Abstract
The utility model discloses a purging nozzle and belongs to industrial purging nozzles. The purging nozzle is mainly used for dirt purging and cleaning of chemical pipelines, instrument pipelines and industrial heat exchangers. The purging nozzle is characterized in that a nozzle head (2), a nozzle front section (5), a nozzle middle section (8) and a nozzle rear section (10) have an integrated concentric shaft structure; a through hole front section (4) and a nozzle through hole (6) are formed in the axis of the purging nozzle; the nozzle middle section (8) with small outer diameter is formed between the nozzle front section (5) and the nozzle rear section (10); a groove (7) is formed; the nozzle head (2) is provided with an external thread (3); a foremost injection hole (1) in the through hole front section (4) has the smallest inner diameter; the inner diameter on the rear part is the same as that of the nozzle through hole (6); and an internal thread (9) is formed at the rear part of the nozzle through hole (6). The purging nozzle has the characteristics of simple structure, convenience in connection, centralized injection hole jet flow and good purging effect.
Description
Technical field
The utility model belongs to a kind of industrial purge nozzle.
Background technology
At present, on industrial production, purge various pipelines, instrumentation and generally adopt the high-pressure fluid method, such as: high steam, nitrogen, high-pressure blast, the purger that at this moment adopts is relative complex also.And to the purging of equipment, generally at one section hard tube of flexible pipe front end socket, by it, jet-impingement is purged on object to quilt, these methods look simple and practical, but really have certain hidden danger, sometimes because of the getting loose of hard tube and flexible pipe, hard tube with Fluid injection to being purged on object, cause the equipment accidental damage, the accident of the person sometimes also can occur injuring.Entangling its reason, is mainly the hard tube that uses as purge nozzle, no matter is outer surface, or inner surface, does not all have to be fit to can conveniently connect, can connect firm structure again with other flexible pipe.
The utility model content
The utility model provides a kind of purge nozzle, solves the problems of the technologies described above, and realizes using safety, connection and convenient disassembly.
The technical scheme that solves above technical problem is: nozzle head (2), nozzle leading portion (5), nozzle stage casing (8) and nozzle back segment (10) are the concentric shafts structure of one, are provided with through hole leading portion (4) and through nozzle hole (6) at the place, axle center of purge nozzle.Be the thinner nozzle stage casing (8) of external diameter between nozzle leading portion (5) and nozzle back segment (10), and form groove (7), nozzle head (2) is provided with external screw thread (3).The spray orifice foremost (1) of through hole leading portion (4) is located interior through minimum, and rearmost internal diameter is identical with the internal diameter of through nozzle hole (6).Be provided with internal thread (9) at the rear portion of through nozzle hole (6).
Through above technological improvement, its beneficial effect is obvious: purge nozzle is same connection, convenient disassembly with flexible pipe or hard tube, connects firm intensity large, can not come off easily, can effectively avoid various relevant accidents to occur.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model, and Fig. 2 is cutaway view of the present utility model.
The specific embodiment
In Fig. 1, Fig. 2: nozzle head (2), nozzle leading portion (5), nozzle stage casing (8) and nozzle back segment (10) are the concentric shafts structure of one, and its integral body is cylindrical.
Place, axle center in purge nozzle is provided with through hole leading portion (4) and through nozzle hole (6), both mutually connects.Be the thinner nozzle stage casing (8) of external diameter between nozzle leading portion (5) and nozzle back segment (10), and form groove (7), this spline structure of groove (7) is conducive to flexible pipe and is fixed on purge nozzle by clip.Nozzle head (2) is provided with external screw thread (3), can be with being connected by purger.The spray orifice foremost (1) of through hole leading portion (4) is located the internal diameter minimum, rearmost internal diameter is identical with the internal diameter of through nozzle hole (6), the pressurization that is conducive to like this air-flow makes in the air flow collection of spray orifice (1) ejection, and the ability of removing dirt is high-strength.Be provided with internal thread (9) at the rear portion of through nozzle hole (6), by internal thread (9), purge nozzle is being connected of convenient and flexible pipe not only, can also connect with hard tube, and it has stronger practicality like this.
Claims (3)
