Description

Technical Field

[0001] This utility model relates to the field of drainage device application technology, and in particular to a novel floating drainage device. Background Technology

[0002] Floating drainers are widely used drainage devices in the air circuit connections of equipment. For long-distance air pipe connections, air compressors typically pressurize the inside of the pipe to maintain balanced air pressure. While the air compressor has some drying capacity for the pressurized gas during continuous pressurization, a small amount of moisture still remains. In long-distance pipes, this moisture condenses into droplets. Moisture residue at the connection point is unacceptable as it can corrode the pipes and the connection point. Although drainers are currently installed at intervals within the pipes, conventional drainers have the following technical problems: during drainage, a large portion of the gas is also discharged, leading to excessively high compressor operating load and wasted electricity; furthermore, their complex structure makes them prone to drainage problems and blockages after a period of use. Therefore, a simple floating drainer is urgently needed to solve these technical issues. Utility Model Content

The float lever 1011 is laterally connected to a valve core 102. A piston 202 is disposed inside the inner cavity 2, and a piston spring 201 is disposed inside the piston 202. A spring extension rod 2011 is disposed at the lower end of the piston spring 201, and a piston through hole 2023 is connected to the lower part of the spring extension rod 2011. The lower part of the piston through hole 2023 is connected to a piston lower port 2021. The connector 3 is connected to the lower side of the inner cavity 2. By utilizing the floating effect of external water on the float housing 1, and coordinating the air pressure difference formed by the gap between the float lever 1, the spring extension rod 2011, and the piston through hole 2023, reciprocating drainage is achieved.

[0028] A lever fixing seat 101 is provided on one side of the float housing 1. The lever fixing seat 101 is used to limit the stroke of the float lever 1011. A through hole 104 is provided between the valve core seal 103 and the inner cavity 2. The valve core seal 103 is used to seal the through hole 104 in the upper part of the inner cavity.

[0029] Multiple inner cavity reinforcing fixing blocks 206 are provided on the lower outer side of the inner cavity 2. Multiple rotating fixing teeth 207 are arranged around the lower inner side of the inner cavity reinforcing fixing blocks 206. The rotating fixing teeth 207 are engaged with the upper part of the connector 3 to achieve a fixed connection. The rotating fixing teeth 207 are arranged at intervals.

[0030] The upper part of the connector 3 is provided with multiple positioning connecting blocks 301, and the lower inner side of the positioning connecting block 301 is provided with a connecting embedding cavity 3011. The lower circumferential side of the rotating fixing tooth 207 is provided with a fixing tooth retaining strip 2071. The inner cavity 2 and the connector 3 are fixedly connected by the fixing tooth retaining strip 2071 and the connecting embedding cavity 3011 rotating and engaging with each other.

[0031] The piston 202 is provided with a sealing embedding groove 2022 on its upper part, and a piston sealing pressure ring 203 is provided around the outer side of the sealing embedding groove 2022. The piston sealing pressure ring 203 is tightly fitted to the inner side of the sealing embedding groove 2022.

[0032] A fixed sealing ring 204 is provided on the upper outer side of the lower piston port 2021. A piston sealing fastener 205 is fixedly connected to the outside of the fixed sealing ring 204. A fixed limiting ring 2051 is provided on the upper inside of the piston sealing fastener 205. The fixed limiting ring 2051 is used to fix and limit the movement between the fixed sealing rings 204. A joint sealing ring 303 is also provided around the lower part of the connector 3. The joint sealing ring 303 is mainly made of high elastic silicone rubber. A filter ring 302 is fixed to the outside of the joint sealing ring 303. Multiple filter holes 3021 are provided on the outer periphery of the filter ring 302 to facilitate the rapid intake of water from the upper part of the connector 3 through the filter holes 3021. The contact gap between the spring extension rod 2011 and the piston through hole 2023 is less than 0.05 mm. The contact gap can be adjusted by adjusting the transverse cross-sectional diameter of the spring extension rod 2011 according to the drainage requirements of the drainer application. The float housing 1 is integrally molded in one piece using an injection molding process.

[0033] Instructions for use: When using this utility model device: a novel floating drainer, refer to the attached instruction manual. Figure 6It can be seen that when the float shell 1 floats upward due to the buoyancy of the water, the float shell 1 stops floating due to the constraint and limitation of the lever fixing seat 101 on the float lever 1011 at the top of the float shell 1. The corresponding valve core 102 and valve core seal 103 move upward, allowing the liquid-gas mixture to enter the inner cavity. The spring extension rod 2011 at the bottom of the piston spring 201 and the piston through hole 2023 have a direct contact gap of less than 0.05 mm. With this setting, and the spring extension rod 2011 being subjected to the combined force of the mixed water and vapor, the main external water comes from the filter through hole 3021 on the filter ring 302. After entering and converging into the piston through hole, the water and vapor can be quickly squeezed out to the outside. It should be noted that the contact gap is set to be less than 0.05 mm because if the gap is too large, the inner cavity 2 and the float shell 1 will be completely connected, and differential pressure drainage will not be possible. The spring extension rod 2011 has a relatively small vertical displacement range, which makes the entire water collection and drainage process stable and reliable.

[0034] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements to the above specific embodiments.
