Abstract
The utility model relates to a high-pressure connector which is used for connecting two high-pressure pipe fittings. The connector comprises a metal female head, a pressing nut and a metal male head, wherein the metal female head is used for being connected with one high-pressure pipe fitting, the pressing nut is buckled on the outer edge of the female head, the metal male head is used for being connected with the other high-pressure pipe fitting and is in thread connection into the pressing nut to enable one end of the metal male head to be connected with one end of the female head in a pressing fit mode in the pressing nut, and then the two high-pressure pipe fittings can be communicated. Any sealing element made of rubber materials is not used in the high-pressure connector, the high-pressure connector can reach the sealing effect under the high pressure, and compared with a sealing ring made of rubber materials, the high-pressure connector is more resistant to corrosion in sealing, capable of adapting to the worse environment and more durable, and the junction of the connector and the pipe fittings is not prone to being damaged when being impacted.
Description
Technical field
The utility model relates to a kind of high pressure joint of the quick connection for pressure duct.
Background technique
In prior art, joint is widely used in the connection between pipe fitting, and especially, for the connection of high-voltage and ultra-high pipeline, the requirement of its butt joint is stricter.The current rapid pipe joint for high pressure all adopts and rubber seal is set in joint to realize sealing, yet after use a period of time, rubber ring easily damages, thereby loses sealing effect., need to improve this joint at present, to meet use needs for this reason.
Model utility content
The problem existing in order to solve above-mentioned prior art, the utility model aims to provide a kind of high pressure joint of simple in structure, easy care, to overcome rubber seal in existing sealing ring type high pressure joint, easily damage, need often to safeguard the shortcoming of changing seal ring, to meet under the prerequisite of pressure requirement, increase working life.
A kind of high pressure joint described in the utility model, it is for connecting two high-pressure pipe members, and described joint comprises:
One metal female for being connected with a described high-pressure pipe member;
One spiral-lock is at the gland nut of described female outer rim; And
One metal male for being connected with high-pressure pipe member described in another root, it is threaded in described gland nut, so that its one end is connected with one end compression fit of described female in described gland nut, and two described high-pressure pipe members is communicated with.
In above-mentioned high pressure joint, one end of described female is stretched in this gland nut from an end face of described gland nut, in the outer rim of this female and the position of contiguous its one end is provided with a boss, this boss mates with the inner wall shape of described gland nut, and is resisted against on an end face of this gland nut.
In above-mentioned high pressure joint, one end of described female is provided with reentrant part, and one end of described male is provided with the lug boss in the reentrant part that is pressed on described female.
In above-mentioned high pressure joint, the surface of contact of the female portion and described lug boss is cambered surface.
In above-mentioned high pressure joint, the surface of contact of the female portion and described lug boss is the conical surface.
Owing to having adopted above-mentioned technical solution, the utility model is usingd female as carrier, gland nut is buckled in female, then be screwed in male, thereby connect this male and female, and play and make female compress with male the effect being connected, because the adjacent Metal Contact face of female and male directly contacts sealing, and do not adopt the seal element of any quality of rubber materials, thereby make this high pressure joint can not only reach the sealing effect under high-pressure, and more corrosion-resistant than the seal ring sealing of rubber material, can adapt to worse environment, more durable, and the jointing of joint and pipe fitting is not easy to cause damage because of collision.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of a kind of high pressure joint of the utility model.
Embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present utility model, and be described in detail.
As shown in Figure 1, a kind of high pressure joint, it is for connecting for example oil pipe of two high-pressure pipe member 4(), this joint comprises: the female 3 of the male 1 of metal, gland nut 2 and metal, wherein, female 3 is connected with a high-pressure pipe member, and male 1 is connected with another root high-pressure pipe member.
Specifically, one end of female 3 is stretched in this gland nut 2 from an end face of gland nut 2, in the outer rim of this female 3 and position of contiguous its one end is provided with a boss 31, this boss 31 mates with the inner wall shape of gland nut 2, and be resisted against on an end face of this gland nut 2, thereby make gland nut 2 spiral-locks in the outer rim of female 3.
When mounted, first by gland nut 2 spiral-locks in female 3, then male 1 is screwed into gland nut 2, and the reentrant part 32 of its lug boss 11 and female 3 is compressed be connected, finally high-pressure pipe member be connected with female 3 respectively at male 1.
High pressure joint of the present utility model can have following parameter:
1, material: stainless steel 304;
2, maximum service pressure: 140MPa;
3, maximum bursting pressure: 300MPa;
4, temperature :-30 ℃ to+100 ℃;
5, effective drift diameter: 4.0mm;
6, at pressure, will be flow under 0.5MPa: 8.5L/min.
High pressure joint of the present utility model adopts stainless steel material (Hardened Steel zinc-plating material) to make, and adopt screw thread spinner to connect, make male directly contact sealing with female, make thus a whole set of joint there is no effective connection of rubber seal, thereby avoided the problem of the leakage that damage brings of rubber seal, improved sealability, and meeting under the prerequisite of pressure requirement, wear-resistant, corrosion-resistant, make product not fragile, and install more convenient.
Above-described, be only preferred embodiment of the present utility model, not in order to limit scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Be that simple, the equivalence that every claims according to the utility model application and description are done changes and modify, all fall into the claim protection domain of the utility model patent.The utility model not detailed description be routine techniques content.
