Abstract

The utility model relates to a connecting structure of a flaring type pipe and a non-flaring type pipe. The connecting structure of the flaring type pipe and the non-flaring type pipe is characterized in that a direct connection pipe joint is installed between the flaring type pipe and the non-flaring type pipe, one end of the direct connection pipe joint is provided with a pipe joint end socket of a flaring type pipe adapting piece, and the pipe joint end socket enables the direct connection pipe joint to be connected with the flaring type pipe adapting piece. The flaring type pipe is provided with a flat nozzle and a first jacket nut after the flaring type pipe is spinned over. The other end of the direct connection pipe joint is provided with the pipe joint end socket of a non-flaring type pipe adapting piece, and the pipe joint end socket enables the direct connection pipe joint to connect with the non-flaring type pipe adapting piece. The non-flaring type pipe is provided with a second jacket nut after the non-flaring type pipe and a pipe sleeve are preassembled. The connecting structure of the flaring type pipe and the non-flaring type pipe solves the connection of the flaring type pipe and the non-flaring type pipe, is convenient to operate and simple in structure, and can achieve serialization production.

Description

A kind of flared type conduit with without the linkage structure of flared type conduit
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of flared type conduit with without the linkage structure of flared type conduit.
Background technique
At present hydraulic system, pressure system and other fluid delivery systems of China's aerospace flight vehicle, aerospace equipment and other machinery often need to adopt simultaneously flared type with without the flared type pipe joint element, for guaranteeing the reliable connection between these multi-form pipe joint elements, need the applicable linkage structure of design.
The model utility content
The technical problems to be solved in the utility model just provide a kind of flared type conduit with without the linkage structure of flared type conduit.
A kind of flared type conduit with without the linkage structure of flared type conduit, this linkage structure is: establish a free flow coupling at the flared type conduit with between without the flared type conduit, one end of this free flow coupling has the pipe joint termination of flared type pipe joint element, and it can be connected with the flared type pipe joint element; After the enlarging of described flared type conduit with flat ozzle and cap nut one; Have pipe joint termination without the flared type pipe joint element at the other end of described free flow coupling, make its can be connected without the flared type pipe joint element, described without after flared type conduit and the pipe box preassembly with cap nut two.
Adopt the utility model linkage structure, solved the flared type conduit with without being connected between the enlarging conduit, it is easy to operate, and is simple in structure, but also can producing in serial form.
Description of drawings
Fig. 1 is the utility model flared type conduit and the structural representation that is connected without the flared type conduit.
Embodiment
At machine industry, because connecting duct is of a great variety in the equipment such as hydraulic system, pressure system, not only to consider the reliability that connects, also to consider the connection between the different size conduit.As shown in Figure 1, the utility model provide a kind of flared type conduit with without the linkage structure of flared type conduit, this linkage structure is for establishing a free flow coupling 4 at flared type conduit 1 with between without flared type conduit 7, one end of this free flow coupling 4 has the pipe joint termination of flared type pipe joint element, it can be connected with the flared type pipe joint element because after 1 enlarging of flared type conduit with flat ozzle 2 and cap nut 1; The other end of free flow coupling 4 has the pipe joint termination without the flared type pipe joint element, make its can be connected without the flared type pipe joint element because without after flared type conduit 7 and pipe box 6 preassembly with cap nut 25.
The physical dimension of free flow coupling 4 will fully take into account external diameter and the wall thickness of hydraulic system, pneumatic system and other fluid systems of aerospace equipment and other machinery all size conduit commonly used, determine free flow coupling boundary dimension according to conduit size uniting conduit Maximum operating pressure, and will carry out intensity by the hydraulic pipe strength calculation formula to the free flow coupling of each specification and calculate.
Select the material of free flow coupling 4 according to following situations:
1) free flow coupling 4 is in the hydraulic system of aerospace equipment and other machinery, the enlarging of pneumatic system and other fluid systems with without the actual conditions of enlarging pipe joint element work be: when the outside thread of the internal thread of cap nut and free flow coupling 4 is tightened, free flow coupling 4 is wanted to bear the larger axial force by the screw-down torque generation, when after repeatedly the outside thread of the internal thread of cap nut and free flow coupling 4 being tightened, taking apart again, the screw thread of free flow coupling should not make a difference the distortion used to guarantee that can repeat assembling uses, and this just requires free flow coupling 4 to have certain intensity.
2) hydraulic system, pneumatic system and other fluid system enlargings of aerospace equipment and other machinery are generally with material category without enlarging conduit connecting duct: stainless steel, aluminum alloy and titanium alloy.This just requires the material of free flow coupling 4 to adapt with the material of the flat ozzle 2 that is used in conjunction with, cap nut 1, cap nut 25 and pipe box 6, does not namely produce stress corrosion after the contact.
The utility model flared type conduit with have the following advantages without the linkage structure of enlarging conduit:
1), successfully realized the flared type pipe joint element with without being connected between the flared type pipe joint element, and realized seriation.Can save a large amount of design times after the application, thereby accelerate Development Schedule, saving development cost, obtain preferably economic benefit.
2), because free flow coupling 4 has adopted preferably material of combination property, can realize repeatedly repeating assembling and use.

Claims (1)

1. a flared type conduit and linkage structure without the flared type conduit, it is characterized in that: this linkage structure is: establish a free flow coupling (4) at described flared type conduit (1) with between without flared type conduit (7), one end of this free flow coupling (4) has the pipe joint termination of flared type pipe joint element, and it can be connected with the flared type pipe joint element; After described flared type conduit (1) enlarging with flat ozzle (2) and cap nut one (3); Have pipe joint termination without the flared type pipe joint element at the other end of described free flow coupling (4), make its can be connected without the flared type pipe joint element, described without after flared type conduit (7) and pipe box (6) preassembly with cap nut two (5).
