Abstract
The utility model relates to an adapting type connecting piece, comprising a female end, a male end, a sealing ring and an elastic steel ring, wherein the inner chamber at the female end of the steel pipe is provided with an annular plow groove holding the sealing ring and an annular positioning groove holding the elastic steel ring; a plow groove for holding and connecting of the a handle grip ring is provided on the outer ring; the outer ring at the male end of the steel pipe is provided with a sealing conical surface coupled with the sealing ring, an annular boss for positioning purposes with the elastic steel ring and a flange for holding and connecting of the handle grip ring. The utility model is applicable to plastic coated steel pipes and pipeline connection engineering under inflammable and explosive conditions, with simple and convenient operations, fast connection and excellent sealing performances.
Description
The utility model relates to a kind of bayonet joint part, is specially adapted to the pipe joint of seal request strictness.
Existing pipeline connects, jointless butt welding connection commonly used, flange are connected with bolt, snap ring is connected with bolt, etc. method.The butt welding connection is inflammable as being used in, explosive environments is constructed, and regular meeting causes serious accident.For plastic-coated steel, welding can damage the coating layer of steel pipe, destroys its original corrosion resistance especially.Attended operation is slow, the not good problem of sealing and bolted other joint of every usefulness all exists.
The purpose of this utility model be for provide a kind of easy and simple to handle, connect and dismantle linkage structure rapidly.Be applicable to that the long distance laying of plastic-coated steel connects.Excellent sealing performance is arranged and lay the mobility that is connected.
For achieving the above object, the bayonet joint part that the utility model provides comprises cloudy head, sun head, the moon head and the inside and outside containing of a sun junction plane, and be furnished with seal ring 2 and flexible steel ring 3, it is characterized in that: the moon of steel pipe inner chamber has the ring-like groove of placing seal ring 2 and the annular positioning groove of placing flexible steel ring 3, has one to place the groove that connects the spanner pressure ring on the cylindrical; Sun has on the cylindrical one to be connected the flange of spanner pressure ring with a placement with the sealing cone of seal ring 2 combinations, an annular boss of locating with flexible steel ring.
Therefore, the utility model has the advantages that: easy and simple to handle when being used for the long distance line connection, connect soon good seal performance.Be suitable for plastic-coated steel and be connected construction at pipeline inflammable, explosive environments.Simultaneously, because dismounting is also convenient, also has good laying mobility.
Fig. 1 is a bayonet joint part structural representation
Below in conjunction with accompanying drawing this model utility is described further
As shown in Figure 1, this model utility is made up of cloudy 1, sun 4, seal ring 2 and flexible steel ring 3, the moon of steel pipe 51 inner chamber has the ring-like groove of placing seal ring 2 and the annular positioning groove of placing flexible steel ring 3, has one to place the groove that connects the spanner pressure ring on the cylindrical; Sun has on 4 cylindrical one to be connected the flange of spanner pressure ring with a placement with the sealing cone of seal ring 2 combinations, an annular boss of locating with flexible steel ring 3.
Adopt the yin, yang joint to peg graft on the structure, need not field welding and bolton.It contains following structural element and part: the sun 4 that has the moon 1 of an outward flange and two inner grooves and have an outward flange and an outer conical surface is welded in steel pipe 5 two ends respectively before the plastic-coated.Cloudy 1 a built-in seal ring 2 and flexible steel ring 3.
This linkage structure is connecting and use special spanner during dismounting, and only need one push away or one draw and can finish.During connection, under the thrust of spanner, sun 4 a spreading flexible steel ring 3 insert cloudy 1, and flexible steel ring 3 tightens and be positioned at cloudy 1 thereupon, between flexible steel ring 3 groove sides and sun 4 step side, realizes connecting.At this moment, the interior labial surface of seal ring 2 is attached on the conical surface of sun 4, and outer labial surface is attached on cloudy 1 the groove face, realizes sealing, and the pipe internal pressure higher it sealing effect better.In this linkage structure, having only steel pipe 5, cloudy 1, sun 4, seal ring 2 is fed sheet of a media in the contact tube, if medium has corrosivity, and steel pipe 5 harmonizing yinyang joints are postwelding plastic-coateds, only need in the then above-mentioned member to adopt corresponding resistant material (as oil resistant rubber etc.) to get final product seal ring 2.As for flexible steel ring 3, because media isolated in complete and the pipe then can not be subjected to dielectric corrosion.
