Abstract
The utility model relates to a hydrostatic testing apparatus for steel sheet coiled pipes which is suitable for the major diameter flat weld bead with the diameter from 0.6 metres to 2.5 metres. The hydrostatic testing apparatus for steel sheet coiled pipes mainly comprises a hydraulic system, a water supply and drainage system and a positioning device. The hydraulic system is composed of an oil pump, an oil pipe, a distributor and an oil top. The water supply and drainage system is composed of a charging pump, a water inlet pipe, a water discharge pipe and a hydraulic test pump. The positioning device is composed of a fixed housing window, a movable housing window, a cross beam, a bottom plate, etc. The utility model has the advantages of convenient operation, good tightness and self aligning, and is particularly suitable for the hydrostatic test of a lot size of steel pipes.
Description
The utility model is a kind of improved steel pipe hydrostatic testing device, particularly a kind of pressure testing device that is applicable to the straight weld seam plate rolling tube of major diameter.
The general employing of existing steel tube pressure-measuring adds end cap at the steel pipe two ends, and water pump injects water by water inlet pipe and carries out the hydraulic testing in steel pipe, and not only efficient is low, the continuous production and the pressure testing of incompatibility steel pipe, and often because of the poorly sealed leakage phenomenon that produces.
The purpose of this utility model is that design a kind ofly can be adjusted end sealing automatically, guarantees that pressure testing do not leak, and is applicable to the water test unit of checking the straight weld seam plate rolling tube of major diameter in batches.
The purpose of this utility model is achieved in that and hydraulic system that a cover is made up of oil pump, oil pipe, divider, oil top etc. is set and by base plate, crossbeam, the fixing locating device formed such as memorial archway, movable memorial archway on the basis of the supply and drain water system of being made up of water pump, water inlet pipe, drainpipe, an end face of movable memorial archway is hinged with the sphere on oil top, O-ring seal then is equipped with in the other end, even the end face of plate rolling tube is not too parallel like this, also can reach the purpose of automatic capturing, sealing without leakage during pressure testing.
The utility model is simple in structure, uses reliably, is the indispensable device of large-diameter steel plate pipe crimping quality inspection.
The plate rolling tube water test unit of the utility model being carried below in conjunction with accompanying drawing is further described:
Fig. 1 is the synoptic diagram that the utility model is carried the plate rolling tube water test unit.
Fig. 2 is the synoptic diagram of A among Fig. 1.
From Fig. 1, can find out among Fig. 2 that the plate rolling tube water test unit mainly comprises by oil pump 1, oil pipe 2, the hydraulic system that divider 3 oil tops 10 grades are formed, by charging pump 4, test pump 5, water inlet pipe 6, the supply and drain water system that drainpipe 7 is formed, with by base plate 8, right fixedly memorial archway 9, movable memorial archway 11, a left side is memorial archway 12 fixedly, rail 13, guide rail 14, road wheel 15, locating device three parts that crossbeam 16 grades are formed, a left side, right fixedly memorial archway 12,9, crossbeam 16, base plate 8 forms a general frame, oil top 10 is installed on the right fixedly memorial archway 9, and logical spherical articulated (not drawing among the figure) links to each other with an end face of movable memorial archway 11, O-ring seal is equipped with in the left side of movable memorial archway 11, O-ring seal (all not drawing in the sealing loop graph) also is equipped with on a left side fixedly right side of memorial archway 12, but this activity memorial archway 11 is by road wheel 15 move left and right on guide rail 14, as long as will treat the plate rolling tube of pressure testing puts on movable memorial archway 11 and the left fixedly rail between the memorial archway 12 13, start oil pump 1, hydraulic oil makes 10 work of oil top by oil pipe 2 through divider 3, push movable memorial archway 11 left, make plate rolling tube B and O-ring seal driving fit and pass through the globular hinge automatic capturing, controlling best oil pressure as required makes sealing be in optimum condition, start charging pump 4 fills with water and be pressurized to test pressure in plate rolling tube B then by test pump 5 classifications, check the tightness of weld seam, release then discharges water, start oil pump 1 movable memorial archway 11 is return original position, to try good plate rolling tube B then and roll away, just can carry out pressure testing next time.
Claims (3)
1, plate rolling tube water test unit of being made up of charging pump 4, test pump 5, water inlet pipe 6, drainpipe 7 is characterized in that:
A. be provided with the hydraulic system of forming by oil pump 1, oil pipe 2, divider 3, oil top 10 etc.
B. be provided with the locating device of forming by left and right fixedly memorial archway 12,9, movable memorial archway 11, crossbeam 16, base plate 8, road wheel 15, guide rail 14 etc.
