Abstract
The invention provides a negative pressure testing apparatus for a steel pipe. The negative pressure testing apparatus comprises a workbench; detection devices are arranged on the workbench; and an elevating Y-shaped bracket is arranged between the detection devices. The negative pressure testing apparatus is simple in structure and reasonable in design; when the negative pressure testing apparatus works, the steel pipe is put on the elevating Y-shaped bracket, and the horizontal height of the steel pipe is adjusted through upward and downward movement of the elevating Y-shaped bracket; when the steel pipe and a flange on a cylinder are located on a same horizontal line, the cylinder pushes the flange to clamp the steel pipe, air is sucked through a suction opening on the flange, so negative pressure testing of the interior of the steel pipe is realized. The negative pressure testing apparatus can be operated by only one person, is simple and convenient to operate, saves a great amount of manpower and material resources, has low cost and fast speed, obtains more accurate data, improves work efficiency and better meets demands of manufacturers.
Description
Technical field
The present invention relates to steel pipe technical field of negative pressure, particularly a kind of steel pipe negative-pressure testing device.
Background technology
The development of steel pipe's production technology start from the manufacturing rise of bicycle, 19th century younger oil exploitation, the manufacture of naval vessel, boiler, aircraft during Two World Wars, the manufacture of apparatus of thermo-electric power boiler after World War II, the development of chemical industry and the drilling of petroleum gas and transport etc., all effectively promote the development of Steel Tube Industries on kind, seed output and quality.Steel pipe not only for carrying fluid and powdery solid, exchange heat energy, manufacturing machine part and container, it or a kind of economic steel.The applicable approach of steel pipe is very extensive, so higher to the negative pressure requirements of steel pipe, and existing producer adopts manual testing after steel pipe's production, complex steps, need a large amount of human and material resources, cost is higher, measure the impact that the result obtained is subject to each side simultaneously, measured data are inaccurate, affect its work efficiency, can not meet the demand of producer.
Summary of the invention
Problem to be solved by this invention is to provide a kind of steel pipe negative-pressure testing device, solve existing producer and adopt manual testing after steel pipe's production, complex steps, need a large amount of human and material resources, cost is higher, and measure the impact that the result obtained is subject to each side, measured data are inaccurate simultaneously, affect its work efficiency, can not meet the problem of the demand of producer.
For overcoming the above problems scheme of the present invention:
A kind of steel pipe negative-pressure testing device, comprise worktable, described worktable is provided with pick-up unit, described pick-up unit is two, with the center line of worktable for axis of symmetry is arranged axisymmetricly, Liftable type Y type bracket is provided with between described pick-up unit, described Liftable type Y type bracket is two, with the center line of worktable for axis of symmetry is arranged axisymmetricly, described pick-up unit and Liftable type Y type bracket are on the same line, described pick-up unit comprises bracing frame, described bracing frame is achieved a fixed connection by bolt and worktable, described bracing frame is vertically provided with cylinder, described cylinder comprises cylinder body and piston rod, described piston rod one end is connected with cylinder body, the other end is provided with ring flange, described ring flange is provided with air entry.
The beneficial effect of this programme:
A kind of steel pipe negative-pressure testing device provided by the invention, structure is simple, reasonable in design, when steel pipe negative-pressure testing device works, first steel pipe is placed on Liftable type Y type bracket, the level height of up-down adjustment steel pipe is carried out by Liftable type Y type bracket, when the ring flange on steel pipe and cylinder in the same horizontal line, ring flange clamping steel pipe is promoted by cylinder, the air entry on ring flange is utilized to carry out air-breathing, realize testing the negative pressure of steel duct, only need a people can realize operation, method is simple, simple operation, save a large amount of manpowers, material resources, cost is lower, speed, measured data are more accurate, promote work efficiency, more can meet the demand of producer.
