Abstract
The invention discloses a novel high-pressure pipe joint. The novel high-pressure pipe joint includes a sleeve and an inserted pipe, wherein the inserted pipe is inserted into the sleeve. The novel high-pressure pipe joint is characterized in that the neck of the sleeve is provided with a step, a threaded sleeve is arranged on the step, and a ring-shaped sunk platform is arranged on the plane at the head of the sleeve; a threaded connector is arranged at the neck of the inserted pipe and matched with the threaded sleeve of the sleeve; an elastic seal ring is arranged at the head of the inserted pipe, wrapped with a hair fiber woven layer, and inserted into the ring-shaped sunk platform. The novel high-pressure pipe joint adopts the bell-spigot structure which has the original sealing effect, and the seal ring wrapped with the hair fiber woven layer is further used for sealing, so that the large surface tension and high corrosion resistance of hair fibers can greatly prolong the service life of the sealing ring and improve the sealing effect of the sealing ring. Therefore, the pipe joint can bear a higher seal pressure, and good sealing effect can be achieved through the sealing ring with a smaller size.
Description
Technical field
The present invention relates to a kind of novel high-pressure pipe joint.
Background technique
Existing high-pressure pipe connector, common form is that joint and adapter are linked together by link, is provided with Sealing between joint and adapter.This sealing structure effect is Sealing, and the pressure born is also on Sealing.Therefore require higher to the thickness of Sealing and material.
Summary of the invention
The object of the invention is to provide a kind of structure simple for the defect of prior art, patches conveniently, the novel high-pressure pipe joint that sealing effect is good.
The present invention for achieving the above object, adopts following technological 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 present invention adopts bell and spigot frame, this structure inherently has sealing effect, there is the seal 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 working life and the sealing effect of seal ring.Make pipe joint can bear higher sealing load, use less seal ring just can realize good sealing effect simultaneously.
Accompanying drawing explanation
Fig. 1 is that the present invention is separated schematic diagram.
Fig. 2 is that the present invention combines schematic diagram.
Fig. 3 is seal ring schematic diagram.
Embodiment
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 leading role, 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.
