In figure, each parts are: 1-inverted welded gas cylinder 2-electro connecting pressure gauge 3-tensimeter 4-by-pass valve control 5-electrodynamic pump 6-experimental tank 7-first pipeline 8-second pipe 9-water return pipeline 10-low-pressure electric pump 10-main pipeline.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, the present embodiment is implemented under premised on technical solutions of the utility model, should understand these embodiments and only be not used in restriction scope of the present utility model for illustration of the utility model.
A kind of gas cylinder steam mixing pressure testing machine as shown in Figure 1, comprise experimental tank 6, high-pressure electric pump 5, low-pressure electric pump 11, by-pass valve control 4 and tensimeter 3, described experimental tank 6 is connected to main pipeline 11 by the first pipeline 7 through high-pressure electric pump 5, by-pass valve control 4, is provided with tensimeter 3 between by-pass valve control 4 and main pipeline 11; Described experimental tank 6 is connected to main pipeline 11 by second pipe 8 through low voltage control pump 10, by-pass valve control 4; Main pipeline 11 is in charge of by each branch road and is connected to the inverted bottle mouth position by air bottle 1, and main pipeline 11 is also connected to experimental tank 6 by water return pipeline 9 and by-pass valve control 4.
Principle of work of the present utility model is: this steam mixing pressure testing machine utilizes pressurized air to be insoluble in water and density is less than the principle of water, bottle oral area is upside down on steam bulk testing platform down, utilize the low-lift pump of a huge discharge to water filling in bottle, bottle inside is boosted to 3 ~ 5MPa, in boost process, checks whether bottle outer surface exists leakage situation; If bottle No leakage, stop low-lift pump running, start high-pressure pump, pressure in bottle is boosted to hydraulic test pressure, checking bottle intensity and sealed bottom performance.
Embodiment 2:
As different from Example 1, by-pass valve control 4 in the present embodiment is motorized valve, electro connecting pressure gauge 2 is also provided with between by-pass valve control 4 and main pipeline 11, test pressure can be controlled like this by electro connecting pressure gauge 2, and control the break-make of motorized valve, realize automatically controlling, carry further and done work efficiency.
This steam bulk testing device, has successfully been used in flame snuffer seamless steel cylinder, respirator seamless steel cylinder and industrial use steel cylinder voltage-withstand test that my company produces, has realized the objective plan that separate unit testing machine day detects 1000 seamless gas cylinders.
Steam mixing pressure testing machine of the present utility model, by traditional voltage-withstand test and air-leakage test comprehensively to mixing pressure testing machine, eliminates air tightness test machine and attached air compressor machine and pipeline, has saved the energy and cost of labor.Owing to eliminating air compressor machine and subsidiary pipeline, the potential safety hazard that the operation objectively decreasing high pressure vessel, pipeline and equipment brings, eliminates the misgivings of workman in safety.
