Abstract
The invention discloses a gasometern sealing performance detection device having a dual-linked air clamper. The device comprises a detection unit and a dual-linked air clamper and is characterized in that dual-linked air clamper is provided with two fixed semi-circular nuts for supporting two air pipes by air pipe threaded segments; two movable semi-circular nuts moving up and down are arranged above openings of the two fixed semi-circular nuts; and the two movable semi-circular nuts are connected by a connecting plate pushed by a cylinder. The fixed semi-circular nuts and the movable semi-circular nuts are in a screw-thread fit relation to form clamping of the air pipe threaded segments. Preferably, the connecting plate is hinged to a far end of a piston rod of the cylinder; and a guiding structure guided by a guiding post is formed between the fixed semi-circular nuts and the movable semi-circular nuts. The device has the following beneficial effects: the structure is simple; the clamping become reliable; and damages on the air pipe thread can be avoided.
Description
Technical field
Patent of the present invention relates to a kind of gas meter sealing detection equipment, particularly a kind of gas meter leak-testing apparatus with duplex air clamper.
Background technology
Gas meter is the instrument for measuring gas consumption, and metering movement is arranged in watchcase, and gas meter is connected with source of the gas and gas equipment end with escape pipe respectively by draft tube.The type of attachment of the tracheae of existing domestic gas meter is arranged to be threaded usually, and therefore, the tracheae of gas meter has external thread structure, to be connected with source of the gas and gas equipment end pipeline respectively.The sealing of gas meter watchcase not only directly affects metering accuracy, and prior relating to uses gas safety.For this reason, need to carry out sealing propertytest before gas meter dispatches from the factory.Checkout equipment comprises detecting unit and gas meter positioning clamping device, and detecting unit is used for, by after the turnover tracheae shutoff of gas meter sealing, inflating in watchcase, the leakage rate of test watchcase in setting-up time or Pressure Drop.Existing detecting unit technical perfection, can realize automatic plugging easily, inflate and the warning that exceeds standard.But because gas meter watchcase is thin-wall case structure, detect fixing can only selection on tracheae.Existing installation way is, gas-pipe thread section is set with nut, carries out watchcase and fixes by straining or compress the axially displaced mode of this nut restriction nut, to resist the thrust that sealing detection end socket his-and-hers watches hull shape becomes.Its clamping non-productive operation is loaded down with trivial details, and easily causes gas-pipe thread to pull, particularly when two nuts screw togather position front-back staggered, particularly outstanding because axial limiting bearing distribution is uneven.For this reason, require further improvement.
Summary of the invention
Object of the present invention is exactly for the deficiencies in the prior art, provides that a kind of structure is simple, reliable clamping, and not easily gas-pipe thread is formed to the gas meter leak-testing apparatus with duplex air clamper of injury.
For achieving the above object, the present invention adopts following technical scheme.
A kind of gas meter leak-testing apparatus with duplex air clamper, comprise detecting unit and duplex air clamper, it is characterized in that, described duplex air clamper is provided with and is respectively used to support two of two tracheaes by gas-pipe thread section and fixes half round nut, two overthe openings fixing half round nut are respectively equipped with two only movable half round nuts moving up and down, two movable half round nuts are connected by the web joint of cylinder-pushed by one, fix half round nut and movable half round nut for being formed the clamping to gas-pipe thread section by threaded engagement.
Adopt the present invention of preceding solution, gas meter watchcase is fastened by two semicircle nut clip of threaded engagement in gas-pipe thread section, and the synchronous clamping realizing two tracheaes by cylinder and web joint is fixed, its clamping is firmly leaned on, thus when can effectively reduce or avoid compression or sealing propertytest, to the damage of gas-pipe thread.
Preferably, the piston rod distal end articulated of described web joint and cylinder.To form uniform pressure distribution on two activity half round nuts, avoid weighing the screw thread on watchcase tracheae wounded.
Preferably, describedly the guide frame being formed through guidepost between half round nut and movable half round nut and leading is fixed.Cause screw thread on tracheae to be weighed wounded to avoid traveling nut to misplace, and compress reliable.
Preferably, described movable half round nut is made up of aluminium alloy or aldary.With hardness lower than the turnover tracheae hardness be made up of structural steel, guarantee further and weigh gas-pipe thread wounded.
The invention has the beneficial effects as follows, structure is simple, reliable clamping, and not easily injury is formed to gas-pipe thread.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated, but therefore do not limit the present invention among described scope of embodiments.
See Fig. 1, a kind of gas meter leak-testing apparatus with duplex air clamper, comprise and be respectively used to support two of two tracheaes by gas-pipe thread section and fix half round nut 1, two overthe openings fixing half round nut 1 are respectively equipped with only activity half round nut 2 be made up of aldary or aluminium alloy moving up and down, two movable half round nuts 2 are connected by a web joint promoted by cylinder 34, fix half round nut 1 and movable half round nut 2 for being formed the clamping to gas-pipe thread section by threaded engagement.The piston rod 3a distal end articulated of web joint 4 and cylinder 3; Each fixing on half round nut 1 is fixed with a guidepost 5, and movable half round nut 2 is provided with the pilot hole 2a with this guidepost 5 clearance fit, to make to fix the guide frame being formed through guidepost 5 between half round nut 1 and movable half round nut 2 and leading.
Guidepost 5 in the present embodiment also can fixedly be located on movable half round nut 2, and corresponding half round nut 1 of fixing is provided with the pilot hole with this guidepost 5 clearance fit.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
