Description
Technical field
The utility model relates to a kind of valving, particularly relates to a kind of air valve.
Background technology
At present, in the pipe production process, raw materials for production are generally without cleaning, thereby may there be impurity in products material in process of production, pipeline after moulding may exist gap and pore, so, after production obtains pipeline, all can carry out seal for pipe joints and test to detect whether on pipeline, whether have gap and pore to weigh duct products qualified.
At present, the sealing of detection pipeline is mainly to adopt pneumatic test method and water seal method of inspection.Adopting the water seal method of inspection is to water filling in pipeline, observes variation in water pressure, if hydraulic pressure changes, the pipeline blow-by is described, if hydraulic pressure does not change, illustrates that seal for pipe joints is better, is considered as specification product.But, when hydraulic pressure is larger, the thinner pipeline for some tube walls, tube wall is easily risen brokenly, and causes being detected.And the method for hydraulic test also can't the checking circuit pipeline.
So, in the situation that plurality is to adopt another kind of pneumatic test method, whether two sections sealings after pipe production, inject air pressure in pipeline afterwards again, observe the pipeline internal gas pressure and change, thereby whether appraise and decide pipeline qualified.But the method can only once be checked, can't repeatedly check, be because in conventional pipe production, by the both ends sealing, then toward the interior injecting gas of pipeline, reach certain air pressure after pipe production.In the time of check, in pipe ends, punch, then the air pressure in measuring channel.After measurement, the gas in tubing is released, and the air pressure in pipeline is identical with external pressure, so adopt the pneumatic test method to detect once.
But, when tubing is installed, after installation, or after the pipe interior cabling, because the sealing of pipe ends is opened, thus can not the sealing of pipeline be detected, unless reseal pipe ends, then detected toward pouring air pressure in pipeline.So, adopting this method, testing cost is high, and difficulty of construction is large, if detected in installation process, also can stop over the duration, increases workmen's labour intensity.
So, need badly at present a kind of can be after production completes or in installation process or install after the device that repeatedly the pipeline impermeability detected.
The utility model content
The purpose of this utility model is: exist and be difficult to the bubble-tight deficiency of repeated detection pipeline for prior art, provide a kind of the device repeatedly the pipeline impermeability detected afterwards can after production completes or in installation process or be installed.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of air valve, comprise coupling arrangement, be respectively arranged with pipeline mounting hole and air pump mounting hole on described coupling arrangement, be provided with dividing plate between described pipeline mounting hole and described air pump mounting hole, be provided with the through hole that connects described pipeline mounting hole and air pump mounting hole on described dividing plate, be provided with valve cock in described air pump mounting hole, on described valve cock, be provided with valve inside.In use, in pipe ends, air valve is set respectively, air valve is arranged on pipeline by the pipeline mounting hole, after installing, the air pump mounting hole of an air valve arranges air pump therein, air pump is pressed into gas by valve inside in pipeline, because the pipeline other end is sealed by another air valve, so the air pressure in pipeline increases, thereby can the impermeability of pipeline be detected, make it possible to after production completes or repeatedly the pipeline impermeability detected in installation process or after installing, and easy to operate, can not stop over the duration and bring onerous toil to the workmen.
As preferably, on described valve cock lateral wall, be provided with the groove matched with described dividing plate.When mounted, described dividing plate is arranged in groove, and then makes firm being arranged on coupling arrangement of valve cock.
As preferably, an end lateral wall projection of described valve cock is spherical, and described groove is arranged at the spherical position of described valve cock.Due to after the valve cock side offers groove, valve cock is being offered the position strength decreased of groove, so the position of groove will be set, raises into spherically, has increased the wall thickness at the groove position of valve cock, thus avoided valve cock due to groove being set strength decreased.
As preferably, the spherical position of described valve cock lateral wall projection and other parts of valve cock lateral wall seamlessly transit.Avoid on the valve cock lateral wall sudden change wedge angle occurring and produce stress concentrated in, also make it possible to facilitate valve cock is arranged in coupling arrangement.
As preferably, described valve inside arranged outside has sheath body, and described valve inside is arranged on described valve cock by described sheath body, and the described sheath body outside is arranged with valve cap.In transportation and use procedure, by being set, valve cap protect valve inside not by F. O. D.
As preferably, the inlet end of described valve inside is towards described pipeline mounting hole, and the outlet side of described valve inside is towards described air pump mounting hole.When carrying out the detection of pipeline impermeability, if input gas in pipeline, the pipeline internal gas pressure raises, when pipeline strength is not high enough, tube wall is easily outwards heaved outstanding, by outside other article, punctured or by the air pressure inside spalling, so by the inlet end of valve inside towards the pipeline mounting hole, while carrying out the detection of pipeline impermeability, air pump is bled outside pipeline, produce negative pressure in pipeline, whether the air pressure detected again in pipeline changes, thereby avoided pipeline owing to outwards heaving the risk be punctured, also avoided pipeline by the danger of air pressure inside spalling simultaneously.
Air valve of the present utility model, in use, in pipe ends, air valve is set respectively, air valve is arranged on pipeline by the pipeline mounting hole, after installing, the air pump mounting hole of an air valve arranges air pump therein, by air pump to by valve inside, in pipeline, being pressed into gas, because the pipeline other end is sealed by another air valve, so the air pressure in pipeline increases, thereby can the impermeability of pipeline be detected, thereby make it possible to after production completes or repeatedly the pipeline impermeability detected in installation process or after installing, and easy to operate, can not stop over the duration and bring onerous toil to the workmen, and, the outlet side of valve inside is towards the air pump mounting hole, when carrying out the detection of pipeline impermeability, if input gas in pipeline, the pipeline internal gas pressure raises, when pipeline strength is not high enough, tube wall is easily outwards heaved outstanding, by outside other article, punctured or by the air pressure inside spalling, so by the inlet end of valve inside towards the pipeline mounting hole, while carrying out the detection of pipeline impermeability, air pump is bled outside pipeline, produce negative pressure in pipeline, whether the air pressure detected again in pipeline changes, thereby avoided pipeline owing to outwards heaving the risk be punctured, also avoided pipeline by the danger of air pressure inside spalling simultaneously.
As shown from the above technical solution, the beneficial effects of the utility model are:
1, utilize this air valve to detect pipeline by the measurement to gaseous tension and whether to have in process of production gap and pore to injecting gas in pipeline, pipeline valve can repeatedly be used, and the check pipeline is repeatedly exerted pressure;
2, can be to the pipeline injecting gas after pipeline is installed, and then detect in installation process whether cause piping failure;
3, can apply negative pressure to pipeline, detect the pipeline internal gas pressure and whether change, weigh seal for pipe joints, avoid pipeline to be punctured and by the risk of air pressure inside spalling owing to outwards heaving;
4, facilitate the bubble-tight detection of pipeline;
5, simple in structure, easy to use;
