Description
Technical field
The utility model relates to a kind of hydraulic testing hydraulic floating end socket, belongs to ductile iron pipe hydraulic testing technical field of sealing technology.
Background technology
The program of producing of ductile iron pipe very important is the hydraulic testing, and the way adopted at present blocks pipe both sides with sealing gasket, fills water under high pressure to certain pressure and pressurize, do not have leakage to be qualified to tube interior.Existing equipment is that female end sealing station is fixed, and socket end can move forward and backward, and realizes the compression of pipe and unclamps.In this operation, in order to make to hold, the sealing gasket of socket both sides reaches sealing effectiveness, needs impose severe pressure, the master cylinder band dynamic sealing assembly of socket end is implemented move forward and backward and provide preload pressure, but the pressure demand of needs during high-pressure flush cannot be met, devised hydraulic pressure for this reason at that time and to float the design of end socket.Be specially spigot seal pad to be arranged on two ends and to have on the piston of difference in areas, hollow, the area of piston both sides different and with the outlet contacts of pressure testing pipe, during high pressure water-filling, the hydraulic pressure at piston two ends is identical, but outside area is large, the thrust therefore outside piston is greater than inner side, and piston applies the pressure outside oil cylinder preload pressure to pipe, meet the pressure requirements of gasket seal needs, realize sealing.This hydraulic pressure end socket mode Problems existing that floats is: 1, an end socket only has a piston, can not meet the demand of present plurality of specifications pipe bulge test simultaneously, cannot meet the needs producing now many specifications pipe.2, the hydraulic pressure water quality of floating in end socket is poor, has the impurity such as iron filings, and easily damage piston seal and seized piston, failure rate is high.3, the end socket that floats gets rusty to prevent, and material mostly is stainless steel, and volume is comparatively large, and processing cost is higher.
Summary of the invention
For the defect of prior art, the utility model provides a kind of and adapts to multiple different size cast carbon steel, failure rate is low, cost is low, efficiency is high hydraulic testing hydraulic floating end socket.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hydraulic testing hydraulic floating end socket, comprise master cylinder, coupling arrangement, be connected to the floating cylinder of main oil cylinder piston bar front end by coupling arrangement, the front end of floating cylinder piston rod is connected with the rebasing plate of combination sealing, the rebasing plate of combination sealing is provided with multiple sealing gasket being applicable to different size cast carbon steel, be equipped with by pipeline below each sealing gasket and be positioned at the gas exhaust piping that the startup valve on pipeline forms, described gas exhaust piping composes in parallel drain tap group.
Further, the rebasing plate of described combination sealing is provided with multiple ring groove, and sealing gasket is positioned at ring groove.
Further, described coupling arrangement is web joint or flange.
Further, the quantity of described sealing gasket and gas exhaust piping is 2-6.
Further, described floating cylinder is the oil cylinder of large-diameter, short stroke, the pressure of oil cylinder is controlled by proportional pressure control valve, when can suppress according to different size cast carbon steel need thrust and automatic pressure regulation, to meet the demand that different size cast carbon steel is produced at same product line.
The beneficial effects of the utility model: the rebasing plate of combination sealing described in the utility model is provided with the sealing gasket of multiple different-diameter, can adapt to the cast carbon steel of multiple different size; The rebasing plate of combination sealing is by Driven by Hydraulic Cylinder, and the diameter of hydraulic cylinder and required pressure are by calculating, and during work, passing ratio hydraulic valve automatic pressure regulation realizes the pressure demand that different size suppresses pressure testing; High, the easy maintenance of making precision of oil cylinder and can reliable control polluted articles, failure rate is low, hydraulic pressure end socket machining precision of floating can be avoided low, and quality of fit is not easy to grasp, the problem that in use procedure, impurities in water causes bad seals and blocks.By improving, different size cast tube can be realized and produce at same production line, enhancing productivity, hydraulic pressure can be reduced simultaneously and to float the high problem of end socket failure rate.
