Description

Technical Field

[0001] The utility model relates to the technical field of steam traps, and particularly relates to an air steam trap. Background Technique

[0002] The air steam trap has the following main functions: firstly, it excludes the air mixed in the pipeline system, prevents the formation of air blockage, ensures the smooth flow of fluid, and improves the operating performance of the system; secondly, it accurately distinguishes steam and condensate, prevents steam leakage, avoids energy waste, reduces operating costs and eliminates potential safety hazards; thirdly, it automatically discharges steam condensate to prevent its accumulation from causing water hammer phenomenon, ensures the stable operation of the system, and prolongs the service life of the equipment.

[0003] The patent publication number "CN220980988U" discloses a "high-temperature and high-pressure steam trap", which includes a high-temperature and high-pressure steam trap body. One side of the high-temperature and high-pressure steam trap body is provided with an outlet. A connecting pipe is threadedly connected inside the outlet. The other end of the connecting pipe is provided with a housing. A disc is arranged at the bottom of the housing. When the condensate and air are discharged through the outlet, the water vapor is sprayed into the interior of the housing through the connecting pipe. Subsequently, the conical bowl weakens the expansion speed of the gas, and the gas is discharged through the air holes and the discharge pipe. At the same time, the condensate flows out through the diversion groove and is then discharged through the discharge pipe, so that the noise emitted by the device can be effectively reduced. The user can pull the female buckle, then take the female buckle out of the male buckle, and then pull the disc to drive the inner housing and the conical bowl to be taken out, so that the interior of the device can be effectively disassembled and cleaned.

[0004] In the device of the above patent, the condensate flows out from the diversion groove and is then discharged through the discharge pipe. If the water vapor discharged from the steam trap carries impurities and it is difficult to effectively filter them, the impurities may accumulate inside the inner housing device. If they accumulate for a long time, problems such as blockage may occur inside, affecting the normal operation of the equipment. Content of the Utility Model

[0038] Furthermore, through the drainage grooves 54 respectively formed between the outer surface of the first conical frame 52 of the first processing mechanism 5 and the inner wall of the processing box 4, condensed water can be effectively introduced into the annular frame 51. Then, the detachable filter block 55 installed on the bottom wall of the annular frame 51 can intercept and filter the condensed water. The condensed water after interception and filtration is discharged through the water outlet holes 56 respectively formed on the bottom wall of the annular frame 51 and penetrating the bottom surface.

By the support columns 9 respectively installed on the bottom surface of the treatment tank 4, the gravity borne by the treatment tank 4 can be effectively supported. At the same time, the reflective strips 10 respectively installed on the outside of the treatment tank 4 can effectively play a warning role.

[0043] Working principle: Through the connecting pipe 2 installed at the outlet end of the steam trap body 1, the hot gas and moisture can be effectively transported to the first treatment mechanism 5. Then, through the drainage grooves 54 respectively opened between the outer side of the surface of the first conical frame 52 and the inner wall of the treatment tank 4, the condensed water can be effectively introduced into the annular frame 51. Then, the detachable filter block 55 installed on the bottom wall of the annular frame 51 can intercept and filter the condensed water. The intercepted and filtered condensed water is discharged through the water outlet holes 56 respectively opened on the bottom wall of the annular frame 51 and penetrating the bottom surface. Then, through this interception and filtration effect, it can prevent impurities from accumulating in the internal shell device in the case of difficult effective filtration. The bottom surface of the annular frame 51 is placed on the top surface of the support block 8, and one side surface of the support block 8 is installed between the inner walls of the treatment tank 4. The box cover 3 clamped to the top end of the treatment tank 4 can effectively play a sealing role to prevent hot gas leakage. In addition, the hollow design of the treatment tank 4 and the box cover 3 can effectively achieve a heat insulation effect. The bottom end of the connecting pipe 2 is fixedly installed on the top surface of the box cover 3 and penetrates the bottom surface. The bottom end of the connecting pipe 2 is located above the first conical frame 52. Through the first conical frame 52, the gas expansion speed can be effectively reduced. Subsequently, the gas is discharged through the first through holes 53 respectively opened on the surface and penetrating the top wall. Through the small conical frame 57 installed on the bottom surface of the annular frame 51, the falling condensed water can be effectively made to fall close to the inner wall surface of the treatment tank 4.

[0044] The second processing mechanism 6 can further effectively reduce the gas expansion speed by being clamped to the second conical frame 62 on the outer side of the top end of the connection frame 61. Subsequently, the gas is discharged through the second through holes 63 respectively opened on the surface and penetrating the top wall. The condensed water sliding on the inner wall of the processing box 4 drips onto the bottom of the box through the water outlets 64 respectively opened between the inner walls and on the outer surface of the connection frame 61. The outer surface of the connection frame 61 is installed between the inner walls of the processing box 4. The condensed water dripping onto the bottom surface of the processing box 4 and the air pass through the discharge port 7 into the valve 11, and then are discharged to the outside for the next step of processing. The discharge port 7 is opened on the bottom wall of the processing box 4 and penetrates the bottom surface. The top end of the valve 11 is installed at the bottom end of the discharge port 7. By the support columns 9 respectively installed on the bottom surface of the processing box 4, the gravity borne by the processing box 4 can be effectively supported. At the same time, the warning function can be effectively exerted by the reflective strips 10 respectively installed on the outside of the processing box 4.
