Abstract
The invention discloses a high-pressure pipe joint which comprises a casing and an inserting pipe, wherein the inserting pipe is inserted into the casing. The high-pressure pipe joint is characterized in that a step is arranged on a neck of the casing; a threaded sleeve is arranged on the step; an annular sunk platform is arranged on a plane at a head of the casing; a threaded connection head matched with the threaded sleeve of the casing is arranged at a neck of the inserting pipe; an elastic sealing ring is arranged at a head of the inserting pipe; an annular groove is formed in a sealing contact surface of the elastic sealing ring and filled with a hair fiber braided ring; and the elastic sealing ring is embedded into the annular sunk platform. The joint employs a bell-spigot-bell structure which has a sealing effect, the sealing ring with the hair fiber braided ring is filled for sealing, large surface tension and corrosion resistance of a hair fiber are utilized, and the service life and a sealing effect of the sealing ring are greatly prolonged and improved. The pipe joint can bear higher sealing pressure, and at the same time, the good sealing effect can be achieved by using the smaller sealing ring.
Description
Technical field
The present invention relates to a kind of high-pressure pipe connector.
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 high-pressure pipe connector that sealing effect is good.
The present invention for achieving the above object, adopts following technological scheme:
A kind of high-pressure pipe connector, 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, described intubate head is provided with elastic seal ring, described elastic seal ring sealing contact surface has annular recess, be filled with hair fiber braided ring in described annular recess, 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, seal ring again by being filled with hair fiber braided ring seals, and utilizes large surface tension and the corrosion resistance of hair fiber, considerably increases 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 high-pressure pipe connector 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 surface of contact has annular recess, hair fiber braided ring 61(is filled with as shown in Figure 3 in described annular recess), 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.
Claims (3)
1. a high-pressure pipe connector, 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, described intubate head is provided with elastic seal ring, described elastic seal ring sealing contact surface has annular recess, be filled with hair fiber braided ring in described annular recess, described elastic seal ring embeds in described annular heavy stand.
2. high-pressure pipe connector according to claim 1, is characterized in that: described elastic seal ring is O shape rubber seal.
