Abstract
The utility model brings forward a pressure resistance test system of a pressure gauge. An oil delivery pipe is communicated with an oil cylinder and an oil pump. A plurality of sets of parallel oil paths are arranged on the front end of the oil delivery pipe. Each set of oil path is provided with a pressure increasing valve. The front end of each set of oil path is equipped with a joint that is cooperated with a pressure gauge. The pressure resistance test system of a pressure gauge is simple in structure and easy in use, and can be conveniently used for the pressure resistance test of the pressure gauge.
Description
Technical field
The utility model relates to a kind of manometric proving installation, particularly a kind of tensimeter pressure-resistant test system.
Background technology
In the prior art, manometric application more and more widely, particularly during the use under some extreme environments; Requirement to manometric usability is also just increasingly high; Yet some tensimeters that roll off the production line only promptly put goods on the market through the simple pressure test of short time, and manometric long-term use possibly cause the tensimeter correlated performance to descend; Make tensimeter that certain potential safety hazard in use take place; And do not exist a kind of device that can the durable pressure of test pressure table, potential safety hazard to be difficult to get rid of in the prior art, need to be resolved hurrily.
The utility model content
The utility model provides a kind of simple in structure, tensimeter pressure-resistant test system of being easy to use, can carry out tensimeter very easily voltage-withstand test.
The utility model solves the problems of the technologies described above through following technical scheme; The utility model proposes a kind of tensimeter pressure-resistant test system; Petroleum pipeline is communicated with oil cylinder and oil pump forms working connection; Working connection forms many branch oil circuits through solenoid control, and every branch oil circuit is provided with independently pressure charging valve, every said manometric joint of cooperation that branch oil circuit front end is provided with some parallel connections.
Preferably, the joint front end is provided with plug.
Preferably, also comprise control panel, said control panel is controlled said tensimeter oil pressure value and voltage-withstand test time through the control pressure charging valve, the break-make that said control panel divides oil circuit through control electromagnetic valve control.
Preferably, oil cylinder and oil pump all are installed in the shell.
Based on disclosing of above technical scheme, the utlity model has following beneficial effect:
This apparatus structure is simple, is easy to use, and can carry out voltage-withstand test to tensimeter very easily.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structure diagram of embodiment 1 in the utility model;
1, shell; 2, oil cylinder; 3, oil pump; 4, petroleum pipeline; 41, working connection; 42, divide oil circuit; 5, solenoid valve; 6, pressure charging valve; 7, joint; 8, plug.
Embodiment
Following embodiment and Fig. 1 of combining is described further the utility model:
A kind of tensimeter pressure-resistant test system; Petroleum pipeline 4 is communicated with oil cylinder 2 and forms working connection 41 with oil pump 3; Working connection 41 forms many branch oil circuits 42 through solenoid valve 5 controls; Every branch oil circuit 42 is provided with independently pressure charging valve 6, every said manometric joint 7 of cooperation that branch oil circuit 42 front ends are provided with some parallel connections.Oil cylinder 1 all is installed in the shell 1 with oil pump 3.
The enforcement of following combination the utility model is described further the utility model:
With tensimeter jointing 7, by oil pump 3 power is provided, the oil in the oil cylinder 2 is passed through in the petroleum pipeline 4 pump-in pressure tables; And the time of passing through pressure charging valve 6 controlled pressure table oil pressure values and withstand voltage test; In present embodiment 1, working connection 41 is through solenoid valve 5 control and form many branch oil circuits 42, and by solenoid valve 5 to each minute oil circuit 42 break-make control; Different branch oil circuits 42 all is provided with independently pressure charging valve 6; Oil pressure through in pressure charging valve 6 pairs of these minutes oil circuit 42 is controlled, because the existence of solenoid valve 5, makes each minute oil circuit 42 independently of one another; And independently voltage-withstand test can be provided; Because every manometric joint 7 of cooperation that branch oil circuit 42 front ends all are provided with some parallel connections also makes same branch oil circuit 42 to detect a plurality of tensimeters simultaneously, forms one and can export the detection system that multiple different oil pressure data detect tensimeter.
Based on embodiment 1, form embodiment 2 through the technical characterictic that increases an optimization.Wherein, the technical characterictic of optimization is following:
Joint 7 front ends are provided with dismountable plug 8.
When carrying out withstand voltage test,, can avoid 7 pairs of these joints of this joint, 7 places to divide other joints 7 of oil circuit 42 to impact through plug 8 being installed with these joint 7 sealings if one of them joint 7 need not be used.
Based on embodiment 1, form embodiment 3 through the technical characterictic that increases an optimization.Wherein, the technical characterictic of optimization is following:
Also comprise control panel, control panel is through control pressure charging valve 6 controlled pressure table oil pressure values and voltage-withstand test time, and control panel is through the break-make of control electromagnetic valve 5 control branch oil circuits 42.
Through disclosing of this preferred technical characterictic, make this device convenient in operation.
The utility model is not limited thereto embodiment, and the related realization assembly that is the basis with the utility model thought is all in the protection domain of the utility model.
