Abstract
The utility model relates to a spray gun head. The main body is a cylindrical cylinder, the cylindrical cylinder is extended into a ladder conical casing body towards one end, a screw thread structure which is connected with a water conduit is arranged on the other end of the cylindrical cylinder, a plurality of circular spray holes with phi 0.6 mm to phi 0.8 mm hole diameters are evenly distributed on the periphery of the site of a cylinder wall connected with the ladder conical casing body on the cylindrical cylinder, and the axial included angle of the opening direction of each of the spray holes and the cylindrical cylinder is 30 DGE. The utility model has the advantages of suitable aperture size of the spray holes, large working water jet capacity, no separation of ejective water columns and concentrated water impact force. Additionally, the improvement of the angle of the spray holes enables the impact force of water to scale crusts on pipe walls to be reinforced, the utility model is more favorable to flake off scale crusts, and the effect of scale cleaning is more thoroughly.
Description
Technical field
The utility model relates to a kind of lance head of removing tubular evaparator dirt layer, is the improvement of removing the lance head of tubular evaparator inwall dirt layer to existing.
Background technology
Remove the hole for water spraying that the employed lance head of tubular evaparator inwall dirt layer is provided with several Φ 0.4mm at present, the spray orifice opening angle is 45 °, its shortcoming one is that the hole for water spraying aperture is too small, spray flow is less, its result causes nebulizing after the water ejection, and the waterpower insufficient strength is in addition because the spray angle of spray orifice is reasonable inadequately, water ejection back is less to the impulsive force of dirt layer, and the dirt layer is difficult to come off.
Summary of the invention
It is moderate that the purpose of this utility model provides a kind of spray orifice pore size, spray orifice water spray angle rationally, to the strong lance head of peeling force of dirt layer.
For achieving the above object, the technical solution of the utility model is: a kind of lance head, its main body is the cylindrical shape cylinder, extend to form terraced conical shell from its cylindrical shape cylinder one end, be provided with the helicitic texture that is connected with water-supply-pipe at its other end, be evenly equipped with several circular spray orifices on the cylindrical shape cylinder with on the circumference of the cylindrical shape cylinder barrel of described terraced conical shell connecting portion, the axial formation angle α of the opening direction of spray orifice and cylindrical shape cylinder, the aperture that it is characterized in that circular spray orifice is Φ 0.6mm～Φ 0.8mm, and the axial angle α angle of the opening direction of spray orifice and cylindrical shape cylinder is 30 °.
Described a kind of lance head is characterized in that the helicitic texture that described cylindrical shape cylinder one end is connected with water-supply-pipe can be an external screw thread, also can be internal thread.
Adopt the utility model that following advantage is arranged: the spray orifice pore size is moderate, and injection flow rate is bigger, and the water column of ejection does not disperse, the impulsive force of water is more concentrated, the improvement of jet nozzle angle makes water strengthen the dirt layer impulsive force on the tube wall in addition, more helps peeling off of dirt layer, and scaling effect is more thorough.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a lance head structural representation of the present utility model.
Fig. 2 is the impulse force F of water spray and the decomposing force F that the dirt layer is worked the effect of peeling off thereof
1The mechanics schematic diagram.
The specific embodiment
In the lance head structural representation that relates to of the present utility model shown in Figure 1, its main body is the cylindrical shape cylinder, extend to form terraced conical shell 2 from its cylindrical shape cylinder 1 to an end, be provided with the female thread structure (3) that is connected with water-supply-pipe at its other end, be evenly equipped with the circular spray orifice (4) that several apertures are Φ 0.6mm～Φ 0.8mm on its cylindrical shape cylinder with on the barrel circumference of described terraced conical shell (2) connecting portion, the angle α that the axis of the opening direction of spray orifice (4) and cylindrical shape cylinder (1) forms is 30 °.During operation, water under high pressure is delivered to the lance head position through high pressure water transport pipe, from hole for water spraying (4), spray then with 30 ° of angles, by water spray impulse force decomposing schematic representation shown in Figure 2 as can be seen, the water spray angle changes into after 30 ° by 45 °, under the effect of same water spray impulse force F, water is the decomposing force F of impulse force F along rifle head horizontal axis to the impulsive force of dirt layer
1Increase, make easier the peeling off of dirt layer.
Claims (2)
1. lance head, its main body is cylindrical shape cylinder (1), Xiang Yiduan extends to form terraced conical shell (2) from its cylindrical shape cylinder (1), be provided with the helicitic texture (3) that is connected with water-supply-pipe at the cylindrical shape cylinder other end, be evenly equipped with several circular spray orifices (4) on its cylindrical shape cylinder with on the barrel circumference of described terraced conical shell (2) connecting portion, the axial formation angle α of the opening direction of spray orifice (4) and cylindrical shape cylinder (1), the aperture that it is characterized in that circular spray orifice (2) is 0.6mm～Φ 0.8mm, and the axial angle α angle of the opening direction of spray orifice (4) and cylindrical shape cylinder (1) is 30 °.
2. lance head as claimed in claim 1, the helicitic texture that described lance head cylindrical shape cylinder one end is connected with water-supply-pipe can be an external screw thread, also can be internal thread.
