Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation, it is therefore an objective to help those skilled in the art have to the design of the utility model, technical solution it is more complete, accurate and
Deep understanding, and contribute to its implementation.
As shown in Figure 1 to Figure 3, the utility model provides a kind of forklift multi-way valve oil tube connection device, including 1 He of oil pipe
For the link bolt 2 being connected with multi-way valve, oil pipe includes articulated joint 11 and the oil pipe sheet being fixedly connected with articulated joint 11
Body 12, articulated joint 11, which has, allows the fluid cavity 13 that link bolt 2 is inserted into and connect with the oil duct in oil pipe body 12, hingedly spiral shell
Being internally provided with of bolt 2 allows runner 24 that hydraulic oil the enters and runner 24 passes through set through hole on the side wall of link bolt 2
25 connect with fluid cavity 13, and the end face of articulated joint 11 is equipped with the first groove 14 and the bonded washer 3 that accommodate bonded washer 3
It is clipped between articulated joint 11 and link bolt 2.
Specifically, as shown in figures 1 and 3, as preference, link bolt 2 is hexagon flange bolt, the hinged spiral shell
Bolt 2 includes sequentially connected hexagonal bolt head 21, ring flange 22 and screw rod 23, and ring flange 22 is disc-shaped structure, screw rod 23
End surface is equipped with the external screw thread being connected for the valve body screw thread with multi-way valve, and the diameter of ring flange 22 is more than the diameter of screw rod 23
And more than the external diameter of a circle of hexagonal bolt head 21.Link bolt 2 selects hexagon flange bolt, hexagon flange bolt
" bearing area and the ratio of stress area " is greater than conventional hexagonal hook bolt, therefore this bolt can bear higher pretightning force,
Anti-loosening property is also more preferable.
As shown in Fig. 2, fluid cavity 13 set in articulated joint 11 is to start to run through in one end end face of articulated joint 11
To the circular cavity of other end, the screw rod 23 of link bolt 2 makes the threaded end of tool through fluid cavity 13 and protruding
Expose, convenient for being connected with multi-way valve.The diameter of the ring flange 22 of link bolt 2 is more than the diameter of fluid cavity 13,22, ring flange
In the outside of articulated joint 11, bonded washer 3 so as to be clamped in the ring flange 22 of articulated joint 11 and link bolt 2 it
Between, sealing effect is good, and fluid is avoided to reveal.First groove 14 is that the annular set on one end end face of articulated joint 11 is recessed
Slot, the diameter of ring flange 22 are more than the maximum gauge of first groove 14, and bonded washer 3 is embedded in first groove 14, can prevent
Sideslip, it is ensured that the reliability of sealing.Between articulated joint 11 and link bolt 2 bonded washer 3 is selected to be carried out as sealing element
Sealing, bonded washer 3 are usually to be composed of metal material and nonmetallic materials, though nonmetallic materials have softness well
Property, compressibility and the advantages such as bolt load ability is low, but its major defect is that intensity is not high, and resilience is poor, is not suitable for high pressure
High temperature applicationss so with reference to the characteristics of intensity that metal material has is high, resilience is good and is amenable to that high temperature must be played, are formed two
The washer of person's combining structure, so as to improve sealing effect.
As shown in figures 1 and 3, runner 24 is arranged at the inside of the screw rod 23 of link bolt 2, runner 24 and in screw rod 23
End forms opening, and through hole 25 is uniformly arranged in the circumferential direction multiple and by in side on the side wall of the screw rod 23 of link bolt 2
Extend radially through setting on wall, the fluid in oil pipe body 12 is flowed into the fluid cavity 13 of articulated joint 11, then through screw rod 23
Through hole 25 on side wall is flowed into runner 24.
As depicted in figs. 1 and 2, first groove 14 is arranged on one end end face of articulated joint 11, articulated joint 11 it is another
One end end face is equipped with the second groove 15 for accommodating O-ring 4 and the O-ring 4 is used to be clamped in articulated joint 11 and multi-way valve
Between valve body, second groove 15 is the annular groove coaxial with the first groove, and O-ring 4 is embedded in second groove 15, can prevent
Sideslip, it is ensured that the reliability sealed between articulated joint 11 and multi-way valve, sealing effect is good, fluid can be avoided to reveal.
