Description
Technical field
The invention belongs to hydrostatic testing machine tool technical field, relate in particular to a kind of pneumatic steel pipe hydrostatic tester.
Background technology
Hydrostatic testing machine is exactly by water pump water filling in the steel pipe, makes that in steel pipe, hydraulic pressure reaches test pressure, and whether inspecting containers leaks.And the structure that is used for detecting the hydrostatic testing machine of use in present Steel Pipe Enterprise generally comprises a location-plate, then is provided with threaded rod on location-plate, and an end of threaded rod is connected with seal.When in use the monoblock location-plate is fixed in a tank, fixes location-plate by the clamping plate of tank both sides, then the turn threaded rod carries out the sealing to pipe.This type of be more easy hydrostatic testing machine, can regulate according to the length of pipe the position of location-plate.Its defective is: the one, and, it is unstable in sealing that pipe need to seal an end, easily makes sealing effectiveness bad, thereby cause the failure of an experiment; The 2nd,, will move location-plate when needs are regulated location-plate, and location-plate is all heavier, thus very inconvenient when regulating, cause and use inconvenience.
Summary of the invention
The object of the invention is to solve above-described technical matters, a kind of pneumatic steel pipe hydrostatic tester is provided, its technical scheme is as follows:
A kind of pneumatic steel pipe hydrostatic tester comprises base plate, and described base plate is provided with support, described support is provided with cylinder, described cylinder is connected with upper clamp formwork, and the below place that is positioned at upper clamp formwork on described base plate is provided with lower clamp formwork, the clamping that can match of described upper clamp formwork and lower clamp formwork; The bottom of described base plate is fixed with axle, and the two ends of described axle are provided with arbor wheel; The sidepiece of described base plate is provided with some L shaped limiting plates, and described L shaped limiting plate is provided with side wheel; Described base plate is provided with sealing socket, and described sealing socket is provided with threaded rod, and an end of described threaded rod is provided with seal pad, arranges with the seal pad coaxial line after described upper clamp formwork and lower clamp formwork closure.Optimal way is that described upper clamp formwork is provided with lower clamp formwork the guard collar that clamping is mutually mated.
Pneumatic steel pipe hydrostatic tester provided by the invention when in use, is first adjusted the position of whole base plate according to the length of pipe.The arbor wheel of general both sides of the present invention is arranged on tank, by L shaped limiting plate can so that whole base plate can be limited in can only the enterprising line slip of tank.Arbor wheel and side wheel are all to slide when sliding.So can adjust very easily the position of base plate according to the actual needs of pipe.After adjusting the position of base plate, pipe is placed on lower clamp formwork, then by cylinder, makes upper clamp formwork press down, until upper clamp formwork and lower clamp formwork coordinate tube grip.At this moment, can the hand rotation threaded rod, make seal pad to the nipped end motion of pipe, until seal pad is pipe sealing.Just can carry out the hydraulic testing this moment.
Arrange with the seal pad coaxial line after upper clamp formwork of the present invention and lower clamp formwork closure.When upper clamp formwork and lower clamp formwork clamped closed and seal pad be the coaxial line setting, like this can be so that pipe be when being jammed, seal pad can be the coaxial line setting with pipe, makes seal pad the better tightness of the sealed tube period of the day from 11 p.m. to 1 a.m.Make seal pad stressed situation when the hydraulic testing more even, can play the effect that extends its service time.
Be the U-shaped groove that is provided with mutual correspondence on upper clamp formwork of the present invention and lower clamp formwork, place pipe in the U-shaped groove and use, can be more steady so that pipe is placed.Described upper clamp formwork is provided with lower clamp formwork the guard collar that clamping is mutually mated.And guard collar is all generally plastic material, can prevent that the outside surface of pipe from wearing and tearing due to stressed.
The present invention has adopted the pneumatic clamping mode, has adopted the U-shaped sealing means, and making can maximum pressure-bearing: 20MPa.
The present invention can test the needs of pipe and position very convenient, laborsaving, that adjust efficiently whole hydrostatic testing machine makes the sealing of whole hydrostatic testing machine more outstanding according to reality.
