Abstract
The utility model discloses a kind of novel high-pressure pipe joint, comprises sleeve pipe and intubate, and intubate inserts sleeve pipe, and it is characterized in that: described cover tube neck has step, and step is provided with thread bush, described bushing head plane has annular heavy stand; Described intubate neck is provided with the threaded connector matched with the thread bush of sleeve pipe, and described intubate head is provided with elastic seal ring, and described elastic seal ring outer wrap has hair fiber braiding layer, and described elastic seal ring embeds in described annular heavy stand.The utility model adopts bell and spigot frame, this structure inherently has sealing effectiveness, there is the sealing ring of hair fiber braiding layer to seal by outer wrap again, utilize large surface tension and the corrosion resistance of hair fiber, considerably increase service life and the sealing effectiveness of sealing ring.Make pipe joint can bear higher sealing load, use less sealing ring just can realize good sealing effectiveness simultaneously.
Description
Technical field
The utility model relates to a kind of novel high-pressure pipe joint.
Background technology
Existing high-pressure pipe connector, common form is that joint and adapter are linked together by connector, is provided with seal between joint and adapter.This sealing structure effect is seal, and the pressure born is also on seal.Therefore require higher to the thickness of seal and material.
Summary of the invention
The utility model object is to provide a kind of structure simple for the defect of prior art, patches conveniently, the novel high-pressure pipe joint that sealing effectiveness is good.
The utility model for achieving the above object, adopts following technical scheme:
A kind of novel high-pressure pipe joint, comprises sleeve pipe and intubate, and intubate inserts sleeve pipe, and it is characterized in that: described cover tube neck has step, and step is provided with thread bush, described bushing head plane has annular heavy stand; Described intubate neck is provided with the threaded connector matched with the thread bush of sleeve pipe, and described intubate head is provided with elastic seal ring, and described elastic seal ring outer wrap has hair fiber braiding layer, and described elastic seal ring embeds in described annular heavy stand.
It is further characterized in that: described elastic seal ring is O shape rubber seal.
Further: the diameter of the annular heavy stand of described bushing head is greater than O shape rubber seal external diameter, and described annular heavy stand height is less than O shape rubber seal diameter of section.
The utility model adopts bell and spigot frame, this structure inherently has sealing effectiveness, there is the sealing ring of hair fiber braiding layer to seal by outer wrap again, utilize large surface tension and the corrosion resistance of hair fiber, considerably increase service life and the sealing effectiveness of sealing ring.Make pipe joint can bear higher sealing load, use less sealing ring just can realize good sealing effectiveness simultaneously.
Accompanying drawing explanation
Fig. 1 is that the utility model is separated schematic diagram.
Fig. 2 is the utility model combination schematic diagram.
Fig. 3 is sealing ring schematic diagram.
Detailed description of the invention
A novel high-pressure pipe joint as shown in Figure 1, 2, comprise sleeve pipe 1 and intubate 2, intubate 2 inserts sleeve pipe 1, and described sleeve pipe 1 neck has step, step is provided with thread bush 3, and described bushing head plane has annular heavy stand 4; Described intubate 2 neck is provided with the threaded connector 5 matched with the thread bush 3 of sleeve pipe 1, described intubate 2 head is provided with O shape rubber seal 6, described O shape rubber seal 6 outer wrap has hair fiber braiding layer 61(as shown in Figure 3), described O shape rubber seal 6 embeds in described annular heavy stand 4.The diameter of the annular heavy stand 4 of described sleeve pipe 1 head is greater than O shape rubber seal 6 external diameter, and described annular heavy stand 4 is highly less than O shape rubber seal 6 diameter of section.
During use, intubate is inserted sleeve pipe, O shape rubber seal embeds in annular heavy stand, and because intubate head has guide effect, and the diameter of annular heavy stand is greater than O shape rubber seal external diameter, and therefore, intubate very easily can insert sleeve pipe, and resistance is less.Again by thread bush and threaded connector acting in conjunction, reduce the distance between intubate and sleeve pipe, extruding O shape rubber seal, makes O shape rubber seal be out of shape and is full of annular heavy stand, played hermetic effect.
