Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure pipe technology for gas compressors, and in particular to a pressure pipe draining device and a compressor unit. Background Technology
[0002] In gas compressors, the gas in the pipeline contains moisture, which accumulates in low-lying areas. Residual water from the compressor's water washing system and condensation in the bleed gas also flow into the pressure transmitter, causing moisture at the inlet of the pressure transmitter connected to the pressure transmitter and affecting the accuracy of pressure measurements. Typically, a drain port is installed at the lowest point of the pressure transmitter, opened for drainage. However, the moisture in the pressure transmitter moves along the pipe wall with the gas and is difficult to deposit and drain.
[0003] In the prior art, a draining device is disclosed, including a flange, a pressure tapping pipe fixedly installed inside the flange, and a housing fixedly installed outside the pressure tapping pipe. A liquid collection tank is opened at the bottom of the housing, and a drain outlet is opened at the middle of the bottom of the liquid collection tank. By setting up the liquid collection tank and the drain outlet, the liquid in the pressure tapping pipe will be deposited into the liquid collection tank due to gravity and discharged through the drain outlet, thus avoiding water accumulation in the pressure tapping pipe. However, when the pressure tapping pipe transmits gas, the gas will also escape from the drain outlet, causing the gas pressure in the pressure tapping pipe to drop, which will affect the normal operation of the pressure tapping pipe.

[0022] The beneficial effects of this utility model are:
[0023] This utility model provides a pressure-sensing pipe drainage device and a compressor unit. The pressure-sensing pipe drainage device is connected in series to the pressure-sensing pipe and includes a three-way body, a drainage component, and two connecting sleeves. The three-way body includes a first interface that is sealed to the first pressure-sensing pipe and a second interface that is sealed to the second pressure-sensing pipe. Each of the first and second interfaces is fitted with a connecting sleeve. The first connecting sleeve is detachably and fixedly connected to the first interface, and the second connecting sleeve is detachably and fixedly connected to the second interface. Each connecting sleeve has a limiting part that protrudes radially inward at the end away from the three-way body. The three-way body also includes a third interface.

The drainage component is detachably and fixedly connected to the third interface and has a conical drainage channel.
[0024] The three-way valve body is connected in series between the two pressure-sensing pipes, forming a complete gas flow channel. Gas enters from the first pressure-sensing pipe, passes through the three-way valve body, and exits from the second pressure-sensing pipe. When passing through the conical drainage channel of the drain device, liquid can be discharged from the conical drainage channel. This configuration not only allows water accumulated in the pressure-sensing pipes to be discharged through the conical drainage channel, but also, due to the presence of the conical drainage channel, the cross-sectional area of the gas flow gradually decreases as the gas passes through the pressure-sensing pipes, causing resistance to the gas flow. This prevents excessive gas from being discharged from the conical drainage channel and avoids pressure loss in the pressure-sensing pipes through the conical drainage channel, ensuring the normal operation of the pressure-sensing pipes while draining water.

[0037] This embodiment provides a pressure-sensing tube drainage device, wherein the pipeline is connected in series with the pressure-sensing tube, such as... Figures 1-4As shown, the device includes a three-way body 1, a drain component 3, and two connecting sleeves 2. The three-way body 1 includes a first interface 11 that is sealed to the first pressure-sensing tube and a second interface 12 that is sealed to the second pressure-sensing tube. Each of the first interface 11 and the second interface 12 is fitted with a connecting sleeve 2. The first connecting sleeve 2 is detachably and fixedly connected to the first interface 11, and the second connecting sleeve 2 is detachably and fixedly connected to the second interface 12. Each connecting sleeve 2 has a limiting part (not shown in the figure) protruding radially inward at the end away from the three-way body 1. The three-way body 1 also includes a third interface 13. Along the flow direction of the gas in the pressure-sensing tube, the third interface 13 is located between the first interface 11 and the second interface 12. The drain component 3 is detachably and fixedly connected to the third interface 13. The drain component 3 has a conical drain channel 312.
[0038] The three-way body 1 is connected in series between the two pressure-sensing pipes to form a complete gas flow channel. Gas enters from the first pressure-sensing pipe, passes through the three-way body 1, and exits from the second pressure-sensing pipe. When passing through the conical drainage channel 312 of the drainage component 3, liquid can be discharged from the conical drainage channel 312. This arrangement not only allows the liquid accumulated in the pressure-sensing pipe to be discharged through the conical drainage channel 312, but also, due to the presence of the conical drainage channel 312, the gas flow cross-sectional area gradually decreases as the gas passes through, causing resistance to the gas flow. This prevents excessive gas from being discharged from the conical drainage channel 312 and avoids pressure loss in the pressure-sensing pipe at the conical drainage channel 312, ensuring the normal operation of the pressure-sensing pipe while draining water. It should be noted that in this embodiment, the connecting sleeve 2 is a compression sleeve.
[0039] Optionally, such as Figure 1 and Figure 2 As shown, in this embodiment, the third interface 13 is located midway between the first interface 11 and the second interface 12, along the gas flow direction within the pressure-sensing tube. In other embodiments, the third interface 13 may be located between the first interface 11 and the second interface 12, closer to the first interface 11, or vice versa, along the gas flow direction within the pressure-sensing tube. No restrictions are imposed here. It should be noted that the third interface 13 being biased towards one of the first interface 11 and the second interface 12 is called "closer," not "midway" between the first interface 11 and the second interface 12.
[0040] Specifically, in this embodiment, the first connecting sleeve 2 is threadedly connected to the first interface 11. The threaded connection offers good adjustability. In other embodiments, the first connecting sleeve 2 can also be plugged into or snapped into the first interface 11, etc. No limitations are imposed here.
[0041] Specifically, in this embodiment, the second connecting sleeve 2 is threadedly connected to the second interface 12. The threaded connection offers good adjustability. In other embodiments, the second connecting sleeve 2 can also be plugged into or snapped into the second interface 12, etc. No limitations are imposed here.
[0042] It should be noted that in this embodiment, both the first interface 11 and the second interface 12 are M10 external thread interfaces, and the connecting sleeve 2 is an M10 internal thread ferrule sleeve. In other embodiments, both the first interface 11 and the second interface 12 are M12 external thread interfaces, and the connecting sleeve 2 is an M12 internal thread sleeve, etc. No restrictions are imposed here.
[0043] Specifically, in this embodiment, the liquid in the pressure tapping tube is water. In other embodiments, the liquid in the pressure tapping tube can be other liquids, such as chemical liquids, etc. No limitation is made here.
[0044] Furthermore, such as Figure 2 As shown, the conical drainage channel 312 is either a regular cone or an inverted cone in the direction of gas flow within the drainage component 3. Specifically, in this embodiment, the conical drainage channel 312 is a regular cone in the direction of gas flow within the drainage component 3. This effectively prevents water residue and accumulation at the conical drainage channel 312, ensuring a smooth and efficient drainage process. In other embodiments, the conical drainage channel 312 is an inverted cone in the direction of gas flow within the drainage component 3. No limitation is imposed here.
[0045] Furthermore, such as Figure 2 As shown, along the flow direction of the gas within the drain component 3, the drain component 3 is also provided with a liquid collection channel 311, which is located upstream of the conical drain channel 312 and is connected to the conical drain channel 312. The liquid collection channel 311 acts as a liquid storage and transfer station, collecting the water accumulated in the pressure tapping pipe and discharging it through the conical drain channel 312, ensuring that the water in the pressure tapping pipe can settle and preventing the water from flowing with the gas in the pressure tapping pipe.
[0046] Specifically, such as Figure 2 As shown, in this embodiment, the liquid collection channel 311 is connected to the smaller diameter end of the conical drainage channel 312. In other embodiments, the liquid collection channel 311 may also be connected to the larger diameter end of the conical drainage channel 312. No limitation is imposed here.
[0047] Optionally, such as Figure 2As shown, in this embodiment, the length L of the conical drainage channel 312 along the gas flow direction within the drainage component 3 is 8mm-12mm, and can be 8mm, 9mm, 10mm, 11mm, or 12mm, with 10mm being preferred in this embodiment. In other embodiments, the length L of the conical drainage channel 312 is not limited.
[0048] Furthermore, such as Figure 3 As shown, the smaller diameter end of the conical drainage channel 312 has a diameter 'a' of 0.8mm-1.2mm. This ensures the pressure of the gas inside the pressure-sensing tube. Optionally, in this embodiment, the smaller diameter end of the conical drainage channel 312 has a diameter 'a' of 1mm. This further ensures the pressure of the gas inside the pressure-sensing tube. In other embodiments, the smaller diameter end of the conical drainage channel 312 can also have a diameter 'a' of 0.8mm, 0.9mm, 1.1mm, or 1.2mm, etc. No limitation is imposed here.
[0049] Furthermore, such as Figure 2 As shown, along the flow direction of the gas within the drain component 3, the drain component 3 is also provided with a drainage channel 313, which is located downstream of the conical drain channel 312 and is connected to the conical drain channel 312. This arrangement prevents water in the drain pipe from being swept away by the airflow when discharged from the conical drain channel 312 with the gas, ensuring that the water discharged from the conical drain channel 312 drips onto the ground via the drainage channel 313, thus guiding the dripping of the water.
[0050] Optionally, in this embodiment, the length of the drainage channel 313 is greater than the length L of the conical drainage channel 312 along the gas flow direction within the drainage component 3. In other embodiments, the length of the drainage channel 313 may also be equal to the length L of the conical drainage channel 312, etc., along the gas flow direction within the drainage component 3. No limitations are imposed here.
[0051] Specifically, such as Figure 2 As shown, in this embodiment, the drainage channel 313 is connected to the larger diameter end of the conical drainage channel 312. In other embodiments, the drainage channel 313 may also be connected to the smaller diameter end of the conical drainage channel 312. No limitation is imposed here.
[0052] Optionally, such as Figure 2 As shown, in this embodiment, the drain component 3 is threadedly connected to the third interface 13. This facilitates the disassembly and assembly of the drain component 3 for maintenance and upkeep. In other embodiments, the drain component 3 can also be plugged into or snapped into the third interface 13, etc. No limitations are imposed here.
[0053] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown in the figure, the drain component 3 includes a drain body 31 and a disassembly / assembly part 32. The drain body 31 extends along the flow direction of the gas inside the drain component 3 and is annular. The drain body 31 is detachably and fixedly connected to the third interface 13. Along the radial direction of the drain body 31, the disassembly / assembly part 32 protrudes from the outer wall of the drain body 31 and is used for disassembling and assembling the drain body 31. The disassembly / assembly part 32 facilitates the removal or installation of the drain body 31 from the third interface 13.
[0054] Specifically, such as Figure 1 As shown, in this embodiment, the disassembly / reassembly part 32 is a regular hexagonal convex ring. In other embodiments, the disassembly / reassembly part 32 can also be a square convex ring, etc. As long as it can be turned with a wrench, there is no limitation.
[0055] Furthermore, the pressure-feeding tube drainage device also includes a sealing element (not shown in the figure) sleeved on the pressure-feeding tube. The limiting portion of the first connecting sleeve 2 and the first interface 11 can both abut against the sealing element, and / or, the limiting portion of the second connecting sleeve 2 and the second interface 12 can both abut against the sealing element. When the limiting portion of the first connecting sleeve 2 and the first interface 11 abut against the sealing element, and / or, the limiting portion of the second connecting sleeve 2 and the second interface 12 abut against the sealing element, the sealing element can fill the gap between the tee body 1 and the pressure-feeding tube, preventing gas leakage from the pressure-feeding tube at the connection point. It should be noted that in this embodiment, the sealing element is a sealing ring. In other embodiments, the sealing element can also be a sealing gasket or a sealing ring, etc. No limitation is made here.
[0056] Optionally, in this embodiment, two seals are provided. The limiting portion of the first connecting sleeve 2 and the first interface 11 both abut against the seal, while the limiting portion of the second connecting sleeve 2 and the second interface 12 both abut against the seal. In other embodiments, a single seal may be provided, with the limiting portion of the first connecting sleeve 2 and the first interface 11 both abutting against the seal, or the limiting portion of the second connecting sleeve 2 and the second interface 12 both abutting against the seal. No limitation is imposed here.
[0057] Optionally, in this embodiment, both the tee body 1 and the connecting sleeve 2 are made of stainless steel. In other embodiments, both the tee body 1 and the connecting sleeve 2 may be made of cast iron, or the tee body 1 may be made of stainless steel and the connecting sleeve 2 may be made of cast iron, etc. No limitations are imposed here.
[0058] Specifically, in this embodiment, both the tee body 1 and the connecting sleeve 2 are made of 316L stainless steel with a pressure resistance rating of 160 bar. In other embodiments, both the tee body 1 and the connecting sleeve 2 may be made of copper alloy, or the tee body 1 may be made of 316L stainless steel with a pressure resistance rating of 160 bar, and the connecting sleeve 2 may be made of copper alloy, etc. No limitations are imposed.
[0059] Optionally, in this embodiment, the drain component 3 is made of stainless steel. Using the same material as the tee body 1 and the connecting sleeve 2 improves the uniformity of the pressure-feeding drain device. In other embodiments, the drain component 3 may also be made of cast iron or aluminum alloy, etc. No limitations are imposed here.
[0060] This embodiment also provides a compressor unit, including a unit body and a pressure tap drain device, which is installed on the unit body. By using a conical drain channel 312, the gas pressure in the pressure tap is prevented from being released through the conical drain channel 312, ensuring the normal operation of the pressure tap while draining water, improving the operational stability of the compressor unit, and reducing the probability of unplanned shutdowns.
