The hydraulic press structure for the small-caliber steel pipe realizes sealing of the steel pipe through water pressure by using the ultrahigh-pressure large-clearance sealing ring, and is simple in operation and low in labor intensity of operators. Moreover, pressure stability can be guaranteed, and better test effect can be achieved.
Description
Technical field
The utility model relates to a kind of water pressure engine, the water pressure engine structure that particularly a kind of small-caliber steel pipe uses.
Background technology
In the production run of steel pipe, mainly adopt water pressure engine that steel pipe is carried out withstand voltage test, the end with steel pipe blocks exactly, injects water under high pressure then in steel pipe steel pipe is carried out withstand voltage test.The basic functional principle of water pressure engine is a Pascal law, utilizes water to be actuating medium, carries out work with the static pressure transmission.Existing water pressure engine generally comprises water circuit system and oil piping system two parts, when water circuit system is responsible for steel pipe and is carried out hydrostatic test in steel pipe water-filling suppress, the control end socket was realized the pressure equilibrium of pipe end profit when oil piping system was responsible for Pipe Hydrostatic Test.
Present water pressure engine adopts the end socket of oil piping system control steel pipe to come the shutoff steel pipe, unusual complexity operates, working strength of workers is bigger, and adopt oil piping system control end socket for small-caliber steel pipe, to exist the problem of pressure transient, thereby can cause adverse influence to the withstand voltage test of steel pipe.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model is a small-caliber steel pipe water pressure engine structure simple to operate, pressure stability.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of small-caliber steel pipe water pressure engine structure, comprise a steel pipe, one end of described steel pipe is connected with the water-filling high-pressure hydraulic pump by pipeline, the other end of described steel pipe is provided with the big clearance seal circle of a UHV (ultra-high voltage), the big clearance seal circle of described UHV (ultra-high voltage) is connected with a sealed high pressure water pump, the big clearance seal circle of described UHV (ultra-high voltage) also is connected with a supercharge pump, and the big clearance seal circle of described UHV (ultra-high voltage) is provided with retaining valve and solenoid valve with the pipeline that described sealed high pressure water pump, supercharge pump are connected.
Preferably, described steel pipe is positioned at a V-type and clamps on the dolly, and described V-type clamps dolly and is provided with two V-blocks, and described steel pipe clamps by described two V-block centerings.
Technique scheme has following beneficial effect: this small-caliber steel pipe water pressure engine structure is not when working, big clearance seal circle of UHV (ultra-high voltage) and steel pipe separate a fixed gap, when carrying out withstand voltage test, supply water to the big clearance seal circle of UHV (ultra-high voltage) by sealed high pressure water pump and supercharge pump, sealed of big clearance seal circle of UHV (ultra-high voltage) and steel pipe are closely contacted make steel pipe sealing, then by filling water under high pressure in the water-filling high-pressure hydraulic pump shape steel tube, steel pipe is carried out withstand voltage test, should guarantee the sealing load of the big clearance seal circle of UHV (ultra-high voltage) and the hydraulic pressure pressure equilibrium in the steel pipe in the process of the test.This small-caliber steel pipe water pressure engine structure uses the big clearance seal circle of UHV (ultra-high voltage) to provide pressure to make steel pipe sealing by water, and is simple to operate, labor intensity of operating personnel is little, and can guarantee the stable of pressure, can play better test effect.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the water supply line synoptic diagram of the big clearance seal circle of the utility model embodiment UHV (ultra-high voltage).
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, 2, this small-caliber steel pipe water pressure engine structure comprises a steel pipe 1, steel pipe 1 is positioned at a V-type and clamps on the dolly 3, V-type clamps dolly 3 and is provided with two V-blocks, steel pipe 1 clamps by two V-block centerings, so just greatly increase device ', prevented the bending of steel pipe 1 in the pressure testing process.One end of steel pipe 1 is connected (not shown) by pipeline with the water-filling high-pressure hydraulic pump, and the other end of steel pipe 1 is provided with the big clearance seal circle 2 of a UHV (ultra-high voltage), and the big clearance seal circle 2 of UHV (ultra-high voltage) is connected with a sealed high pressure water pump 4 and a supercharge pump 5.For the ease of control hydraulic pressure, the big clearance seal circle 2 of UHV (ultra-high voltage) is provided with solenoid valve 41, retaining valve 42, surplus valve 43 and unloads pressure electromagnetic valve 44 with the connecting tube of sealed high pressure water pump 4, and the pipeline that the big clearance seal circle 2 of UHV (ultra-high voltage) is connected with supercharge pump 5 is provided with retaining valve 52 and solenoid valve 51.
This small-caliber steel pipe water pressure engine structure is not when working, and the big clearance seal circle 2 of UHV (ultra-high voltage) separates a fixed gap with steel pipe 1.When carrying out withstand voltage test, supply water to the big clearance seal circle 2 of UHV (ultra-high voltage) by sealed high pressure water pump 4, and the pressure by supercharge pump 5 control water, make the big clearance seal circle 2 of UHV (ultra-high voltage) make steel pipe sealing with sealed tight contact of steel pipe 1, then by filling water under high pressure in the water-filling high-pressure hydraulic pump shape steel tube 1, steel pipe is carried out withstand voltage test, should guarantee the sealing load of the big clearance seal circle 2 of UHV (ultra-high voltage) and the hydraulic pressure pressure realization mobile equilibrium in the steel pipe 1 in the process of the test.Too big as hydraulic pressure, then can squeeze and hinder steel pipe; Too little as sealing load, then can cause steel pipe sealing to lose efficacy, can cause the water under high pressure ejection that equipment and personnel are on every side brought security risk when serious,
This small-caliber steel pipe water pressure engine structure uses the big clearance seal circle of UHV (ultra-high voltage) to provide pressure to make steel pipe sealing by water, and is simple to operate, labor intensity of operating personnel is little, and can guarantee the stable of pressure, can play better test effect.
More than a kind of small-caliber steel pipe water pressure engine structure that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
