Abstract
This utility model relates to the attachment means in a kind of antiknock device, and particularly to a kind of explosive-proof sealed articulation, this sealed explosion-proof articulation includes water proof ring, fittings body, explosion-proof sealing ring, clamp nut, pressed joint.This utility model explosion-proof sealing ring is taper, and utilizes displacement extrusion principle, solves the problems such as equipment sealing effectiveness is bad, explosion-proof sealing ring extruding is fragile, installation is inconvenient.This utility model is the most cost-effective, it is provided that installment work efficiency.
Description
Technical field
This utility model relates to the attachment means in antiknock device, particularly to a kind of explosive-proof sealed articulation.
Background technology
In chemical industry, space flight, gas-recovery station, place, ore deposit factory high-risk place, the cable connector junction of various antiknock devices needs explosive-proof sealed articulation.Often expose to the weather in place used by explosive-proof sealed articulation, bad environments, therefore the explosion-proof performance of the explosive-proof sealed articulation of antiknock device joint is required high, once Explosion proof joint goes wrong, the operation of antiknock device will be had a strong impact on, even the lives and properties of people are brought extreme loss, it is therefore desirable to the anti-explosion movable joint that a kind of explosion-proof effect is excellent, easy for installation.
Therefore, in order to solve above technical problem, design a kind of explosive-proof sealed articulation, EX PACKING GLAND is by water proof ring as shown in Figure 1, fittings body, explosion-proof sealing ring, clamp nut, pressed joint forms, water proof ring is put at fittings body left end external screw thread, and it connects with the equipment place of company, and formation is firm to be connected, so fittings body right-hand member female thread connects clamp nut female thread, and clamp nut inner chamber is equipped with explosion-proof sealing ring, pressed joint left end bayonet socket is in clamp nut inner chamber, pressed joint right-hand member female thread connects antiknock device junction, dextrorotation tight coupling body, explosion-proof sealing ring is made to be subjected to displacement, taper into internal diameter of the seal ring, finally it is fastened on cable outer wall, fully seal the space between the external world and spool, thus realize the purpose of sealed explosion-proof.And the explosion-proof sealing ring of described explosive-proof sealed articulation is taper, such Screw joint body makes explosion-proof sealing ring stress evenly, plays the effect of protection explosion-proof sealing ring, the biggest potential safety hazard reducing Code in Hazardous Special Locations.
Utility model content
In order to overcome defect present in background technology, this utility model solves its technical problem and be the technical scheme is that a kind of explosive-proof sealed articulation, including water proof ring, fittings body, explosion-proof sealing ring, clamp nut, pressed joint, fittings body left end puts water proof ring and connects equipment junction, fittings body right-hand member connects clamp nut, clamp nut intracavity has explosion-proof sealing ring, pressed joint left end is snapped in clamp nut inner chamber, pressed joint right-hand member connects equipment, dextrorotation tight coupling body, it is that explosion-proof sealing ring is subjected to displacement, its internal diameter is made to taper into, finally it is locked on cable, reach sealed explosion-proof effect.
The beneficial effects of the utility model are: sealed explosion-proof excellent effect, convenient install, cost-effective.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the sectional view of a kind of explosive-proof sealed articulation of this utility model.
Wherein: 1, water proof ring；2, fittings body；3, explosion-proof sealing ring；4, clamp nut；5, pressed joint.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.Accompanying drawing is the schematic diagram simplified, and basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
Being embodied as one, refer to Fig. 1, a kind of explosive-proof sealed articulation, including water proof ring 1, fittings body 2, explosion-proof sealing ring 3, clamp nut 4, pressed joint 5.Described, water proof ring on fittings body 2 left end inner screw sheath, and connect the junction of antiknock device, fittings body 2 right-hand member external screw thread connects the female thread of clamp nut 4, the inner chamber of clamp nut 4 is equipped with explosion-proof sealing ring, the left end of pressed joint 5 is snapped in the inner chamber of clamp nut 4, the right-hand member female thread of pressed joint 5 connects the junction of equipment, dextrorotation tight coupling body 2, explosion-proof sealing ring 3 is subjected to displacement so that it is internal diameter slowly diminishes, and is finally fastened on the outer wall of cable, fully seal the space of external environment and pipeline, thus reach explosive-proof sealed effect.Described explosion-proof sealing ring 3 is taper, range of taper 25-55 degree, its diameter of bore scope 10-25 millimeter, its exit orifice diameter range 22-35 millimeter.By above-mentioned design, fittings body 2 extrudes explosion-proof sealing ring 3 and brings it about displacement, acts simultaneously on the stress on explosion-proof sealing ring 3 the most uniform, improves the life-span of explosive-proof sealed articulation, and it is easily installed with cost-effective, well solve the connectivity problem of antiknock device in high prestige place.
