Abstract
The utility model discloses a water-spraying device in steel pipe which can carry out the inner shaft flow water-spraying cooling in the quenching equipment of steel pipes. A nozzle (5) is a flat cone-shaped short tube whose caliber is reduced gradually, and the eccentricity between a water outlet and a water inlet is 0-50 mm. In working, the nozzle (5) provided with proper eccentricity is arranged on a water-supplying tube (1) according to the standard of a saw tube (6), and the central line of the water outlet corresponds to the shaft line of a steel pipe (6). Cooling water flows through the nozzle (5) from the water-supplying tube (1) and sprays into the steel pipe through one end of the rotating steel pipe (6). At the connecting position of the nozzle (5) and the water-supplying pipe, the calibers are identical, and the central lines are coincident completely. The flow resistance is reduced, and the cooling effect is enhanced.
Description
The utility model relates in a kind of steel pipe quenching apparatus, waterworks in the axial flow water spray refrigerative steel pipe in steel pipe is carried out.
Waterworks is when steel pipe quenches in the steel pipe, from an end of the steel pipe that rotating, the refrigerative device of spraying water in steel pipe.The cylindrical short tube of the many employings of its nozzle form.Owing to the water coolant that sprays in cylindrical short tube has certain angle of divergence, for guaranteeing that water coolant all advances in the people manages, need preparation one cover can make its nozzle moving mechanism that moves forward and backward, nozzle is inserted in the steel pipe quench, to the structure complicated that makes waterworks in the steel pipe.In the prior art, waterworks adopts the conical short tube of bore convergent as nozzle in some steel pipe.Owing to the water coolant angle of divergence that sprays in conical short tube is less, even nozzle and pipe end have certain interval, water coolant still can all spray in the steel pipe, therefore can cancel nozzle moving mechanism, makes structure obtain simplifying.But, because the high and low position of the water-supply pipe that is connected with nozzle and the quenching stand of placing steel tubes all is a fixed, and the diameter of steel pipe to be processed changes, and therefore the axis of the axis of the steel pipe of most specifications and water-supply pipe is not usually not point-blank.In when cooling water spray in steel pipe is carried out, the axis of its circular cone nozzle must be aimed at the steel pipe axis, so the axis of the axis of circular cone nozzle and water-supply pipe is not usually not point-blank yet.Make nozzle and water-supply pipe joint a step occur, increase flow resistance, influence cooling performance.
The purpose of this utility model provides a kind of flow resistance between nozzle and the water-supply pipe that reduces, and strengthens the interior waterworks of steel pipe of cooling performance, to improve the quenching quality of steel pipe internal-surface.
The purpose of this utility model is to realize like this.
Waterworks in a kind of steel pipe, the sealing-ring that comprises water-supply pipe, is installed on the nozzle on the water-supply pipe and is used for sealing between the two, nozzle are the conical partially short tubes of a bore convergent, the offset between its water outlet and the water-in is 0～50mm.
It is the cylindrical straight tube of 10～50mm that there is a segment length at the water outlet place of nozzle, to correct owing to the water (flow) direction deflection that adopts conical partially short tube nozzle to cause, plays the current deflecting effect.The length of straight tube does not have guide effect less than 10mm, greater than 50mm, then can increase the angle of divergence of current.
Nozzle is installed on the water-supply pipe by being welded in the dop and the chuck that have 3-6 claw on nozzle water-in and the water-supply pipe, on it respectively.Preferably chuck is welded on the water-supply pipe, dop is welded on the nozzle.Even the sealing-ring poor sealing like this between chuck and dop, because water spraying direction is opposite with the water outlet direction of leaking, water also is difficult for leaking.
One of chuck and dop, the contact surface that is installed of its claw revolves tighter and tighter for screwing the inclined-plane that direction has ° inclination angle, α=0.5～5 along installing during installation, both has been convenient to load and unload nozzle, can improve sealing condition again.For ease of processing, the inclined-plane preferably is arranged on the claw of chuck.
The advantage that the utility model is compared with prior art had is: because the conical partially short tube of employing bore convergent is as nozzle, the bore of nozzle and water-supply pipe junction is identical, medullary ray overlaps fully, reduced flow resistance, strengthened cooling performance, the uniform quenching of steel pipe internal-surface is improved.In addition, by dop and chuck nozzle is installed on the water-supply pipe, the replacing of nozzle has improved working efficiency when being convenient to handle the different size steel pipe.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of waterworks in the utility model steel pipe.
Fig. 2 is the right side view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 1.
As shown in Figure 1 and Figure 2, waterworks mainly is made up of water-supply pipe 1, chuck 2, dop 3, sealing-ring 4 and nozzle 5 in the utility model steel pipe.Nozzle 5 is the conical partially short tube of bore convergent, and the offset between its water outlet and the water-in is 0～50mm, and the concrete size fibrous root of offset is selected according to the specification of handled steel pipe 5.It is the cylindrical straight tube of 30mm that there is a segment length at the water outlet place of nozzle 5, plays the current deflecting effect.The water-in face down bonding of nozzle 5 is connected to dop 3, and water-supply pipe 1 end is welded with chuck 2, on dop 3 and the chuck 24 claws is arranged respectively.Nozzle 5 was installed on water-supply pipe 1 by dop 3 and being connected of chuck 2.Claw on the chuck 2, the contact surface that is installed of the claw of itself and dop 3 is seen Fig. 3 for screwing the inclined-plane that direction has ° inclination angle, α=3 along installing.Sealing-ring 4 is installed between chuck 2 and the dop 3.
During work,, select the suitable nozzle 5 of offset,, make the axis of the medullary ray aligning steel pipe 6 of its water outlet by being installed on the water-supply pipe 1 dop 3 and being connected of chuck 2 according to the specification of steel pipe 6.Water coolant, is sprayed in it by an end of the steel pipe 6 that is rotating through nozzle 5 from water-supply pipe 1, and general steel pipe 6 ends are 100～200mm apart from the distance of nozzle 5 water outlet ends, distance is too near, and operation is dangerous, hypertelorism, water coolant can not all spray in the pipe, influences cooling performance.
