Description
Technical field
This utility model is related to pipe fitting joint field, more particularly to a kind of Explosion proof joint.
Background technology
With the high speed development of science and technology, tech materials are more and more, more and more efficiently.At present, major part is explosion-proof connects
Head is most of using the structure being made up of sealing ring, clamp nut, metal washer and communicating joint etc..Communicating joint and casing during use
It is connected, cable is entered in casing by the endoporus of clamp nut, metal washer, sealing ring and communicating joint, the endoporus of sealing ring
With the fit clearance very little of the outside diameter of cable, sealing ring be by made by rubber, therefore when clamp nut is turned sealing ring with regard to footpath
To expansion, the purpose of sealing is reached.
For the very high product of this kind of prescription of Explosion proof joint, it is necessary to which the index of strict high specification high request is entering
Row production, could produce the expected efficiently high-quality target of high energy.Otherwise, using it is bad be exactly high destruction, easily pollute ring
The mankind will be had destructive impact by border.
The explosion-proof quality wretched insufficiency of existing Explosion proof joint, the upper existing defects of its design, sealing effectiveness be not it is ideal,
Easily cause leakage.
Therefore, we are necessary to improve such a structure, to overcome drawbacks described above.
Utility model content
The utility model proposes new type explosion proof, flame proof joint, be applied in inflammable and explosive gas or dust atmosphere, carry
A kind of Explosion proof joint for going out.
This utility model by the technical scheme that solution its technical problem is adopted is：
A kind of Explosion proof joint, including the hexagonal (hexagon)nut, copper connecting head and copper sleeve A that are sheathed on outside the double hook pipes of rustless steel,
The double pipe one end that hook of rustless steel are embedded with copper taper ring, and the pipe screw thread that hooks double with rustless steel of the copper connecting head one end on the outside of copper taper ring connects
Connect, copper connecting head other end end face is provided with some cannelures one, one inwall of cannelure is protruding with half v-seal head, copper sleeve A mono-
End end face also is provided with some cannelures two, and two inwall of cannelure is arranged with half v-seal head, and hexagonal (hexagon)nut is promoted to side precession
Copper connecting head end face and copper sleeve A end faces are brought into close contact so that two end faces compress mutually sealing.
Further, the copper taper ring side is in edge of a knife shape, and internal diameter is approximately equal to that rustless steel is double to hook pipe external diameter, copper taper ring
Opposite side is in shield mouth shape, and external diameter is more than semi-conductive adhesive bore.Used as optimization, the design of logical taper ring is strengthened to a great extent
Joint tighness.
Further, pad is additionally provided between copper connecting head end face and copper sleeve A end faces, the pad hardness connects less than copper
The hardness of joint and copper sleeve A.Used as optimization, pad can carry out moulding so that carry out integral sealing between two end faces.
Place is engaged in copper sleeve A and hexagonal (hexagon)nut, there are multiple male and female screw threads mutually to spin to form a long leptoprosopy, shape
Seal into first time.
When hexagonal (hexagon)nut and copper sleeve A screw advance so that two inclined-planes of half v-seal head and half v-seal capitiform into
Safe and reliable high-intensity sealing.
The utility model has the advantage of：
1st, design ingenious, structure is novel, reduce production cost；
2nd, hexagonal (hexagon)nut promotes copper connecting head end face and copper sleeve A end faces to be brought into close contact to side precession, substantially increases
Sealing effectiveness, does not easily cause leakage；
3rd, the design of pad can carry out moulding to end face so that two end faces form the structure of integral sealing, sealing effect
Really have and further lifted.
