is larger than that of sleeve 1 211, and a sealing ring is provided between sleeve 1 211 and sleeve 212.

[0029] The spring assembly 22 includes a spring 221 fixedly connected to the inner wall of sleeve one 211, and a limit plate 222 fixedly connected to the bottom of sleeve two 212; Among them, the side of spring 221 away from sleeve 211 is fixedly connected to limit plate 222, and the outer side of limit plate 222 is provided with an inclined surface. The initial state of spring 221 is free state.

[0030] The blocking component 31 includes several spring pieces 311 fixedly connected to the inner wall of the water pipe 112, several blocking blocks 312 fixedly connected to the inner wall of the water pipe 112, and a sealing ring 313 fixedly connected to the inner wall of the filter bucket 15. Among them, several spring pieces 311 are arranged in a circular array, the spring pieces 311 are initially in a free state, several blocking blocks 312 are arranged in a circular array, and the sealing ring 313 is made of rubber. After the impurity-rich natural gas is filtered, the remaining droplets flow to the bottom of the filter bucket 15, forming a liquid accumulation area. The float 122 floats on the surface of this accumulation area. As the liquid level gradually rises, the float 122, influenced by buoyancy, also rises. At this time, connecting rod 121 rotates around the connection point between the fixed rod 113 and connecting rod 121. Because the distance from the float 122 to the fixed rod 113 is less than the distance from the connecting rod 123 to the fixed rod 113, when the float 122 rises a smaller distance, connecting rod 123 can descend a larger distance. When connecting rod 123 moves downward, it causes sleeve 211 to move downward. Due to the limitation... The limiting plate 222 is restricted by the spring piece 311, causing the spring 221 to transition from a free state to a compressed state. At this time, the downward movement speed of sleeve one 211 is greater than that of sleeve two 212. As the connecting rod two 123 gradually moves downward, the elastic potential energy of the spring 221 continuously accumulates, and the spring piece 311 undergoes a downward deformation, transitioning from a free state to a compressed state. At this time, the elastic potential energy of the spring 221 is less than the sum of the elastic potential energies of the six spring pieces 311. The limiting plate 222 remains above the spring pieces 311. When the liquid level in the accumulation area rises to a certain height, the float 122 floats to a certain height. At this time, the elastic potential energy accumulated by the spring 221 is greater than the elastic potential energy generated by the six spring pieces 311. When the limiting plate 222 breaks through the restriction of the spring 311, the elastic potential energy of the spring 221 is rapidly released, changing from a compressed state to a free state. The spring 311 changes from a compressed state to a free state, and the baffle ring 213 quickly disengages from the water pipe 112. The liquid above can flow out from the gap between the baffle ring 213 and the water pipe 112, and then flow into the water collection tank 111. After a portion of the liquid in the accumulation area flows out, the liquid level in the accumulation area drops, the float 122 moves down, and the connecting rod 123 moves up, driving the sleeve 1 211 and the sleeve 2 212 to move up. At this time, the spring 311 will first detect the inclined surface on the limiting plate 222, so the sleeve 2 212 cannot connect with the water pipe 112. 2. Despite close contact, the liquid will still flow out from the gap between the baffle ring 213 and the water pipe 112. As the liquid level continues to drop, the connecting rod 213 continues to move upward. The limiting plate 222 causes the spring 311 to deform upward. The spring 311 changes from a free state to a compressed state. When the liquid level drops to a certain height, the limiting plate 222 breaks through the limitation of the spring 311, and the baffle ring 213 can make close contact with the water pipe 112, so that the liquid in the accumulation area cannot flow out until the liquid level in the accumulation area reaches a certain height next time. This allows the device to drain water quickly after reaching a certain liquid level, thereby achieving rapid and frequent drainage, and causing the liquid in the accumulation area to be continuously agitated. When the limiting plate 222 drives the sleeve 211 to move downwards rapidly, it is blocked by the blocking block 312, making it difficult for the limiting plate 222 to rise to the height where the float 122 cannot be reset.

[0031] The guide component 32 includes several guide ribs 321 that are fixedly connected to the inner wall of the filter barrel 15; Among them, the five guide ribs 321 are grouped together, with the side of the guide ribs 321 closer to the connecting rod 2 123 and the side away from the connecting rod 2 123 moving away from each other; During drainage, first drain the liquid and solid impurities near the water pipe 112 and the upper surface of the liquid accumulation area. Impurities and heavier droplets close to the inner wall of the filter bucket 15 and farther from the water pipe 112 are difficult to flow. The inner wall of the filter bucket 15 is not horizontal; it tends to slope towards the water pipe 112. The two sides of the two water pipes 112 slope towards the water pipe 112, and the middle part of the inner wall of the filter bucket 15 between the two water pipes 112 is raised, causing liquid to accumulate in the liquid accumulation area. No liquid accumulation occurs at the protrusion on the inner wall of the filter bucket 15 above the water pipe 112. At the same time, guide ribs 321 are provided on the inner wall of the filter bucket 15. The guide ribs 321 are close to each other on the side near the connecting rod 123 and far away from each other on the side away from the connecting rod 123. By setting the inclined surface and the guide ribs 321, liquid and solid impurities can flow along the inclined surface and along the guide ribs 321 to the liquid accumulation area, so that the liquid that is far away from the water pipe 112 can be discharged more easily.

[0032] One specific application of this embodiment is as follows: When in use, the wellhead natural gas is lifted by the compressor unit 14 and enters the filter tank 15 from the inlet 17. After passing through the filter group 18 to filter out most of the droplets and solid impurities, it passes through the filter screen 19 to filter out the tiny droplets. Then, the clean natural gas enters the compressor unit 14 through the outlet 16 and is compressed by the compressor unit 14 and used for gas lifting again.

[0033] When the impurity-rich natural gas is filtered, the remaining droplets flow to the bottom of the filter bucket 15, forming a liquid accumulation area. The float 122 floats on the surface of this accumulation area. As the liquid level gradually rises, the float 122, influenced by buoyancy, also rises. At this time, connecting rod 121 rotates around the connection point between the fixed rod 113 and connecting rod 121. Because the distance from the float 122 to the fixed rod 113 is less than the distance from the connecting rod 123 to the fixed rod 113, when the float 122 rises a smaller distance, connecting rod 123 can descend a larger distance. As connecting rod 123 moves downward, it causes sleeve 211 to move downward. Because the limiting plate 222 is restricted by the spring 311, the spring 221... The process transitions from a free state to a compressed state. At this point, the downward speed of sleeve 1 211 is greater than that of sleeve 212. As connecting rod 2 123 gradually moves downward, the elastic potential energy of spring 221 continuously accumulates, and the spring piece 311 undergoes a downward deformation, transitioning from a free state to a compressed state. At this time, the elastic potential energy of spring 221 is less than the sum of the elastic potential energies of the six spring pieces 311. The limiting plate 222 remains above the spring pieces 311. When the liquid level in the accumulation area rises to a certain height, the float 122 floats to a certain height. At this time, the elastic potential energy accumulated by spring 221 is greater than the sum of the elastic potential energies generated by the six spring pieces 311. The limiting plate 222 breaks through the restriction of the spring pieces 311, and the elastic potential energy of spring 221 is rapidly released, changing from a compressed state to a free state. As the sleeve 212 transitions from a compressed state to a free state, it quickly detaches from the water pipe 112. The accumulated liquid above can then flow out through the gap between the sleeve 212 and the water pipe 112, subsequently flowing into the collection tank 111. After some liquid has flowed out of the accumulation area, the liquid level drops, causing the float 122 to move downwards and the connecting rod 123 to move upwards, pulling the sleeves 211 and 212 upwards. At this point, the spring 311 will first detect the inclined surface on the limiting plate 222, preventing the sleeve 212 from making tight contact with the water pipe 112. The liquid will still flow out through the gap between the baffle ring 213 and the water pipe 112. As the liquid level continues to drop, the connecting rod 123 continues to move upwards, and the limiting plate 222 causes the spring 311 to deform upwards. The liquid transitions from a free state to a compressed state. When the liquid level drops to a certain height, the limiting plate 222 breaks through the restriction of the spring 311, and the flow-blocking ring 213 can make close contact with the water pipe 112, thus preventing the liquid in the accumulation zone from flowing out until the liquid level in the accumulation zone reaches a certain height again. This allows the device to drain water quickly after reaching a certain liquid level, thus achieving rapid and frequent drainage. This keeps the liquid in the accumulation zone constantly agitated. Through the application of the above components, it effectively prevents heavy hydrocarbons, colloids, and asphaltene from entering the accumulation zone in the form of tiny droplets when mining natural gas oil wells rich in heavy hydrocarbons. Due to the adhesion and surface tension of the droplets, the liquid does not flow. After a long time, the droplets solidify, adhere, and form viscous residues or even coking.

[0034] Taking advantage of the continuous agitation of the liquid in the accumulation zone of the aforementioned equipment, during drainage, the liquid and solid impurities near the water pipe 112 and the upper surface of the accumulation zone are drained first. Impurities and heavier droplets close to the inner wall of the filter bucket 15 and farther from the water pipe 112 are difficult to flow. The inner wall of the filter bucket 15 is not horizontal; it tends to slope towards the water pipe 112. The two sides of the two water pipes 112 slope towards the water pipe 112, and the middle part of the inner wall of the filter bucket 15 between the two water pipes 112 is raised, causing the liquid in the accumulation zone to gather above the water pipe 112 in the filter bucket. The inner wall protrusion of filter 15 does not accumulate liquid. At the same time, guide ribs 321 are provided on the inner wall of filter 15. The guide ribs 321 are close to each other on the side near the connecting rod 123 and far away from each other on the side away from the connecting rod 123. By setting the inclined surface and the guide ribs 321, liquid and solid impurities can flow along the inclined surface and the guide ribs 321 to the liquid accumulation area, so that liquids farther away from the water pipe 112 can be discharged more easily. Through the application of the above components, the problem of droplets and solid impurities far away from the water pipe 112 being difficult to be discharged when draining is effectively prevented.

[0035] Utilizing the characteristic of the aforementioned equipment where liquid accumulates above the water pipe 112 in the accumulation area, a liquid seal is formed above the baffle ring 213. A certain air pressure exists on the inner wall of the filter tank 15; pressure fluctuations cause the baffle ring 213 to move up and down. By setting a sealing ring 313, when no drainage is being performed, the sealing ring 313 is in close contact with the sleeve 211, thus the liquid accumulates above the sealing ring 313. When drainage begins, the sleeve 211 disengages from the sealing ring 313, allowing the liquid to flow out through the sealing ring 313. When the liquid level drops, the baffle ring 213 is no longer in contact with the water pipe 112, and the sleeve 211 is also no longer in contact with the sealing ring 313. When the flow ring 213 contacts the water pipe 112, the sleeve 211 can also contact the sealing ring 313, so the liquid cannot be drained. At this time, the liquid between the sealing ring 313 and the baffle ring 213 cannot be filled. After the liquid above the sealing ring 313 forms a liquid seal, the gas pressure fluctuation presses on the liquid seal and is then transmitted to the sealing ring 313. The sealing ring 313 has a certain elasticity. The pressure fluctuation generated by the gas pressure fluctuation is converted into the force of the deformation of the sealing ring 313. Through the application of the above components, the problem of the baffle ring 213 moving up and down due to the pressure fluctuation inside the filter bucket 15 after the liquid accumulation area forms a liquid seal above the water pipe 112 is effectively prevented.

[0036] Taking advantage of the aforementioned device's ability to drain liquid from a certain height, when the limiting plate 222 disengages from the spring 311, it is positioned below the spring 311. At this time, the spring 221 rapidly releases its accumulated elastic potential energy, causing the limiting plate 222 to drive the sleeve 211 to move rapidly downwards. The float 122 then disengages from the liquid surface at the drainage point, causing it to rise rapidly to a very high height. Since the liquid surface at the drainage point needs to reach such a high height to trigger the float 122, it is difficult for it to return to its original position. By setting a blocking block 312, when the limiting plate 222 drives the sleeve 211 to move rapidly downwards, the blocking block 312 prevents the limiting plate 222 from rising to a height where the float 122 cannot return to its original position. The application of these components effectively prevents the float 122 from rising to a height where it cannot return to its original position due to the influence of the spring 221 when drainage begins, thus preventing the device from malfunctioning.
