Abstract
The utility model discloses an on-line automatic sampler for a pipe line, especially suitable for sampling the piped liquid of the petroleum industry and the chemical industry. The utility model comprises a hydraulic station, an automatic control system and an electromagnetic valve. The electromagnetic valve is used for controlling a hydraulic cylinder to make a piston move in a piston cylinder body in a reciprocating way to drive a piston plunger to extract the liquid in the pipe line into a sample oil chamber, intermittent automatic continuous sampling can be conducted through a liquid sucking and discharging tube arranged on the sample oil chamber body and the sampling time and sampling amount can be set according to the operation condition of the liquid pipe line. The sampling is free from the interference of artificial factors, so the sampled oil sample is uniform and steady and the sample is more representative and just.
Description
The utility model relates to the on-line automatic sampler of liquid line, is particularly useful for the pipeline transportation liquid sampling of oil, chemical industry.
Current oil, the fluid product pipeline transportation of chemical industry grows a lot, oil through pipeline transportation, fluid products such as chemical industry increase day by day, because the dispute of manually taking to manage transfusion fluid sample problem typical gets more and more, especially oil, chemical industry, the commodity transaction amount of fluid product is big, its sample representation problem directly influences both sides' economic benefit, and the sampling mode that adopts at present, only be to get a not good liquor sample as quantitative target by artificial per 1～2 hour, because of artificial factor, its accuracy is low, and reliability is difficult to guarantee, can not adapts to the needs of marketing transaction far away.
The purpose of this utility model provides the on-line automatic sampler of liquid line that interference from human factor was taken a sample, was not subjected to a kind of adjustable clearance automatically.
The on-line automatic sampler of the utility model liquid line, it comprises Hydraulic Station, automatic control system, solenoid valve, the hydraulic jack of one usefulness solenoid control is set, its cylinder body inner carrier links to each other with plunger by connecting rod, plunger is located in the sample oil cavity that links to each other with oil cylinder, the connection place of two cavitys is provided with sliding sleeve up and down, the top of sample oil cavity is provided with discharging tube, and its end is provided with end cap, and end cap is provided with pipette and stopple coupon, pipette and stopple coupon are communicated with the endoporus of end cap, and the stopple coupon exit is provided with sampling jar.
The on-line automatic sampler of the utility model liquid line, adopt the to-and-fro movement of piston in piston/cylinder, driving plunger extracts the fluid sample in the fluid-carrying lines to the sample oil pocket, pipette links to each other with Trunk Line with discharging tube, be equipped with retaining valve in the inlet of pipette and discharging tube, also be provided with retaining valve in the inlet of stopple coupon.The connection port place of the sliding sleeve that is provided with of two cavity connection places and be equipped with O-ring seal with the piston rod cooperation place is equipped with O-ring seal on oil cylinder piston and the plunger up and down.
The on-line automatic sampler of the utility model pipeline, be best suited for the pipeline transportation liquid sampling of oil, chemical industry, the hydraulic jack of one solenoid control is set, oil cylinder piston and the plunger interlock that is located in the sample liquid cavity, the sample liquid cavity is communicated with stopple coupon, by plunger fluid sample is sucked in the sample sap cavity, be characterized in: sampling amount is not stressed and Temperature Influence, and the sample of taking-up has promptness, true representative; Its, adjustable gaps can be provided with automatic sampling off time according to the size of flow (frequency) sample time; Sample tap is Height Adjustable, simple installation; When motor is out of service, can report to the police automatically, solved the representative not enough problem of fluid-carrying lines hand sampling, overcome human factor, made the sample of obtaining have more representativeness and fairness, carry liquid particularly outstanding to heterogeneity, instability, have practicality widely.
Description of drawings:
Accompanying drawing is a structure cut-open view of the present utility model.
Below in conjunction with accompanying drawing an embodiment of the present utility model is described further:
The on-line automatic sampler of the utility model liquid line, it includes Hydraulic Station, automatic control system, solenoid valve 12, hydraulic jack 9 with solenoid valve 12 controls is set, its cylinder body inner carrier 10 links to each other with plunger 6 by connecting rod, plunger 6 be located at the sample oil cavity 7 that links to each other with oil cylinder 9 in, by plunger 6 to-and-fro movement in cylinder body 7, to extract the fluid sample of larger volume in cylinder body 7 in the fluid-carrying lines and through sampling line, and then the overwhelming majority of fluid sample in the cylinder body is sent again back to the downstream of delivery line by plunger 6 from vent pipe 11, only stay 1～10ml fluid sample to send in the sampling jar 5 from stopple coupon 4, height according to the size control sample tap of getting liquid sample amount, the top of sample oil pocket 7 is connected with discharging tube 11, its end is provided with end cap 2, and the pipette 1 that is provided with in the via top that is provided with on the end cap 2 and the side opening is communicated with, in the middle part of the through hole and be connected the side opening connection of stopple coupon 4.Pipette 1 links to each other with Trunk Line with discharging tube 11, is provided with retaining valve 3,13 in the inlet of pipette 1 and discharging tube 11.Sliding sleeve 8 is located at the up and down connection place of two cavitys, the connection port place of sliding sleeve 8 and be equipped with O-ring seal with the piston rod cooperation place.When the Hydraulic Station running hours, 12 energisings of automatic controlling system solenoid valve, hydraulic jack 9 work, hydraulic oil promotes piston 10 and down moves, plunger 6 moves with son, suction flows into the potpourri in the Trunk Line from pipette 1, opening retaining valve 3 enters in the sample chamber 7, until potpourri (as crude oil) sample chamber 7 is filled, solenoid valve 12 cuts off the power supply automatically, and hydraulic oil oppositely promotes upwards operation of piston 10 at once, the fluid sample that plunger 6 promotes in the sample chamber 7 is past return, retaining valve 3 is closed at once, and this moment, vent pipe 11 internal check valves 13 were opened, and most liquid flow back to the Trunk Line downstream from vent pipe 11 in the sample chamber 7.When plunger 6 moved to exhaust opening and the hole shut, Hydraulic Station pressure increased the retaining valve of opening in the stopple coupon 4 14, and remaining fluid sample flows in the sampling jar 5, and when piston 10 was got back to the origin-location, this inferior volume sample sampling finished.Hydraulic Station can be continuously or the gap operation, and the gap sample time and the T.T. of actual requirement can be set, and then can obtain sample total amount accurately.
