Abstract
The utility model discloses a device for checking trace leakage inside a valve, in particular to a device for on-line checking of trace leakage inside the valve, which belongs to the technical field of chemical engineering pharmacy production equipment. The utility model provides the device for the on-line checking of the trace leakage inside the valve, which has the advantages that the structure is simple, and the trace leakage of the valve can be fast checked on line in time. The device for the on-line checking of the trace leakage inside the valve comprises two valves, an overflow material guide-out pipe and a detection instrument, wherein the two valves are connected on the same conveying pipeline of a production line, an input end of the overflow material guide-out pipe is communicated with the conveying pipeline arranged between the two valves, and an output end of the overflow material guide-out pipe is communicated with the detection instrument.
Description
Technical field
The utility model relates to the device of the inner micro-leakage of a kind of check valve, especially relates to a kind of device of On line inspection valve internal micro-leakage, belongs to chemical pharmaceutical production equipment technical field.
Background technology
In Chemical Manufacture, some technology or secure context do not allow valve that inner micro-leakage is arranged.The inspection method of at present general valve internal micro-leakage has following dual mode: a kind of method is the off-line inspection, promptly pulls down valve, and whether check valve inside has leakage on inspecting stand; Another kind method is onlinely to check through modes such as tensimeters.All there is deficiency in above-mentioned two kinds of inspection methods, method one exist can not On line inspection shortcoming, some valve in use owing to impurity or other reason produce valves leakage, can't effectively be checked under off-line state; Method two exist to postpone or examines owing to leakage rate is few to can not check the valve internal leakage.
The utility model content
The utility model technical matters to be solved is: provide a kind of simple in structure, and can be fast, On line inspection goes out the device of the On line inspection valve internal micro-leakage of valve micro-leakage timely.
The technical scheme that adopts for solving the problems of the technologies described above is: a kind of device of On line inspection valve internal micro-leakage; Comprise two valves that are connected on the same conveyance conduit of production line; Also comprise overcurrent material delivery line and detecting instrument; The input end of overcurrent material delivery line is communicated with conveyance conduit between two valves, and output terminal is communicated with detecting instrument.
Further be, detecting instrument is the inner cuvette that is loaded with detectable, and the output terminal of overcurrent material delivery line inserts the cuvette bottom.
The optimal way of such scheme is that detectable is water, contains the liquid of indicator, solid or check test paper.
Further be, detecting instrument is an analyser, and the output terminal of overcurrent material delivery line is communicated with analyser.
Further be on the overcurrent material delivery line between conveyance conduit and the detecting instrument, stop valve to be installed.
The beneficial effect of the utility model is: through an overcurrent material delivery line is set on the same conveyance conduit between two valves; And this overcurrent material delivery line is communicated with detecting instrument; Like this, when needs carry out the On line inspection of valve, earlier two valves on the conveyance conduit are closed simultaneously; At this moment; If the valve of input end has the micro-leakage of overcurrent material, pass through overcurrent material delivery line entering detecting instrument just the overcurrent material that then leaks can be very fast, through detecting instrument just can be convenient, fast, check out whether checked valve exists micro-leakage timely.The apparatus structure of the On line inspection valve internal micro-leakage of the utility model is simple, easy to operate, production cost is low, suits to apply widely aborning.
Description of drawings
Fig. 1 is the simplified structure synoptic diagram of the device of a kind of On line inspection valve internal of the utility model micro-leakage;
Fig. 2 is the simplified structure synoptic diagram of the device of the another kind of structure On line inspection of the utility model valve internal micro-leakage.
Be labeled as among the figure: conveyance conduit 1, valve 2, overcurrent material delivery line 3, detecting instrument 4, detectable 5, stop valve 6.
Embodiment
As Fig. 1, shown in Figure 2 be the utility model provide a kind of simple in structure, can be fast, On line inspection goes out the device of the On line inspection valve internal micro-leakage of valve micro-leakage timely.Said device comprises two valves 2 that are connected on the same conveyance conduit 1 of production line; Also comprise overcurrent material delivery line 3 and detecting instrument 4; The input end of overcurrent material delivery line 3 is communicated with conveyance conduit 1 between two valves 2, and output terminal is communicated with detecting instrument 4.Like this; When needs carry out the On line inspection of valve 2; Earlier two valves 2 on the conveyance conduit 1 are closed simultaneously, at this moment, if the valve of input end 2 has the micro-leakage of overcurrent material; The overcurrent material that then leaks just can be very fast pass through overcurrent material delivery line 3 entering detecting instruments 4, through detecting instrument 4 just can be convenient, fast, check out whether checked valve 2 exists micro-leakage timely.The apparatus structure of the On line inspection valve internal micro-leakage of the utility model is simple, easy to operate, production cost is low, suits to apply widely aborning.
According to the difference of the overcurrent material variety of carrying in the conveyance conduit 1, the detecting instrument 4 in the above-mentioned embodiment can be general analyser, also can be the cuvette that inside is loaded with detectable.When adopting the cuvette of inner splendid attire detectable; Whether be insoluble or be slightly soluble in the situation of the gas or the volatile liquid of water according to the overcurrent material; The detectable of inner splendid attire can be a water, also can be that liquid, the solid that contains indicator perhaps checked test paper.When adopting water as detectable; Can whether there be steam bubble to judge whether valve has micro-leakage through observing in the water; The liquid, the solid that contain indicator when employing are perhaps checked test paper, and whether can declare valve through the change color of liquid, solid or check test paper has micro-leakage.Because analyser needs special buying, increase that can be a large amount of detects cost, carry when checking simultaneously also very convenient, so when adopting analyser, mainly be applicable to the very serious working condition of overcurrent material from leakage harm as detecting instrument 4.
After overcurrent material delivery line 3 in the above-mentioned embodiment is provided with completion,, all be to be retained in for a long time on the conveyance conduit 1 generally for the ease of detection at any time.For the existence that makes overcurrent material delivery line 3 does not influence production, need carry out shutoff to overcurrent material delivery line 3, for the convenience of shutoff, on the overcurrent material delivery line 3 between conveyance conduit 1 and the detecting instrument 4, stop valve 6 is installed.Like this, in the time need not detecting, close stop valve 6 and just can seal overcurrent material delivery line 3 fast valve 2, easy to operate, do not influence normal production again.
When adopting the On line inspection device of the utility model to carry out online detections, have online, directly perceived, install advantages such as simple, efficient, timely, reliable, easy to implement, accuracy of judgement.
