Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a rotatable and bendable shower guide quick-connect device. Background Art

[0002] In the chemical production process, there are many gaseous substances transported in pipelines. When the temperature and pressure drop, they will condense into liquid and accumulate in the low position of the pipeline. If the condensation is not discharged in time, it is easy to induce water hammer and endanger the safety of the device. The traditional measure is to weld a drainage pipe at the low position of the pipeline and control the opening and closing of the drainage pipe by a valve. Although the condensed liquid can be discharged quickly, it is generally installed at a low place and is not convenient to connect with other pipelines. The liquid flowing out of the drainage pipe is mostly discharged directly, which affects the collection of waste liquid and causes pollution.

[0003] Therefore, a technical solution is currently needed to solve the technical problem that during pipeline condensation drainage operations, the shower pipe is located at a low position in the pipeline, is inconvenient to connect with other pipelines, and cannot discharge the condensed liquid to a safe location. Utility Model Content

[0004] The utility model aims to overcome the technical problem that during pipeline condensation discharge operation, the shower guide pipe is at a low position in the pipeline, is inconvenient to connect with other pipelines, and cannot discharge condensed liquid to a safe position, and provides a rotatable and bendable shower guide quick-connect device.

[0005] The utility model provides a rotatable and bendable shower guide quick-connect device, comprising a bellows, a drainage pipe and a quick connector, wherein one end of the bellows is connected with a sleeve for connecting with the shower guide pipe, and the other end is connected with the drainage pipe through the quick connector.

[0006] The utility model discloses a rotatable and bendable shower guide quick-connect device. When in use, a sleeve is connected to the shower guide pipe, and the drainage pipe is connected to the bellows through a quick connector. Due to the presence of the bellows, the sleeve can be rotated to facilitate the connection of the sleeve at one end of the bellows to the shower guide pipe. Due to the presence of the bellows, the quick connector can be bent upwards to facilitate the connection of the quick connector to the drainage pipe. Finally, the gas and liquid are guided to a safe position for discharge through the drainage pipe to avoid pollution.

[0007] Preferably, the bellows is a stainless steel structural component.

[0008] The stainless steel bellows are corrosion-resistant and can maintain their strength under high temperature and high pressure conditions, ensuring the smooth discharge of condensed liquid and avoiding leakage of harmful gases or liquids.

[0009] Preferably, a first thread section is provided on the inner wall of the sleeve, and the sleeve is threadedly connected to the shower pipe through the first thread section.

[0010] The sleeve and the shower pipe are detachably connected, and the threaded connection provides a high connection strength between the sleeve and the shower pipe, thereby preventing the sleeve and the bellows connected to the sleeve from being washed away by gas and liquid during the condensate drainage process, thereby ensuring the safety of the condensate drainage operation.

[0011] Preferably, the quick connector includes a main body and a sub-body, the main body is connected to the drainage tube, and the sub-body is connected to the corrugated tube.

[0012] The drainage tube and the bellows are detachably connected, which is easy to operate and has strong sealing performance.

[0013] Preferably, the drainage tube is a structural member made of a flexible material.

[0014] It is convenient to move the orientation and position of the drainage tube during the drainage process so as to better discharge the condensed liquid to a safe area.

[0015] Preferably, one end of the drainage tube away from the quick connector is connected to a ball valve.

[0016] Although valves are installed on the drainage pipe, there is a certain distance between the drainage pipe and the discharge location. By connecting a ball valve at the end of the drainage pipe, the gas and liquid on and off of the condensate discharge process can be controlled in real time to prevent the residual gas and liquid in the drainage pipe from being accidentally discharged to other areas.

[0017] Preferably, the bellows is detachably connected to the sleeve.

[0018] The bellows and the sleeve are detachably connected, so that the sleeve can be replaced on the bellows. When the diameter of the shower pipe changes, sleeves with different inner diameters can be replaced on the bellows to match the change in the diameter of the shower pipe, thereby increasing the application range of the quick-connect device.

[0019] Preferably, one end of the bellows connected to the sleeve is provided with a threaded head, the inner wall of the sleeve is provided with a second threaded section, and the sleeve is connected to the threaded head via the second threaded section.

[0020] A detachable connection between the sleeve and the bellows is realized, two step surfaces are arranged on the inner wall of the sleeve, the first thread section and the second thread section are respectively located on the two step surfaces, the diameter of the second thread section is always matched with the diameter of the thread head, and the first thread section changes with the specification of the sleeve to match the shower pipes of different diameters.

[0021] Preferably, an elastic sealing ring is sleeved on the threaded head, an annular baffle is provided on one end of the threaded head connected to the bellows, and the sleeve is used to press the elastic sealing ring tightly onto the annular baffle.

[0022] An elastic sealing ring is added at the connection between the sleeve and the threaded head to improve the sealing performance between the sleeve and the threaded head and reduce the risk of leakage of harmful gas and liquid.

[0023] Preferably, an annular groove is provided on the annular baffle, and the elastic sealing ring is nested in the annular groove.

[0024] The annular groove has a limiting effect on the elastic sealing ring located therein, thereby preventing the sleeve from being displaced during the process of squeezing the elastic sealing ring, further improving the sealing between the sleeve and the threaded head, and ensuring the safety of the condensate discharge operation.

[0026] 1.
