Abstract
The utility model discloses a hydraulic pipeline which comprises flexible pipes and is characterized by further comprising a connection part. Two ends of the connection part are respectively communicated with the flexible pipes, the two flexible pipes are communicated through the connection part, the connection parties a clamp sleeve type connection part, and the flexible pipes are sleeved and clamped on the connection part. In the hydraulic pipeline, a sealing ring is positioned at the connection position. The connection position is sealed by the sealing ring, so that the hydraulic pipeline is good in sealing effect. An O-shaped ring is utilized and arranged in a clamp groove of the O-shaped ring. When relative displacement between a connection disk and a flange disk happens, the edge of an accommodation groove can extrude the O-shaped ring to enable the O-shaped ring to deform. The deformed O-shaped ring enables the connection disk and the flange disk to be tightly contacted, so that sealing performance is good.
Description
Technical field
The utility model relates to a kind of hydraulic pipe line.
Background technique
The hydraulics application is very extensive.Hydraulics utilizes hydraulic oil to transmit pressure.The conveying of hydraulic oil is very crucial in hydraulics.Hydraulic oil generally uses flexible pipe to carry.And, generally all adopt many flexible pipes to interconnect and form.Hydraulic oil has higher pressure.Linkage structure between the flexible pipe of the prior art is complicated, install and use equal inconvenience, and the sealing of joint is poor, causes leakage easily.In use, be easy to generate relative displacement between the interconnective flexible pipe or between flexible pipe and the link, cause leakage when producing relative displacement more easily.The conveying of hoses leak grievous injury hydraulic oil.
The model utility content
First purpose of the utility model is in order to overcome deficiency of the prior art, the hydraulic pipe line of a kind of joint good airproof performance to be provided.
For realizing above purpose, the utility model is realized through following technological scheme.
Hydraulic pipe line comprises flexible pipe, it is characterized in that, also comprises link, said link two ends respectively with soft pipe connection; Two flexible pipes are communicated with through link; Said link is the FERRULETYPE link, and the flexible pipe suit also is fastened on the link.
Preferably, said hose is provided with flange plate, and said link is provided with land; Said flange plate is connected with land.
Preferably, said flange plate and land removably connect through bolt or screw.
Preferably, be provided with Sealing between described land and the flange plate.
Preferably, described Sealing is an O type circle.
Preferably, described flange plate is provided with first containing groove; Described land is provided with second containing groove; First containing groove is relative with the second containing groove position; Described O type circle is positioned at first containing groove and second containing groove.
Hydraulic pipe line in the utility model is provided with seal ring in the joint, utilizes the seal ring place that is tightly connected, good sealing effect.Adopt O type circle, and O type circle is arranged in the draw-in groove, when land and flange plate generation relative displacement, the edge extruding O type circle of containing groove makes the distortion of O type circle.It is tightr that O type circle after the distortion and land contact with flange plate, and sealability is better.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with embodiment the utility model is carried out detailed description:
As shown in Figure 1, hydraulic pipe line comprises that the flexible pipe 1 of flexible pipe more than 1, two more than two connects through link, adopts 90 degree links 3 in the present embodiment.The two end part 31 of link 3 are communicated with a flexible pipe 1 respectively.Link 3 is the FERRULETYPE link, and flexible pipe 1 suit also is fastened on the end 31 of link 3.
Flexible pipe 1 end is provided with flange plate 2, and flange plate 2 is provided with first containing groove 21.Link 3 is provided with two lands 4; Each land 4 is provided with second containing groove 41.Flange plate 2 removably connects through bolt or screw (not shown) with land 4.Be provided with O type circle 5 between flange plate 2 and the land 4.Flange plate 2 is with after land 4 is connected, and first containing groove 21 is relative with second containing groove, 41 positions; O type circle 5 is positioned at first containing groove 21 and second containing groove 41.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
