Description
Technical field
The utility model relates to a kind of water knife device parts, and specifically a kind of water knife device is carried swivel joint with high-pressure water.
Background technique
In water cutter working procedure, the position of cutting head constantly is subjected to displacement, correspondingly carry the outlet pipe of high pressure water also must move thereupon, and outlet pipe is generally the rigidity pressure pipe, for guaranteeing the conformity of outlet pipe and cutting head, outlet pipe must move or rotate with cutting head, generally intake pipe is owing to be high-pressure water pipe, all be in stationary state for the sake of security, this just must use and can make outlet pipe make the swivel joint that is used to connect intake pipe and outlet pipe that rotates with respect to intake pipe.And existing rotary joint structure complexity is oversize, makes, assembles difficulty, and cost is too high.
Summary of the invention
The purpose of this utility model be design a kind of simple in structure, size is little, manufacturing, novel water knife device easy to assembly are carried swivel joint with high-pressure water.
The technical solution of the utility model is:
A kind of water knife device is carried swivel joint with high-pressure water, comprise and to make the water inlet valve body 2 and the water outlet valve body 1 that rotate freely relatively, the two cooperates with annular boss by annular groove and links to each other, water intake 11 is positioned at on the water valve body 2, water outlet 12 is positioned on the water outlet valve body 1, it is characterized in that water intake 11 and water outlet 12 communicate by osculum 13 and the water inlet 14 that communicates with the endoporus 17 of mandrel 3 respectively, one end and the water outlet valve body 1 of mandrel 3 are fixedly linked, the other end inserts in the Seal cage 15 of water inlet valve body 2, in Seal cage 15,14 positions, water inlet on the mandrel 3 are set with water guide pad 4, respectively are symmetrically installed with one group of black box 16 on the mandrel 3 of water guide pad 4 two sides.
The utility model has further been taked following technical measures:
Black box 16 comprises taper ring 6, seal ring 5 and supporting ring 7, and an end of supporting ring 7 and an end of taper ring 6 offset, and the inwall end face of the other end and Seal cage 15 offsets, and an end of seal ring 5 contacts with water guide pad 4, and taper ring 6 is sleeved on the seal ring 5.
Mandrel 3 contacts surface roughness Ra partly smaller or equal to 0.2 μ m with black box 16.
Mandrel 3 is made up of butt end and thin end, and butt end is arranged in water outlet valve body 1, and the large part of thin end is in water inlet valve body 2.
The beneficial effects of the utility model:
1, compact structure, size is little: this joint overall dimension only is that it is very little to take up room about Φ 40 * 70mm, can be installed at an easy rate on the various rotating machinerys.
2, the life-span long, reliable in structure: because the swivel joint main body is not subjected to hydraulic pressure substantially, high pressure water is mainly passed through by the endoporus in the mandrel 3 17.The surface roughness Ra of mandrel 3 is controlled at below 0.2, the life-span when guaranteeing with black box 16 rotary seals.The conical surface of high-pressure seal ring and taper ring compresses mutually, the radial component of water pressure just acts on the Sealing like this, compress with mandrel 3, guarantee sealing effect, when high-pressure seal ring is frayed, same effect owing to this axial thrust load, seal ring can be compressed (promptly playing automatic compensating action) further, up to excessive wear, till the seal failure.The main body of swivel joint of the present utility model (promptly intake valve body 2 and water outlet valve body 1) can adopt high-strength stainless steel to make, and Sealing adopts ultrahigh pressure special-purpose nylon material, cooperates aforesaid automatic compensation mechanism, can fully guarantee its working life.
