Abstract
The utility model discloses a nozzle for rinsing inner bores of a steel tube. The nozzle comprises a threaded connection part and a spraying part, wherein a high-pressure spraying cavity is arranged in the spraying part, the periphery of the spraying part is in a cone frustum shape, and an auxiliary cylinder extends in a protruding mode from the head part of the spraying part; the diameter of the auxiliary cylinder is less than the diameter of the end part of the spraying part; and the periphery of the auxiliary cylinder is surrounded by a spraying port of the high-pressure spraying cavity. The nozzle has a simple structure and can be used for rinsing steel tubes of different diameters, therefore, the nozzle is not needed to be frequently replaced during rinsing, and the efficiency and quality of rinsing are improved.
Description
Technical field
The utility model relates to a kind of nozzle, is meant that especially the flushing of a kind of steel tube inner hole uses nozzle.
Background technology
The cleaning of seamless steel pipe inner bore at present generally is to utilize high-pressure oil passage to connect nozzle endoporus is washed; Present then nozzle can only be suitable for a certain size steel pipe; The perhaps steel pipe of the less all size of application diameter difference in size; The two kind steel pipes bigger for diameter difference then can't use, even perhaps use, the effect of flushing does not reach predetermined requirement yet.
The utility model content
The utility model technical problem to be solved is: provide a kind of steel tube inner hole flushing to use nozzle; This nozzle arrangements is simple; Can be suitable for the steel pipe flushing of different-diameter size, thereby in flushing process, need not too much replacing nozzle, improve the efficient and the quality of flushing.
For solving the problems of the technologies described above; The technical scheme of the utility model is: nozzle is used in a kind of steel tube inner hole flushing; Comprise threaded joints and ejection section, be provided with the high-pressure injection chamber in the said ejection section, the periphery of said ejection section is that truncated cone and head have protruded out auxiliary cylinder; The diameter of said auxiliary cylinder is less than the diameter of the end of ejection section, and the injection tip in said high-pressure injection chamber is around being arranged in external week of said reinforcing post.
As a kind of preferred scheme, extension is shunk gradually along injection direction in said high-pressure injection chamber.
As a kind of preferred scheme, said high-pressure injection chamber comprises four conical injection channels, and said injection channel is around the periphery of even cloth at auxiliary cylinder.
After having adopted technique scheme, the effect of the utility model is: because the periphery of said ejection section is that truncated cone and head have protruded out auxiliary cylinder, the diameter of said auxiliary cylinder is less than the diameter of the end of ejection section; The injection tip in said high-pressure injection chamber is around being arranged in external week of said reinforcing post, therefore, and can be for the steel pipe that diameter is bigger with the periphery of steel pipe socket in ejection section; Nozzle and steel pipe are combined closely; Thereby developing result is good, and for the less steel pipe of diameter, can be enclosed within on the auxiliary cylinder steel tube end part and the end of steel tube end part and ejection section closely cooperates; This is; The injection tip in high-pressure injection chamber is in the interior flushing that realizes steel tube inner hole of endoporus of steel pipe equally, and like this, this nozzle can satisfy the rinsing requirement of the bigger steel pipe of diameter difference; Thereby in flushing process, need not too much replacing nozzle, improve the efficient and the quality of flushing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structure cutaway view of the utility model embodiment;
Fig. 2 is the left view of Fig. 1;
In the accompanying drawing: 1. threaded joints; 2. ejection section; 3. spray chamber; 31. injection channel; 4. auxiliary cylinder; 5. supporting clapboard.
The specific embodiment
Through specific embodiment the utility model is done further to describe in detail below.
Nozzle is used in a kind of steel tube inner hole flushing; As depicted in figs. 1 and 2; Comprise threaded joints 1 and ejection section 2, be provided with high-pressure injection chamber 3 in the said ejection section 2, the periphery of said ejection section 2 is that truncated cone and head have protruded out auxiliary cylinder 4; The diameter of said auxiliary cylinder 4 is less than the diameter of the end of ejection section 2, and the injection tip in said high-pressure injection chamber 3 is around being arranged in said auxiliary cylinder 4 peripheries.Extension is shunk gradually along injection direction in preferred said high-pressure injection chamber 3, and said high-pressure injection chamber 3 comprises four conical injection channels 31, and said injection channel 31 is around the periphery of even cloth at auxiliary cylinder 4.
In the present embodiment; Be provided with supporting clapboard 5 in the said spray chamber 3; The afterbody of said auxiliary cylinder 4 and supporting clapboard 5 are fixing, and the head of auxiliary cylinder 4 stretches out from the spray end of ejection section 2, and described four injection channels 31 extend to the spray end of ejection section 2 from supporting clapboard 5.Certainly, also can be that auxiliary cylinder 4 directly stretches out from spray end.
The operation principle of the utility model is: at first nozzle is connected in the high-pressure oil passage of washer; End with steel pipe is enclosed within on the nozzle then, and the steel pipe bigger like diameter can directly be sleeved on the conical surface of ejection section 2 peripheries, and the design of the conical surface can be suitable for the steel pipe that can be enclosed within all size on the conical surface; Simultaneously; When the diameter of bore of steel pipe hour can't be enclosed within on the conical surface of nozzle, with steel pipe socket on auxiliary cylinder 4 and the end be close to the spray end of ejection section 2, like this; The injection tip of spray chamber 3 is in the endoporus of steel pipe, the same purpose that realizes the flushing endoporus.
Claims (3)
1. nozzle is used in the steel tube inner hole flushing; Comprise threaded joints and ejection section; Be provided with the high-pressure injection chamber in the said ejection section; It is characterized in that: the periphery of said ejection section is that truncated cone and head have protruded out auxiliary cylinder, and the diameter of said auxiliary cylinder is less than the diameter of the end of ejection section, and the injection tip in said high-pressure injection chamber is around being arranged in external week of said reinforcing post.
