The purpose of this utility model and to solve its technical problem be realize by the following technical solutions.According to the detachable combining nozzle of one that the utility model proposes, comprise nozzle carrier, combining nozzle, retaining pin, this nozzle carrier is fixed on the baffle plate of orifice plate pressure reducer, and the top of its outer end is provided with the first half slot; This combining nozzle is arranged in the groove of nozzle carrier, and the back side of its outer lug boss is provided with the second half slot, and described second half slot is consistent with this first half slot shape, and opening direction is contrary; This retaining pin snaps in the first half slot of aligning and the circular groove of the second half slot formation.
The purpose of this utility model and solve its technical problem be adopt following technical measures realize further.
Aforesaid detachable combining nozzle, is provided with internal thread in the groove of wherein said nozzle carrier; The outer surface of described combining nozzle is provided with external screw thread, and is meshed with internal thread set by nozzle carrier.
Aforesaid detachable combining nozzle, the external diameter of wherein said combining nozzle outer lug boss is consistent with the external diameter of nozzle carrier.
Aforesaid detachable combining nozzle, wherein said second half slot is provided with more than 10.
The utility model compared with prior art has obvious advantage and beneficial effect.By technique scheme, a kind of detachable combining nozzle of the utility model can reach suitable technological progress and practicality, and has the extensive value in industry, and it at least has following advantages:
1, replacement operation is simple, quick-replaceable under the mode not using cutting and welding, and by stopping work, the time changed at least shortens more than 2/3rds;
2, can arbitrarily quantity change, tool convenience.If damage 30 during maintenance, 30 that this damages only can be changed;
3, owing to not needing the mode adopting cutting machine welding, the baffle plate of orifice plate pressure reducer can not be damaged, thus the life cycle of orifice plate pressure reducer is extended more than one times;
4, due in the utility model combining nozzle and nozzle carrier be not one, only need change old nozzle during replacing, and not need to change nozzle carrier or orifice plate pressure reducer baffle plate, reduce replacement cost.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of description, and can become apparent for allowing above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Detailed description of the invention
For further setting forth the utility model for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to its detailed description of the invention of detachable combining nozzle, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
Refer to Fig. 1 and Fig. 2, a kind of detachable combining nozzle of the utility model, comprise nozzle carrier 2, combining nozzle 3, retaining pin 4, this nozzle carrier 2 affixed (can adopt welding) is on the baffle plate 1 of orifice plate pressure reducer, its outer end is provided with the first half slot 21, and is placed on the top of nozzle carrier 2 outer end.This combining nozzle 3 is arranged in the groove of nozzle carrier 2, and the external diameter of its outer lug boss is consistent with the external diameter of nozzle carrier 2.Please refer to Fig. 3, the back side of this outer lug boss is provided with the second half slot 31, and this second half slot 31 is consistent with the shape of the first half slot 21 of nozzle carrier 2 outer end, and opening direction is contrary.This retaining pin 4 snaps in the circular groove that the first half slot 21 of aligning and the second half slot 31 formed, and prevents combining nozzle 3 from exiting from the thread groove of nozzle carrier 2 easily.
Concrete, be provided with internal thread in the groove of said nozzle seat 2, the outer surface of above-mentioned combining nozzle 3 is provided with external screw thread, and is meshed with internal thread set by nozzle carrier 2, is convenient to operating personnel like a cork by the groove of combining nozzle 3 precession nozzle carrier 2.
Concrete, the second above-mentioned half slot 31 is provided with more than 10.
Concrete, above-mentioned retaining pin 4 is cylindrical, consistent with the diameter of the first half slot 21 set by nozzle carrier 2, the second half slot 31 set by combining nozzle 3.Time in the groove of combining nozzle 3 precession nozzle carrier 2, only need aim at the first half slot 21, second half slot 31, then retaining pin 4 be snapped in the two circular groove formed.
The using method of a kind of removable nozzle of brief description the utility model.
When using first, nozzle carrier 2 is weldingly fixed on orifice plate pressure reducer baffle plate 1, again combining nozzle 3 is spun in the helicla flute of nozzle carrier 2, finally retaining pin 4 is snapped in uppermost two half slots that combining nozzle 3 aims at nozzle carrier 2, the installation of combining nozzle 3 can be completed.Refer to Fig. 3 and Fig. 4, when changing old combining nozzle 3, retaining pin 4 is extracted, screw out old combining nozzle 3, and the helicla flute of nozzle carrier 2 is simply cleaned.Then the external screw thread of new combining nozzle 3 is filled high-temperature adhesives, match with the internal thread of nozzle carrier 2, it is screwed in easily in nozzle carrier 2, while screwing, make second half slot 31 at the combining nozzle 3 outer lug boss back side aim at uppermost first half slot 21 of nozzle carrier 2.Last again retaining pin 4 to be inserted in the circular groove that the first half slot 21 and the second half slot 31 formed, guarantee that combining nozzle 3 is fastened in the helicla flute of nozzle carrier 2, can not exit.
Adopt a kind of detachable combining nozzle of the utility model, replacement operation is convenient, and quality reaches a standard.Owing to not needing the mode adopting cutting and welding, can not defective nozzle seat, new combining nozzle and orifice plate pressure reducer baffle plate, thus the life cycle of orifice plate pressure reducer is extended more than one times, thus making user reduce by the expense of about 2/3rds, shut-down replacing construction at least shortens about 2/3rds simultaneously.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
