Description
(1) technical field
The utility model relates to a kind of tensimeter check-out console.
(2) background technology
Pressure meter calibration stand is a kind of device that the tensimeter of new production is tested, comprise storage tank and pressure vessel, pressure vessel is communicated with efferent duct, be connected with tested table and standard scale on the efferent duct, existing pressure meter calibration stand is manually operated, go out to enter into the oil pressure in the oil storing tube in the pressure vessel by pressing depression bar, fill water in the pressure vessel, after oil is pressed in the pressure vessel, water also is forced out thereupon, flow in tested table and the standard scale and compare detection, tested table and standard scale contrast carrying out manual synchronizing.The shortcoming that existing this pressure meter calibration stand also exists is: 1. manual operation inefficiency, the pressure of the oil of extrusion can only be controlled with experience, is difficult to reach accurate control.2. oil and water mix in the pressure vessel, can only lean on the oil and the density difference of water to make oil and water stratification, oil is on the upper strata, water is in lower floor, efferent duct extend into water is exported by efferent duct simultaneously, but be difficult to guarantee not have oil output, will exert an influence to manometric service property (quality) in case oil enters into tensimeter.
(3) utility model content
Be difficult to accurately to control output pressure in order to overcome existing pressure meter calibration stand, can exert an influence tested manometric service property (quality), the deficiency of inefficiency, the utility model provides a kind of can accurately control output pressure, that can not exert an influence to the service property (quality) of tested table, high efficiency tensimeter check-out console.
The technical scheme in the invention for solving the technical problem is: a kind of pressure meter calibration stand, comprise storage tank, also comprise high-pressure oil pump, profit isolator, described high-pressure oil pump is connected with described storage tank by oil inlet pipe, described oil-water separator comprises an airtight liquid container, be provided with corrugated tube longitudinally in the described liquid container, this corrugated tube is divided into the appearance oil pocket of bottom and the water containing chamber on top with described liquid container, accommodates water in the described water containing chamber; Described high-pressure oil pump is communicated with the appearance oil pocket of described profit isolator by petroleum pipeline, is provided with adjustable level pressure surplus valve and unidirectional inlet valve on the described petroleum pipeline successively, and described adjustable level pressure surplus valve is communicated with described storage tank by surge pipe; The water containing chamber of described profit isolator is communicated with efferent duct, is connected with standard scale and tested table on the described efferent duct.
Further, on the flow direction of oil, the rear of described unidirectional inlet valve is provided with scavenge pipe, and described scavenge pipe is provided with unidirectional oil return valve.
The utility model is at first set the pressure that passes through of adjustable level pressure surplus valve in use, and this pressure equals detected pressures.By high-pressure oil pump the oil in the storage tank is released, oil is transported in the appearance oil pocket of liquid container by petroleum pipeline.In course of conveying, in case oil pressure surpasses the pressure that passes through of adjustable level pressure surplus valve, then unnecessary oil is carried back storage tank by surge pipe, make oil pressure keep stable.After oil was transported to and holds in the oil pocket, the oil pressure of generation was applied on the corrugated tube hydraulic pressure in the water containing chamber is gone out, and was delivered to tested table and standard scale compares detection, tested table and standard scale contrast carrying out manual synchronizing by efferent duct.
The beneficial effects of the utility model are: by the high-pressure oil pump transferring oil, realized automation mechanized operation, the efficient height 1..2. liquid container is divided into it water containing chamber and holds oil pocket by corrugated tube, makes oil and water separation, carry out timing oil and can not enter in the tensimeter, so the utility model can not exert an influence to the service property (quality) of tested table.3. petroleum pipeline is provided with adjustable level pressure surplus valve, can accurately set the output detected pressures.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model
(5) embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, a kind of pressure meter calibration stand comprises storage tank 1, also comprises high-pressure oil pump 2, profit isolator 3, and described high-pressure oil pump 2 is connected with described storage tank 1 by oil inlet pipe 4.
Described oil-water separator 3 comprises an airtight liquid container, be provided with corrugated tube 5 (being that pipe is provided with the rubber-like pipe that laterally inwardly caves in) longitudinally in the described liquid container, this corrugated tube 5 is divided into the appearance oil pocket 6 of bottom and the water containing chamber 7 on top with described liquid container, accommodates water in the described water containing chamber 7.
Described high-pressure oil pump 2 is communicated with the appearance oil pocket 6 of described profit isolator by petroleum pipeline 8, is provided with adjustable level pressure surplus valve 9 and unidirectional inlet valve 10 on the described petroleum pipeline 8 successively, and unidirectional inlet valve 10 can only be flowed oil by high-pressure oil pump to holding the oil pocket direction.Described adjustable level pressure surplus valve 9 is communicated with described storage tank 1 by surge pipe 11; The water containing chamber 7 of described profit isolator is communicated with efferent duct 12, is connected with standard scale 13 and tested table 14 on the described efferent duct 12.
