Abstract
The utility model relates to a multifunctional superhigh pressure test stand, which can test an inverted valve, a high pressure pipeline and a filling pump. The test stand is provided with the convex device of the inverted valve to test the inverted valve and the high pressure pipeline under the condition of the filling pump without leakage.
Description
The present invention relates to a kind of multifunctional superhigh pressure test table, or rather, relate to a kind of being used for to detect the UHV (ultra-high voltage) testing table whether reverse checkvalve, high pressure line and filling pump have leakage at the UHV (ultra-high voltage) pipeline.
At present, the UHV (ultra-high voltage) filling pump testing table that units such as Beijing Yanshan Petrochemical head factory, Kingsoft, Shanghai general petrochemicals factory use can only be tested filling pump singlely, and can't solve the Leak Detection problem of UHV (ultra-high voltage) pipeline and reverse checkvalve.
The object of the present invention is to provide a kind of multi-function test stand, can the leakage situation of reverse checkvalve, high pressure line and filling pump be detected by this testing table.
The object of the present invention is achieved like this, a reverse checkvalve convex device promptly is set on platform, an endpiece of this device links to each other with plug by high pressure line (hereinafter to be referred as pipeline), the other end by pipeline successively with three-way body, the high pressure through way valve, the oil return jar links to each other, first tensimeter is set on the pipeline between oil return jar and the three-way body, the pipeline that stretches out from the oil return jar other end is connected to high-pressure stop valve, end interface is used for connecting with the pipeline that is connected the three-way body upper opening when detecting reverse checkvalve with high pressure line on the filling pump, and the outlet at bottom of filling pump links to each other with storage tank with another high pressure through way valve by pipeline.The pipeline that then will link to each other with three-way body when detecting filling pump unloads and filling pump is linked to each other with manometric joint by pipeline from filling pump.Motor reducer is equipped with in the bottom of platform, and this speed reduction unit is by the actuator drives camshaft, and the tappet that camshaft pushes in the filling pump is in vertical reciprocating motion, and hydraulic oil is compressed in filling pump cylinder cavity, and is discharged to and forms hydraulic oil in the high pressure line.
The invention has the advantages that the leakage situation that can on a testing table, detect multiple parts, testing process is greatly simplified.
Below in conjunction with accompanying drawing most preferred embodiment of the present invention is described in detail.
Fig. 1 is a front view of the present invention;
Fig. 2 is a vertical view of the present invention;
Fig. 3 is the partial cutaway diagrammatic sketch of the used reverse checkvalve convex of the present invention device.
See figures.1.and.2, a reverse checkvalve convex device 7 wherein is set on the platform 12, this installs by screw retention on platform, one end of this convex device by high pressure line 6 successively with three-way body 24, high pressure through way valve 23, oil return jar 3 links to each other, first tensimeter 1 is housed on the pipeline between oil return jar 3 and the three-way body, link to each other with high-pressure stop valve 26 from the pipeline of oil return jar output, the upper end open of filling pump 8 is used for joining with the pipeline that is connected three-way body 24 upper openings when detecting reverse checkvalve with high pressure line, the pipeline that then its upper port is linked to each other with three-way body 24 when detecting filling pump unloads then joins with the pipeline that links to each other with second tensimeter 9, and the bottom of filling pump 8 links to each other with storage tank 2 with another high pressure through way valve 10 by high pressure line.Motor reducer 20 is equipped with in the bottom of platform 12, this speed reduction unit is by sprocket wheel 19, chain 18 drive cam shaft 15, the tappet (not shown) that camshaft 15 pushes in the filling pump 8 is in vertical reciprocating motion, hydraulic oil is compressed in filling pump cylinder cavity, and the equipment of formation hydraulic oil platform 12 bottoms all is contained in the cabinet 14 in discharge pipe.
With reference to Fig. 3, the figure shows the reverse checkvalve convex device that detection UHV (ultra-high voltage) pipeline and reverse checkvalve leakage situation are used.This device endoporus is cylindrical stepped, one transition shoulder 30a is arranged between first order ladder 30 and second level ladder 31, the end of second level ladder 31 is tapered, its cone angle is 120 °, the conical surface is the extra accuracy sealing surface, during detection reverse checkvalve being inserted this hole fits tightly reverse checkvalve socket and sealing surface to be one to form the close formula combination of line.
When detecting reverse checkvalve, reverse checkvalve to be checked is contained in the convex device cavity, connects the discrepancy pipe joint.Open high pressure through way valve 10 and 23, close high-pressure stop valve 26, turn the oil in the storage tank handle (not shown) compression storage tank, make oil enter filling pump by pipeline, open motor reducer, make the oil of sending by filling pump through pipe flow will to the first tensimeter 1, when pressure rises to 180MPa, press the stop key (not shown) on the cabinet, close high pressure through way valve 10, the variation of tensimeter 1 is observed in pressurize 15 minutes, if pressure variation≤0.5MPa, then reverse checkvalve is qualified.Opening reverse checkvalve after the detection makes oil enter oil return jar 3 to discharge through atmospheric valve.
When detecting the UHV (ultra-high voltage) pipeline, plug 27 is tightened, the sealing lifting head that a qualified nothing is leaked in the check valve pocket takes out.The reverse checkvalve of no lifting head is packed in the reverse checkvalve convex device cavity.Open high pressure through way valve 10, close high pressure through way valve 23.Turn the storage tank handle, oil is injected filling pump, the actuating motor speed reduction unit makes oil enter high pressure line until first tensimeter 1 through the reverse checkvalve of no lifting head.When the pressure tabular value rises to 200MPa, press the stop button (not shown), close high pressure through way valve 10,15 fens kinds of pressurize are observed manometric variation.If changing value≤0.5MPa then think that this high pressure line is qualified.Open high pressure through way valve 23 then, make oil flow into the oil return jar, emit through atmospheric valve.
When detecting above-mentioned two parts, at first the pipeline that the filling pump upper end should be used for linking to each other with second tensimeter 9 when detecting filling pump unloads, and this upper interface is joined with the pipeline that links to each other with the three-way body upper port.
Detection to filling pump is identical with prior art, no longer narrates at this.
