Technical field
The utility model relates to the cleaning technique of seamless steel pipe, more particularly, relates to a kind of seamless steel pipe internal wall cleaning spray gun, and this cleaning spray gun can help preventing the leakage of cleaning fluid.
Background technology
Seamless steel pipe is behind cold deformation, can there be impurity such as certain lubricant grease and metallic particles in its inner wall surface, particularly the small-bore seamless steel pipe (is internal diameter≤8mm, wall thickness≤1mm), because it is mainly used in special dimensions such as space flight, nuclear power and medicine, the cleannes of its inner wall surface require high, therefore must clean, eliminate.At present, the cleaning way of seamless steel pipe internal wall is: adopt earlier liquid medium that steel pipe is carried out soaking and washing, by artificial proficiency seamless steel pipe one end of holding with a firm grip, another hand grips cleaning spray gun, aims at pore inject high pressure cleaning fluid, cleans the steel pipe inner wall surface again.But, because caliber is less, the spray gun shower nozzle with treat that pore does not match, in actual mechanical process, have following shortcoming:
1) can't keep aiming at all the time between spray gun shower nozzle and the pore, fixing, during flushing, high-pressure cleaning liquid easily leaks, sprays even splashes, and has influenced cleaning performance and cleaning efficiency greatly;
2) because steel pipe is thinner, smooth surface, the steel pipe of manually will under impacting with high pressure, holding with a firm grip all the time, comparatively difficulty, and long working, labour intensity is bigger;
3) used cleaning fluid has certain corrosivity, if spray, splash on one's body the operating personnel, easily damages, and therefore has potential safety hazard.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of seamless steel pipe internal wall cleaning spray gun, and this cleaning spray gun can prevent that in use cleaning fluid from leaking, and improves cleaning performance.
For achieving the above object, the utility model adopts following technical scheme:
This seamless steel pipe internal wall cleaning spray gun comprises the rifle body and is located at the shower nozzle of rifle body one end, and this cleaning spray gun comprises that also one is used to be communicated with and the connector of stationary nozzle and seamless steel pipe, and this connector is located on the shower nozzle, and an end is connected with shower nozzle and communicates.
Described connector comprises tube connector, inner sleeve and the outer tube that is connected successively, and tube connector one end is placed on the shower nozzle, and connects by threaded engagement; Inner sleeve one end stretches in the tube connector fixing, and other end inside is provided with seal member; Outer tube one end is placed on the inner sleeve, and connects by threaded engagement.
Described seal member comprises several " O " RunddichtringO and shading rings, and " O " RunddichtringO and shading ring are provided with separately.
The internal diameter of described " O " RunddichtringO and shading ring and the external diameter of described seamless steel pipe are suitable.
Also be with sealing ring on the inserting end of described inner sleeve.
In technique scheme, seamless steel pipe internal wall cleaning spray gun of the present utility model comprises the rifle body and is located at the shower nozzle of rifle body one end, cleaning spray gun comprises that also one is used to be communicated with and the connector of stationary nozzle and seamless steel pipe, and connector is located on the shower nozzle, and an end is connected with shower nozzle and communicates.During use, seamless steel pipe is inserted in the seal member of inner sleeve, and tighten outer tube, make " O " RunddichtringO to seamless steel pipe axial location and fit sealing radially, thereby prevent that effectively cleaning fluid from leaking, spraying or splash, improved cleaning performance and cleaning efficiency, and need not hand steel pipe.Not only reduce labour intensity, and stopped potential safety hazard.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 1, seamless steel pipe internal wall cleaning spray gun 10 of the present utility model is basic identical with traditional spray gun, equally also comprise rifle body 11 and the shower nozzle 12 of being located at rifle body 11 1 ends, also be provided with switch 13 on the rifle body 11, and the other end of rifle body 11 bottom also is provided with oral siphon joint 14.Be that with the difference of prior art comprise also that at this cleaning spray gun 10 one is used to be communicated with and the connector 20 of stationary nozzle 12 and seamless steel pipe 1, this connector 20 is located on the shower nozzle 12, and left end is connected with shower nozzle 12 and communicates.Please in conjunction with Fig. 2～shown in Figure 5, this connector 20 comprises tube connector 21, inner sleeve 22 and the outer tube 23 that is connected successively, and tube connector 21 left end inside are provided with internal thread, and are sheathed on the shower nozzle 12, and be connected and fixed by threaded engagement, the right-hand member inside of tube connector 21 is step-like.Inner sleeve 22 left end inside are the cone shape suitable with shower nozzle 12, and this end outer wall also is step-like; The right-hand member inside of inner sleeve 22 is provided with seal member 24, and the outer wall of this end is provided with external screw thread, inner sleeve 22 penetrates from tube connector 21 left ends by right-hand member, and passes from tube connector 21 right-hand members, and the left end outer wall step of inner sleeve 22 matches fixing with tube connector 21 right-hand member interior step; Also be with a sealing ring 25 in the left side of inner sleeve 22 steps, be used for the sealing of two step cooperation places.Outer tube 23 left ends are provided with internal thread, and are placed on the right-hand member of inner sleeve 22, and are connected and fixed by threaded engagement; The right-hand member inside of outer tube 23 is step-like.Above-mentioned seal member 24 comprises several " O " RunddichtringOs 241 and shading ring 242 (quantity of " O " RunddichtringO 241 shown in Fig. 1, Fig. 2 and shading ring 242 respectively is four), " O " RunddichtringO 241 is arranged in the inner sleeve 22 separately with shading ring 242, and the internal diameter of " O " RunddichtringO 241 and shading ring 242 is suitable with the external diameter of the seamless steel pipe 1 that needs to clean.The material of " O " RunddichtringO 241 is an acrylonitrile-butadiene rubber, and the material of shading ring 242 and sealing ring 25 is a nylon.
