Abstract
一种液压系统管路连接装置，螺母、卡套及O型圈依次装到硬管上，再把螺母5拧到接头上，拧到合适的拧紧力矩后，卡套挤入到硬管内，使得硬管不能退出螺母，这时，O型圈挤压在接头的追面上，采用卡套和密封线圈连接管路时，不再受焊接条件和扩口设备的制约，使液压管路加工变得简单低廉。使密封可靠耐用，能承受高压、抗冲击震动。液压系统的漏油问题得到切底解决。
A hydraulic system pipeline connection device. Nuts, ferrules and O-rings are installed on the hard pipe in sequence, and then the nut 5 is screwed onto the joint. After screwing to an appropriate tightening torque, the ferrule is squeezed into the hard pipe, so that The hard pipe cannot withdraw from the nut. At this time, the O-ring is squeezed on the backing surface of the joint. When the ferrule and the sealing coil are used to connect the pipeline, it is no longer restricted by the welding conditions and the flaring equipment, so that the processing of the hydraulic pipeline becomes easier. Simple and cheap. Make the seal reliable and durable, able to withstand high pressure, shock and vibration. The oil leakage problem of the hydraulic system has been completely solved.
Description
Technical field
The utility model relates to a kind of pipeline connecting device, especially the hydraulic system pipeline connection set.
Background technique
The hydraulic system pipeline connection set has welding type, flared type and FERRULETYPE at present.These three kinds of connection sets respectively have pluses and minuses:
Welding type connects reliable, and is high pressure resistant, but processed complex needs argon or other inert-gas arc weldings to connect;
Flared type connects simple, but need have the expensive enlarging equipment of specialty to guarantee the enlarging quality, otherwise sealability and withstand voltage properties are poor;
The FERRULETYPE linkage structure is simple, but its antivibration weak effect, the outside dimension to hard tube when connecting hard tube requires height, and sealing effect is poor.
Summary of the invention
The utility model is in order to solve above-mentioned technical deficiency, and a kind of simple in structure, easy to operate, good airproof performance, cheap hydraulic pressure road under the overall leadership connection set are provided.
For the technological scheme that realizes that the utility model adopts: a kind of hydraulic system pipeline connection set, comprise joint, hard tube, nut, cutting ferrule and O type circle, described nut, cutting ferrule and O type circle are connected on the hard tube successively, and joint links to each other with hard tube.
Described nut is screwed on the joint.
Described cutting ferrule is clamp-oned in the hard tube.
Described O type circle is squeezed on the conical surface of joint.
Nut, cutting ferrule and O type circle are connected on the hard tube successively, and joint links to each other with hard tube, and nut is screwed on the joint, and cutting ferrule is clamp-oned in the hard tube, and O type circle is squeezed on the conical surface of joint.
Advantage of the present utility model: when adopting cutting ferrule and encapsulated coil connecting pipeline, no longer be subjected to the restriction of welding condition and enlarging equipment, make hydraulic pipe line processing become simply cheap.Make sealing reliability and durability, can bear high pressure, shock resistance vibrations.The hydraulic leak problem obtains cutting end solution.
These model utility promotion and application will have a tremendous social and economic benefits to the every field of hydraulic system.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
1-joint, 2-hard tube, 3-O type circle, 4-cutting ferrule, 5-nut.
Embodiment
Structural drawing of the present utility model shown in Figure 1 is comprising 1, hard tube 2, nut 5, cutting ferrule 4 and coil 3.
The concrete order of connection: nut 5, cutting ferrule 4 and O type circle 3 install on the hard tube 2 successively, again nut 5 is screwed on the joint 1, after getting to suitable screw-down torque, cutting ferrule 4 is squeezed in the hard tube 2, make hard tube 2 can not withdraw from nut 5, at this moment, O type circle is squeezed on the conical surface of joint 1, plays the effect of sealing.
