Description
Technical field
This utility model relates to a kind of hard pipe coupling component of hydraulic system, particularly relates to a kind of hard pipe coupling component of high-pressure hydraulic.
Background technology
Hydraulic system because having that simple in construction, volume are little, lightweight, response speed fast, High power output, stepless speed regulation can be conveniently realized, easily realize frequently commutation, easily realize the advantages such as automatization, make it from civilian to national defence, from being generally transferred to the control system that degree of accuracy is significantly high, it is obtained for and is widely applied.
Due to hydraulic system operationally, the characteristic such as the impact of pressure, the passage of time, vibrations, temperature, often cause hydraulic system pipeline to reveal, energy waste, contaminated environment. And also affect the safety of system work, reliability, increase the downtime of machine, reduce productivity ratio, increase production cost and product caused stained. Therefore, the leakage to hydraulic system pipeline, it is necessary to prevented and control.
Traditional hydraulic system hard tube connects mainly three kinds of modes, welding type is owing to should produce welding slag contaminated system, substantially it is eliminated, and conventional having two kinds of forms, one is bite type, and another kind is flared type, as shown in Figure 1, for bite type hydraulic system hard tube connecting component structure schematic diagram a kind of in prior art, the described hard pipe coupling component of bite type hydraulic system includes the transit joint body 11 of 24 �� of bellmouths, with cutting ferrule 12 and the nut 13 of sharp-pointed inner edge. After described cutting ferrule 12 and described nut 13 are enclosed within precision seamless steel tubes 14 and insert described transit joint body 11, screw described nut 13, due to the effect of the internal taper hole of described transit joint body 11 and described nut 13 back taper, described cutting ferrule 12 rear portion is made to be stuck on tube wall and play retaining effect; Meanwhile, before described cutting ferrule 12 in cutting edge incision tube outer wall, the effect of sealing and anti-pull-off is served.This hard pipe coupling component of bite type hydraulic system has a simple in construction, the advantage such as easy to use. But, cutting edge incision pipe place before described cutting ferrule 12, owing to have employed rigid seal, often due to impacting with high pressure, described cutting ferrule 12 pretightning force are excessive or too small cause leakage of oil, there will be described nut 13 under extreme case and collapse, cause danger. Simultaneously, it may have easily permeability, leakage of oil, pretightning force strictly require the shortcomings such as higher to making.
As in figure 2 it is shown, be another kind of flared type hydraulic system hard tube connecting component structure schematic diagram in prior art, the described hard pipe coupling component of flared type hydraulic system includes the transit joint body 21 of 74 �� of male cone (strobilus masculinus)s, plays nut 22 and the pipe box 23 of pressuring action. After described pipe box 23 and described nut 22 are enclosed within precision seamless steel tubes 24, with pipe-expanding machine, tube end expanded into 37 �� of conical surfaces, insert described transit joint body 21 and screw described nut 22, described pipe box 23 is stuck in precision seamless steel tubes outer wall, serve the effect of anti-pull-off, described transit joint body 21 is pressed on 37 �� of conical surfaces, forms metallic sealing section. The advantages such as this hard pipe coupling component of flared type hydraulic system has making and requires low, and sealing is better, easy to use. But the limitation due to metallic sealing section; often can there is the phenomenon of permeability due to the reason duration such as vibrations, sealing surface roughness, angle in sealing surface; and once there is the permeability situation owing to metal sealing surface roughness problem causes; only by changing transit joint body or the method for precision seamless steel tubes again enlarging being solved, it is very inconvenient to keep in repair.
