Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1 is axle head, and 2 is that 3 is aqueduct at a distance from post, and 4 is major axis, and 5 is faucet, and 6 is water inlet tap, and 7 is water entry, and 8 is water exit, and 9 are the awl post.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail.
As shown in Figure 1; The utility model comprises axle head 1, separated post 2, aqueduct 3, major axis 4, faucet 5 and water inlet tap 6, and wherein an end inside of major axis 4 has blind hole, and the opening end of this blind hole is connected with the axle head 1 that same inside is provided with blind hole; On the major axis 4 on the opening end of blind hole and the axle head 1 opening end of blind hole be threaded fixing earlier; Adopt brazing again, and the postwelding machining, form and position tolerance guaranteed.In the space that two blind hole butt joints of major axis 4 and axle head 1 are formed, be provided with aqueduct 3, this aqueduct 3 can be hollow circuit cylinder, is positioned at the inside of major axis 4, and is threaded with major axis 4; The sealing of one end of this aqueduct 3 is connected to the blind hole bottom of major axis 4, and the other end of aqueduct 3 is free end, near the blind hole bottom of axle head 1, and the free end of aqueduct 3 is radial; Being water exit 8 between the inwall of said aqueduct 3 and major axis 4, is water entry 7 in the aqueduct 3, and this water entry 7 is connected with water exit 8 at the said free end of aqueduct 3; The other end at major axis 4 is respectively equipped with faucet 5 that is communicated with water exit 8 and the water inlet tap 6 that is communicated with water entry 7.The utility model is the welding integral piece, and faucet 5 and water inlet tap 6 are welded on the other end of major axis 4 respectively, are positioned at the left and right sides of major axis 4 axial cross sections; During welding; Faucet 5 and water inlet tap 6 are obliquely installed with major axis 4 respectively; Be that angle between the central axis of faucet 5 and one section the central axis that major axis 4 has blind hole is the obtuse angle, the angle between the central axis of the central axis of water inlet tap 6 and aqueduct 3 is the obtuse angle; Obtuse angle between the central axis of the central axis of faucet 5 and water inlet tap 6 and major axis 4 central axis is the bigger the better under the situation that workpiece allows, and angle is big more, and head loss is more little.The central axis conllinear of the central axis of the blind hole on the major axis 4 and major axis 4; The central axis conllinear of the central axis of the blind hole on the axle head 1 and axle head 1; The central axis conllinear of the central axis of the central axis of major axis 4, axle head 1 and aqueduct 3, thus guarantee that current are smooth and easy.
The blind hole opening end of axle head 1 is threaded with the blind hole opening end of major axis 4, and the blind hole bottom central of axle head 1 extends upward, forms awl post 9 vertically, and insert in the free end of aqueduct 3 at the top of this awl post 9.The utility model is respectively the knuckle structure at the flow direction-changing place of axle head 1, major axis 4 and aqueduct 3; Current are because the change of local boundary shape and size produces whirlpool like this; Make current in subrange, produce bigger power loss and drop to minimum; Can farthest reduce head loss like this, also can reduce the possibility that produces vibrations thus.Be specially: the blind hole bottom around the awl post 9 is knuckle, and major axis 4 is knuckle with the junction of faucet 5 and water inlet tap 6, and the effect of guiding current is mainly played in this two places design, reduces head loss and vibrations; The blind hole bottom of major axis 4 is a knuckle, can make current smooth and easy.
Be welded with at least two near free-ended outside surface at a distance from posts 2 at aqueduct 3, this at a distance from post 2 in the blind hole of axle head 1, be distributed on the outside surface of aqueduct 3 axial cross sections, connect at a distance from the inwall of post 2 with axle head 1.
The material of the utility model axle head 1 is a copper, and the material of separated post 2, aqueduct 3, major axis 4, faucet 5 and water inlet tap 6 is stainless steel.
The principle of work of the utility model is:
Locate in the termination of axle head 1 (being the outside surface of axle head 1 the other end) with the molybdenum transition piece with being threaded, be connected with seed crystal on the molybdenum transition piece, seed crystal contacts with sample; Under about 2200 ℃～2300 ℃ operating mode of temperature, water-cooled axle water flow stationary, water-cooled is respond well; But non-stop run 15～30 days or longer time, can grow the crystal of the quality product matter of about 160Kg, and not take off crystal in the course of the work; The crystal pulling process is steady, also can conveniently take a sample after the crystal moulding, and molybdenum web member and water-cooled axle are easy for installation.
The separated post 2 of the utility model is welded on the free end of aqueduct 3, no matter guarantees that major axis 4 has how long (the actual requirement of equipment), all can make aqueduct 3 not inclined to one side when work, make the central axis of aqueduct 3 and the central axis conllinear of major axis 4, thereby the assurance current is smooth and easy; And current flow out or 180 ° of flow direction-changings in, ducted water flow velocity increases, and causes the resistance of current piping to become big; The resistance change causes the flow velocity of water slack-off greatly, and after water flow velocity was slack-off, resistance reduced; Cause water flow velocity to accelerate again, in one fast one slow process, aqueduct 3 just possibly produce vibrations; Produce vibrations and can eliminate vibrations at any time after post 2, the robust motion of the water-cooled axle of assurance; Faucet 5 is obliquely installed with water inlet tap 6, can reduce head loss.
