Abstract
The utility model relates to the field of air pipe network, in particular to a drainage structure of the air pipe network. The drainage structure of the air pipe network comprises a drainage valve. The drainage structure of the air pipe network is characterized in that the drainage valve is vertically arranged above an air conduit, an inlet of the drainage valve is connected with the air conduit through a water absorption tube, the length L1 of the water absorption tube on the outer side of the air conduit is 150-200mm, the end portion of the water absorption tube extends to the air conduit, and an opening of the end portion of the water absorption tube faces the direction of airflow. The distance L2 between a lowest end of the water absorption tube and the bottom of the air conduit is 10-15mm. A right-angle water discharging tube is arranged on an outlet of the drainage valve. Compared with the prior art, the drainage structure of the air pipe network has the advantages that the drainage valve installed upward can discharge water at any time in winter, solves the problem that a valve is disintegrated in winter, reduces operating time of changing the drainage valve caused by that the drainage valve is disintegrated or blocked, and ensures continuous supply of ironmaking, steelmaking, continuous casting and steel rolling for users.
Description
Technical field
The utility model relates to air pipe network field, relates in particular to the online discharge structure of a kind of air duct.
Background technique
All contain the part water vapor in the Normal squeezing air, after entering the air pipe network, moisture can be separated out, so the duct bottom of air pipe network all arranges drain valve usually, drain valve is installed in the pipeline minimum point, in the winter time in, the moisture of separating out often causes the drain valve bursting by freezing, change drain valve and must stop the supple of gas or steam more than 5 hours, affect user's normal production; The phenomenon that the drain valve of installing is downwards in addition also often stopped up by iron scale in the pipeline, rate of fault is higher.
Summary of the invention
The purpose of this utility model is the discharge structure that provides a kind of air duct online to overcome the deficiencies in the prior art, avoids drain valve bursting by freezing in winter phenomenon, reduces the rate of fault of drain valve.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The discharge structure that a kind of air duct is online, comprise drain valve, described drain valve is vertical at the air conduit top, link to each other by suction sleeve between drain valve entrance and the air conduit, the suction sleeve length L 1 in the air conduit outside is 150-200mm, the suction sleeve end extends air conduit inside, and suction sleeve is open-ended meets to airflow direction.
The least significant end of described suction sleeve is 10-15mm apart from air conduit bottom L2.
The outlet of described drain valve is provided with the right angle outlet pipe.
Compared with prior art, the beneficial effects of the utility model are: the drain valve of upwards installing, in at any time draining in winter, solved the difficult problem of valves in winter bursting by freezing, reduced the replacing number of times of operation that causes because of drain valve bursting by freezing or obstruction, guaranteed that ironmaking, steel-making, continuous casting and each user's of steel rolling is without interruption.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Wherein: 1-drain valve 2-air conduit 3-suction sleeve 4-right angle outlet pipe
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, it is the online discharge structure example structure schematic representation of a kind of air duct of the utility model, comprise drain valve 1 and air conduit 2, drain valve 1 is vertical at air conduit 2 tops, link to each other by suction sleeve 3 between drain valve 1 entrance and the air conduit 2, suction sleeve 3 length L 1 in air conduit 2 outsides are 150-200mm, and suction sleeve 3 ends extend air conduit 2 inside, in order to make suction sleeve 3 open-ended meeting to airflow direction, suction sleeve 3 end cut become 45 degree.
The least significant end of suction sleeve 3 is 10-15mm apart from air conduit 2 bottom L2, can prevent that the iron scale in the air conduit from entering in the drain valve, causes valve blockage.The outlet of drain valve 1 is provided with right angle outlet pipe 4.
When the needs draining, open drain valve 1, the moisture in the air conduit 2 is sucked out by the siphonage of suction sleeve 3, discharges from right angle outlet pipe 4, and can not be deposited in the drain valve 1, thereby solved the difficult problem of valves in winter bursting by freezing.
Claims (3)
1. discharge structure that air duct is online, comprise drain valve, it is characterized in that, described drain valve is vertical at the air conduit top, link to each other by suction sleeve between drain valve entrance and the air conduit, the suction sleeve length L 1 in the air conduit outside is 150-200mm, and the suction sleeve end extends air conduit inside, and suction sleeve is open-ended meets to airflow direction.
2. the online discharge structure of a kind of air duct according to claim 1 is characterized in that, the least significant end of described suction sleeve is 10-15mm apart from air conduit bottom L2.
