Abstract

The utility model relates to a cutting sleeve type pipe joint used in a pipe passage system for oil, gas and general corrosive media. The pipe joint comprises a cutting sleeve, a cap nut and a joint body, wherein a sealing ring is arranged on the inner conical surface of the joint body (1) connected with the cap nut by screws, and a baffle ring covering the cutting sleeve is arranged on one end of the joint body near the sealing ring. The utility model has the characteristics of reliable sealing performance, vibration resistance, fluid pressure impact resistance and convenient maintenance, and is suitable for connecting guide pipes for conveying caustic fluid and joint bodies even under the conditions of high pressure or low pressure or negative pressure.

Description

Bite type fittings with the rubber seal sealing
The utility model relates to a kind of Bite type fittings, especially for the Bite type fittings of the pipe-line system of oil, gas and general corrosion medium.
Conduit in the known technology and fittings body FERRULETYPE interconnection technique all are to make by existing standard GB 3733.1-83~GB3764-83, his main structure is made up of cutting ferrule, cap nut and fittings body, the deficiency of this structure is that this pipe joint compresses with metal ferrule and 24 ° of conical surfaces of fittings body, easily cause the fittings body conical surface to damage, escape of liquid takes place, when next is the pipe joint assembling, the screw-down torque of cutting ferrule nut is difficult to control, screw-down torque is too small, then sealing surface compact power is not enough, easily leaks; Screw-down torque is excessive, can cause cutting ferrule to damage.Secondly be pipe joint again before formal assembling, need special-purpose pipe joint preloader,, will the conduit joint after the assembling be leaked in case preassembly is improper to the conduit preassembly of going ahead of the rest.Therefore the technical merit to workman's assembling has higher requirements.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of anti-shaking is provided, the Bite type fittings with the rubber seal sealing of fluid-resistant compression shock.
The utility model is the further improvement to existing conduit and fittings body FERRULETYPE interconnection technique.
Technical solution of the present utility model is to comprise a cutting ferrule (5), cap nut (6) and fittings body (1), its special way is to be bolted in the conical surface of fittings body (1) of cap nut seal ring (3) is housed, and is pressed in shelves rings (4) on the cutting ferrule (5) in that a lid also is housed by seal ring (3) and fittings body (1) one end.
The utility model seal ring can be that the cross section is the wedge type rubber seal, also can be the seal ring of ladder type or O type shape.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model Bite type fittings structure half sectional view.
Fig. 1 shows a kind of embodiment of the utility model.This Bite type fittings is mainly by fittings body (1), rubber seal (3), and cutting ferrule (5), shelves rings (4), cap nut combines.Wherein cap nut (6) and fittings body (1) can be continued to use existing NBS.Tighten cap nut (6) during assembling, make cutting ferrule (5) outer cylinder be deformed into arc, make it to be close to, form sealing surface with the inner conical surface of shelves rings (4).Being connected of cutting ferrule and conduit realized in cutting ferrule (5) location automatically when shelves ring (4) not only can guarantee to assemble, and can also make the anterior cutting edge of cutting ferrule (5) along shelves ring inner conical surface incision conduit (2) outer wall, can also stop moving of rubber seal simultaneously, guarantees to seal.And the effect of cap nut (6) is cutting ferrule (5), and shelves rings (4) and fittings body (1) link together, and realizes that conduit is connected with fittings body, makes the joint realize sealing.
Fittings body of the present utility model (1) can be made by the different requirements in GB3734.1~3758.1, can be straight-through, threeway, articulated joint, dividing plate joint etc.
The utility model compared with prior art has following advantage and good effect:
1, owing to adopted the press seal of 24 ° of inner conical surfaces of rubber seal and fittings body, can not decrease The conical surface of bad fittings body and generation fluid leakage.
2, the use of shelves ring, the automatic location of cutting ferrule when having guaranteed assembling. Fluid pressure in conduit has Rubber seal pushed away the fittings body conical surface and when causing the trend of leakage, the shelves ring can stop rubber seal Move and guarantee to seal. The assembly crewman is when tightening cap nut, because shelves ring drag effect causes moment prominent The feel that increases is just known to be seated.
3, the utility model does not need special-purpose pipe joint preloader, does not need pipe joint with conduit yet Pre-assembled.
4, owing to the reliability of sealing rubber ring and shelves ring, feasible conduit to same specification connects sealing load raising, anti-shaking, fluid-resistant compression shock.
5, easy to maintenance, expense descends.Use or repeatedly install and remove conduit and may cause the joint to be leaked long-term, prior art not only Cost of repair and maintenance is bigger, but also will change joint, conduit and cutting ferrule.And the utility model only need be changed rubber seal and can get rid of leakage.
The utility model is applicable under high low pressure or the subnormal ambient, even has the conduit of corrosive fluid conveying and being connected of fittings body.

Claims (2)

1, a kind of Bite type fittings, Bite type fittings especially for the pipe-line system of oil, gas and general corrosion medium, comprise a cutting ferrule (5), cap nut (6) and fittings body (1), it is characterized in that: be bolted in the conical surface of fittings body (1) of cap nut (6) seal ring (3) is housed, at a end lid is housed also and is pressed on shelves rings (5) on the cutting ferrule (5) by seal ring (3) and fittings body.
2, connect the described pipe joint of claim 1, it is characterized in that seal ring (3) is the wedge type rubber seal for the cross section.
