Description
Technical field
The utility model relates to steel-plastic composite pipe pressure test technology field, is specifically a kind of pressure testing device checking tubing.
Background technology
In the production process of steel-plastic composite pipe, must test the short-term hydrostatic strength of tubing and burst strength, detect physical and mechanical properties and the limiting pressure of tubing, to adjust the steel skeleton construction in steel-plastic composite pipe timely, produced product is made to meet standard-required.
At present withstand voltage test pressure testing device used is carried out to steel-plastic composite pipe, substantially be all that the fixing Internal baffle in tubing settles sealing ring, then the outer press cover of employing activity is compressed sealing ring by tools for bolts ' pretension, makes sealed ring deformation to reach the object of tubing pressure testing sealing.Adopt this pressure testing device due in pressure testing process, along with the continuous increase of test pressure, the distortion of steel-plastic composite pipe also can increase thereupon, when tubing deformed more than the decrement of sealing ring time, test failure is made with regard to there will be leakage, this just causes has to repeatedly stop test in whole process of the test, only has and could continue test after again tightening up outer press cover compresses seal elimination gap.Therefore this pressure testing device is adopted, although the object of test tubing being carried out explosion also can be reached after repeatedly tightening up gland, but because test midway repeatedly stops test, thus its result of the test can not meet after on-test in 60 ~ 70 seconds, tested tubing is reached the standard-required of explosion.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of pressure testing device checking tubing, and this pressure testing device can be used for the pressure testing inspection of steel-plastic composite pipe, can detect limiting pressure when tubing reaches explosion within the time of standard-required.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: comprise strip base, the respectively symmetrical pressure testing baffle plate being arranged on base two ends, two described pressure testing baffle plates offer respectively the limit opening moved horizontally to limit tubing for clamping pipe end hermetically-sealed construction overcoat end pipe, the width of this limit opening is less than the external diameter of overcoat and pressure testing baffle plate inner face is close to overcoat outer face.
Also be provided with the cylinder lever connecting rod be positioned at above tubing between two described pressure testing baffle plates, the two ends of described cylinder lever connecting rod are connected with the top of two pressure testing baffle plates respectively.
The quantity of described cylinder lever connecting rod is two, and the end of these two cylinder lever connecting rods is connected with the top of pressure testing baffle limiting opening both sides respectively.
Described base is elongate holes for installing the installing hole of pressure testing baffle plate, and described elongate holes is arranged on two ends or one end of base.
Pressure testing device of the present utility model is by after the two ends of strip base arrange pressure testing baffle plate respectively, utilize the limit opening on pressure testing baffle plate, the tubing that two ends are provided with hermetically-sealed construction just can utilize the end pipe that puts outside hermetically-sealed construction and be installed on pressure testing baffle plate and move horizontally to limit tubing, add that the width of limit opening is less than the external diameter of overcoat and pressure testing baffle plate inner face presses overcoat outer face, that is pressure testing baffle plate can play hermetically-sealed construction and well keep out effect, like this when checking, the hermetically-sealed construction being subject to pressure influence in tubing can there will not be loosening phenomenon under the effect of keeping out of pressure testing baffle plate, can its effect of effective guarantee, there will not be Leakage Gas phenomenon, thus limiting pressure when can detect within the time of standard-required that tubing reaches explosion.And the pressure testing device compact overall structure of inspection tubing of the present utility model, rationally, parts are few, simple for structure, easy to make, and cost is low.
Further, also be provided with the cylinder lever connecting rod be positioned at above tubing between two described pressure testing baffle plates, the two ends of described cylinder lever connecting rod are connected, after cylinder lever connecting rod is arranged with the top of two pressure testing baffle plates respectively, two pressure testing baffle plates are formed connect, what further increase two pressure testing baffle plates keeps out effect.
Further, the quantity of described cylinder lever connecting rod is two, the end of these two cylinder lever connecting rods is connected with the pressure testing baffle plate top of limit opening both sides respectively, and two is preferred amount, and that neither causes excessive setting at utmost can play again pressure testing baffle plate keeps out effect.
Further, described base is elongate holes for installing the installing hole of pressure testing baffle plate, described elongate holes is arranged on two ends or one end of base, and elongate holes adjustable pressure testing baffle plate installation site adapts to the pressure testing inspection of the tubing of different length to regulate the spacing of two pressure testing baffle plates.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the pressure testing device of the utility model inspection tubing.
Shown in the utility model figure: 1 base, 1.1 installing holes, 2 pressure testing baffle plates, 2.1 limit opening, 2.2 support levels, 3 tubing, 4 overcoats, 4.1 end pipes, 5 cylinder lever connecting rods.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, the pressure testing device of inspection tubing of the present utility model, comprises strip base 1, the respectively symmetrical pressure testing baffle plate 2 being arranged on base 1 two ends.Two described pressure testing baffle plates 2 offer respectively the limit opening 2.1 for clamping tubing 3 end seal structure overcoat 4 end pipe 4.1.The width of this limit opening 2.1 is less than the external diameter of overcoat 4 and pressure testing baffle plate 2 inner face presses overcoat 4 outer face.Two pressure testing baffle plates are symmetrical arranged, and the limit opening offered also is symmetrical arranged, such tubing is just installed on two pressure testing baffle plates by limit opening, thus restriction tubing moves horizontally, simultaneously two pressure testing baffle plates press overcoat outer face because of inner face, add that the width of limit opening 2.1 is less than the external diameter of overcoat 4, such two pressure testing baffle plates just can play to the hermetically-sealed construction at tubing two ends the effect of keeping out.
As the improvement project of the present embodiment, be also provided with the cylinder lever connecting rod 5 be positioned at above tubing 3 between two described pressure testing baffle plates 2, the two ends of described cylinder lever connecting rod 5 are connected with the top of two pressure testing baffle plates 2 respectively.And in the present embodiment, the quantity of described cylinder lever connecting rod 5 is two, the end of these two cylinder lever connecting rods 5 is connected with pressure testing baffle plate 2 top of limit opening 2.1 both sides respectively.
For installing the installing hole 1.1 of pressure testing baffle plate 2 for elongate holes on described base 1, described elongate holes is arranged on two ends or one end of base 1.Elongate holes is arranged in the one or both ends of base can be determined for demand, and both arrange the adjustment of the spacing that all can realize two pressure testing baffle plates, thus make the pressure testing device of inspection tubing of the present utility model can check the tubing of different length, expand test range.
In addition, for better supporting whole tubing, the bottom of described pressure testing baffle plate is also provided with the support level 2.2 of the overcoat 4 for supporting hermetically-sealed construction, after this support level 2.2 is arranged, just can effectively support whole tubing.
