Abstract
The utility model discloses a leakage detecting device for a hydraulic valve. The bottom of the pipeline of the hydraulic valve (1) is provided with a leakage detecting hole (2) on which a nut (3) is welded. The nut (3) is provided with a bolt (4) for sealing. The leakage detecting hole (2) is sealed through the nut (3) and the bolt (4). In leakage detection, the bolt is opened, and water is added from the upper part of the hydraulic valve. If water current exists, inner leakage of the valve exists; and if no water current occurs, no leakage of the valve exists. The leakage condition of the valve can be checked conveniently, thereby effectively preventing error determination for leakage condition of the valve. Through small reconstruction of the hydraulic valve, a big problem in chemical production is settled. Time of the enterprise is saved. Furthermore the leakage detecting device for the hydraulic valve has high practical value.
Description
Technical field
The utility model relates to valve leak hunting technology field, particularly relates to a kind of hydraulic valve leakage detection apparatus.
Background technology
At present, in the prior art, when hydraulic valve is hunted leak, often whether the operator has weeping to carry out observe and decide according to the experience of oneself to the appearance of hydraulic valve, and this method often there will be the erroneous judgement of valves leakage disconnected.The leak hunting method of this hydraulic valve of the prior art not only affects actual application, also time-consuming, and increases again workman's labour intensity.Therefore, the leak detection mode of existing hydraulic valve is still very undesirable.
Summary of the invention
Technical problem to be solved in the utility model is to overcome existing hydraulic valve the defect of erroneous judgement often to occur when leak detection, a kind of leak hunting method and device thereof of hydraulic valve are provided, simple, be convenient to the interior leakage situation of check valve, the erroneous judgement to the valves leakage situation in the time of can effectively avoiding overhauling is disconnected.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The leakage detection apparatus of a kind of hydraulic valve of the present utility model is: the duct bottom at hydraulic valve has leak hunting aperture, is welded with the nut adapted with its size at the leak hunting aperture place, and the bolt for sealing is housed on nut, and leak hunting aperture seals by nuts and bolt.
Above-mentioned hydraulic valve is water-sealed valve.
While in check valve, leaking situation, first open bolt, and then pour water in hydraulic valve, if there are flowing out the proof valves leakage, the not interior leakage of valve if non-water flow is issued a certificate.
Compared with prior art, the utility model method is simple, the apparatus structure provided is simple, the interior leakage situation of check valve easily, erroneous judgement to the valves leakage situation while effectively avoiding overhauling is disconnected, hydraulic valve has solved the large problem of Chemical Manufacture through slight transformation, for enterprise has won the time, have extraordinary practical value.The utility model is particularly suitable in factory three gas water-sealed valves leak detections commonly used and uses (being the water-sealed valve that pressurized air, rock gas, gas piping are used).
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the structural representation of the leakage detection apparatus of a kind of hydraulic valve of the present utility model as shown in Figure 1, during making, open a leak hunting aperture 2 in the duct bottom of hydraulic valve 1, at a nut 3 adapted with its size of leak hunting aperture 2 place's welding, leak hunting aperture 2 is by nut 3 and bolt 4 sealings.The water-sealed valve that its hydraulic valve 1 preferably uses on three feed channel of the prior art.
When leak detection, first open bolt, and then pour water in hydraulic valve, if there are flowing out the proof valves leakage, the not interior leakage of valve if non-water flow is issued a certificate.The method is convenient and swift and can avoid the erroneous judgement to the valves leakage situation.
Claims (2)
1. the leakage detection apparatus of a hydraulic valve, it is characterized in that: the duct bottom at hydraulic valve (1) has leak hunting aperture (2), locate to be welded with nut (3) at leak hunting aperture (2), bolt (4) for sealing is housed on nut (3), and leak hunting aperture (2) is by nut (3) and bolt (4) sealing.
2. the leakage detection apparatus of hydraulic valve according to claim 1, it is characterized in that: described hydraulic valve (1) is water-sealed valve.
