Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipeline air tightness detection, in particular to air tightness detection equipment for stainless steel pipes. Background Art
[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils. Compared with plastic pipes, stainless steel pipes have superior performance in all aspects, but the pipe wall may be too thin or cracked during the production process. When the wall of stainless steel pipe fittings is too thin or cracks appear, it will cause water leakage during use. Therefore, it is necessary to perform air tightness test on stainless steel pipe fittings. When performing air tightness test on stainless steel pipe fittings, the pressure test is generally used, that is, one end of the stainless steel pipe fitting is sealed, and then the other end is used to inflate or pass water. At this time, observe whether water or gas leaks to determine whether there is a leak. However, the existing stainless steel pipe detection device can only clamp and detect a single stainless steel pipe during detection, and cannot cope with steel pipes of different lengths. The steel pipe cannot be rotated during detection, and it is difficult to accurately check and observe the air leakage of the pipeline; therefore, the present application designs an air tightness detection device for stainless steel pipes to solve the above problems.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Example: See Figure 1-5 The air tightness detection equipment for stainless steel pipes in the utility model comprises a box body 1, a drain pipe 2 is connected to the lower part of one side of the front end surface of the box body 1, a support plate 11 is vertically slidably arranged in the middle part of the box body 1, a plurality of mounting holes are opened on one side of the support plate 11, a clamping tube 3 is arranged inside the mounting holes, and an L-shaped air pump hose 8 is connected to the tail end of the clamping tube 3; an adjusting component for moving the support plate 11 is arranged on the other side of the support plate 11, and through the design of the air pump hose 8, the support plate 11 can be better moved to prevent the pipeline connected to the air pump from loosening due to the repeated movement of the support plate 11.
[0020] In the utility model, the adjustment component includes a threaded tube 5 transversely fixed to the middle part of the other side surface of the support plate 11 and a threaded rod 9 transversely rotatably arranged on the inner wall of one side of the box body 1, the inner end of the threaded rod 9 is connected to the inside of the threaded tube 5, the outer end of the threaded rod 9 movably passes through the outside of the box body 1 and is fixedly connected with a clamping knob 7. Through the design of the guide sleeve 4, the threaded rod 9 and the clamping knob 7, the tightness of the steel pipe clamped by the clamping tube 3 can be better adjusted. The front and rear ends of the other side surface of the support plate 11 are transversely fixed with the guide sleeve 4, and the guide sleeve 4 is movably inserted with a guide column 10. The outer end of the guide column 10 is fixed to the inner wall of the box body 1. Through the design of the guide column 10 and the guide sleeve 4, the support plate 11 can be better slid and supported, to prevent the support plate 11 from being subjected to unbalanced force and the loose clamping of the steel pipe by the guide clamping tube 3, which affects the air tightness detection.
[0021] In the utility model, a butterfly valve 6 is installed on the drain pipe 2. Through the design of the drain pipe 2 and the butterfly valve 6, the water in the box 1 can be discharged more conveniently. A sealing rubber ring 12 is provided inside the pipe mouth of the clamping tube 3. Through the design of the sealing rubber ring 12 at the pipe mouth of the clamping tube 3, the steel pipe port can be better sealed to prevent it from affecting the air tightness inspection. The tail end of the clamping tube 3 is rotatably connected to the inside of the mounting hole through a bearing. Through the design of the rotatable clamping tube 3, the steel pipe can be better rotated and observed.
[0022] Working principle: When using the utility model, first connect the air pump to the air pump hose 8, then observe the length of the steel pipe and initially adjust the clamping knob 7, adjust the distance of the clamping tube 3 to be greater than the length of the steel pipe, and then align one end of the steel pipe with the clamping tube 3, and then rotate the clamping knob 7 again to clamp the steel pipe. The sealing rubber ring 12 at the mouth of the clamping tube 3 can better clamp the steel pipe and cooperate with the steel pipe port to avoid processing defects at the port affecting the air tightness inspection. Finally, turn on the air pump to give a certain pressure to check the air tightness of the steel pipe, and then rotate the clamping knob 7 to remove the steel pipe.
