Description
Technical field
The utility model relates to the detection field of various pipeline leakage, and specifically a kind of pipeline utilizes and detects the self expansion airtight fixture that medium (gas) pressure makes connection frock generation sealing.
Background technology
The joint of manufacturing enterprise to the Leak Detection connecting pipeline of axial seal mat structure of current pipeline does not have reliable scheme, main by complicated tool structure, force external force, sealing is produced after point of attachment is squeezed, there is many drawbacks like this, as: 1. product is subject to external force excessive and distortion and even inefficacy, affects product quality; 2. during Product processing because mechanism is too complicated, assembly difficulty increase, thus production efficiency is not high; 3. during Product processing, people's safe reliability is poor.
Utility model content
An object of the present utility model is to provide a kind of self expansion airtight fixture, realize utilizing and detect medium (mainly gas) pressure, promote plunger press seal pad, realize naturally sealing of point of attachment, simplify mounting means, improve process velocity, ensure product not by the impact that strong external force produces.
To achieve these goals, the technical solution of the utility model is: a kind of self expansion airtight fixture, comprise clamp, be arranged on the main body in caliper jaw, it is characterized in that the jaw front end of clamp arranges bayonet socket, tested pipeline pressing plate installing space is left between main body and bayonet socket, two plunger chamber are set in main body, described plunger chamber opening is towards tested pipeline pressing plate installing space, in described plunger chamber, plunger is set, between plunger the inner and plunger chamber, plunger spring is set, main body is stretched out in plunger outer end, plunger overcoat O type circle forms sealing, in described main body, the plunger inner space of two plunger chamber is communicated with.
Described plunger outer end arranges depressed part, and through hole is set in described plunger, described through hole extends to plunger the inner from described depressed part, tested pipeline pressing plate is provided with two mouths of pipe protruded, and one of them mouth of pipe connects draft tube, and another mouth of pipe connects escape pipe, outside described two mouths of pipe protruded, sealing gasket is set, described two mouths of pipe protruded stretch in the depressed part of plunger, and are communicated with the through hole in described plunger, and described plunger outer end contacts with the sealing gasket protruded outside the mouth of pipe.
At assembling stage, open clamp front end bayonet socket, plunger extension is inserted in pressing plate along the protrusion mouth of pipe on tested pipeline pressing plate, tested pressing plate and plunger contact, overcome the acting force of plunger spring, make plunger moves, pressing plate is pushed in clamp bayonet socket, clamp are restored closed, locked frock and pressing plate.
At airtight test phase, the gas entered from draft tube enters plunger inner space, and this pressure produces thrust to plunger base together with spring force, acts on the sealing gasket of pressing plate eventually through plunger, produce the distortion of sealing gasket, after air pressure reaches test pressure, produce the sealing at this position.
The pressure of the utility model by producing the examined gas of frock self, automatically produces and detects to pipeline the sealing needed, reach improve Product checking effect and simplify the internal structure of an organization, cost-saving object.The utility model has the advantage of and can realize automatic-sealed, improve the process velocity of product, ensure the consistance of Product checking, avoid the industrial accident in producing to occur simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is action schematic diagram of the present utility model.
Embodiment
As shown in the figure, a kind of self expansion airtight fixture, comprise clamp 6, be arranged on the main body 1 in caliper jaw, it is characterized in that the jaw end of clamp arranges bayonet socket 2, tested pipeline pressing plate installing space 3 is left between main body 1 and bayonet socket 2, two plunger chamber are set in main body 1, described plunger chamber opening is towards tested pipeline pressing plate installing space 3, plunger 4 is set in described plunger chamber, plunger 4 can move reciprocatingly in chamber, between plunger 4 the inner and plunger chamber, plunger spring 5 is set, main body 1 is stretched out in plunger 4 outer end, plunger 4 overcoat O type circle 7 forms sealing, plunger 4 inner space of interior two plunger chamber of described main body 1 is communicated with, and be connected with draft tube.
Described plunger 4 outer end arranges depressed part, and through hole 8 is set in described plunger 4, described through hole 8 extends to plunger the inner from described depressed part, tested pipeline pressing plate 9 is provided with two mouths of pipe 10 protruded, one of them mouth of pipe connects draft tube, another mouth of pipe connects escape pipe, outside described two mouths of pipe 10 protruded, sealing gasket 11 is set, described two mouths of pipe 10 protruded stretch in the depressed part of plunger, and be communicated with the through hole 8 in described plunger, described plunger 4 outer end contacts with the sealing gasket 11 protruded outside the mouth of pipe.
According to specific embodiment of the utility model, the upper end of main body 1 arranges a projection, described projection is provided with two fixed bearing pin-and-holes and two clamp spring base holes, for connection clamp 6 and clamp spring 13, described clamp comprise two calipers being arranged on main body 1 both sides, main body 1 is connected with the clamp caliper being arranged on main body 1 both sides by the pin 12 in fixed bearing pin-and-hole, and arranges clamp spring 13 between main body 1 and clamp caliper.
According to specific embodiment of the utility model, middle part and the main body 1 of described clamp are rotationally connected, and the end of clamp 8 is provided with bayonet socket 2, and for locked pipeline pressing plate, the root of clamp is then for hand-held and operate folding.
According to specific embodiment of the utility model, main body 1 inside loads plunger 4, and be lined with plunger spring 5 between plunger 4 the inner and plunger chamber, put O type circle 7, and mate with plunger chamber internal diameter outside plunger 2, form sealing, main body 1 is stretched out in plunger 4 outer end.Because plunger is in active state, outside plunger, in this design, install O type circle additional, to keep the sealing of chamber, thus made the stable of detection air pressure.
