Description
Technical field
The utility model belongs to hydrostatic testing machine field, particularly relates to a kind of pressure charging system of hydrostatic testing machine.
Background technology
In water pressure engine pressure charging system, supercharging mode is mainly: by charger boost (also known as built-in supercharger), in steel pipe, inject these two kinds of modes of water under high pressure supercharging (also known as external supercharger).The former can reach higher pressure, but the stroke of supercharger is longer.Rear a kind of mode, when pressure test pressure raises, requires higher to the operation valve on water route and pipeline, adds the cost of equipment.And in the production run of reality, when the pressure test pressure of steel pipe requires to change greatly, a water pressure engine cannot reach the requirement of production.
Summary of the invention
The utility model provides a kind of pressure charging system that can ensure the hydrostatic testing machine that increase process is steadily carried out for solving in known technology the technical matters that exists.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
A kind of pressure charging system of hydrostatic testing machine, comprise water pot and water intaking valve, first water inlet of described water pot is communicated with described water intaking valve, it is characterized in that: described water pot has two water delivering orifices, two described water delivering orifices are communicated with the second outlet valve with the first outlet valve respectively, the outlet of described first outlet valve and external supercharger, the outlet of described external supercharger is also communicated with the first retaining valve of the water inlet direction one-way conduction along external supercharger, second retaining valve of unloader and the water outlet direction one-way conduction along external described supercharger, the other end of described second retaining valve is communicated with the first water inlet of filling device, also pressure transducer is provided with between described second retaining valve and described filling device, second outlet valve is communicated with the second water inlet of described filling device, second water inlet of described filling device is provided with filling valve, built-in supercharger is also provided with in filling device.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, built-in supercharger is combined with external supercharger, filling device adds the path of water under high pressure, this path is connected with external supercharger, has installed retaining valve and unloader on water under high pressure pipeline simultaneously.Ensure that water under high pressure can not be played a reversed role water return tank and external supercharger, available protecting water lines by arranging two retaining valves.Unloader is used for carrying out off-load to the water under high pressure in water under high pressure pipeline.There is also mounted pressure transducer at water-filling path, by pressure sensor monitoring overpressure, control the conversion of supercharging mode, ensure that pressurization is steadily carried out; Meet the requirement to different pressures, effectively raise work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, water intaking valve; 2, water pot; 3, the second outlet valve; 4, the second inlet pipeline; 5, pressure testing steel pipe; 6, filling device; 7, filling valve; 8, built-in supercharger; 9, unloader; 10, pressure transducer; 11, the second retaining valve; 12, water under high pressure pipeline; 13, external supercharger; 14, the first retaining valve; 15, the first inlet pipeline; 16, the first outlet valve.
Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of pressure charging system of hydrostatic testing machine, comprise water pot 2 and water intaking valve 1, first water inlet of water pot is communicated with water intaking valve, water pot has two water delivering orifices, two water delivering orifices are communicated with the second outlet valve 3 with the first outlet valve 16 respectively, first outlet valve is by the first inlet pipeline 15 and along water inlet direction one-way conduction first retaining valve 14 of external supercharger and the outlet of external supercharger 13, the outlet of external supercharger is also communicated with the second retaining valve 11 of unloader 9 and the water outlet direction one-way conduction along external supercharger, the other end of retaining valve is communicated with the first water inlet of filling device 6, pressure transducer 10 is also provided with between the second retaining valve 11 and filling device, second outlet valve 3 is communicated with the second water inlet of filling device by the second inlet pipeline 4, second water inlet of filling device is provided with filling valve 7, filling valve blocks or gets through the pipeline being carried out water-filling by the second water inlet to filling device, built-in supercharger 8 is also provided with in filling device.
Operating principle of the present utility model is:
During pressure testing, first pass through filling valve 7 to water-filling in pressure testing steel pipe 5, after water-filling terminates, supercharging is carried out to the water in steel pipe.When the pressure test pressure required is low, directly by the supercharging of external supercharger 13, second retaining valve 11 can not to be played a reversed role back external supercharger 13 for ensureing water under high pressure, first retaining valve 14 can not to be played a reversed role water return tank 2 for ensureing water under high pressure, and unloader 9 is for carrying out off-load to the water under high pressure in water under high pressure pipeline 12.When the pressure test pressure height required, first by the supercharging of external supercharger 13, when reaching certain pressure test pressure, again by the supercharging of built-in supercharger 8, thus reaching higher test pressure, such structure had both reduced the requirement to water circuit system, also effectively can shorten the stroke of built-in supercharger.Pressure transducer 10 for monitoring overpressure, thus controls the conversion of supercharging mode, ensures that pressurization is steadily carried out.This pressure charging system pressure testing even pace, meets different steel pipe pressure demand, effectively raises work efficiency.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
