Abstract
The utility model discloses a kind of filter cleaner leak locator, comprise tested filter cleaner, source of the gas and pressure transducer, described tested filter cleaner is placed in back up pad, seal closure is located in the back up pad outside tested filter cleaner, cushion is provided with between described seal closure lower end and back up pad, be provided with between end face under described tested filter cleaner and described seal closure and play shape part, first pressure transducer is communicated with tested filter cleaner, second pressure transducer and the cavity connects between seal closure and tested filter cleaner, gas circuit between seal closure and source of the gas is arranged the second valve, gas circuit between cylinder and source of the gas is arranged the first valve, the piston rod of described cylinder is relative with the end face of seal closure.The utility model has the remarkable advantage that test is accurate, test efficiency is high and can not cause quality influence to filter cleaner.
Description
Technical field:
The utility model relates to a kind of measuring technique, particularly a kind of filter cleaner leak locator.
Background technology:
Whether existing filter cleaner leak locator is that filter cleaner is placed in water, to the gas being filled with certain pressure in filter cleaner, keeps certain hour, have bubble to produce judge that whether filter cleaner impermeability is qualified by liquid level.There is following defect in this detection method: 1. needs to dry up filter cleaner, and the part surface drying up rear filter cleaner can leave water stain, can produce certain influence to subsequent handling, thus the quality of the clear device of contributive rate; 2. filter cleaner is when being immersed in the water, if misoperation can make filter cleaner pollute, causes shorten serviceable life; Filter cleaner needs artificial loading in frock, and lost time is many, and efficiency is low.
Summary of the invention:
The utility model object is to provide a kind of test accurately, and test efficiency is high and filter cleaner is not caused to a kind of filter cleaner leak locator of quality influence.
Realizing the utility model object technical scheme is, a kind of filter cleaner leak locator, comprise tested filter cleaner, source of the gas and pressure transducer, it is characterized in that: described tested filter cleaner is placed in back up pad, seal closure is located in the back up pad outside tested filter cleaner, cushion is provided with between described seal closure lower end and back up pad, be provided with between end face under described tested filter cleaner and described seal closure and play shape part, first pressure transducer is communicated with tested filter cleaner, second pressure transducer and the cavity connects between seal closure and tested filter cleaner, gas circuit between seal closure and source of the gas is arranged the second valve, gas circuit between cylinder and source of the gas is arranged the first valve, the piston rod of described cylinder is relative with the end face of seal closure.Elastic component between described tested filter cleaner and seal closure is spring or rubber blanket.
The utility model has the remarkable advantage that test is accurate, test efficiency is high and can not cause quality influence to filter cleaner compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment:
The utility model has following embodiment, tested filter cleaner 8 is placed in back up pad 1, seal closure 3 is placed in described back up pad, tested filter cleaner is covered, O-ring seal 2 is provided with between the lower surface of described seal closure and back up pad, spring 10 is located between tested filter cleaner top and seal closure, and a pressure transducer 9 is placed in the below of back up pad and tested filter cleaner cavity connects, and another pressure transducer 4 is placed on seal closure and cavity connects between seal closure and tested filter cleaner.To the cavity insufflation gas between seal closure and tested filter cleaner or bleed to above-mentioned cavity, make the air pressure in tested filter cleaner (atmospheric pressure) not identical with the gaseous tension of cavity between seal closure and tested filter cleaner, keep certain hour, by doing to judge to the numerical value change of above-mentioned two pressure transducers: when the force value in tested filter cleaner is constant, tested filter cleaner is qualified; The pressure difference of the air pressure of the force value in seal closure cavity and tested filter cleaner is larger, judges that the time of two pressure transducer numerical value change is shorter, generally only needs several 10 seconds.
As an embodiment, downward pressure is applied to seal closure and tested filter cleaner, cylinder 5 can be adopted to apply pressure, also manually can apply pressure, because the pressing time needed is shorter; If source of the gas, at source of the gas and arrange gas circuit respectively between seal closure and cylinder and arrange the first valve and the second valve respectively in gas circuit.Wherein the first valve 6 is located in the gas circuit between source of the gas and cylinder, and the second valve 7 is located in the gas circuit between source of the gas and seal closure.Spring 10 or rubber blanket are set between tested filter cleaner and seal closure, the height of spring or rubber blanket should meet following requirement, when seal closure is placed on tested filter cleaner, the lower surface of seal closure does not contact with back up pad, when namely downward pressure being applied to seal closure, first, after making tested filter cleaner and back up pad seal, seal closure continues to move down makes seal closure and back up pad seal.
Method of operating, first tested filter cleaner is placed in back up pad, then seal closure is placed on the spring (or rubber) of tested filter cleaner top cover, open the first valve, cylinder applies pressure to seal closure, after tested filter cleaner and back up pad, seal closure and back up pad seal, close the first valve, cylinder stops action; Open the second valve to inflate seal closure internal cavity, when its air pressure reaches setting value, close the second valve, stop inflation, the first pressure transducer keeping this pressure to observe in setting-up time being communicated with tested filter cleaner and and the force value of the second pressure transducer of cavity connects between seal closure and tested filter cleaner whether change, just can judge that whether tested filter cleaner qualified.
Claims (2)
1. a filter cleaner leak locator, comprise tested filter cleaner, source of the gas and pressure transducer, it is characterized in that: described tested filter cleaner is placed in back up pad, seal closure is located in the back up pad outside tested filter cleaner, cushion is provided with between described seal closure lower end and back up pad, be provided with between end face under described tested filter cleaner and described seal closure and play shape part, first pressure transducer is communicated with tested filter cleaner, second pressure transducer and the cavity connects between seal closure and tested filter cleaner, gas circuit between seal closure and source of the gas is arranged the second valve, gas circuit between cylinder and source of the gas is arranged the first valve, the piston rod of described cylinder is relative with the end face of seal closure.
2. a kind of filter cleaner leak locator according to claim 1, is characterized in that: the elastic component between described tested filter cleaner and seal closure is spring or rubber blanket.
