Description
Technical field
The utility model relates to domestic gas meter movement leak detection technology, is related specifically to a kind of domestic gas meter movement leak detecting device.
Background technology
Domestic gas meter movement, in manufacturing process, needs and manufacturing procedure that kind more longer through process, therefore, all requires to carry out leak detection one by one after machining, to prevent from, because manufacturing deficiency causes gas leakage, eliminating safe hidden trouble.Whether prior art domestic gas meter movement leakage detection method adopts filling gases at high pressure in gas meter movement, then places it in pond, observe and have bubble to occur, confirms whether gas meter movement exists leakage successively.Owing to will the gas meter movement of filling gases at high pressure is placed in pond, therefore, need to carry out shutoff to the air inlet/outlet of gas meter movement after filling gases at high pressure, operate very numerous and diverse, and the gas meter movement that easy damage has processed.In addition, being placed in pond by the gas meter movement of filling gases at high pressure is also the operation of comparatively difficulty, because it has larger buoyancy, needs specific device to place.Further, be placed on after in pond, the observation of the bubble caused due to put procedure and artificial naked eyes, likely causes erroneous judgement.Obviously, prior art domestic gas meter movement leakage detection method also exists trivial operations, places the problem such as difficulty and easy erroneous judgement.
Summary of the invention
For solving the problem such as trivial operations, the difficult and easy erroneous judgement of placement that prior art domestic gas meter movement leakage detection method exists, the utility model proposes a kind of domestic gas meter movement leak detecting device.The utility model domestic gas meter movement leak detecting device, comprises frame, shutoff inflation mechanism and pressure detecting instrument; Described frame comprises the base plate and the framework that forms of upper plate that are supported by four root posts, and the heart is provided with the shape chamber of fixing gas meter movement in the soleplate, matches bottom the shape in described shape chamber and size and gas meter movement; Shutoff inflation mechanism comprises block head, slide plate and shutoff cylinder, and sliding plate sleeve is contained on four root posts, and be provided with two block heads below slide plate, connect shutoff cylinder axis above, shutoff cylinder is arranged on upper plate upper surface; Two block heads are tubular structure, and the air inlet/outlet of its distributing position and size and gas meter movement matches, and wherein, one is connected with high-pressure air source, and another is connected with high sensitivity gas pressure sensor; High sensitivity gas pressure sensor is connected with pressure detecting instrument.
The Advantageous Effects of the utility model domestic gas meter movement leak detecting device can leak gas meter movement when semi-automation to detect, instrument is adopted to judge leak case, reduce numerous and diverse degree and the degree of difficulty of operation, improve Detection job.Further, structure is simple, and cost is lower.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model domestic gas meter movement leak detecting device.
Below in conjunction with the drawings and specific embodiments, the utility model domestic gas meter movement leak detecting device is further described.
Embodiment
Accompanying drawing 1 is the structural representation of the utility model domestic gas meter movement leak detecting device, and in figure, 11 is shape chamber, and 12 is base plate, and 13 is column, and 14 is upper plate, and 21 is block head, and 22 is slide plate, and 23 is shutoff cylinder, and 3 is pressure detecting instrument.As seen from the figure, the utility model domestic gas meter movement leak detecting device, comprises frame, shutoff inflation mechanism and pressure detecting instrument 3; Described frame comprises the base plate 12 and the framework that forms of upper plate 13 that to be supported 13 by four root posts, is provided with the shape chamber 11 of fixing gas meter movement at base plate 12 center, matches bottom the shape in described shape chamber 11 and size and gas meter movement; Shutoff inflation mechanism comprises block head 21, slide plate 22 and shutoff cylinder 23, and slide plate 22 is sleeved on four root posts 13, is provided with two block heads 21, connects shutoff cylinder axis above below slide plate 11, and shutoff cylinder 23 is arranged on upper plate 14 upper surface; Two block heads 21 are tubular structure, and the air inlet/outlet of its distributing position and size and gas meter movement matches, and wherein, one is connected with high-pressure air source, and another is connected with high sensitivity gas pressure sensor; High sensitivity gas pressure sensor is connected with pressure detecting instrument 3.When specifically detecting, be placed on bottom gas meter movement to be detected in shape chamber.Owing to matching bottom the shape in shape chamber and size and gas meter movement, therefore, the placement that gas meter movement can be firm, open shutoff cylinder, slide plate moves down under the promotion of shutoff cylinder axis, until block head is by the shutoff of gas meter movement air inlet/outlet.Because the distributing position of block head and the air inlet/outlet of size and gas meter movement match, therefore, block head can effectively by the shutoff of gas meter movement air inlet/outlet, and open gas source switch, gases at high pressure are entered in gas meter movement by block head.After arriving set pressure, pressurize setting-up time.Because one of them block head is connected with high sensitivity pressure transducer, high sensitivity pressure transducer is connected with pressure detecting instrument again, therefore, can be observed the change of pressure in gas meter movement by pressure detecting instrument.When the pressure set and time, the pressure change in gas meter movement at setting range, then can be considered as this gas meter movement Leak Detection qualified, otherwise, be considered as defective.When adopting the utility model domestic gas meter movement leak detecting device to carry out Leak Detection to gas meter movement, only gas meter movement need be placed in shape chamber, or take out from shape chamber, other just Switching Power Supply, is essentially semiautomation operation.Further, adopt pressure detecting instrument to detect gas pressure change, effectively reduce numerous and diverse degree and the degree of difficulty of operation, improve Detection job.
Obviously, the Advantageous Effects of the utility model domestic gas meter movement leak detecting device can leak gas meter movement when semi-automation to detect, adopt instrument to judge leak case, reduce numerous and diverse degree and the degree of difficulty of operation, improve Detection job.Further, structure is simple, and cost is lower.
