Abstract
The invention relates to a hydraulic pressure tester for a pipe fitting, and in particular relates to a pipe fitting applicable to DN1600-2200. In the tester, a fixed parapet is fixed on the right end of a base, a fixed wall block is arranged on the left end of the fixed parapet, and the central hole of the fixed wall block is communicated with a fixed water valve via a pipeline; the left end of the base fixes the movable parapet via a guide rail and a fastening device, an oil cylinder is fixed on the movable parapet, a push head is fixed on the left end of the actuating arm of the oil cylinder, the left end of the push head is fixed on the movable parapet, and the central hole of the movable wall block is connected with a movable water valve via a pipe. A dolly and a dolly-lifting device are configured on the base between the fixed parapet and the movable parapet. The tester has high efficiency and is safe and reliable.
Description
Technical field
The present invention relates to a kind of pipe fitting hydrostatic testing machine, the pipe fitting of particularly suitable DN1600-2200.
Background technology
For quality and the mechanical property that guarantees the cast carbon steel pipe fitting, cast iron pipe fittings must be one by one in accordance with regulations pressure carry out the hydraulic testing, but do not have the pipe fitting hydrostatic testing machine of DN1600～2200 now.
Summary of the invention:
In order to overcome the shortcoming of prior art, the invention provides a kind of pipe fitting hydrostatic testing machine, its efficient height, safe and reliable.
The present invention solves the technical scheme that its technical matters takes: the fixing fixedly barricade of the right-hand member of base, and fixedly the left end of barricade has fixedly that wall blocks up, and fixedly the center pit that blocks up of wall communicates with fixing water valve by pipeline; The left end of base is fixed movable barricade by guide rail, locking device, fixed oil cylinder on the movable barricade, and the right-hand member of hydraulic oil cylinder driving arm is fixedly cut somebody's hair, and the fixing movable wall of the right-hand member of cutting somebody's hair is stifled, and the stifled center pit of described movable wall communicates with movable water valve by pipeline; Fixedly dolly and dolly lifting device on the base between described fixedly barricade and the movable barricade.
The present invention can carry out the hydraulic testing to the pipe fitting of DN1600-2200, and the efficient height is safe and reliable.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
Embodiment
As shown in drawings, the fixing fixedly barricade 10 of the right-hand member of base 11, fixedly the left end of barricade 10 has fixedly that wall blocks up 9, and fixedly wall blocks up 9 center pit and communicates with fixing water valve 8 by pipeline; The left end of base 11 is by guide rail, the fixing movable barricade 2 of locking device, fixed oil cylinder 1 on the movable barricade 2, the right-hand member of oil cylinder 1 actuating arm fixedly cuts somebody's hair 4, and the fixing movable wall of 4 the right-hand member of cutting somebody's hair is stifled 5, and the center pit of described movable wall stifled 5 communicates with movable water valve 3 by pipeline; Fixedly dolly 13 and dolly lifting device 12 on the base 11 between described fixedly barricade 10 and the movable barricade 2.
The described supporting mechanism that be to float of cutting somebody's hair, there is stronger adaptability in this mechanism, and no matter which kind of reason causes the deviation of pipe fitting putting position, can be effectively with movable wall stifled 5 and pipe fitting 6 sealings.
Fixing between described fixedly barricade 10 and the movable barricade 2 with pull bar 7.Described pull bar 7 is three sections, and each section is by being threaded.For weight reduction, the material of pull bar 7 is a thick-walled seamless steel pipes.Described pull bar 7 has 6.
During use, pipe fitting 6 is sent into the working position by dolly 13, rises to working depth by dolly lifting device 12.Oil cylinder 14 is pressed on pipe fitting 6 between movable end stifled 5 and the stiff end stifled 9 by cutting somebody's hair, and opens movable water valve 3, fixing water valve 8 then, water filling in pipe fitting 6.Fills with water and with after the air emptying in the pipe fitting 6 start high pressure water system, and hydraulic pressure is risen to the pressure of regulation, after pressurize a period of time, are generally 15 seconds.Discharge water then, pipe fitting 6 descends and delivers to next station and gets final product.
