AI Technical Summary
Existing gas drainers suffer from poor sealing due to gaps between the float and the inner wall, leading to potential gas leakage when the float tilts after drainage is completed.
The design incorporates a float with slots at its bottom, a limiting rod at the inner bottom of the leak-proof device, and a piston with a plug-in ring to enhance sealing, where the limiting rod limits the float's position to prevent tilting and a sealing ring plugs into the plug-in ring to seal the drain port, preventing gas leakage.
The solution effectively prevents gas leakage by ensuring the float remains in position after drainage, maintaining a complete seal through the limiting rod and sealing ring mechanism.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of anti-leakage devices for anti-leakage gas drainers, in particular to an anti-leakage device for anti-leakage gas drainers. Background Art
[0002] A gas drainer is a device used to collect and drain condensed water from gas pipes. Its main function is to prevent gas leakage and prevent malignant accidents such as fire, explosion and poisoning. The device consists of a drainer body, a leak prevention device and a heat preservation device.
[0003] In the prior art, most gas drainers are connected to the leakage device through pipes. When the condensed water reaches the leakage device, the water level in the cylinder rises to a certain position, the gravity of the float is less than the buoyancy, the float floats up, and the condensed water is discharged through the outlet. After the condensed water is discharged, the water level in the cylinder drops, the gravity of the float is greater than the buoyancy, the float drops, and the drain port is sealed by the piston.
[0004] However, in the prior art, there is a certain gap between the float and the inner wall of the anti-leakage device. When drainage is completed, the float may tilt, resulting in a gap between the piston and the drain port when the piston descends, causing the piston to have poor sealing properties. Utility Model Content

[0007] The limiting rods correspond to the slots one by one, and the limiting rods are inserted into the slots.
[0008] Preferably, a drain outlet is provided at the bottom of the gas drainer body, through which sewage can be discharged from the gas drainer body. A water inlet valve is provided at the top of the gas drainer body, and condensed water enters the gas drainer body from the water inlet valve. A gas pipeline interface is also provided at the top of the gas drainer body.
[0009] Preferably, a drain port is provided in the middle of the bottom of the leak-proof device, and a piston is connected to the middle of the bottom of the float, so that the piston completely blocks the drain port to prevent gas leakage.
[0010] Preferably, a plug-in ring is provided around the bottom of the piston, and a sealing ring is provided around the bottom of the piston. The sealing ring can be plugged into the plug-in ring to enhance the sealing performance of the piston.
[0011] Preferably, the limiting rod can limit the position of the buoy, and when the drainage is completed, the limiting rod limits the position of the buoy to prevent the buoy from tilting.
[0012] Preferably, a limiting block is provided on the top of the limiting rod, and the limiting block limits the rise of the buoy to prevent the buoy from rising too high, causing the limiting rod to be disengaged from the slot.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model proposes an anti-leakage device for an anti-leakage gas drainer. When the water level in the anti-leakage device rises to a certain position, the gravity of the float is less than the buoyancy, the float floats up, and condensed water is discharged through the drain port. After the condensed water is discharged, the water level in the anti-leakage device drops, the gravity of the float is greater than the buoyancy, the float drops, and a limiting rod in a slot provided at the bottom of the float begins to limit the float to prevent the float from tilting, resulting in a gap between a piston connected to the middle part of the bottom of the float and the drain port, resulting in incomplete sealing and gas leakage. At the same time, the sealing rings provided around the piston are plugged into the plug ring at the top of the plug ring to seal the drain port again. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1
[0023] See also Figure 1-Figure 3 The utility model provides a technical solution: the top side of the gas drainer body 1 is connected to a connecting pipe 5, the other end of the connecting pipe 5 is connected to a leak-proof device 6, a float 8 is arranged in the leak-proof device 6, slots 9 are arranged around the bottom of the float 8, a limiting rod 10 is arranged at the inner bottom of the leak-proof device 6, the limiting rod 10 corresponds to the slot 9 one by one, and the limiting rod 10 is inserted into the slot 9; the limiting rod 10 in the slot 9 opened at the bottom of 8 starts to limit the float 8 to prevent the float 8 from tilting.
[0024] Embodiment 2
[0025] On the basis of the first embodiment, a sewage outlet 2 is provided at the bottom of the gas drainer body 1, through which sewage can be discharged from the gas drainer body 1, a water inlet valve 3 is provided at the top of the gas drainer body 1, and condensed water enters the gas drainer body 1 from the water inlet valve 3, and a gas pipeline interface 4 is also provided at the top of the gas drainer body 1; a drainage outlet 7 is provided in the middle of the bottom of the leakage prevention device 6, and a piston 12 is connected to the middle of the bottom of the float 8, and the piston 12 completely blocks the drainage outlet 7 to prevent gas leakage; a plug-in ring 13 is provided around the bottom of the piston 12, and a sealing ring 14 is provided around the bottom of the piston 12, and the sealing ring 14 can be plugged into the plug-in ring 13 to deepen the sealing of the piston 12; at the same time, the sealing ring 14 provided around the piston 12 is plugged into the plug-in ring 13 at the top of the plug-in ring 13 to seal the drainage outlet 7 again.
[0026] Embodiment 3
[0027] On the basis of the second embodiment, the limit rod 10 can limit the buoy 8. When the drainage is completed, the limit rod 10 limits the buoy 8 to prevent the buoy 8 from tilting. A limit block 11 is provided on the top of the limit rod 10. The limit block 11 limits the rise of the buoy 8 to prevent the buoy 8 from rising too high, causing the limit rod 10 to be detached from the slot 9; so that the limit rod 10 can no longer limit the buoy 8.
[0028] There is a misalignment between the slot 9 and the limiting rod 10, which affects the normal descent of the buoy 8.
[0029] In actual use, when draining gas, first add condensed water into the gas drainer body 1 through the water inlet valve 3, then connect it to the gas pipeline through the gas pipeline interface 4, and the gas drainer body 1 starts to drain gas. When the pressure of the gas pipeline network is too high, exceeding or failing to reach the effective water seal height of the gas drainer body 1, the condensed water in the gas drainer body 1 enters the leak-proof device 6 through the connecting pipe 5. When the water level in the leak-proof device 6 rises to a certain position, the gravity of the float 8 is less than the buoyancy, and the float 8 floats. The condensed water is discharged through the drain port 7. After the condensed water is discharged, the water level in the leak-proof device 6 drops, the gravity of the float 8 is greater than the buoyancy, the float drops, and the limiting rod 10 in the slot 9 opened at the bottom of the float 8 begins to limit the float 8 to prevent the float 8 from tilting, resulting in a gap between the piston 12 connected to the middle part of the bottom of the float 8 and the drain port 7, resulting in incomplete sealing and gas leakage. At the same time, the sealing ring 14 arranged around the piston 12 is plugged into the plug-in ring 13 at the top of the plug-in ring 13 to seal the drain port 7 again.
